Intelligent access system for public security

Abstract

The invention discloses an intelligent access system for public security, which comprises a camera shooting and auxiliary lighting unit, a vehicle detection unit, an image collecting and processing unit, a transmission unit and a central management unit, wherein the camera shooting and auxiliary lighting unit outputs a video signal; the vehicle detection unit outputs a vehicle detection signal; the outputted vehicle detection signal and the outputted video signal are inputted to a signal input end of the image collecting and processing unit; a signal output end of the image collecting and processing unit outputs license plate information; the outputted license plate information is inputted to a signal input end of the central management unit; and the central management unit stores the license plate information in a database. The intelligent access system can achieve vehicle detection, vehicle license plate automatic identification, monitored vehicle searching, vehicle speed determination, overspeed alarm, traffic flow statistics, data transmission, remote maintenance, data retrieval, fault tolerance and anti-theft alarm functions.

Description

technical field [0001] The invention belongs to the field of intelligent transportation and electronic police, in particular to a security intelligent checkpoint system. Background technique [0002] At present, there are quite a few cases related to motor vehicles among various criminal crimes, such as traffic hit-and-run, theft of motor vehicles and so on. If an automatic monitoring point is set up on the important roads in and out of the urban area and the key sections of the expressway to realize the 24-hour uninterrupted and all-weather automatic recording of the passing vehicles, that is, the installation of the road vehicle intelligent monitoring and recording system (commonly known as "smart bayonet" ), it can provide important clues and basis for local public security departments to detect cases, and can effectively improve the management level of public security traffic police departments on motor vehicles. In addition, the system also has the functions of speed m...

AI Technical Summary

Problems solved by technology

The current bayonet system often has a single function, lacks diversification, and cannot meet actual needs. The recognition of license plates is often based on a single image recognition method, which cannot avoid accidental errors. The recognition rate of the system is often not high. In addition, the change of the environment often It has a great impact on the system, and the system cannot quickly adapt to the change of the environment
