摘要
 电子技术的飞速发展，给古老的锁具生产带来了巨大的变革，现代的电子技术与机械技术相结合，产生了一大批如声控锁，磁控锁，密码锁，遥控锁，指纹锁等先进的锁具。
    本课题主要讲述了红外遥控电子密码锁的设计，包括了红外遥控电子密码锁的硬件方面的设计和软件方面的设计，本设计的主要任务是实现红外遥控开锁，
开始在程序中修改密码,实现报警功能。
 本设计主要用到了两块芯片，AT89S52和SC3010，AT89S52是主要芯片，SC3010是红外发射芯片。由于每块红外发射芯片的编码过程不一样，所以在你解码之前，你必须先了解编码过程才能正确的解码。在本设计中，也会提到如何解码，在本设计中，最主要的接是解码问题。
 关键词：密码锁, 红外线, 解码
                     
 
ABSTRACT
   The rapid development of electronic technology have brought tremendous changes in the production of the old locks, and as the modern electronic technology and the mechanical technology are combined ,many advanced locks are produced such as voice locks, magnetic locks, password locks, remote locks,  figerprint locks and so on.     The main topics on the infrared remote-control electronic password-lock design, a packet of infrared remote control electronic password-lock the design of hardware and software in the design, the design of the main tasks is to achieve infrared remote-control lock, beginning in the proceedings to amend your password, and alarm functions.     This design uses two main chips, AT89S52 and SC3010, AT89S52 is the main chip, sc3010 is infrared emission chip. As each of the infrared emission chip encoding process is different, so you decoding, you must first understand the coding process to be the correct decoding. In this design, also mentioned how the decoding, in this design, is to decode the most important issue.
Keywords：password lock，infrared，decoder
