Intelligent blind guide system

Abstract

The invention relates to the field of auxiliary devices for the disabled, in particular to an intelligent blind guide system. The intelligent blind guide system comprises a tactile stick and a wearable device worn on the upper half body of the human body, the wearable device and the tactile stick are each internally provided with a power module and a wireless communication module, an obstacle detector is arranged in the wearable device, and the tactile stick is composed of a holding handle, a stick body and a detecting part at the tail end of the stick body. A single-chip microcomputer is arranged in the stick body, a caution device is arranged on the holding handle, and the caution device is communicated with the single-chip microcomputer. According to the intelligent blind guide system, obstacles with certain height in the advancing direction can be accurately detected through the wearable device worn on the upper half body of a user, the user is reminded of avoidance, therefore, the potential safety hazard is eliminated, and the safety of the user is guaranteed.

Description

technical field [0001] The invention relates to an auxiliary device for disabled persons, in particular to an intelligent blind guiding system. Background technique [0002] At present, there are nearly 13 million visually impaired people in my country, accounting for about 1% of the total population, which is a huge group worthy of our attention. In the past, under the influence of factors such as social prejudice, narrow employment and social areas, and irregular infrastructure construction such as blind roads, this group rarely went out and appeared in the field of vision of normal people. [0003] In recent years, with the opening of the mind, the prejudice against the disabled has been gradually reduced; at the same time, with the introduction of many policies to encourage the integration of the disabled into society and the gradual improvement of various barrier-free facilities in various places, there have been more and more Visually impaired people began to use vari...

Problems solved by technology

However, for the visually impaired, the biggest problem they face when walking is still a safety issue. Among the above-mentioned functions, only the infrared or sound wave detection function can help users find out the obstacles and road conditions ahead of the road.

However, when in use, the user holds the blind stick and moves forward, and the position of the blind stick is mostly at the same level as the user's lower body, so only obstacles with a lower level can be detected

In reality, obstacles with higher horizontal positions, such as tree branches, vehicles with higher chassis, and additions installed on buildings, are very threatening to the safety of the visually impaired. The upper body and even the head of the visually impaired Injuries also occur from time to time, which undoubtedly greatly affects the enthusiasm of the visually impaired to travel normally
