Law enforcement and evidence taking system for car horning

Abstract

The invention provides a law enforcement and evidence taking system for car horning. The system is composed of a sonar system and a high-definition camera. The sonar system is responsible for collecting sound data, calculating a spectrum characteristic, and determining whether a horn sound is an effective one based on the spectrum characteristic; and if the horn sound is an effective one, the high-definition camera is triggered to capture a car image, licence plate information is identified, and car horning feature audio frequency information is recorded. Meanwhile, the sonar system calculates sound field data, draws a sound field graph, and provides a horn sound coordinate; and the horn sound coordinate, the licence plate information, and the car horning feature audio frequency information are stored and are used as a law enforcement basis. According to the system provided by the invention, defects in the prior art are overcome; accurate and strict evidence taking of car horning can be realized and evidence can be fixed, so that the reliable basis can be provided for law enforcement and punishment. Moreover, the system has advantages of simple structure, low cost, and high reliability and is suitable for large-area popularization and application.

Description

Technical field [0001] The invention relates to a car whistle law enforcement evidence collection system, which belongs to the technical field of intelligent law enforcement. Background technique [0002] The whistling of vehicles in urban areas can cause serious disturbance to the people, so most areas stipulate that vehicles are prohibited from whistling in urban areas. However, at present, there is no strict method for obtaining evidence for the honking of vehicles, because the sound source cannot be accurately located, which makes it impossible to obtain evidence directly from the vehicle, and even if the vehicle is captured, the evidence cannot be fixed. [0003] Therefore, how to rigorously collect evidence and punish the whistle of vehicles is a difficult problem for those skilled in the art to solve. Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a system that can strictly collect evidence for vehicle whistle and ...
