System for assisting blind crossing traffice cross based on monolithic processor

Abstract

The invention discloses a system for helping blind person pass through crossing system based on one-chip computer, it includes host and slave unit. Host includes one-chip computer system and radio digital transmitting module and reading interface of pedestrian traffic light state. The slave unit includes one-chip computer system and electronic compass sensor and radio digital transmitting module, the host and slave unit set up public radio communication mode by their radio digital transmission modules.

Description

technical field [0001] The invention relates to a device for assisting a blind person to cross a traffic intersection, in particular to a system for assisting a blind person to cross a traffic intersection based on a single-chip computer. Used in the field of information processing technology. Background technique [0002] The existing scheme of assisting the blind to cross the traffic intersection mainly includes: informing the blind of the current traffic light situation in the voice prompt mode, and assisting it to cross the traffic intersection. [0003] After literature search, it is found that the Chinese patent number is: 03261479.9, and the utility model patent name: new sounding traffic signal lamp. The patent reads as follows: "Consists of lampshade, signal lamp, lamp post, sound box, battery door, battery, lamp holder, switch, wire, chip. It is characterized in that: the lower position of the lampshade covers the upper position of the signal lamp, and the tail en...

AI Technical Summary

Problems solved by technology

[0004] But there are following deficiencies in this technology: 1) need to send prompting sound all the time, no matter daytime or late night

2) It is difficult to set the volume of the speakers. During the day, due to the noise of the surrounding environment, a larger volume is required; at night, if the volume is too high, it will cause noise pollution and affect the rest of the surrounding residents.

3) A standard traffic intersection has two pedestrian traffic lights in different directions, that is, if you want to cross the road at any street corner, you will hear voice prompts from two different directions at the same time (because the horizontal and vertical traffic lights always is opposite), which will cause auditory disturbance to the blind

4) There is no fixed specification for the sound that the speaker emits to represent the state of the traffic light. Different places use different sounds to represent the state of the traffic light, which will affect the recognition of the blind
