Embodiment Construction

[0042] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0043] Such as Figure 1 to Figure 4 As shown, the present invention provides a remote reliability life verification test system, which includes:

[0044] An environmental test chamber 3 with several test samples 4 inside.

[0045] A test computer 2. The test computer 2 has a built-in environmental operation control module for monitoring the environmental operation conditions of the environmental test chamber 3, and an automatic test module for simulating user operations on all test samples 4.

[0046] The automatic testing module can be implemented using programming software modules in the prior art. For example, Labwindows is programmed to realize the control of the tested samples. You can set the code box first in Lab Windows, generate function functions, and then call the function...

Abstract

The invention discloses a remote reliability lifetime verification and test system, and a method thereof. The system comprises an environmental test chamber in which a plurality of test samples are arranged and a computer used for testing, wherein the environmental test chamber is connected with the computer used for testing through an USB concentrator, and the environmental test chamber comprises a controllable control interface. The test system further comprises a remote control computer for directly logging on to the computer used for testing to perform remote monitoring on the test samples. An environment operation control module and an automatic test module are arranged in the computer used for testing. An operational serial port is arranged in the environmental test chamber for receiving environmental condition operation control instructions sent from the computer used for testing. Based on the above-mentioned test system, the invention further provides a remote reliability lifetime verification and test method. By adopting the system and the method provided in the invention, automatic tests can be realized, test status is monitored in real time through remote control, troubleshooting is performed at any time, and mean time between failures of the test samples is accurately calculated.

Description

technical field [0001] The invention relates to a test system and its method, in particular to a remote reliability life verification test system and its method. Background technique [0002] With the development of science and technology, the functions of similar products are becoming more and more perfect, the competition is becoming more and more fierce, and customers have higher and higher requirements for product reliability. At present, in the product development stage, in order to know the mean time between failures of the product and verify whether the reliability of the product meets the design requirements, the reliability life verification of the product must be carried out. [0003] The mean time between failures of the product, the target value is generally based on the customer's requirements, or estimated according to the MIL STD standard. For example: Some companies have an MTBF of ten years for industrial applications. Usually based on the target value, co...
