The Design and Implementation of the Compressor Pressure Monitoring System of 26 m Radio Telescope in Xinjiang Astronomical Observatory

The receiver is cooled by helium of the 26 meter telescope at Nanshan in Xinjiang Astronomical Observatory, Chinese Academy of Sciences. The compressor need to be maintained regularly, the helium tube may leak due to wear. The condition of the compressor affects the normal observation of the 26 meter telescope. According to the actual demand of monitoring pressure of compressor, the compressor pressure monitoring system is designed and developed, it can realize the following functions, such as recording compressor pressure, real-time monitoring, real-time alarm, sending alarm information and daily report of compressor pressure by email, querying the historical work record of compressor, processing compressor alarm information and so on. This paper introduces the framework of the software system, the software flow the principle of data processing, the idea about how to realize the software system, the function of software module and the human-computer interface. The software has the following advantages, such as rapid alarm, powerful query function, simple and friendly human-computer interface, strong expansibility and other advantages, which can meet the needs of current and future applications.
