【 Words】 intelligent Community system integration integrated LonWorks control networks

From simple conversational system, to today's intelligence community, after a decade of setbacks in the development, application of intelligent community and industry have come to a new phase. Although the current swept through the global financial crisis on the real estate industry, some real estate sales stagnated situations occur, but we believe China's urbanization trends will not change, the intelligence community building will experience their cocoons exercises of butterflies and soaring development process, therefore, in the current financial crisis situation review and discussion of intelligent technology and development, while strengthening the technical updates and system perfect, long-lasting development of the industry relevance.

This article on Intelligent Community system of review and analysis, intelligent community from system integration to the new integrated system changes, this change is the development of the industry to the inevitable trend of a certain period of time, will lead the new product architecture and development mode, and the vast number of integrators, manufacturers and real estate developers.

1 intelligent Community system integration situation and problem analysis
Residential district intellectualization system typically includes security, management and monitoring, information network three subsystems, including security subsystem also includes residential alarm unit, guest speaker-appliance, perimeter defense, alarm, CCTV monitoring devices and electronic patrol equipment, management and monitoring subsystem including automatic meter reading systems, vehicle access and parking management, emergency broadcasting and background music, property management computer system and device monitoring device. The above ten molecular system and telephone, computer, television networks, formed the General intelligent community of the main components.
From 1998 the Ministry of construction publishing the apartment community intelligent demonstration project construction main point and technical guidelines (draft) ", a Chinese community intelligence and family of intelligent development, because the actual situation in the community, International does not have to get a complete system, and the emergence of a number of systems of reference and pieced together, forming a unique Chinese community on system integration mode.
In these systems, the security subsystem and management monitoring subsystem functionality, usually by independent molecular system implementations, and community management level through a physical connection to achieve linkage function and pass information platform for data sharing. This is commonly referred to as system integration.
This system integration features:
(1) features correspond one-to-one with physical subsystems subsystem;
(2) system is a bottom-up construction, construction completed for each subsystem, the Centre implements limited integration;
(3) various subsystems use different manufacturers, different protocol standards;
(4) each system of pipelines, equipment, operation, maintenance, are independent.
During the preceding ten years, which we refer to as the traditional "system integration" is familiar to the General engineering company, become intelligent Community system construction of mainstream models. When used as a natural, people often don't go into its inherent not reasonable factors. In fact, intelligent traditional system integration has obvious disadvantages:
(1) the structure of complex
This includes the design of complex, complicated, complex pipeline, maintenance, expansion to phenomena such as. For example, a set of intelligent community of the programme, involving a dozen separate systems, hundreds of different brand models, system construction, construction, operation and maintenance after a larger problems, often building party most headache. This is obviously not conducive to promoting the popularity of the system.
(2) in a bad economy
* Function
Due to the relatively intelligent community development time, various subsystems are from other commercial building in transplantation, for example, family security, perimeter defense and TV monitoring system from a financial, cultural and military fields, equipment monitoring, parking management and network cabling is introduced from commercial buildings, these systems are powerful, complex structures, the cost is high. In fact, the Community system often requires more complete, but the functional requirements of a single system is not high, while the consumer is not a professional, request interface directly, simple operation, those special products in function of the waste at the same time and can not be achieved good results.
* Cost
Due to the complex system and redundancy functionality, resulting in system design, piping, installation, use, maintenance, and other aspects to form a number of waste, making for a long time considered the "smart House" is inexplicable and expensive things, coupled with the application in General appear some problems, so the exclusion occurs, causing adverse effects.
(3) reliability is not strong
Because the system is flattened forms but also more complex, plus the domestic manufacturers product research and development is still at an early stage, leading Intelligent Community system in the building and use frequently appear in one way or another, reliability has become the system critical problems, and also restricting the development of the system.
(4) you cannot interchange interchange
Due to the different subsystems of different manufacturers ' products, plus industry-standard, existing standards tend to focus on the functionality, interoperability, not parts of the interface, or harmonization of requirements on the overall system does not have a clear idea of the network infrastructure, thus causing subsystem no connectivity between each other, different manufacturers ' products are not interchangeable, if a product is broken, and only to the manufacturer of the replacement, if the manufacturers fail, the entire system will be completely replaced.
Early years industry media intelligence community satisfaction surveys, the results of only 40%, most of the users of the community and family smartThe system is not satisfactory, many people wondered, but in my view, given the profession and industry just over ten years of history and the structural problems that occur a lot of dissatisfaction with the situation it's not hard to understand.
So, where is the way out?

2 from system integration to the transformation of the integrated system
Although the various manufacturers are in further improvement of product quality, however, this alone is not enough, because the structural problem is not solved this problem cannot be resolved to be fundamental. So, we made from system integration to the transformation of the integrated system.
So what is the "integrated system"?
Integrated system is built on a unified network platforms, multi-function fusion simplistic system, characterized in a network with standard interfaces attached to different multi-function terminal, past need multiple independent systems to complete various functional requirements.
Integrated system of concepts in the recent literature will also be reflected. In 2007 the implementation of national standards GB/T50314-2006 the intelligence architectural design standard "first" intelligent integrated systems "(IIS) concepts, i.e. IntelligentedIntegrationSystem" will be a different function in construction intellectualization system, through unified information platform integration, to form an information gathering, sharing and optimal management of integrated functional systems for the development of the integrated system provides policy guidance and theoretical basis, and practitioners.
Integrated systems and system integration with notable differences:
(1) the system integration is a bottom-up structure is to build each functional subsystem, and then build the integrated network; and integrated system is a top-down structure, is to establish control of the network, and then extend the functionality of the subsystem;
(2) system integrated front-end device is a single function, closed, not scalable equipment; and integrated system of the front-end device is a multifunctional, open, you can extend the equipment;
Obviously, for the last section of system integration, integrated system has the structure, economic savings, easy maintenance, efficiency, etc. At the same time, the effective implementation of a system of comprehensive monitoring and management, implementation of the relevant subsystem optimized collaborative and linkage, simplifies the system architecture, design, construction and acceptance, shorten cycle and easy system operation and maintenance, and the ability to form an efficient, integrated management platform, the realization of system of remote maintenance and diagnosis of the repair.
Figure 1 shows these two different system architecture of change. Visible, although only two words of order exchange, it is a way to address current intelligence community have encountered bottlenecks in good ways.
3 implementation of the integrated system of network infrastructure
Of course, you want to implement this conversion is conditional, first on intelligent community features require a clearer analysis and positioning; second, it is necessary to establish at Community level to control a network of highly reliable; third, it is necessary to have a common interface for multi-function smart terminal. The above three conditions, the smart community development is difficult at the beginning. However, nowadays, intelligent community has entered into the second period of ten years, it has accumulated a great deal of experience and lessons of the project, various network control technology has been applied from understanding toward the, equipment manufacturers are increasingly rich and strong, we have from the traditional system integrated to the integrated system of transformation of the Foundation and capacity.
First of all, from the previous simple subsystem set out to use fusion and integration technology, as far as possible, system optimization and simplification; Secondly, the use of digitization and networking products and systems more and more, to reduce the cable and the benefits of shared resources; Furthermore, a telephone, TV, broadband, structured standardized mode is used and identity, which in turn requires intelligent systems network calls for Standardization is increasingly strong.
Intelligent control networks is an integrated system of basic and General key, residential buildings, household, long distance, outdoor environmental complex, in the control network transmission of signal types, require more complex, is equivalent to the PDS in "complex subsystems", that is the most difficult to implement. System after is security, reliability and real time, alarm system signal to safely delivered to the alarm Center, meter reading data to ensure reliable upstream, also requires the system to be able to deal effectively with conflict signals, such as households to ensure at the same time alarm does not lose the data. At the same time to adopt network block and quarantine technology allowing single-family failure will not affect the overall functionality. Therefore, it is important to select a widely accepted and proven effective and reliable communications protocol.
Ethernet and field (bus) control network is currently applied to the intelligence community integrated system of major network form. Which is based on TCP/IP Protocol Ethernet, voice of the higher should be the future direction of multi-network, but for large intelligent control networks WINS is not rare, in the alarm network is also controversial, so do not detail. For perennial experience of the PROFIBUS control network, we can responsibly say that can become a smart community integration system optional reliable network infrastructure.
LonTalk protocol based LonWorks control networks is a universal, open, interactive and control network, with many of the manufacturers of existing products and different network protocol device networking. In the community establishing LonWorks bus, you can add an existing smart device networking, at the same time, facing the future, you can access all kinds of accepted LonTalk Protocol of smart devices and energy and IP LAN integration. Standardization administration of China (SAC) LonWorks technology has been translated into the following control network technical standards (national standards): GB/Z20177-2006 LonWorks control networks technical specifications; GB/T20299.4-2006 the construction and application of digital technology for residential area "part 4: controlling network communication protocol application requirements.
No matter what kind of control network forms to reliable transmission signal, and a standardized interface, can become intelligent integrated systems and carriers.

4 integrated system architecture content
When establishing a community control network, different positions in community settings are different or same multi-function intelligent Terminal, you can implement the entire residential area of integrated systems.
System architecture and configuration is as follows:
(1) community management centre: the use of integrated computer control host, intercom, burglar alarm, television monitor, information release, remote meter reading system, intelligent control and centralized management capabilities;
(2) the community or the cell door: multifunctional Talkback host, access card, video intercom, traffic control, elevator control, electronic checks, and other functions;
(3) household: the use of multi-function intelligent Terminal, intercom, alarm, information received, remote meter reading, household appliances control, features such as automatic call;
(4) community equipment Department: multifunctional control module, module or DAC, remote control, status display, timing and mode of control functions.
Top visible, very large and complex multifunctional system becomes very simple. In fact, intelligent community itself is a function of the direct and simple system, but we have no experience as a result of the initial and the system is complicated, the system integrated into the integrated system is a simplified process. And the Unit hosts, intelligent Terminal and control module using standardized interfaces design, different manufacturers and products are interchangeable; its functionality can be extended when the need for additional functionality, no excavation pipe network, simple, reliable, convenient and economical, it is not difficult to see its future development potential.

5. concluding remarks
In this article, we discussed the intelligence from system integration to integrated system changing trends and implementations, this is a great progress. However, not implemented this transformation after once and for all, and later there is still a long way. Because we know that when an industry network and terminal can be detached, it can be said that the industry has matured, the standardization process is also the basis for the rapid development of the industry, I believe that the intelligence community and intelligent family will go through this step, from system integration to the transformation of the integrated system is the only way of achieving these standardization is the development of the industry.
