针对当前装甲装备火控系统电路组成与功能特点,对火控系统维修保养过程中的故障诊断方法与测试需求进行了研究,提出了一种火控系统半实物联合仿真方法,介绍了该仿真建模方法的设计思路与实现方法;该方法可充分发挥LabVIEW和Multisim软件的优势,通过半实物联合仿真的方法,以仿真模型代替部分或者全部火控系统部组件,能够很好地实现火控系统不同级别的电路功能模拟、故障复现,快速完成故障诊断分析,解决了当前装甲装备火控系统维修诊断设备通用性差、规范化程度低、开放性差,难以真实的模拟系统级、部件级功能、故障注入和故障检测等问题,为装甲装备火控系统故障诊断与测试设备开发提供了有效平台,为基层部队开展维修训练和维护保障提供了有效途径。

Aiming at electric circuit constitution and function characteristics for fire-control system of current battlefield armored equipment,carrying a research on fault diagnosis method and testing requirements in the process of fire-control system maintenance,a semi physical co-simulation method for fire control system is proposed in this paper.The design ideas,realization means and application function of the method are introduced.This method gives full play to the advantages of LabVIEW and Multisim,with the hardware-in-the-loop simulation method,using simulation model replacing part or all of the fire-control system components,realizes circuit function simulation and fault recurrence for different levels of fire-control system,fast completes fault diagnosis analysis.This method can solve the maintenance diagnostic equipment for fire-control system of current armored equipment in poor universality,the low degree of standardization,poor openness,difficult to really simulate function,fault injection and fault detection on system or component level,etc.So it can provide an effective platform for the development of fire-control system fault diagnosis and test equipment of our battlefield armored equipment,and provide platform for the grass roots units to carry out the repair and maintenance training.
