So, the birth of the wireless data transmission mode has changed its traditional technology means .. Because of its low cost, good expansion function, free working conditions and the easy access of advantage, in the field of virtual product market, security alarm system, sensor wireless work system in many aspects has very broad prospects. In order to make the data transmitted in the process of transmission, it can be used for safe and reliable transmission, easy operation, and convenient operation. So it can be used for infrared information technology.. This design mainly by single chip puter 89lpc935 as the design basis, to develop a convenient and easy operation of the information written code measures, in order to the pleted the effective method of a simple infrared data munication system. The design and principle of the related modules of the circuits are pared and pared.. The maximum degree of error rate is reduced, so that the information can be improved in the transmission process.. The design of this system mainly based on the control of single chip write, scan and input the ranks of the keyboard value, the related digital tube dynamic display, infrared data munication clear show. This paper mainly from the position and the working principle of the infrared data munication and its coding and decoding of work on, the theme is divided into two modules to discuss, both for the reception and sending of two parts, and finally according to the related information and standard to plete the final design of the hardware part of the.
