【摘要】：卫星供配电测试系统是卫星电气地面支持设备中必不可少的组成部分,是卫星供配电系统能够安全的为卫星进行供电的重要保障。卫星供配电系统的性能好坏,会直接影响着卫星的飞行安全和寿命。因此,在卫星研制的各个阶段,必须对供配电系统进行严格的测试。本文针对卫星供配电测控系统在地面测试中需高效、可靠和扩展性好等要求,以研制出智能化、通用化、小型化、网络化的卫星测控设备为目的,提出了一种基于以太网的卫星供配电测控设备的设计方案。根据总体方案,在对卫星供配电系统的工作原理和系统功能进行详细分析的基础上,明确卫星供配电测控设备的结构组成和需完成的功能、指标,采用模块化设计方法,完成了测控设备的研制与测试。该测控设备由硬件和软件两部分组成。系统硬件由专用测试设备、自制调理电路、以太网数据采集卡和PC机组成。软件设计采用LabVIEW图形化语言,按照模块化设计方法,实现整星的供配电控制、脱落电电脱控制、重要参数的测量和状态的监视与记录。测控设备中采用以太网总线将各网络仪器设备连接起来,并通过控制计算机进行控制。其中以数据采集单元中的以太网采集模块为例,对网络设备的驱动程序进行设计,实现了数据实时、准确的发送和接收。最后对系统进行了软、硬件联调测试及误差分析。测试结果表明,系统的功能、各项指标和可靠性均符合相关规定和研制任务要求。
[Abstract]:Satellite power supply and distribution test system is an essential part of satellite electrical ground support equipment, and it is an important guarantee for satellite power supply and distribution system to provide power for satellite safely. The performance of the satellite power supply and distribution system will directly affect the flight safety and life of the satellite. Therefore, in the various stages of satellite development, the power supply and distribution system must be strictly tested. Aiming at the ground test in high efficiency and reliability and scalability requirements of distribution control system for satellite to satellite control equipment developed intelligent, universal, miniaturization and networking for the purpose, the paper proposed a design scheme based on Ethernet satellite power supply control equipment. According to the overall plan, detailed analysis on the working principle and system of the satellite power supply system function, function, index structure clear satellite power distribution control equipment and completed by using modular design method, completed the development and testing of the control equipment. The measurement and control equipment consists of two parts: hardware and software. The system hardware consists of the special test equipment, the self-made conditioning circuit, the Ethernet data acquisition card and the PC machine. The software design uses LabVIEW graphical language, according to the modular design method, to achieve the whole star's power supply and distribution control, the electrical control of falling off, the measurement of important parameters and the monitoring and recording of the state. In the measurement and control equipment, the Ethernet bus is used to connect the network instrument and equipment, and control by the control computer. Taking the Ethernet acquisition module in the data acquisition unit as an example, the driver of the network device is designed to achieve real-time and accurate data transmission and reception. Finally, the system has been tested with hardware and software and the error analysis. The test results show that the functions, indexes and reliability of the system are in conformity with the relevant regulations and the requirements of the development task.
