Abstract


Continuous Emission Monitoring System is the real-time monitoring of atmospheric effective means. It has been applied widely in China at present, but because our country started to study CEMS technology too late. So there is still a gap to the advanced world level. This paper is based on the domestic CEMS technology situation, using embedded system, we designed CEMS data acquisition and handling system based on AT91SAM9263.It can realize the real-time data acquisition, processing and displayed.This paper firstly introduces the status at home and abroad about CEMS, and the development direction of CEMS data collection and analysis system. And then we will introduce the composition of CEMS and some technical requirements about it as well as the connection between CEMS and the embedded system .And finally we briefly introduced the embedded system.Considering with the project’s actual demand, we introduced the hardware and software design .The part of the hardware design introduces the hardware composition and frame of the entire system .At the same time we introduced several aspects that we should pay attention to when we select the ARM processor. Then we shall introduce the detailed realization of every module including the AT91SAM9263 motherboard, the switch data acquisition, the analog data collection and the bus design of CAN. In system software design part, this paper makes a detailed analysis of system software design, Including Windows CE operating system transplantation, the overall structure of the system application software and the realization of the specific module, Windows CE application design, the software design of the switch quantity and analogue data acquisition module, software design of CAN bus .We also gives the system operation working sketch.At the end of this paper, it gives a summary of itself and some preliminary thoughts about the further promotion to the shortage of this system. We prepare for the further research of this topic.
