针对真空热试验设备中大规模电源测控的需求,在原有的外热流系统基础上,利用LabView平台重新设计了电源测控系统。该系统能够实现传统的大规模电源系统的灵活自动配置与控制,达到控制真空热试验设备中要求工况的目的,实现该电源测控系统软件的模块化更新,便捷地应对更换新型硬件电源所带来的软件更新需求。介绍了该电源测控系统的开发,包括其工作原理、硬件结构以及软件结构,重点介绍了LabView平台下的上位自动控制软件的设计。
Aiming at the demand of large-scale power measurement and control in vacuum thermal test equipment, the power monitoring and control system was redesigned by LabView platform based on the original external heat flow system. The system can realize the flexible automatic configuration and control of the traditional large-scale power supply system, achieve the purpose of controlling the required working conditions in the vacuum thermal test equipment, realize the modular updating of the power monitoring and control system software, and conveniently deal with the replacement of the new hardware power supply The software update needs come. The development of power monitoring and control system is introduced, including its working principle, hardware structure and software structure. The design of host automatic control software under LabView platform is introduced emphatically.
