Problems solved by technology

[0005] And the above-mentioned existing automatic collection motor vehicle number plate management system of the motor vehicle number plate adopts the image recognition technology of taking pictures or taking pictures to read the method for the motor vehicle number plate information, there is the following shortcoming that is difficult to overcome: the number plate recognition accuracy rate is easy Affected by cloudy weather, light and darkness, the cleanliness and smoothness of the license plate surface, it is even more impossible to recognize the vehicle license plate when the camera equipment is not installed in a good position or artificially blocked, that is, any factor that affects the electronic image acquisition of the motor vehicle license plate will be the restricting factor of recognition accuracy, and most of the current image recognition technologies often cannot accurately recognize the number plate fonts with similar characters
[0006] Therefore, although GA36-2014 "Motor Vehicle Number Plates of the People's Republic of China" has very strict requirements on the font size, size, shape, installation location, performance and location of photographic / camera equipment, etc., the currently valid The national standard GB / T28649-2012 "Automatic Vehicle Number Plate Recognition System" can only require: the correct rate of license plate recognition: ≥90% (daytime) and ≥85% (night); the correct rate of license plate color recognition: ≥ 80% (daytime) and ≥75% (nighttime)
In the actual operation process, due to the variety and complexity of the shooting environment, the correct rate of number plate recognition and number plate color recognition is lower than the above indicators. Manpower and material resources are used to compare and screen the extracted information of the license plate that has been captured and the physical image of the license plate, and there is no way to investigate the license plate that has been missed
[0007] To sum up, the motor vehicle number plate and its management system in the prior art have the technical defect of low accuracy of number plate recognition

Embodiment 1

[0059] Embodiment 1 of the present invention provides a motor vehicle number plate supporting hybrid networking technology, the number plate includes solid living characters and a general number plate base.

[0060] The solid living characters are detachably connected with the base body of the general number plate.

[0061] General license plate substrate, including front panel protection film, flexible solar cell film, printed circuit board and back protection layer arranged in sequence.

[0062] It should be noted that the solid living characters provided by the embodiment of the present invention and the style of the universal number plate substrate are strictly implemented in accordance with the latest national standards. Membrane" and other related standard settings.

[0063] Among them, the appearance size, quantity and color of the solid living characters in the embodiment of the present invention are strictly in accordance with the requirements of the latest relevant ...

Embodiment approach

[0094] The first method: if Figure 7 shown, on the multi-sided PCB middle layer, located at Figure 4a The positions of the four screw holes for hanging the license plate of the motor vehicle shown are respectively marked as a, b, c, and d, and the surface of the four holes has been covered with copper during the "metal hole" treatment. Assume a is grounded (GND), b, c, and d are respectively connected to the positive pole of the power supply through the second to fourth pull-up resistors R2, R3, and R4, and b, c, and d are respectively input to the "four-input NAND Gate" input of U1. When the number plate is normally suspended, b, c, and d are respectively connected to the metal bracket of the motor vehicle and a through fastening screws and grounded, and U1 outputs a high level; if the motor vehicle number plate is disassembled abnormally and separated from the frame, Points b, c, and d become high potentials due to the action of pull-up resistors, making U1 output low le...

Embodiment 2

[0100] The embodiment of the present invention also provides a motor vehicle license plate management system supporting hybrid networking technology, including the motor vehicle license plate, motor vehicle license plate information reading and wireless remote transmission device, supervision platform, etc. as described in the first embodiment , interconnected through public mobile communication base stations and wired Internet.

[0101] As a preferred implementation, the motor vehicle license plate management system supporting hybrid networking technology provided by the embodiment of the present invention can be found in Figure 11 As shown, the motor vehicle license plate is configured with NB-IoT protocol for wide area networking; configured with LTE-V protocol and NB-IoT protocol for reading motor vehicle license plate information and wireless communication on both sides or above the traffic road. Remote transmission device communication; configured with LTE-V protocol fo...

Abstract

The invention provides a motor vehicle number plate for supporting a hybrid networking technology and a management system, mainly supporting such communication protocols as NB-IoT / LTE-V / IoT, and being capable of conducting downward compatibility of SMS (short message service) and GPRS (general packet radio service) protocol. The motor vehicle number plate consists of solid state living characters and a commonly used number plate base; and the commonly used number plate base comprises a front panel protecting film, a flexible solar cell film, a printed circuit board and a back protecting layer. The circuit arranged on the printed circuit board comprises a first GNSS (global navigation satellite system) circuit, an energy storage battery charging and discharging management circuit and an energy storage battery, a microprogrammed control unit and an information storage circuit, and an information receiving and transmitting circuit. The management system comprises the motor vehicle number plate, a motor vehicle number plate information reading and wireless remote transmitting device, and a supervisory platform. The motor vehicle number plate and the management system provided by the invention is higher in number plate identifying accuracy compared with traditional image acquisition identification, and lower in applied cost, and has multiple kinds of superior performance at the same time, such as global positioning, environmental protection and power saving.

Description

technical field [0001] The invention relates to the technical field of motor vehicle information management, in particular to a motor vehicle license plate and management system supporting hybrid networking technology. Background technique [0002] The use and style of existing motor vehicle license plates in my country have national unified standards, mainly based on the national standard GA36-2014 "Motor Vehicle License Plates of the People's Republic of China". At present, under the premise of conforming to the style setting stipulated in the GA36-2014 standard, the structural setting of motor vehicle number plates mostly uses metal sheets as the base material, and the number plate fonts are stamped and formed on the base material and sprayed with corresponding colors on the surface. E.g, figure 1 Shown is one of the motor vehicle license plates conforming to GA36-2014 "Motor Vehicle License Plates of the People's Republic of China" (the outer dimension is 440mm×140mm, w...
