Problems solved by technology

However, it is currently limited to rectification of existing product designs to adapt to the actual use environment, and most of the test data retained after environmental tests have not been fully utilized
At the same time, at this stage, the design of most product environmental tests is only based on the expected use environment of the equipment, but there is no feedback and support from environmental test data. At the same time, due to various factors, when the evaluation of the product and its use environment is inaccurate, Will lead to unreasonable test plan
[0004] The current method of environmental test design for products is basically based on the experience of test designers, based on the actual use environment of the product, and based on relevant test standards. The frequency of environmental test items, comparison of stress levels, test There is no quantitative design for effectiveness, etc., so the efficiency of environmental tests cannot be guaranteed, and the cost of tests is increased

Embodiment 1

[0073] Such as figure 1 As shown, it is a schematic flow chart of the implementation of the environmental test scheme design method provided in Embodiment 1 of the present invention, which may include the following steps:

[0074] S11. For each test item, determine the test pass rate and fault sensitivity index of the test item according to the historical test data, the test pass rate is used to represent the proportion of historical test products passing the test item, and the fault sensitivity index is used It is used to characterize the failure sensitivity of historical test products participating in this test item.

[0075] During specific implementation, the test items of the environmental test may include but not limited to the following: high temperature test, low temperature test, temperature cycle test, alternating / constant damp heat test, vibration test, humidity test, salt spray test, impact test, solar radiation Test, low air pressure test, mold test, dust test, v...

Embodiment 2

[0117] Based on the same inventive concept, Embodiment 2 of the present invention provides an environmental test scheme design device. Since the principle of the above-mentioned device to solve the problem is similar to the above-mentioned environmental test scheme design method, the implementation of the above-mentioned device can refer to the implementation of the method. No longer.

[0118] Such as figure 2 As shown, it is a schematic structural diagram of the environmental test scheme design device provided in Embodiment 2 of the present invention, which may include:

[0119] The first determining unit 21 is used to determine the test pass rate and fault sensitivity index of the test item according to the historical test data respectively for each test item, and the test pass rate is used to characterize the ability of the test item to stimulate product failure, The fault sensitivity index is used to characterize the efficiency of the test item to discover product faults...

Abstract

The invention discloses an environmental test plan design method and device. With the environmental test plan design method and device of the invention adopted, the test items of an environmental testto be performed can be adjusted by means of the full utilization of historical environmental test data, the efficiency of the environmental test can be improved, and the costs of the test can be reduced. The environmental test plan design method includes the following steps that: the test pass rate and fault sensitivity index of each test item are determined according to the historical test data,wherein the test pass rate is used to characterize the capability of the test item in exciting a product fault, and the fault sensitivity index is used to characterize the efficiency of the test itemin discovering the product fault; the importance index of each test item is determined according to the test pass rate and the fault sensitivity index; and the environmental test plan of a product tobe tested is determined according to the importance index of each test item.

Description

technical field [0001] The invention relates to the field of environmental test data statistics, in particular to a method and device for designing an environmental test scheme. Background technique [0002] Environmental testing is an activity carried out to ensure that the product maintains functional reliability in all environments expected to be used, transported or stored during the specified life, and is to expose the product to natural or artificial environmental conditions. , to evaluate the performance of the product under the environmental conditions of actual use, transportation and storage, and analyze the degree of influence of environmental factors and its mechanism of action. [0003] With the in-depth development of product environmental tests, the rational use and analysis of a large amount of data obtained from the tests is becoming more and more important. Collecting various environmental test data in a planned and purposeful way and using them can help te...
