Abstract

The invention provides an unattended reliability test device and system. The unattended reliability test device comprises an embedded processing module, a display screen, a power supply module, a front panel and a rear panel aviation plug interface, and commercial power enters the test device through the rear panel aviation plug interface. The display screen is connected with the embedded processing module; the rear panel aviation plug interface is connected with the embedded processing module through a cable; the embedded processing module completes output of a voltage regulation control signal and a relay control signal set by a program and tests a serial port, a network, a USB and a CAN port of a tested device by running a test program. The front panel comprises a main power switch, anindicator light and a buzzer, the main power switch is connected between the mains supply input and the power module, and the indicator light and the buzzer are both connected into the embedded processing module. Unattended operation can be achieved in the whole reliability test process, a large number of human resources are saved, meanwhile, human factors in the test process are reduced, and thetest accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of reliability testing, in particular to an unattended reliability testing device and system. In particular, it relates to an unattended military computer reliability testing device. Background technique [0002] In the development and production of military computers, it is necessary to verify or assess product reliability indicators. According to GJB requirements, the reliability test generally adopts multi-stress comprehensive test, and the test process generally adopts means of applying temperature stress, electrical stress, mechanical stress and humidity stress to the tested sample to accelerate product aging. The test time ranges from hundreds of hours to thousands of hours. There are a large number of voltage regulation, switching on and off, and intermediate test points in the process, and the operation time is scattered. Generally, it is necessary to arrange for 24-hour monitoring by test personnel...
