Status quo of security technology application in smart communities

At present, there are more than 1,000 smart cities that have been launched or under construction in the world. There are more than 300 cities in China that propose smart city planning, and there are more than 500 pilot cities of various types. The community is an integral part of the city and covers urban residents. The last mile of everyday life. With the wisdom of the city and the deepening of data, the “smart community” has become an important “cell” of urban construction, and it is the epitome of the “smart city” at the micro level of the city. The degree of intelligence of the community determines the intelligent ceiling of the city. .

Safety needs are the basic needs of people. As a place where residents live, safety has always been the top priority of community building. Safety has also become one of the important factors for residents to choose a community. Security technology has been used in the community for many years. With the development of smart communities, the community security prevention construction model combining “human defense + technical defense” has become the “standard action” for community construction and operation. More advanced communities usually build Including video surveillance, intrusion alarm, parking management, access control, visitor management, attendance consumption, elevator control, online inspection, fire alarm and other subsystems of the integrated security system.

Among them, the video surveillance subsystem in the cell entrances and exits, outdoor intersections, perimeters, basements and other regional channels to achieve "people over the shadow, car over the mark", while the community's key parts of the implementation of all-weather, 24-hour monitoring to achieve community Security management.

The intrusion alarm subsystem mainly guards against the border areas where the security is weak and the outsiders invade the community. For example, an active infrared beam is placed on the fence for all-weather work, and an outsider is detected to immediately report an alarm. The alarm point detector generates an alarm signal and outputs it to the alarm host. The alarm host transmits the alarm information to the alarm server through the network. The security personnel can immediately see the alarm pop-up in the system of the monitoring room, and the security personnel take over the alarm.

The parking lot management subsystem realizes the management of vehicle entry and exit and parking of the community by deploying vehicle gates at the entrances and exits of the community and the entrance and exit of the underground parking lot. When the internal community car approaches the parking lot exit, or detects the arrival of the vehicle through the vehicle detection coil located under the lane, the exit remote card reader is activated, and the card reader performs double authentication judgment on the long-distance electronic tag; or through video The license plate is identified, and after the comparison, the instruction to release or refuse to lift the bar is performed. The system can store images, license plate numbers, entry and exit time and other data in the database. Each record corresponds to the image of the vehicle. Property management can be called at any time, and the vehicle entry and exit strategy can be managed in the system.

The access control subsystem uses the cell network system to set access control devices so that only authorized smart card users can access the access control. The access control management subsystem is generally a network management mode for central management control and authorization, and access control remote switch gates. Usually, the access control equipment of each community building can be managed in the monitoring center.

Security system is an important part of the smart community. In the current smart community, security prevention, in addition to the construction of various subsystems, also pays more attention to overall linkage and intelligence. Linkage is not only reflected in the centralized management, early warning linkage and strategic allocation of the back-end by a platform, but also in the information collaboration and linkage of residents, property and other parties; wisdom refers to more and more communities. It has begun to dig deeper into the data generated by daily security systems, making full use of advanced technologies such as big data and artificial intelligence to carry out applications such as risk analysis, event prevention, and personalized services. In this way, we can provide a warm, safe and convenient modern and intelligent living environment for the community residents and realize the ultimate goal of the smart community.
