A system and method for automatically obtaining evidence of a motor vehicle violating the horn

Abstract

The invention discloses a motor vehicle illegal whistle auto-forensics system, comprising a transmitting system and a receiving system.The transmitting system comprises a transmitting terminal microprocessor and a transmitting terminal data storage connected with the transmitting terminal microprocessor, an input end of the transmitting terminal microprocessor is connected with a motor vehicle whistle button, and an output end of the transmitting terminal microprocessor is connected with a digital horn; the receiving system comprises a receiving terminal microprocessor, a receiving terminal data storage connected with the receiving terminal microprocessor and a communication circuit module to communicate with an upper computer, an input end of the receiving terminal microprocessor is connected with an audio acquisition module and a video acquisition module, an input end of the audio acquisition module is connected with a microphone array, and an input end of the video acquisition module is connected with a camera.The invention also discloses a motor vehicle illegal whistle auto-forensics method.The system and method are reasonable in design, high in robustness against environment noise attack, high in practicality, good in service effect and convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic management, and in particular relates to a system and method for automatically obtaining evidence by a motor vehicle violating the whistle. Background technique [0002] As the number of motor vehicles continues to grow, motor vehicle honking has become the main source of environmental noise in urban areas. Although the traffic control department has set up a number of no-honking areas, it is difficult to obtain evidence under current technical conditions. Vehicles are collected for evidence and punished, and the no-sounding area is useless. [0003] In order to solve the above problems, the Chinese patent application number 200710057183.0 discloses an electronic evidence collection device for vehicle violation whistle, electronic police system and evidence collection method, and the Chinese patent application number 200710097878.1 discloses a vehicle violation whistle automatic eviden...

AI Technical Summary

Problems solved by technology

The disadvantage is that the wireless signal used is easily affected by the vehicle's running speed, transmission and reception distance, and the national database needs to be connected to the Internet, otherwise, it is only suitable for illegal whistle collection in small areas

At the same time, if the signal of a vehicle is compared with the national database, a large amount of calculation time is required, and the real-time performance is poor. The traffic police handheld device mentioned above cannot display the license plate number of the offending vehicle in real time.

The Chinese patent with the application number 201420300914.5 discloses a car whistle identification device, which replaces the above-mentioned wireless signal with an ultrasonic signal, and encodes the information of the motor vehicle before sending it. The reliability of the system is unstable due to the influence of the transmission distance and the driving voltage required for transmitting ultrasonic waves.

[0005] The Chinese patent with application number 200820095371.2 discloses a whistle monitoring device and whistle monitoring system, which mainly considers reminding the driver not to whistle during the prohibited time and area, and needs to store the on-board data of the prohibited time and area Carry out regular upgrades, the maintenance and upgrade of the on-board database is the main factor limiting its practicality

[0006] To sum up, none of the existing technologies can solve the problem of automatic evidence collection of motor vehicles violating the rules and regulations.
