Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 As shown, the rail transit electronic veneer strengthening test method of the present embodiment includes the first comprehensive test combining low temperature and vibration, and specifically includes the following steps:

[0033] S01. First, determine each first comprehensive test point in the first comprehensive test, and each first comprehensive test point has a corresponding temperature value and vibration value;

[0034] S02. When the electronic single board is in a power-on state, maintain the first preset time at each first comprehensive test point, and perform an offline or online test on the electronic single board;

[0035] S03. After completing all the tests at the first comprehensive test point, place the electronic single board under the debugging environment conditions for offline testing.

[0036] The r...

Abstract

The invention discloses a rail transit electronic single board enhancement test method, which includes a first comprehensive test with combination of low temperature and vibration. The method concretely includes the following steps: S01, determining all first comprehensive test points in the first comprehensive test, wherein each first comprehensive test point has a corresponding temperature value and a corresponding vibration value; S02, when an electronic single board stays in a powered-on state, maintaining a first preset period of time for each first comprehensive test point, and testing the electronic single board on-line or off-line; and S03, after testing of all the first comprehensive test points is completed, placing the electronic single board in a debug environment to carry out an off-line test. The rail transit electronic single board enhancement test method has the advantage that the reliability of the electronic single board can be improved.

Description

technical field [0001] The invention mainly relates to the technical field of rail transit, in particular to a method for intensifying a rail transit electronic single board. Background technique [0002] Intensification test is a kind of reliability development test through accelerated stress. Its function is to make the product design more robust. The reliability is continuously improved, so that the environmental adaptability of the product is also improved. Although the current reliability test is a traditional general-purpose simulation test or reliability test, there is still a lack of specific and effective methods for intensified tests on electronic single boards in rail transit because of long test times, low efficiency, and high costs. Contents of the invention [0003] The technical problem to be solved by the present invention is that, aiming at the technical problems existing in the prior art, the present invention provides a method for strengthening the elec...
