TCRT5000_红外反射式光电传感器_反射型光电开关_光电对管_寻迹小车专用

光电传感器选型要素有哪些？①结构类型：放大器分离型、放大器内藏型等②检测方式：对射型、回归反射型、扩散反射型等③工作电源：直流、交流、交直流通用（E3JK/E3JM，E3G系列）④检测距离：详见各产品样本资料⑤检测物体：外形、大小、颜色⑥控制输出：晶体管输出、继电器输出等⑦连接方式：导线引出型、接插件式⑧其它功能：延时功能、计数器功能等⑨附件：狭缝、反射板、安装配件等驱动方式由于自激蜂鸣器是直流电压驱动的，不需要利用交流信号进行驱动，只需对驱动口输出驱动电平并通过三极管放大驱动电流就能使蜂鸣器发出声音，很简单，这里就不对自激蜂鸣器进行说明了。

这里只对必须用1/2duty 的方波信号进行驱动的他激蜂鸣器进行说明。

单片机驱动他激蜂鸣器的方式有两种：一种是PWM 输出口直接驱动，另一种是利用I/O 定时翻转电平产生驱动波形对蜂鸣器进行驱动。

PWM 输出口直接驱动是利用PWM 输出口本身可以输出一定的方波来直接驱动蜂鸣器。

在单片机的软件设置中有几个系统寄存器是用来设置PWM 口的输出的，可以设置占空比、周期等等，通过设置这些寄存器产生符合蜂鸣器要求的频率的波形之后，只要打开PWM 输出，PWM 输出口就能输出该频率的方波，这个时候利用这个波形就可以驱动蜂鸣器了。

比如频率为2000Hz 的蜂鸣器的驱动，可以知道周期为500μs，这样只需要把PWM 的周期设置为500μs，占空比电平设置为250μs，就能产生一个频率为2000Hz 的方波，通过这个方波再利用三极管就可以去驱动这个蜂鸣器了。

而利用I/O 定时翻转电平来产生驱动波形的方式会比较麻烦一点，必须利用定时器来做定时，通过定时翻转电平产生符合蜂鸣器要求的频率的波形，这个波形就可以用来驱动蜂鸣器了。

比如为2500Hz 的蜂鸣器的驱动，可以知道周期为400μs，这样只需要驱动蜂鸣器的I/O 口每200μs 翻转一次电平就可以产生一个频率为2500Hz，占空比为1/2duty 的方波，再通过三极管放大就可以驱动这个蜂鸣器了。

基于TCRT5000红外传感器模块的设计报告.doc

电子创新设计模块制作设计报告名称：基于TCRT5000的循迹模块学院：机电工程学院专业：应用电子技术班级：09应电（2）班设计者：林志坚指导老师：玉宁杨青勇2011年6月一、硬件设计及说明1、原理图设计如下：图一原理电路作用原理：采用5V供电，TCRT5000传感器采用高射功率红外光电二极管和高灵敏度光电晶体管组成。

红外光电二极管发出红外光，当红外光反射回来被高灵敏度光电晶体管接收，则光电晶体管处于导通状态，输出高电平信号；当红外光没有反射回来，则光电晶体管处于高阻抗状态，输出低电平信号；输出信号经施密特电路整形，稳定可靠，且还有LED指示电路指示输出的状态，输出高电平时LED亮，低电平时灭。

2、PCB设计如下：图二PCB线路设计思路：板的大小为：10mmX40mm。

采用的是插件元件，降低了焊接难度，板的宽度只有10mm，这样使得该模块灵巧，在应用过程中更灵活。

二、主要元件介绍：1、TCRT5000：TCRT5000传感器采用高射功率红外光电二极管和高灵敏度光电晶体管组成。

红外光电二极管不断地反射出红外线，当发射出的红外线没有被反射回来或反射回来但强度不够大时，光敏三级管一直处于关断状态，输出低电平；当发射出的红外线被反射回来时，光敏三级管处于关闭状态，输出高电平。

2、CD40106CD40106由六个斯密特触发器电路组成。

每个电路均为在两输入端具有斯密特触发器功能的反相器。

触发器在信号的上升和下降沿的不同点开、关。

上升电压(V T+)和下降电压(V T-)之差定义为滞后电压。

三、测试过程：（1）外形尺寸：10mmX45mm；（2）工作电压：DC3V-5.5V；（3）检测距离：1mm-8mm适用，焦点距离为2.5mm;五、应用场合（1）电度表脉冲数据采样；（2）传真机碎纸机纸张检测；（3）障碍检测；（4）黑白线检测；六、注意事项：（1）使用时，光电传感器的前端面与被检测的工件或物体表面必须保持平行，这样光电传感器的转换效率最高；（2）光电传感器的前端面与反光板得距离保持在规定的范围内才能正常工作；（3）光电传感器长时间工作时红外接收管的最大工作电流不应超过250uA; （4）焊接改装传感器时，光电传感器的引脚根部与焊接点的最小距离不得小于5mm且焊接时间尽可能短，否则易损坏管芯或引起管芯性能的变化；七、总结经过这次模块的制作，我们学习了传感器和施密特触发器的知识及其相关应用，深入了解了TCRT5000红外传感器和CD40106的原理及应用，同时，在电路板的制作过程中，我们熟练了PCB的设计及制作电路板工艺。

电路图理解——精选推荐

巡线机器人参考电路图详细讲解——校机器人队队员前注：本来这部分介绍是在一期培训展示的，但是考虑到面试之后有不少的同学仍心存疑问，加之培训不可能每个组都会参加，因此提前进行讲解，之后会有其它电路方面的知识补充，本次介绍只涉及本次的参考电路图，对于其它的改良电路或者改进技巧暂不提出。

一、信息采集部分图1这是传感器部分更新电路的电路图。

1、TCRT5000图中的TCRT5000是组委会提供的参考巡线传感器，我们可以从网上找到它的pdf，下面我指出几个比较重要的参数：表格 1这是订购指南，12mm是它的典型检测距离，有时候也把它当做最大检测距离，但是实际使用并不局限在这距离内。

表格 2发射管最大参数，端电压最大5V,正向电流最大60mA，只需要注意这两点即可。

表格 3接收管最大参数，注意V CEO和V ECO即可，一般来说，接收管是不会坏的。

接下来就是它的典型参数，就是电气参数，这里需要注意它的测试环境，若是在最坏情况下测试的，使用时应作适当的修正。

表格 4发射管典型参数，正向测试环境是I F=60mA，我们发现这是最大值，因此使用时应小于这个值。

这个环境下正向电压的典型值是1.25V,我们设计电路时，应使分流电阻的电压大于VCC-1.25V，上图电路中是3.75V.表格 5接收管的典型参数，最后一项是无照电流，也叫暗电流，是指没有光照时光电三极管的漏电流。

其它两项的余量较大，暂时可以不予考虑。

图二是测试示意图，表明这些测试时在正对的情况下得到的，若是斜着摆放，需要重新考虑，不可拘泥。

图 2然后我们看电路设计原理。

首先是发射管的限流电阻。

刚才已经说过，发射电流最大60mA ，此时两端典型压降是1.25V,为了保证发射管不烧坏，同时有较大的发射功率（保证反射光的强度能够激发接收管）。

最小电阻是：5 1.2562.560V V mA-=Ω 最大电阻我们需要重另一方面考虑，请看下图：图 3由图可知，正向压降至少需要达到0.95V 时，二极管才会正常工作，我们用10mA 正向电流的地方计算电阻最大值。

tcrt5000

TCRT5000的应用电路见如4所示。

当检测到绿色地面时，由于反射率不高，Ic1太小，三极管T2截止而输出高电平。

当检测到白色地面时，由于反射率较高，Ic1较大，三极管T2饱和而输出低电平，从而实现了白线的检测。

555构成了施密特触发器，用于去除反射性光耦产生的噪声和波形的整形。

根据设计任务，悬挂物体要沿着黑线运行，采用反射式光电传感器进行探测。

光电传感器的硬件设计如图4.3.4所示。

电压比较器L M393的同相输入Ⅴin拉低，输出为低电平。

当检测到黑线时，接收管截止，同相输入Ⅴin为高，比较器输出为高电平。

本系统中四个传感器的OUT分别连接P1.0～P1.3。

在图4中，可调电阻R3可以调节比较器的门限电压，经示波器观察，输出波形相当规则，可以直接够单片机查询使用。

而且经试验验证给此电路供电的电池的压降较小。

因此我们选择此电路作为我们的传感器检测与调理电路。

模块原理和应用
电路原理图：
图 1 TCRT5000传感器模块电路原理图
传感器的红外发射二极管不断发射红外线，当发射出的红外线没有被反射回来或被反射回来但强度不够大时，光敏三极管一直处于关断状态，此时模块的输出端为低电平，指示二极管一直处于熄灭状态；被检测物体出现在检测范围内时，红外线被反射回来且强度足够大，光敏三极管饱和，此时模块的输出端为高电平，指示二极管被点亮。
