Description

Technical Field

[0001] The utility model relates to the technical field of blind path guidance, in particular to an intelligent blind path guidance device for blind people to travel. Background Art

[0002] According to the data released by the Blind Association, there are nearly 18 million blind people in China. The biggest difficulty for these blind people in life is the inconvenience of traveling. Although the blind can rely on guide dogs to travel, guide dogs can help them walk safely, and guide dogs are gentle and will not attack people, and guide them to avoid obstacles and avoid danger. However, the training process of guide dogs is very strict, and the elimination rate is extremely high. There are only more than 200 guide dogs in my country, which is less than the number of giant pandas, the national treasure. However, the number of blind people in my country is close to 18 million, and the number of guide dogs is not even a fraction of the number of blind people. Therefore, relying on guide dogs to solve problems is a waste of time. Therefore, it is not possible to solve the travel problem of the blind for the time being. Among them, the "Intelligent Blind Path Voice Control Reminder System" disclosed in the application number "CN207082218U" has solved the problem that traditional pedestrian blind paths are designed with different concave and convex structures to serve as reminders and instructions. However, due to the difficulty in distinguishing the concave and convex structures of the blind paths, some road blind paths have abnormal faults such as damage, which makes it impossible to accurately convey the reminder content, and the actual auxiliary function is limited. Especially in some traffic intersections, bus stops, pedestrian overpasses or ramps, the concave and convex structure distinction function of the blind path itself cannot fully know the specific conditions of the road ahead, which brings difficulties to the travel of the blind. After further searching, it was found that the "Intelligent Blind Path Based on Computer Vision" disclosed in the application number "CN216427898U" effectively solved the technical disadvantages that the blind path is built on the sidewalk and is easily occupied by bicycles and other items. Although the blind path is an important facility to assist the blind in traveling, it has not been able to fully play its role, causing inconvenience to the blind group. However, in actual use, a blind path guiding device with a similar structure for blind travel still has many defects, such as: Although some cities have set up some However, it is not practical for the blind to travel. Most of the blind paths are made of the same material as ordinary roads, but the surface is cut in the form of blind paths. The texture of the blind paths is indistinguishable from that of ordinary roads, and it does not bring any substantial help to the blind. In terms of color and texture, the design of the blind paths is not differentiated according to the different needs of the blind, and it is difficult to bring convenience to the blind. The texture of the granite and marble blind paths that are currently used more often will also cause slipping in bad weather. In terms of color, the medium yellow blind paths will be greatly worn and faded after being exposed to the sun and rain, so it is necessary to design an intelligent blind path guiding device for the blind to travel. Utility Model Content

[0003] The purpose of the utility model is to provide an intelligent blind path guiding device for blind people to travel, so as to solve the problems raised in the above background technology.

[0013] 1. Through the cooperation between the Arduino nano main control board, the ultrasonic sensor and the MP3 player, the ultrasonic sensor can detect whether there is an obstacle ahead and feed back the detection result to the Arduino nano main control board.
