Video acquisition unit, and over-speed capturing system and method by using the same

Abstract

The invention provides a video acquisition unit, and an over-speed capturing system and method by using the same. The video acquisition unit is composed of a waterproof housing, a capturing camera, a video recording camera, a microprocessor, a memory unit and a main wireless communication module. The over-speed capturing system comprises a microwave detection unit, an over-speed capturing unit, and a video acquisition unit. The microwave detection unit consists of a junction box, a horn-shaped shield and a microwave detector. The over-speed capturing unit includes a slave wireless communication modules, a controller, a high-definition cameras and a tachymeter. In addition, according to the over-speed capturing method, the capturing camera is used for obtaining a vehicle picture and a speed-changing mark, thereby keeping evidences for a later over-speed phenomenon of a vehicle; the video recording camera is used for shooting the speed-changing mark in real time; and the microprocessor carries out an image analysis to obtain a speed limit value, so that speed-limiting data can be provided for over-speed capturing and over-speed monitoring on the speed-changing condition can be realized.

Description

technical field [0001] The invention relates to a monitoring system and a monitoring method, in particular to a monitoring system and a monitoring method for road overspeed monitoring. Background technique [0002] In recent years, my country's expressway construction has developed very rapidly. Since my country's first expressway was built in 1988, by the end of 2010, the mileage of my country's expressways had reached 73,000 km. According to the "National Expressway Network Planning", my country is going all out to accelerate the construction of the main framework of the national expressway network. By 2020, the national expressway network will be basically completed. By then, the total mileage of China's expressways will reach 100,000 km. The new road network consists of 7 capital radial lines, 9 north-south longitudinal lines and 18 east-west horizontal lines, referred to as the "7918" network for short. [0003] In accordance with the unified deployment of the theme ...

AI Technical Summary

Problems solved by technology

[0006] my country's expressway lines are long, the environment changes greatly, and there are many variable speed limits. Therefore, it is very difficult to enforce the law and obtain evidence for the prohibition of speeding on expressways. Therefore, it is necessary to propose a variable speed limit that can be widely used in expressway and other environments. The speeding capture law enforcement and evidence collection method to solve the speeding violations under the condition of banning the variable speed limit on the expressway provides a basis for law enforcement
