"智能拐杖：基于单片机的硬件设计与应用"

Abstract: With the rapid growth of science, technology, and manufacturing industry in China, the application of intelligent device control technology in daily life and industrial production activities has become widespread. This not only saves human resources but also greatly improves the efficiency of people's lives and production, promoting the rapid development of science and technology while enriching people's lives. The research and development of navigation devices have always been a focus of research in various countries, not only because they have significant social significance but also because they have considerable research significance in multiple research fields such as robot vision. Navigation devices that provide road information can also have the same effect on automated robots. Many studies have had successful cases. This design uses the STC89C51 microcontroller as the main control board and the HC-SR04 ultrasonic distance sensor as the detection device to achieve the effect of blind navigation. This instrument has a simple structure and reliable functions. It can detect obstacles in front and alert the user to be careful when reaching a preset range, thus achieving the effect of intelligent blind navigation. Keywords: STC89C51 microcontroller, HC-SR04 ultrasonic distance sensor, intelligent crutches.
