Automatic detection device of hardware fault of whole electric energy meter and detection method thereof

Abstract

The invention discloses an automatic detection device of a hardware fault of a whole electric energy meter and a detection method thereof. The device comprises a power supply module, a CPU signal processing chip, a signal prompting LED lamp, a reset button, a signal detection port and a power supply port. According to the invention, before the whole electric energy meter is debugged, problems arefound in advance so that maintenance is performed, so occupation of a debugging bench body when fault products enter the next step is reduced; the bottleneck that the production device limits the yield is reduced; production efficiency is improved; before the whole electric energy meter is detected, hardware problems are detected in advance, so some repeated detection work of fault products lateris reduced and production and labor cost is reduced; and after the electric energy meter is assembled, the detection device carries out comprehensive hardware detection on the electric energy meter, so entering to the next production step of fault products is reduced; and production quality is improved.

Description

technical field [0001] The invention relates to an automatic detection device and a detection method for the hardware failure of the whole electric energy meter. Background technique [0002] At present, in the production process of the electric energy meter, after the complete assembly of the electric energy meter is completed, the hardware self-inspection is performed after power-on. The self-inspection content includes the power module, metering module, control module, storage module, communication module, and display module. After the inspection is completed, if there is no fault, the electric energy meter will directly exit the self-inspection mode and enter the normal operation mode; if there is a fault in the electric meter, the electric meter will display the corresponding error code on the LCD screen, and the maintenance personnel can repair it according to the code prompt. [0003] The existing hardware self-inspection method can only detect the power module, meter...

AI Technical Summary

Problems solved by technology

The infrared channel, RS485 channel, carrier communication interface, built-in switch action, external switch action, alarm switch action, second pulse signal, clock signal, etc. of the energy meter cannot be detected by self-test

The existing technology will cause the untested hardware part to flow into the next production link, and the above hardware problems will be gradually detected in the later debugging process. If there is a problem and repaired, it needs to return to the front end of the detection process for re-testing and debugging, which will affect the product. Quality and Productivity
