由于传统基于实物的测试性验证方法存在部分故障无法注入或注入后易导致装备硬件损伤等局限,测试性验证工作正朝着具有低成本、高效率、可重复、过程可控、零风险等优势的半实物仿真甚至于全数字虚拟仿真试验方向迈进。文中拟借助计算机强大的计算能力和可视化技术开发一套雷达天线阵面的测试性虚拟验证系统,通过引入多智能体仿真技术建立了能够模拟其结构、功能及运行状态的虚拟样机,利用LabVIEW 平台实现了故障样本量的选取及故障样本分配等功能;为实现虚拟样机的仿真故障注入,提出了一种多智能体虚拟样机与LabVIEW 平台的通信方法。通过故障注入仿真试验表明,虚拟样机可快速、有效地识别注入的故障并对其进行隔离,而且能动态显示故障在各智能体之间的传播路径,证明该系统可为测试性验证提供了一种高效、低成本的虚拟验证新途径。

Due to the limitations of traditional physical-based testability verification methods that some faults cannot be injected or can easily cause equipment hardware damage after fault injection, the testability verification work is moving towards low-cost, high efficiency, repeatable, process-controllable, and zero-risk advantages. The hardware-in-the-loop simulation is even moving forward in the direction of full digital virtual simulation experiment. In this paper, a testable virtual verification system for the radar antenna array is developed with the help of powerful computer computing power and visualization technology. By introducing multi-agent simulation technology, a virtual prototype that can simulate its structure, function and operating status is established. The function of selecting fault sample size and distributing fault sample is realize by using LabVIEW platform. In order to realize the simulation fault injection of the virtual prototype, a communication method between the multi-agent virtual prototype and the LabVIEW platform is proposed. The fault injection simulation results show that the virtual prototype can quickly and effectively identify the injected faults and isolate the injected faults, and it can dynamically display the propagation path of the faults between the agents. It is proved that the system can provide a new way of virtual verification with high-efficient and low-cost.
