Problems solved by technology

However, infrared remote control technology also has obvious shortcomings, such as the longest transmission distance of only a dozen meters; there must be no obstacles between the transmitter and the receiver, and the signal path is directional, and can only accept direct light or reflection; when the battery power is low, the signal decays Seriously, the remote control distance is shortened sharply

Abstract

The invention relates to an ultra-long distance infrared signal extension and wireless retransmission device, which belongs to the technical field of wireless communication. The device comprises two independent parts, including a wireless extension emitter and a wireless extension receiver, wherein the wireless extension emitter comprises a circuit board formed by three parts, including an infrared receiving head, a STM8L single chip microcomputer T and a LoRa emitting end; and the wireless extension receiver comprises a circuit board formed by a LoRa receiving end, a STM8L single chip microcomputer R, an infrared emitting head and a 3.5MM audio adaption wire. By use of the device, the wireless extension emitter and the wireless extension receiver greatly prolong a signal transmission distance through a conversion signal transmission way, and the strong dependency of infrared remote control for a remote control direction is eliminated. Compared with a situation that only infrared signal remote control is used, the device disclosed by the invention has obvious advantages on the aspects of transmission distance and stability.

Description

technical field [0001] The invention relates to an ultra-long-distance infrared signal extension and wireless forwarding device, which belongs to the technical field of wireless communication. Background technique [0002] Infrared remote control technology is a wireless control technology, which is widely used in the control of household appliances and industrial equipment due to its low cost of ownership, low power consumption, excellent anti-interference performance, and reliable transmission. There are dozens of common infrared remote control communication protocols such as Philips PC-5 and NEC, and the NEC protocol is the most widely used. However, infrared remote control technology also has obvious shortcomings, such as the longest transmission distance of only a dozen meters; there must be no obstacles between the transmitter and the receiver, and the signal path is directional, and can only accept direct light or reflection; when the battery is low, the signal attenu...
