License plate monitoring device and license plate recognition system

Abstract

The invention provides a license plate monitoring device and a license plate recognition system. The license plate recognition system comprises the license plate monitoring device and a license plate detection device. The license plate monitoring device comprises a spring, a pressure metal sheet, a support piece, a control circuit and a switch, wherein the control circuit is fixedly arranged on a license plate; the switch is connected onto the control circuit in series and is in an off state; the support piece is fixedly arranged on the license plate; and the pressure metal sheet is arranged between the support piece and the spring. The license plate monitoring device and the license plate recognition system have the advantages that the stability is high, the design is more reasonable, the recognition capability to the license plate is higher, and data can be acquired more timely.

Description

Technical field [0001] The invention relates to the technical field of vehicle-mounted communication, in particular to a license plate monitoring device and a license plate recognition system. Background technique [0002] Duplicated vehicles, commonly known as clone vehicles, refer to vehicles that are driven on the road through procedures such as forging or illegally obtaining other vehicle license plates and driving permits. The main hazards of unlicensed vehicles include: severely hindering the control of public security by public security agencies, creating social instability, disrupting the order of transportation market operations, disrupting the economic order of the country, and infringing on the legitimate rights and interests of real vehicle owners. [0003] Traditionally, the monitoring and identification of license plate vehicles mainly use the following two methods: [0004] 1. Relying on human eyes and hand touch for monitoring and identification. This method relies ...

Problems solved by technology

[0006] 1) When the sensitivity of the pressure sensor is high, unintentional collision may cause misreading data upload

Because during the actual use or maintenance of the vehicle, the driver or car maintenance personnel may touch the license plate unintentionally. At this time, the pressure sensor on the license plate monitoring device will mistakenly believe that the vehicle license plate has been modified without permission, and transmit the situation to the vehicle management through the network. Center, thereby causing unnecessary trouble to relevant personnel;

[0007] 2) When the sensitivity of the pressure sensor is low, it is impossible to effectively identify the fake license plate stickers and fake license plates posted on the license plate.

For example, when the user of a fake license plate puts some light-weight fake license plate stickers, CDs or other illegal coverings on the front of the license plate, the pressure sensor cannot effectively detect the cover, and the vehicle management center will not be able to know the fake license plate in time. and other illegal situations
