| 摘 要： | 为了提高传统温度控制系统的性能,将PID控制理论与嵌入式系统相结合,采用瑞萨电子公司的H8S/2166作为核心处理器,AD公司的AD7705以及热敏电阻温度传感器作为温度检测单元,利用4×6小键盘、LCD显示器和S1D13305液晶控制器达到良好的人机交互,设计出了一个应用于化工领域的嵌入式实时温度控制系统。相比于传统温度控制系统,该系统提供了更强的计算能力和可扩展能力,采用增量PID控制算法实现复杂控制。通过实验,该系统能达到0.1℃的温度控制精度以及小于120 s的温度稳定时间。

| 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. |
