Design of γ Dose-rate Remote Monitoring System Based on Optical Fiber Communication

For the safety of radiation protection for people who work in radioactive environment, the γ dose-rate needs be monitored. The remote distributed monitoring system is designed based on RS-485 bus and optical fiber communication project. The system has better anti-interference ability and high reliability. Win API functions are used in the monitoring and control program. Serial communication efficiency is improved by multithreading technique and custom messages response mechanism. The field running results indicate that this system is reliable and satisfactory.
