The Design Of Monitoring System Of Air Quality Based On GPRS

Along with the level of life continuously raise, people concern to environment more and more. But the air quality is an important index for influencing environment.The main performance includes the outdoors air the quality, live the air quality of area, the air quality of factory area, and indoor with the air quality of some and particular district.(such as car inside).The air pollution has already become an huge obstacle for development of our country economy and social progressive. The air quality monitoring work is an important means to improves environment quality.Air quality monitoring , which usually involves many things such as temperature,humidity, atmospheric pressure, NO,SO2,CO,TSP,PM10,ect, is an important element of environment monitoring.In this text,an air quality monitoring system based on GPRS is put forward,after we have been analysed the development of the air quality monitoring technical in domestic and international and considered the objective condition of our country. It emphasize on the design of monitoring station and monitoring center.The thesis is mainly divided into 5.In the chapter 1, the development of air quality monitoring and usually monoring and control technical is introduced, and the point research way of data transmission base on the GPRS. In the Chapter 2,the design of the air quality monitoring system is introduced ,which include the main principle of each part of system and the method established of the GPRS, main function and function of each module.In the Chapter 3 ,the design of the terminal's hardware base on GPRS has been introduced ,which include the choice of GPRS modules and the design of outer circuit, the point is design the circuit of the monoring sensor and data processing. In the Chapter 4, the design of the GPRS terminal's communication and software has been introduced, which mainly include the design and realization of the communication protocols. In the Chapter 5, the monitor's center software has been designed and the soft of the position machine and the design of the data-base have been introduced in detail.The monitoring station has been adopted ATmega128 and Q2406A to constitute GPRS data terminal, which mainly include the module of serial communication, data collection and data transmission. The monitoing center has been adopted DEIPHI 7.0 and SQL2000 to desigen, and we mainly have designed communication module basis on SCOKET to realize the data communication with the terminal.In the next step of work, after replanting embedded system-μC/OS,we are going to perfect this modules,so this the system will become more steady.
