Abstract

The invention relates to a peer-to-peer infrared communication device, which is stable in system and well in running, and enables reading work of an electricity meter to be more convenient and efficient. The peer-to-peer infrared communication device comprises an infrared transmitting circuit, an infrared signal gathering device, an infrared receiving circuit, a carrier modem and a carrier modulator. The peer-to-peer infrared communication device is characterized in that an infrared transmitting part and an infrared receiving part adopt an integral structure; the carrier modulator is connected with the infrared transmitting circuit; the infrared transmitting circuit is divided into three paths which are connected with the infrared signal gathering device; an infrared gather signal generated by the infrared signal gathering device is received by the infrared receiving circuit; the infrared receiving circuit is connected with the carrier modem; one serial port TXD (Transmit Data) end is also connected to the front end of the infrared transmitting circuit; the other serial port TXD end is connected to the output end of the carrier modem.

Description

technical field [0001] The invention belongs to the technical field of smart electric energy meters, and in particular relates to a point-to-point infrared communication device. Background technique [0002] When performing smart meter work or detection, usually dozens of smart electric energy meters (hereinafter referred to as electric meters) are installed on a meter wall, and the installation distance is relatively close. When the traditional handheld terminal (hereinafter referred to as the handheld) conducts infrared communication with the meter, due to the large angle of infrared signal emission, the coverage area is wide. If broadcast commands are used to communicate with the ammeter, then multiple meters will respond to the handheld at the same time, causing the communication with the ammeter to fail. In this way, the communication address of the ammeter must be input to ensure the normal communication. Each multi-function meter has its own address code. In the trad...
