亿光红外线接收头电路工作原理文章出处:广州市超毅电子有限公司亿光红外线接收头主要应用在机顶盒,红外遥控系统上,亿光代理商超毅电子讲解一下关于接收头的工作原理,从电路,PD晶片以及放大电路中分析亿光红外线接收头的工作原理。
首先大家来看一下亿光红外线接收头的系统框架:从PD(光电二极管及其偏置电路上分析亿光红外线接收头的工作原理:PD晶片感应信号红外光,将接收到的光信号转换成电流信号。
红外线接收头的偏置电路向提供PD提供合理的方向偏置条件;对信号起可变阻抗的功效,消除干扰信号;将有大部分用信号传送到后级放大器。
TA(阻抗变换放大电路在PD和后级放大器之间起阻抗转换作用,将电流信号变换成电压信号;分离感应电流的交流和直流分量。
红外线接收头CGA(可控增益放大电路提供整个模块的主要增益(50-80dB;可以接受指令改变增益;受控于AGC(自动增益控制。
BF(带通滤波器根据信号的频域特征来消除干扰的手段,能消除来自于各种干扰源的干扰信号;通频带宽度为4KHz;优值为7-10以上;中心频率在IC出厂时调好,有多种中心频率供选用。
AGC(自动增益控制电路根据信号的时域特征来消除干扰的手段,能消除各种不同时间特征参数的干扰信号;基于脉冲簇时长和脉冲簇之间的间隙时间等参数,判别有用信号或干扰信号;不同型号的IC,对时间参数的判别依据不同;遇到干扰时,将CGA的增益调到最小,不让干扰信号通过;不会影响有用信号的接收;在黑暗的环境下,AGC将CGA的增益控制到很大的数值,但要保证没有自发的输出。
以上就是亿光红外线接收头的工作原理,根据各电路分析的红外线接收头接收头,亿光代理商超毅电子主推红外线接收头IRM3638系列,如果对于红外线接收头的技术咨询,可直接咨询客服,我们会为您提供技术支持以及应用资料。

智能小车红外循迹巡线传感器原理与应用电路2011-09-27 11:24智能小车是指由单片机控制的,可以修改程序的,在程序的控制下,能够自由移动,自动完成特定功能的小车。
它集计算机技术,软件编程,自动控制,传感器技术,机械结构于一体,是学习信息技术,机器人的最佳载体。
小车循迹指的是小车在白色地板上循黑线行走,通常采取的方法是红外探测法。
也可用CCD,CMOS 摄像头方案,光电优点:1.电路设计相对简单2.检测信息速度快3.成本低缺点:1.道路参数检测精度低、种类少2.检测距离短3.耗电量大4、容易受外界光线干扰摄像头优点:1.检测前瞻距离远2.检测范围宽3.检测道路参数多缺点:1.电路相对设计复杂2.检测信息更新速度慢3.软件处理数据较多红外探测法,即利用红外线在不同颜色的物体表面具有不同的反射强度的特点,在小车行驶过程中不断地向地面发射红外光,当红外光遇到白色纸质地板时发生漫反射,反射光被装在小车上的接收管接收;如果遇到黑线则红外光被吸收,小车上的接收管接收不到红外光。
单片机就是否收到反射回来的红外光为依据来确定黑线的位置和小车的行走路线。
常用的红外探测元件有红外发光管,红外接收管,红外接收头,一体化红外发射接收管。
红外线是不可见光线。
所有高于绝对零度(-273.15℃)的物质都可以产生红外线。
人的眼睛能看到的可见光按波长从长到短排列,依次为红、橙、黄、绿、青、蓝、紫。
其中红光的波长范围为0.62~0.76μm;紫光的波长范围为0.38~0.46μm。
比紫光波长还短的光叫紫外线,比红光波长还长的光叫红外线。
红外发光二极管:外形和普通发光二极管LED相似,发出红外光。
管压降约1.4v,工作电流一般小于20mA。
为了适应不同的工作电压,回路中常常串有限流电阻。
红外线发射管有三个常用的波段,850NM、875NM、940NM。
根据波长的特性运用的产品也有很大的差异,850NM波长的主要用于红外线监控设备,875NM主要用于医疗设备,940NM波段的主要用于红外线控制设备。

红外线遥控接收头在3D眼镜上的应用
超毅电子蒋文霞
随着3D电视的普及,3D眼镜也越来越多,目前主流的“主动式快门3D眼镜”使用了最新的红外线遥控接收头,用它来接收电视发过来的同步信号。
这种主动式快门眼镜技术的优点在于它的残影少,而且不论是电视、电脑屏幕还是投影机,只要更新频率能达到要求,就能导入这个技术,因此现在市面上大部份即将上市的3D显示系统,包括Sony、Panasonic、Samsung等电视上,及NVIDIA的3D眼镜和部份的电影院,都可以看到主动式快门眼镜的踪迹。
亿光电子(亿光电子工业股份有限公司)开发了两款专用的红外线遥控接收头IRM-H6系列与IRM-H9系列用于这类3D眼镜上,广州市超毅电子有限公司是亿光电子的一级代理商,超毅电子有许多做3D眼镜的大客户,这两款红外线遥控接收头均有现货供应。
下面介绍一下这两款红外线遥控接收头的区别。

红外线遥控接收头工作原理
红外线遥控接收头的工作原理:当红外发射管发射出一组红外线后,如果接收器接收到了红外信号,接收头将其放大、整形后,通过天线送至接收器。
红外线遥控接收头主要由控制电路、前置放大电路和红外接收头三部分组成。
1.控制电路
该部分包括四部分:输入端(输入信号)、输出端(输出信号)、整形放大电路和红外发射管。
输入端(输入信号)用来控
制接收头的工作状态,输出端(输出信号)用来驱动红外发射管,整形放大电路使接收头的输出信号与输入信号达到同步,红外发射管产生红外线并传输到接收头,而红外接收管将发射出来的红外线转换成电信号,再经放大、整形后送到解调器,解调后的信号经过解调电路解调出模拟量。
2.前置放大电路
该部分包括四部分:放大电路、滤波电路和共模抑制电路。
前置放大电路的作用是将接收头发出的红外线通过后级放大、整形后变成可供本系统使用的红外线。
另外,在一些设计中还需要根据实际需要适当地调节前置放大电路的增益。
