基于虚拟仪器的电源仿真平台系统设计

Design of Power Simulation Platform System Based on Virtual Instrument

为了向航电系统的数据控制单元提供仿真激励运行环境,从而实现航电系统的交联试验和接口功能验证,设计了电源仿真平台系统。该系统以虚拟仪器为设计核心,基于美国国家仪器公司(NI)的工业化总线PXI平台以及LabVIEW软件平台,仿真实际电源子系统的离散量、模拟量和总线通信信号。实际现场运行表明,该系统能够完全替代原进口的仿真系统,且也为其进一步开发升级提供了保证。

In order to provide simulation environment for data control unit of avionics system and fulfill the demand of avionics system test, power simulation platform system which is based on virtual instrument is designed. By PXI technology and LabVIEW platform, the system is able to simulate discrete signal, analog signal and data bus communication. According to on-spot debug result, power simulation platform system can replace the former system which is imported and makes it possible to further improvement and upgrade the system.
