Intelligent blind guiding device and system

Abstract

The invention relates to an intelligent blind guiding device, which comprises a sensor, a control unit, a warning unit, an input unit, a positioning unit and a storage unit, wherein the input unit isused for setting a trip end point for a blind person; the positioning unit is used for acquiring the position where the blind person is located; a customized path is stored in the storage unit, the control unit matches with the stored customized path according to the terminal point set by the blind person and the starting point positioned by the positioning unit, after the matching succeeds, the control unit sends a warning according to the position of the blind person and the optimization details on the customized path, after the matching fails, the control unit generates a path and stores the path in the storage unit; the administrator can add, modify, or delete detail optimization for the customized path. According to the invention, the device can inform the blind person of the road condition information and the environment information in real time, and the blind person can fully sense the road condition ahead of the blind person; meanwhile, the delay phenomenon caused by real-timemonitoring can be avoided, and the comfort of the travel of the blind person is greatly improved.

Description

technical field [0001] The invention relates to the field of blind guide technology, in particular to an intelligent blind guide device and system. Background technique [0002] There are many blind people in our country, and the number of blind people is also increasing year by year. In order to facilitate the travel of the blind, my country has built the longest and most widely distributed blind road in the world. However, due to reasons such as unreasonable planning and artificial restrictions, the actual utilization rate of the blind road that assists the blind is poor and cannot play its due role. For example, there are often obstacles such as telephone poles, trees, and flower beds on blind roads; illegal parking or commercial use; some blind roads are naturally damaged and have not been repaired in time. Based on the above reasons, blind people cannot rely on blind roads to travel. [0003] In order to facilitate the safe travel of the blind, some blind guide devices...

AI Technical Summary

Problems solved by technology

There are many deficiencies in this method: first, because it is real-time monitoring, for blind people, the status ahead is unknown every time they take a step, which leads to great psychological pressure for blind people when traveling; second, guiding the blind The working process of the device is generally: the sensor monitors obstacles, the control unit performs a series of processing such as identification and judgment on the information collected by the sensor, and finally sends out voice or vibration to remind the blind. There will be a certain delay between them. Make the walking experience of the blind poor; third, the existing sensors basically only identify the obstacles in front of the blind, and do not recognize the environment or the condition of the walking surface of the blind
