Read Abstract +

This paper introduced a telescope control system based on ZeroMQ communication architecture to realize the coordination and scheduling control of mount, camera, dome, weather station and other equipment. The system can be divided into three layers: equipment interface layer, telescope control layer and business layer. In the instrument interface layer, the information interaction control between different devices and systems is mainly realized through ZeroMQ communication protocol. In the telescope control layer, each type of equipment is abstractly defined to realize the logical control of the equipment and the decomposition of upper control commands. The business layer mainly takes time series as the main line, schedules equipment to complete various tasks, monitors and manages environmental status information, telescope equipment status, task execution status and other data, and realizes automatic observation and exception handling of telescopes. The system has been applied to the 36 cm telescope on the Korla observation. It is mainly used for automatic observation of space debris and has achieved good results.
