Application of Security System in Intelligent Residential Area

With the continuous development of the information age, the construction of intelligent residential communities has been continuously improved. From the early single independent systems of television, telephone, broadband, closed-circuit television monitoring, etc., has developed to a higher stage. With the rapid advancement of computer (including hardware, software and networks, etc.) technologies, communication technologies, and control technologies, various high-tech products have been widely used in residential areas. The Housing Industry Promotion Center of the Ministry of Construction has proposed a basic concept for intelligent communities: “The intelligentization of residential communities is the use of 4C (ie, computers, communications and networks, self-control and IC cards), and will provide diverse information services through effective transmission networks. Integrate with management, property management and security, and house intelligence to provide high-tech and intelligent means for the residential community's services and management, in order to achieve fast and efficient premium services and management, and provide a safe and comfortable home environment.” With the continuous advancement of new products, new technologies and new processes, this basic concept will also change.

1. Basic elements of intelligent residential community construction

The construction of intelligent residential quarters should be based on the overall planning of community development and follow the following basic elements.

1.1 Correct understanding of intelligent community

First of all, for the construction of an intelligent residential community, the constructor must clarify what an intelligent community is. It is not just a television outlet, but a surveillance camera. The intelligent community is a comprehensive multi-technical system engineering. It not only requires the application of professional technology, but also requires the cooperation of other professionals. The correct understanding plays a crucial role in the subsequent operation of the community.

1.2 Rational demand for intelligent community

The construction of an intelligent residential community requires a reasonable demand positioning. The level of intelligent building of the community must be determined according to various factors such as the project investment of the community, overall planning, sales targets, construction of supporting facilities, surrounding environment, and follow-up management. Demand analysis includes user demand, community management needs, market affordability needs, and future social development needs. For example, if the construction side of the residential area is a high-end residential building, and equipped with standard intelligent systems such as TV and telephone broadband, it should also consider the provision of high-end smart cards, smart home systems, etc. to improve the quality of residential buildings. Based on the above factors, we can determine the implementation of the next step.

1.3 System Optimization Design for Intelligent Community

The key to the construction of an intelligent community lies in the overall planning and design of the system. Whether or not a community can truly reflect its intelligence is entirely due to this. Intelligent construction is a systematic project. It is composed of various subsystems. In the implementation and operation stage of each system, they are a whole. In the design, we must pay attention to the various aspects of the system's applicability, energy efficiency, scalability, economy and other factors, but also to consider the connection between the various systems, optimize the design, so that it achieves the purpose of safety and comfort.

1.4 Standardized Implementation of Intelligent Community
After clarifying the purpose of construction, it will enter a real implementation stage. Standardized implementation will ensure the smooth operation of intelligent system engineering. From the author: Tsinghua University system planning, proposals, design to detailed design and then the construction, installation, commissioning, and ultimately to the stable operation of the system, the whole process needs to implement its standardized operation. The standardized implementation provides guarantees for investors, builders, constructors, and users, enabling the intelligent construction of communities to proceed in an orderly manner, and is the foundation of intelligent community system operation.

2. System planning of intelligent residential community

The construction of intelligent residential system projects in the residential community is based on integrated wiring and integrates the various subsystems efficiently and stably.

2.1 Security Automation 2.1.1 CCTV Monitoring System

The closed-circuit television monitoring system in the community includes indoor and outdoor parts. The areas that need to be protected in the room may include the front room of the elevator, the elevator, the entrance to the rooftop, the access opening to the underground garage, and the underground parking lot; the outdoor protection area may include the entrance and exit of the community, the surrounding area of ​​the community, and the residential area. Within the main street and other hidden locations. The camera adopts the deployment mode of common camera and infrared camera, fixed-point camera and moving-point camera, and can adopt full-time real-time recording to ensure the safety of the community.

2.1.2 Anti-theft alarm system

In the indoor room, Shuangjian detectors, alarm buttons, and magnetic sensors are installed. When an alarm occurs, the signal is transmitted to the cell control center. The on-duty personnel of the cell control center can immediately rush to the scene for processing. Shuangjian detectors can be set up in some important rooms. The alarm buttons are set in places that are hidden and convenient for people to use.

2.1.3 perimeter prevention system

In order to prevent lawbreakers from illegally entering the community, an infrared radiation probe is designed to be installed on the wall or fence of the community. It can provide a safe first-line defense for the community. This system can be linked with the closed-circuit television monitoring subsystem. For ease of management, the system can be configured with alarm management software that contains an electronic map that visually displays the alarm area.

2.1.4 Patrol System

A wireless patrol system is set up in the community, and personnel on duty in the community can hold patrol sticks, perform patrols according to a certain route, and then upload the patrol records to the management machine. This is a combination of man-machine protection, and the planning of the patrol route is very important.

2.1.5 Smart Home System

With the continuous development of community intelligence, smart home systems have been used in residential areas. Smart home systems based on video intercom systems have gradually become accepted by people. The on-site and remote control of lights, curtains, and household appliances is achieved through equipment, which is an integral part of the modern intelligent community building.

2.1.6 Access Control System

Access control systems can be set up at all entrances and exits in the community, using a single card format, and using an IC card to allow residents and property management personnel within the community convenient, fast and safe access.

2.1.7 Gas Leakage Alarm System

Gas leakage alarm system is installed in the kitchen, restaurant and other locations installed gas leak alarm, once there is a gas leak, that triggers an alarm; on the one hand, it automatically cut off the gas supply, on the other hand to inform the central control room by the control room attendant for processing.
