Problems solved by technology

Traffic conditions are an important part of the normal operation of a city. At present, there are illegal honking in prohibited areas or malicious honking in normal driving conditions in various cities. However, it is a big problem to obtain evidence for illegal honking, because the sound is An invisible thing, the existing electronic police technology is almost impossible to obtain evidence and sound the horn, which brings difficulties to the law enforcement of the traffic police

Embodiment Construction

[0019] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0020] see Figure 1-2 , an illegal whistle capture system, comprising a camera capture system and an omnidirectional passive sonar 1, the camera capture system comprising a host and a high-definition camera 2, the high-definition camera 2 and the omnidirectional passive sonar 1 are connected to the host, the high-definition camera 2 and The distance between the omnidirectional passive sonar 1 is not zero. The omnidirectional passive sonar 1 includes sixteen transducers. The openings of the sixteen transducers all face directly downward. Every four transducers form a row. The host Linux or Windows system is installed inside. The resolution of the omnidirectional passive sonar 1 is not greater than 0.5 degrees, and the sampling frequency of the transducer is 0-5KHz. The high-definition camera 2 uses a bolt camera or a dome camera, the omnidirectio...

Abstract

The invention discloses an illegal honking snapshot system comprising a camera snapshot system and an omnidirectional passive sonar. The camera snapshot system comprises a host and a high-definition camera. The high-definition camera and the omnidirectional passive sonar are connected with the host. The distance between the high-definition camera and the omnidirectional passive sonar is not zero. The omnidirectional passive sonar comprises sixteen energy converters of which the openings are all exactly downward. Every four energy converters form a row. The host is internally provided with a Linux or Windows system. The invention also discloses the work flow of the illegal honking snapshot system. The device is easy and convenient to operate, long in detection distance, fast in snapshot speed, wide in snapshot range and high in positioning accuracy and can solve the problem that the honking evidence cannot be acquired. The device greatly enhances the sound source acquisition accuracy and the video recognition rate. The device can be independently used and multiple devices can be used in a cooperative way so as to be suitable for different situations, and traffic police enforcement can be assisted.

Description

technical field [0001] The invention relates to the field of traffic applications, in particular to a system for snapping illegal whistles. Background technique [0002] Cities, also called urban settlements, are larger settlements formed by the agglomeration of non-agricultural industries and non-agricultural populations. A densely populated area is called a city, which generally includes residential areas, industrial areas, and commercial areas and has administrative jurisdiction. The administrative jurisdiction function of a city may involve a wider area than itself, including residential areas, streets, hospitals, schools, public green spaces, office buildings, commercial stores, squares, parks and other public facilities. Traffic conditions are an important part of the normal operation of a city. At present, there are illegal honking in prohibited areas or malicious honking in normal driving conditions in various cities. However, it is a big problem to obtain evidence ...
