Intelligent pedestrian street crossing voice prompt device

Abstract

The invention relates to an intelligent pedestrian street crossing voice prompt device, characterized by comprising an alternating current electronic relay control module (1), a power source module (2), a voice integrated module (3), a two-path time control module (4), an electronic voice volume module (5), a power amplification module (6), a wireless receiving module (7) and a wireless transmission module (8), wherein (1) receives pedestrian traffic light signals and provides a stable voltage for (2), and simultaneously provides voice source control signals for (3) and controls (3) to supply a voice source for (5); (2) provides power sources for (4), (5), (6) and (7); one path of (4) controls (2), namely the on and off and time, and the other path of (4) controls (5), namely the conversion of high voice and low voice and time; the voice volumes of a low voice section and a high voice section are respectively manually set through a common potentiometer in (5) and remotely set through an electronic potentiometer; (8) can transmit wireless signals at the high voice section; (7) can receive wireless signals and decode the wireless signals, and controls (6) by (5) to realize voice volume control when pedestrian traffic lights work; and the system voice volume can be changed by 0-20dB along with external environmental noises via the automatic voice volume circuit in (5).

Description

technical field [0001] The invention relates to traffic control for pedestrian crossing, and mainly refers to an intelligent voice prompt device for pedestrian crossing, which is used in conjunction with pedestrian traffic lights and organically combines manual, wireless remote control and automatic volume control. Background technique [0002] Pedestrian crossing the street voice prompting device or prompter that use in the market, 1. be to only control the red light signal, when the pedestrian crosses the red light, prompts the pedestrian to rush the red light danger, then ignores when the pedestrian crosses the green light. For the visually impaired or the blind, if there is no reminder when the pedestrian crosses the green light, they will be at a loss and do not know whether to cross the road; ②Although the pedestrian traffic lights are all controlled, the sound played by the prompt device is solidified. Just invariable, this situation especially when prompting device i...
