多制式基站探测终端设计与实现

多制式基站探测终端基于S3C2440设计而成，使用内存映射方式扩展多路串行通信接口，内置多制式通信模块。将该终端置于移动监测车辆之中，在监测车辆移动过程中，终端实时、周期性监测热点所在区域三大运营商不同制式的无线网络信号，包括GSM，CDMA，WCDMA，TD-SCDMA，并将采集获得的GPS信息、基站参数、信号强度等上传至管理软件，管理软件在线分析获取监测区域全网信号图谱。该系统的使用填补了目前无线通信全网实时同步监测的市场空白，丰富了无线网络监测手段。

Design and implementation of multi-standard base station detecting terminal

The design of a base station detecting terminal based on S3c2440 is presented in this paper. Its serial ports are expanded by memory mapping mode. The multi-standard communication module is built in this terminal. The terminal is moun-ted in the special vehicle to monitor the different signals of wireless networks while it moving on the road in the hot point area. Its monitoring targets are GSM,CDMA,WCDMA and TD-SCDMA. The parameters of base station,signal intensity and GPS in-formation collected by the terminal is sent to the management software,which analyzes a signal mapping spectrum of each net-work in the region in real time. This system fills the gap to execute the real-time simultaneous monitoring of all the wireless cam-munication networks in the region.
