專題摘要翻譯成英文

  本專題是由AT89C51、CD4584、紅外線發射二極體、光電電晶體、LCD…等等。所組成的紅外線測速基本電路。

  本專題的目的是想藉由簡單的紅外線發射與接收,來了解基本測速器原理以及功能。

  為了達到以上目的,本專題是由單晶片89C51為主,利用兩組紅外線發射二極體與光電晶體來偵測物體經過的訊號,計算此訊號在兩組感測迴路上的訊號時間差即可得到時速。此訊號經由計算所得速率,即為其物體之時速。

  紅外線現在也有許多其他用途,將不單單只是當遙控器、選台器或是汽車鑰匙,就如同本專題的紅外線測速器,啟發更多創意與應用。

    The present topic is subject to a circuit of measuring speed by infrared radiation circuit composed of a AT89C51, CD4584, infrared light emitting diode, optoelectronic transistor and liquid crystal display.

    The present topic is purposed to realize basic principles and functions of speed measuring apparatus.

    In order to achieve the abovementioned purpose, the present topic mainly comprises a 89C51 chip, which detectes signals of a passing through object by two set of infrared light emitting diode and optoelectronic transistor and calculates time difference of two signals generated by the two sensitive circuits which sensing the signal of object. The signals are calculated to obtain the speed of the object.

    Infrared light not only can be applied to the speed measuring apparatus of the present topic, but also can be applied to remote controller, television remote controller and car remote key. It further can inspire creative ideas and applications more than this.
