Research Of Automatic Control Technique In Center And Medium Modulus Gear Ultrasonic Test

One kind of the most common mechanical drive in the machine is the gear drive, it is main form oftransmits the power and the movement.There is no pointed ultrasonic testing for center and small modulusgear since long ago.This article introduced the theory and status quo of ultrasonic testing,and primarilyresearched the control method of center and small modulus gear auto-examination system based onnumerical control.machine.According to the examination's characteristic,the overall plan of control systemhas been designed.The control card is centered at MCU ,which can control crack detector and dataacquisition card,as well as communicate with the industrial control computer has been developmented.Haschosen hardware and so on crack detector according to the system request.Designed the hardware electriccircuit according to the the method in this article, and used the assembly language to compile the softwareof control card.The control card uses the 89C52 microcomputer as controller, take the benchmarkfrequency source, phase-lock link and the timer precisely produced each kind of trigger pulse signal whichthe system needs.The antijamming question. of the system and control card has discussed.In the softwaredesign, mainly introduced the software development flow and the development tools, explain the demandanalysis and the resource distribution also.In various program module design has analyzed the masterroutine flow, the signal procedure and the interrupt routine, and elaborated the procedure monitoring fromthe software angle.
