"基于51单片机的汽车红外遥控门锁防盗报警器设计"

The graduation thesis "Design of Infrared Remote Control Door Lock Anti-theft Alarm for Automobile Based on 51 Single Chip Microcomputer" introduces the design and implementation of an anti-theft alarm system for automobiles using infrared technology and single chip microcomputers. The system is cost-effective, easy to install, and provides stable anti-theft performance with strong anti-interference ability and high sensitivity. The system consists of hardware and software design. The hardware includes the single chip microcomputer control circuit, the infrared master-slave circuit, the driving alarm circuit, the LED control circuit, and other components. The processor uses the 51 series single chip microcomputer STC89C52, and the entire system operates under the control of the system software. The software can be divided into several modules including data collection, keyboard control, and alarm sub-functions. The system is designed to be easily concealed and not easily detected by thieves. Furthermore, the processed signals can be easily communicated with a PC, facilitating unified management for multiple users. Overall, this design provides an effective and efficient solution for automobile security by utilizing infrared technology and single chip microcomputers. The low cost, ease of installation, and robust anti-theft performance make it a practical and reliable option for vehicle security. The development and implementation of this system align with the concept that science and technology create and lead people's lives, providing a sense of safety and security for automobile owners.
