The intelligent building of a residential community consisting of a relatively independent area, a unified management, and a similarly-characterized residential building group is called cell intelligence, and the cell is also called an intelligent community. The smart community is also a product of China's unique national conditions.
Access control intercom and security two-line operation and maintenance technology
The main difference between intelligent communities and intelligent buildings in public buildings is that smart communities emphasize individual residential units and focus on property management functions.
According to the Ministry of Construction's "National Residential Community Intelligent Technology Demonstration Project Construction Outline", the intelligent buildings are divided into three levels: popular residential quarters, advanced residential quarters and leading residential quarters.
Six intelligent requirements should be implemented:
(1) Establish a computer automation management center in the residential community;
(2) Automatic metering and charging of water, electricity, gas, etc., closed residential areas;
(3) Implement automatic monitoring and management of safety prevention systems;
(4) Automatic fire alarms for residential fires and harmful gas leaks;
(5) Residential emergency call system;
(6) Centralized management of key equipment and facilities in residential quarters, and remote monitoring of its operational status.
At the same time, according to the regulations of the Ministry of Construction Housing Industrialization Promotion Center, the demonstration community should have the following functions in terms of security prevention and information management:
(1) Entrance and exit management and perimeter prevention alarms;
(2) CCTV monitoring;
(3) Intercom and anti-theft gating;
(4) Household alarms;
(5) Patrol management;
(6) Implement monitoring of the security system;
(7) Remote copying or IC card management;
(8) Vehicle access and parking management;
(9) Monitoring and management of main equipment such as power supply equipment, public lighting, elevators, and water supply;
(10) Emergency broadcast and background music systems;
(11) Property management computer system.
Video intercom access control system technology
The video intercom access control system provides a two-way visual call between the visitor and the resident, and the resident can remotely control the security door switch and a security defense system capable of performing an emergency alarm to the community security center.
1. Visual intercom access control system function
(1) Building visual intercom door ban has the function of intercom, but also adds visual function and better security.
(2) When there is a visitor, press the corresponding room number of the host panel, the user machine will ring the ringing tone, and automatically display the image of the visitor. After the machine is intercommunicated with the guest and confirmed the identity, the door can be remotely controlled by the unlock button of the user machine. The door lock is unlocked.
(3) After the guest enters the gate, the door closer automatically closes and locks the gate.
(4) If the household needs to monitor the situation outside the gate, press the monitor button to display it on the screen and automatically close after about 10s.
2, visual intercom access control system design
The system is a bus-based all-digital two-way intercom one-way visual access control system. The bus system all-digital two-way intercom one-way video access control system adopts digital coding technology and two-way communication transmission technology. The whole system can communicate in two directions, that is, the indoor extension can alarm to the management center and realize two-way calling with the management center and the building host. Through the visual intercom network system, the residents and the residential property management center establish an internal communication channel.
Each door machine of the system accesses the management machine through the networking line to realize resource sharing. Through the networked line, the visitor can directly call the management center at the door machine. The management center can display the building number of the call and make a call to make an inquiry or handle the event.
Each unit door uses a unit Chinese network video intercom door machine. Chinese LCD display of door machine, full digital programming, and installation of low-light black-and-white camera, with infrared compensation at night, the indoor unit can clearly observe the visitor in dim environment.
The visitor calls the resident through the Chinese language of the door machine, and the image of the visitor can be displayed on the indoor extension of the household. After making a two-way conversation with the visitor and confirming the identity of the visitor, the electronic lock of the security door downstairs can be remotely activated, and the visitor enters. This system also has the function of password opening. If the password is pressed three times in succession, the system will automatically transfer to the administrator host to remind the management personnel.
Because it is an all-digital two-way intercom one-way visual system, it has strong system functions, such as indoor alarm for residents, call management center for residents, confidentiality of calls, limited time for calls, and access control for opening doors.
First line: modern intelligent community management
Without the intelligent management of high-quality residential quarters, it is impossible to give full play to the effect of residential quarters. To truly realize scientific and efficient management, it is necessary to have advanced intelligent systems, improve equipment, and unify integrated management, so that it can be called an intelligent community. . In fact, you can't just have a good system, but also have professional management talents, so that the two will have a high-quality intelligent community.
At present, there are still many problems in the intelligentization of information technology without full popularity.
1, anti-theft system settings
The term "anti-theft" is highly valued by people and cannot be taken lightly. The various anti-theft facilities in the intelligent community are particularly important. There must be a series of integrated security systems. The functions include anti-theft alarm and home security. The standard sensor signal interface can be used. Most of the book anti-theft products on the market are connected. The system is connected to the security room and can also send out alarm messages, triggering flashing lights and remote alarms.
Use intelligent methods to install the perimeter protection system, use active infrared radiation technology, and put an electronic curtain wall on the boundary of the community. It can monitor the surrounding conditions of the community 24 hours a day, so that everything is lost. It is concealed and not easily found by intruders.
The peripheral protection system infrared device receives the community security center alarm receiver. When someone illegally crosses, cutting off the infrared path will trigger an alarm. In combination with the closed-circuit television system, the alarm position and the cause of the alarm can be immediately displayed, thus reducing time and labor.
CCTV systems are also important. The CCTV system is the most direct security system for real-time video images for security centers.
It can monitor the flow of people in public places such as entrances and exits, stations, etc., and can monitor and record various work, production, and living conditions. In the intelligent community, the closed-circuit monitoring system enables the management personnel to observe the scenes of all important places in the community, providing remote visual effects for the security system and providing monitoring channels for various personnel activities in the community.
The closed-circuit television monitoring system mainly installs the passage, important construction and surrounding settings, and transfers the images to the management center. The management center records the entire community in real time, so that the central administrator can fully understand the cell dynamics.
2, lighting control system is perfect
The lighting system can play an intelligent function. All the lights in the cell can be adjusted for brightness. In order to meet the needs of different parties in the community, the lighting will be adjusted according to different scenarios. For example, the garden lights can be darker and the street lights are bright. At one point, there are corridor lights and stair lights to install sound-sensing induction. When someone walks by, the sound light will naturally light up, so that resources can be better utilized, not easy to waste, and the owners can reduce the burden.
3. Building equipment automatic control system processing
In today's world, energy conservation and environmental protection are the general trends in the world. The community has carried out information collection and automatic control. All information collection and automatic control are automatically completed by the public equipment management system relying on the computer, which has played a centralized management, decentralized control, energy saving and consumption reduction.
The working status of all electromechanical equipment in the community can be monitored by the central control system room of the community. Any abnormal situation can be quickly detected, and the best condition for ensuring the equipment always running is solved quickly, and the equipment utilization rate and life span are improved. At the same time, it can greatly reduce the operation and maintenance personnel and reduce the labor cost of property management.
4. Public address system
Under normal circumstances, the system can automatically play cable broadcasts according to the programmed time. Background music, broadcasters can insert and broadcast speech at any time. When there is an emergency, they can immediately notify, the staff can be vigilant, and the control center can be activated or automatically opened. A regional or interval broadcast is formed by turning off some of the broadcast devices in the cell. The broadcasting system receives the background signals of different accidents and transfers them to the automatic broadcast of the accident or the automatic accident broadcast.
5, community pipeline system
The lower pipeline is an important infrastructure of the community. Whether it is accurate or complete, it directly affects the planning, construction, maintenance and management of the community. In the past, the pipeline data in the community was incomplete, the deviation was too large, and the management methods were old, resulting in backward maintenance and management. The construction of scientific, accurate, complete and dynamic comprehensive pipeline information system has realized the digitization of various pipelines in residential quarters, which has created favorable conditions for residential property management and system maintenance.
6, parking lot management system
Motor vehicles are important means of transportation in modern society. People's living standards have improved. Private homes with privately owned vehicles have become commonplace. Parking management is becoming more and more a problem in front of community managers. This problem can be easily solved with an intelligent system.
The community vehicles are managed according to different factors such as time, order, internal and external units, price, etc., providing parking convenience to the parking users, vehicle safety, and making the vehicle management of the community more perfect. The intelligent community generally includes comprehensive modern residential quarters for shopping malls, entertainment and other ancillary facilities. The parking lot convention system has a toll booth and is connected to the control center. All front-end equipment cables are wired to the toll booth for centralized control and operation.
7, family intelligence
Many of the built or new residential homes have installed three-table remote systems, video intercom systems, anti-theft alarm systems, etc. These systems have undoubtedly improved the safety and comfort of the living room. However, there are still some problems, and the system is numerous, which causes great troubles for use and maintenance. There are many outdoor wirings, installation costs and equipment costs are high, and residents have many economic burdens.
In the intelligent solution, each household is set up with a “home smart controller†method to realize intelligent management of households. It can handle a variety of sensing signals, handle them accordingly, and have networking capabilities. The home controller network is connected to the cell management center to implement security monitoring for each household in the cell management center.
At present, the intelligent community is a relatively new concept in China. To maximize the function and reduce the cost, it is necessary to realize modernization. The advanced technology is used to bring together the scattered systems and equipments in the past, and several systems are closely integrated and supported by each other. A solitary system that unites the whole can play a greater role.
Use technical means to reduce personnel, reduce management costs, meet the maximum comfort of residents, and minimize the economic burden of households. This can be a truly modern intelligent community.
Second line: comprehensive use of intelligent community security system
Nowadays, new residential quarters are usually equipped with security systems and property management personnel to ensure the safe living of the residents. In particular, the use of community security systems has made community residents feel much safer.
The community security system mainly includes the following aspects: monitoring burglar alarm, access security system, video intercom system, electronic patrol system, and gas leakage alarm, smoke alarm, emergency help and other systems. The community security center is responsible for centralized monitoring and management of security subsystems. Below we highlight five of these systems:
surveillance system
The monitoring system is very useful, and it can assist the security system to perform on-site real-time monitoring of the environment inside and outside the community and the area of ​​the community. When the security system has an alarm, it will open the camera and switch the screen of the monitored area of ​​the alarm point to the main monitor, and run the recorder to record the live scene. This system is also one of the mandatory systems for smart communities.
Access control identification system
At the first entrance and exit of the community, the intelligent access control security system is installed at the entrance to the first building, and even at the vehicle entrance and exit, a management system capable of identifying the vehicle access is required. When a person enters or leaves the community, when the vehicle enters and exits, the access control card of the cell needs to be used, and the card reader can be allowed to enter and exit after the identification is valid.
Each access control card has been registered and authorized in the security center. When the holder accidentally loses the card, he/she must immediately notify the security center and report the loss, and replace the new card in time. All the card readers in the community are connected through the on-site control bus and the security center, which can accurately record the first time of the first cardholders.
When any device in the system finds a loss sensor card, the system will automatically alarm to remind security personnel to handle it.
Video intercom system
The system is not only a mandatory setting for the community, but also a relatively extensive system. When the owner has a guest to visit, simply press the corresponding room number, the owner can see the appearance of the visitor through the video intercom terminal at home, and open the door to the guest.
The property management department of the community and the households, households and households can use the system to talk to each other. If the property department informs the tenants to pay various fees, the tenants inform the property management department to repair the residential facilities, and the residents give the community security personnel in an emergency. Or neighborhood alarm for help. This system is one of the intelligent cell saliency systems.
Patrol management system
The patrol management system uses the technical information of the dynamic real-time patrol system to conduct cell patrol computer management. The patrol line is combined into dozens of patrol routes according to the degree of patrol points, actual routes, distances, etc. of the patrols. Saved in the Patrol Management Computer database.
There are a number of patrol points on each patrol route. The patrol point uses a card reader, and the patrol personnel arrive at each patrol point time. The patrol point action and other data are recorded in the system, and passed through the security center. Checking the patrol record can assess the quality of the patrol, so that the patrol personnel can supply the assessment vouchers.
This system is currently not a mandatory system for the community, but it is equipped with this system with a high degree of intelligence.
Integrated security system in the home
Window magnet, door magnetic switch, gas leak alarm, smoke alarm, emergency button and other security systems are used inside the home. In each home owner's home is equipped with infrared probe, window magnetic door magnetic switch, smoke detector, emergency alarm button, etc. Each door entrance is provided with a door host, and a management host is set in the security center.
When a guest visits, press the outdoor button or the respondent's room number, the indoor room will ring the ringing tone, and the indoor unit display will automatically open, showing the visitor's image and outdoor situation, the host and the guest intercom, After confirming the identity, you can use the indoor extension unlock button to remotely control the door electronic lock to allow the guest to enter. After the guest enters the gate, the gate will automatically close.
The home security system can be integrated with the public part of the community, security monitoring, patrol management and video intercom electronic integration combined with a comprehensive intelligent security system.
Home security system includes: magnetic switch, infrared detector, gas detector, smoke detector, emergency alarm button, each household can set an alarm controller, magnetic door, infrared detector, gas detector, smoke detector When different probes are connected to different zones, it is possible to clearly distinguish which way to alarm when the alarm is guaranteed.
