红外遥控密码锁的设计与实现 摘要 目前国内普遍使用的锁都是机械式的，这种锁结构简单、使用方便，但利用工具可轻易将其打开，这给用户带来极大的困扰和损失。为此，我们设计制作了红外遥控密码锁来解决这个问题。本设计提出以单片机为处理器，无线遥控与电子密码锁技术相结合的整体解决方案。采用单片机为遥控系统的设计，具有灵活多样的编程和结构清晰的电路。本设计由红外接收头hs0038和单片机STC89C52控制的的接收部分构成。此外，红外遥控密码锁可以进行近距离遥控，可以实现遥控开锁、修改密码等诸多功能，在密码外泄时可随时修改密码，具有简单易用、成本低廉、安全可靠、适用广泛的特点，十分适合小区、宾馆、仓库等场所。 关键词：红外遥控、红外接收、密码锁 ABSTRACT At present, the widespread use of all mechanical locks, this lock structure is simple and easy to use, but easy to use tools to open it, which gives users a lot of confusion and loss. To this end, we designed and fabricated infrared remote control locks to solve the problem. The proposed single chip for the processor design, wireless remote control technology and electronic lock combination of the overall solution. For the remote control system using single chip design, with flexible programming and a clear structure of the circuit. The design of the infrared receiver and the microcontroller STC89C52 control hs0038 receiving parts. In addition, the infrared remote control can close remote locks, remote keyless entry can be achieved, change passwords, and many other functions, the password can be compromised at any time change your password, with easy to use, low cost, safe and reliable for a wide range of features, very Suitable for residential, hotels, warehouses and other places. keywords:Infrared Remote Control，Infrared receiver，lock 目录 1 绪论...............................................................4 1.1设计的背景和意义...............................................4 1.2课题的市场前景.................................................4 1.3红外遥控技术的发展现状.........................................5 1.4本课题的主要研究内容...........................................5 1.4.1软件设计的研究内容........................................5 1.4.2硬件电路设计的研究内容....................................5 2 系统设计...........................................................6 2.1红外遥控系统结构...............................................6 2.2红外信号的编码与解码...................
