ABSTRACT

 With the advent of the 21st century, an increasingly technological society, all kinds of electronic information technologies to speed the development stage, including information systems technology in microelectronics, computers and modern communication technology, sensor technology, which also includes infrared technology, infrared is a man The naked eye can not see the light, the recent 23 years, budding infrared technology, in various fields has been widely applied. Applied to the production began, and formed a new technology - infrared technology.The design for the lack of traditional mechanical lock designed to control by infrared lock, the main advantage of infrared remote control MCU AT89S51 locks to achieve the design and implementation in the PROTEUS simulation software. The electronic password lock is based on infrared remote control. It is the design of combining technical application of the micro-control unit with infrared remote control technology. A lot of functions are accomplished and it has good market perspective and the value of technical application. This electronic password lock not only meets safety requirements, but also be able to adapt to the needs in some special environment. The circuit of password lock consists of infra-red coding circuit, infrared decoder circuit, the protecting circuit of drop electricity, sound and light alarm circuit, the keyboards and display circuit. This system has the basic function of opening the lock, alarming the error prompt and modifying the password of the users as well as the function of remote control, protecting drop electricity and saving, the hint of sound and light etc.

Keywords: microcontroller; infrared technology; remote control; password lock; PROTEUS simulation
