A traffic vehicle whistle sound source localization system

Abstract

The invention relates to a traffic vehicle whistle sound source positioning system, which includes a main control terminal, which is used for information collection and processing, and has a built-in area map; an area division module, which divides the area map into several adjacent areas, and performs mark, and each marked area is equipped with an information collection terminal; the vehicle whistle sound collection module is used to collect the sound of the vehicle whistle, and has a number of sound collection units corresponding to each marked area, each sound The collection unit is coupled to the corresponding information collection end and collects the sound of the car whistle corresponding to the marked area; the whistle vehicle positioning module is used to locate the whistle vehicle, and has built-in several whistle vehicles corresponding to each marked area The positioning unit, each horn-honking vehicle positioning unit is coupled to the corresponding information collection end and locates the whistle-honking vehicle in the corresponding marked area in real time. The invention has the effect of improving the positioning accuracy of the whistle-honking vehicle.

Description

technical field [0001] The invention relates to the technical field of traffic detection, in particular to a traffic vehicle whistle sound source positioning system. Background technique [0002] In road traffic, drivers often honk to attract the attention of other traffic participants (for example, other motor vehicles, bicycles or pedestrians), and in recent years, some cities have formulated rules and regulations prohibiting urban residents Districts, schools and other densely populated areas whistle, so more and more attention has been paid to locating and stopping the prohibited whistle vehicles in time. [0003] In the prior art, when locating prohibited whistle vehicles, the entire urban area is usually monitored at the same time, and there are many densely populated areas that need to prohibit honking within the entire urban area. If simultaneous monitoring is performed, It is inevitable that some vehicles that violate the horn will be ignored, resulting in a decrea...

[0003] In the prior art, when locating prohibited whistle vehicles, the entire urban area is usually monitored at the same time, and there are many densely populated areas that need to prohibit honking within the entire urban area. If simultaneous monitoring is performed, It is inevitable that some prohibited horn vehicles will be ignored, resulting in a decrease in the positioning accuracy of prohibited horn vehicles
