基于GPRS的无线远程气象数据采集传输系统设计

Design on the transmission system of wireless remote meteorological data collection based on GPRS

设计了1款基于GPRS的无线远程气象数据采集传输系统。本系统详细介绍了低功耗单片机MSP430与GPRS模块,温度、湿度、风向等各类传感器的硬件接口设计;论述了GPRS数据传输、低功耗、以及频率型、电压型输出信号传感器的信号测量等软件的设计,并给出了低功耗和GRPS数据传输的测试结果。通过测试表明,该系统能够满足实际需求。该系统可用于岛屿、高山、偏远等环境较为恶劣、地面通信手段缺乏地区的气象数据采集和传输,对于气象部门及时掌握这些的即时气象信息具有十分现实和意义。

This paper designs a transmission system of wireless remote meteorological data based on GPRS,which introduces in detail the designs of low power single chip MSP430,GPRS module and the hardware interface of various types of such sensors as temperature,humidity and wind direction,discusses the software designs of GPRS data transmission,low power as well as the signal measurement of frequency,voltage output signal sensors,and shows the test results of GPRS data transmission and the low power.The test shows：this system meets practical needs,and it can be used for meteorological data collection and transmission in such regions as islands,mountains and remote places where the environment is relatively bad and the ground communication means is shortage.And it is of very practical significance for meteorological departments to grasp real-time meteorological information.
