摘要
为测试CMMB网络的覆盖情况,文中设计了基于处理器STM32及GPRS无线通信方案的CMMB智能网络监测系统。处理器通过解调模块和GPS模块采集信号质量的相关参数和地理位置信息,并通过GPRS模块将信息发送给服务器,同时接收服务器端的命令,完成终端与服务器的双向通信。终端利用太阳能供电,使其可长期工作在缺少电源、无人监管的状态下。经测试,系统工作性能稳定。
In order to test the coverage of CMMB network, an intelligent network monitoring system base on STM32 and GPRS wireless communication scheme is designed in this paper. CPU collects the parameters of signal quality and location information using demodulation and GPS modules, and then transmits these information to server and receives command from server using GPRS module to achieve two-way communication between terminal device and server. Terminal devices are powered by solar energy so that they can be operated in the situation of none-supervision and lack of power for a long time. After test, this system has a stable working performance.
