摘　　要：本显示仪装置是利用磁针在地球磁场中能产生方向指示,用红外光敏器件作为方向信号采集器件,并使之变为数字信号,经单片机的编程控制和处理,在8×8点阵LED管上以字母(E—东,S—南,W—西,E—北)直观地随时反映出机动车的行驶方向。由于本装置是用8×8点阵管LED显示屏显示方向,日夜显示机动车的行驶方向都非常直观。这将是机动车准确安全行驶的得力助手。The principle of the equipment is that the magnetic needle can point out the direction of the magnetic field of the earth.The infrared detector is used as the device collecting the direction signals and changing them into digital signals.The signals are processed by a single chip directly,and the timing unit shows the direction of motor vehicles with letters(E-east,S-south,W-west,N-north)on the8×8lattice tube.It is quite intuitive to show the direction of motor vehicles day and night,so it is helpful for safe and accurate travel of motor vehicles.
