新疆天文台26米射电望远镜压缩机压力监控系统设计与实现

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

新疆天文台南山基地26 m射电望远镜的接收机使用氦气压缩机制冷,压缩机需要定期维护,氦气管在使用过程中会因为磨损而漏气,影响望远镜的正常观测。针对压缩机压力监控的实际需求,设计开发了一套压缩机压力监控系统,可以实现压缩机压力记录、实时监控、实时报警、通过邮件发送报警信息及压力日报表、查询历史工作记录、处理报警信息等功能。介绍了软件系统的框架、软件流程、数据处理原理、实现思想、模块功能、软件界面。系统具有报警迅速,查询功能强大,界面简洁友好,扩展性强等优点,能够满足当前及未来应用的需求。

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.
