摘要

摘要: 航天器电子设备的地面综合测试是航天器研制过程中的重要环节，对设备功能验证及性能评估具有重要作用.传统的地面综合测试系统可重用性差，导致研制周期长且人力、设备投入较大.嫦娥四号着陆器载荷电控箱的地面测试系统采用模块化、可重用和CPU+FPGA单机集成体系结构，是集供配电测试、1553B通信总线仿真测试、间接指令测试、异步串口通信测试、实时数据处理等功能于一体的综合测试系统，适用于航天器电子设备单板调试、单机测试、软件配置项测试以及环境模拟试验等不同类型的测试.通过嫦娥四号着陆器载荷电控箱各项接口、功能、性能指标等的测试，证明该系统满足支持设备单机调试、软件配置项测试、状态确认和问题排查等测试需求，有力支撑了嫦娥四号着陆器载荷电控箱的单机设备研发，为嫦娥四号着陆器任务实施提供了有效保障.

Abstract: The ground comprehensive test of spacecraft electronic equipment is an important part in the development of spacecraft. It plays an important role in equipment function verification and performance evaluation. The ground test system of the Chang'E-4 lander load electric control box adopts modular, reusable design and CPU+FPGA single-machine integrated architecture. It can provide power supply test, 1553B communication bus simulation test, indirect command test, asynchronous serial communication test, real-time data processing and other functions in one integrated system, is suitable for spacecraft electronic equipment single machine debugging, configuration test and environmental simulation test and other types of test requirements. The test of each interface, function and performance of the load electric control box indicates that the system meets the test requirements of stand-alone debugging, status confirmation and troubleshooting of the spaceborne equipment, which strongly supports the successful on-orbit operation of the Chang'E-4 lander load electric control box.
