基于单片机的智能拐杖软件设计

Smart crutch software designAbstractAt present,the global population is about 7.7 billion,and China is theworld's most populous country with a population of 1.4 billion.Similarly,China's population disability rate is also the highest in the world.Accordingto the World Health Organization,there are currently nearly 45 million blindpeople worldwide,and 180 million people with various vision problems,and nearly7 million new blind people worldwide every year,and China's data at 16 years,The number of visually impaired people has increased to 17.31 million.What iseven more frightening is that due to population growth trends and aging,thetotal number of blind and visually impaired people will double in the next tenyears if effective measures are not taken.In view of the above problems,this topic will design a STC89C51 single-chipmicrocomputer as the controller,and use the HC-SR04 ultrasonic ranging moduleas the sensor.Make a blind crutch with simple structure and good early warningpath detection function.Keywords:MCU,sensor,ultrasonic,Smart crutches
