The so-called intelligent residential district refers to a new type of residential district, which is based on comprehensive wiring, manages and automates all kinds of equipment in the residential district by using computer network through the comprehensive configuration of various functional subsystems in the residential district. Usually, intelligent buildings are "triple A" systems, and it is generally believed that intelligent residential quarters are also "triple A" systems. They are:
(1) SAS- safety automation system
Including indoor burglar alarm system, fire alarm system, emergency help system, population control system, burglar intercom system, gas leakage alarm system, outdoor closed-circuit television camera monitoring system and outdoor patrol sign-in system.
(2) Communication Automation (CAS- Communication Automation System)
Include digital information network, language and fax functions, cable TV and public antenna system.
(3) Management Automation (MAS- Management Automation System)
Including water, electricity and gas remote meter reading system, parking lot management system, water supply and power supply equipment management system and public information display system.
1, the composition of intelligent system in residential quarters
1. 1 safety automation system
Safety automation system can be divided into indoor part and outdoor part according to space.
1. 1. 1 indoor part
All information such as indoor infrared probe, emergency rescue, gas leakage and door magnetic system are connected to the indoor anti-theft intelligent control host. The upper computer is responsible for data collection and analysis, and sends the analysis results to the control center for processing by the computer in the control center. Display and print the information, and notify the personnel on duty and 1 10 alarm center; The functions of each part are as follows:
Infrared burglar detector infrared detectors are installed at every entrance and window of residents' rooms. When someone illegally enters, the infrared detector triggers an alarm, sends a signal to the indoor anti-theft host and sends out an acousto-optic signal. The host sends this signal to the community control center, and the electronic map of the control center shows which building it is. What kind of alarm occurs in which household and room, the personnel on duty can dispatch the nearest security personnel to inquire and handle it on the spot.
Gas leakage alarm and automatic door closing system: the kitchen and bathroom are equipped with gas leakage alarms respectively, which will trigger the alarm once there is gas leakage; On the one hand, automatically cut off the gas source, on the other hand, notify the central control room, which will be handled by the above-mentioned control room attendant.
Fire alarm system. Install a sense of smoke or temperature in the living room. When residents have a fire, it will trigger an alarm and send the signal to the alarm center.
Emergency rescue system. When there is an emergency at home, such as being seriously ill, a thief breaks in and needs help. Press panic button, and the home host will send the signal to the control center. After receiving the report, the duty officer will send someone to the scene to deal with it.
Door magnetic system. A pair of door magnets are installed in the center of the door frame. When someone opens the door illegally, it will give an alarm and the host will transmit the signal to the control center.
1. 1.2 outdoor part
The outdoor part is divided into the following systems:
Community camera monitoring system. There are surveillance cameras at entrances and exits of residential quarters, main intersections, green belts along fences and underground parking lots. The personnel on duty in the control center monitor the camera images for 24 hours, which can be recorded and saved for 24 hours to provide criminal evidence.
Peripheral infrared radiation alarm system. Perimeter infrared cross fire alarm system is set in the fence section. When someone illegally crosses the hurdle, it will call the police and trigger the tracking record of the perimeter camera.
Security patrol sign-in system. Set patrol sign-in devices at the corresponding positions in the community to specify the patrol route and time of security personnel. Security personnel patrol with check-in equipment, and the electronic map of the control center will show the positions of all security personnel (with check-in equipment). When the security personnel do not patrol the designated place within the specified time, the control center will send out an audible and visual alarm signal, and the center can query its location and contact the security intercom system.
1.2 communication automation system
1.2. 1 Use telecommunication network as transmission network.
The communication automation system relies on the construction of external network, such as the comprehensive building of the special development community, and the post office has a commercial network with direct optical fiber connection. The transmission speed is fast. The transmission effect is good, and it can provide ISDN services (integrated service digital network), that is, integrated service data network. It has four characteristics:
This is a communication network based on IDN.
It supports end-to-end digital connection;
It supports telephone and non-telephone communication services;
It provides a standard user network interface.
Its biggest advantage is that it can provide users with telephone, fax, data and conference TV services at the same time on a pair of ordinary telephone lines, and it is fast to pick up people. Can connect the Internet and video links at a high speed of 128KBPS, and truly surf the Internet. (The maximum speed of ordinary telephone calls is 56KBPS) The home network established with the help of the post and telecommunications service network 1SDN can completely provide the same working conditions as the company environment. If you like working from home, you can connect the home computer network to the office computer network. It is not impossible to become a SOHO- small office family.
By the way, the connection between home computer network and home appliances. I learned from the newspaper a few days ago that Microsoft Corporation of the United States is currently negotiating cooperation plans with several major manufacturers of household appliances in the world, and plans to use Microsoft products to control household appliances by computer. If it comes true, the myth of snail girl will come true in the near future. At that time, the computer system will undertake all the household arrangements for you like a very competent nanny. Such as: wake you up on time, adjust the room temperature, light intensity, shop online, prepare recipes, play music, handle emails, and do sanitation and cleaning. Of course, the use of these advanced things depends on the development of the national economy and the affordability of personal income.
1.2.2 using cable TV network as transmission network
Now all the residents in the community are connected to cable TV. Cable TV Tianwei network is a two-way HFC network, which adopts frequency division and digital compression modulation technology, and can transmit high-speed data in addition to conventional TV signals, realizing the integration of image, data and voice. Every household is equipped with a cable modem. Through personal computer, e-mail transmission, remote network login, real-time stock operation, videophone, fax service, home shopping, remote medical diagnosis, security monitoring, automatic copying and so on.
1.3 management automation system
1.3. 1 community vehicle access management system
The IC card management system is adopted for the access and charging of vehicles in residential areas. Long-term users have monthly cards, and visiting vehicles have temporary IC cards. All IC cards are automatically recharged through card readers.
Set a camera at the population of the community to automatically monitor passing vehicles and transmit vehicle information (license plate number, color, etc.). ) to the management center software. When the vehicle leaves, the driver's IC card must be consistent with the computer data before it can be released.
1.3.2 automatic meter reading system for residential quarters
Now all communities are centralized meter reading, but basically mechanical meters are used. In recent years, electronic water meter, electronic gas meter and electronic electric meter have been developing continuously, and the three-meter remote meter reading system is becoming more and more mature. The pulse information output by the three meters is read by the counter, stored in EPROM, and then transmitted to the control center through the network. The control center counts the number of pulses, reads the readings of three meters and prints them out. Advanced users can connect with banks and deduct fees regularly through the banking system to realize the combination of remote meter reading and automatic deduction.
1.3.3 community equipment management system
Constant pressure water supply system and VVVF elevator are widely used in modern residential quarters. All these provide a prerequisite for realizing the automation of equipment management in residential areas. Through the relevant network, the control center can display the running status of the main equipment in the community, such as water pump, pool water level, elevator, high and low voltage switch, street lamp and so on. And can control the equipment through software, so that the equipment can run in the most economical and reasonable way. When the equipment fails, the control center sends out an audible and visual alarm and informs the management personnel to handle the accident.
Several ways to realize the intelligence of two residential quarters
2. 1 cell bus system
First, establish the regional network of the community, connect the subsystems, and then connect the regional network with the public network. In this way, it is necessary to fully consider the needs of each subsystem, make full use of the bus resources of the system, and incorporate the transmission of data communication, intercom, call, alarm, equipment management and other signals into the bus. Try to reduce the wiring in the community and save investment.
2.2 the use of cable TV network
At present, the development of domestic cable TV network is becoming more and more perfect, and the "three-in-one" of image, data and voice has basically been realized. Through a coaxial cable of CATV integrated information network, all the functions of intelligent community can be realized, and this network has great development space. For example, IP phones, network terminals, and digital TVs are very fashionable abroad at present, as long as they are plugged into cable TV sockets. It can be seen that in the development of information industry, CATV will be the most powerful competitor of telecommunication network.
2.3 the use of telecommunications networks
Its implementation method is basically the same as cable TV network, which has been mentioned before and will not be described here.
3 Conclusion
At present, the intellectualization of residential quarters is in its infancy, lacking national unified standards and norms; Secondly, the intelligent construction of residential quarters depends on the development of national economy and the improvement of the overall quality of the people. Once these systems are perfect, users can use them conveniently and quickly, and people are willing to spend money and get value for money. On the other hand, to realize the intelligentization of residential quarters, we need the support of government departments and make unified plans.
