License plate recognition camera and method for realizing offline fee collection

Abstract

The invention discloses a license plate recognition camera and method for realizing offline fee collection. One or more groups of such license plate recognition cameras are respectively arranged at the entrance and exit of a parking lot. The license plate recognition camera is characterized in that an imaging assembly and a central processing unit are arranged in the license plate recognition camera; the central processing unit integrates a license plate recognition module, a network module, an SQLite3 embedded database, a billing program module, a picture storage module, an RS485 communication and relay signal output module and a server upload module; the license plate recognition camera arranged at the entrance of the parking lot is connected with the license plate recognition camera arranged at the exit of the parking lot through a switch; the switch is connected with a backend server and a PC end; the license plate recognition cameras at the entrance and exit form an internal network through entrance-exit IP mapping; the embedded database is used to store vehicle outgoing and entering data information; and temporary vehicles can still smoothly enter and exit from the parking lot, and the parking fees of the vehicles can be also collected when the parking lot server is offline or is disconnected from the network.

Description

Technical field [0001] The present invention relates to the technical field of license plate recognition charging systems, in particular to a license plate recognition camera device that is applied to a parking lot license plate recognition charging system and realizes offline charging through an internal networking mode. Background technique [0002] With the development of society and economy, the number of cars has increased sharply, and the requirements for traffic control, safety management, and parking fee management are also increasing. The use of electronic information technology to achieve safe and efficient intelligent transportation has become the main development direction of traffic management.

This technology has been widely used in highway toll col...

AI Technical Summary

Problems solved by technology

However, the license plate recognition system currently on the market has the following problems, the computer is down, the server is paralyzed, or the software is out of online monitoring to deal with other things, such as license plate registration, license plate extension, and system maintenance

At this time, the vehicles that have applied for the monthly rental card can enter and exit normally, but the temporary vehicles cannot enter and exit normally and charge fees, resulting in congestion of vehicles at the bayonet, chaotic scenes, and serious economic losses and inconveniences to the property.
