Technical Field

[0001] This invention relates to the field of material transportation technology, and in particular to a method, device, system, equipment and medium for monitoring transport vehicles. Background Technology

[0002] In the field of material transportation, the transportation status of transport vehicles is often monitored manually during the unloading of cargo from ships.

[0003] However, this monitoring method is insufficient to cover the entire transportation process, leading to violations such as changing license plates, repeated loading and unloading, or leaving the site without unloading. Therefore, how to monitor the transportation status of vehicles is a pressing technical problem that needs to be solved. Summary of the Invention

[0004] This application provides a method, device, system, equipment, and medium for monitoring transport vehicles, which solves the technical problem of difficulty in monitoring the transport status of transport vehicles in the prior art, and achieves the technical effect of monitoring the transport status of transport vehicles and reducing violations of transport vehicle operations.

[0005] Firstly, this application provides a method for monitoring transport vehicles, including:

[0006] After the transport vehicle enters the material yard through the access control, an entry record for this transport process is generated and the transport time of the transport vehicle in this transport process is monitored.

[0007] If the transport vehicle has entry records, overload records, and empty vehicle exit records from the previous transport process, a measurement application form for the current transport process is generated; the measurement application form indicates that the transport vehicle is qualified to perform the weighing task in the current transport process.

[0008] Once the transport vehicle has completed the weighing process, an overweight record for this transport is generated.

[0009] An alarm signal is generated if the transportation time exceeds the preset time and the weighing task is not performed;

[0010] When a transport vehicle arrives at the gate in the direction it is heading out of the material yard, the image recognition equipment is controlled to perform image recognition on the transport vehicle. If the image recognition result indicates that the vehicle is empty, the gate is controlled to open and an empty vehicle exit record for this transport process is generated.

[0011] Furthermore, when the transport vehicle arrives at the access control point in the direction it will enter the material yard, the method also includes:

[0012] The system controls the image recognition equipment to identify the license plate number of the transport vehicle, and controls the access control to open if the license plate number meets the registration requirements.

[0013] Furthermore, if the transport vehicles have transported all the materials from the unloading end to the material yard, the method also includes:

[0014] The total weight to be transported is determined based on the overweight records corresponding to each weighing task.

[0015] Obtain the total unloading weight at the unloading end. If the total transport weight exceeds the total unloading weight, generate an abnormal signal.

[0016] Furthermore, for each transportation process, the method also includes:

[0017] Establish a correlation between the license plate number, entry record, overload record, and empty vehicle exit record of the transport vehicle;

[0018] If there is a mismatch between the license plate number, entry record, overload record, and empty vehicle exit record during the process of establishing the association, an alarm signal will be generated.

[0019] Furthermore, when the image recognition result indicates a loaded vehicle, the method also includes:

[0020] Control the access control to remain closed and generate an alarm signal.

[0021] Furthermore, the preset time is 10 minutes.

[0022] Secondly, this application provides a transport vehicle monitoring device, comprising:

[0023] The entry record and time module is used to generate an entry record for the current transportation process and monitor the transportation time of the vehicle after it enters the material yard through the access control.

[0024] The metering application form generation module is used to generate a metering application form for the current transportation process when the transport vehicle has entry records, overload records, and empty vehicle exit records from the previous transportation process; the metering application form indicates that the transport vehicle is qualified to perform the weighing task in the current transportation process.

[0025] The overweight record generation module is used to generate an overweight record for the current transportation process after the transport vehicle has completed the weighing task.

[0026] The alarm signal generation module is used to generate an alarm signal when the transportation time exceeds the preset time and the weighing task is not performed;

[0027] The image recognition control module is used to control the image recognition equipment to perform image recognition on the transport vehicle when it arrives at the gate in the direction of leaving the material yard. If the image recognition result is that the vehicle is empty, the module controls the gate to open and generates an empty vehicle exit record for this transport process.

[0028] Thirdly, this application provides a transport vehicle monitoring system, including:

[0029] Access control is used to restrict transport vehicles from entering or leaving the material yard.

[0030] Image recognition equipment is installed at the access control point to perform image recognition on transport vehicles;

[0031] A controller for performing a transport vehicle monitoring method as provided in the first aspect.

[0032] Fourthly, this application provides an electronic device, comprising:

[0033] processor;

[0034] Memory used to store processor-executable instructions;

[0035] The processor is configured to execute a method for monitoring transport vehicles as provided in the first aspect.

[0036] Fifthly, this application provides a non-transitory computer-readable storage medium that, when the instructions in the storage medium are executed by the processor of an electronic device, enables the electronic device to perform a method for monitoring a transport vehicle as provided in the first aspect.

[0037] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0038] This application provides a method for monitoring transport vehicles, including: after a transport vehicle enters a material yard through an access control system, generating an entry record for the current transport process and monitoring the transport time of the current transport process; if the transport vehicle has an entry record, an overload record, and an empty vehicle exit record from the previous transport process, generating a metering application form for the current transport process; the metering application form indicates that the transport vehicle has the conditions to perform the weighing task in the current transport process; if the transport vehicle completes the weighing task, generating an overload record for the current transport process; if the transport time exceeds a preset time and the weighing task is not performed, generating an alarm signal; when the transport vehicle arrives at the access control system in the direction of leaving the material yard, controlling an image recognition device to perform image recognition on the transport vehicle, and if the image recognition result is an empty vehicle, controlling the access control system to open and generating an empty vehicle exit record for the current transport process.

[0039] As can be seen, this embodiment of the application, by linking access control records and metering records, can monitor the transportation status of transport vehicles in the material yard, thereby promptly detecting violations by transport vehicles. Vehicles are only allowed to perform new transportation tasks after completing a closed-loop process of "entry-weighing-unloading-exit." Simultaneously, weighing within a preset time after entry effectively reduces the possibility of transport vehicles changing license plates and repeatedly weighing themselves after entering the material yard, as well as violations such as improper loading and unloading. Furthermore, image recognition is used to prevent loaded vehicles from carrying pre-measured materials out of the material yard, reducing redundant weighing to a certain extent, optimizing the work process, and lowering the cost of manual supervision.

[0046] This application provides a method for monitoring transport vehicles, which solves the technical problem in the prior art that transport vehicles are prone to illegal operations in material yards.

[0047] The technical solution of this application embodiment is to solve the above-mentioned technical problems, and the general idea is as follows:

[0048] This application provides a method for monitoring transport vehicles, including: after a transport vehicle enters a material yard through an access control system, generating an entry record for the current transport process and monitoring the transport time of the current transport process; if the transport vehicle has an entry record, an overload record, and an empty vehicle exit record from the previous transport process, generating a metering application form for the current transport process; the metering application form indicates that the transport vehicle has the conditions to perform the weighing task in the current transport process; if the transport vehicle completes the weighing task, generating an overload record for the current transport process; if the transport time exceeds a preset time and the weighing task is not performed, generating an alarm signal; when the transport vehicle arrives at the access control system in the direction of leaving the material yard, controlling an image recognition device to perform image recognition on the transport vehicle, and if the image recognition result is an empty vehicle, controlling the access control system to open and generating an empty vehicle exit record for the current transport process.

[0049] As can be seen, this embodiment of the application, by linking access control records and metering records, can monitor the transportation status of transport vehicles in the material yard, thereby promptly detecting violations by transport vehicles. Vehicles are only allowed to perform new transportation tasks after completing a closed-loop process of "entry-weighing-unloading-exit." Simultaneously, weighing within a preset time after entry effectively reduces the possibility of transport vehicles changing license plates and repeatedly weighing themselves after entering the material yard, as well as violations such as improper loading and unloading. Furthermore, image recognition is used to prevent loaded vehicles from carrying pre-measured materials out of the material yard, reducing redundant weighing to a certain extent, optimizing the work process, and lowering the cost of manual supervision.

[0050] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0051] First, it should be clarified that the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0052] Shipping scrap steel is an important mode of transportation for port-adjacent steel companies, offering advantages such as large capacity and low cost. However, significant management loopholes exist in the process of transporting scrap steel by road. Traditional technical solutions rely on basic access control systems and manual video surveillance, which cannot effectively monitor the transportation status of vehicles. This leads to a high probability of violations, including duplicate weighing, vehicle identification tampering, and abnormal cargo loading conditions.

[0053] Existing access control systems can only perform simple identification and recording of vehicles entering and leaving the site. However, metering operations (such as weighing) are completely independent of access control management, allowing transport vehicles to engage in unauthorized operations within the material yard by changing license plates, repeatedly loading and unloading, or leaving without unloading. For example, after a vehicle enters the material yard, due to the lack of a mandatory correlation between entry time and weighing time, drivers can bypass supervision by delaying weighing or changing license plates midway, thus repeatedly weighing the same batch of materials.

[0054] In addition, camera systems that rely on manual monitoring cannot determine the cargo status of vehicles in real time. Fully loaded vehicles may illegally leave the material yard and then re-enter for weighing, resulting in false increases in material or data distortion.

[0055] To address the aforementioned problems, this application provides a method for monitoring transport vehicles.

[0056] First, this application will describe the transportation process of the transport vehicle. For example... Figure 1 The diagram shown is a schematic representation of the transportation process of a transport vehicle according to an embodiment of this application.

[0057] The transportation process utilizes a transportation vehicle monitoring system provided in this application embodiment. The system includes: access control 2, image recognition device 4, and controller (not shown in the figure).

[0058] After the transport vehicles complete loading of materials at the dock from the unloading end 6 (e.g., a material transport ship) for this material transfer task, the heavily loaded transport vehicle 101 enters the material yard through gate 2. Upon entering the material yard, the loaded materials are weighed using the weighbridge equipment 3 (weighing task), and then the vehicle proceeds to the storage station 5. After unloading the materials at the storage station 5, the unloaded transport vehicle 102 exits the material yard through gate 2. The transport vehicles repeat the above transportation process until the material transfer is completed.

[0059] Understandably, material handling refers to a systematic operational process in which transport vehicles transfer all designated materials from unloading end 6 to storage station 5 in the material yard through multiple transport processes. In other words, the transport vehicles transport all materials from unloading end 6 to the material yard. For each transport process, the transport vehicle needs to complete material loading, access control, weighing, material unloading, and empty vehicle departure in sequence.

[0060] Discharge end 6 refers to the initial unloading position of the material, and is usually equipped with metering equipment to record the total unloading weight. Taking ship-to-truck transport as an example, discharge end 6 is the material transport vessel, and the total unloading weight is determined by the weight change in the ship's draft.

[0061] Access control 2 includes a barrier gate mechanism, which is opened or closed via an electric lifting rod or fence.

[0062] An image recognition device 4 is installed at access control 2 to perform image recognition on transport vehicles. The image recognition device 4 includes various types of cameras (e.g., infrared or visible light) to identify the license plate number of the transport vehicle when it arrives at access control 2 in the direction of entering the material yard; and to identify the image information of the transport vehicle when it arrives at access control 2 in the direction of leaving the material yard.

[0063] Furthermore, the image recognition device 4 analyzes image information using visual algorithms to determine the transport vehicle's carrying status. The carrying status includes a heavily loaded state (hereinafter referred to as a loaded vehicle) with materials and an empty state (hereinafter referred to as an empty vehicle) without materials.

[0064] The weighbridge equipment 3 includes a weighing platform. When the transport vehicle is stationary on the weighing platform or when the transport vehicle passes the weighing platform at low speed, the weighing sensor collects the total weight and, after subtracting the preset tare weight (empty vehicle weight) of the transport vehicle, obtains the net weight information of the material corresponding to the current transportation process.

[0065] Having described the transportation process of the transport vehicle as above, this application embodiment will further describe a method for monitoring transport vehicles as follows.

[0066] like Figure 2 The diagram shown is a flowchart of a transportation vehicle monitoring method provided in an embodiment of this application, including steps S1-S5.

[0067] Step S1: After the transport vehicle enters the material yard through the access control 2, generate the entry record for this transport process and monitor the transport time of the transport vehicle in this transport process;

[0068] Step S2: If the transport vehicle has the entry record, overload record and empty vehicle exit record of the previous transport process, generate a measurement application form for the current transport process; the measurement application form indicates that the transport vehicle has the conditions to perform the weighing task in the current transport process.

[0069] Step S3: After the transport vehicle has completed the weighing task, generate an overweight record for this transport process.

[0070] Step S4: If the transportation time exceeds the preset time and the weighing task is not performed, an alarm signal is generated;

[0071] Step S5: When the transport vehicle arrives at the gate 2 in the direction of leaving the material yard, control the image recognition device 4 to perform image recognition on the transport vehicle. If the image recognition result is that the vehicle is empty, control the gate 2 to open and generate an empty vehicle exit record for this transport process.

[0072] Regarding step S1, after the transport vehicle enters the material yard through gate 2, an entry record for this transport process is generated and the transport time of the transport vehicle in performing this transport process is monitored.

[0073] It should be noted that the starting point for monitoring transportation time is the moment when the transport vehicle enters the material yard through gate 2 and an entry record is generated.

[0074] Before the transport vehicle passes through gate 2, that is, when the transfer vehicle arrives at gate 2 in the direction of entering the material yard, the image recognition device 4 is controlled to identify the license plate number of the transport vehicle. If the license plate number meets the registration conditions, the gate 2 is controlled to open.

[0075] The registration requirements refer to the pre-registration and approval of the vehicle license plate number in the system database, so that the transport vehicle has the legal and compliant access qualification to enter the material yard.

[0076] Regarding step S2, if the transport vehicle has the entry record, overload record, and empty vehicle exit record of the previous transport process, a measurement application form for the current transport process is generated; the measurement application form indicates that the transport vehicle has the conditions to perform the weighing task in the current transport process.

[0077] A measurement request form is a task authorization certificate used to authorize transport vehicles to perform weighing tasks during this transportation process.

[0078] An alarm signal is generated if the transport vehicle lacks at least one of the following records from the previous transport process: entry record, overload record, or empty vehicle exit record. The vehicle's license plate number is used as an identifier to link the previous transport process with the current transport process, thereby determining whether the transport vehicle has the entry record, overload record, or empty vehicle exit record from the previous transport process.

[0079] Furthermore, for each transportation process, the method also includes steps S21-S22.

[0080] Step S21: Establish the association between the vehicle license plate number, entry record, overload record, and empty vehicle exit record of the transport vehicle;

[0081] In step S22, if there is a mismatch between the license plate number, entry record, overload record, and empty vehicle exit record during the process of establishing the association, an alarm signal is generated.

[0082] Regarding step S21, the association is used to ensure that the entry record, overweight record, and empty vehicle exit record of each transportation process form a closed loop, thereby reducing abnormal operations of transport vehicles in the material yard (such as repeated weighing before leaving the factory). Furthermore, in the event of a measurement dispute, all transportation records and related data corresponding to a specific license plate number can be quickly traced.

[0083] Regarding step S22, the mismatch between license plate number, entry record, overweight record, and empty vehicle exit record includes at least one of the following: inconsistent license plate number (the license plate number in the entry record is inconsistent with the license plate number in the overweight record), time contradiction (the current entry time is before the previous exit time, suspected of being a duplicate entry), and duplicate weighing (the same license plate number has multiple weighing records at the same time).

[0084] Regarding step S3, after the transport vehicle has completed the weighing task, an overweight record for this transport process is generated.

[0085] For example, the weighing task includes: vehicle positioning (detecting that the transport vehicle has fully entered the weighing platform), weight acquisition (the weighing sensor acquires the total weight), net weight calculation (net weight = total weight - tare weight), and data binding (associating the net weight with the license plate number and the entry record of this transport process).

[0086] It is understandable that gross weight refers to the weight of the transport vehicle under heavy load during this transportation process, net weight refers to the weight of the materials carried by the transport vehicle during this transportation process, and tare weight refers to the weight of the transport vehicle under empty load.

[0087] Regarding step S4, if the transportation time exceeds the preset time and the weighing task is not performed, an alarm signal is generated.

[0088] The preset time is based on the normal travel time of the transport vehicle from gate 2 to the weighing platform, in order to reduce the need for transport vehicles to change license plates and then be weighed after entering the material yard. For example, the preset time is 10 minutes.

[0089] The alarm signal is used to prompt production personnel to check the transportation status of relevant transport vehicles. Before the check result is normal, the relevant transport vehicles are not allowed to perform any task procedures (such as weighing, leaving the material yard, or unloading materials).

[0090] Regarding step S5, when the transport vehicle arrives at gate 2 in the direction of leaving the material yard, the image recognition device 4 is controlled to perform image recognition on the transport vehicle. If the image recognition result is that the vehicle is empty, gate 2 is controlled to open and an empty vehicle exit record for this transport process is generated.

[0091] Furthermore, if the image recognition result indicates a loaded vehicle, the control access 2 remains closed and an alarm signal is generated.

[0092] For example, after the image recognition device 4 performs image recognition, if the obtained image features include a clearly visible carriage floor and only a small volume of material covering the carriage (e.g., volume percentage < 5%), the output recognition result is "empty carriage". If the obtained image features include a large area covered by material in the carriage (e.g., volume percentage > 50%), the output recognition result is "loaded carriage".

[0093] Furthermore, when the transport vehicles have transported all the materials from the unloading end to the material yard, that is, when the transport vehicles have completed the material transfer, the method also includes steps S61-S62.

[0094] Step S61: Determine the total weight to be transported based on the overweight records corresponding to each weighing task.

[0095] Step S62: Obtain the total unloading weight of unloading end 6. If the total transport weight exceeds the total unloading weight, generate an abnormal signal.

[0096] Regarding steps S61-S62, the total transport weight refers to the cumulative value of the material's net weight information in all overweight records corresponding to the transportation process. Abnormal signals are used to prompt production personnel to verify weight information and trace potential causes of abnormalities during transportation (such as multiple weighings of the same vehicle with the same license plate within a short period).

[0097] For example, after implementing a vehicle monitoring method provided in this application, a company optimized the access control and unloading supervision positions, reducing monthly labor costs by 8,000 (salaries) × 8 (number of people) = 64,000.

[0098] In summary, this application provides a method for monitoring transport vehicles, including: after a transport vehicle enters the material yard through access control 2, generating an entry record for the current transport process and monitoring the transport time of the current transport process; if the transport vehicle has an entry record, an overload record, and an empty vehicle exit record from the previous transport process, generating a metering application form for the current transport process; the metering application form indicates that the transport vehicle has the conditions to perform the weighing task in the current transport process; if the transport vehicle completes the weighing task, generating an overload record for the current transport process; if the transport time exceeds a preset time and the weighing task is not performed, generating an alarm signal; when the transport vehicle arrives at access control 2 in the direction of leaving the material yard, controlling the image recognition device 4 to perform image recognition on the transport vehicle, and if the image recognition result is an empty vehicle, controlling access control 2 to open and generating an empty vehicle exit record for the current transport process.

[0099] As can be seen, this embodiment of the application, by associating access control 2 records with metering records, can monitor the transportation status of transport vehicles in the material yard, thereby promptly detecting violations by transport vehicles. Vehicles are only allowed to perform new transportation tasks after completing the entire closed-loop process of "entry-weighing-unloading-exit." Simultaneously, weighing is required within a preset time after entry, effectively reducing the possibility of transport vehicles changing license plates and repeatedly weighing themselves after entering the material yard, as well as violations such as improper loading and unloading. Furthermore, image recognition is used to prevent loaded vehicles from carrying pre-measured materials out of the material yard, reducing redundant weighing to a certain extent, optimizing the work process, and lowering the cost of manual supervision.

[0103] The overweight record generation module 33 is used to generate an overweight record for the current transportation process when the transport vehicle has completed the weighing task.

[0104] The alarm signal generation module 34 is used to generate an alarm signal when the transportation time exceeds the preset time and the weighing task is not performed;

[0105] The image recognition control module 35 is used to control the image recognition device to perform image recognition on the transport vehicle when the transport vehicle arrives at the gate in the direction of leaving the material yard. If the image recognition result is that the vehicle is empty, the module controls the gate to open and generates an empty vehicle exit record for this transport process.

[0106] Furthermore, the device also includes an access control module for:

[0107] When a transport vehicle arrives at the access control point in the direction it is heading into the material yard, the image recognition equipment is controlled to identify the vehicle's license plate number. If the license plate number meets the registration requirements, the access control point is opened.

[0108] Furthermore, the device also includes an abnormal signal generation module for:

[0109] The total weight to be transported is determined based on the overweight records corresponding to each weighing task.

[0114] Furthermore, the access control module is also used for:
