[Abstract]:As a payload of the Fengyun 3 meteorological satellite, the solar radiation monitor operates in the solar synchronous orbit. During the course of orbit, the solar irradiance is tracked and measured by its two-dimensional tracking system. In the course of simulating the ground test of the two dimensional tracking system of the solar radiation monitor, it is necessary to provide the light source to simulate the track of the sun in orbit, and to verify the tracking performance of the two dimensional tracking system. Therefore, the ground simulation system of solar ray in orbit for solar radiation monitor is studied in this paper. There is an angle change between the sun and the satellite during the motion of the satellite in orbit around the sun. The simulation system of the solar ray in orbit needs to simulate the change of the angle to simulate the orbit of the sun relative to the satellite. In this paper, a kind of light source mechanism which can realize the spherical motion trajectory is proposed. In the ground environment, the two-dimensional motion mechanism is used to realize the spherical motion trajectory. And through the light source in the mechanism to realize the parallel light source with uniform illumination from all angles to simulate the solar radiation of the instrument in orbit, at the same time according to the calculation theory of the solar azimuth on the satellite, The motion control algorithm of two-dimensional motion mechanism is determined, and the velocity and direction of two-axis motion of two-dimensional motion mechanism are controlled by single chip microcomputer to simulate the track of the sun when the instrument is in orbit. In this paper, on the premise of reliable parallel light source and two-dimensional mechanical structure, the electrical control system of the simulation system is designed by hardware circuit and software program after the investigation of the orbit solar ray track. The simulation of the orbit of the sun in orbit is realized, and the results are analyzed and verified by the ground experiments. In the electrical control part of the system, C8051F020 microcontroller is used as the core controller, and FPGA is used as the assistant control. The motion of the two-dimensional mechanism is realized by controlling the stepping motor, and the angle information of the simulated light source is fed back by the encoder to simulate the trajectory of the sun ray in orbit. The system is simple in structure, convenient for automatic control and of high practical value. The experimental results show that the designed solar ray simulation system has good performance, which is of great significance to the ground performance test of the two-dimensional tracking system of the solar radiation monitor.
