為了提高傳統(tǒng)溫度控制系統(tǒng)的性能,將PID控制理論與嵌入式系統(tǒng)相結(jié)合,采用瑞薩電子公司的H8S/2166作為核心處理器,AD公司的AD7705以及熱敏電阻溫度傳感器作為溫度檢測單元,利用4×6小鍵盤、LCD顯示器和S1D13305液晶控制器達到良好的人機交互,設(shè)計出了一個應用于化工領(lǐng)域的嵌入式實時溫度控制系統(tǒng)。相比于傳統(tǒng)溫度控制系統(tǒng),該系統(tǒng)提供了更強的計算能力和可擴展能力,采用增量PID控制算法實現(xiàn)復雜控制。通過實驗,該系統(tǒng)能達到0.1 ℃的溫度控制精度以及小于120 s的溫度穩(wěn)定時間。 Abstract: In order to improve the performance of conventional temperature control system, combining PID control theory with embedded systems, using the Renesas Electronics Corp. H8S/2166 micro-controller as a core processors, AD7705 and thermistor temperature sensor as a temperature detection unit and 4×6 small keyboard, LCD and S1D13305 LCD controller as a good human-computer interaction, this paper designed an embedded real-time temperature control system which is applied in chemical industry. Compared with conventional temperature control system, this system provides more computing power and extensibility, and adopts PID control algorithm for complex control. Through the experiment, the system can reach temperature control accuracy of 0.1 ℃ and temperature stabilization time of less than 120 seconds.
