摘要
在食品加工过程中,温度控制是一极重要的控制环节,在温度过程控制中常出现超调、时滞而难于控制等特点.本文提出了一个简易可行的设计方案,并提供了硬件电路和软件框图.只要适当调节硬件和调整软件,便可以应用于任何食品焙烘过程的任何温度范围的控制,同时只要用一台微型计算机便可实现对多个食品加工温度或其他物理量的控制.
Temperature control is an important control link in food processing. The overshoot and delay often appear in the prbcess of temperature control and this is very difficult to control . In this paper a simple design trogramme has been given out,the hardware circuit and the sdftwire block diagram have been provided as well Only if it is regulated properly,can this design be used to control change of temperature in processing of any food cure. Meanwhile, only one single microcomnuter is required to implement the temperature control of several food prccses svstems or control of other physical quantities at the same time
