Reliability Test Device Of Relays And Central Control System

Relay is one of the key elements used in automation control system, remote control and measure system, and communication system. It has been widely used in aviation, spaceflight, electron, communication, engine etc equip. In the reign of country economy, and especially in the stress military project of our country, relay is very important. Reliability of relay will straightly effect the development of those domain. The study of reliability of miniature relay is an important task in the study domain of electric reliability. The traditional reliability testing device of relay can only confirm the. fault has taken placed in witch sample, and can not save the info of faults (abate types, abate times, abate time etc) and the capacity of memory is small. The old traditional device can not fulfill the request of current test.This paper is concerned with a recently developed reliability test device of relays and a focus control system. It can overcome the bug of the traditional testing device in a large scale. This paper gives a full-scale discuss to the software and hardware design of the AC reliability testing device and the DC reliability testing device. In the course of hardware designing, this paper gives a discuss from choosing the mainframe and collection card to the construct of the whole testing device. In the course of software designing, this paper gives a primary discuss from choosing the programming language to the structure of application and to the shape of the interface etc. Using the VC internet programming technique realized the focus control for several those AC reliability testing device and the DC reliability testing device. In the last, this paper analyzes the error caused by some factors.Developing the reliability testing device of relay and focus control system will take large function for perfecting the design of relay or improve the reliability of relay.
