Description

Technical Field

[0001] This invention relates to the field of positioning confirmation technology, and in particular to a method, apparatus, equipment and storage medium for positioning confirmation of unloading vehicles. Background Technology

[0002] In traditional unloading vehicle positioning and confirmation technology, the silo unloading trolley is remotely set to automatic positioning. To avoid positioning errors, a camera is installed on the trolley, and a positioning number sign is installed at the loading point. After the unloading trolley is in place, the camera is exactly at the loading point, and the operator needs to manually operate the monitoring screen to confirm the fixed point.

[0003] During use, because operators also need to manage other equipment, the unloading trolley sometimes neglects to check the positioning screen when positioned at a distance. Furthermore, when the monitoring screen is displayed in another area, switching between the operating and monitoring screens is necessary, making operation and video viewing inconvenient and inefficient for operators. Therefore, a method for real-time and efficient positioning confirmation of the unloading trolley is needed. Summary of the Invention

[0004] This invention provides a method, apparatus, equipment, and storage medium for confirming the positioning of unloading vehicles, so as to achieve real-time and efficient positioning confirmation of unloading vehicles.

[0005] In a first aspect, embodiments of the present invention provide a method for confirming the positioning of an unloading vehicle, the method comprising:

[0006] The point mapping relationship of each material drop point is determined in advance, and the preset arrival point of the unloading car is determined; the point mapping relationship is used to represent the mapping relationship of the physical position of each material drop point on the Gray busbar; the preset arrival point is the material drop point that the preset unloading car will arrive at.

[0007] Obtain the current position parameters of the unloading vehicle during its movement;

[0008] Based on the point mapping relationship, the current position parameters are compared with the preset arrival point. If the current position parameters and the preset arrival point are the same, a video window will pop up on the front-end page to confirm the unloading vehicle position according to the current position parameters.

[0009] Secondly, embodiments of the present invention also provide a positioning confirmation device for an unloading vehicle, the device comprising:

[0010] The pre-arrival location determination module is used to determine the pre-set point mapping relationship of each material drop point and to determine the preset arrival point of the unloading vehicle; the point mapping relationship is used to represent the mapping relationship of the physical position of each material drop point on the Gray busbar; the preset arrival point is the preset material drop point to which the unloading vehicle will arrive.

[0011] The current position determination module is used to obtain the current position parameters during the movement of the unloading vehicle;

[0012] The location confirmation module is used to compare the current location parameters with the preset arrival point based on the point mapping relationship. If the current location parameters and the preset arrival point are the same, a video window will pop up on the front-end page to confirm the location of the unloading vehicle.

[0013] Thirdly, embodiments of the present invention also provide an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the unloading vehicle positioning confirmation method as described in any of the embodiments of the present invention.

[0014] Fourthly, embodiments of the present invention also provide a storage medium for storing computer-executable instructions, which, when executed by a computer processor, are used to perform the unloading vehicle positioning confirmation method as described in any of the embodiments of the present invention.

[0015] The technical solution of this invention pre-calibrates the positions of each material drop point on the Gray busbar, determines the point-position mapping relationship, obtains the actual position of the unloading vehicle on the Gray busbar during its movement, and compares the actual position of the unloading vehicle with the preset arrival point position based on the point-position mapping relationship. When the actual position of the unloading vehicle and the preset arrival point position are the same, it indicates that the unloading vehicle has arrived. Automatic and real-time confirmation of the unloading vehicle's arrival is achieved by popping up a video window on the front-end page, thereby improving the efficiency and accuracy of unloading vehicle position confirmation in industrial scenarios.

[0025] Example 1

[0026] Figure 1 This is a flowchart illustrating a method for confirming the positioning of an unloading vehicle according to Embodiment 1 of the present invention. This embodiment is applicable to situations requiring the confirmation of unloading vehicle positioning. This method can be executed by an unloading vehicle positioning confirmation device, which can be implemented in hardware and / or software. This device can be configured in any electronic device with network communication and computing capabilities. Figure 1 As shown, the method includes:

[0027] S110. Determine the pre-set point mapping relationship of each material drop point, and determine the preset arrival point of the unloading vehicle.

[0028] In this embodiment, the point mapping relationship is the mapping relationship of the physical location of each material drop point on the Gray busbar, and the preset arrival point is the material drop point on the Gray busbar that the unloading car needs to reach.

[0029] Specifically, the point mapping relationship is determined based on the sequence number and location of each material drop point. The target material drop point that the unloading vehicle needs to reach can be determined by responding to the preset arrival point of the external input.

[0030] Optionally, the unloading vehicle is equipped with an image acquisition device, the unloading vehicle travels along the Gray busbar path, the material drop point is equipped with a position signal point, and the Gray busbar connects the position signal points of each material drop point.

[0031] In this embodiment, each material drop point is configured with a position signal point, and the position signal points of each material drop point are connected through a Gray bus. The position signal points can be used to determine the position information of the unloading vehicle. By detecting the position signal points on the Gray bus, it is determined whether the unloading vehicle has reached the loading point corresponding to the preset arrival point, thus avoiding reliance on vague "visual identifiers".

[0032] Optionally, determine the pre-set point mapping relationship for each material drop point, including:

[0033] Determine the physical location of each material drop point on the Gray busbar, determine the point-to-point mapping relationship based on the material drop point number and physical location, and write the point-to-point mapping relationship into a pre-set register address.

[0034] In this embodiment, by calibrating the position of each material drop point number on the Gray busbar, a point mapping relationship is generated, and the register address of each material drop point position is set and written into the corresponding register address.

[0035] S120. Obtain the current position parameters during the movement of the unloading vehicle.

[0036] In this embodiment, the current position parameter is the real-time physical position of the unloading vehicle on the Gray busbar during its movement.

[0037] Specifically, when the unloading truck moves to a new location, the on-board scanner can be used to scan the position of the Gray bus in real time, scanning the position signal points on the Gray bus. The position signal points can be preset to be 1 or 0. If the position signal point of the dropping point is 1, it means that the unloading truck has arrived at the current dropping point. If the position signal point of the dropping point is 0, it means that the unloading truck is not at the current dropping point. Furthermore, based on the value of the position signal point, the real-time physical position of the unloading truck on the Gray bus during the movement is obtained, the current position parameters are determined, and the current position parameters are stored in the register.

[0038] S130. Based on the point mapping relationship, compare the current position parameters with the preset arrival point. If the current position parameters and the preset arrival point are the same, pop up a video window on the front-end page to confirm the unloading vehicle position according to the current position parameters.

[0039] In this embodiment, the register address of the current position parameter is determined based on the point mapping relationship, wherein the preset arrival point is stored in a configuration file or register. After obtaining the current position parameter, the preset arrival point is read through the register, and the current position parameter and the preset arrival point are compared.

[0040] In this embodiment, by comparing the current position parameter with the preset arrival point, it can be directly determined whether the current position parameter is equal to the preset arrival point, and thus determine whether the unloading vehicle has arrived at the designated point. For example, if the preset arrival point, the pre-stored register address of the loading point of silo 3, is 1500, and the current position parameter is read as 1500, then it is determined that the unloading vehicle has arrived at the designated dropping point.

[0041] Optionally, after comparing the current location parameters with the preset arrival point, the following steps are taken:

[0042] If the current position parameters are determined to be the same as the preset arrival point, a stop command is generated to control the unloading vehicle to stop moving.

[0043] In this embodiment, specifically, a comparison instruction can be used to compare the register address of the current position parameter with the register address of the preset arrival point. If the current position parameter and the preset arrival point are the same, it means that the unloading vehicle has reached the designated landing point. Then, a stop instruction is output after the "arrival signal" to drive the braking unit of the unloading vehicle motor to control the unloading vehicle to stop moving.

[0044] In this embodiment, in the unloading vehicle positioning scenario, generating a parking command when "the current position parameters are the same as the preset arrival point" is the core control link to ensure the accurate parking of the unloading vehicle, taking into account both the real-time positioning of the unloading vehicle (avoiding overshoot) and reliability (preventing accidental stopping).

[0045] Optionally, if it is determined that the current location parameters are the same as the preset arrival point, the following options are also included:

[0046] If the current location parameters are determined to be the same as the preset arrival point, a pop-up pulse signal is generated.

[0047] Based on the pop-up pulse signal, a video window will automatically pop up on the front-end page to confirm the location of the unloading vehicle.

[0048] In this embodiment, the current position parameters are first compared with the preset arrival point. If the comparison determines that the current position parameters and the preset arrival point are the same, a pop-up pulse signal is generated as a switch to trigger the pop-up. When the upper machine program detects the pop-up pulse signal, a video window automatically pops up to display the loading point positioning screen for confirmation.

[0049] In this embodiment, the core interactive logic from location determination to pop-up triggering can solve the problems of operators ignoring the check and cumbersome screen switching, thereby improving the efficiency and accuracy of unloading vehicle location confirmation in industrial scenarios.

[0050] Optionally, the current location parameters are compared with the preset arrival point. If the current location parameters and the preset arrival point are the same, a video window pops up on the front-end page to confirm the unloading vehicle's positioning based on the current location parameters, including:

[0051] Compare the current location parameters with the preset arrival point;

[0052] If the current location parameters are the same as the preset arrival point, the image of the current location of the unloading vehicle is obtained through the image acquisition device. A video window is generated based on the current location image and the current location parameters, and the video window pops up on the front-end page to confirm the location of the unloading vehicle.

[0053] In this embodiment, the image acquisition device can be a camera or monitoring device on the unloading vehicle, and the current position image is an image that can represent the current bin number or the material drop point number.

[0054] By comparing the current position parameters of the unloading truck transmitted from the Gray bus with the preset arrival point stored in the register in real time, when the current position parameters and the preset arrival point are the same, the image acquisition device is triggered to acquire a signal. The image acquisition device on the unloading truck is automatically controlled to capture the current position image. The current position image and the current position parameters are used to generate a multi-source information video window containing the image and the measured position. The video window is automatically popped up on the front-end page, allowing operators to quickly check the positioning accuracy of the unloading truck in the picture of the sign and the bin. This avoids operators frequently switching the picture and improves the positioning efficiency of the unloading truck.

[0055] Optionally, the current location parameters are compared with the preset arrival point. If the current location parameters and the preset arrival point are the same, a video window pops up on the front-end page to confirm the unloading vehicle's positioning based on the current location parameters, including:

[0056] Get the current time information;

[0057] The video window is captured according to a preset delay time to obtain positioning image data;

[0058] The location image data and current time information are saved.

[0059] In this embodiment, the preset delay time refers to the interval during which the video window is captured after it pops up. The preset delay time can be set in advance, such as 3s or 5s.

[0060] Specifically, the current location parameters are compared with the preset arrival point. If the current location parameters and the preset arrival point are the same, the front-end page will automatically pop up a video window containing the current landing point of the unloading vehicle. After the pop-up window appears, a screenshot of the video window will be automatically taken according to the preset delay time to avoid blurring, so as to obtain stable positioning image data of the unloading vehicle. The positioning image data is then bound with the current time information and the current location parameters and saved according to the rules.

[0061] In this embodiment, a complete traceability loop from "location confirmation to delayed screenshot to data archiving" is established. Through precise time control and data association, the effectiveness of the location image is ensured, blurry images are avoided at the moment of arrival, and a traceable record is formed.

[0062] It should be noted that the process in this embodiment, from "location triggering to delayed screenshotting and then to structured saving," not only ensures the validity of the location image but also forms a traceable and complete record through the binding of time, location, and image. Operators only need to confirm the pop-up window; subsequent screenshotting and archiving are fully automated, significantly reducing manual operations and adapting to the needs of industrial scenarios where "personnel manage multiple devices," thereby improving the efficiency of unloading vehicle location confirmation.

[0063] Specifically, the unloading vehicle positioning confirmation method of the present invention can be implemented by programming a PLC program using Visual Studio.

[0064] In practical applications, first create a new Visual Studio project, select Forms application, name the project CapturePicture, use the .NET Framework 4.8 target framework, and set the output type to Windows application.

[0065] Furthermore, add ModbusTcpUil.cs and CHCNetSDK.cs to the CapturePicture project.

[0066] Furthermore, add the NuGet EasyModbus package to From1.cs in the CapturePicture project.

[0067] Furthermore, in the CapturePicture project, create two new "Label" controls on the new form in From1.cs, namely "Current Warehouse Number" and "label3", and create a new "pictureBox1" control to display the current video window.

[0068] See Figure 2 The diagram shown is a screenshot of the unloading truck positioning confirmation screen displayed in a video pop-up window. After the unloading truck is in place, 1 is the position of the unloading truck in the monitoring screen, 2 is the material drop point display window, 3 is the video pop-up window, 4 is the data of the current position of the unloading truck, and 5 is the alignment drop point number.

[0197] It should be noted that when the unloading vehicle reaches the preset arrival point, the PLC program sends a position pulse signal, which controls the upper control unit to pop up a video window showing the unloading vehicle's position. The program automatically reads the real-time position data of the unloading vehicle from the PLC register, writes the read position data into the "label3" control, and displays the current position on the video window. Simultaneously, an image acquisition signal is triggered to capture an image of the unloading vehicle's current position, and the captured image is displayed in the current "pictureBox1" control. A screenshot of the video window is taken and saved, named with the year, month, day, hour, minute, and second, and stored in a preset folder for easy tracking.

[0198] See Figure 3 The diagram illustrates the process for confirming the unloading vehicle's positioning. In practical applications, the desired warehouse number (i.e., the preset arrival point) can be selected via the control panel. The Schneider local station PLC can then forward the signal for the preset arrival point to the unloading vehicle's PLC, which receives the Schneider data containing the preset arrival point. After the unloading vehicle passes its self-check, the warehouse relocation program begins, and the vehicle starts moving. During the relocation process, an onboard scanner performs real-time scanning of the Gray busbar to obtain the current position data. The unloading vehicle's PLC compares this current position data with the preset arrival point. If the current position data matches the preset arrival point, the unloading vehicle stops moving. The unloading vehicle then sends its stopping position data from its PLC to the Schneider local station PLC, which receives the stopping position data. Simultaneously, the pop-up pulse signal of the unloading vehicle is activated. The pop-up pulse signal activates the video pop-up through the upper machine position screen. The video pop-up is displayed directly in front of the upper machine position, and a screenshot of the video pop-up is saved to the local folder.

[0199] The technical solution of this invention pre-calibrates the positions of each material drop point on the Gray busbar, determines the point-position mapping relationship, obtains the actual position of the unloading vehicle on the Gray busbar during its movement, and compares the actual position of the unloading vehicle with the preset arrival point position based on the point-position mapping relationship. When the actual position of the unloading vehicle and the preset arrival point position are the same, it indicates that the unloading vehicle has arrived. Automatic and real-time confirmation of the unloading vehicle's arrival is achieved by popping up a video window on the front-end page, thereby improving the efficiency and accuracy of unloading vehicle position confirmation in industrial scenarios.
