Abstract
With the acceleration of the rhythm of people's lives, increasing work pressure, people want more stability and a comfortable life.Life safety of the working environment more and more attention. As the sensor technology, control technology, the continuous development of computer technology, security measures to guard against the high iron gate from the development to the present can not see the wall, the safety factor is several times the original. But the technology is still in development stage, it is also a variety of products, good buckwheat missing. Design a higher factor of safety, and security prices lower system very important.
This article's main task is to design the fire control system, burglar alarm systems and perimeter defense systems and subsystems to achieve the three systems.
By the whole system is divided into an outdoor space, indoor two parts. Selection of active outdoor infrared detectors, active infrared transmitter sent a bouquet of the infrared beam by the modulation, into the infrared receiver to form a cordon. Around the protection system in order to be able to be integrated into the central control system, active infrared detector system access to the PLC by the PLC system will be around the protection system of information transmission to the central control system. Indoor selected JB-R21-SG (1020 / 2 system) linkage-type fire alarm controller, fire alarm and set in one linkage control. Central control system is a computer, using the configuration software, the electronic map display as well as the regional board and collected the information of the subsystems of system integration. When abnormal events occur, the computer control system for the issue of sound and light alarm, and warning instructions on the computer were taking place, such as information, the realization of the intelligent monitoring of the environment.
Key words: security, intrusion alarm, fire alarm, monitoring
