Noise monitoring system based on ZigBee wireless communication

The utility model provides a noise monitoring system based on ZigBee wireless communication. Sub stations are connected with a noise sensor and processing module, a CF card, a button, a display screen, other analog quantities and a center station, wherein the noise sensor and processing module is connected with the sub stations through an RS232 serial port line, other analog quantities are connected with the sub stations through A/D conversion, and the sub stations are connected with the center station through a ZigBee transmission module. The noise monitoring system based on ZigBee/GPRS wireless communication can be used at any place and can realize motion monitoring even on a moving transportation tool; through remote wireless communication, the monitoring center and each monitoring sub station are constantly in a real-time online connection state, and data of each sub station is automatically transmitted to the monitoring center within prescribed time; the noise monitoring system can be deployed at city areas in a whole city and is suitable for monitoring a pollution state in a relatively large scope.
