溫度伺服控制系統(tǒng)是數(shù)碼變溫空調的一個重要的子系統(tǒng),是數(shù)碼變溫空調的執(zhí)行機構。
本文根據(jù)數(shù)碼變溫空調的工作原理,提出了一種基于ARM 微控制器的全數(shù)字式溫度伺服控制系統(tǒng)。溫度伺服系統(tǒng)硬件電路是以基于ARM 的數(shù)字溫度控制器為核心,通過單線總線數(shù)字溫度傳感器DS1820 對室內外溫度進行采樣,并使用液晶模塊對溫度伺服系統(tǒng)的各個運行參數(shù)進行實時顯示和分析。采用通用的模塊化設計方式,編寫了溫度伺服系統(tǒng)調速程序, 并且使用C 語言對程序進行了實現(xiàn)。

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.
