Design and Development of Comprehensive Control System for Quantum Science Experimental Optical Ground Stations

"Micius" quantum science experiment satellite (referred to as "Micius") is the world's first satellite engaged in quantum science experiments at the space scale. "Micius", together with four optical ground stations for quantum science experiments and one optical ground station for quantum teleportation, has built a platform for satellite-ground quantum science experiments. In order to realize the integrated coordination of the optical ground stations of quantum science experiment, it is necessary to develop a set of integrated control system of quantum science experiment (referred to as the integrated control system of ground station). The integrated control system of the ground station consists of four quantum science experimental optical ground stations, including two new optical ground stations and two modified ones, and the unified interface and platform need to be established for them. In this paper, the integrated control system of the ground station is divided into web service layer, network interaction layer and device control layer by adopting the layered and modular design method, refers to international standard interfaces and according to the functional requirements of the optical ground station in quantum science experiment. The designed ground station integrated control system has realized the following functions:(1) the release of scientific data; (2) the interaction between internal and external data; (3) the analytical implementation of the scientific experiment plan of the quantum scientific experiment satellite project; (4) monitoring the environment and equipment conditions of the station. As a unified control platform for the optical ground station of quantum science experiments, the integrated control system of the ground station provides a strong guarantee and support for the overall coordinated control of the optical ground station of quantum science experiments. At the same time, as a general ground station control system, it has the advantages of being easy to transplant to other telescope control system.
