四川稻城县无名山址点是云南天文台新近选定的天文台址。为实现在无名山50 cm光学望远镜开展远程自动观测,需要对圆顶进行远程自动控制驱动开发。基于天文公共对象模型(Astronomy Common Object Model, ASCOM)标准,采用Modbus/TCP协议连接可编程控制器(Programable Logical Controller, PLC),实现了圆顶的自动控制。重点介绍了圆顶控制原理和实现方法,结果表明,圆顶控制系统具有融合度高、使用方便的特点,满足远程自动观测的需求,对于中小型观测系统具有一定的借鉴意义。

Mountain Wumingshan, located in the Daocheng county, Sichuan province, was sited by Yunnan Observatory recently. For the purpose of carrying out remote automatic observation test with 50cm telescopes on Mnt. Wumingshan, development of the dome-driver is required. The driver which was based on ASCOM standard and connected to PLC controller with Modbus/TCP protocol, realized the automatic control of dome. This paper mainly introduced dome control principle and realization method. The results showed that the control system of the dome is characterized by its high alignment and convenience. Besides, it can meet the needs of remote and automatic observation and can be used as a reference for similar small and medium-sized observation systems.
