技术问答

现在绝大部分家庭使用的电表都是智能表，纯机械式的电表越来越少。现在智能电表有的含有红外表头支持进行抄读，甚至有些智能表还带通信模块可以将数据进行远传。本篇文章笔者将介绍下使用红外收发管进行红外电力电表抄表。

电表的通信协议较新的标准是DL/T 645-2007，属于电力行业标准。该协议规定了通过红外进行抄读时的一些标准和规则。关于红外的一些规定如下：红外线波长为900nm~1000nm，信号调制载波频率为38kHz±1kHz。信号调制波形示意如下图1，光辐射半角≥15°。

图1 信号调制示例波形

笔者接触的项目就是基于规约标准设计一款红外抄表终端对电表数据进行抄读。终端硬件功能框图如下图2，基本流程就是通过红外将采集的电表数据通过NB-IOT模组上传至后台，完成数据的远程采集。

图2 功能框图

项目中使用了KODENSHI（可天士）的红外发射管 SEL955-02和红外接收模组R903HB-7S进行了设计。

关于SEL955-02基本参数如下：

1. 940nm发射波长

2. 高功率低正向电压的GaAs红外发光二极管

3.辐射半角±16.5°

关于R903HB-7S基本参数如下：

1. 额定电压范围2.7~5.5V，额定消耗电流典型值仅为0.38mA

2. 峰值波长940nm

3.中心频率37.9kHz

从以上参数可知KODENSHI(可天士)红外发射管SEL955-02和红外接收模块R903HB-7S完全符合DL/T 645-2007的红外基本要求，于是进行了原理图设计，原理图如下所示。发射电路采用单IO口生产载波和控制信号。接收电路参考手册参考设计进行设计。

图3 原理图

进行了打板验证，局部实物图如下图所示：

图4 局部实物图

测试波形以及功能验证如下图所示，波形可以看出密集的为载波部分，下面是载波放大图片，经测量频率为37.91kHz，数据正常。

图5 测试波形

对电表进行了实际抄读，发现功能正常。测试图片如下：

图6 实际电表测试

综上所述，KODENSHI(可天士)红外发射管SEL955-02和红外接收模块R903HB-7S可成功应用于红外抄表终端。

【应用】可天士红外发射/接收对管SEL533＆SST533用于智能PIR，耗散功率仅为75mW

某客户在设计一款智能PIR产品，打算采用一款分体式的红外对管。根据需求，本文推荐KODENDHI的红外发射/接收对管SEL533＆SST533，发射管发光波长为940nm，接收管光谱响应范围700nm~1050nm，耗散功率仅为75mW。

【应用】推荐可天士红外发射＆接收对管SEL533、SST533用于红外式烟雾报警器，小尺寸，高功率

大家都知道火灾威胁着人民的财产和生命，大多数建筑物都安装有烟雾报警器。常用的烟雾报警器的原理，是红外发射管的红外光束被烟尘粒子散射，散射光的强弱与烟的浓度成正比, 所以光敏管接收到的红外光束的强弱会发生变化,转化为点信号,最后转化成报警信号。
