摘要
传统的温度控制系统是以热敏电阻为温度传感器件,辅以风冷或水冷来达到目的的,存在体积大,噪音大且精度有限的缺点。介绍了利用数字温度传感器(DS18B20)与DSP芯片(TMS320F2812)组成的温度测量系统,结合模糊PID算法(Fuzzy-PID),利用DSP的脉宽调制控制通过半导体制冷器的电流大小,达到温度控制的效果,体积小且精度达到0.1℃。给出DSP与DS18B20的接线图,并且介绍了利用CCS(代码编辑工作室)进行软件开发。该系统已经运用在LD温度控制方面,取得了很好的效果。
Traditional temperature control system took thermal resistance as the temperature sensor,combined with air-cooled or water to achieve the purpose,size large,noisy and the accuracy is limited.The temperature measurement system composed of digital temperature sensor（DS18B20） and the DSP（TMS320F2812）,the DSP pulse-width modulation is used to control the current of the TEC combined with fuzzy PID algorithm（Fuzzy-PID）,to achieve the effect of temperature control,small size and 0.1 accuracy.The wiring diagram of DSP and DS18B20,the use of CCS（code editing studio） for software development are introduced.The system has been used in the LD temperature control,and has gained very good results.
