点对点红外通讯装置的设计

在现场使用手持终端与智能电能表进行红外通信时,为确保使用广播命令时通信正确必须输入指定智能电能表的通信地址,既费时又费力。为解决该问题设计了一种用广播命令实现点对点红外通讯的装置,该装置包括瞄准红色激光和红外发射两部分,已批量生产并应用于现场收到良好的效果。

The design of the point-to-point infrared communication device

When the power sector field operations staff for infrared communication use handheld terminals and intelligent watt-hour meter, if use broadcast command, the adjacent intelligent watt-hour meter will also receive the infrared signal from the handset, Then the handset can"t be normal communication between intelligent watt-hour meter.In order to ensure the communication right must specify the address of the intelligent watt-hour meter, but specify the address is difficult, input errors and reduce the work efficiency in practical application,.To solve this problem, this paper designs a point-to-point infrared communication device.This device consists of a target red laser and infrared emission, The broadcast command is used to implement the point-to-point communication.It has received the good effect in application.
