[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] As introduced in the background technology, in the prior art, a universal truck scale is used to measure the tare weight and gross weight to calculate the net weight of the coal actually transported by the truck. However, this method cannot complete loading and unloading and weighing at the same time and place, resulting in the possibility that the truck driver may cheat by stealing or replacing coal. In order to solve the problem that coal truck drivers may cheat in the prior art, the embodiments of the present application provide a coal transportation anti-cheating system, a control method for a coal transportation anti-cheating system, a control device for a coal transportation anti-cheating system, a computer-readable storage medium, and a computer program product.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] The present application provides a coal transportation anti-cheating system 10, such as Figure 1 As shown, including:

[0030] An electronic truck scale 11 is used to weigh the vehicle to obtain the weight of the vehicle;

[0031] Specifically, electronic vehicle scales are commonly known as floor scales. They are mainly used for weighing bulk goods. They are mainly composed of load carriers, weighing display instruments, weighing sensors, connectors, limit devices, junction boxes and other components. When an empty or loaded vehicle drives onto the load carrier surface, under the action of gravity, one or more groups of weighing sensors under the load carrier surface will transmit the weighing values ​​to the weighing display instrument for display. The weighing display instrument is also connected to the control device to transmit the weighing value results.

[0032] A laser scanner 12, used for scanning the vehicle to obtain the volume of the vehicle;

[0033] Specifically, the laser scanner should include a laser radar and a pan-tilt, which can be a laser radar bucket loading (empty / loaded) scanning device with a pan-tilt, mainly used to scan and obtain the basic dimensions of the length, width and height of the bucket of the hauling vehicle, as well as the actual volume of the bucket when empty or loaded. In order to ensure that the buckets of hauling vehicles with different lengths, widths and heights can be fully covered and scanned, the laser radar device has a pan-tilt rotation function. When the laser radar is in operation, it is linked with the pan-tilt and rotates to complete the scanning of the entire area of ​​the bucket. The device is connected to the control device, which issues instructions for control, and finally obtains the scanned volume results.

[0034] Furthermore, the accuracy of the laser scanner selection, due to the large number of imported and domestic laser radar equipment, needs to ensure that the error range of the selected equipment is within a reasonable range, and that the error rate between the cumulative average calculated bulk density ratio of different types of coal and the actual is low. Whether the installation height of the laser radar and the rotation angle of the pan-tilt can fully cover the scanning of the entire truck bed range, because coal-hauling vehicles have different lengths, it is necessary to ensure that the laser radar combined with the pan-tilt scanning method can cover the entire truck bed range.

[0035] The control device 13 is respectively connected to the electronic vehicle scale and the laser scanner for communication. The control device is used to determine the bulk density ratio according to the scanned weight and volume, and to determine cheating when the difference between the bulk density ratio and the preset bulk density ratio is less than the preset difference.

[0036] Specifically, the control device is mainly used for a high-end general-purpose microcomputer with a friendly human-machine interface and a high-efficiency working platform for specific application fields. The device is mainly used to carry the basic hardware operating environment of the control method of the coal transportation anti-cheating system. The control device receives data from the electronic truck scale and laser scanner, calculates the vehicle's volume-to-weight ratio, and compares it with the preset volume-to-weight ratio to determine whether there is cheating. The control device has a built-in high-performance processor and data processing algorithm, which can calculate the volume-to-weight ratio in real time, compare it with the preset value, and generate a cheating judgment result.

[0037] In the above system, a laser scanner is newly added to the existing vehicle weighing system, so that not only the weight of the vehicle can be determined by the electronic truck scale, but also the volume of the vehicle can be scanned by the laser scanner. The bulk density ratio can be calculated by these two parameters. The bulk density ratio will be preset for each vehicle when it is transported. If the driver cheats by stealing coal, changing coal, or injecting water, the actual measured bulk density ratio will be different from the pre-configured bulk density ratio, and the driver can be determined to have cheated. This solves the problem that coal transport drivers in the prior art may cheat.

[0038] Specifically, the solution of the present application can effectively identify the real type of coal transported by the transport vehicle, thereby curbing and eliminating the cheating behavior of the transport driver to steal or replace coal, and ensuring the asset safety of the coal seller.

[0039] Common cheating behaviors include:

[0040] The actual transported weight is greater than the settled weight after weighing, for example: adding water (heavy objects) to the vehicle before weighing an empty vehicle, or secretly draining water (unloading heavy objects) before weighing a heavy vehicle; other objects are involved in the weighing (pressing the weight) when the empty vehicle is weighed; external force causes the weighing sensor to reduce the weight (prying the weight) when the heavy vehicle is weighed; other means make it impossible for the vehicle scale to accurately weigh.

[0041] The act of secretly replacing the type of coal, for example: Car A is used to transport low-priced coal, and Car B is used to transport high-priced coal. After Car A is weighed with its empty car, it exchanges license plates with Car B which has completed loading coal. Car B is weighed with its loaded car and the weight is settled based on the lower-priced coal. Car A abandons loading and leaves the site with its empty car weighed. The transport driver colludes with the weighhouse operator or coal loader to load the car with good quality coal as inferior quality coal (first load the expensive coal and then cover the top with cheap coal).

[0042] The act of changing vehicle license plates or trailers, for example: after an empty hauling vehicle is weighed, it is then changed to a new license plate (heavy vehicle to light vehicle) or trailer (heavy trailer to light trailer) before being loaded.

[0043] The inventor of this application has found that common cheating behaviors currently include the following:

[0044] 1. Tare weighing, loading and gross weighing are three independent links;

[0045] 2. There is still some distance between the truck weighing room and the coal loading and unloading point;

[0046] 3. After the empty truck is weighed, the hauler needs to wait or queue up to load the truck;

[0047] 4. The haulage driver colludes with the weighhouse operator or coal loading personnel;

[0048] 5. Due to space limitations in the coal yard, the boundaries of loading and unloading areas for different types of coal are unclear.

[0049] In summary, the solution of the present application can effectively identify the real type of coal transported by the transport vehicle, thereby effectively curbing and eliminating the cheating behavior of the transport driver to steal coal or replace coal, and ensuring the asset safety of the coal seller.

[0050] Through the combination of the above-mentioned equipment and software algorithms, it is possible to identify any cheating behavior such as stealing coal or replacing coal during the weighing process of coal transport vehicles, and issue early warnings, so that coal sales measurement and settlement are accurate, and the asset safety of coal sellers is guaranteed.

[0051] At the same time, in many fields such as engineering, chemical industry, food, etc. that use automobile cargo boxes for loading and weighing, the patent idea can be used to realize anti-cheating mode in these fields.

[0052] During the specific implementation process, the system also includes an identity verification device, which is communicatively connected to the control device, and the identity verification device is used to verify the vehicle's license plate and / or the driver's identity.

[0053] Specifically, the identity verification device verifies the identity of the vehicle and driver through technologies such as license plate recognition, IC card recognition, QR code scanner, ID card reader, RFID reader, and face recognition, and transmits the verification results to the control device. Figure 2 and Figure 3 As shown, when the vehicle drives to the weighing area of ​​the electronic truck scale, the basic information of the vehicle is automatically identified by the above-mentioned equipment, replacing the manual identification of the vehicle, and is connected to the system workstation 14, automatically triggering the start of the function operation of this system, which can realize the automatic identification of the type of coal by the coal transport vehicle in the link of sales and weighing, and effectively judge whether the transport vehicle has cheated in stealing coal or exchanging coal.

[0054] Specifically, this solution includes a universal truck scale (i.e., electronic truck scale), a laser radar device with a pan / tilt function (i.e., laser scanner) installed on the top of the universal truck scale, a system workstation connected to the communication signal between the universal truck scale and the laser radar, and coal type identification and anti-theft and cheating system software running in the system workstation. Optional license plate recognition devices, IC card readers, QR code scanners, ID card readers, RFID readers and other identity recognition and verification devices can replace manual vehicle recognition and automatically trigger the start of the system's functional operations.

[0055] Specifically, the process of coal truck transportation is as follows:

[0056] (1) Before loading, the transport vehicle must first drive to the truck scale to weigh the vehicle's tare weight. After the transport vehicle stops in the weighing area, the truck scale completes the tare weighing, and at the same time, the laser radar is started, the pan / tilt moves, and the empty truck bed volume is scanned. The length, width, and depth of the truck bed when the transport vehicle is empty are measured and three-dimensionally modeled. At the same time, the height of the truck bed top from the truck scale plane is measured (by reverse calculation from the known laser radar equipment to the truck scale plane). The coal type identification and anti-theft cheating system software in the system workstation obtains the tare weight of the vehicle and the 3D modeling of the volume of the empty truck bed.

[0057] (2) After loading, the transport vehicle must drive to the truck scale to weigh the gross weight of the vehicle. After the transport vehicle stops in the weighing area, the truck scale completes the gross weight measurement. At the same time, the laser radar is started, the pan / tilt moves, and the volume of the heavy vehicle bucket is scanned to measure the loading condition of the heavy vehicle bucket and three-dimensionally model it. At the same time, the height of the bucket top from the truck scale plane is measured (by reverse calculation from the known laser radar equipment to the truck scale plane). The coal type identification and anti-theft cheating system software in the system workstation obtains the gross weight of the vehicle and the 3D modeling of the volume of the heavy vehicle bucket.

[0058] (3) The coal type identification and anti-theft and cheating system software calculates the weight obtained from the two weighing scans and the 3D modeling of the truck bed volume.

[0059] The net weight (gross weight - tare weight) is calculated based on the weighing quantity when the vehicle is weighed twice.

[0060] The actual loading volume of the truck bed is calculated based on the 3D modeling data of the truck bed volume when the vehicle is weighed twice. Since the tire and shock absorber travel of the vehicle is reduced after the heavy vehicle is loaded, the height difference between the top of the truck bed and the scale plane when the vehicle is weighed twice must be calculated first, and then corrected in the volume comparison to calculate the actual loading volume.

[0061] If the length and width of the two 3D modeling of the truck bed volume are inconsistent, the system will issue an alert that the vehicle has changed its license plate or suspension.

[0062] If the length and width of the two 3D modeling of the truck bed volume are consistent, the actual volume density ratio of each truck can be calculated based on the formula ρ=m / V, that is, volume density ratio (density)=mass / volume.

[0063] According to the characteristics of coal, it is divided into three major categories and their subcategories: bituminous coal, lignite, anthracite, and their density values ​​are different. According to the appearance of coal, it is mainly divided into gangue, coal slime, foamy coal, mixed coal, granular coal, lump coal, etc., and the bulk density ratio is also in their respective ranges.

[0064] To ensure that this system can meet the coal types at the application site and accurately identify coal types (including custom coal types), it needs to run for a certain period of time after installation to accumulate and analyze data, that is, to obtain the average value of the known coal type after a certain number of transportations, which is the bulk density ratio of the coal type, and set the upper and lower ranges (proportions) at the same time.

[0065] When the range is exceeded, the system will issue an alert. For example: the transport vehicle should transport foam coal, but the actual calculated bulk density ratio of lump coal shows cheating behavior of replacing the type of coal; the water tank of the transport vehicle is filled with 1 ton of water before the empty scale is weighed, and the actual load is 40 tons. All the water is unloaded before the heavy scale is weighed, and the net weight calculated by the truck scale is 39 tons. The difference in the scanned truck bed volume is 50 cubic meters. The normal bulk density should be 40 / 55=0.7273, but the actual density is 39 / 55=0.7091 (the above data is only for example, not real data). There is cheating behavior that the actual transported weight is greater than the settlement weight.

[0066] The linear changes of mass, volume and bulk density ratio can also be used to guide the calibration of general vehicle scales.

[0067] If the empty vehicle and the loaded vehicle are not weighed on the same truck scale, a laser radar device with a pan / tilt function must be installed at the same height above the two universal truck scales and connected to the system workstation at the same time.

[0068] At the same time, in many fields such as engineering, chemical industry, food, etc. that use automobile cargo boxes for loading and weighing, the patent idea can be used to realize anti-cheating mode in these fields.

[0069] Specifically, the system of the present application consists of a universal electronic truck scale, a laser radar truck bed loading (empty / heavy) scanning device with a pan / tilt platform, a system workstation, coal type identification and anti-theft and cheating system software, and optional license plate recognition devices such as IC card recognition or QR code scanner or ID card reader or RFID reader can be used to replace manual vehicle identification and automatically trigger the start of the system's functional operations.

[0070] The above-mentioned general electronic truck scale, commonly known as floor scale, is mainly used for weighing bulk goods. It is mainly composed of load carrier, weighing display instrument, weighing sensor, connector, limit device and junction box. When an empty or loaded car drives onto the load carrier, under the action of gravity, one or more groups of weighing sensors under the load carrier will transmit the weighing value to the weighing display instrument for display. The weighing display instrument is also connected to the system workstation to transmit the weighing value results.

[0071] The above-mentioned laser radar bucket loading (empty / loaded) scanning device with a pan-tilt is mainly used to scan and obtain the basic dimensions of the length, width and height of the bucket of the hauling vehicle, as well as the actual volume of the bucket when empty or loaded. In order to ensure that the buckets of hauling vehicles of different lengths, widths and heights can be fully covered and scanned, the laser radar equipment has a pan-tilt rotation function. When the laser radar is in operation, it is linked with the pan-tilt and rotates to complete the scanning of the entire area of ​​the bucket. The device is connected to the system workstation, which issues commands for control, and finally obtains the scanned volume results.

[0072] The above-mentioned system workstation is a high-end general-purpose microcomputer mainly used for specific application fields, with a friendly human-machine interface and an efficient working platform. The workstation is mainly used to carry the basic hardware operating environment of the coal type identification and anti-theft and cheating system software.

[0073] The above-mentioned coal type identification and anti-theft and cheating system software is mainly used for controlling the laser radar truck bed loading (empty / heavy) scanning device, generating the scanning volume results, and calculating or comparing the difference between the empty and heavy volumes. If the length, width and height of the (empty / heavy) truck bed are inconsistent (exceeding the error ratio range), the system will alarm and manually intervene to check the vehicle; obtain the (empty / heavy) weighing tare weight and gross weight of the general electronic truck scale to calculate the actual net weight; according to the formula ρ=m / V (bulk density ratio (density)=mass / volume), a bulk density ratio database for different types of coal is established. After running for a certain period of time, the average bulk density ratio of each type of coal is calculated based on the data accumulation, and some problematic volume and mass combinations are eliminated according to the upper and lower limit ratios. After preliminarily correcting the average bulk density ratio, the warning upper and lower limit ratios are set. After the warning is activated, when the new transport vehicle (empty / heavy) exceeds the upper and lower limits of the average bulk density ratio of the transported coal type after overweighing, the system will alarm and manually intervene to check the vehicle.

[0074] The above-mentioned license plate recognition device, IC card reader, QR code scanner, ID card reader, RFID reader and other identity recognition and verification devices are optional equipment. When the vehicle drives to the weighing area of ​​the universal electronic truck scale, the above-mentioned equipment will automatically identify the basic information of the vehicle, replacing manual identification of the vehicle, and connect to the system workstation to automatically trigger the start of the function operation of this system.

[0075] In addition to the above hardware configuration and installation, the specific implementation and core of the solution of this application are as follows:

[0076] The accuracy of laser radar equipment selection is due to the large number of imported and domestic laser radar equipment currently available. It is necessary to ensure that the error range of the selected equipment is within a reasonable range and that the error rate between the cumulative average calculated bulk density ratio of different types of coal and the actual one is low.

[0077] Whether the installation height of the laser radar and the rotation angle of the gimbal can fully cover and scan the entire truck bed range. Because coal-hauling vehicles have different lengths, it is necessary to ensure that the laser radar + gimbal scanning method can cover the entire truck bed range.

[0078] In the coal type identification and anti-theft and cheating system software, the results of two truck bed volume scans are compared and the volume difference calculation algorithm is used.

[0079] The laser radar scanning sensor is used to scan the material cross-sections of empty and loaded vehicles to obtain the overall cross-sectional curve of the material. After algorithm processing, the information such as the length, width and height of the vehicle bed, volume, characteristic coordinates, and three-dimensional point cloud images are output.

[0080] If the length and width of the 3D volume modeling of the truck bed scanned twice are consistent, and the height of the tires and shock absorbers of the transporting vehicle is reduced due to the loaded weight, the horizontal height of the empty or loaded vehicle can be corrected by subtracting the edge height of the truck bed from the edge height of the loaded vehicle bed. This will allow the two 3D volume models to be at the same horizontal height, and then the difference can be calculated to work out the actual loaded volume.

[0081] Establishment, data accumulation and correction of the database of mass, volume and bulk density ratio of each type of coal.

[0082] The complete empty and loaded vehicle weighing and lidar scanning results of a certain type of coal in a certain period or a certain number of trains are continuously accumulated in the database, and the real-time average value is calculated to obtain the benchmark warning value for the type of coal. By setting the upper and lower warning ratio thresholds, vehicles with problems can be warned and inspected through manual intervention.

[0083] At the same time, invalid data should be eliminated through manual intervention or automatic machine correction to make the accuracy of the benchmark warning value of the bulk density ratio of different types of coal higher and higher. Manual intervention includes eliminating the abnormal behavior data of vehicles that have been found and confirmed, eliminating invalid data due to abnormalities of equipment such as vehicle scales and laser radars, and eliminating data that is not representative through scatter diagrams drawn by the system. Automatic machine correction can set the bulk density ratio threshold and automatically eliminate data outside the threshold.

[0084] Optional license plate recognition device, IC card reader, QR code scanner, ID card reader, RFID reader and other identity recognition and verification devices can replace manual vehicle recognition (unattended weighing room mode) and automatically trigger the start of the system's functional operation.

[0085] In this embodiment, a control method for a coal transportation anti-cheating system running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0086] Figure 4 It is a flow chart of a control method of a coal transportation anti-cheating system according to an embodiment of the present application.

[0087] like Figure 4 As shown, the method comprises the following steps:

[0088] Step S201, obtaining the weight of the vehicle;

[0089] Specifically, the vehicle weight data is collected in real time through the electronic truck scale sensor, and the weight data is transmitted to the control device via wired or wireless means. The control device stores the collected weight data in a local database or cloud server to facilitate timely processing in subsequent steps.

[0090] Step S202, obtaining the volume of the vehicle, wherein the volume is obtained by scanning with a laser scanner;

[0091] Specifically, the laser scanner performs an all-round scan of the vehicle's profile to generate a three-dimensional model of the vehicle. The scanned data is processed by the control device to calculate the volume of the vehicle, and the control device stores the volume data and weight data synchronously for subsequent calculations.

[0092] Step S203, calculating the bulk density ratio according to the weight and volume;

[0093] Specifically, the control device reads the stored weight and volume data, calculates the vehicle's volume-to-weight ratio according to the formula (net weight / volume), and stores the calculation result in a local database or cloud server.

[0094] Step S204: When the difference between the volume-to-weight ratio and the preset volume-to-weight ratio is less than the preset difference, cheating is determined and a first alarm message is generated.

[0095] Specifically, the control device compares the calculated volume weight ratio with the preset standard volume weight ratio. If the difference between the volume weight ratio and the preset volume weight ratio is less than the preset difference, the system determines that the driver has cheated. The system generates a first alarm message and sends it to the monitoring center or relevant management personnel, who manually intervene to check the vehicle. The alarm message and related data are saved in the database for subsequent verification and processing.

[0096] In the actual implementation process, the system can collect the empty and loaded vehicle weighing and laser scanning data of a specific type of coal within a certain period or train, continuously update the database, and calculate the real-time average value to determine the baseline warning value of the coal. At the same time, set the upper and lower limit thresholds of the warning ratio to provide warnings and manual inspections for abnormal vehicles. In order to improve the accuracy of the benchmark warning values ​​of the bulk density ratio of different types of coal, it is necessary to exclude invalid data manually or automatically. Manual intervention includes removing confirmed vehicle abnormal behavior data and invalid data caused by equipment abnormalities, as well as excluding meaningless data through tools such as scatter plots generated by the system. Automatic machine correction can automatically identify and exclude data that exceeds the normal range by setting the bulk density ratio threshold, thereby continuously improving the accuracy and reliability of the early warning system.

[0097] In summary, the control method of the anti-cheating system for coal transportation in the embodiment of the present application collects vehicle weight data in real time through the electronic truck scale sensor and the laser scanner scans the vehicle contour in all directions to calculate the volume, and then calculates the bulk density ratio. When the difference between the bulk density ratio and the preset value is less than the preset difference, the system determines cheating and generates an alarm message, promptly discovers and prevents the driver's cheating behaviors such as stealing coal, changing coal, and injecting water, thereby improving the overall efficiency and management level of coal transportation, effectively solving the cheating problem in the coal transportation process, and ensuring the fairness and accuracy of transportation.

[0098] Specifically, for the detection of actual hauling weight being greater than the settled weight, when the vehicle is unloaded and weighed, the volume and tare weight of the bucket are recorded; when the vehicle is loaded with coal, the volume and gross weight of the bucket after loading are recorded. By comparing the difference between the empty and loaded bucket volumes, the actual volume of the loaded coal is calculated, and then combined with the difference between the gross weight and tare weight (i.e., net weight), the bulk density ratio formula is used for verification. If the net weight converted from the actual loaded volume does not match the net weight measured by the truck scale, and the actual net weight is significantly greater than the measured net weight, the system will trigger an early warning, indicating possible weight cheating.

[0099] When a truck is weighed empty, the tare weight is recorded as 10 tons, and the volume of the truck bed scanned by the LiDAR is 24 cubic meters. After loading coal, the gross weight is recorded as 54 tons. The relative height between the top of the truck bed and the ground is reduced when it is overloaded. After the LiDAR correction, the volume of the loaded truck bed is 48 cubic meters. According to the bulk density ratio formula, the net weight converted from the actual loading volume should be (48-24)=24. If the average bulk density ratio of this type of coal in the database is 0.7, then the actual net weight should be 16.8 tons. However, the net weight measured by the truck scale is 44 tons (54-10). There is a large difference between the actual net weight and the measured net weight, indicating that there may be weight cheating.

[0100] Specifically, for the detection of the behavior of stealing coal, the system is based on the principle of bulk density ratio, and uses the average bulk density ratio of different coal types in the database to determine whether the type of coal loaded on the vehicle is consistent with the type of coal declared. If the vehicle declares to load low-value coal, and the bulk density ratio after loading is close to that of high-value coal, the system will trigger an early warning, indicating that there may be a behavior of stealing coal.

[0101] A vehicle was declared to be loaded with bituminous coal (a low-value coal type), and its average bulk density ratio is 0.7. After weighing empty, the recorded tare weight was 12 tons, and the truck bed volume was 26 cubic meters. After weighing loaded, the gross weight was recorded as 50 tons, and the corrected truck bed loading volume was 42 cubic meters. The actual loaded net weight was calculated to be (42-26=16) cubic meters, which converted to a weight of 11.2 tons. However, the net weight measured by the truck scale was 38 tons (50-12), and the calculated bulk density ratio was 2.375, which is much higher than the average bulk density ratio of bituminous coal, and close to the bulk density ratio of lump coal (a high-value coal type). The system will trigger an early warning, indicating that there may be an act of stealing coal types.

[0102] Specifically, for the detection of vehicle license plate or suspension change, the system obtains the vehicle's identity information through license plate recognition, IC card recognition and other equipment, and compares it with the previous weighing record. If the vehicle identity information recorded in the unloaded weighing record is inconsistent with the vehicle identity information recorded in the loaded weighing record, or the length, width and height of the truck bed change significantly during the two weighings (exceeding the set error ratio range), the system will trigger an early warning, indicating that the vehicle may have changed its license plate or suspension.

[0103] When a vehicle is weighed empty, the license plate recognition device records its license plate as A12345, and the volume scan of the truck bed is 5 meters long, 2.5 meters wide, and 2 meters deep. After being weighed loaded with coal, the license plate recognition device still records the license plate as A12345, but the volume scan of the truck bed is 5.5 meters long, 2.7 meters wide, and 2.1 meters deep. Since the length and width of the truck bed have changed significantly during the two weighings, exceeding the set error ratio range, the system will trigger an early warning, indicating that the vehicle may have changed its license plate or suspension, which requires further manual verification and confirmation.

[0104] In the specific implementation process, the above step S201 can be implemented by the following steps:

[0105] Step S301, obtaining point cloud data of the vehicle, wherein the point cloud data is obtained by scanning with a laser scanner;

[0106] Specifically, the method uses a laser scanner to scan the material cross-section of the vehicle in all directions to obtain the cross-sectional curve of the entire material. After algorithm processing, the method outputs information such as the length, width, height, volume, characteristic coordinates, and three-dimensional point cloud images of the vehicle, generates point cloud data of the vehicle, and provides high-precision three-dimensional information. Point cloud data is a collection of three-dimensional coordinates that describe a point in space. The laser scanner transmits the collected point cloud data to the control device via wired or wireless means.

[0107] Step S302, performing three-dimensional modeling according to the point cloud data to obtain a three-dimensional model of the vehicle, wherein the three-dimensional model includes three-dimensional information of the vehicle, and the three-dimensional information includes length, width and height;

[0108] Specifically, the control device processes the point cloud data and converts the discrete point cloud data into a continuous three-dimensional model through an algorithm, thereby providing comprehensive three-dimensional information, which can more intuitively understand the vehicle's geometric structure and facilitate subsequent data analysis and processing.

[0109] Step S303, calculate the product of the length, width and height to obtain the volume.

[0110] Specifically, the control device reads the length, width and height of the vehicle from the stored three-dimensional model, and calculates the volume of the vehicle according to the formula (volume = length × width × height). It can be seen that through these steps, the coal transportation anti-cheating system can efficiently and accurately measure the volume of the vehicle, providing a reliable data basis for subsequent volume-to-weight ratio calculation and anti-cheating analysis.

[0111] In some embodiments, the above step S203 can be specifically implemented by the following steps: calculate the volume-to-weight ratio according to the target formula, wherein the target formula is ρ=m / V, ρ represents the volume-to-weight ratio, m represents the weight difference between the first weight and the second weight, the first weight is the tare weight of the vehicle before loading, the second weight is the gross weight of the vehicle after loading, and V represents the volume. This method calculates the accurate volume-to-weight ratio through precise weight and volume data and the target formula ρ=m / V, ensuring the accuracy and reliability of the data. Accurate volume-to-weight ratio data provides a reliable basis for subsequent anti-cheating analysis, and can more effectively identify and prevent drivers' cheating behavior.

[0112] In the specific implementation process, the above step S203 also includes the following steps:

[0113] Step S401, obtaining a first height, wherein the first height is the height of the top of the bucket relative to the ground when the vehicle is empty;

[0114] Specifically, when the vehicle is in an unloaded state and overbalanced, the lidar equipment will measure the vertical distance of the top of the cargo box relative to the ground. Through the height sensor or laser rangefinder, the height of the top of the cargo box relative to the ground when the vehicle is in an unloaded state is measured, that is, the first height. The height data is transmitted to the data processing unit via wired or wireless means. The first height data is stored synchronously with other measurement data of the vehicle to ensure data consistency.

[0115] Step S402, obtaining a second height, wherein the second height is the height of the top of the bucket relative to the ground when the vehicle is in a loaded state;

[0116] Specifically, after the vehicle is loaded with coal, when it is weighed again, the laser radar equipment also measures the vertical distance of the top of the truck bed relative to the ground. When the vehicle is in a loaded state, the same height sensor or laser rangefinder is used to measure the height of the top of the truck bed relative to the ground, i.e., the second height. The second height data is stored synchronously with other measurement data of the vehicle to ensure data consistency.

[0117] Step S403, correcting the second height according to the first height so that the first height and the second height are the same, thereby obtaining a corrected second height;

[0118] Specifically, after the vehicle is loaded with coal, the tires and shock absorbers will be compressed under the action of gravity, causing the vehicle body to sink, and the second height will be smaller than the first height. The system will use the first height as a reference, and by calculating the difference between the two heights, correct the second height so that it is mathematically equal to the first height, thereby obtaining the corrected second height. The control device reads the stored first and second heights, and corrects the second height to be the same as the first height through an algorithm, ensuring that the vehicle has the same reference height when empty and loaded. Through height correction, the measured height of the vehicle in different states is ensured to be consistent, thereby improving the accuracy of the data.

[0119] Step S404, correcting the current volume of the vehicle according to the corrected second height to obtain a corrected volume.

[0120] Specifically, the control device reads the corrected second height and the current volume, and uses an algorithm to correct the current volume according to the corrected second height to ensure the accuracy of the volume data. Based on the corrected second height, the system software will recalculate the volume of the truck bed after loading coal to eliminate the impact of the car body sinking. The corrected volume more accurately reflects the actual amount of coal loaded.

[0121] It can be seen that the laser scanner is used to scan the cross section of the material of the empty truck and the loaded truck to capture the overall cross-sectional curve of the material. Through algorithm processing, the system can output detailed information such as the length, width, height, volume, characteristic coordinates, and three-dimensional point cloud image of the truck bucket. In the two scans, if the length and width of the 3D model of the truck bucket are the same, but the height of the vehicle tires and shock absorbers is reduced due to the loaded weight, the horizontal plane height can be adjusted by calculating the difference in the height of the edge of the empty truck and the loaded truck bucket to ensure that the two 3D volume models are on the same horizontal plane. After this correction, the system can accurately calculate the difference and obtain the actual volume of the loaded material. The coal hauling anti-cheating system can efficiently and accurately correct the height and volume data of the vehicle, providing a reliable basis for the subsequent volume-to-weight ratio calculation and anti-cheating analysis, and can more effectively identify and prevent drivers' cheating behavior.

[0122] In some embodiments, after the above step S202, the following steps are also included:

[0123] Step S501, obtaining a first volume, wherein the first volume is the volume of the truck bed when the vehicle is empty;

[0124] Step S502, obtaining a second volume, wherein the second volume is the volume of the truck bed when the vehicle is in a loaded state;

[0125] Specifically, the volume of the bucket when the vehicle is empty is measured by a laser scanner, i.e., the first volume. When the vehicle is loaded, the same laser scanner is used to measure the volume of the bucket, i.e., the second volume. The volume data is transmitted to the control device by wire or wireless means, and the second volume data is synchronously stored with the first volume data to facilitate subsequent comparison and analysis.

[0126] Step S503: When the volume difference between the first volume and the second volume is greater than a preset volume difference, cheating is determined and a second alarm message is generated.

[0127] Specifically, the control device reads the stored first volume and second volume, calculates the difference between the first volume and the second volume, and compares it with a preset volume difference. If the difference is greater than the preset volume difference, the system determines that the driver has cheated. The system generates a second alarm message and sends it to the monitoring center or relevant management personnel. The alarm message and related data are saved in the database for subsequent verification and processing.

[0128] It can be seen that this method provides high-precision volume measurement through the laser scanner. By calculating and comparing the volume difference, the system automatically judges and generates alarm information, which can more effectively identify and prevent drivers' cheating behaviors such as stealing coal and changing coal, reduce manual intervention, and improve anti-cheating efficiency.

[0129] The embodiment of the present application also provides a control device for a coal transportation anti-cheating system.

[0189] From the above description, it can be seen that the above embodiments of the present application achieve the following technical effects:

[0190] 1) The anti-cheating system for coal transportation of the present application includes: an electronic truck scale, a laser scanner and a control device. Among them, the electronic truck scale is used to weigh the vehicle to obtain the weight of the vehicle; the laser scanner is used to scan the vehicle to obtain the volume of the vehicle; the control device is connected to the electronic truck scale and the laser scanner for communication, and the control device is used to determine the bulk density ratio according to the scanned weight and volume, and determine cheating when the difference between the bulk density ratio and the preset bulk density ratio is less than the preset difference. In this scheme, a laser scanner is newly added to the existing vehicle weighing system, so that not only the weight of the vehicle can be determined by the electronic truck scale, but also the volume of the vehicle can be scanned by the laser scanner. The bulk density ratio can be calculated by these two parameters. The bulk density ratio will be preset when each vehicle is transported. If the driver cheats by stealing coal, changing coal or injecting water, etc., there will be a difference between the actual measured bulk density ratio and the pre-configured bulk density ratio, and the driver can be determined to be cheating at this time. This application effectively identifies the cheating behavior of the driver through multi-parameter measurement and automated analysis, and solves the problem that the coal transporting driver may have cheating behavior.

[0191] 2) The control method of the anti-cheating system for coal transportation of the present application collects vehicle weight data in real time through the electronic truck scale sensor and the laser scanner scans the vehicle contour in all directions to calculate the volume, and then calculates the bulk density ratio. When the difference between the bulk density ratio and the preset value is less than the preset difference, the system determines cheating and generates an alarm message, timely discovers and prevents the driver's cheating behaviors such as stealing coal, changing coal, and injecting water, improves the overall efficiency and management level of coal transportation, effectively solves the cheating problem in the coal transportation process, and ensures the fairness and accuracy of transportation.
