所谓定时控制器就是按照预定的程序控制执行机构。完成一系列操作。它可广泛应用于工业自动化生产的某些操作过程。如化工厂反应罐的升温、降温、添料、冷却;电镀车间的镀件、取件、清洗等;也可用于学校和企事业单位作息的自动打铃以及各种家用电器的定时启闭等。根据不同的原理,采用不同的电路,选用不同的元器件,均可实现上述功能。本文介绍的时控器采用大规模集成电路EPROM完成译码和动态扫描显示,用CMOS RAM作为操作内容的存贮单元,故系统具有电路简单,操作方便,抗干扰能力强等特点,并真正做到了“多路”、“多点”。一、功能特点 The so-called timing controller is in accordance with the predetermined program control actuator. Complete a series of operations. It can be used in a wide range of industrial automation processes. Such as chemical plant reaction tank temperature, cooling, Tim material, cooling; electroplating workshop plating, pick-up, cleaning, etc .; can also be used for school and business units for automatic ringing bell and a variety of household appliances, such as the timing of opening and closing . According to different principles, using different circuits, the use of different components, can achieve these functions. This article describes the use of large-scale integrated circuit EPROM complete decoding and dynamic scanning display, with the use of CMOS RAM as the operating content of the storage unit, so the system has a simple circuit, easy operation, anti-interference ability and so on, and truly To the “multiple”, “more.” First, the functional characteristics
