Computer Control And Test Technology Of The Relay Electric Life Testing On Vehicles

The relay is a kind of auto control apparatus, which is acted with the special input signal,and the relay is widely used in many kinds of control systems.the relay test is the main means of testing the realy's quality.In all test,the electric life is one of the most important test.Commonly,the the use life of relay includes the mechanism life and the electric life,but the electric life is one level higher than the mechanism lift in quantity class.So the elctric life decides the use life.According to the environment of using the car relay,we conclude the condition of switch-on and switch-off of the relay,and make the computer test and control equipment.The theme introduces the simulative load and the design of the equipment hardware. We introduce in detail the circuit current and voltage when the relay is switch-on and switch-off,and make the software in DOS and WINDOWS.The equipment can dynamic shows the wave of the current and voltage when the relay is switch-on and switch-off.Moreover,the theme introduces the theory of Fault Tree.We model the fault of products with the RELEX software,thus the equipment has some primary intelligent.
