Description

Technical Field

[0001] This application relates to the field of truck scale technology, specifically to a truck scale weighing system, method, equipment, and medium. Background Technology

[0002] In the logistics and transportation processes of large enterprises such as steel mills, truck scales are key equipment for vehicle weighing. Currently, some steel mills have multiple truck scales for weighing incoming gross weight and outgoing tare weight, with a total of more than ten truck scales deployed within the mill. These truck scales have basically achieved automatic weighing and remote centralized control, meaning that weighing tasks are automatically assigned by a remote centralized weighing hall, and weighing personnel are mainly responsible for video monitoring of the weighing process and handling abnormal situations.

[0003] During the vehicle weighing process at the factory, safety and metrology regulations require all personnel to disembark and not remain in the weighing area. Current technology primarily relies on weighing personnel manually monitoring via remote video feeds. However, since a single weighing personnel often needs to monitor multiple truck scales and other weighing equipment simultaneously, the monitoring workload is heavy, and it's difficult to maintain focus for extended periods. This results in the inability to effectively monitor 100% of unauthorized personnel (such as remaining in the driver's cab or on the weighing platform), leading to a risk of missed detections.

[0004] Secondly, some transport vehicles carry water tanks, and weighing rules require that the water in the tanks be emptied to prevent weight fraud. Since on-site operators have been removed from the truck scales, and remote monitoring is used, it is impossible to physically contact or closely observe the status of the water tanks, making it difficult to effectively verify whether the water tanks are truly empty. Summary of the Invention

[0005] In view of this, this application provides a truck scale weighing system, method, equipment, and medium. The main purpose is to solve the technical problems of the current truck weighing process at the factory, which mainly relies on weighing personnel to manually monitor the process through remote video screens. Since a weighing personnel often needs to monitor multiple truck scales and other weighing equipment at the same time, the monitoring task is heavy and it is difficult to concentrate for a long time. This makes it impossible to effectively monitor the on-duty status of vehicle weighing personnel without 100% compliance, resulting in the risk of missed detection. In addition, the remote monitoring method cannot physically contact or observe the water tank status at close range, making it difficult to effectively verify whether the water tank is actually emptied.

[0006] In a first aspect, this application provides a truck scale weighing system, characterized in that it includes an intelligent weighing system, an image analysis module, a voice broadcast module, a large on-site screen, a front-end camera, a rear-end camera, a driver's cab camera, and personnel and water flow cameras set around the weighing platform. The image analysis module is used to perform real-time image analysis on the target images captured by the front camera, the rear camera, and the driver's cab camera to determine the personnel identification results; The intelligent weighing system is used to identify the vehicle's license plate number when the vehicle is put on the scale, and to retrieve the vehicle's relevant information based on the license plate number, including whether the vehicle is carrying a water tank. The intelligent weighing system is also used to control the voice broadcast module and the large screen on site to guide the driver to verify the status of the water tank valve when the vehicle is carrying the water tank. If the water tank valve is in the open state, and there is no water flowing out of the water tank valve outlet as captured by the personnel and water flow camera, and the personnel judgment result is that there are no personnel staying in the front, rear and driver's cab of the vehicle, the intelligent weighing system will automatically weigh the vehicle.

[0007] Secondly, this application provides a weighing method for truck scales, including: Real-time image analysis is performed on target images captured by the front camera, rear camera, and driver's cab camera to determine the personnel identification results. When a vehicle is placed on a weighbridge, the vehicle's license plate number is identified, and the vehicle's relevant information is retrieved based on the license plate number. The relevant vehicle information includes whether the vehicle is carrying a water tank. When the vehicle is carrying the water tank, the voice broadcast module and the large on-site screen guide the driver to verify the status of the water tank valve. If the water tank valve is in the open state, and there is no water flowing out of the monitored water tank valve outlet, and the personnel identification result indicates that there are no personnel remaining in the front, rear, and driver's cab of the vehicle, then the vehicle will be automatically weighed.

[0008] Thirdly, this application provides an electronic device including a storage medium, a processor, and a computer program stored on the storage medium and executable on the processor, wherein the processor executes the computer program to implement the truck scale weighing method described in the second aspect.

[0009] Fourthly, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the truck scale weighing method described in the second aspect.

[0010] By employing the above technical solutions, this application provides a truck scale weighing system, method, equipment, and medium. Compared with existing technologies, this application can use an image analysis module to perform real-time image analysis on target images captured by the front camera, rear camera, and cab camera to determine the personnel identification results. The intelligent weighing system is used to identify the vehicle's license plate number when the vehicle is put on the scale and to call up relevant vehicle information based on the license plate number, including whether it carries a water tank. When the vehicle carries a water tank, the intelligent weighing system also controls the voice broadcast module and the on-site large screen to guide the driver to verify the water tank valve status. If the water tank valve is open, and there is no water flowing out of the water tank valve outlet as captured by the monitored personnel and the water flow camera, and the personnel identification result indicates that there are no personnel remaining at the front, rear, or cab of the vehicle, the intelligent weighing system automatically weighs the vehicle.

[0011] This application's solution incorporates three cameras: one at the front of the vehicle, one at the rear, and one in the driver's cab. An image analysis module performs real-time image analysis on the target images captured by these cameras, automatically determining the presence of personnel (i.e., automatically identifying whether anyone is lingering at the front, rear, or in the driver's cab). This automated personnel identification technology replaces traditional manual remote video monitoring. The system works tirelessly and can simultaneously cover multiple monitoring points, thus avoiding the risk of missed detections due to the heavy workload and lack of focus of manual monitoring. This achieves 100% effective monitoring of a large number of personnel violating regulations while on duty.

[0012] This application utilizes an intelligent weighing system to identify whether a vehicle carries a water tank. When a water tank is present, the system automatically guides the driver to verify the status of the water tank valve. The system not only monitors whether the valve is open but also uses cameras to specifically capture images of the water tank valve outlet. Only when no water flow is detected (physical proof that the water has been drained) is the condition deemed met. This method, through remote visual guidance combined with specific water flow status detection, overcomes the shortcomings of existing remote monitoring systems that lack physical contact or close-range observation, achieving effective verification of whether the water tank is truly empty.

[0013] The above description is only an overview of the technical solution of this application.

[0020] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] To address the current issue that the weighing process for vehicles entering the factory relies primarily on manual monitoring by weighing personnel via remote video feeds, which is problematic because a single weighing personnel often needs to monitor multiple truck scales and other weighing equipment simultaneously, resulting in a heavy workload, difficulty in maintaining focus for extended periods, and an inability to effectively monitor personnel violations, leading to missed detections. Furthermore, remote monitoring cannot physically access or closely observe the water tank's status, making it difficult to effectively verify whether the tank is truly empty. This application provides a truck scale weighing system.

[0022] like Figure 1 As shown, an embodiment of this application provides a truck scale weighing system, including: an intelligent weighing system, an image analysis module, a voice broadcast module, a large on-site screen, front-facing cameras, rear-facing cameras, a driver's cab camera, personnel and water flow cameras positioned around the weighing platform, verification color bars, micro-motion detection switches positioned around the weighing platform for placing the verification color bars, and a scale valve camera. The image analysis module includes an AI model analysis unit and an AI scale model, and also includes a personnel identification module.

[0023] When a vehicle drives onto the weighbridge platform, the intelligent weighing system starts working. It can identify the vehicle's license plate number using a vehicle number recognition device (such as a license plate recognition camera, not shown in the figure). Based on the identified license plate number, the intelligent weighing system retrieves relevant vehicle information from the vehicle information database. This information includes, but is not limited to, the name of the material being weighed, the supplier, the vehicle model, historical tare weight, and whether it carries a water tank.

[0024] The intelligent weighing system verifies the weighing conditions of vehicles according to preset rules. When other conditions for vehicle weighing (such as the vehicle being fully on the scale and the weighing instrument reading being stable) are met, the system uses the personnel identification results from the image analysis module and the water tank valve verification results as the final confirmation conditions before weighing. Only when the water tank valve status verification is passed (if the vehicle has a water tank), and the personnel identification results show that there are no personnel remaining on the scale platform or in the driver's cab, will the intelligent weighing system automatically weigh the vehicle.

[0025] For vehicles carrying water tanks, the system has a strict water tank emptying verification process, the specific steps of which are as follows: After the vehicle is guided onto the weighing platform and parked, the personnel disembark. The intelligent weighing system can determine whether the vehicle is carrying a water tank based on the vehicle's relevant information. If the vehicle is carrying a water tank, the intelligent weighing system can control the voice broadcast module to issue a voice prompt such as "Please open the water tank valve and use the color bar for verification." Simultaneously, it can control the large screen to demonstrate how to use the verification color bar and open the water tank valve, guiding the driver on the operation. The verification color bar is a thin steel rod painted red at one end and silver at the other, placed near the driver's exit from the vehicle on the vicinity of the weighing platform.

[0026] When the driver removes the verification color bar, the micro-motion detection switch detects its removal and triggers the personnel and water flow cameras to start recording video near the water tank. At this time, the intelligent weighing system can again prompt the driver to open the water tank valve via the voice broadcast module, such as "Please open the water tank valve".

[0027] Video footage from personnel and water flow cameras at the water tank valve outlet is transmitted to the AI ​​model analysis unit of the image analysis module. The AI ​​model analysis unit analyzes the video in real time to determine if the water tank valve is open and if there is no water flow from the outlet. If the water tank valve is open and there is no water flow, the intelligent weighing system can control the voice broadcast module and the large on-site screen to guide the driver to fully insert the silver end of the verification bar into the water tank valve. A voice prompt will say something like, "Please fully insert the silver end of the verification bar into the water tank valve," and the large on-site screen will simultaneously display the corresponding operation.

[0028] To prevent incomplete drainage due to the driver not fully opening the valve or only partially opening it, the scale valve camera begins capturing images of the scale at the water tank valve (i.e., the image after the color bar is inserted into the valve) after the driver follows the instructions. This image is then transmitted to the AI ​​scale model in the image analysis module. The AI ​​scale model uses the captured image to determine whether the verification color bar penetrates the center diameter of the water tank valve. If the verification color bar does penetrate the center diameter, it proves that the valve is fully open and the passage is clear, ensuring complete drainage of the water tank. At this point, the intelligent weighing system controls the voice broadcast module and the large on-site screen to guide the driver to return the verification color bar to its original position. The voice prompt will say something like "Please return the color bar to its original position," and the large on-site screen will display a demonstration of the color bar being returned to its original position.

[0029] When the microswitch detects the color bar returning to its original position, the intelligent weighing system's voice broadcast module can prompt the driver to press the weighing confirmation button, such as "Please press the weighing confirmation button." At the same time, the large screen on site will display a schematic image of the weighing confirmation button.

[0030] The front-facing camera, rear-facing camera, and cab-mounted camera continuously capture images of the area surrounding the weighbridge. The image analysis module uses the top-left pixel of the image as the origin, the horizontal direction of the image as the x-axis, and the vertical direction of the vehicle as the y-axis. It extracts and stores the pixel set {Xt, Yt} of the weighbridge border area captured by the front-facing camera, {Xw, Yw} of the weighbridge border area captured by the rear-facing camera, and {Xj, Yj} of the weighbridge border area captured by the cab-mounted camera.

[0031] When the driver presses the weighing confirmation button, the image analysis module uses an AI human body recognition model to perform real-time image analysis on the target images captured by the front camera, rear camera, and driver's cab camera. If a human body is present, a set of pixel coordinates for the human body image is generated, which may include the pixel coordinates for the front human body image {Xtt, Ytt}, the rear human body image {Xww, Yww}, and the driver's cab human body image {Xjj, Yjj}. The personnel identification module compares the set of pixel coordinates for the human body image generated by the AI ​​human body recognition model with the pre-stored pixel coordinates for the weighing platform border area.

[0032] If the pixel set {Xt, Yt} within the frame area of ​​the weighing platform captured by the camera at the front of the vehicle contains all or part of the pixel coordinate set {Xtt, Ytt} of the human image at the front of the vehicle, it indicates that the human body is located within the weighing platform area at the front of the vehicle, and the personnel identification module determines that there is a person at the front of the vehicle. If the pixel set {Xw, Yw} within the frame area of ​​the weighing platform captured by the rear camera contains all or part of the pixel coordinate set {Xww, Yww} of the human image at the rear of the vehicle, it indicates that the human body is located within the weighing platform area at the rear of the vehicle, and the person identification result is that there is someone at the rear of the vehicle. If the set of pixels {Xj, Yj} within the frame area of ​​the weighing platform captured by the camera in the cab contains all or part of the set of pixel coordinates {Xjj, Yjj} of the human image in the cab, it indicates that the human body is located in the cab, and the personnel identification result is that there is someone in the cab. If none of the above sets contain the corresponding pixel array, or if the AI ​​human body recognition model fails to recognize a human body, then an "unmanned" judgment will be given, meaning that there are no people staying at the front, rear, or driver's cab of the vehicle.

[0033] When the system receives the weighing confirmation button switch signal, the weighing system confirms the weighing conditions. The confirmation conditions may include the weighing system being in a stable state (judged by the signal stability of the weighing sensor), no alarm for vehicle edge pressing detection (detected by the edge pressing sensor to check if the vehicle is pressing the edge), no personnel remaining on the weighing platform and in the driver's cab (the personnel identification module results in no one being present), and if there is a water tank, the water tank valve status verification is passed (valve open, no water flow, scale through).

[0034] If the personnel detection module determines that there is someone in the front, rear, or driver's cab of the vehicle, the intelligent weighing system will determine that the automatic weighing conditions are not met. In this case, the system can prompt the personnel to leave the weighing area and press the weighing confirmation button again through the voice broadcast module and the large screen on site, such as "There is someone in the front / rear / driver's cab. Please leave the weighing area and press the weighing confirmation button again."

[0035] When all weighing conditions are met, the intelligent weighing system automatically weighs the vehicle. After weighing is completed, subsequent processes are executed, such as printing weighing slips and storing data.

[0036] Through the above implementation methods, this application achieves physical-level verification of water tank emptying and automated and accurate identification of personnel lingering in the weighing area, effectively preventing human cheating and monitoring oversights, and greatly improving the accuracy and fairness of weighing.

[0037] like Figure 2 As shown, an embodiment of this application provides a truck scale weighing method, which can be applied to the above-mentioned truck scale weighing system. The truck scale weighing method may include: Step 101: Perform real-time image analysis on the target images captured by the front camera, rear camera, and driver's cab camera to determine the personnel identification results.

[0038] In this embodiment, the pixel at the top left corner of the image is taken as the origin, the horizontal direction of the image is the x-axis, and the vertical direction of the vehicle is the y-axis. The pixel array within the weighing platform border area captured by the front camera is represented by the set {Xt, Yt}, the pixel array within the weighing platform border area captured by the rear camera is represented by {Xw, Yw}, and the pixel array within the weighing platform border area captured by the cab camera is represented by {Xj, Yj}.

[0039] After the vehicle stops on the weighing platform, cameras at the front, rear, and driver's cab capture images of the front, rear, and driver's cab, respectively. An AI human recognition model analyzes these images. If a human figure is present, it generates the coordinate information of the human figure's pixel matrix, specifically the set for the front of the vehicle {Xtt, Ytt}, the set for the rear of the vehicle {Xww, Yww}, and the set for the driver's cab {Xjj, Yjj}.

[0040] The personnel identification module compares two sets of pixel data provided by the AI ​​human body analysis and image analysis modules. Specifically, the comparison is as follows: if {Xt, Yt} contains some pixels from {Xtt, Ytt}, the module determines that someone is in the front of the vehicle; if {Xw, Yw} contains some pixels from {Xww, Yww}, the module determines that someone is in the rear of the vehicle; if {Xj, Yj} contains some pixels from {Xjj, Yjj}, ​​the module determines that someone is in the driver's cab; if no human figure is found, the module determines that no one is present. Through this real-time image analysis process, the final personnel identification result is determined.

[0041] Step 102: When the vehicle is on the weighbridge, identify the vehicle's license plate number and retrieve the vehicle's relevant information based on the license plate number, including whether it is carrying a water tank.

[0042] When a vehicle is weighed on a weighbridge, the intelligent weighing system uses image recognition technology to identify the vehicle's license plate number. Based on the identified number, the system retrieves relevant vehicle information, including but not limited to the name of the goods being weighed, the supplier, the vehicle model, historical tare weight, and whether it has a water tank. For example, the system database pre-stores a mapping relationship between vehicle license plates and corresponding vehicle information. By querying this mapping relationship, the relevant information for the current vehicle can be quickly obtained. If the query result indicates that the vehicle carries a water tank, the subsequent processing will follow the water tank verification procedure; if it does not carry a water tank, the water tank verification steps will be skipped, and other weighing conditions will be directly confirmed.

[0043] Step 103: When the vehicle is carrying a water tank, control the voice broadcast module and the large screen on site to guide the driver to verify the status of the water tank valve.

[0044] Once it's confirmed that the vehicle carries a water tank, the voice broadcast module activates, announcing, "Driver, please open the water tank valve and verify with the color bar." Simultaneously, a large screen displays the verification process. The verification color bar, a thin steel rod painted red at one end and bright silver at the other, is placed near the weighing platform where the driver exits the vehicle. After the driver removes the color bar, a micro-motion detection switch triggers personnel and a water flow camera to record video of the area around the water tank for further analysis of the valve status and water flow.

[0045] Step 104: If the water tank valve is in the open state, and there is no water flowing out of the monitored water tank valve outlet, and the personnel judgment result is that there are no personnel remaining in the front, rear and driver's cab of the vehicle, then the automatic weighing of the vehicle shall be performed.

[0046] The AI ​​model analyzes and judges the personnel and water flow video. When the model determines that the valve has been opened and there is no water flowing out of the valve outlet, the system announces in voice, "Please insert the silver end of the color bar completely into the valve," and the large screen on site simultaneously displays a verification diagram. Next, the scale valve camera begins to capture images of the scale at the valve, and the AI ​​scale model analyzes and judges whether the scale truly penetrates the center diameter of the valve. When the AI ​​scale model analyzes that the scale truly penetrates the center diameter of the valve, the system announces in voice, "Please put the color bar back in its original position," and the large screen on site simultaneously displays a diagram of the color bar returning to its original position. When the microswitch detects that the color bar has returned to its original position, it indicates that the water tank valve status verification is complete and meets the requirements.

[0047] During the vehicle weighing process, when the system receives the weighing confirmation button switch signal, the weighing system confirms the weighing conditions, including the condition that no personnel are remaining on the weighing platform or in the driver's cab. Based on the personnel identification result obtained in step 101, if the personnel identification module identifies that there are people at the front, rear, or in the driver's cab, the system automatically determines that the weighing conditions are not met, and the system will announce in voice, "Please leave the weighing area and press the weighing confirmation button again."

[0048] When the water tank valve status verification is passed (valve open and no water flows out of the outlet, scale passes through the valve center diameter, color bar returns to its original position), and the personnel judgment result shows that there are no people remaining in the front, rear and cab of the vehicle, and the weighing system is in a stable state, and there are no alarms for vehicle edge detection, etc., the system will automatically perform the weighing operation on the vehicle. After the weighing is completed, the subsequent process will be executed, such as recording the weighing data and generating a weighing report.

[0049] Based on the above, Figure 2 Accordingly, this embodiment also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the above-described method. Figure 2 The method shown.

[0050] Based on this understanding, the technical solution of this application can be embodied in the form of a software product, which can be stored in a non-volatile storage medium (such as CD-ROM, USB flash drive, mobile hard drive, etc.) and includes several instructions to cause a computer device (such as personal computer, server, or network device, etc.) to execute the methods of various implementation scenarios of this application.

[0051] Based on the above, Figure 2 To achieve the above objectives, embodiments of this application also provide an electronic device, which includes a storage medium and a processor; the storage medium is used to store a computer program; the processor is used to execute the computer program to implement the above-described... Figure 2 The method shown.

[0052] Optionally, the aforementioned physical devices may also include a user interface, a network interface, a camera, radio frequency (RF) circuitry, sensors, audio circuitry, a Wi-Fi module, etc. The user interface may include a display screen, input units such as a keyboard, etc., and optional user interfaces may also include USB interfaces, card reader interfaces, etc. The network interface may optionally include standard wired interfaces, wireless interfaces (such as Wi-Fi interfaces), etc.

[0053] Those skilled in the art will understand that the physical device structure provided in this embodiment does not constitute a limitation on the physical device, and may include more or fewer components, or combine certain components, or have different component arrangements.

[0054] The storage medium may also include an operating system and a network communication module. The operating system is a program that manages the hardware and software resources of the aforementioned physical device, supporting the operation of the truck scale weighing program and other software and / or programs. The network communication module is used to enable communication between the various components within the storage medium, as well as communication with other hardware and software within the truck scale weighing physical device.

[0055] Through the above description of the embodiments, those skilled in the art can clearly understand that this application can be implemented by means of software plus necessary general-purpose hardware platform, or it can be implemented by hardware. By applying the solution of this embodiment, compared with the existing technology, this application can use the image analysis module to perform real-time image analysis on the target images captured by the front camera, rear camera, and cab camera to determine the personnel identification result; the intelligent weighing system is used to identify the vehicle's license plate number information when the vehicle is put on the scale, and call the vehicle's relevant information according to the license plate number information, including whether it carries a water tank; the intelligent weighing system is also used to control the voice broadcast module and the on-site large screen to guide the driver to verify the water tank valve status when the vehicle carries a water tank. If the water tank valve is in the open state, and there is no water flowing out of the water tank valve outlet captured by the monitored personnel and the water flow camera, and the personnel identification result is that there are no personnel staying in the front, rear, and cab of the vehicle, the intelligent weighing system will automatically weigh the vehicle.

[0056] This application's solution incorporates three cameras: one at the front of the vehicle, one at the rear, and one in the driver's cab. An image analysis module performs real-time image analysis on the target images captured by these cameras, automatically determining the presence of personnel (i.e., automatically identifying whether anyone is lingering at the front, rear, or in the driver's cab). This automated personnel identification technology replaces traditional manual remote video monitoring. The system works tirelessly and can simultaneously cover multiple monitoring points, thus avoiding the risk of missed detections due to the heavy workload and lack of focus of manual monitoring. This achieves 100% effective monitoring of a large number of personnel violating regulations while on duty.

[0057] This application utilizes an intelligent weighing system to identify whether a vehicle carries a water tank. When a water tank is present, the system automatically guides the driver to verify the status of the water tank valve. The system not only monitors whether the valve is open but also uses cameras to specifically capture images of the water tank valve outlet. Only when no water flow is detected (physical proof that the water has been drained) is the condition deemed met. This method, through remote visual guidance combined with specific water flow status detection, overcomes the shortcomings of existing remote monitoring systems that lack physical contact or close-range observation, achieving effective verification of whether the water tank is truly empty.
