Abstract

The invention relates to an infrared circuit box failure diagnosis device. The infrared circuit box failure diagnosis device adopts the following technical scheme that the infrared circuit box failure diagnosis device comprises a master control system, an excitation signal generation portion, a data acquisition portion and a panel. The master control system comprises a PC104 mainboard. The excitation signal generation portion comprises a signal conditioning board, a detection cable and a power source. The signal conditioning board at least comprises an attenuation filter circuit, a precise voltage source circuit, a power-on control circuit, and a source transformation circuit. The data acquisition portion comprises a data acquisition board based on a PC104 bus. The excitation signal generation portion is used to provide a power source and various required excitation signals for detected products. The master control system is responsible for the control and data processing of the whole system. According to the invention, not only the detect that detection parameters of an infrared circuit box detection maintenance equipment are not comprehensive is overcome to ensure the detection accuracy, validity and automaticity, and but also a specialist diagnosis system is implant onto the software, so failures can be judged and positioned accurately, and the maintenance operation can be effectively guided, so that infrared circuit box failure diagnosis device is suitable for being popularized and used in all levels of service stations.

Description

technical field [0001] The invention belongs to the field of weapon detection equipment, and in particular relates to a weapon infrared circuit box fault diagnosis equipment. 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 infrared circuit box mainly depends on the inspection and maintenance equipment. On the one hand, the inspection of the product is not comprehensive enough. Contents of the invention [0004] The invention proposes an infrared circuit box fault diagnosis device which integrates detection conditions and expert conditi...
