[0002] The application of intelligent vehicle access management and identification technology in living communities, banks, supermarkets, scenic spots, etc. is becoming more and more common. At present, intelligent vehicle access management mainly uses a camera device to capture images of vehicles entering the parking lot, recognize license plates, transmit the license plate information to a dedicated controller, then upload it to a network server, guide the vehicle to enter, and save records; at the exit of the parking lot, a license plate recognition camera captures images of the vehicles leaving and recognizes the license plates. The system automatically releases the vehicles with stored information. When online, it is judged by the network server, and when offline, it is judged by the parking lot controller, and the vehicle information is broadcast and displayed. For temporary vehicles, management is carried out according to the parking time to realize the monitoring and management of vehicle entry and exit. The lane information is obtained through license plate recognition, the vehicle management system performs license plate entry and import, authorizes vehicle access rights, and identifies vehicle information through the license plate recognition system to achieve information synchronization and information linkage. It is applicable to dedicated parking lots and communities. However, the problem is that it cannot prevent forgery, that is, it cannot detect license plate cloning.

[0032] As Figure 1 shown, the embodiment of the present utility model provides an intelligent vehicle access management device, which includes: a camera device 3, a vehicle sensing device 6, an RFID reading device, an access control system 5 and a management module 7. The camera device 3 is used to obtain license plate information. The management module 7 is communicatively connected or wired to the camera device 3 and stores vehicle information, which includes license plate information, and is used to receive and compare the license plate information obtained by the camera device 3 and then output an operation instruction. The vehicle sensing device 6 is communicatively connected or wired to the management module 7 and is used to wake up the camera device 3 after sensing a vehicle. The RFID reading device is communicatively connected or wired to the management module 7 and is used to read the vehicle information stored in the RFID tag set in the vehicle according to the operation instruction output by the management module and transmit the reading result back to the management module. The access control system 5 is communicatively connected or wired to the management module and is used to control the opening and closing of the vehicle entrance and exit.

[0033] From the above content, it is not difficult to conclude that when the intelligent vehicle access management device is in the standby state, both the RFID reading device and the camera device 3 are in the standby state and do not work. When the vehicle travels to the vehicle access, the vehicle sensing device 6 senses the vehicle and sends a signal to the management module 7. After receiving the signal, the management module 7 wakes up the camera device 3. First, the camera device 3 can capture the license plate information. After the camera device 3 obtains the license plate information, it sends the license plate information to the management module 7. The management module 7 pre-stores the license plate information of the vehicles allowed to pass. If the management module 7 detects that the license plate information obtained by the camera device 3 can match the license plate information stored in the management module 7, the management module 7 sends an instruction to wake up the RFID reading device to work. If the management module 7 detects that the license plate information obtained by the camera device 3 does not match the license plate information stored in the management module 7, it indicates that the vehicle is an external vehicle. At this time, there is no need to verify the authenticity of the vehicle information, that is, there is no need to wake up the RFID reading device to conduct a secondary verification of the vehicle identity. This avoids the RFID reading device being always in the working state, reduces the reading frequency of the RFID reading device, and can protect the device to extend its service life. The RFID tag is set inside the vehicle. The RFID tag stores the information corresponding to the vehicle, and the RFID tag continuously sends signals, and the signals contain the information of this vehicle. Since the RFID tag sends signals, the RFID reading device woken up by the management module 7 at this time can read the signals sent by the RFID tag. The vehicle information recorded in the RFID tag is obtained through the RFID reading device and sent to the management module 7. The management module 7 can compare and judge whether the vehicle is the vehicle recorded in the management module 7 through the vehicle information in the RFID tag. When the vehicle information in the RFID tag can match the vehicle information recorded in the management module 7, it indicates that the vehicle is a registered vehicle and meets the entry requirements. Among them, in order to prevent license plate cloning, the judgment of the management module 7 is based on the vehicle information in the RFID tag obtained by the RFID reading device. When the management module 7 determines that the vehicle is a registered vehicle in the system according to the reading result of the RFID reading device, the management module 7 controls the access control system 5 to open so that the vehicle can pass smoothly. Of course, a fill light 4 can also be installed at the camera device 3. The fill light 4 can be set facing the position where the vehicle may stop, so that the fill light 4 illuminates the license plate to facilitate the camera device 3 to obtain the license plate information and avoid the situation that the camera device 3 cannot accurately focus due to insufficient light. The dual recognition by the camera device 3 and the RFID reading and writing device avoids illegal vehicles using license plate cloning to impersonate registered vehicles and deceive the system.

[0034] Secondly, as Figure 1As shown, in some embodiments, the RFID reading device includes: an antenna feeder 1 and an RFID reader / writer 2. The antenna feeder 1 is used to receive the signals of the RFID tags. The RFID reader / writer 2 is electrically connected to the antenna feeder 1 and is used to read the signals of the RFID tags received by the antenna feeder 1. The RFID reader / writer 2 is communicatively or wiredly connected to the management module 7 and transmits the received signals of the RFID tags to the management module 7.

[0035] From the above content, it is not difficult to conclude that the antenna feeder 1 is used to receive the vehicle information signals provided by the RFID tags and send the received signals to the RFID reader / writer 2. The RFID reader / writer 2 can establish a network connection with the antenna feeder 1 and read the vehicle information in the RFID tags to achieve efficient collection of vehicle information. At the same time, the RFID reader / writer 2 can achieve contactless information reading and writing, facilitating the acquisition of vehicle information. It avoids some contact-based information transmission during use, reduces the operation difficulty of vehicle operators, and improves work efficiency. And the RFID reader / writer 2 can be connected to a computer network to achieve data storage and management, avoiding the layout of wires and reducing the installation difficulty.

[0036] In addition, as Figure 1 shown, in some embodiments, the intelligent vehicle access management device further includes an RFID tag for storing and sending vehicle information. The RFID tag includes: an RFID chip and an RFID antenna. The RFID chip is used to store vehicle information. The RFID antenna is connected to the RFID chip and sends the vehicle information in the RFID chip to the RFID reading device.

[0037] From the above content, it is not difficult to conclude that the RFID chip can store vehicle information, such as vehicle license plate information, vehicle owner identity information, vehicle owner contact information, etc. The RFID antenna can transmit and spread the vehicle information stored in the RFID chip, thereby transmitting the vehicle information to the RFID reading device so that the management module 7 can obtain the vehicle information and realize the comparison of vehicle information. The RFID antenna can be one or several of aluminum antenna, copper antenna, silver antenna, carbon black antenna, carbon nanotube antenna, graphene antenna, and the processing technology of the RFID antenna can be aluminum etching, laser etching, screen printing, gravure printing, flexographic printing, spraying, die cutting. Further, both the RFID chip and the RFID antenna need to be fixed on a substrate. The substrate not only provides a physical structure to support and protect the internal electronic components, but also can add additional information, such as product number, production date, etc., by printing or other means. The substrate can be made of materials such as PET, PEN, PI, fiber, coated paper, ceramic, etc.

[0038] Further, in some embodiments, the RFID tag further includes a housing, and the RFID chip and the RFID antenna are disposed inside the housing. The outer surface of the housing is provided with an adhesive surface for adhering to a vehicle.

[0039] From the above content, it is not difficult to conclude that the housing can achieve integrated protection for the RFID chip and the RFID antenna, avoiding direct exposure of the RFID chip and the RFID antenna, and preventing damage during direct contact with the outside world. At the same time, since the RFID tag needs to be installed on a vehicle, the adhesive surface of the housing facilitates the adhesion of the RFID tag. And when the RFID tag is damaged and needs to be replaced, the RFID chip and the RFID antenna installed in the housing are also convenient to disassemble. In addition, the housing can be made of plastic, rubber, ABS, polytetrafluoroethylene, and such materials do not affect the transmission of the RFID antenna signal, protecting the RFID chip and the RFID antenna while ensuring the stability of signal transmission.

[0040] And as Figure 1 shown, the management module 7 includes: an information collection module, an analysis and judgment module, and a control module. The information collection module is communicatively connected or wired to the vehicle sensing device 6, the imaging device 3, and the RFID communication device. The analysis and judgment module is communicatively connected or wired to the information collection module and the control module. The analysis and judgment module stores vehicle information and is used to judge the vehicle information obtained by the information collection module against the stored vehicle information, and send an instruction to the control module according to the judgment result. The control module is communicatively connected or wired to the analysis and judgment module and the access control system 5, and is used to control the opening and closing of the access control system 5 according to the comparison result of the vehicle information obtained by the RFID reading device and the imaging device 3 with the stored vehicle information by the analysis and judgment module.

[0041] From the above content, it is not difficult to conclude that the management module 7 stores vehicle information that can enter. This is to facilitate the management module to compare the vehicle information obtained through the camera device 3 and the RFID reading device with the vehicle information in the management module 7, and to determine whether the parked vehicle is the vehicle stored in the management module 7. In order to complete the judgment on whether the vehicle can enter and prevent some foreign or illegal vehicles from entering. When the vehicle meets the entry requirements, the control module controls the access control system 5 to open to facilitate the vehicle's entry. In some embodiments, the control module can use a single-chip microcomputer or a PLC, and the management module 7 can use a computer or the like as a medium for storing customer information. The single-chip microcomputer and the PLC have low costs and mature technologies, which are convenient for the production and popularization of the intelligent vehicle access management device. And in this embodiment, the management module 7 includes: an information collection module, an analysis and judgment module, and a control module. The information collection module is communicatively connected or wired to the camera device 3 and the RFID communication device. The analysis and judgment module is communicatively connected or wired to the information collection module and the control module, stores vehicle information, and is used to judge the vehicle information obtained by the information collection module with the stored vehicle information, and issue an instruction to the control module according to the judgment result.

[0042] In some embodiments, the intelligent vehicle access management device further includes: a display device. The display device is communicatively connected or wired to the management module 7 and is used to display the vehicle information received by the management module 7.

[0043] From the above content, it is not difficult to conclude that the display device can display and feedback the situation of the management module 7, realizing the interaction with the vehicle driver, so that the vehicle driver can obtain the result in time. Especially when the intelligent vehicle access management device is applied to some places that are not open to the public, the display device can provide information to the vehicle driver in time, enabling the vehicle driver to make timely adjustments according to the judgment result displayed by the display device. The display device can use an LED display screen or the like, which can emit light at night for the vehicle driver to read the information easily. This can avoid congestion at the vehicle entrance and exit. Of course, in some embodiments, the intelligent vehicle access management device further includes: a voice broadcast device. The voice broadcast device is communicatively connected or wired to the management module 7 and is used to broadcast the vehicle information displayed by the display device. Through the combined use of the voice broadcast device and the display device, while the display device displays the vehicle information, the voice broadcast device can broadcast the vehicle information and the comparison result. This is convenient for the vehicle driver to obtain information visually and auditorily at the same time, increasing the channels for the vehicle driver to obtain parking information and facilitating the vehicle driver to be reminded to make the next move according to the feedback. This can avoid some vehicle drivers from being unable to see the text information on the display device clearly, resulting in failure to make corresponding operations in time and causing congestion at the vehicle entrance and exit.

[0044] In addition, in some embodiments, the intelligent vehicle access management device further includes: an alarm device. The alarm device is communicatively connected or wired to the management module 7 and is used to give an alarm when the display device shows a vehicle in violation.

[0045] From the above content, it is not difficult to conclude that since the intelligent vehicle access management device can obtain vehicle information through the in-vehicle RFID tag. Therefore, when the vehicle information recorded in the RFID tag does not match the license plate information, or when only the license plate is recognized for the registered vehicle information but the RFID tag information is not detected, it indicates that the vehicle is a cloned vehicle. At this time, the vehicle is a vehicle in violation, and the alarm device can give an alarm in time. And when a vehicle that does not meet the entry requirements occupies the vehicle entrance and exit for a long time, the alarm device can also give an alarm in time, avoiding the situation where other vehicles cannot enter or exit normally due to a vehicle occupying the vehicle entrance and exit for a long time. This protects the rights and interests of normal users and at the same time prevents the entry of foreign or illegal vehicles.

[0046] Furthermore, as Figure 1 , Figure 2 shown, in some embodiments, the vehicle sensing device 6 can be a geomagnetic sensing device 61. The geomagnetic sensing device 61 is communicatively connected or wired to the management module 7 and is used to identify whether a vehicle has passed by, and to activate the camera device 3 through the management module 7.

[0047] From the above content, it is not difficult to conclude that when the vehicle travels to the geomagnetic sensing device 61, the geomagnetic sensing device 61 transmits the vehicle signal to the management module 7 to wake up the camera device 3. The camera device 3 is in a standby state when there is no vehicle traveling to the vehicle entrance and exit, avoiding the camera device 3 working for a long time, reducing the energy consumption and usage cost of the intelligent vehicle access management device. And the geomagnetic sensing device is laid on the ground, directly identifying the vehicle, and will not be affected by environmental factors such as light to affect the recognition accuracy. Of course, to meet the recognition of whether there is a vehicle at the vehicle entrance and exit, radar or infrared sensing can also be used instead of the geomagnetic sensing device 61.

[0048] Finally, in some embodiments, the intelligent vehicle access management device further includes: a waterproof electrical box. The RFID reading device is arranged in the waterproof electrical box.

[0049] From the above content, it is not difficult to conclude that some parking lots are set up outdoors, so the RFID reading device is exposed to the outside. When it rains, for example, the RFID reading device will be eroded by rainwater. When the waterproof measures of the RFID reading device are not good, the RFID reading device will short-circuit, thus affecting the use of the intelligent vehicle access management device. The waterproof electrical box can provide waterproof protection for the RFID reading device, avoiding damage to the RFID reading device due to factors such as rainwater during daily use, and ensuring the daily use of the intelligent vehicle access management device.

[0050] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present utility model. It should be understood that the above are only specific embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
