Title Design of Receiving Circuit For Infrared Wireless Transmission System
As the infrared data transmission with good concealment, low power consumption and other advantages. Because it has certain advantages at close range data transmission and anti-jamming performance, so the infrared communication and the infrared remote control technology is developing rapidly in recent years.
This design is precisely based on the technology, and design a receiving circuit for the infrared wireless transmission system. The circuit includes the infrared receiver circuit, the main control processing circuit, the display circuit, the infrared transmission circuit and other main modules compositions. Infrared receiver circuit receives infrared signal from an external circuit, and then transfers the signal to the main control processing circuit,to complete the follow-up display and signal processing, and transmits a response signal to the transmitter in order to achieve the circuit functions.
