根据空间相机的地面测试任务需求,提出以FPGA硬件和VC监控软件为基础构建星务仿真测试系统的方法。利用FPGA丰富的I/O资源解决传统测试系统集成度差、功能单一的缺点;说明硬件组成及设计方法,给出软件的工作流程与设计架构。测试结果表明,该系统可对空间相机进行全面的功能测试,提供相机在轨工作时所需的环境,可靠性好,具有广泛的工程应用价值。
According to the test requirements of the space camera, a method was put forward that establishing a satellite-affair simulation system based on FPGA hardware and VC software. Plenty of I/O resources of FPGA were used to solve the problems of integration and single function. Hardware structure and design methods were introduced. Then the working schedule and ar chitecture of the software were provided. Results of tests show the system can perform different functional tests of space camera, and provide required working environment for on-orbit-camera. This system turns out to be reliable and it possesses practical ap- plication value in projects.
