Problems solved by technology

According to the results of the temperature cycle stress screening test on the wireless transmission device for a period of time, it was found that the problems exposed by the test piece during the process were mostly low-temperature occasional problems. Due to the imperfect monitoring methods in the early stage, it took many detours, resulting in the failure of the product. The stagnation period is long, and the maintenance cost after delivery increases significantly
At the same time, the industry does not have a set of real-time monitoring application systems and methods for environmental stress screening

Abstract

The invention discloses a wireless transmission device diagnosis system based on an environmental stress screening test, and the system comprises: a power supply unit which is used for supplying powerto a tested sample; a high-temperature and low-temperature cyclic aging box which is used for providing a test stress screening environment for the tested sample; a control unit which is connected with the power supply unit and used for monitoring the voltage or / and current state of the power supply unit in real time, is connected with the aging box and used for monitoring the real-time temperature state and aging period of the aging box, and is connected with the tested sample and used for monitoring the state of the tested sample. The invention also discloses a diagnosis method which comprises the following steps: S01, configuring the IP of each tested sample, and configuring aging parameters; s02, opening the high-low temperature cycle aging box, performing timing, and monitoring the state data of the high-low temperature cycle aging box, the power supply unit and the tested sample in real time; and S03, performing operation processing on the state data in the step S02 to obtain anaging report. The system and the method have the advantages of simplicity and convenience in operation, high universality and the like.

Description

technical field [0001] The invention mainly relates to the technical field of temperature testing equipment, in particular to a diagnostic system and method of a wireless transmission device based on an environmental stress screening test. Background technique [0002] Environmental Stress Screening (ESS) technology has been widely and deeply applied in the production process of the rail transit industry, which has played a good role in eliminating early product failures. According to the results of the temperature cycle stress screening test on the wireless transmission device for a period of time, it was found that the problems exposed by the test piece during the process were mostly low-temperature occasional problems. Due to the imperfect monitoring methods in the early stage, it took many detours, resulting in the failure of the product. The stagnation period is long, and the maintenance cost after delivery increases significantly. At the same time, there is no establi...
