基于微控制器的数字式温度伺服控制系统

温度伺服控制系统是数码变温空调的一个重要的子系统,是数码变温空调的执行机构。
本文根据数码变温空调的工作原理,提出了一种基于ARM 微控制器的全数字式温度伺服控制系统。温度伺服系统硬件电路是以基于ARM 的数字温度控制器为核心,通过单线总线数字温度传感器DS1820 对室内外温度进行采样,并使用液晶模块对温度伺服系统的各个运行参数进行实时显示和分析。采用通用的模块化设计方式,编写了温度伺服系统调速程序, 并且使用C 语言对程序进行了实现。

Abstract: Temperature servo system used as execute outfit is a subsystem of temperature-adjustedair-conditioner. Based on the principle of temperature-adjusted air-conditioner, a kind of digital servo control system with ARM microchip LPC2214 as its core is presented. The hardware circuit of temperature servo system uses digital temperature controller with LPC2214 as its core, the system samples indoor and outdoor temperature signals with temperature sensor DS 1820, and displays all kinds of parameters with LCD module. On the basis of characteristic of temperature servo control system, a kind of control arithmetic based on tri-loop model with indoor temperature, rotate speed and current has been presented. The speed-adjusted program of temperature servo control system has been written with C language.
