Software design for automatic changing feeds control system and video surveillance

This paper describes a 25m large-scale radio telescope's automatic control system of changing feeds. The software enables a good man-machine interface for automatic changing feeds instead of artificial changing feeds, which saves us a lot of time for changing feed and improves work efficiency. This system has achieved remote control of equipment house, accurate location quickly, real-time collecting data. Through the cameras installed in equipment house and we can view the lifting and dropping state of the feed and achieve the automatic real-time monitoring for changing feeds.
