The Research of Space Telescope CCD Camera Image Resource Simulative System
The equipment that the payload electronic control box matches the satellite Charge-Coupled Device (CCD) camera must be rigorously tested before being put into use. The traditional testing process is to make it with the bulky CCD camera system docking and then to capture a certain image to analyze, this will cause a waste of time and material. In consideration for the above problems, a simulative CCD camera image resource system is proposed in this paper. The control signal of a simulative CCD camera image resource is usually implemented in the Field Programmable Gate Array (FPGA), thus increasing the complexity of the hardware language, and stability will fall and making post-adjustment is more trouble. This paper presents a system which is controlled based on the host computer software. It makes complex code integrate into the host computer and sets aside a adjust interface to the software in advance, achieving with the FPGA circuit board to send the picture generated by the system cycle together. Sending images, image display and serial communication are usually for a thread in the general simulative CCD camera image resource system, this will inevitably cause some problems that often appear in the process. However, the system utilizes a three-run thread synchronization mode which makes the system more flexible, very easy to adjust. Extensive tests show that the simulative CCD camera image resource system has been running with satisfactory results. So it can replace CCD camera to test the payload electrical control box, which is stable and reliable test for the project and provides a strong support.
