Fault diagnosis system for electric power measurement automatic verification assembly line

Abstract

The invention discloses a fault diagnosis system for electric power measurement automatic verification assembly lines. Production control strategies of assembly lines are independent from one another at present, the production efficiency is severely affected, and potential safety hazards are caused for automatic production equipment. The fault diagnosis system comprises a data acquisition and processing module, a diagnostic analysis module, a system configuration module and a function display module, wherein the diagnostic analysis module implements offline analysis service and online diagnosis service, the offline analysis service includes establishment of a system SDG model, layering of an HSDG model, classification of target variables, establishment of a determined variable PS model and establishment of a variable DKPLS SVR model to be evaluated, and fault factors are extracted and serve as nodes of the HSDG model through manual abstraction of a physical structure of hardware equipment and by combining with historical production data information. The fault diagnosis system can reduce the searching space of effective nodes, thereby accelerating the fault diagnosis speed.

Description

technical field [0001] The invention belongs to the field of electric power metering, in particular to a fault diagnosis system for automatic verification assembly line of electric power metering. Background technique [0002] The demand for smart energy meters will increase day by day. The future metrological verification work will not only ensure the quality of verification, but also put forward higher requirements for the number of verification. The current automatic verification assembly line for electric power metering relies on intelligent warehouses to promote production and business circulation, and realizes inventory management, storage and exit, verification and loading, appearance inspection, pressure test, verification and testing, sealing and labeling of measuring instruments, etc. However, due to the fact that the production control strategies between the various assembly lines are independent of each other, congestion and starvation are prone to occur. As a re...
