Blindman traffic guidance system

Abstract

The invention relates to a traffic guiding system for assisting blind person to pass the intersection, as the prior sound hint system has bad guiding effect. The invention comprises a positioning device, a guide line, an electronic cane and a traffic light controller. Wherein the positioning device is arranged embedded to the ground adjacent to the outlet of the typhlosolis corresponding to the intersection. The guide line is arranged at the road between two positioning devices corresponding to the two sides of the road. The electronic cane and the positioning device establish optical communication with the opposite infrared light transmitting circuit and infrared light detection circuit through respective infrared light detection circuit and the infrared light transmitting circuit. The wireless communication circuit of the traffic light controller is connected with the wireless communication circuit signal of the electronic cane. The invention has simple technology and can obtain the position and direction of advance of blind persons, which is convenient for the traffic light controller to provide relative information and guarantee the safety of blind persons to the maximum.

Description

technical field [0001] The invention relates to the fields of information transmission and photoelectric communication, in particular to a traffic guidance system for assisting blind people to pass through intersections. Background technique [0002] Existing crossings maintain traffic order and ensure personal safety in the form of traffic lights. But for the blind, they cannot see the traffic light signals, and it is difficult to pass the intersection safely without outside help. In order to help the blind pass through the intersection, the current main plan is to install specific sounding devices on the traffic lights on both sides of the zebra crossing at the intersection to prompt the traffic light information with different sounds. When the blind person walks to the intersection and prepares to cross the road, he judges the status of the traffic light by distinguishing the prompt sound from the sounding device, and decides whether it is possible to pass.

Problems solved by technology

[0003] But this technology has the following disadvantages: the first, the sound volume is difficult to set

The prompt sound is too small, it is easy to be covered by the environmental noise or cannot be heard due to the increase of the distance. At present, the number of motor vehicles in the city is increasing sharply, and the intersection is getting wider and wider. When the blind person crosses the intersection and leaves the sounding device for a certain distance Difficult to hear or even completely inaudible prompt sound; too loud prompt sound will have adverse effects on others and the surrounding environment. Since the prompt sound needs to work continuously for 24 hours, it is easy to affect the rest of the surrounding residents, and it is strongly opposed by the residents

Second, the zebra crossing interrupts the blind roads on both sides of the intersection. It is difficult for the blind to pass the blind road on one side of the intersection through the zebra crossing and walk onto the blind road on the other side of the intersection.

Third, since there is no guiding mechanism on the zebra crossing, once blind people deviate from the zebra crossing for some reason, it will bring safety hazards
