一种电子信息装备模块的故障确认方法及装置

A Method for Fault Confirmation of Electronic Modules Based on Detecting Device

电子信息装备为了实现功能扩展,方便维护,更多地采用模块化设计,随着系统功能越来越复杂,其模块组成间信号交联也越来越复杂,导致模块出现故障后难于检测和故障定位。提出一种基于检测热台的故障确认方法,检测热台将关联性强的模块组成相对独立的功能单元,通过换插模块配合自动测试设备完成模块故障确认,该检测热台装置拓展了同等规模测试系统的应用范围。

In order to realize the function expansion and maintenance, most electronic equipments adopt the modularization design. As the function of system becomes more complex, it is difficult to detect module fault due to the complicated cross-linking signal between modules. In order to solve the problem, a test method is proposed based on detecting device. A virtual unit for strongly correlated modules is formed in the detecting device. The modules could be changed under test in the detecting device and the fault confirmation could be comploted by computer control. The test method is developed and success to complete some engineering tests. Results indicate that the detecting device expands the function of test equipment.
