The embedded processor 8 makes a legality judgment based on the preset parking lot management logic data relationship. If the swiped card is legal when entering the parking lot or is legal when exiting the parking lot and has been instructed, a signal is given to the channel gate machine 26 through the relay output 25 to open the gate.

The output end of the logic control module 80 is electrically connected to the remote management PC 21 via the Ethernet port 20 .

[0033] The working principle of the parking lot parking space management control device based on image recognition technology of this embodiment is as follows: the on-duty personnel logs into the system, and the embedded processor 8 retrieves the data in the flash memory 3 or the hard disk 4 for authority authentication. If the authentication is passed, the embedded processor 8 displays the on-duty personnel information on the display 17 through the Vga driver 16, and initializes the display interface of the display 17; when the vehicle enters the parking lot, the card is swiped, and the entrance card reading module 24 transmits the card internal code to the embedded processor 8 through the RS232 interface / RS485 interface 22. The embedded processor 8 makes a legality judgment based on the pre-set parking lot management logical data relationship, and drives the LED display screen 7 and the speaker 15 to prompt the entry information. If the card is legal, it is output to the channel gate 26 through the relay output 25 to open the gate. The embedded processor 8 will drive the video processing module 9 to capture the vehicle entry photo of the video stream of the video A / D2 of the camera 1, and store the vehicle entry record containing information such as the card number, entry time, and photo file name together with the photo file in the flash memory 3 or the hard disk 4.

[0034] When the vehicle exits the parking lot, the card is swiped, and the exit card reader module 23 transmits the card internal code to the embedded processor 8 through the RS232 interface / RS485 interface 22. The embedded processor 8 makes a legality judgment based on the preset parking lot management logic data relationship. If it is legal, it performs logic and data processing according to the system software settings. At the same time, the embedded processor 8 drives the video processing module 9 to capture the vehicle exit photo of the video stream of the video A / D of the camera 11, and displays the vehicle information (card number, license plate number, entry time, exit time, receivable amount, actual amount collected, photos of vehicles entering and leaving the parking lot, etc.) on the display 17 through the Vga driver 16, and prompts the charging amount, safe trip, etc. through the LED display 7 and the speaker 15, waiting for the on-duty personnel's instructions. The on-duty personnel operate according to the following situations: A. After the fixed user vehicle verifies that the entry and exit images are consistent, click the release button on the system interface through the USB mouse 19 or keyboard 27, and the embedded processor 8 gives the relay output 25 The channel gate 26 relay signal opens the gate, the embedded processor 8 gives the video processing module 9 a command to display the camera 11 and the video stream of the camera 11 on the display 17, and the embedded processor 8 stores the parking record data of this time on the flash memory 3 or the hard disk 4; B. When a temporary vehicle leaves the vehicle, the duty personnel selects the vehicle model (large truck, small car, military and police car, etc.) according to the vehicle characteristics through the USB mouse 19, and the embedded processor 8 calculates the parking fee amount according to the vehicle model, parking time, charging standards, etc. The duty personnel needs to modify the actual amount collected through the keyboard 27 according to the actual charging amount. The embedded processor 8 automatically initializes the actual amount collected to the amount to be collected and the input license plate number. After the charging is completed and the entry and exit images are verified to be consistent, the embedded processor 8 gives the channel gate 26 a relay signal through the relay output 25 to open the gate, and the embedded processor 8 gives the video processing module 9 a command to display the video stream of the camera 10 on the display 17, and the embedded processor 8 stores the parking record data of this time on the flash memory 3 or the hard disk 4. After the vehicle swipes its card to exit the vehicle, while waiting for release, if the vehicle is not allowed to exit the vehicle for some reason, the on-duty personnel can select the cancel release button on the system interface through the USB mouse 19 or keyboard 27 to cancel the operation, and wait until the vehicle can exit the vehicle, and then swipe the card to exit the vehicle according to the exit process.

[0035] For a parking lot system with multiple entries and exits, one of the embedded parking lot fee management devices can be set as a server, and the embedded parking lot fee management devices at other entrances and exits access the data in the flash memory 3 or hard disk 4 in the server through the Ethernet port 20. All entry and exit data (including vehicle entry and exit photos) are also centrally stored and managed in the flash memory 3 or hard disk 4 of the server; the parking lot manager operates a remote management PC in the office to access and edit the data in the flash memory 3 or hard disk 4 through the Ethernet port 20.

[0036] The on-duty personnel can use the USB mouse 19 and keyboard 27 to issue cards, authorize, report loss, recharge, query and print vehicle parking records, fee statistics and other operations through the software interface displayed on the display 17; in addition, the embedded parking lot fee management device can also add a set of card reading modules in the on-duty fee booth, without installing the USB mouse 19 and keyboard 27, and perform vehicle fee release, gate opening and other operations by swiping the card.

[0037] The embedded parking lot fee management device can also be used in conjunction with an existing controller (without video stream capture function), only as a video stream capture photo storage of a camera 10, and display the data information uploaded by the controller (card number, license plate number, entry time, exit time, receivable amount, actual amount collected, photos corresponding to the photo names of vehicles entering and exiting, etc.), to achieve embedded management of the parking lot.

[0038] To sum up, the parking lot parking space management and control device based on image recognition technology of the present invention uses an input module for uploading radar ground sensing status data, and combines the license plate data recorded in the logic control module. When the radar ground sensing status data input from the input module matches the license plate data recorded in the logic control module, the logic control module controls the driving ground lock to open so that the chassis of the new energy vehicle will not touch the ground lock. It can achieve precise control of the lifting of the ground lock, avoid accidents caused by the ground lock touching the chassis of the new energy vehicle, reduce the failure rate of the system, thereby improving the safety of the entire parking space management and control device, effectively overcoming the various shortcomings in the prior art and having a high industrial utilization value.

[0039] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention.
