Abstract:The control and protection logic in the monitoring and controlling system of the antenna guarantees the security for the operation of the antenna equipment. In view of the requirements of the monitoring and control system of the antenna, the control strategies of various protection modes for the antenna movement are compared, and the kernel control flow of the antenna is proposed. Based on the real-time alarm information processing methods, a kind of software control and protection logic for abnormal processing of the antenna monitoring system is designed, and the debugging strategy and method of the logic program in the laboratory environment are devised. The logic programs only can be used as a simulation test in the laboratory environment and the programs needs to be improved in the real environment(with antenna and real sensors). Security system design and implementation of the antenna system is complex. This paper provides a method to formalize and simplify these problems.
