本文描述了用于内部测试系统的微计算机,它为标准的电子组件结构雷达装置提供了自动和连续的性能监测及故障隔离功能。为了能检测和诊断主系统的故障,存贮程序的微计算机能够综合处理过程中的错误,并且在通过改变程序以适应主系统的改型方面都表现出灵活性,其所需费用以及设备尺寸均与只起保障功能的分系统相称。内部测试设备引起系统失效的可能性是很小的。这是由于内部测试设备局限于监测而与主系统互不影响。与完全有源测试设备相比它具有更复杂的处理过程并降低了故障隔离电平。文中还给出了遍布整个主系统的几个独特的测试线路的内部测试系统硬设备简明配置图。
This article describes a microcomputer for use in an internal test system that provides automatic and continuous performance monitoring and fault isolation for a standard electronic assembly-based radar unit. In order to be able to detect and diagnose faults in the main system, the microcomputer in which the program is stored can synthesize the errors in the process and show flexibility in adapting the program to the modification of the main system, the cost thereof and the size of the equipment Both are commensurate with the subsystems that only function as a safeguard. The possibility of system failures caused by the internal test equipment is minimal. This is because the internal test equipment is limited to monitoring and does not affect the host system. It has more complex processing and lower fault isolation levels than fully active test equipment. The article also gives a concise configuration diagram of the hardware of the internal test system for several unique test circuits throughout the main system.
