Embodiment Construction

[0034] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.

[0035] The invention provides a parking billing device based on license plate recognition, which utilizes the 433 frequency band to realize the data transmission of the parking time of vehicles entering and exiting, so as to perform billing.

[0036] Such as Figure 1-2 The shown parking metering device based on license plate recognition includes a camera 1, a housing 2 disposed outside the camera, and a control device 3 disposed inside the housing. The camera is connected to the control device, and the housing is also provided with a The communication antenna 4 connected to the device, the control device uses the license plate recognition technology to obtain the license plate information of the vehicle in the vehicle video frame captured by the camera, wherein,

[0037] The communication antennas include at least one 3G / 4G ...

Abstract

The invention discloses a parking charging apparatus, system and method based on license plate identification. The apparatus comprises a camera, a housing disposed outside the camera, and a control device in the housing. The camera is connected to the control device. A communication antenna connected to the control device is connected with the outside of the housing. The control device obtains information of a license plate of a vehicle in a vehicle video frame captured by the camera by means of a license plate identification technology. The communication antenna comprises at least one 3G / 4G antenna, at least one 433 frequency-range antenna, and at least one WiFi antenna. Since 433M signals are strong, the communication antenna provides along transmission distance, exhibits high penetrating and diffraction capabilities, and is low in attenuation during transmission. The vehicle entry time is shortened by means of a license plate recognizer through the license plate identification technology, and the vehicle parking efficiency is improved. The utilization of the 433 frequency-range antenna enables the reliability of data transmission to be improved. The parking charging apparatus is convenient and fast to install.

Description

technical field [0001] The invention belongs to the technical field of communication, and specifically relates to a parking charging device, system and method based on license plate recognition. Background technique [0002] The current parking lot charging system mainly realizes parking charging by sending the vehicle entry time recorded by the charging device at the entrance to the charging device at the exit through wireless communication transmission. Generally speaking, the current wireless communication transmission mode is mainly through wireless LAN (IEEE802.11b / IEEE802.11g), Bluetooth, ZigBee and other wireless networks. This is because 2.4GHz is an ISM frequency band common to all countries. However, since the transmission loss is proportional to the frequency, that is, the higher the frequency, the greater the transmission loss, or, in the case of the same transmission loss, the transmission distance is inversely proportional to the frequency, that is, the higher...
