基于GPRS模块的远程毒气监测系统设计

Design of Remote Gas Monitoring System Based on GPRS Module

系统采用STM32F103RBT6为微处理器,运用华为GTM-900模块完成数据传输.阐述了基于GPRS模块的无线数据传输系统的工作原理,给出模块外围参考电路图和GTM-900的初始化以及接入GPRS网的AT指令.在此基础上,该简易系统用于毒气远程监测试验,且监测成功.实践证明,采用此模块,可方便简单地实现无线互联网的接入,实现毒气远程监控.

The STM32F103RBT6 was used as microprocessor and the huawei GTM-900 module was ap- plied to complete the data transmission in this system. The working principle of the wireless data transmission module based on GPRS module was stated and the corresponding reference hardware module of circuit diagram, the initial AT instructions of GTM-900 as well as AT instructions to how to access GPRS network were presented. On this basis,the simple system was used to remote gas monitoring tests. The result showed that wireless Internet access could be easily implemented simply and could realize long-distance detecting by using this module.
