摘要
介绍坐落在上海世博园内TWP3边界层风廓线雷达系统发射机控制系统设计思路及其功能特点。控制系统基于FPGA和单片机的程序控制实现手段。系统功能包括状态监控、射频通路控制、故障诊断定位、自动保护和自修复。发射机的各个监控量会在本机液晶屏幕显示以便用户的使用和观察,同时将重要的参数上传等。该控制系统自身监控功能的完善,对于发射机本身的调试以及在整个雷达系统的联合调试测量中都起到了至关重要的辅助作用。
The design ideas and features of the transmitter control system of the TWP3 boundary-layer wind profiler,which was located in the World Expo Park,are described.Based on the effective mechanism of repetitive judgment and reset,the control system implements the on-line monitoring of the transmitter,RF switch control,fault location,and self-protection by the programmable language FPGA and microcontroller.The sampled data for the control circuit includes voltages,temperature and RF signals,and fault information which would be visually displayed on the screen of the transmitter and also be uploaded to computers.The control system played an important role in debugging the transmitter and relative parts of the wind profiler.
