The intellectualization of buildings implemented in a relatively independent area, a residential district composed of unified residential buildings and buildings with similar characteristics and management features is called community intelligence, and the community is also called an intelligent community. The smart community is also a product of China's unique national conditions. 
Access control intercom and security dual line operation and maintenance technology
The main difference between smart communities and smart buildings in public buildings is that the smart community emphasizes individual residential units and focuses on property management functions.
According to the "Ministry of Construction" of the "National Residential Community Intelligent Technology Demonstration Project" stipulations, the intelligent building is divided into three levels: the popular residential community, the advanced residential community and the leading residential community.
Among them, six intelligent requirements should be implemented:
(1) The establishment of a computer automation management center in a residential area;
(2) Automatic measurement and charging of water, electricity, gas, etc., closed residential quarters;
(3) Implement security monitoring system automation monitoring and management;
(4) Automatic fire alarm and harmful gas leakage in the house;
(5) Residential emergency call system;
(6) Centralized management of key equipment and facilities in residential communities and remote monitoring of their operating status.
At the same time, according to the regulations of the Housing Industry Promotion Center of the Ministry of Construction, the model community should have the following functions in terms of safety precautions and information management:
(1) Exit and entrance management and perimeter security alarms;
(2) CCTV monitoring;
(3) Intercom and security door control;
(4) Household alarm;
(5) patrol management;
(6) Monitor the security system;
(7) Remote copying or IC card management;
(8) Vehicle access and parking management;
(9) Monitoring and management of major equipment such as power supply equipment, public lighting, elevators, and water supply;
(10) Emergency broadcasting and background music systems;
(11) Property Management Computer System.
Intercom Access Control System Technical <br> <br> video intercom access control system implemented between tenants and guests visiting bidirectional video call, and can be remotely controlled by the security door switch to a cell capable of households and security center A security system for emergency alarms.
1. The function of the video intercom access control system (1) In addition to the intercom function, the building visual intercom access control also increases the visual function and has better security protection.
(2) When there is a guest, press the corresponding panel number of the host panel, the user machine will send a ringing tone, at the same time automatically open the display of the visitor image, after the machine and the guest to talk and confirm the identity, you can remote control the door through the user's unlock key Control door lock unlock.
(3) After the guest enters the door, the door closer automatically closes and locks the door.
(4) If the occupant needs to monitor the situation outside the gate, press the monitor button to display it on the screen and close it automatically after about 10 seconds. 
2. Design scheme for video intercom access control system This system is a bus-based digital two-way intercom one-way visual access control system. Bus-based 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 implement two-way calling with the management center and Loudong host. Through the video intercom system, the residents and the residential property management center have established an internal communication channel.
Each door-to-door system of the system accesses the management machine through the Internet to realize resource sharing. Through networked lines, visitors can call the management center directly at the door machine. The management center can display the building's number of the call and make calls, make inquiries or handle incidents.
Each unit door uses a unit Chinese network video intercom door machine. The door machine Chinese liquid crystal display, all-digital programming, and installation of low-light black and white camera, infrared compensation at night, the indoor unit can be clearly observed in a dimly lit environment.
The visitor prompts the user to call the home through the door machine. The visitor's indoor extension can display the visitor's image. After conducting a two-way conversation with the visitor and confirming the identity of the visitor, the electronic lock of the security door downstairs can be opened remotely and the visitor enters. This system also has a password opening function. If the password is pressed three times in a row, the system will automatically transfer to the administrator host to remind the administrator to pay attention.
Because it is a full digital two-way intercom one-way vision system, it has strong system functions, such as indoor alarm for occupants, resident call management center, call confidentiality, call restriction, and open access control.
Line: modern intelligent community management <br> <br> not high quality residential quarters intelligent management, not only can give full play residential quarters effect, to realize scientific and efficient management, there should be advanced intelligent systems, equipped Only integrated management can be called an intelligent community. In fact, we can not only have a good system, but also have professional management personnel, so that the two will have high-quality intelligent community.
At present, there are still many problems in the intelligentization of information technologies that have not been completely universalized.
1. The word "security" has been set up in the anti-theft system. People are very concerned about it and cannot be taken lightly. Various anti-theft facilities in the intelligent community are particularly important. There must be a series of integrated security systems. Their functions include anti-theft alarm and home security. Sensor signal interface, can be connected to the market most of the books anti-theft products, the system received a security room, you can also send out alarm information, sparking lighting, telephone remote alarm.
The intelligent defense method is used to install the perimeter prevention system, use active infrared technology, and create an electronic curtain wall on the borders of the community. It can monitor the surrounding conditions of the community 24 hours a day, in all directions, and achieve all things lost. It is highly concealed and is not easily found by intruders.
The peripheral guard system infrared receiver receives the cell security center alarm receiver. When someone illegally crosses, cutting off the infrared road will trigger an alarm. Combined with the CCTV system, the alarm position and the cause of the alarm can be displayed immediately, which can reduce time and manpower.
Closed-circuit television systems are also very important. Closed-circuit television systems are the most direct security system for providing real-time visual images for security centres.
You can observe the flow of personnel at entrances and exits, public places such as stations, and 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 in the control room of the community, providing remote visual effects for the security system, and providing monitoring channels for various personnel activities in the community.
Closed-circuit television monitoring system mainly installs channels, important construction and peripheral settings, and transfers the images to the management center. The management center conducts real-time monitoring and recording of the entire community so that the center administrator can fully understand the dynamics of the community.
2. The lighting control system can improve the intelligent function in the lighting system. All the lights in the plot can be used for brightness adjustment. To meet the needs of different parties in the plot, the lighting will be adjusted in different situations, for example: the garden lights Can be darker, street lights are brighter, there are corridor lights and staircase lights installed with voice-activated sensors. When someone walks past, the sound lights will naturally light up. This will allow better use of resources and less waste, and it will reduce the burden on owners. There are many sources of festivals.
3. The automatic control system for building equipment In today's world, energy conservation and environmental protection are common trends in the world. The information acquisition and automatic control were carried out in the community. All information collection and automatic control were automatically completed by public equipment management systems relying on computers, which played centralized management, decentralized control, and reduced energy consumption.
The working status of all electromechanical equipments in the community can be monitored by the central control system room of the community. Any abnormal conditions can be quickly discovered and quickly resolved to ensure that the equipment is always operating in the best condition and the equipment usage rate and service life are improved. At the same time, it can also greatly reduce the operation and maintenance personnel and reduce the manpower cost of property management. 
4. Public Broadcasting System Under normal circumstances, this system can automatically broadcast cable broadcasts and background music according to the programmed time. The broadcaster can insert speeches at any time. In the event of an emergency, he can immediately notify the staff. The staff can increase vigilance. The control center can Move or automatically turn on and off some of the broadcast devices in the cell to form a regional or interval broadcast. The broadcasting system received a background signal of different accidents and transferred to a pre-recorded accident automatic broadcast or artificial accident broadcast.
5. The pipeline under the district pipeline system is an important infrastructure for the community. It is accurate, complete or not, and it directly affects the planning, construction, maintenance and management of the community. In the past, the information of the pipelines under the community was incomplete, the deviation was too large, and the management methods were obsolete, which led to the backwardness of maintenance and management. The construction of a scientific, accurate, complete and dynamic integrated pipeline information system has enabled the digitization of various types of pipelines in residential communities and created favorable conditions for residential property management and system maintenance.
6. Parking Management System Motor vehicles are important means of transportation in modern society. People's living standards have improved. It is common for privately owned vehicles to have modern residences. Parking management is becoming more and more unavoidable as a problem for community managers. Using an intelligent system can easily solve this problem.
The community vehicles are divided and managed according to different factors such as time, sequence, internal and external units, and prices, which provides convenient parking for parking facilities and vehicle safety, and also makes the management of community vehicles more complete. The smart community generally includes shopping malls, entertainment and other ancillary facilities in a modern, integrated residential community. The parking lot convention system has a toll booth and is networked with the control center. All front-end equipment is cabled to the toll hall to centralize control and operations.
7. Family Intelligence Many three-meter remote systems, video intercom systems, and anti-theft alarm systems have been installed in many built or newly-built residential homes. These systems have undoubtedly improved the safety and comfort of the home. However, there are also some problems. The system is too numerous, which causes great troubles for use and maintenance. There are many outdoor wirings, and the installation cost and equipment cost are relatively high. Households are a lot of economic burden.
Understand the intelligent solution, using the "home intelligent controller" method for each household, to achieve intelligent household household management. It can handle a variety of sensing signals, make appropriate processing, and has networking capabilities. The home controller network is connected to the cell management center to implement the cell management center for the security monitoring of each household.
The smart community is currently a relatively new concept in China. To achieve maximum functionality and reduce costs, modernization must be implemented. Advanced technology is used to bring together disparate systems and equipment in the past, and several systems are closely integrated with each other and rely on each other instead of one. Solitary system, unified overall, can play a greater role.
Use technical means to reduce personnel, reduce management costs, meet the maximum comfort of the occupants, and minimize the economic burden on the occupants. This can be a truly modern smart community.
Second line: Comprehensive use of intelligent community security system
Nowadays, new residential quarters are generally equipped with security systems and property management personnel to ensure the safe life of residential residents. In particular, the use of residential security systems makes residents feel more secure.
Community security system mainly includes the following aspects: monitoring burglar alarm, access control security system, video intercom system, electronic patrol system, and gas leak alarm, smoke alarm, emergency and other comprehensive use of the system. The community security center is responsible for centralized monitoring and management of various subsystems of security. Below we highlight five of these systems:
<br> <br> monitoring system monitoring system use is very large, it can assist the security system inside and outside the district for the environment, and community dignitaries area do live real-time monitoring. When an alarm occurs in the security system, it will activate the camera in linkage and switch the area screen monitored by the alarm point to the main monitor, and at the same time run the recorder to record the live scene. This system is also one of the mandatory systems for smart communities.
<br> <br> access authentication system in a first cell entrance, entrance of the building and the first, there are installed a smart access control security systems, even in the vehicle to the entrance, can identify a vehicle need to install a management system access. When a person enters or exits from a community, when the vehicle enters or exits, it is necessary to use the access control card of the community. After the card reader has been authenticated, it is allowed to enter or exit.
Each access control card has been registered and authorized in the security center. When the owner inadvertently loses the card, it must immediately notify the security center and report the loss, and replace the new card in time. All readers in the community are networked through the field control bus and security center, which can accurately record the first time of entry and exit of the first cardholder.
When any device in the system detects the use of a loss-sensing card, the system will automatically warn the security personnel to handle it.
The video intercom system <br> <br> cell system is not only required settings, and the system is more widely used. When the owner has the guest to visit, just press the corresponding room number, the owner can see the visitor's appearance through the home video intercom terminal, and open the access control to the guest.
The residential property management department and households, households and households can use the system to communicate with each other. If the property department notifies the household to pay various fees, the household notifies the property management department to perform maintenance on the residential facilities, and the households in the emergency to the community security personnel. Or neighbors call for help. This system is one of the smart community's most important systems.
Patrol Management System <br> <br> Patrol management system is always dynamic real-time inspection system using information technology management computer Patrol cell, a cell according to the situation of each line patrol patrol point VIP extent, actual route, distance, etc., through the computer Upgraded into dozens of patrol routes and saved in the Patrol Management Computer Database.
There are a number of patrolling points on each patrol route. The patrolling point uses a card reader to get the patrol personnel to each patrol time. The patrol point movements and other data are recorded in the system and passed through the security center. The inspection of the patrol records will enable the assessment of the patrol quality, so that the inspection vouchers can be supplied to the patrolling staff.
This system is not a mandatory system in the community at present, but high intelligence has been equipped with this system.
Integrated security system <br> <br> magnetic window in the home, door switches, gas leak alarms, smoke alarms, emergency buttons are used in security systems within the family, the installation of an infrared sensor in every owner's home, window magnetic door Magnetic switches, smoke detectors, emergency alarm buttons, etc. Each entrance to the unit is equipped with a doorway host, and a set of management hosts is set up in the security center.
When a guest visits, press the outdoor button or the room number of the respondent, and the room indoor unit will send a ringing tone. At the same time, the indoor unit screen will automatically open, showing the visitor’s image and outdoor conditions, and the host and guest intercom call. After confirming the identity, the remote control gate electric lock can be accessed by the indoor extension unlocking key. After the guest enters the gate, the gate is automatically closed.
The home security system can be located around the public area of ​​the community to prevent, security monitoring, patrol management and video intercom electronic integration combined with a comprehensive intelligent security system.
Home security system includes: magnetic switch, infrared detectors, gas detectors, smoke detectors, emergency alarm buttons, each household can be set up a home alarm controller, the door magnetic, infrared detectors, gas detectors, smoke detectors When different probes receive different zones, they can clearly distinguish which route is the alarm when guaranteeing the alarm.
Access control intercom and security dual line operation and maintenance technology
Inherent technical exchanges a relatively independent urban area, unified management, intelligent building residential quarters feature similar residential buildings consisting of implementation, called the Intelligent Community, the district also known as the Intelligent Community. The smart community is also a product of China's unique national conditions.
