A New Generation of Intelligent Aid Cane for Blindness Based on STM32

With the rapid development of urban traffic, the travel of the visually impaired is facing great challenges, and the traditional blind rod can no longer meet their needs for safe travel. At present, the development of front-end guide products is in a bottleneck period, and the application problems of traditional guide products are frequent, and there is a lack of innovation and ways to solve the problems. Learn from the popular intelligent devices in the last five years, thereby liberating the hands of the visually impaired, providing more accurate navigation services, improving the living standards of the blind, and ensuring the safety of the blind. In addition to visual impairment, blind people have the same intelligence as normal people. Normal travel is part of the independent life of disabled people, and they enjoy the same right to freedom as normal people. Providing travel freedom for the blind is conducive to equal participation in society and improving living standards. In order to solve the problem of difficult travel for the blind, we will design an intelligent guide cane, which is based on STM32 microcontroller and supported by GPS positioning module, ultrasonic ranging module, GSM module, voice module, etc., which can realize multiple functions such as real-time positioning, obstacle alarm, sending SMS, calling emergency contacts and so on. Walking stick adopts voice broadcasting and key operation to carry out man–machine interaction. The intelligent blind rod has complete functions, small size and low cost, and is easy to scale production.
