Research On Technology Of Field Mobil Location Environment Monitoring Based On BeiDou Satellite

It's the basis to protect water source and prevent pollution by obtaining information through monitoring water quality. As the development of economy, it's quite emergent to apply the modern water-quality-monitoring to construct the automatic remote water-quality-monitoring system so as to realize the automation of data collection and transport.At present, most water-quality-monitoring systems use the method of mobile communication, whereas the mobile communication relies on the ground infrastructure and is limited by geographical conditions. The satellite communication is not affected by geographical conditions, has the advantages of no blind area of communication and fast.This paper, on the basis of BeiDou satellite's communication and position principle, studies and develops the system of field mobile location environment monitoring based on BeiDou satellite, analyses the principles of communication and position of BeiDou satellite. Then it explains how to develop the General Data Acquisition Terminal with PIC16C57 by referring to the principle, interface, and data communications protocol of environmental multiple-parameter sensors YSI and satellite terminal modules.This project is for general purposes and can be applied in many fields of monitoring environments, such as hydrology, water conservancy, and weather.
