Automatic blind person navigation system

Abstract

The invention provides an automatic blind person navigation system which comprises a blind person cane. A reed switch is arranged at the bottom end of the blind person cane and connected with a single-chip microcomputer, the single-chip microcomputer is further connected with a sound player and a signal input and output module, and the single-chip microcomputer, the sound player and the signal input and output module are all arranged on the blind person cane. The automatic blind person navigation system further comprises a sidewalk, and a blind person exclusive way provided with a magnetic strip in an embedded mode is arranged on the sidewalk and matched with the reed switch. The automatic blind person navigation system is further in cooperation with a traffic light control system, and the traffic light control system is connected with the signal input and output module in a wireless mode. The automatic blind person navigation system can help blind persons to pass through the sidewalk through voice prompts, the blind persons can go out conveniently, and unnecessary traffic accidents are avoided.

Description

【Technical field】 [0001] The invention relates to an automatic blind navigation system. 【Background technique】 [0002] In this era of rapid development of various industries, people no longer need to take a car when traveling, as long as they drive their own cars, they can go wherever they want, which is fast and convenient. As a result, the traffic flow in cities and towns has become larger and larger, and it has become difficult for people to cross the zebra crossing! Especially at crossroads, every car can also turn right freely when encountering a red light, and it is even more difficult for people to cross the road! Let alone a blind person! [0003] Now, blind people in various regions are not uncommon at all. Every blind person walks on the blind sidewalk on the sidewalk, and when they are about to cross the sidewalk at the intersection, they are a little scared. Didn't they know it was on a crosswalk? How wide is the road? Red light or green light? If it is a ...

Problems solved by technology

[0004] In the past, although many people have developed and used navigation systems that can help blind people travel, the system they developed can only help blind people pass traffic lights, and they can only rely on the sound of "beep, beep, beep". Long and short, to remind blind people whether they can cross the road

When this system is at an intersection, when pedestrians can pass the zebra crossing, it cannot prompt whether there is a car about to turn right. In this way, it is easy to cause blind people not to know that there is a car about to turn right, which may cause traffic accidents.

There are also voice prompts, but this kind of navigation system is the same. When pedestrians can pass the zebra crossing, they cannot prompt whether there is a car about to turn right.
