The Study Of Embedded Operating System Applied In Comprehensive And Integrated Monitoring Base-Station Based On ZigBee Technology

With the development of society, Monitoring and Control System applications domain has unceasingly expanded, the functions of the monitoring system, reliability, ease of use, and so has also put forward a higher demand. In recent years, the great development of Zigbee technology embedded systems made the monitoring system performance improvement possible.This paper studies the design of the comprehensive and integrated monitoring system which collected environmental data through Zigbee wireless sensor networks, and enhanced the monitoring system layout flexibility; The sensors'data was managed and processed necessarily by embedded operating system,which enhanced the flexibility of data-processing and the overall performance of the system. The use of Zigbee technology and embedded operating system in Monitoring and Control system will be the characteristic in this paper's study.This paper first built the system development platform based on the AT91RM9200 development board, elaborated the development methodology of auxiliary equipment driver in embedded linux, analysed the Zigbee protocol necessarily, studied the realization of the Zigbee protocol under embedded linux, and determined the realization mode of Zigbee protocol in the design of this system. Then, the system boot process was analyzed, and the boot process has been optimized to increase start-up speed of the system, shortening start-up time. Finally, this article analysed the top application software detailedly, put forward the system evaluation index system and system improvements and follow-up work.
