Abstract

The invention discloses an intelligent voice blind guider, and belongs to the field of electronic blind guide devices. The intelligent voice blind guider is characterized by comprising a central detecting module, a side wing detecting module, a signal processing module, a vibration prompting circuit and a voice prompting circuit. The central detecting module is connected with the signal processingmodule. The side wing detecting module is connected with the signal processing module. The vibration prompting circuit is connected with the signal processing module. The voice prompting circuit is connected with the signal processing module. Signal collection is conducted through a plurality of intelligent sensors, signals are submitted to the signal processing module to be comprehensively analyzed, prompts are rapidly given, and the response time of blind guiding is effectively shortened. The intelligent voice blind guide dog is simple in structure, easy to operate, low in cost, stable in blind guide performance, good in effect and suitable for use and popularization.

Description

technical field [0001] The invention belongs to the field of electronic blind guide equipment, in particular to an intelligent voice guide for the blind. Background technique [0002] With the continuous advancement of science and technology, more and more smart electronic devices have entered people's lives, bringing great convenience to people's lives. In my country, there are the largest group of blind people in the world, and there are about 9 million visually disabled people. Those who account for about 15% of the total number of blind people in the world will add 450,000 new blind people every year, that is, one person will increase every minute. Blind people who are completely blind have great difficulty in guiding their actions. Traditional walking sticks cannot inform the blind person of the specific position of the obstacle in front of them in a timely manner, which is likely to cause physical injury to the disabled or cause serious traffic accidents.
