点对点红外通讯装置的设计

摘要

When connecting the handheld terminals and intelligent watt-hour meters through infrared communication , it is both time-consuming and inefficient to input the address of the intelligent watt-hour meter in order to ensure the right communication in broadcast command .A new point-to-point infrared device implemented by broadcast commands is proposed in this paper to solve the problem .This device consists of a target red laser and infrared emission .It has been produced in volume and received a good effect in application .%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。
