Reliability test method of instrument electric control system

Abstract

The invention discloses a reliability test method of an instrument electric control system. The reliability test method of an instrument electric control system comprises the steps of: collecting historical fault data of an electric control system and storing the historical fault data in a fault database; calculating the fault rate of each component of a plurality of components included in the electric control system according to the historical fault data; determining the components with the failure rate of more than or equal to 50% as test components; determining a plurality of test items ofa reliability test for the electric control system according to the fault type of the test components; respectively implementing each test item of the plurality of test items on the test components, and recording test data; and determining the reliability of the electric control system according to the test data. By adopting the method, pertinence of a product reliability test can be improved, faults of the product can be detected quickly, the test period is shortened greatly, research and development personnel can acquire the reliability of the product quickly, an electric control system of the product is improved better, and product quality is improved.

Description

technical field [0001] The invention relates to the field of reliability testing, in particular to a reliability testing method of an instrument electric control system. Background technique [0002] With the increasingly fierce market competition, there are more and more high-reliability and long-life products in the field of civilian household appliances. If the conventional reliability and life test methods are used to evaluate the reliability and life characteristics of the product, it is necessary to test all the components contained in the electronic control system of the instrument, and the test items for the electronic control system of the instrument are the same, so that Not only will it take an unbearable time cost, but even before the test is completed, the product has been updated or eliminated due to backward performance, and the test of the electronic control system of different instruments is not targeted, which is not conducive to the rapid discovery of the ...

If the conventional reliability and life test methods are used to evaluate the reliability and life characteristics of the product, it is necessary to test all the components contained in the electronic control system of the instrument, and the test items for the electronic control system of the instrument are the same, so that Not only will it take an unbearable time cost, but even before the test is completed, the product has been updated or eliminated due to backward performance, and the test of the electronic control system of different instruments is not targeted, which is not conducive to the rapid discovery of the electronic control system of the instrument. System fault location

Obviously, such a long test time and low test pertinence not only miss the best time to improve product reliability, but also seriously affect the progress of research and development, which is unacceptable in engineering practice
