摘　　要：智能(温度)控制无论在工业控制领域还是消费电子领域应用都非常广泛,如工业控制中锅炉,加热炉的控制,消费电子领域的热水器,饮水机的控制,内部都涉及到温度控制。而且目前控制算法的丰富为温度控制提供了便利条件,应用较为普遍地有比例积分微分PID控制,模糊控制等。本设计系统以51单片机为核心,系统的主要内容是使用单片机系统进行温度实时采集与控制。系统主要功能:内置PID控制算法,模拟输入输出及RS232通讯网络。采用MODBUS通信协议进行远程控制及参数设置。Intelligent temperature control are very wide whatever in industry control or consumer electronics applications, such as industrial boiler, reheating furnace in the control of the consumer electronics field control, water heater, water dispenser, internal control is designed to control temperature. The control algorithm provides a convenient conditions for temperature control, which are widely used in proportion integral differential PID control, the fuzzy control, etc. The design of the system to 51 SCC as the core, the main content of the system is the use of SCM system for real-time data acquisition and control temperature. System main functions： built-in PID control algorithm, [JP3]the analog input output RS232 communication network. MODBUS communication agreement by remote control and parameter.
