[0034] As an embodiment, the model of industrial computer is B10J model embedded industrial computer.

[0035] Industrial computer is connected with 4G router through network port, realizes network communication and can transmit data through network, RFID integrated reader is connected with industrial computer through network, RFID integrated reader reads the information of electronic tag pasted to mine car body in the working area of transmitting antenna and transmits information to cloud platform through network, and camera is connected with industrial computer through network port, and the vehicle entering the mining area is snapped together, and the image information collected is transmitted to cloud platform through network.

[0036] The display screen control board is connected with the relay control board through the interface of 485 conversion network port. The display screen control board has a communication module of 485 conversion network port inside, which can realize protocol conversion. The data can be converted from Modbus RTU protocol to Modbus TCP protocol, so that the display screen can receive information instructions of the industrial computer through the Modbus TCP protocol. The display screen control board is connected with the display screen HUB through a large flat cable. The display screen HUB is connected with the LED display screen through a flat cable.

[0037] Meanwhile, the display screen control board is connected with the text-to-audio module through the DB9 serial port, so that the text information received by the display screen control board can be converted into audio information.

[0040] The solar power controller is connected with the relay control board. The solar panel is combined and connected with the storage battery and the solar power controller. The relay control board controls the output of the power supply through two paths of DI+DO. One path is connected with the 12V-to-5V power controller and the text-to-audio module, respectively, to provide 12V power supply. The other path is connected with the camera to provide 12V power supply.

[0042] By installing RFID integrated reader at the entrance and exit, using RFID technology, using the wireless radio frequency mode of RFID for non-contact automatic identification, obtaining vehicle identity information, solving the problem of difficult plate recognition caused by dust covering the license plate, improving the accuracy and speed of identification, and using LED display screen and voice broadcast mode, the staff and vehicle owner can directly understand the mine car situation in the harsh environment of the mine area, improving the efficiency and accuracy of the mine vehicle management.

[0043] In the embodiment, the working process when the mine vehicle enters and exits the identification area includes:

[0044] When the empty car enters the mine area for the first time, the information is input to the background of the registration center: the input information includes the license plate number, the owner's name, etc.

[0045] At the same time, the staff pastes the RFID electronic tag containing the license plate number information at the designated position.

[0046] The driver goes to the designated loading point, and after loading, the driver does not need to get off the car, and when the RFID electronic tag pasted on the mine car enters the working area of the RFID integrated reader transmitting antenna, the license plate number information can be quickly obtained,

[0047] Through the cloud platform, the information is sent to the industrial computer to trigger the LED display screen to display the vehicle information, and the audio will broadcast the vehicle information displayed on the LED display screen. The displayed vehicle information specifically includes: license plate number, vehicle attendance frequency, and vehicle loading status.

[0048] As an embodiment, the vehicle attendance frequency is counted by combining RFID radio frequency identification and image recognition. The RFID reader at the entrance and exit collects the vehicle information of the electronic tag of the vehicle, and triggers the camera to capture the image of the mine car. The collected vehicle information and the captured mine car image are transmitted to the background data processing center. The background analyzes the loading rate of the mine car through image recognition. If the loading rate is zero, the vehicle attendance frequency is not added; if the loading rate is not 0, the vehicle attendance frequency is added by 1.

[0049] As an embodiment, the vehicle loading status is calculated by identifying the vehicle image captured by the camera through a deep learning algorithm. The specific steps are as follows:

[0050] 1. Capture the image of the mine car loading state entering and exiting the mine through the camera;

[0051] 2. Input the real-time captured image of the mine car entering and exiting the mine into the pre-established model to determine the loading rate state;

[0052] 3. Determine whether the captured image contains the complete mine car loading cargo area range and the vehicle box contour.

[0053] 4. Image processing is performed on the image containing the complete mine car loading cargo area range and the car box contour;

[0054] 5. The total sum of empty pixel depth F of the cargo area in the processed mine car loading cargo image and the total sum of pixel depth W of the entire mine car box are determined by a deep learning algorithm, and the mine car loading rate is calculated as (W-F) / W*100%.

[0055] Wherein, the specific steps for establishing the model are:

[0056] 1. Collect a large number of images of different types of mine cars loaded with cargo in the mining area, obtain the first image of the cargo area of different types of mine cars, and obtain the second image of the car box of different types of mine cars as training sample images.

[0057] 2. Select the convolutional neural network (CNN) architecture of the deep learning model, extract the features of the mine car image through the convolutional layer and the pooling layer, and reduce the dimension and abstract the extracted features through the pooling operation, arrange the key information in the image, and complete the image recognition.

[0058] 3. Image preprocessing is performed on the image containing the complete mine car box image: the image of the car box loaded with cargo or the empty car box image is preprocessed by scaling, cropping, graying, and normalizing the image;

[0059] 4. The processed mine car image is simulated and trained, the model parameters are continuously optimized through the back propagation algorithm, and a model capable of identifying the mine car loading rate is generated.

[0060] Using RFID technology combined with a camera to capture images, the captured photos can be analyzed and judged using algorithms, so that the staff can obtain the license plate number, vehicle attendance frequency, and vehicle loading status in real time without going to the harsh site of the mining area for mine car monitoring and management. At the same time, it also solves the problem of being unable to accurately judge the actual loading condition of the mine car in real time, and improves the overall work efficiency.

[0061] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
