All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic structural diagram of a vehicle inquiry system according to an embodiment of the present invention. As shown in fig. 1, the vehicle inquiry system includes: the system comprises an image acquisition device 1, at least one RFID (radio frequency identification) tag 2, a server 3 and a terminal 4, wherein each RFID tag 2 comprises a reader 21 and at least one electronic tag 22, and one electronic tag 22 is installed in each parking space.
The image acquisition device 1 is used for acquiring a parking space image and sending the parking space image to the server 3.
The server 3 is used for identifying the vehicle identification and the parking space identification in the parking space image and storing the identified vehicle identification and the identified parking space identification in an associated manner. When a vehicle query request carrying a target vehicle identifier and sent by the terminal 4 is received, querying a target parking space identifier of a parking space where the target vehicle is located according to the information stored in association with the target vehicle identifier, and sending the target parking space identifier to the readers 21 of all the RFID radio frequency tags 2; the terminal is also used for receiving GPS information fed back by the reader 21 and feeding back the GPS information to the terminal 4;
the reader 21 is configured to forward the received target parking space identifier to all the electronic tags 22 under the RFID radio frequency tags 2, receive GPS information corresponding to the parking space identifier information returned by the electronic tags 22 in which the target parking space identifier is stored, and feed the GPS information back to the server 3.
Specifically, the image acquiring device 1 is installed outside a parking space, and after a vehicle is parked in the parking space, the image of the parking space is captured, and it is ensured that the image of the parking space includes a license plate identifier such as a license plate number and a parking space identifier, where the parking space identifier may be set in the parking space by suspending a sign or printing on the ground in front of the parking space, and the image acquiring device 1 may be a camera or other similar monitoring device, which is not particularly limited in this embodiment of the present invention. The image acquisition device 1 acquires the parking space image and then sends the parking space image to the server 3.
After receiving the parking space image sent by the image obtaining device 1, the server 3 identifies a vehicle identifier of a parked vehicle and a parking space identifier of a parking space in the parking space image, and performs associated storage on the vehicle identifier and the parking space identifier, where the storage may be based on a local database, or may be based on non-local storage, and the like, and the embodiment of the present invention is not particularly limited thereto. When a user needs to inquire the position of the vehicle, a vehicle inquiry request carrying a target vehicle identifier is sent to the server 3 through an APP (application), a WeChat applet and a WeChat public number on the terminal 4 or through an inquiry website. When the server 3 receives the vehicle query request, the server may obtain a corresponding target parking space identifier from the target vehicle identifier in the vehicle query request in the data related to the vehicle identifier and the parking space identifier stored in the associated manner, and further send the obtained target parking space identifier to all readers 21 of the RFID radio frequency tags 2 arranged in the parking lot.
After each reader 21 receives the target parking space identifier, the target parking space identifier is sent to all the radio frequency tags 22 under the RFID radio frequency tag 2 to which the reader 21 belongs. The radio frequency tags 22 are installed in each parking space in the parking lot, and correspondingly, the parking space identification of the parking space and the GPS information of the parking space are stored in each radio frequency tag 22. After receiving the target parking space identifier sent by the reader 21, each rf tag 22 compares the target parking space identifier with the parking space identifier stored in itself, and if the comparison finds that the received target parking space identifier is the same as the parking space identifier stored in itself, the GPS information of the parking space stored in itself is fed back to the reader 21, and the reader 21 then feeds back the GPS information of the parking space to the server 3.
As shown in fig. 2, the electronic tag 22 in the RFID tag 2 is composed of a transceiver antenna, a modulation module, a demodulation module, a microprocessor, and a storage module, where fixed data is stored in the storage module, and the fixed data is GPS information and parking space identification information of a parking space. The reader 21 is composed of a receiving and transmitting antenna, a modulation module, a demodulation module, a microprocessor, a storage module and an IO interface, and the reader 21 performs bidirectional communication with the server 3 based on the IO interface.
After receiving the GPS information of the parking space, the server 3 may feed back the GPS information to the terminal 4, so that the user may search for his vehicle according to the GPS information.
According to the vehicle inquiry system provided by the embodiment of the invention, the parking space identification and the vehicle identification are acquired and stored through the parking space image, the corresponding parking space identification is acquired through the vehicle identification when the target vehicle is inquired, and the GPS information of the parking space is further acquired through the electronic tag 22 arranged on the parking space, so that the inquiry of the position of the vehicle by a user is realized, and the problem that the vehicle cannot be found after the vehicle is parked is avoided.
On the basis of the embodiment, the parking space image further comprises a floor mark.
Correspondingly, the server 3 further obtains the floor identifier from the parking space image, stores the floor identifier in the vehicle identifier and the parking space identifier in an associated manner, queries the target floor identifier of the floor where the target vehicle is located and the target parking space identifier of the parking space where the target vehicle is located according to the information stored in the associated manner for the target vehicle identifier when receiving the vehicle query request carrying the target vehicle identifier sent by the terminal 4, and sends the target parking space identifier to the readers 21 of all the RFID radio frequency tags 2 corresponding to the target floor identifier.
Specifically, there are some parking lots with multiple floors, and therefore, it is necessary to identify the floors in the parking lot while setting the parking space identifiers. The parking space image acquired by the image acquiring device 1 includes the vehicle identifier and the parking space identifier of the parking space, and correspondingly includes the floor identifier of the parking space. Correspondingly, the server 3 also recognizes the floor identification, and stores the recognized floor identification in association with the vehicle identification and the parking space identification which are recognized together.
When the server 3 receives the vehicle query request carrying the target vehicle identifier sent by the terminal 4, because the stored associated information already contains the floor identifier of the target vehicle, the corresponding target floor identifier and the target parking space identifier are correspondingly obtained according to the target vehicle identifier, and the target parking space identifier is only sent to the readers 21 of all the RFID radio frequency tags 2 on the floor corresponding to the floor identifier for vehicle query.
Further, a floor identifier is stored in the electronic tag 22, and accordingly, the information fed back to the reader 21 by the electronic tag 22 and fed back to the server 3 by the reader 21 may further include the parking space identifier and the floor identifier associated with the GPS information, so that the server 3 may directly forward the received information when feeding back the information to the terminal 4, and does not need to merge the locally stored parking space identifier and floor identifier with the received GPS information and then send the merged information to the terminal 4.
The vehicle inquiry system provided by the embodiment of the invention further acquires the floor identification, and only sends the target parking space identification to the reader 21 of the corresponding floor, so that more communication, processing and other related system resources can be saved in the inquiry process.
On the basis of the embodiment, the vehicle inquiry system comprises the vehicle sensing device 5, the vehicle sensing device 5 is used for sensing parking of a vehicle in a parking space, and when the vehicle is sensed to park in the parking space, the image acquisition device 1 is triggered to acquire a parking space image and send the parking space image to the server 3.
Specifically, the parking space sensing device 5 corresponds to the image acquiring device 1, and when the parking space sensing device 5 senses that a vehicle is parked at a parking space, the image acquiring device 1 corresponding to the parking space sensing device 5 is triggered to acquire a parking space image, and the parking space image is sent to the server 33. The triggering time may be that the vehicle stops, that is, the vehicle is triggered, but for some special situations, such as a lateral parking space, there may be a situation that the vehicle only passes by but does not stop, and therefore, the image capturing device 1 may be triggered to capture the parking space image within a delay time after the vehicle stops, which may be several seconds or several minutes, so as to avoid unnecessary operations.
The vehicle inquiry system provided by the embodiment of the invention further limits the time for the image acquisition device 1 to acquire the parking space image, and acquires the parking space image only when the vehicle stops, so that the acquisition operation of the image acquisition device 1 is more targeted, and the system resource waste caused by blind timing acquisition and other modes is avoided.
Further, the vehicle sensing device 5 is further configured to sense exit of a vehicle at a parking space, and when sensing exit of the vehicle, trigger the image acquiring device 1 to acquire a parking space image and send the parking space image to the server 3;
correspondingly, the server 3 is further configured to store the received parking space image, compare the received parking space image with the stored parking space image, identify the vehicle identifier of the newly added vehicle and the parking space identifier of the parking space where the newly added vehicle is located when the received parking space image has a newly added vehicle relative to the stored parking space image, store the identified vehicle identifier and the parking space identifier in association, and delete the vehicle identifier and the parking space identifier stored in association when the received image has a reduced vehicle relative to the stored parking space image; the server 3 is further configured to replace the stored parking space image with the received parking space image.
Specifically, the vehicle sensing device 5 senses not only the parking of the vehicle but also the exit of the vehicle, and when sensing the exit of the vehicle, the image capturing device 1 is also triggered to capture the parking space image and transmit the parking space image to the server 3. And when the server 3 receives the parking space image, comparing the received parking space image with the parking space image which is stored locally and received last time. Since the parking space image is only obtained when the sensing device 5 senses that the vehicle is parked or driven out, it can be determined that the received parking space image is the parking space image when the vehicle is parked when the parking space image stored in the server 3 is the parking space image when the vehicle is driven out, and the received parking space image is the parking space image when the vehicle is driven out when the parking space image stored in the server 3 is the parking space image when the vehicle is driven out. When the received parking space image has new vehicles relative to the stored parking space image, the vehicle identification of the new vehicles and the parking space identification of the parking space where the new vehicles are located are identified, the identified vehicle identification and the parking space identification are stored in an associated mode, and when the received image has fewer vehicles relative to the stored parking space image, the vehicle identification and the parking space identification stored in an associated mode are deleted. Because this extraction of vehicle sign and parking stall sign is based on the change part of parking stall image and confirms, consequently the parking stall image that image acquisition device 1 acquireed can include the parking stall image of a plurality of parking stalls, one promptly image acquisition device 1 can correspond a plurality of parking stalls, only need to ensure that the parking stall sign and the vehicle sign on every parking stall of the clear demonstration of the parking stall image ability that acquires can. And after the comparison of the images and the extraction and deletion of the identification are completed, the server 3 replaces the stored parking space image with the newly received parking space image for subsequent use.
The vehicle inquiry system provided by the embodiment of the invention further limits that the image acquisition device 1 can acquire the parking space images when the vehicle is driven out, the server 3 circularly stores and replaces the parking space images, and extracts and deletes information by comparing the newly received parking space images with the stored parking space images, so that the image acquisition device 1 can cover more parking spaces, more image acquisition devices 1 can be saved, and the cost for setting the vehicle inquiry system provided by the invention is reduced for users.
On the basis of the above embodiment, the information fed back to the reader 21 by the electronic tag 22 and fed back to the server 3 by the reader 21 may further include the parking space identifier associated with the GPS information, so that the server 3 may directly forward the received information when feeding back the information to the terminal 4, and does not need to merge the locally stored parking space identifier and the received GPS information and then send the merged parking space identifier and the received GPS information to the terminal 4.
On the basis of the above embodiment, the terminal 4 is further configured to navigate based on the received GPS information, so that the user can find his vehicle faster and more conveniently according to the received GPS information and the like.
