Red outside the transceiver product have cost low, small scaled turn, the baud rate be quick, point to point SSL, be free from electromagism thousand Raos , can realization information at dissimilarity of the product fast, convenience, safely exchange and transmission, at short distance wireless deliver aspect to own very obvious of with red outside the data deliver a technique more and more mature, the cost descend, red outside the transceiver necessarily will get at the short distance munication realm more extensive of application. The purpose that design this system is transmit customer’s operation information with infrared rays for transmit media, then demodulate original signal with receive circuit. It use coding chip to modulate signal and use decoding chip to demodulate signal. The coding chip is PT2262 and decoding chip is PT2272. Both chips are made in Taiwan. Main work principle is that we provide to input the information for the PT2262 with coding keyboard. The input information was coded by PT2262 and loading to high frequent load wave whose frequent is 38 kHz, then modulate infrared transmit dioxide and radiate space outside when it attian enough power. The receive circuit receive the signal and demodulate original information. The original signal was decoded by PT2272, so as to drive some circuit to acplish customer’s operation demand. Keywords: marine diesel。s 150 million piece of equipment used infrared technology in electronic products and industrial equipment. medical equipment and other fields widely used. For example , 95% of the notebook puters on the installation of infrared transceiver interface the majority of the cell phone is also the allocation of infrared transceiver interface. With the exchange of quantitative data, infrared data munications will enable cell phone data transmission more convenient. With infrared data transmission technology matures, perfect, low costs, Infrared Transceiver in short distance munications will be more widely applied. Materials and Methods infrared remote control transceiver product structure and type Currently infrared transceiver in accordance with the mode
