Fixed intersection electric police grasp shoot device

Abstract

A fixed intersection electronic police capture device includes a wide-angle camera, a video camera, an embedded industrial control host, a ground sensing coil, and an underground ground sensing vehicle detector; the wide-angle camera and the video camera are connected to the embedded industrial control host through an interface, and the embedded industrial control host There is a control management module; the ground sense coil inputs the inductance signal to the buried ground sense vehicle detector, and the buried ground sense vehicle detector analyzes the change of the coil inductance signal, and notifies the vehicle passing signal to the embedded industrial control host; the traffic light signal also Connect to the embedded industrial control host through a converter; when the red light signal and the vehicle passing signal appear at the same time, the control management module of the embedded industrial control host controls the wide-angle camera and video camera to collect digital photos and video frames, and package and transmit them for processing. The invention can greatly improve the detection rate of violations of speeding and running a red light, and can perform real-time violation detection and real-time snapshot of crossing vehicles without manual participation.

Description

technical field [0001] The invention relates to a traffic control system of road vehicles, in particular to a fixed intersection electronic police capture device for maintaining traffic safety and order. Background technique [0002] With the increase in traffic volume year by year, coupled with sudden meteorological factors and many human factors, limited traffic resources are often stretched, and traffic jams often occur in places with dense traffic flow. The traffic police who maintain traffic safety and order are of course indispensable to the smooth flow of urban traffic, but at the same time, it also makes people think of using electronic equipment to participate in the control and management of road vehicles, and jointly manage urban motor vehicles in real time. [0003] The current fixed intersection electronic police generally use pure video technology to collect images, and collect video pictures and evidence pictures through long-range and close-range CCD cameras....

AI Technical Summary

Problems solved by technology

[0003] The current fixed intersection electronic police generally use pure video technology to collect images, and collect video pictures and evidence pictures through long-range and close-range CCD cameras. The structure is complex and the equipment is redundant.

At the same time, the resolution of video photos is not high (768×576), and the rate of false shots and missing shots is high

On the basis of a panoramic CCD camera, each lane needs a close-range CCD camera, which is not suitable for the monitoring of wider roads, and the multi-channel video codec will also seriously affect the performance of the system; at the same time, most of the existing An electronic police can only govern one crossing, and it is dealt with afterwards

Impossible to punish illegal vehicles in real time, resulting in many non-local vehicles not being effectively punished
