Embodiment 1

[0041] Please refer to figure 1 This embodiment provides a maintenance strategy formulation method that can be applied to the maintenance management of equipment failures. By establishing a risk matrix and using the different distributions of equipment failure causes in the risk matrix, not only can the risk of each failure cause be clarified Sorting, to formulate or adjust the maintenance strategy for each failure cause, and also to evaluate whether the corresponding maintenance strategy is reasonable. The following describes the maintenance strategy formulation method in detail.

[0042] Step S100: Create a risk matrix under the preset risk dimension using the mean time between failures of the equipment and the impact level of the preset risk dimension as indicators.

[0043] Considering that for different equipment failures, the probability or frequency of their occurrence may not be the same. In this embodiment, in order to understand the risk of each failure cause and then fo...

Embodiment 2

[0072] Please refer to Image 6 Based on the maintenance strategy formulation method of Embodiment 1 above, this embodiment provides a maintenance strategy evaluation device 100 based on a risk matrix, which can be applied to evaluate equipment failure risks and optimize corresponding maintenance strategies. The risk matrix-based maintenance strategy evaluation device 100 includes:

[0073] The risk matrix creation module 10 is configured to create a risk matrix under the preset risk dimension using the mean time between failures of equipment failures and the impact level of the preset risk dimension as indicators.

[0074] The risk level zone dividing module 20 is configured to divide the risk matrix into different risk level zones according to the mean time to failure and the impact level of the preset risk dimension.

[0075] The fault cause distribution module 30 is configured to obtain the mean time between failures of each fault cause according to the historical fault data of ...

Abstract

The invention discloses a maintenance strategy formulation method, a terminal and a computer storage medium. The method comprises the following steps: a risk matrix under a preset risk dimension is created by taking an average failure interval time of equipment failure and an influence grade of a preset risk dimension as indexes; The risk matrix is divided into different risk grade areas accordingto the mean failure time and the impact grade. According to the historical fault data of the equipment, the average fault interval time of each fault cause is obtained, and its distribution is determined according to the average fault interval time of each fault cause and the influence grade. According to the technical scheme of the invention, By establishing a risk matrix to visually display thecorresponding relationship between equipment risk and each fault cause, the risk sequence of each fault cause can be made clear and the corresponding maintenance strategy can be formulated, and whether the maintenance strategy of each fault cause is overhauled or not can be evaluated, so that the maintenance strategy can be optimized accordingly, and the limited maintenance resources can be reasonably allocated, and so on.

Description

Technical field [0001] The present invention relates to the technical field of equipment maintenance, in particular to a method for formulating a maintenance strategy, a terminal and a computer storage medium. Background technique [0002] The traditional evaluation and optimization of equipment maintenance strategy is to analyze the functions and failure consequences of each system of the power plant, and then further analyze the function failure and consequences of the equipment according to the function failure of the system. For equipment with more serious failure consequences, emphasis is placed on increasing preventiveness. Maintenance and point inspection work. [0003] It can be seen that in the currently commonly used equipment maintenance strategy formulation methods, since the main consideration is the consequences of equipment failures, corresponding maintenance or detection methods are added for failures with serious consequences. This method can reduce the risk of equ...
