摘　　要：圆顶是天文望远镜系统的重要外围设备,随着望远镜技术的发展,圆顶控制技术得到不断进步。为实现云南天文台自动差分像运动大气视宁度监测仪完全自动化,开发了一套基于ASCOM和Modbus/TCP协议的圆顶控制系统。结合ASCOM天文技术标准和Modbus/TCP协议规范,详细介绍了系统的结构原理和实现方法。实测结果表明,系统具有较好的稳定性和兼容性,完全满足自动观测的需求,为中小型天文望远镜圆顶设计提供了经验和方法。Astronomical dome is an important peripheral of optical telescope system, with the development of the telescope technology, astronomical dome control technology has also been improved. In order to realize the full automation of Yunnan observatory Automatic Differential Image Motion Monitor （ADIMM）, an astronomical dome control system based on ASCOM and Modbus/TCP protocol is developed. Combined with ASCOM astronomical technical standard and the Modbus/TCP protocol specification, the control system structure principle and realization method of Yunnan observatory ADIMM astronomical dome control system is introduced in detail. The measured results show that the dome control system has good stability and compatibility, which fully meets the requirements of ADIMM automatic observation, and it provides a reference of experience and methods for the designs of the small and medium-sized astronomical telescope dome.
