Pedestrian crossing traffic light reminding method and device based on biological frequency

Abstract

The invention discloses a pedestrian crossing traffic light reminding method and device based on biological frequency. The reminding device comprises a power module, a control module, a clock module, a signal collection module, a frequency generator and a voice module. The input end of the control module is respectively connected with the power module, the clock module and the signal collection module, the output end of the control module is connected with the input end of the frequency generator, and the output end of the frequency generator is connected with the input end of the voice module. According to the pedestrian crossing traffic light reminding method and device based on the biological frequency, signals of different frequency fluctuations generated by the frequency generator are used for representing different kinds of traffic signal information according to the changes of the traffic signals of a pedestrian crossing, the blind and seeing eye dogs can sense the changes of a pedestrian crossing traffic light according to the respective biological frequency sensitive range designed in the pedestrian crossing traffic light reminding method and device based on the biological frequency, the blind and the seeing eye dogs can pass through the pedestrian crossing safely, and traffic accidents can be avoided.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a method and device for reminding pedestrian crossing traffic signal lights under biological frequency conditions. Background technique [0002] At present, most of traffic crosswalks only use traffic lights or simple buzzer to prompt blind people and ordinary pedestrians to pass through the crosswalk. The function is very single and belongs to passive traffic signal prompting. With the rapid development of traffic signal control technology, the voice prompter for the blind crossing the street has been widely used. It can actively prompt the signal status of the intersection with automatic voice and buzzing mode, and change the passive display of the signal into an active prompt to remind blind people and ordinary people. Pedestrians pass the crosswalk according to the traffic signal instructions, which strengthens the prompting effect of the signal; but it is only...

[0002] At present, most traffic crosswalks only use traffic lights or simple buzzers to remind blind and ordinary pedestrians to pass through the crosswalk. The function is very single, and it is a passive traffic signal prompt.

With the rapid development of traffic signal control technology, the voice prompter for the blind crossing the street has been widely used. It can actively prompt the signal status of the intersection with automatic voice and buzzing mode, and change the passive display of the signal into an active prompt to remind blind people and ordinary people. Pedestrians pass the crosswalk according to the traffic signal instructions, which strengthens the prompting effect of the signal; but it is only helpful to the blind to pass the crosswalk, but it is difficult for the severely blind or guide dogs to fully play the guiding and prompting role of the crosswalk traffic signal; and the blind The sound decibel level of the voice prompter for crossing the street is also fixed. During the peak commute period, there are many people in the car and the sound is noisy, the prompt signal will be submerged in the noise, and it is difficult to distinguish the traffic lights through the sound effect.
