Research Of Continuous Emission Monitoring System

In recent years, environmental issues have become the focus of human attention. Environmental monitoring is the important foundation for environmental protection. The effective monitoring to the environmental quality and polluting source emission is one of the important symbols of the scientific level of environmental management.CEMS (Continuous Emission Monitoring System) is developed considerring the need of the real projects, by analyzing the tecnique problem. As we know that the powerful control that MCU do in the industry,so we disign the CEMS.CEMS bases on the MCU8051F020, and we develop the data collecting, GPRS or CDMA to finish CEMS, andmore we design the human interface.This paper first introduces the basic concept and characteristics of MCS-51series, Secondly introduces continious emission monitoring system function and every part function, Third, detailed introduces the hardware system design, system hardware system is mainly for the core extensions8051F020microcontroller and circuit design, Fourth introduce the drivers and applications design, and introduces the serial driver, keyboard and screen drivers etc, And further more, we research the wireless domain, in the CEMS systerm we expand the GPRS module or CDMA module, and finish the communication protocol design relating GPRS/CDMA network, realize the transmission by the wireless. in the paper we have the detailed introduce of the whole systerm frame and every part. and in the paper we refer to the single-chip computer technology, sensor technology, and the GPRS/CDMA wireless transmission technology, etc.
