Design and Applications of the Circuit of Keyboard Display in Detecting Axle’s Temperature System

  •  Guilin Lu    


The technology of detecting axle’s temperature with infrared rays is a new kind of scientific product which plays an important part in the indemnity system of railway rolling stock, The circuit of keyboard and display is a man-machine interactive technology,which is composed of Chip 8279,LED digital display and correlative instruments.Coordinated by Chip 8279,LED digital display perform to read keyboard numerical values and display memory address ; power self-check is accomplished by the Voltage compare device in the circuit;the calendar clock chip 5832 makes the clock display possible. Experimental results accomplished with parameter show that the design of hardware and software is applicable to Infrared Rays System
