几乎全部的工业控制系统中,都要求有定时控制。二汽车身厂驾驶室油漆烘干炉的定时控制任务是:每天按预定的时间(T_o)分为12段不同的时间(T_1～T_(12))控制通风电机、排风电机、恒温器和调温器等十几台设备,除厂休日和节假日不控制外,全年不停机,以实现无人控制。本文介绍的是用我们研制的PC-64型微机实现多台设备的定时自动控制,对于其它用途的控制系统也可以借鉴应用。
Almost all of the industrial control systems require timed controls. Two-car body factory cab paint drying oven timing control tasks are: daily scheduled time (T_o) is divided into 12 different time (T_1 ~ T_ (12)) control of the ventilation motor, exhaust motor, thermostat and Thermostat and other equipment more than a dozen, in addition to factory holidays and holidays do not control, non-stop throughout the year, in order to achieve unmanned control. This article describes the use of PC-64 computer developed by us to achieve the timing of multiple devices automatically controlled for other purposes, the control system can also learn from.
