Smart Community, English as Intelligent Residential District. The intellectualization of the building implemented by a relatively independent residential area in a city with a relatively independent area, unified management, and similar characteristics of residential buildings is called Residential Intelligence Residential Intelligence. This community is also called an intelligent community. The smart community is also a product of China's unique national conditions. 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.
The cardinality requirement of intelligent community
The intelligent community includes integrated wiring system, cable television system, telephone exchange system, access control system, building intercom system, monitoring system, anti-theft and networking alarm system, centralized meter reading system, residential energy management system, broadband network access, Parking management system, public address system, property management system, community e-commerce system, etc., a few high-level projects in the smart community, clubs, sports centers also apply the building automation system.
The smart residential unit (Smarthome) in the real-world smart community should be installed with smart home so that the functions of the smart community can be effectively used. For large communities, the smart community is the basic platform for smart home operation. Smart communities are expanded and extended in the basic meaning of intelligent buildings. It provides an investment that is reasonable and has high efficiency, comfort, warmth, convenience, and safety in living environment by optimizing the four basic elements (structure, system, service, management, and intrinsic connection between them) of the community buildings. .
Based on advanced computer technology, communication technology, control technology and IC card technology, adopt a system integration method to gradually establish a multimedia integrated interactive system that communicates residential households and households, households and residential community service centers, households and external communities. Provide residents with a safe, comfortable, convenient, energy-saving and efficient living environment. According to the "Ministry of Construction" outline of the National Residential Community Intelligent Technology Demonstration Project, the intelligent buildings are divided into three levels: the popular residential community, the advanced residential community and the residential community.
Among them, six intelligent requirements should be fulfilled: (1) a computerized automated management center for residential quarters; (2) automatic metering and charging of water, electricity, and gas, and residential quarters; and (3) automatic monitoring and management of security systems; 4) Fire alarms and harmful gas leaks in residential buildings are automatically alarmed; (5) Residential emergency call systems are set up; (6) Centralized management of key equipment and facilities in residential quarters and remote monitoring of their operating status. At the same time, according to the provisions 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 crime warning; (2) Closed-circuit television monitoring; (3) Intercom and Anti-theft door control; (4) Household alarm; (5) Patrol management; (6) Monitoring of security system; (7) Remote copying or IC card management; (8) Vehicle access and parking management; (9) Power supply Equipment, public lighting, elevators, water supply and other major equipment monitoring and management; (10) emergency broadcasting and background music system; (11) property management computer system.
Video intercom access control system technology
The video intercom access control system provides a two-way video call between a visitor and a resident, and can be controlled by a resident to remotely control the opening and closing of the security door and a security system capable of performing an emergency alarm to the cell security center.
1. The function of the video intercom access control system
(1) In addition to the intercom function, the building's visual intercom access control also adds visual functions and better security.
(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 of 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.
Frontline: Modern Intelligent Community Management
Without the intelligent management of high-quality residential quarters, the effects of residential quarters cannot be fully utilized. To truly realize scientific and efficient management, there must be advanced intelligent systems, complete equipment, and unified management, so that they can be called intelligent communities. . 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.
Of course, there are still many problems in the current intelligentization of information technology
1, anti-theft system settings
The term “security†has always been highly valued by people and cannot be taken lightly. Various types of anti-theft facilities in intelligent communities are particularly important. There must be a series of integrated security systems. Their functions include burglar alarm and home security. Using standard sensor signal interfaces, Answering most of the book anti-theft products on the market, the system received a security room, you can also send out alarm information, sparking lights, telephone remote alarm and so on.
The modern community occupies a large area, with a total length of more than one kilometer around it. Traditionally, the perimeter of the community is guarded against high walls and patrols. The current method is too backward. When coupled with weather issues, environmental factors, and other environmental factors, it is easy to form a security corner. 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. Perfect lighting control system
Intelligent function can be exerted in the lighting system. All lights in the plot can be adjusted for brightness. 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 and the street lights are brighter. At one point, there are corridor lights and staircase lights installed with voice-activated sensors. When someone walks by, the sound lights will naturally light up. This will make it possible to use resources better and less wasteful, and it will reduce the burden on owners. This is really a source of energy conservation.
3, building equipment automatic control system processing
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, the 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, they can immediately notify the staff. The staff can be vigilant and the control center can be activated or automatically turned on. Regional and intermittent broadcasts are formed by closing part of the broadcast equipment within the cell. The broadcasting system received a background signal of different accidents and transferred to a pre-recorded accident automatic broadcast or artificial accident broadcast.
5, community pipeline system
The lower pipeline is an important infrastructure of the community. It is accurate, complete or not, and 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 an important means of transport in modern society. People's living standards have improved. Private ownership of modern residential vehicles has become commonplace. Parking management has become more and more irresistible. 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, home 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 homes. However, there are also some problems. The system is too numerous to bring troubles to use and maintenance. There are many outdoor wirings, installation costs and equipment costs are high, and households have many economic burdens. 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:
surveillance system
The usefulness of the monitoring system is very large. It can assist the security system to do real-time monitoring of the environment inside and outside the community as well as the significant areas of the community. 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.
Access Control Authentication System
At the entrances and exits in the first place of the community, intelligent access control security systems are installed on the entrances to the first building. Even at the entrances and exits of the vehicles, a management system capable of discriminating access to vehicles is installed. 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.
Video intercom system
This system is not only a must-have setting for the community, but also uses a more extensive system. 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
The patrol management system is the use of dynamic real-time patrol system technology information for community patrol computer management. The patrol circuit is upgraded to dozens of patrol routes through computer upgrades according to the circumstance of each patrolling point in the community, actual routes, and distance. Stored 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 home security system
Window magnetic, magnetic switch, gas leak alarm, smoke alarm, emergency button and other security systems are used in the home, in each homeowner home installed infrared probes, window magnetic switch, smoke detector, emergency alarm button, etc. Each unit entrance is set up with a host computer at the entrance, 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.
