<p>随着天气越来越凉,就需要很多控温场景,比如烧水,烘脚器,电热毯,孵化器.一般传统的控制采用档位调节或者通过温控开关来调节的,带来的体验很差,如果能控制在某一个温度,就能有很好的体验,PID温控器的想法就由此而来的,能实现开环PWM控制也能实现闭环控制.</p>

<p>本系统采用先进的ESP-12F模块作为核心控制单元,搭配NTC热敏电阻进行精确温度检测。通过高精度的24位ADC芯片将电压信号传输至ESP-12F模块,实现对温度数据的精准计算与处理。在设计过程中,特别注重模拟地与数字地之间的隔离,以确保采集到的温度信号更加稳定可靠。此外,TL431芯片被选用为基准电压源,进一步提升了系统的测量精度和稳定性。</p>
<p><span style="font-size: 14px;"><strong>1,温度采集</strong></span></p>
<p>测量温度选择NTC热敏电阻(型号是MF58 100K 1%精度 B值3950)</p>
<p>NTC热敏电阻是一种传感器电阻,其电阻值随着温度的升高而减小。 NTC热敏电阻,也称为负温度系数热敏电阻,是一种广泛用于各种电子元件中的传感器电阻.</p>
<p>为什么选择玻璃封装的,因为玻璃封装的NTC热敏电阻具有高稳定性和可靠性,能够在恶劣环境下使用.主要还是考虑在100度以上的情况使用.一般的3D打印的挤出头和热床也都是选用玻封的NTC热电阻.</p>
<p> </p>
<p><img src="//image.lceda.cn/pullimage/wBHCs84l4Ev8wcQw1M0LwlEjMZvXTnXJvE7cO0oR.png"></p>
<p>测量电路是选用cs1237 24位ADC芯片读取NTC电阻的电压值,从而求出电阻值,通过公式算出温度值.</p>
<p> </p>
<p>NTC热敏电阻的计算公式有Steinhart-Hart方程和B值法两种方法,本项目采用的B值方法:</p>
<p> </p>
<p>Rt = R*EXP(B*(1/T1-1/T2))<br>T1 =1/(ln(Rt/R)/B+1/T2)</p>
<p><br>这里T1和T2指的是K度即开尔文温度,K度=273.15(绝对温度)+摄氏度;其中T2=(273.15+25)<br>Rt 是热敏电阻在T1温度下的阻值;<br>R是热敏电阻在T2常温下的标称阻值;<br>B值是热敏电阻的重要参数;<br>EXP是e的n次方</p>

<p><span style="font-size: 14px;"><strong>2,控制输出</strong></span></p>
<p>单片机输出PWM控制信号,控制一个固态,来控制负载加热,从而调节温度.</p>
<p>由于控制的的是单相220v交流电,选取过零型固态继电器(卖基本都是过零型的),</p>
<p> </p>
<p>固态继电器分 过零型和随机型</p>
<p>分类主要通过触发信号分类的</p>
<p>过零触发:过零触发在交流电的正负半周过零点时触发可控硅,通过改变导通周波数来调节输出平均功率,实现负载功率的调节。这种方式输出波形为正弦波,但易出现低频干扰和闪烁现象。<br>移相触发:移相触发通过改变可控硅导通角的大小来控制输出功率或电压,输出波形被“斩”了一截,导致波形发生畸变,可能产生电磁波干扰。</p>
