Problems solved by technology

The popular IrDA is a standard of this kind of technology. The infrared communication port designed according to the IrDA standard generally has a transmission rate of 2400bps~115.2kbps, and some can even reach 4Mbps, but it has a weakness that the transmission distance is relatively short. It can reach 1m, which is far from meeting the needs for long-distance data transmission using infrared

Description

technical field [0001] The invention relates to an infrared transmission device, in particular to a high-speed long-distance directional data infrared transmission device. Background technique [0002] At present, infrared communication technology is mostly used in the exchange of data of small mobile devices and the control of electrical equipment. Data infrared transmission has the advantages of large data transmission volume and high transmission rate. The popular IrDA is a standard of this kind of technology. The infrared communication port designed according to the IrDA standard generally has a transmission rate of 2400bps~115.2kbps, and some can even reach 4Mbps, but it has a weakness that the transmission distance is relatively short. It can reach 1m, which is far from meeting the needs for long-distance data transmission using infrared. Contents of the invention [0003] The object of the present invention is to provide a high-speed long-distance directional data ...
