Abstract:随着天文技术的不断发展,远程观测和自主观测逐渐成为天文观测的主流趋势,自动调焦技术也越来越受到重视。电动调焦器是天文望远镜不可或缺的附属设备,是实现自动调焦的关键设备。为实现云南天文台丽江天文观测站10英寸米德望远镜的自动调焦,自行研发了一套天文电动调焦器,设计相关控制电路,制定串口通信协议,并编写了一套开源ASCOM驱动程序SS Focuser。本文详细介绍了该电动调焦器的结构原理和实现方法,实测结果表明具有很好的稳定性,完全满足设计要求,为天文电动调焦器设计提供了可借鉴的经验和方法。

Abstract: 丽江 2.4 米望远镜的圆顶采用方位随动和滑动式天窗的超半球结构,起初 为改善因圆顶和望远镜终端电子设备引起的内外大气湍动设计了大面积的多组 机械式侧窗。但由于高平台手动操作危险、缓慢、不精确且易坏,为解决侧窗的 稳定的多组自动控制,开发了基于 STM32 板的嵌入式设计的圆顶侧窗自动控制 系统,利用 WiFi 模块、串口模块和手柄,实现侧窗的远程控制和多通道控制; 同时结合气象数据、圆顶位置信息等使系统能根据气象阈值进行预警、自动开合、 并使风对望远镜振动影响尽量小。侧窗控制系统的设计也可满足上层系统集成的 需要,系统稳定可靠,能满足侧窗的自主运行与人为可控。

Abstract: The Lijiang 2.4-meters telescope has equipped several observation instruments at its Cassegrain focus. In order to maximize the observation efficiency, we need to realize the integrated control system for all the instruments. However, the original multi-band photometry control system doesn’t satisfy the requirements of integrating with other instruments, and needs to be redeveloped. Based on the study of the control system for YFOSC and the telescope, we redeveloped the control system of PICCD under the Linux system. We designed and completed three main modules: observation control program, device control program and instrument database, which has the unified control mode with YFOSC and telescope, make PICCD has the ability to be integrated with the control system of other instruments, and can finally meet the requirement of instrument control system(ICS) which can control all the instruments equipped on 2.4m telescope.
