Abstract

The invention provides a device evaluation method, and the method comprises the steps of building an evaluation index system of a device, receiving the parameter values of the to-be-evaluated indexesgenerated by the device in an operation process, wherein the evaluation index system comprises a plurality of key components, and each key component comprises a plurality of to-be-evaluated indexes; inputting the parameter values into a membership function, and outputting a membership numerical value of each to-be-evaluated index; calculating the first weight of each key component in the evaluation index system, and generating a first matrix by using all the first weights; converting the membership numerical value into an evaluation numerical value, and converting the evaluation numerical value into a fuzzy matrix through a fuzzy comprehensive evaluation method; and generating the plurality of target evaluation numerical values of the device through the first matrix and the fuzzy matrix, according to the corresponding relationship between the target evaluation numerical values and the evaluation results, selecting the evaluation result corresponding to the maximum target evaluation numerical value from the plurality of target evaluation numerical values as the target evaluation result. According to the present invention, the evaluation result is simple and clear.

Description

technical field [0001] The present application relates to the technical field of device evaluation, and in particular to a device evaluation method, device, terminal and computer readable medium. Background technique [0002] The integrated transmission device is the core power transmission of the vehicle. The integrated transmission device includes key components such as the oil supply system and the steering pump motor. Each key component includes multiple indicators to be evaluated. For example, the indicators to be evaluated for the steering pump motor include: high pressure valve group Steering high pressure, servo system servo pressure and rotor component charge pressure. These key components play a vital role in the operation of the vehicle, and the health status of the integrated transmission will affect the safety of the vehicle. Therefore, it is necessary to conduct a health assessment of the comprehensive transmission of the vehicle. The current assessment method...
