【摘要】 本文介绍一个应用可编程序控制器对温度进行控制的系统.它采用热电偶作为温度传感器.通过AD变换,由可编程序控制器进行数据处理,获得温度控制信号,使控制灵活、可靠.再通过DA变换,由达林顿管功放控制加热器,达到温度控制要求.更多还原

【Abstract】 This paper introduces a apply of the programmable Logic controller on controller of temperature. It uses temperature Sensor of thermocouple. Processing AD transfer, data have been processed by the Programmable Logic controller, it obtains control signal of Temperature, it has flexibility and reliability of control. Again processing DA transfer, heater is controlled by power tube of Darlinton. Control requirement of temperature is had.更多还原
