Abstract
The invention provides a pedestrian crossing voice prompt system. An optoelectronic coupler is respectively connected with a traffic light signal system and a single-chip microcomputer processor. The traffic light signal system comprises a red light state signal and a green light state signal. The red light state signal and the green light state signal are converted into signals capable of being identified by the single-chip microcomputer processor via the optoelectronic coupler, and then the signals are inputted to the single-chip microcomputer processor. A time and volume module is connected with the single-chip microcomputer processor. Time and volume information generated by the time and volume module is integrated by the single-chip microcomputer processor, and signal combination processing is performed on the red light state signal and the green light state signal so that a voice signal is generated via combination. Then the voice signal is inputted to a voice selection signal processor. Corresponding voice information is selected and subjected to power amplification by a power amplifier board and then played by a loudspeaker. Helpful information prompt can be performed for pedestrians crossing a street so that safety in crossing the street is enhanced for the pedestrians.
Description
Technical field
The present invention relates to a kind of speech prompting system, relate in particular to a kind of pedestrian's street crossing speech prompting system.
Background technology
In China, in all kinds of sudden hurt accidents, with the overall loss maximum that traffic hazard was caused, the potential life-span loss being caused by it occupies first of various death.The accident rate and the number of casualties that in the situation of road of having an accident, disorderly run a red light with straight section pedestrian and non motorized vehicle are the highest.At present, pedestrian running red light, is a kind of traffic violation the most general in all kinds of traffic offences.This illegal activities not only exist dangerous greatly to traffic offence person's personal safety, and hinder maintenance the coast is clear, the very big inducement that causes especially traffic hazard to occur.
Have recently a popular word " Chinese style is gone across the road ", what say is " gather enough pugil people and just can walk, and traffic lights are irrelevant ".Seeing that people does not see the illegal activities of lamp for this, beyond doubt destroy rule in collective, is compatriots' held that the law does not punish everybody at heart ideas behind, and " Herd Behavior " of comforming.Zeng You expert points out, traffic lights design interval time is unreasonable is to cause one of reason that pedestrian crosses roads randomly.People's patience has certain limit, and exceeding this limit, will to become anxiety even out of one's senses, and for different things, this limit also differs greatly.According to the result of study of announcing, pedestrian waits for that the limit German that restrains oneself of red light is 60S, and Englishman is 45S.China pedestrian props up crossing crossing the larger master of the magnitude of traffic flow, and it is 90 seconds (Tongji University's data) that pedestrian's maximum can be stood the stand-by period.Pedestrian is at waiting time, and the time exceed after 70 seconds, pedestrian starts to advance at a slow speed, finds other positions and waits, and waits and exceedes 90 seconds, pedestrian crossing signal lamp's effect goes to zero, pedestrian's street crossing will, in uncontrollable situation, will cause the behavior of making a dash across the red light.
Summary of the invention
In order to improve the security of pedestrian's street crossing, the invention provides a kind of pedestrian's street crossing speech prompting system.
The object of the invention is to realize by following scheme: pedestrian's street crossing speech prompting system, comprise time and volume module, traffic light signal system, photoelectrical coupler, processor of single chip computer, voice signal, voice selecting signal processor, power board, loudspeaker, wherein, photoelectrical coupler joins with traffic light signal system and processor of single chip computer respectively, traffic light signal system comprises red light phase signal and green light phase signal, red light phase signal and green light phase signal convert the discernible signal of processor of single chip computer to by photoelectrical coupler, be input to again processor of single chip computer, time and volume module and processor of single chip computer join, time and information volume that processor of single chip computer integrating time and volume module are sent, red light phase signal and green light phase signal are carried out to signal combination processing, combination producing voice signal, then voice signal is input to voice selecting signal processor, select corresponding voice messaging, after power board amplifying power, play to loudspeaker.
Further, described pedestrian's street crossing speech prompting system technical indicator is at work:
Operating voltage: AC200～240 V;
Working temperature :-40～80 DEG C;
Working relative humidity: <90%;
The bright response time of lamp: 60 ms;
Voice total length: 4X300S;
Peak power output: 10W.
Further, described processor of single chip computer comprises initialization module, Interruption module, digital sampling and processing, System self-test module.
Further, described voice signal comprises: green light voice message right of way signal, and the blue flash voice message signal that is closed to traffic, when red voice message waiting signal, pedestrian waits for red interval voice message traffic safety propaganda signal.
The invention has the beneficial effects as follows: can be to the information indicating of street pedestrian's help property, be about to change into before red light at green light, when blue flash, remind pedestrian to be closed to traffic, to improve the security of pedestrian's street crossing.And can play public welfare advertisement, traffic information, control traffic message, traffic catch-phrase etc. in red signal intervals such as pedestrians, can effectively extend pedestrian's maximum can stand the stand-by period, has further promoted the effect of this system aspect publicity civilized conducts in vehicle driving, raising quality of the residents simultaneously.
