Design of a High Precision Temperature Control System Based on ARM+FPGA

温度控制系统在工业、农业、医药等领域应用广泛,实际应用现场情况复杂。要满足系统对温度控制的精确性和实时性,采用传统的设计方法很难实现。本文提出一种基于ARM+FPGA的温度自动控制系统,该系统采用模块化结构,具有控制精度高、操作方便灵活、实时性强和易于扩展等特点,集温度采集、信号处理、键盘参数输入、LED显示于一体。采用闭环神经网络控制模型,分段PID控制算法,高速A/D、D/A转换,配合功能强大的嵌入式微处理器,以达到温度控制的精确度和自适应性。

The temperature control system is widely used in industry,agriculture,medicine and other fields,and the applied conditions are complex.The traditional methods is unsatisfied to meet the precision and real-time performance for temperature control.This paper presents an automatic temperature control system based on ARM＋FPGA.This system uses the modular structure with the obvious characters of high control accuracy,flexible operations,strong real-time and easy to extend,formed by temperature sample,signal processing,keyboard input and LED display.We use closed loop neural network control model,PID control algorithm,high-speed A / D,D / A conversion and powerful embedded microprocessor to achieve the precision and adaptation of temperature controlled.
