布长记录仪电路及程序设计

To Design the Circuit and the Program of the Cloth Length Recorder

文中介绍印染车间流水线上的布长记录仪。采用 VCC、VDD 两个不同电源供电,以避免传感部分对空中电磁波所产生的感应引起对单片机电路的串扰。该布长记录仪性能可靠,构造简单,成本低。

In this article, the cloth length recorder used in the streamline of the print workshop which is designed by the writer is introduced. It uses two different power sources VCC, VDD to supply, in order to avoid interfering the singlechip circuit with the induction of the sensor section which is by the electromagnetic wave in the air. This cloth length recorder has a reliable property, a simple construction, and a low cost.
