该温度控制系统以STC89C52单片机为核心,采用DS18B20数字温度传感器采集温度,并以PWM形式输出,确保温度输出的稳定,再结合PID闭环控制,使系统能够更稳定地运行。先利用Proteus软件结合Keil软件仿真,再用STC89C52单片机进行实测,从而进一步验证了设计的可靠性和准确性,所控制温度的精度能达到±1℃范围之内。该系统具有灵活性强、电路简单、可靠性高、易于操作等优点,能够实现对温度的稳定控制。
The temperature control system to STC89C52 microcontroller as the core, the use of DS18B20 digital temperature sensor temperature acquisition and PWM output, to ensure the stability of the temperature output, combined with PID closed-loop control, the system can be more stable operation. The first use of Proteus software combined with Keil software simulation, and then STC89C52 microcontroller measured to further verify the reliability and accuracy of the design, the temperature control accuracy can reach ± 1 ℃ range. The system has the advantages of strong flexibility, simple circuit, high reliability, easy operation and the like, and can achieve stable control of temperature.
