Introduction to the LonWorks technology
At present, in almost every industrial application, there is a trend is away from proprietary control scheme and centralized system. Manufacturers, integrators and owners tend to use based on open technology products, such as out-of-the-chip and operating system and function module products. This technology can improve product reliability, increased system flexibility, built in reducing cost effectively improve system performance. LonWorks technology provides interoperability, advanced technology architecture and speed of product development and predictable cost savings, accelerates the development of this trend.
LonWorks technology is a common field bus technology in industrial control system can be used in the Sensor (sensor bus) Bus, Bus Device (device bus), Field Bus (field bus), and so any layer bus, to design, create, install, and maintain equipment, networks providing solutions to the many problems. In a LonWorks control networks, intelligent control devices (nodes) to use the same communication protocol and the other nodes in the network. Each node through built-in neuron chip to complete the agreement of the monitoring function. A LonWorks control networks can have two to 32385 or more nodes, you can implement features such as: sensors (temperature, pressure, etc), actuator function (switches, control valve, variable frequency drive, etc.), operation interface (display, man-machine interface, etc.) and control functions (air supply unit, VAV variable air volume, etc.). Because you do not need the traditional control systems in the central controller, LonWorks distributed control technology shows very high system reliability, fast system response speed and reduce system costs and maintenance costs. Neuron Chip finish node event handling, and through a variety of media to handle the result passed to other nodes on the network. LonTalk Protocol for LonWorks control networks to achieve interoperability. Neuron Chip and LonTalk Protocol is the core of LonWorks technology. At the same time through the i.LON products to achieve the LonWorks control networks and seamless connectivity of the Internet.

Xinjiapoguanlidaxue city IBMS system functional requirements and characteristics of
Xinjiapoguanlidaxue new University City is located in the city centre, Singapore mass urban centres transformation an important component in the plan, but also the first school in the regionGarden complex.
For normal commercial office buildings, no matter how large scale, its internal activities more or less has a fixed period of time, while the load is relatively fixed and University City is more complex and continuously changing. University City building location relative dispersion, with the students in the University City of activities, each building energy payload (especially the air conditioning and lighting) needs in every place, every single time point are constantly changing. Classroom, laboratory, Lecture Hall is being used every day. Therefore the school timetable, cannot like conventional commercial building as foreseen.
On the campus of energy consumption, air conditioning and lighting equipment for effective management and control is very important. In Singapore's climate, air conditioning and refrigeration cycle consumes energy is the energy consumption accounted for 60 per cent of the Bill. For campus buildings, these diverse and constantly changing load pattern of fine management, only based on the most advanced control technology for the intelligent control system. At the same university city construction is carried out in stages, with the ongoing construction of University City, the control system of the future of sustainable development is necessary to consider the issue.
Select the LonWorks technology to realize the IBMS system considerations
Select the LonWorks technology can take a number of manufacturers, Lonmark certified equipment and equipment integrated into a single intelligent building system to start the main building subsystems — security, lighting, elevators, HVAC, and other systems. By LonWorks smart router and network equipment into the open, seamless network that allows any point from network access to any device that can reduce system acquisition, operation and expansion, etc.
LonWorks technology can provide the entire system for seamless connectivity. In the building of internal, in any location across campus or across the globe, to pass through the network, the license rights to access the system.
Good interoperability guarantees the application of LonWorks technology means that the user is no longer any system or product of a single supplier. Using LonWorks device control system, many devices can use arbitrary topology that consists of a single twisted pair connection on a system providing for system construction, lower installation costs. Device and system control can be simplified by software update, to avoid the hardware, cables, conduit and wiring work, and then configure the significantly lower cost. Extension lines, access device, and then configure it through the man-machine interface. Topological approach is very flexible and can communicate in a variety of media, the Internet easier extended. Regardless of application, technology platforms and infrastructure is maintained. This means that the integrators and end user only needs to have a common set of tools can be effectively reduced maintenance and training costs. Based on the LonWorks device allows you to install all subsystems of a public communications infrastructure, elimination of redundant components, reducing duplication.
Xinjiapoguanlidaxue city IBMS system introduction
Because LonWorks technology foundation of good open, air conditioning and xinjiapoguanlidaxue city mechanical ventilation systems (ACMVS) in the design of different vendors of equipment designed for optimum results. Integrators at least ACVMS chose three different LonWorks device and successfully implements the system of control algorithms. This group of air-conditioning and ventilation systems (ACMVS) consists of two separate buildings of eight freezer, the total maximum cooling capacity reached 5550 tonnes, with more than 110 air conditioning unit, 1500 VAV controller, mechanical ventilation fans and fan-coil.
Applied to the control equipment ACMVS is the Matrix produced by the digital controller. The controller uses the free topology twisted-pair based on LonWorks transceiver with LonWorks technology, applications and other equipment to achieve end-to-end communications, ensure implementation feedback and adjustment required parameters, according to the fluctuations of the need to reduce the cooling load in real-time. For example, when a controller to switch to automatic status, if the load increases, the building of the freezer is initiated, if load necessary, automatically cut off the frozen opportunities. This type of intelligent control is the control based on LonWorks technology platform.
Another major area of energy conservation is to reduce lighting energy consumption. Hall, theaters, halls, etc. and lighting control are incorporated into electronic equipment management system (EFMS). Make an appointment with a set, you can use the time period of the room and the room lights only when someone enters the room is lit, when users leave or exceeds the allowable use of time, the lights are automatically turned off.
In addition to the mechanical ventilation system and electronic device management system, LonWorks system also implements the main line of electricity metering, household electricity metering, monitoring, on the fire automatic elevator monitoring capabilities. Through Echelon's i.LON 600 network server, the field device can and IP backbone to achieve seamless joins, maximum utilization of the campus IT backbone investments, avoid a repeat of the University City. System integrators provide a Web-based interface, you can use the IBMS common browser understanding of system status. When you complete a full integration, based on this platform, Web-based HMI can browse through the system using different protocols of other subsystems.
Xinjiapoguanlidaxue Device Manager Mr. Ho Thim Seng, always seeking to make the campus of equipment running even better solutions. "Control the hardware device is installed just good control of start, our goal is by building the LonWorks controller within the charged object precise control, and thus true energy efficiency, building intelligent campus. "Through continuous mining based on LonWorks technology based system's potential to Mr. Ho ThimSeng-led managers are fully capable of manipulating the system to adapt the current changes in the campus, and saving energy has accumulated more experience.
System energy-saving effect
The University City in July 2005, but the system's energy-saving and intelligent solution advantage has appeared. "In the freezer on and off State, cooling water ranges in 0.5 ° C, while other systems typically ranges in 1.5 ~ 2 ° C", the Device Manager, xinjiapoguanlidaxue Mr. Yat Tan Seng praised the system control appeared in the process. Through his experience and through the LonWorks system good adjustment, the new campus of the overall power consumption is reduced by 20 per cent in the past. Currently, he is the new University City further study how to put more equipment and systems into the LonWorks control networks platform, thereby gaining more control equipment choices, operability and achieve better energy-saving strategies.
The value of LonWorks open systems
Application of LonWorks open systems, not only significantly reduce energy consumption, improve the efficiency of residential comfort and equipment, while extending the range of the device selected, reduces system maintenance difficulty, thus reducing overall acquisition so that end users benefit from it.
Manufacturer through development and other products for compatibility to expand market — other manufacturers as partners rather than competitors. Moreover, the suppliers more focus on functionality, quality and service, without having to spend time and money to develop and maintain their own proprietary architecture; or from the order to consider and many different types of specialized products and system compatibility and time-consuming effort.
System integrators using fully compatible many manufacturer's product, they have more choices to customers more satisfied. Design and deployment easier, because the integration of parts is reduced, but are peers. Does not require gateway and customized software, no single point of failure or the need to learn to use third-party tools. System deployment faster, with fewer problems, thereby increasing customer satisfaction, and therefore can also benefit from a LonWorks open systems.
【 Weak current College 】 shopping center management industry characteristics and trends
Shopping Centre in Europe and the United States through half a century later, to become a hotspot for commercial development. Since 1996, Guangzhou Tianhe city officially opened, in China's coastal waters and some developed cities emerged a shopping mall, the most advanced retail form. According to China General Chamber of commerce statistics, it is estimated that by the end of 2003, China opened shopping centre approximately 200, total building area of over 30 million square meters. But the author believes that currently scheduled Mall is far from achieving this quantity. Since the financing, planning, design, business positioning, government regulation and other reasons, in particular on the Mall, the most advanced retail form the essence of the deviation of the shopping centre management experience, leading to massive shopping centre aborted, or barely opened with their minds completely deviated from. This article is to unify the property property Mall (SHOPPINGMALL) as samples, shopping center management industry and its trends.
First, the shopping centre management industry characteristics
And dispersion property corresponds to the residential property management, commercial property typically include shopping centers, shopping malls, office buildings, hotels, etc. directly to business of construction. From an administrative standpoint, the mall management contains most of the content, but also the most complex. The most basic general property management content, with the property management industry's basic features, but also has a very clear business planning, business management, Enterprise behavior.
First, a shopping centre management has the basic features of the property management industry, but the objects in the management, operation of complexity, etc with dispersed ownership of residential property, even compared to other commercial property has a very big difference. At the same time, the shopping centre management in basic property management, based on the combination of comprehensive business and retail management. To the Tianhe City shopping centre, for example: Tianhe city Guangdong Timon (Group) co., Ltd. holds 100% ownership by the Tianhe city property management co., Ltd. Management. A total investment of 12 million Yuan, covers an area of 4.4 million square meters, construction area of 16 thousand square meters, of which 8 stories for commercial undertakings, about 10 000 square meters, 2 underground for car parks, an annual turnover of about 50 billion yuan. Venue including 9000 ton of air conditioning units, 62 of escalators and elevators, 28 2000 Department of vertical door capacity-controlled telephone system and automatic fire order maintenance system. Farm business tenants of 320, staff of about 8000 people. 04 year, 1 million 2 million passenger trips, the flow of 150 million times, commodity, the amount of material in and out of the 50 million tons. Annual equipment, facilities maintenance projects over 21000, maintenance projects over 25000. Average daily passenger volume 32 000. Equipment maintenance, cleaning, gardening, renters management, customer service and management, security, and so on, are the most basic property management industry, but its management complexity is much higher than the same size of other commercial properties, residential community. Therefore, the shopping centre management has the basic features of the property management industry, shopping center management company first, property management companies.
But only for pure property management, the shopping centre management because of differences in the demand for the service object, behavior of to be distinct, and other factors, has its distinctive features: service objects include owners, rental businesses and customers. Owners hire a property management company is to create sustainable improvements to the shopping and business environment, reasonable commercial portfolio and continued timely adjustment to constantly improve the value of the commercial shopping center, the reasonable control of daily operating costs. Relative to consumption in the residential property management fees, shopping center management fee properties is a typical investment behavior. Property management fees paid by lease commercial tenants, but due to the owners of leasing and management fees, management fees bundled with approved standards approved by the owners and transfer payments to the management company. Due to the actual needs and the owners of investment behavior, shopping center management fees standard much higher than other commercial property; the tenants on the requirements of the property management company is the ability to create first attract customers integrated environment to increase operating earnings, the tenants themselves on environmental requirements and the experience has been relegated, rental and management fees on the tenants are cost items, tenants more concern is the sum of both high and low level of the fee is not very sensitive; customer is typical of the ordinary meaning of the consumer, the requirements of a good shopping and leisure environment, perfect, reasonable prices of goods and services, a good business reputation, etc, because of its non-owners, and mobility, short-term consumption (and many consumer not opposite), on the evaluation of the property management company is to vote with their feet, and indirectly through businesses and property owners to decide the fate of property management companies.
Second, the mall management industry trends
Shopping centre management is the most basic general property management content, with the property management industry's basic features, but also has a very clear business planning, business management, corporate behavior, is the fusion of the traditional sense of the property management and commercial management with distinct characteristics of the emerging industry specialization.
From normal operational perspective, because the basic functionality of the shopping center is to provide consumers with the consumption of pluralism, diversity, living conditions, meet people shopping, leisure, entertainment, sports and so on material and spiritual life. Therefore, the central task of the shopping centre management is as market needs change, and constantly adjust and optimize industrial structure, industry structure and brand structure, adjustment of the business combination to form a reasonable, improve, coordinate, to the maximum extent to meet consumer demand for business environments, providing the leasing business owners create maximum business benefits and business value. Therefore, the shopping centre management, both to complete the traditional sense of the highly complex property management content, reasonable control huge daily operations and maintenance expenses, while at the same time on dining, entertainment, cinemas, Department stores, supermarkets and all kinds of professional and specialized shops, on all types of goods and services have full understanding, and combinations of types, styles and combinations of the basicLaw, the day-to-day operations of the basic requirements, have a thorough understanding.
In marketing, customer relationship management, brand management, commercial and cultural exhibition, shopping center management and traditional meaning of property management, and retail sales also has great differences, limited to space, not expand.
Due to the professional management of the company's day-to-day operations to the shopping center have a thorough understanding of the shopping center from market research, project orientation, planning and design, layout, equipment configuration and control is essential to carefully listen to the advice of a professional management company. It can be said that no professional shopping centre management company's full participation in the shopping centre is very difficult to guarantee that construction and operation is successful, the impressive return on investment. As such, professional shopping centre management company has been leading to full participation until the shopping centre's planning, construction, leasing and operating direction.
At present, the shopping centre management company number is from a traditional property management company or a business management company, large retail enterprises serves. Traditional property management companies are managing multiple property, and related businesses in a variety of mixed operating companies, according to the Division of property function, this kind of company's specialization is also far from being able to reach the shopping centre; commercial management companies or large retail enterprises as property management and lack of experience, the management of the shopping centre '. At present, the domestic standard, professional shopping center management company. At the same time, since the relevant government departments, industry sector, industry regulations, such as the shopping centre of planning and design, delegated administration, management, cost accounting standards, service qualification, training and qualification assessment in areas such as competition, managing, directing and regulating effect enough strong domestic shopping centre planning and construction, operation and management have a confusing situation, a wide range of issues. But in the end or the deviation of the concept and the lack of management. The basic principles of the shopping center is sold not only rent, unified management, management management proceeds and property value is a long term investment management process. The Mall is the essence of the real estate business and non-commercial real estate, that is, on the basis of the real estate business. And today sold many shopping centers take segmentation with anti-rent of business, this in order to obtain a cash advance sale shop practices ultimately led to the shopping centre turn into small commodities market, shopping centre, this complex commercial aircraft carrier is very difficult to operate successfully, the owners of investment income expected Basic is impossible. Arising from the various social and economic issues will be very difficult to solve. Shopping centre management company in the search industry in the process of belonging, there have been similar to hotel management industry development trend of the path, that is, the basic property management on the basis of the integrated business management company direction and seek industry belong. Currently, the country is mainly limited by controlling loans and land development to regulate the shopping center industry. In addition, think more simple, direct and effective measures to preserve the integrity of the property right in the shopping center property, which is not allowed to sell the shopping center segment, but you can use the full property of the property for mortgage financing or other forms of debt and equity financing. In this way, investors will focus on the long-term management of shopping centers, the existing problems will not continue. The State property management industry bodies can be found in the shopping center management enterprise qualification level assessment, evaluation, shopping center management honor industry dynamic tracking, practitioners qualification and training, developing specialized standards and policies to guide and regulate the mall management industries.

【 Weak current College 】 free design decoration of shady
With the decoration style of the individual pursuit and maximum utilization of space of consciousness more and more weight, many people are going to spend money to make professional designers to design their own home. Now many home businesses are like playing out the "free design" to attract owners, this article provides you expose free design decoration of the inside. Inside a: free decoration design easily lead to "wholesale business," Mr Director explains, a design qualification card decoration enterprises should adhere to the decoration, decoration designers avoid decoration design fee is a violation of etiquette and demeaning. However, the enterprise to "free decoration design" as a marketing tool, is a legitimate means of competition, cannot be cancelled. However, in most cases, the "free design" level is very questionable. He explained that, in fact, designers of decoration design costs into the construction cost. In this way, the decoration costs how much in the "free" under the banner of become blurred. Consumers spent more odds thought is to enjoy a free lunch. At the same time, the name of the free provision of services, once they encounter problems, designers are not responsible. Shady II: free decoration design brief was simple decoration, the most important is the decoration figure, set decoration design drawings at least need to include the original room reconnaissance plane figure, reconstruction design and so on more than 15 sheets of the drawings. A designer to accomplish these drawings, at least 20 business days. Except copying, "clone", a designer a month can do 2 design, Director, "free" after the construction drawings, often out of the original architectural drawings, design the floor plan and decoration, as well as drawing the circuit diagram, but other decoration design drawings depends on whether or not charges. To the reconstruction of hydropower, "free" is a common practice: construction field painting, even further out of the zoning plan completion rates. Due to the construction, decoration owners don't see forming of hydropower reform plans for home decoration companies in the decoration of additional planted in random. Charges decoration figure up to 100 sheets at present, more and more owners have begun to accept the "design" of the concept of charges, you pay you can enjoy what services? a designer shows his latest work: a stack of thick decoration design drawings, there are more than 80, detailed design content to strong electric, electronic, switches, distribution, ceiling, furniture, accessories ... Every detail is drawing detailed maps. Designers, like this design decoration drawing, the owners do not need to worry about out construction disputes, because each Department and construction are in black and white on paper, while construction team is also very easy, as long as fully in accordance with the drawings. The more valuable for design, construction drawing finer, more owners peace of mind. Of course, design is the need to sign the charge specifically agreed, at the Shanghai interior designers employed management procedures, defined the four-step Design Premium, design by progress payments respectively 20%, 50%, 20% and 10%. Consumers each billing are required to have the parties signature confirmation. After the signing of the contract, the consumer pays the fee for the first phase of the design design price of 20%; preliminary programme confirmed, then pay NPP design fee is 50% of the total price of the design; the second design drawings confirm before payment of the third stage design fee is 20% of total price; a full set of drawings completed, consumers pay off the balance, design fees to produce design party bound drawings 2 sets, one set of retention, a set of turnkey construction. So, consumers chose to charge design received the service guarantee.
Recently, the Shanghai City decoration Association established the Shanghai interior designers employed temporary measures "clearly pointed out:" stick to design the paid service, the design must charge ... Free design behavior to unfair competition entered the designer credit file. "But currently are not explicitly restricted free design. To this end, the decoration industry management office Zhu ping health officer believes that "free design" does not guarantee the level of design, design programmes also tended to be lax, consumer choice must carefully.

【 Weak current College 】 smart home wireless RF (HomeRF) technology
HomeRF technology introduction
As wireless technology programme, HomeRF replaces the need for cable laying expensive transmission lines in the home network, the network devices such as laptops and application provides roaming capabilities.
In the United States Federal Communications Commission (FCC) formally approved HomeRF standard HomeRF Working Group had before it, as in the family context for voice and data wireless communications to develop a specification that is shared wireless access protocol (SWAP). SWAP specification advent, in addition to the extended high-performance, multi-band cordless telephone technology, but also greatly facilitates low-cost wireless data network technology development. However, HomeRF occupy with 802 .11b and Bluetooth same 2.4G frequency segments and too limited in functionality, and then the family application, taking into account the Office areas have 802.11b achieved status, I am afraid that in future more difficult.
In China, there are also some smart home company using radio frequency technology, often mainly uses 433.29MHz, this technique has the advantage that some products do not need to re-route use point-to-point radio frequency technology to home appliances and lighting control, installation settings are relatively easy, mainly used in the implementation of certain electrical equipment or lighting control, cost is moderate. But the system function is relatively weak, compared to a single control mode and vulnerable around wireless device environment particularly in the frequency and obstructions interference and shielding; more applicable to the newly renovated and has been renovated.

74, project settlement is building units and construction units in accordance with the project progress on the completion of some project realization of monetary payment behavior
75, budget fixed by the principle: according to the Community average to determine the applicability of the principles, concise, stick to the unity and the integration of different
76, budget fixed compilation steps: preparation phase — information gathering phase-fixed compilation phase — fixed the final approval stage — modify, process the data stage
77, construction fixed units of measurement in accordance with the procedure and the General construction process; and budget fixed units of measurement are mainly based on sub-project engineering and structural elements of the shape features and variations to determine
78, of two methods: the ⑴ production quota; ⑵ on-site observations based on the determination of data (field-weekday realist approach)
Number 79, artificial shadow days including basic labor (complete fixed measure single-key labor provided by labor quota + should increase the amount of helpers additional labor +) and other labor (ultra distance labor + secondary employment + artificial magnitude difference)
80, artificial magnitude difference = (basic labor + secondary employment + ultra distance labor) * artificial magnitude difference coefficients
81, actual engineering field distance over budget quota determination distance, Can be calculated second cartage
82, material consumption (determination into field observation and laboratory method) by purpose is divided into: primary materials, auxiliary materials, working materials, other materials (material consumption = material net amount (1 + rate))
83, budget fixed machinery construction consumed rent = fixed machinery consumption of rent (1 + mechanical magnitude difference coefficients)
84, proportion of scattered small mechanical press work quota calculation introduced class members, to mechanical charges or other fees that are no longer machine column the number of rent
85, years non-job shadow days: refers to workers in learning, training, mobility, visiting relatives, leave, because climate impact, women children, 6 months or less sick leave as well as production, marriage, bereavement, the number of days in the year should work and not the number of days of work
86 days, effective work years should work days =-year non-working days
87, impact factors of artificial price: social average wage levels, living consumption index, the composition of the artificial price, supply and demand in the labour market, the implementation of social security and welfare policy
88, impact materials budget price change factors: market supply and demand changes, material changes in the cost of production, circulation and supply system, the transport distance and transport methods, the domestic market will have an impact on the price of imported materials
89, materials budget price means the materials from its sources to arrive at the site of the library after the warehouse general average price. General material price (factory price, imported materials arrive on board, sales departments, wholesale and retail price), and marketing departments handling, packing, shipping fees, purchasing and maintenance costs;
90, materials budget price = (materials and marketing departments of the original price + handling fee + packaging + shipping fees + transport loss) (1 + procurement and custody rates)-packaging materials recycling value
91, materials supply price = material to supply departments handling the original price +
92, packaging materials, packaging and recycling value = price * proportion * recovery value of recycling ratio
93, migration and incidental expenses (freight, in accordance with the other cities (including transfer fares, handling, transport, insurance, freight) and city freight) refers to the material by the purchasing or shipping point to the construction site of the warehouse or storage site, including site search transit transport occurs during all expenses and transit tolls, including shunting barge fee, handling fees, transportation costs, and additional costs, etc.
94, purchase and maintenance costs = materials transported to site warehouse prices * procurement and custody rate = (materials and marketing departments of the original price + handling fee + packaging + shipping fees + transport tear) * procurement and custody rates
95, construction machinery rent price includes: depreciation, cost of repairs, often repairs, Ann (enclosed) clearance fees and other charges (non-farm freight), fuel, labor, power, vehicle and vessel usage tax, etc.
96, religious dramas depreciation = mechanical budget price * (1-residual rate) * loan interest factor/durable total budget rent; machinery for ex-factory price and incidental expenses of calculation; loan interest coefficient = 1 + (n + 1) I/2; durable religious dramas that mechanical life, can be divided into technical service life and economic useful life (used in the same fixed quota), durable rent = depreciation life * years working class = overhaul interval of rent * overhaul cycle (where the overhaul period = lifetime repair count + 1)
97, religious dramas overhaul costs = a major repair costs * life-cycle repair times/durable total rent
98, rent fuel power consumption = (actual number * 4 + fixed average + survey mean)/6
99, engineering price generally refers to the construction and installation the project's budget price and unit price estimates; including artificial fee, material fee, machinery;
100, part of the project price: press using object content architecture engineering price and installation engineering price; by purpose into budget price, estimates range by using the unit price; sub-regional unit price and the unit price supplement; case basis at a fixed price and unit price; the price supplements the integrated level divided into basic direct cost price (artificial fee, material fee, mechanical), full-cost prices (labor, materials, machinery, onsite expenses, other direct costs and indirect costs) and the full price (labor, materials, machinery, onsite expenses, other direct costs, indirect costs, profits and taxes)
