Nowadays, in the area that tell a state main crossing added the part newly to be used technically at exposure to break the law cry the LED of flute car displays screen, should have only break the law cry fluted, the car brand of relevant car is met appear on screen for a short while. Original, this is to connect city traffic detachment to cry from chaos of severe processing the city zone flute, the correct that installs inside the area first is violated " god implement " -- break the law cry flute is caught take a system.
Henceforth, prohibiting crying chaos of flute a section of a highway presses a horn, will by " sonar policeman " catch pat, be fined 100 yuan punishment.
The reporter is in Lu river hospital respectively the ave saw crossing, canal on the west this explores device by sound wave, photograph what show like head, electron box of screen, data processing is comprised to break the law cry flute is caught take a system. Maize electron shows screen is installed in erect on the pillar of electronic eye, screen upper part is being written " break the law cry flute is monitored " , showing next break the law cry the plate number of flute. Should prohibiting crying only flute a section of a highway pressed a horn, from the system fixed position is caught pat through showing sign of screen exposure plate, need two seconds only.
Why is this to plant after all new and high science and technology? Introduce according to connecting division of city traffic detachment to believe division policeman, break the law cry flute stresses the working principle that takes a system is to pass sonar to collect a system to sound identifying first, repass electron is caught pat a system to catch pat, last real time appears to hint in electronic screen system. This one equipment is monitored through using acoustical source fixed position, video wait for a technology, can cry to the motor vehicle inside 200-300 rice limits flute illegal behavior undertakes real time is collected.
According to introducing, motor vehicle chaos cries flute is relatively general drive abusive, cause bigger noise pollution not only, affect the normal life of road periphery citizen badly also. Be based on obtain evidence problem, violate compasses cry flute is traffic processing difficult problem all the time, policeman of a gleam of executes the law daily in, because lack strong evidence, once encounter,also can teach with criticism only when this kind of problem give priority to.
Break the law cry the sound of flute can does essence of life follow fixed position? "Sound wave explores the array that there is ten microphones unit to comprise on device, every unit can collect audio frequency and energy alone. Although there is many car inside monitoring area per fire detector,cry at the same time flute, the system also can be explored cry the little difference of flute time, part fixed position identifying. Break the law cry after flute car is located, photograph catch instantly like the head pat and identify through analysis of data processing box. " policeman of family letter division introduces, execute the law to ensure condemnatory accuracy, this system can use bray of of all kinds motor vehicle and phone sound of travel of car bray, car, brake sound, engine to bang the sound such as song undertakes distinguishing, avoid environmental noise and motor vehicle to cry flute is promiscuous, from inside noisy environment sound of accurate extraction horn, the phenomenon of theoretic nonexistent miscarriage of justice.
Should prohibiting crying only does flute area have cry does flute behavior calculate break the law?
