Problems solved by technology

There are many equipments in the automatic verification assembly line of electric energy meters, and any equipment failure will affect the normal verification work of electric energy meters. Therefore, it is necessary to carry out daily maintenance on each equipment of the automatic verification assembly line
Routine maintenance should be mainly aimed at those equipments that often break down and have a great impact on the normal test quantity, otherwise not only the test quantity of the electric energy meter cannot be improved, but also the waste of manpower and material resources will be caused

Abstract

An electric energy meter automatic verification production line device maintenance method. The method comprises the following steps: obtaining an unavailability U of a device according to a failure count of the device and a repair time for each failure; calculating to obtain an impact level F of the device on the production line; calculating to obtain a daily maintenance priority level coefficient P of the device; ranking devices according to the daily maintenance priority level coefficient P; setting a maximum threshold value and a minimum threshold value of the daily maintenance priority coefficient P; and finally determining the device maintenance method. The method applies a scientific basis to a daily maintenance plan for an electric energy meter automatic verification production line device; thereby, manpower and material resources are saved while the device reliability degree is improved, improving the quantity of electric energy meters verified and reducing the device maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of automatic verification of electric energy meters, and in particular relates to a maintenance method for automatic verification assembly line equipment of electric energy meters. Background technique [0002] At present, the electric energy meter has been verified by automatic verification assembly line. There are many equipments in the automatic verification assembly line of electric energy meters, and any equipment failure will affect the normal verification work of electric energy meters.
