摘要
无线通信设备使用中,通常需要得知其接收电平和接收信噪比等参数,对没有配置显示界面的无线通信设备需要依赖网管计算机进行监控。在实际使用状态仅需要监视设备运行状态时,采用网管计算机又略显笨重,设计了一款小巧便携、适合外场使用的设备参数监视终端。终端以MSP430单片机为核心,通过串口与设备进行通信,获取发送参数和接收数据,通过与设备网管参数比较,解析通信协议,选择接收电平和接收信噪比等重要参数进行显示,并提供信号强度指示和强电磁干扰报警。通过实测,监视终端能正确显示通信设备参数,且携带使用方便。系统中的串口通信协议解析方法对含串口的设备再开发具有通用性。
It usually needs to know the receiving parameters such as level and signal-to-noise ratio, etc. , when using the wireless communication device, while the communication equipment without a screen depends on the managing comput- er. The portable terminal is designed because of the inconvenience of the computer when the using model is fixed and just monitoring is needed. The terminal with MSP430 MCU as the core intercepts the sending parameter and receives data via a serial port. The communication protocol is analyzed by comparing the receiving data and network data. The portable monitoring terminal has functions of data display, power indicator and strong electromagnetic interference alarm. The method of parsing the serial communication protocol has the universality in the equipment development with the serial ports.
