The design of remote system
摘 要
随着科学技术的飞速发展，信息的飞快传播，红外遥控在人们的生活中已经成为不可或缺的部分。本文重点介绍了利用单片机AT89C51和AT89C2051实现红外发射和接收电路的设计方法。发射电路采用单片机89C2051将待发送的二进制信号编码调制为40KHz的脉冲信号通过红外发射管发射红外信号。红外接收端采用一体化红外接收头HS0038接收红外接收信号。它同时对信号进行放大检波，整形得到TTL电平的编码信号再送给单片机。经单片机解码实现对不同设备的控制。整个电路耗电省、简单可靠、操作灵活、性能价格比高，较好地满足了现代生活，生产和科研的需要。广泛应用在家用电器,安全保卫,及人们的日常生活中。例如电视机的遥控，音响设备的遥控，电风扇的遥控，安全保卫报警器，遥控空调器，自动门等均可采用红外遥控技术来实现。

ABSTRACT
With the rapid development of technology, the rapid dissemination of information means that infrared control has become an indispensable component in people’s life. The article highlighted the design method of transmitting and receiving circuit by infrared control which use single-chip microcomputer AT89C51 and AT89C2051. The emission circuit concocts the binary system signal coding which is prepared to send with the signle-chip microcomputer 89C2051.Then the pulse signal uses infrared emission diode to send the infrared signal. The infrared signal is received by the integrative infrared receiving HS0038. At the same time the signal is magnified and plasticed to get the TTL coding signal sending to the signle-chip microcomputer. After that the signle-chip microcomputer decodes the signal to control different equipments. The entire circuit is simple, reliable, flexible operation，high-performance, of high value and low cost, and it can meet the modern life, production and research need. The infrared remote system is abroad used in the wirings, security ward and people daily life. For emample, it can be used to remote control TV, raido and air-condition. Also used in security alarm, auto door and so on.
