Abstract

The invention relates to a detection electronic box failure diagnosis adapter. The detection electronic box failure diagnosis adapter adopts the following technical scheme that the detection electronic box failure diagnosis adapter comprises an analog signal conditioning circuit board, a digital signal conditioning circuit board, a voltage signal switching control module and a panel, the panel is provided with a VPC-9025 interface module connection block, an insertion module and a tested printed circuit board support, and a detection system is formed through the butt joint between the adapter and a test platform through the VPC-9025 interface module. According to the invention, detection, failure judgment and failure locating can be performed on a detected signal outputted by a printed circuit board of 16 circuit assembly part single board cards of a detection electronic box according to the detection time sequence and process of the detection electronic box, and electronic devices leading to printed circuit board failures are reported in the report printing manner, so advantages of easy operation and good reliability can be realized.

Description

technical field [0001] The invention belongs to the field of weapon system fault detection equipment, and in particular relates to a fault diagnosis adapter for a detection electronic box. Background technique [0002] In the maintenance process, two conditions are required: the first is the detection condition, that is, to provide power and excitation conditions for the product, and then use a multimeter or oscilloscope to detect various parameters of the product; the second is the expert condition, and the expert uses its solid Professional knowledge and rich experience analyze these parameters to find the cause of the failure. [0003] At present, the maintenance of the detection electronic box mainly depends on the detection and maintenance equipment. On the one hand, the detection of the product is not comprehensive enough, on the other hand, the requirements for the maintenance personnel are very high, and sometimes experts have to be invited to the site to solve the ...
