Risk early warning method for electric energy meter automatic verification line

Abstract

The invention discloses a risk early warning method for an electric energy meter automatic verification line. The method includes the following steps that: step 1, a risk index system is established; step 2, an index influence scope evaluation module is established; step 3, an early warning response module and an early warning directional push module are established; step 3, indexes in the risk index system are monitored, so that risk index data can be obtained, and whether a risk has been formed is judged; and step 5, when it is judged that the risk has been formed in the step 4, an early warning response event in the early warning response module is triggered based on the risk index data and the index influence scope evaluation module, and risk early warning content is pushed to users in different roles through the early warning directional push module. With the method of the invention adopted, early warning information can be provided for operation and maintenance personnel effectively before the occurrence of faults, and the operation and maintenance personnel can be assisted to avoid system risks and reduce the probability of the occurrence of faults.

Description

technical field [0001] The invention belongs to the technical field of electric energy measurement and detection, and relates to a risk early warning method for an automatic calibration line of electric energy meters. Background technique [0002] The automatic verification line of electric energy meters realizes the functions of verification, distribution, and storage of electric energy measuring instruments, and is composed of verification devices, AGV, robots, storage systems, sealing systems, and conveying lines. The equipment layout is scattered, the production process is highly uncertain, and the production control is more complex and changeable. Any failure in any link will affect the operation rhythm of the automatic verification line, especially the failure of a key link will cause the production system to stop running and reduce the measurement and verification capacity. , leading to delays in production planning and distribution planning. Therefore, it is very ne...

Problems solved by technology

[0003] At present, the operation and maintenance of automatic calibration lines by power metering units in other domestic grid provinces is still at the stage of fault monitoring and processing, that is, to restore the operation of automatic calibration lines by discovering faults, diagnosing faults, and handling faults. This method focuses on the occurrence of faults The final processing and recovery of the automation line is suitable for dealing with the faults that have occurred. Although the faults can be finally resolved, the automation line users still cannot avoid the loss of production and waste of labor
