For the blind, poor vision of the elderly development and design of an intelligent portable wearable blind auxiliary visual recognition system. It helps to solve the problems faced by travel, such as unfamiliar road conditions and obstacles, which can be broadcast through ultrasonic obstacle avoidance module and voice broadcast module to avoid them. After going out, it is difficult for the family to determine its exact location, and it can be located through a small program on the mobile phone to keep track of its whereabouts at any time. If the travel time is not good enough to master the weather and the temperature and humidity are unknown, the voice assistant can be awakened for inquiry through the keyword "your assistant" you "." night warning, the assistant can be woken up manually or by voice to give an alarm. The OLED screen can display the area, the user's drug allergy history, blood type, and the phone number of the user's relatives at any time, thus saving the doctor's rescue time in case of danger. Relatives and friends can quickly find the place of the incident through cloud positioning data, reducing the time wasted due to large-scale search, and has the advantages of accurate positioning, fast transmission, low energy consumption, etc; image recognition uses a pyAI-K210 module, which can perform convolutional neural network calculation and drug recognition under low power consumption, effectively preventing users from taking drugs by mistake and avoiding danger. An infrared temperature measurement module is added to detect people with abnormal body temperature in a timely manner, and the temperature is displayed in real time through OLED display screen, which has the advantages of non-contact and rapid temperature measurement. This system is a blind intelligent auxiliary identification system that integrates modern GPS, ultrasonic ranging, convolutional neural network algorithm, Internet of Things and other technologies to automatically alarm roadblocks ahead, accurately report time and place, accurately grasp the weather, and auxiliary drug identification. Technical advantages: the functions of the auxiliary equipment for the blind in the domestic market can not meet the existing market demand, and only have simple functions such as support and anti-skid. However, this intelligent auxiliary visual recognition system of our company uses electronic technology, automatically locates through GPS, and sends the coordinates of users to their families through the Internet of Things. When family members need to know the location of the user, they can obtain it by sending information through small programs. It also has the function of ultrasonic obstacle detection. When encountering obstacles ahead, the real voice broadcast system; At night, the intelligent auxiliary system can also automatically turn on the red warning light to remind others to pay attention; image recognition combined with convolutional neural network algorithm to help users take medicine. The above technologies greatly optimize the function of crutches and make it more convenient for the elderly and visually impaired to travel and use, with technical advantages. Product features: 1. Set a variety of functions in one, the hardware structure is simple, the function is complete, the work is reliable and small error. 2. Apply the Internet of Things network technology to practice and integrate and use existing mature technologies. 3. The function is concise and practical, easy to operate. The technology is mature and the cost is low, which is convenient for enterprises to cooperate in production and put on the market.
