随着卫星技术的迅猛发展,对卫星电源系统的输出稳定性和可靠性,尤其对瞬间抗干扰能力等性能提出了愈来愈高的要求,因此卫星电源系统的测试和评估是一项重要的工作。提出了一种基于控制器局域网络(Controller Area Network,CAN)总线的卫星电源地面测试系统设计方案,该测试系统既可对卫星电源系统性能进行精确测试,并能满足不同型号卫星电源系统的测试要求。系统利用上位机通过CAN总线与地面电源系统进行通信,可实现对地面电源系统的多路工程参数遥测量的实时采样、对电源系统发送遥控指令测试。还可通过A/D通信端口实现对均衡功能的测试、工程参数的报警、数据各类报表的输出打印、历史数据的显示和数据维护等功能。
With the rapid development of satellite technology, higher and higher requirements are placed on the output stability and reliability of satellite power systems, especially for instantaneous anti-jamming capability. Therefore, testing and evaluation of satellite power systems is an important issue jobs. A design scheme of ground test system for satellite power based on Controller Area Network (CAN) bus is proposed. The test system can not only test the performance of satellite power system accurately, but also meet the requirements of different types of satellite power system Claim. The system uses the host computer to communicate with the ground power system through the CAN bus, which can realize the real-time sampling of the telemetry of multiple engineering parameters of the ground power system and send the remote control instruction test to the power system. Also through the A / D communication port to achieve the equalization function of testing, engineering parameters of the alarm, the data output of various reports print, historical data display and data maintenance functions.
