Embodiment Construction

[0057] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0058] The method provided by the invention is realized aiming at the fault diagnosis table. The specific form of the so-called fault diagnosis table is as follows: figure 1 As shown, the rows of the matrix correspond to different faults, and the columns correspond to different tests. An element in the matrix of 1 means that the test corresponding to its column can detect the fault corresponding to its row, and an element of 0 means that the test corresponding to its column cannot detect the fault corresponding to its row.

[0059] figure 2 It is a flow chart of the optimal implementation method for complex system testing. figure 2 Among them, the preferred implementation methods for complex system testing includ...

Abstract

The invention discloses an implementation method for the test optimization of a complex system in the technical field of test diagnosis in equipment production and maintenance process. The method comprises the steps of: initializing a system to be tested; preprocessing a fault diagnosis matrix labels.MC of the system to be tested; judging whether a set, namely labels-set, is an empty set, if the set, namely labels-set, is not the empty set, selecting a node as a current node from the set, namely labels-set, and preprocessing the current node; calculating the upper limit new-U of the current node; judging whether the current node is a leaf node, if so, processing other nodes in the set labels-set; otherwise, dividing the current node into two child nodes, and adding the two divided child nodes into the set, namely labels-set, and deleting the current node from the set labels-set, and then, processing other nodes in the set labels-set. The implementation method ensures that the optimal test points can be searched, and the high speed is satisfied.

Description

technical field [0001] The invention belongs to the technical field of testing and diagnosis in the process of equipment production and maintenance, and in particular relates to an optimal realization method of complex system testing. Background technique [0002] With the development of science and technology, there are more and more components in modern equipment or systems, and their functions are becoming more and more complex. There are many physical measuring points in the system, and there are many kinds of tests. However, in order to perform fault diagnosis on such a complex system or equipment, testing must be carried out first, and testing is an important means to obtain the information required for diagnosis. Without complete testing and sufficient information, it is difficult to ensure the accuracy of fault diagnosis. However, in the face of such a large set of feasible tests, how to select the least number of tests to meet the requirements of fault diagnosis i...
