Pedestrian crosswalk traffic signal light reminder method and device based on biological frequency

Abstract

The invention discloses a pedestrian crosswalk traffic signal reminder device and a reminder method based on biological frequency. The reminder device includes a power supply module, a control module, a clock module, a signal acquisition module, a frequency generator and a voice module. The input of the control module The terminals are respectively connected with the power supply module, the clock module and the signal acquisition module, the output terminal of the control module is connected with the input terminal of the frequency generator, and the output terminal of the frequency generator is connected with the input terminal of the voice module. According to the change of pedestrian crossing traffic signal, the present invention uses the frequency generator to generate signals with different frequency fluctuations to represent different traffic signal information, so that blind people and guide dogs can perceive the changes of pedestrian crossing signal lights according to their respective biological frequency sensitivity ranges designed by the present invention, which is convenient for them Safely cross the pedestrian crossing to avoid traffic accidents.

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.
