Abstract :
Communications center monitor & control system, including power supply sub-system, environment sub-system, fire sub-system, security sub-system and so on, is widely used in school, enterprise, government and other areas. The control system designed by this paper can get temperature and humidity information from RS485 sensor of temperature-humidity. From measuring gate sensor, smoke sensor and leak-water senor, the control system can get the alarm information. LCD displayer is designed in the system to display the above information. The threshold value of temperature can be set by keyboard in the system. When real temperature is more than the threshold value, the system can control electric fan to run to cool the air. When the alarm accident happens, it alarms with sound and light.
