Relay-type stand-alone accelerated storage testing device and method

Abstract

The invention discloses a relay-type stand-alone accelerated storage testing device, and the device is used for the accelerated storage testing of a plurality of relay-type stand-alone units, wherein each relay-type stand-alone unit comprises a plurality of input / output terminals. The device comprises a plurality of constant temperature and constant humidity testing boxes, an intelligent alarm system, a terminal switching and control circuit, a contact resistance measurement circuit, a time parameter measurement circuit, and an upper computer system. The upper computer system is connected with the terminal switching and control circuit and the time parameter measurement circuit. The upper computer system sends a parameter setting command, a system self-testing command and a testing starting command to the terminal switching and control circuit and the time parameter measurement circuit. The terminal switching and control circuit is connected between the plurality of relay-type stand-alone units and the contact resistance measurement circuit. The contact resistance measurement circuit is used for testing the contact resistance value at each input / output terminal of the relay-type stand-alone units and transmitting the measured contact resistance values to the upper computer system.

Description

technical field [0001] The invention relates to the technical field of relay performance testing, in particular to a testing device and testing method for a single-machine accelerated storage test of relays. Background technique [0002] The relay type stand-alone is usually a type of electromechanical product composed of discrete devices such as relays, resistors, and diodes. It is widely used in defense weaponry systems such as missiles and rockets to complete functions such as signal transmission and system power supply and distribution. It is reliable. The reliability directly affects the reliability of the entire national defense weapon system. [0003] Modern weapons and equipment are stored in a long-term storage environment. Under the combined effects of temperature, humidity, vibration, and electrical stress, changes in their life and function indicators directly affect whether the missile can work reliably. Therefore, the research on the storage reliability of sin...

AI Technical Summary

Problems solved by technology

[0004] At present, there has been some research on the storage test of relays at home and abroad, but there is still little research on relay single-unit systems. There is no special test system to monitor the storage degradation parameters of a single unit. Some current accelerated test methods are not perfect enough. , the reliability evaluation of a stand-alone machine is still in its infancy
