Description

Technical Field

[0001] This invention relates to the field of vehicle weighing technology, and in particular to a vehicle handling method and apparatus based on a truck scale. Background Technology

[0002] Currently, truck scales are widely used for highway toll collection and overload detection. However, truck scale weighing still relies primarily on manual labor. Truck scale inspection sites experience high traffic volume and speed, harsh environments, and demanding work conditions for personnel, leading to high risks. The lack of a reasonable and orderly weighing method further reduces the efficiency of the weighbridge. Additionally, the absence of preventative measures against unauthorized entry and following of other vehicles increases the risk of accidents.

[0003] Therefore, the present invention provides a vehicle handling method and apparatus based on a truck scale. Summary of the Invention

[0004] This invention provides a vehicle handling method and device based on a truck scale, which can determine whether the vehicle is parked outside the designated area and whether the driver's operation is in accordance with regulations by monitoring the vehicle loading process in real time. When the above problems occur, the control command terminal and the vehicle terminal remotely communicate and command the vehicle. After the vehicle measurement and verification is completed, the vehicle is guided to leave. This provides a method for orderly vehicle measurement and improves the working efficiency of the weighbridge.

[0005] This invention provides a vehicle handling method based on a truck scale, comprising:

[0006] Step 1: Determine the current vehicle's direction of entry onto the weighbridge by sequentially sensing the load-bearing sensors on the weighbridge;

[0007] Step 2: When the weighing direction is in the normal weighing state, monitor the weighing process of the current vehicle in real time, and determine whether the current vehicle is parked outside the boundary and whether the driver's operation is in accordance with regulations.

[0008] Step 3: When there is a high probability of parking outside the boundary or improper operation, control the vehicle's on-board unit to establish a remote communication connection with the command terminal of the weighbridge, and provide intelligent command for the vehicle.

[0009] Step 4: After the command is completed, send the verification information to the vehicle terminal of the current vehicle. After the information is successfully verified, control the front gate of the current vehicle to be open and the rear gate to be closed, so as to guide the current vehicle to leave.

[0010] Preferably, the current vehicle's orientation on the weighbridge is determined by the sequential sensing results of the load cells on the weighbridge, including:

[0011] When a vehicle drives onto the weighbridge, the sequential sensing results of the weighbridge's load-bearing sensors are obtained.

[0012] The sensing results are sorted, and the current vehicle's weighing direction is determined based on the position of the corresponding sensing results;

[0013] Based on the direction of the vehicle to be weighed, the front gate of the current vehicle is controlled to be closed and the front traffic light is controlled to be red to guide the current vehicle to the weighbridge.

[0014] Preferably, the sensing results are sorted, and the current vehicle's weighing direction is determined based on the position of the corresponding sensing results, including:

[0015] The positions corresponding to the sensing results are sorted in ascending order based on the sensing results.

[0016] The locations corresponding to the sensing results are sorted a second time according to the location distribution;

[0017] Based on the matching trajectories of the first and second sorting, determine the current vehicle's weighing direction.

[0018] Preferably, when the weighing direction is in a normal weighing state, the weighing process of the current vehicle is monitored in real time, and it is determined whether the current vehicle is parked outside the boundary and whether the driver's operation is standardized, including:

[0019] The current vehicle's weighing speed is determined by real-time monitoring, which determines whether the vehicle is suspected of running away from the weighbridge, whether the weighing is stable, and whether the vehicle is in a normal weighing state.

[0020] When the current vehicle is in a normal weighing state, the weighing process of the current vehicle is acquired;

[0021] Based on the compliance standards of the weighing process analysis, determine whether the driver's operation is in accordance with regulations;

[0024] Multiple standard steps to obtain process compliance standards;

[0025] The weighing process is divided into multiple parts, and each part is marked with a corresponding step number and sequence number according to the standard steps. The missing and redundant steps in the weighing process are then determined.

[0026] Determine whether the step numbers and sequence numbers of the same part are the same; if they are different, identify the incorrect steps in the out-of-order part.

[0030] Based on the correlation between the redundant steps and all steps in each part, determine the third effect of the redundant steps on each part.

[0031] A compliance assessment is conducted on the same part based on the first, second, and third impacts of the same part to determine the compliance of the corresponding part.

[0032] Based on the compliance of each part, determine the likelihood of operational irregularities.

[0033] Preferably, the specified boundary is determined based on the location of the load cell and the model of the current vehicle, including:

[0034] Based on the location and model of the load cells, determine the primary and secondary sensing ranges of each load cell.

[0038] The measurement error is determined based on the actual mass and the first weighing result, and the second weighing result corresponding to the measurement error being within a preset error range is determined.

[0039] Based on the position corresponding to the second weighing result, the specified boundary of the corresponding vehicle model is obtained.

[0040] Preferably, when there is a high probability of events such as parking outside the designated area or improper operation, the vehicle's on-board unit is remotely connected to the weighbridge control unit, and intelligent control is provided for the vehicle, including:

[0041] When the current vehicle stops outside the boundary, the current vehicle is directed to enter the designated boundary according to the situation of the outside boundary.

[0042] When the current vehicle has a high probability of an operational error, the operational error of the high probability event is determined.

[0043] Based on the code of conduct, determine the methods for handling non-standard operating behaviors and instruct the driver accordingly.

[0044] Preferably, after the command is completed, verification information is sent to the vehicle's onboard unit. Upon successful verification, the front gate of the current vehicle is opened, and the rear gate is closed, guiding the vehicle to depart. This includes:

[0053] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description, claims, and drawings.

[0054] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0055] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used in conjunction with embodiments of the invention to explain the invention and do not constitute a limitation thereof. In the drawings:

[0056] Figure 1 This is a flowchart of a vehicle processing method based on a truck scale according to an embodiment of the present invention;

[0057] Figure 2 This is a structural diagram of a vehicle handling device based on a truck scale according to an embodiment of the present invention. Detailed Implementation

[0058] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0059] This invention provides a vehicle handling method based on a truck scale, such as... Figure 1 As shown, it includes:

[0060] Step 1: Determine the current vehicle's direction of entry onto the weighbridge by sequentially sensing the load-bearing sensors on the weighbridge;

[0061] Step 2: When the weighing direction is in the normal weighing state, monitor the weighing process of the current vehicle in real time, and determine whether the current vehicle is parked outside the boundary and whether the driver's operation is in accordance with regulations.

[0062] Step 3: When there is a high probability of parking outside the boundary or improper operation, control the vehicle's on-board unit to establish a remote communication connection with the command terminal of the weighbridge, and provide intelligent command for the vehicle.

[0063] Step 4: After the command is completed, send the verification information to the vehicle terminal of the current vehicle. After the information is successfully verified, control the front gate of the current vehicle to be open and the rear gate to be closed, so as to guide the current vehicle to leave.

[0064] In this embodiment, the weighing direction is determined by sorting the sensing results and based on the position of the sensing results. For example, the positions are sorted from smallest to largest according to the sensing results as position 1, position 2, position 3, and position 4. The position order itself is position 1, position 2, position 3, and position 4. Since the order is the same, the weighing direction is from position 4.

[0065] In this embodiment, a normal weighing state means that the vehicle has no suspicion of running away from the weighbridge and is stable on the weighbridge. Whether the vehicle is parked outside the boundary is determined by establishing a weighing model based on information such as the position of the weighing sensor, and then determining the prescribed boundary based on the simulated weighing results of different vehicles. Whether the vehicle exceeds the prescribed boundary is determined by the compliance of each part of the weighing process.

[0066] In this embodiment, a high-probability event refers to an event where the probability of the driver's operation being non-standard is greater than the preset probability. The preset probability is set in advance. The command terminal refers to the manual command terminal, which is connected to the vehicle terminal via wireless intercom.

[0067] In this embodiment, intelligent command selects how to command based on vehicle problems; for example, if a vehicle goes out of bounds, it commands the vehicle to return to the boundary.

[0068] In this embodiment, the information to be verified refers to vehicle weighing information, vehicle license plate information, etc.

[0069] The beneficial effects of the above technical solution are: by monitoring the vehicle weighing process in real time, it can determine whether the vehicle is parked outside the boundary and whether the driver's operation is standardized. When the above problems occur, the control and command terminal and the vehicle terminal can communicate remotely and command the vehicle. When the vehicle measurement and verification are completed, the vehicle is guided to leave. This provides a method for orderly vehicle measurement and improves the working efficiency of the weighbridge.

[0070] This invention provides a vehicle handling method based on a truck scale, which determines the current vehicle's direction of entry onto the scale by sequentially sensing the load-bearing sensors on the truck scale, including:

[0071] When a vehicle drives onto the weighbridge, the sequential sensing results of the weighbridge's load-bearing sensors are obtained.

[0072] The sensing results are sorted, and the current vehicle's weighing direction is determined based on the position of the corresponding sensing results;

[0073] Based on the direction of the vehicle to be weighed, the front gate of the current vehicle is controlled to be closed and the front traffic light is controlled to be red to guide the current vehicle to the weighbridge.

[0074] In this embodiment, the direction of the vehicle onto the weighbridge is determined by sorting the positions of the load cells according to their magnitude based on the sensing results of the load cells and the order of their positions.

[0075] The beneficial effects of the above technical solution are: by using the sequential sensing results of the load-bearing sensors to determine the direction of the vehicle onto the weighbridge, controlling the front gate of the vehicle to be closed and controlling the traffic lights to be red, the vehicle can be guided onto the weighbridge, which can effectively prevent vehicles from running away from the weighbridge.

[0076] This invention provides a vehicle handling method based on a truck scale, which sorts the sensing results and determines the current vehicle's direction of entry onto the scale based on the position of the corresponding sensing results, including:

[0077] The positions corresponding to the sensing results are sorted in ascending order based on the sensing results.

[0078] The locations corresponding to the sensing results are sorted a second time according to the location distribution;

[0079] Based on the matching trajectories of the first and second sorting, determine the current vehicle's weighing direction.

[0080] In this embodiment, for example, the first order is position 1, position 2, position 3, position 4, and the second order is position 4, position 3, position 2, position 1. The first and second orders are opposite and the vehicle is weighed from position 4.

[0081] The beneficial effects of the above technical solution are: by sorting the positions corresponding to the sensing results and sorting the position distribution, the direction of the vehicle on the weighbridge can be determined, laying the foundation for subsequent vehicle guidance.

[0082] This invention provides a vehicle handling method based on a truck scale. When the vehicle is in a normal weighing direction, the method monitors the current vehicle's weighing process in real time and determines whether the vehicle is parked outside the designated area and whether the driver's operation is standardized. The method includes:

[0083] The current vehicle's weighing speed is determined by real-time monitoring, which determines whether the vehicle is suspected of running away from the weighbridge, whether the weighing is stable, and whether the vehicle is in a normal weighing state.

[0084] When the current vehicle is in a normal weighing state, the weighing process of the current vehicle is acquired;

[0085] Based on the compliance standards of the weighing process analysis, determine whether the driver's operation is in accordance with regulations;

[0086] Based on the location of the load sensor and the model of the current vehicle, a defined boundary is determined, thereby determining whether the current vehicle is parked outside the boundary.

[0087] In this embodiment, the weighing speed is determined by the weighing speed. The suspicion of running over the weighbridge is determined by the weighing speed. If the weighing speed is greater than the preset speed, there is a suspicion of running over the weighbridge. The preset speed is set in advance. Whether the weighing is stable is determined by the angle at which the vehicle enters the weighbridge. Normal weighing state means that there is no suspicion of running over the weighbridge and the weighing is stable.

[0088] In this embodiment, the listing process is analyzed according to compliance standards. The listing process is divided into multiple parts. Based on the standard steps of the compliance standards, missing, redundant, and out-of-order steps in each part are identified. The compliance of each part is determined by analyzing the impact of out-of-order steps on the process and the impact of missing and redundant steps on each part, thus obtaining the compliance standard for the listing process. In this embodiment, the defined boundaries are obtained by determining all positions where the vehicle's weighing result on the weighbridge is less than a preset error based on a weighing model. Whether a vehicle is parked outside the boundaries is determined by taking still images of the vehicle to determine if its range exceeds the defined boundaries.

[0089] The beneficial effects of the above technical solution are: by determining that the vehicle is in a normal weighing state, the weighing process is obtained, and it is determined whether the driver's operation is standardized and whether the vehicle is parked outside the boundary, which lays the foundation for providing timely command services to the vehicle in the future.

[0090] This invention provides a vehicle handling method based on a truck scale, which determines whether the driver's operation is in compliance with regulations based on the compliance standards of the weighbridge process analysis, including:

[0091] Multiple standard steps to obtain process compliance standards;

[0092] The weighing process is divided into multiple parts, and each part is marked with a corresponding step number and sequence number according to the standard steps. The missing and redundant steps in the weighing process are then determined.

[0093] Determine whether the step numbers and sequence numbers of the same part are the same; if they are different, identify the incorrect steps in the out-of-order part.

[0094] Based on the sequence of the standard steps and the corresponding operations, determine the correlation between different standard steps;

[0095] Based on the correlation between different standard steps, determine the first correlation between each correct step and each incorrect step in the same disordered part and the second correlation between any two disordered parts, and determine the first impact of the disordered part on the process;

[0096] Based on the correlation between the missing step and all steps in each part, determine the second impact of the missing step on each part;

[0097] Based on the correlation between the redundant steps and all steps in each part, determine the third effect of the redundant steps on each part.

[0098] A compliance assessment is conducted on the same part based on the first, second, and third impacts of the same part to determine the compliance of the corresponding part.

[0099] Based on the compliance of each part, determine the likelihood of operational irregularities.

[0100] In this embodiment, the standard steps are determined according to the standard weighing process. For example, in the standard weighing process, the initial weighing speed should be less than 1 m / s.

[0101] In this embodiment, the step number is determined according to the number of the corresponding standard step contained in each part, and the sequence number is determined according to the number of steps in the weighing process. Each part can have multiple steps. Missing steps refer to the corresponding standard steps that are missing in the weighing process, and redundant steps refer to steps in the weighing process other than the standard steps.

[0102] In this embodiment, the out-of-order part refers to the part where all step numbers and sequence numbers do not match. For example, part 1 has step numbers 3, 4, and 6, and sequence numbers 3, 4, and 5. The step number and sequence number of the third step are different. Part 1 is the out-of-order part. The incorrect step is the step that corresponds to sequence 5, which is step 6.

[0103] In this embodiment, Y ij =α×a ij +β×b ij

[0104] Among them, Y ij This indicates the correlation between the i-th and j-th standard steps; a ij This represents the adjacency relationship between the i-th and j-th standard steps. If the i-th and j-th standard steps are sequentially adjacent, the adjacency relationship is determined to be 1; otherwise, it is determined to be 0. ij Let represent the operational relationship between the i-th and j-th standard steps; α and β represent the weights of the adjacent relationship and the operational relationship, respectively.

[0105] In this embodiment, the first correlation is the correlation between the correct and incorrect steps currently existing in the corresponding disordered part, which is selected from the standard part corresponding to the same disordered part, and is used as the first correlation of the disordered part.

[0106] In this embodiment,

[0107] Where W1 represents the first influence of the same disordered part; α1 represents the weight of the same disordered part; Y i0,i1 X represents the first correlation between the i0th correct step and the i1th incorrect step in the same disordered part; n represents the number of correct steps in the same disordered part; n1 represents the number of incorrect steps in the same disordered part; X j0 This indicates the second correlation between the j0th disordered part and the same disordered part; m represents the number of disordered parts excluding the same disordered part.

[0108]

[0109] Among them, X j0 Y represents the second correlation between the j0th disordered part and the same disordered part; i01 This represents the operational correlation between the i01st erroneous step in the j0th disordered part and all erroneous steps in the same disordered part; n1 represents the number of erroneous steps in the j0th disordered part.

[0110] In this embodiment,

[0111] Where W2 represents the second effect of the missing step on the same part; α1 represents the weight of the same part; and l represents the number of missing steps. Y represents the correlation between the k-th missing step and the same part; ki This indicates the correlation between the k-th missing step and the i-th step in the same part; n k This represents the number of missing steps that are related to the same part.

[0112] In this embodiment, the third influence is similar to the second influence. The correlation between the redundant step and the steps in the same part is determined by whether the redundant step will affect the steps in the same part. For example, the redundant step 01 will affect step 2 in the same part. The redundant step 01 and step 2 in the same part are related. The degree of correlation is determined by the degree of influence.

[0113] In this embodiment, Z = 1 - W1 - W2 - W3

[0114] Where Z represents the compliance of the same part; W1 represents the first impact of the same part; W2 represents the second impact of the same part; W3 represents the third impact of the same part; if the same part is not out of order, W1 equals 0.

[0115] In this embodiment, the probability of non-compliance is determined based on the ratio of the number of parts with a compliance rate of less than 90% to the total number of parts.

[0116] The beneficial effects of the above technical solution are as follows: by labeling and sequentially numbering the multiple parts of the weighing process using standard procedures, missing steps, redundant steps, and out-of-order parts are identified. Based on the correlation between standard steps, the correlation of out-of-order parts and their impact on the process are determined. The impact of missing and redundant steps on each part is determined. Based on correct operation and impact, the compliance of each part is determined, thereby identifying the possibility of non-standard operation. Through monitoring and analysis, the pressure on staff is reduced, and the assessment of the driver's operation compliance is more accurate.

[0123] Based on the position corresponding to the second weighing result, the specified boundary of the corresponding vehicle model is obtained.

[0124] In this embodiment, the primary sensing range refers to the range within which the load-bearing sensor is more sensitive to changes, and the remaining part of the primary sensing range is the secondary sensing range.

[0125] In this embodiment, the parameters of the truck scale refer to parameters such as the platform size of the truck scale, and the weighing model is constructed based on the main and secondary sensing ranges of the load-bearing sensors and the parameters of the truck scale.

[0127] In this embodiment, the vehicle boundary corresponding to each second weighing result is determined, and all vehicle boundaries are included by a larger boundary. This larger boundary is the specified boundary of the corresponding vehicle model.

[0128] The beneficial effects of the above technical solution are: by using the main and secondary sensing ranges of each load cell and the parameters of the truck scale, the weighing model is determined; based on the position of the measurement error of the same model of vehicle on the truck scale within the preset error range, the specified boundary is obtained, which lays the foundation for subsequent determination of whether the vehicle has gone out of bounds.

[0129] This invention provides a vehicle handling method based on a truck scale. When there is a high probability of events such as parking outside the designated area or improper operation, the method controls the on-board unit of the current vehicle to establish a remote communication connection with the command terminal of the weighbridge, and provides intelligent command for the current vehicle, including:

[0130] When the current vehicle stops outside the boundary, the current vehicle is directed to enter the designated boundary according to the situation of the outside boundary.

[0131] When the current vehicle has a high probability of an operational error, the operational error of the high probability event is determined.

[0132] Based on the code of conduct, determine the methods for handling non-standard operating behaviors and instruct the driver accordingly.

[0133] In this embodiment, the behavior manual is determined in advance based on the weighing process standards.

[0134] The beneficial effects of the above technical solution are: by selecting different commands for the vehicle based on different vehicle problems and using remote communication, it provides drivers with a more convenient and intuitive guidance method, which can improve the efficiency of weighbridge operation.

[0135] This invention provides a vehicle handling method based on a weighbridge. After the command is completed, verification information is sent to the on-board unit of the current vehicle. After successful verification, the front gate of the current vehicle is opened and the rear gate is closed to guide the current vehicle to leave. The method includes:

[0138] After the vehicle leaves, the control gate will be in the open position.

[0139] In this embodiment, basic information refers to information such as vehicle license plate number, vehicle model, and departure point.

[0140] In this embodiment, the voice announcement reads: "The vehicle has been weighed and can be removed from the scale."

[0141] In this embodiment, the determination of vehicle departure is obtained through the rear camera.

[0142] The beneficial effects of the above technical solution are: after the driver is instructed and weighed, the information is checked. If there are no problems, the vehicle is reminded to leave in time by traffic lights and voice announcements.
