【正文】 ing 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。 crankshaft。 metal magic memory Introduction Infrared Data Communication Technology is the world wide use of a wireless connection technology, by the many hardware and software platforms supported. Is a data through electrical pulses and infrared optical pulse switch between the wireless data transceiver technology. Infrared transceiver products with low cost, small, fast transmission rate, the pointtopoint transmission security, not subject to electromagic interference and other characteristics that can be achieved between the different products, rapid, convenient and safe exchange and transmission, In short distance wireless transmission have a very distinct advantage. Infrared transceiver products in the portable product of a great role. At present, the world39。 mediumspeed model : the highest rate of Mbps and 。 C), moment will be kept around to infrared radiation. Only higher temperature of objects strong infrared radiation, lowtemperature objects infrared radiation weaker. Therefore infrared feature is the greatest mon in nature, it is called thermal radiation called thermal radiation. Infrared cameras, infrared night market pyroelectric infrared detectors and some other missiles aiming at is the use of this characteristic of infrared work. Infrared and visible light pared to another characteristic of a variety of colors. As the longest wavelength of visible light is a wavelength of the shortest times (780 nm380 nm), So is called an octave. And infrared wavelength is the longest shortest wavelength of a times, and the longest wavelength infrared is the shortest wavelength of 10 times, that is, 10 octave. Therefore, if visible light can be expressed as seven colors, infrared may performance 70 colors, showing the rich colors. Infrared smoke through the good performance, which is also one of its features. Because not visible to the infrared, it has little effect on the environment. By the wave infrared rays than the long wavelength radio waves, infrared remote control will
