【 Weak current College 】 smart residential area of weak electricity system (below)

4. management system

Residential areas set wuyeguanlizhongxin, in order to facilitate the management, combined with the Security Center, property management including water electric automatic meter reading and billing system, parking management system, building automatic control system and automatic control system for electrical appliances.

4.1 road water electric automatic meter reading and billing

Automatic meter reading system consists of onsite data acquisition, Management Center management hosts and transmission cables. In the three tables a centralized location (such as a household) set up data collector, water meters, electricity meters, gas meters (should be electronic, preferably a digital meter) reading ready to collect and store in the memory, the data collector uses the bus and the central administration computer touch, Management Center to the vitality of billing, printing, or you can use the Bank's data network to the various functions of management, the realization of electronic automatic meter reading to households from intermediary.

4.2 parking management

Residential access, set the camera-aided vehicle management, set the parking management system, the system is composed of barrier gate, IC card reader, managing computer and transmission cables. The owners hold the intelligent IC card, IC card read-write machine (effective distance) light Akira, the system can complete the inspection, records, accounting, billing and other calculations, automatically opening and closing at the barrier gate; for visiting car, paid by the person on duty, a provisional card management machine automatic timing, accounting fees, a high level of transparency. Private garage can also set the IC card reader with the garage door automatic linkage, the reader can keep detailed records of private cars, only multiple information showreel before release. This system and the latter service information (IC card system) uniform implementation.

4.3 building automation

Building automatic control system consists of the management host, implementing agencies, and various types of sensors and transmission cables, electrical and mechanical equipment for the community to achieve automatic control. Computer control and management as the core, various types of sensors and actuators on the regional electricity (air conditioning), lighting, elevators, water supply and drainage, spray irrigation, etc. to be detected, the implementation of decentralized control, centralized management, power and reduce the maintenance staff, extend equipment life, etc.

4.4 appliance control

Automatic control system for household appliances in households, by a certain program control appliance switches, remote control air conditioning, audio, curtains, household control signal by each household lighting distribution box lighting branch circuit transmission. The system is the icing on the cake of intelligent systems, suitable for high-end residential villas.

5. service system (IC card system)

Household work easy, fast, life safety, comfort is high level direction property management commitment. Service system is to let tenants through one IC card can be in residential areas, free parking, convenient access to the consumer, such as fee for one card. IC card means the non-contact IC cards, contactless IC card, also known as RF card, it succeeded in radio frequency identification technology and IC card technologies to solve-powered (no power in the card) and contact the puzzle, IC card comes with large line containing encryption control logic and communications logic circuit, through the antenna on the card information for read and write, communication protocol using half-duplex communication pattern, the advantages are as follows: A), high reliability and long service life (totally enclosed package, waterproof vapor, static, vibration, electromagnetic interference). B) easy and fast. C) conflict prevention, anti-jammings well. D) wide, the smart card. E) small size, light weight, low cost, easy to carry. IC card system and the aforesaid patrol system, parking management system can be implemented. Because the IC card with 16 different encrypted sectors, the IC card sector gives a different value, you will have different functionality for different identities. In clubs, entertainment set IC card consumption station, in Central Administration also set IC card consumption station, convenient for household consumption and to pay the costs. This card also can establish access control, household archives and household medical files, etc. There has been extensive use of IC card, at the same time markets are beginning to use the lower cost of ID cards.

6.l fire protection system

When residential areas including senior or high-rise residential, residential areas within the fire control centre, the building zone alarm and fire control signal, fire communications signals and fire Centre control hosts (or linkage Cabinet) networking, fire control centers generally combined with the Security Center, in order to reduce on-duty staff.

6.2 security intercom

Residential areas set low power wireless intercom, vitality centre based in security, the handset by security guards carry, so that security guards and Security Centre contact, its communication protocol-simplex mode, radio frequencies should be in the radio regulatory Commission "applications.

6.3 background music

Residential areas for improvement in the human landscape, you can set the amplifiers in Central Administration, public places speaker set, main roads, entertainment; indoor use ceiling speakers, outdoor use column speakers.

6.4 smart Center

Security Centre and Central Administration in-built as smart Center (including the fire control centre), in the present three networks (voice, data and video) are not integrated, intelligent Centre should consider Telecom optical nodes, cable television in room and broadband data communication engine room equipment housing requirements. Currently, the most intelligent district, Shenzhen (in particular the general community) widespread shortage of communication workshop, the inconvenience of the broadband access business. Smart Centre to set the system host and control devices, through computer multimedia Chinese system, alarm software, database software and test software for residential areas controllers, sensors, unified registration, enrollment management, a scheduled inspection, the simulation shows the status of all components in the region, in particular the alarming state.

6.5 system integration

System integration is a smart residential area more important links, mainly refers to the use of computer networks and software subsystems integrated, create digital communities that actively promote informatization。 System integration includes two parts, one is the formation of the residential areas of computer networks, the second is to associate each subsystem integration, let the weak electricity system in residential areas into an organic whole.

6.6 communication pipeline

Various subsystems within the intelligent community, various cables, optical cables and wires and also more; residential areas set up communication channels, all outdoor cables are laid in the communication pipeline. Communication pipeline with hard plastic or f114 double wall wave Timor pipe, duct capacity apart from the need to implement intelligent system cable conduit occupied, you should set aside 30% of the amount of standby to launch new business pipeline capacity to 4-8f114 suitable, check and hand hole. Currently, Shenzhen smart residential areas (in particular the general community) outdoor pipe widespread capacity is small, about 2-3f114.

7, summary

As microelectronics, telecommunications technology progress and the main idea gradually spreading, intelligent residential areas of weak electricity system also has further increased trend; select different subsystems integrated the formation of various degrees of smart residential area, it is particularly important in the overall planning. Developers and planning units directly before the construction drawing design, construction, planning to leave room for the development, implementation of the various subsystems step-by-step. On the floor in the piping and wiring, outdoor pipe, the region should set aside sufficient communication building, software programming is a system reserved extension interface; let smart residential area of the weak electricity system into an organic whole.
