一种可编程电子式凸轮开关控制器的设计

长期以来，使用凸轮和限位开关的机械式凸轮在自动化生产机械中已得到了广泛的应用。但是，由于机械元器件在安装和运行时的局限性，便决定了机械式凸轮存在控制精度低、可靠性差、角度调整及开关更换不方便等缺点。为此，根据机械凸轮原理设计了采用双单片机结构的电子式凸轮开关控制器，对脉冲编码输入进行数据采集及处理，与PLC连接使用，从而完成对自动生产中的往复循环过程控制。

Design on Controller of Programmable Electronic Cam Switch

The design of electronic cam switch introduced in this paper is based on the theory of mechanic cam. It contains a double- microprocessor structure as central component and collects and treats the pulses or encodin gg for the input data. The controller is linked with PLC and put into use to complete circling control for auto-ma nufacture.
