"Intelligent residential area" refers to a new type of residential area through comprehensive configuration of various functional subsystems in the residential area, with integrated wiring as the basic framework and computer network as the management of various equipment in the area. A high and new technology vigorously promoted in the construction is the combination of multidisciplinary research results of building technology and computer technology, network technology, communication technology and automatic control technology. On the one hand, this technology provides the property management department with scientific and efficient management methods and methods, on the other hand, it also provides residents with a safe, comfortable, and efficient modern living space and environment.

The intelligent residential area system is mainly composed of three parts: security alarm system, network communication system, and property management system:

1. Security alarm system

The security alarm system is one of the important components of a smart house. The smart house security system has a high level of automation technology and perfect functions, with high safety and reliability. The anti-theft and anti-disaster alarm devices of each household unit are connected to the monitoring computer of the community management center through the network system to realize uninterrupted monitoring. Security alarms include: access control system, infrared door magnetic alarm, fire alarm, gas leak alarm, emergency help, closed-circuit television monitoring, surrounding anti-overal alarm, intercom anti-theft door system, etc.

(1) Access control system: Install a pair of door magnets in the central position above the door frame of the occupant's room door. Residents can use the key to open the door normally. If an illegal prying door occurs, the access control system will send an alarm signal and pass the signal to the home anti-theft host The community property management center tells the building on duty and which type of alarm occurs in which household, the watchkeeping staff can dispatch security personnel to the scene to deal with in time.

(2) Infrared door magnetic alarm: install infrared detector (or glass break detector) and door magnetic switch alarm at the position of easily invading gate (or window), when suspicious person pry the door (open the door) or break the window and want to enter When indoors, the monitor enters the working state of people and emits sound and light alarm signals, and at the same time displays the alarmed buildings, units, floors, the specific location of the residents and the basic information of the householders on the monitoring host through the monitoring network system.

(3) Automatic fire alarm: Intelligent smoke detectors are installed in residential stairwells, elevator front rooms and living rooms, etc. The intelligent smoke detectors are connected to the anti-theft and disaster prevention monitoring network system of the community management center. When a fire alarm occurs, an audible and visual alarm is activated, informing residents and the community management center to quickly take measures to ensure the safety of residents ’lives and property.

(4) Combustible gas leakage alarm: Install gas leakage alarm in the kitchen and bathroom. When there is gas leakage, it will trigger the alarm and automatically close the pipeline valve, start the audible and visual alarm, and send it to the community management center to notify the residents and community management center. Take prompt measures to ensure the safety of residents ’lives and property.

(5) Emergency call system: The emergency call button is firmly installed in the living room and bedroom of the house. When an emergency occurs in the home, such as serious illness, burglar break-in, and you need help, as long as the emergency call button, the management center receives the number 1 You can immediately send people to the scene to help residents get timely assistance.

(6) CCTV surveillance: install surveillance cameras in important places such as the entrances, trunk passages, parking lots, and walls of the community, and transmit the situation of the monitoring area to the management center in real time by image. The on-duty personnel can learn about the situation of these important places and store the video through the TV wall at any time.

(7) Peripheral anti-overfall alarm: set up an infrared radiation alarm system on the surrounding wall of the community to build the first protective barrier in the community. When someone illegally crosses the wall, it will call the police and trigger the perimeter camera to track the camera and record.

(8) Intercom anti-theft door system: a building security door intercom system is installed at the staircase of each unit in the community. Each household is equipped with a walkie-talkie that can control the building security door. Visitors can use the intercom system to communicate with the visited resident. Security personnel can Talk to the residents directly and confirm the identity of the visitor before the visitor can enter the community. In high-end residential buildings, a visual intercom system for building security doors can be used.

2. Network communication system The network communication system is the god system of the intelligent community. It connects the terminal equipment and network management center of each functional subsystem in the community into a network, and interconnects with the Internet to provide the information transmission channel for the community. Bridge to provide residents with complete animal husbandry management and comprehensive information services.

First, the regional network of residential quarters should be established, connecting various subsystems, and then connecting the regional network with the public network. The comprehensive wiring of the community should fully consider the needs of each subsystem, and incorporate the transmission of data communication, intercom, call, alarm, equipment management and other signals into the bus system. The network transmission media connecting each household in the small area include telephone wiring, cable TV cable (optical fiber TV network), power supply wiring, and computer network wiring. These transmission media are the basic transmission media of the community. Among them, the computer network is the focus of the construction of intelligent communities. The network should have very good scalability and scalability, and can provide residents with international Internet access, property management and other services.

In China, the main information dissemination is the telecommunications network and cable TV network. The ways to access the telecommunications network include: digital dedicated lines DDN, ADSL and ISDN, etc., and the actual choice of providing services according to the size of the community and the local telecommunications. The cable television network is also indispensable in residential construction. The cable television network has basically realized the "three wires in one" of image, data and voice. Through a coaxial cable of the cable television integrated information network, intelligence can be realized All the functions of the house. With the development of technology, whether it is connected to an IP phone, WEN terminal or digital TV, it can be realized by plugging in a cable TV socket in the future. Therefore, it is necessary to make full use of the cable TV network to provide intelligent system data communication for the community.

Property management system

Using the network communication system to realize the scientific and standardized management of residential property is an important part of intelligent construction. The property management system mainly includes the following contents:

(1) Three-meter (water, electricity, gas) automatic toll collection system: "Key Points and Technical Guidelines for the Construction of the National Residential District Intelligent System Demonstration Project" requires that smart houses must be equipped with remote meter readings for water, electricity and gas With toll system. The pulse information output by the electronic water meter, electronic gas meter, and electronic electric meter is read by the counter, stored in the E-PROM, and then transmitted to the host of the management center through the network, and the management center calculates the number of pulses and reads the three meter readings to realize remote automatic meter reading At the same time, it is connected to the bank and realizes automatic charging through the bank on a regular basis. It can also provide households with services such as inquiry of online payable fees and collection of arrears through the regional network.

(2) Parking lot management system: generally consists of access card readers, automatic ticket dispensers, door openers, toll booths, vehicle sensors, full-indicator lights and management hosts. The IC card management system is used for automatic charging for the entrance and exit of parking lots. Set up cameras in the out-of-town population to automatically monitor the passing vehicles, and transmit the vehicle data to the management host. The management personnel can browse the entry and exit status of vehicles in each garage and the number of parking in the office. When the vehicle leaves, the IC card held by the driver must be consistent with the computer information in order to lift the rod and release it, ensuring the safe parking of the car.

(3) Community LAN service system: building a community website, residents can get many commonly used information services from the website without Internet access, such as internal electronic mailbox, community announcement notification, weather forecast and other public information query, online library, network Education, online games, software downloads, video on demand, etc., the data transmission rate in the LAN is much faster than that of Internet, and the cost is low.

(4) Community comprehensive information management system: provide query and management on the distribution of buildings in the community, the distribution of public facilities, and the situation of residents in the community, establish a household information database, and realize the computerized management of household file data, making the registration and inquiry of residents simple and fast .

(5) The main equipment monitoring system of the community: The equipment monitoring system performs real-time detection and control of the working conditions of the water supply and drainage, power distribution system and elevators in the community to realize the optimal management of public equipment and reduce the system failure rate. Control the equipment through software to make the equipment operate in the most economical and reasonable mode. When the equipment fails, the management center issues an audible and visual alarm and the on-duty staff informs the maintenance personnel to handle the on-site accident.

(6) Electronic patrol system: set up patrol stations at appropriate locations in the community, and stipulate the patrol route and patrol time of security personnel. When the security personnel arrive at a patrol station, insert the key and push it, the host will get the security personnel Location and time information. The use of electronic patrol management technology can prevent security personnel from missing positions and dereliction of duty, which is an important measure to ensure the safety of the community.

In addition, the community property management system also includes equipment repair, maintenance management, community pipelines, information management, guest access management, community public electromechanical equipment centralized monitoring, equipment operation status information management and regulation; community electronic announcements, background music and other functions.

The residential area will surely develop in the direction of intelligence, which is the general trend and an important part of building a well-off society. The construction of intelligent communities must adhere to the principle of people-oriented, advanced and applicable principles, full consideration of technical feasibility and stability, and full consideration of the actual needs and affordability of residents. Only then can we find a development path for intelligent residential quarters that suits China's national conditions.
