在工业生产中,常需对被加工的产品进行长度测量。如轧板机就必须时常测量被轧过之后板材的长度,以确定其是否合格。从而决定是否需要复轧。其它象原材料的下料、剪裁等等,也都需要测长。在实际上,需测长的物体可能是静止的,亦可能是运动的。本文只想就应用晶体管脉冲数字电路对运动物体长度的测量问题,作一初步探讨。
In industrial production, it is often necessary to measure the length of the product being processed. Such as rolling machine must always measure the length of the plate after being rolled to determine its eligibility. To decide whether the need for rolling. Other raw materials such as cutting, cutting, etc., also need to measure length. In fact, the length of the object to be measured may be static, it may be moving. This article only wants to apply the transistor pulse digital circuit measurement of the length of moving objects, make a preliminary discussion.
