Description

Technical Field

[0001] The invention relates to the technical field of large-piece transportation, and in particular to a large-piece transportation weighing method. Background Art

[0002] In the large-scale transportation industry, vehicle weight data is extremely important for transportation safety, road and bridge load assessment, and compliance transportation supervision. At present, the existing weighing method is mainly to directly weigh the large-scale transportation vehicle as a whole through specific weighing equipment to obtain the total weight data of the vehicle. For example, in the common weighing system, when the vehicle drives onto the weighing scale, the weighing sensor senses the gravity of the vehicle and then calculates the total weight value of the vehicle.

[0003] However, this traditional weighing method has obvious limitations. Simply obtaining the total weight data of the vehicle is far from enough for the comprehensive evaluation and precise management of large-scale transport vehicles. In the actual transportation process, the weight distribution of the vehicle is also crucial. Different types of large goods are loaded in different positions on the vehicle, which will lead to huge differences in the weight borne by each axle and each part of the vehicle. For example, some overlong and overweight large mechanical equipment may have a center of gravity biased to one side or the rear of the vehicle. If this weight distribution information cannot be accurately grasped, the uneven force on the vehicle during transportation may cause safety accidents such as excessive tire wear, frame deformation, and even vehicle loss of control.

[0004] Moreover, the number of axles of a vehicle is also a key parameter. The number of axles is not only related to the load-bearing capacity of the vehicle, but also has important reference value in the implementation of road tolls and bridge weight limit regulations. However, the existing direct weighing process cannot obtain the number of axles of the vehicle, and requires additional manual inspection and recording, which not only increases labor costs, but is also prone to human errors and untimely and inaccurate data recording.

[0005] With the continuous development of the large-scale transportation industry, the types and shapes of large items being transported are becoming increasingly diverse, and the requirements for accurate management of transportation vehicles are becoming increasingly higher. The existing weighing method is difficult to meet the needs of obtaining important data such as vehicle weight distribution and number of axles, which limits the further development of the industry in terms of transportation safety, transportation efficiency improvement, and transportation cost optimization. Therefore, there is an urgent need for a new technical solution that can simultaneously obtain multi-dimensional data information such as vehicle weight distribution and number of axles during the weighing process or through operations related to weighing, so as to fill the gaps in existing technologies and provide strong technical support for the healthy and stable development of the large-scale transportation industry. Summary of the invention

[0006] The purpose of the present invention is to provide a large-piece transport weighing method, which can realize weighing and determination of the number of axles at the same time.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions: A method for weighing large pieces of transport, comprising the steps of: A1: Obtain weight data and weighing count data of a first weighing body, and define the weight data of the first weighing body as first weight data, wherein the weighing count data includes the time of weight recording and the number of weight recordings, and obtain the number of axles of the vehicle according to the number of weight recordings; A2: Obtain weighing data of a second scale, and define the weight data of the second scale as second weight data, wherein the second weighing data includes the weight recorded and the time of the weight record, and the weight recorded for the last time in the vehicle weighing process is recorded as the total weight information of the vehicle; A3: Calculate the speed of each axle of the vehicle during weighing according to the first weight data, the number of axles of the vehicle, the second weight data and the positional relationship between the first scale and the second scale, and calculate the distance information between adjacent axles according to the interval time between each axle passing through the first scale and the second scale; A4: Calculate the weight distribution information of each axis through the distance information between adjacent axes and the first weight data.

[0008] In a preferred embodiment, the first scale is tilted relative to the second scale, and step A4 specifically includes calculating the weight distribution information of each axis and the weight distribution information at both ends of the axis through the distance information between adjacent axes and the first weight data information.

[0009] In a preferred embodiment, a plurality of pressure sensors are provided between the first scale and the second scale for acquiring pressure information, and A3 specifically includes: determining the position of the wheels of the vehicle in the width direction of the vehicle according to the pressure information, retrieving the data corresponding to the position, obtaining the actual distance traveled by each wheel from the first scale to the second scale, and calculating the speed of each wheel of the vehicle during weighing according to the actual distance traveled by each wheel from the first scale to the second scale, the first weight data, the weighing count data, the number of axles of the vehicle, the second weight data and the positional relationship between the first scale and the second scale, and calculating the distance information between adjacent axles according to the interval time between each wheel passing through the first scale and the second scale.

[0010] In a preferred embodiment, the plurality of pressure sensors are arranged in a straight line.

[0011] In a preferred embodiment, the method for calculating the distance information between adjacent axles is: select the wheel on a certain side as the calculation object, calculate the interval distance between adjacent wheels on this side, and record it as the distance between the corresponding adjacent axles, the interval distance between adjacent wheels = (the time when the rear wheel reaches the first scale body - the time when the front wheel reaches the second scale body) * the speed of the front wheel + (the time when the rear wheel reaches the second scale body - the time when the rear wheel reaches the first scale body) * the speed of the rear wheel, wherein the speed of the front wheel = the actual distance moved by the front wheel between the first scale body and the second scale body / (the time when the front wheel reaches the second scale body - the time when the front wheel reaches the first scale body), the speed of the rear wheel = the actual distance moved by the rear wheel between the first scale body and the second scale body / (the time when the rear wheel reaches the second scale body - the time when the rear wheel reaches the first scale body).

[0012] In a preferred embodiment, the weight information of the axle is the sum of the weighed weights of two wheels of the corresponding axle.

[0013] In a preferred embodiment, the number of the pressure sensors is 8 and they are arranged in two groups.

[0014] In a preferred embodiment, the shortest distance between the first scale and the second scale in a length direction parallel to the second scale is 30-40 cm, and the longest distance is 50-60 cm.

[0015] In a preferred embodiment, the angle α between the first scale body and the second scale body is set to 10-20 degrees.

[0016] In a preferred embodiment, it also includes A5: adding the first weight data and comparing the addition result with the second weighing data. When the difference between the two is within a preset range, the weighing is valid. When the difference between the two is outside the preset range, the data of the first weighing is invalid.

[0017] Compared with the prior art, the present invention provides a large-piece transport weighing method, which has the following advantages: In terms of axle number determination, this method can accurately determine the axle number of the vehicle through precise analysis of the weighing and counting data of the first scale. Traditional weighing methods often require additional manual inspection and recording of axle numbers, which is not only labor-intensive but also prone to errors. This method cleverly combines axle number information with the weighing process to achieve automated axle number acquisition, greatly improving the accuracy and efficiency of axle number determination, effectively avoiding errors caused by human factors, and providing accurate and reliable basic data for subsequent transportation planning, road tolls, and bridge load assessment.

[0018] Secondly, regarding the measurement of the total weight of the vehicle, this weighing method uses the weighing data of the second scale to accurately determine the last weight record in the vehicle weighing process as the total weight information of the vehicle. This method ensures the timeliness and accuracy of the acquisition of total weight data. Compared with traditional weighing, which can only obtain the total weight but lacks data integration and precise positioning, this method enables the total weight data to be used more effectively in the entire transportation data system. For example, it can provide clear and unquestionable basis for judging whether the vehicle is overweight to meet the requirements of road transportation regulations.

[0019] Furthermore, in acquiring the axle distance information, the present invention successfully calculates the speed of each axle of the vehicle during weighing based on the first weight data, the number of axles information, the second weight data, and the positional relationship between the first scale and the second scale, and then obtains the distance information between adjacent axles based on the interval time when the axle passes through the two scales. In previous weighing technologies, obtaining axle distance information often requires a large number of complex sensor layouts or cumbersome manual measurements, which are costly and inconvenient to operate. However, this method can easily achieve the determination of axle distance with the help of the collaborative calculation of two scales and related data, greatly reducing the difficulty and cost of technical implementation, and providing key data support for structural analysis of large-scale transport vehicles, driving stability research, etc.

[0020] Finally, in terms of the calculation of axle weight distribution information, the weight distribution of each axle can be accurately calculated through the distance information between adjacent axles and the first weight data that have been obtained. This is of great significance for large-scale transportation, because the weight distribution of different axles is directly related to important issues such as vehicle driving safety, tire wear, and frame force balance. In the past, the method of requiring many scales to determine axle weight distribution not only required huge equipment investment, but also complicated data integration and processing. This method achieves the acquisition of axle weight distribution information in a simple and efficient way, allowing transportation companies to more accurately allocate vehicles, optimize cargo loading, and plan transportation routes, thereby effectively improving transportation safety, reducing transportation costs, and extending vehicle service life.

[0021] In summary, this large-scale transport weighing method has achieved significant breakthroughs in many key technical indicators such as axle number judgment, total weight measurement, axle distance acquisition, and axle weight distribution calculation with its innovative design and efficient data processing logic. Compared with existing technologies, it has demonstrated incomparable advantages in economy, convenience, and data accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0028] During the execution of a large-piece transportation method of the present embodiment, the vehicle passes the first scale and then reaches the scale, during which the weighing process is realized.

[0029] like Figures 1 to 3 As shown, a method for weighing large-piece transportation includes the following steps: A1: Obtain weight data and weighing count data of a first weighing body 1, and define the weight data of the first weighing body 1 as first weight data, wherein the weighing count data includes the time of weight recording and the number of weight recordings, and obtain the number of axles of the vehicle according to the number of weight recordings; A2: Obtain the weighing data of the second weighing body 2, and define the weight data of the second weighing body 2 as the second weight data, the second weighing data includes the weight recorded and the time of the weight record, and the weight recorded for the last time in the vehicle weighing process is recorded as the total weight information of the vehicle; A3: Calculate the speed of each axle of the vehicle during weighing according to the first weight data, the number of axles of the vehicle, the second weight data and the positional relationship between the first scale body 1 and the second scale body 2, and calculate the distance information between adjacent axles according to the interval time between each axle passing through the first scale body 1 and the second scale body 2; A4: Calculate the weight distribution information of each axis through the distance information between adjacent axes and the first weight data.

[0030] This embodiment provides a large-piece transport weighing method, which has the following advantages: In terms of axle number determination, this method can accurately determine the axle number of the vehicle through accurate analysis of the weighing and counting data of the first scale 1. Traditional weighing methods often require additional manual inspection and recording of axle numbers, which is not only labor-intensive but also prone to errors. This method cleverly combines axle number information with the weighing process to achieve automated axle number acquisition, greatly improving the accuracy and efficiency of axle number determination, effectively avoiding errors caused by human factors, and providing accurate and reliable basic data for subsequent transportation planning, road tolls, and bridge load assessment.

[0031] Secondly, regarding the measurement of the total weight of the vehicle, the weighing method uses the weighing data of the second scale 2 to accurately determine the last weight record in the vehicle weighing process as the total weight information of the vehicle. This method ensures the timeliness and accuracy of the acquisition of the total weight data. Compared with the traditional weighing that can only obtain the total weight but lacks data integration and precise positioning, the method enables the total weight data to be used more effectively in the entire transportation data system. For example, it can provide a clear and unquestionable basis for judging whether the vehicle is overweight to meet the requirements of road transportation regulations.

[0032] Furthermore, in acquiring the axle distance information, this method successfully calculates the speed of each axle of the vehicle during weighing based on the first weight data, the number of axles, the second weight data, and the positional relationship between the first scale 1 and the second scale 2, and then obtains the distance information between adjacent axles based on the interval time between the axles passing through the two scales. In previous weighing technologies, obtaining axle distance information often requires a large number of complex sensor layouts or cumbersome manual measurements, which are costly and inconvenient to operate. However, this method can easily achieve the determination of axle distance with the help of the collaborative calculation of two scales and related data, greatly reducing the difficulty and cost of technical implementation, and providing key data support for the structural analysis and driving stability research of large-scale transport vehicles.

[0033] Finally, in terms of the calculation of axle weight distribution information, the weight distribution of each axle can be accurately calculated through the distance information between adjacent axles and the first weight data that have been obtained. This is of great significance for large-scale transportation, because the weight distribution of different axles is directly related to important issues such as vehicle driving safety, tire wear, and frame force balance. In the past, the method of requiring many scales to determine axle weight distribution not only required huge equipment investment, but also complicated data integration and processing. This method achieves the acquisition of axle weight distribution information in a simple and efficient way, allowing transportation companies to more accurately allocate vehicles, optimize cargo loading, and plan transportation routes, thereby effectively improving transportation safety, reducing transportation costs, and extending vehicle service life.

[0034] In summary, this large-scale transport weighing method has achieved significant breakthroughs in many key technical indicators such as axle number judgment, total weight measurement, axle distance acquisition, and axle weight distribution calculation with its innovative design and efficient data processing logic. Compared with existing technologies, it has demonstrated incomparable advantages in economy, convenience, and data accuracy.

[0035] In order to further obtain richer data, the first scale 1 is tilted relative to the second scale 2 . At this time, the number of axles of the vehicle is equal to half of the number of weighing times recorded by the first scale 1 .

[0036] The step A4 specifically includes calculating the weight distribution information of each axle and the weight distribution information at both ends of the axle through the distance information between adjacent axles and the first weight data information. The weight distribution information mainly refers to the weight distribution at both ends of the axle. Under normal circumstances, the weight at both ends of the axle should be distributed equally. If it is not equal, it means that there is a weight bias, so that more abundant vehicle information can be obtained.

[0037] In order to accurately determine the actual distance traveled by the wheel when the first weighing body 1 is tilted, a plurality of pressure sensors 3 are provided between the first weighing body 1 and the second weighing body 2 for obtaining pressure information, and the A3 specifically includes: determining the position of the wheel of the vehicle in the width direction of the vehicle according to the pressure information, retrieving the data corresponding to the position, obtaining the actual distance traveled by each wheel from the first weighing body 1 to the second weighing body 2, and calculating the speed of each wheel of the vehicle during weighing according to the actual distance traveled by each wheel from the first weighing body 1 to the second weighing body 2, the first weight data, the weighing count data, the number of axles of the vehicle, the second weight data and the positional relationship between the first weighing body 1 and the second weighing body 2, and calculating the distance information between adjacent axles according to the interval time between each wheel passing through the first weighing body 1 and the second weighing body 2.

[0038] The principle for determining the actual distance traveled by each wheel from the first scale body 1 to the second scale body 2 is as follows: a plurality of pressure sensors 3 are provided, each corresponding to a specific position. When the wheel passes through the pressure sensor 3, the position of the wheel is the position of the pressure sensor 3. Thus, the path passed by the wheel can be determined through the position corresponding to the pressure sensor 3, thereby realizing the determination of the actual distance traveled by the wheel from the first scale body 1 to the second scale body 2.

[0039] Specifically, the plurality of pressure sensors 3 are arranged in a straight line to achieve full coverage of the path.

[0040] Further, the distance information between adjacent axles is calculated as follows: a wheel on one side is selected as the calculation object, the interval between adjacent wheels on the side is calculated, and the interval between adjacent wheels is recorded as the distance between the corresponding adjacent axles, and the interval between adjacent wheels = (the time when the rear wheel reaches the first scale body 1-the time when the front wheel reaches the second scale body 2) * the speed of the front wheel + (the time when the rear wheel reaches the second scale body 2-the time when the rear wheel reaches the first scale body 1) * the speed of the rear wheel, wherein the speed of the front wheel = the actual distance moved by the front wheel between the first scale body 1 and the second scale body 2 / (the time when the front wheel reaches the second scale body 2-the time when the front wheel reaches the first scale body 1), and the speed of the rear wheel = the actual distance moved by the rear wheel between the first scale body 1 and the second scale body 2 / (the time when the rear wheel reaches the second scale body 2-the time when the rear wheel reaches the first scale body 1). By calculating in this way, the travel distance of the front wheel and the formal distance of the rear wheel are calculated separately, which is conducive to reducing the error of the vehicle speed change, thereby making the result more accurate.

[0041] Under the above setting conditions, the speed of each axle when weighing refers to the specific speed of the corresponding wheels on both sides.

[0042] Furthermore, the weight information of the axle is the sum of the weighed weights of the two wheels corresponding to the axle.

[0043] Furthermore, the number of the pressure sensors 3 is 8 and they are arranged in two groups.

[0044] Further, the shortest distance between the first scale body 1 and the second scale body 2 in the length direction parallel to the second scale body 2 is 30-40 cm, and the longest distance is 50-60 cm, and the angle α between the first scale body 1 and the second scale body 2 is set to 10-20 degrees. By setting such distance and angle, it is conducive to achieving accurate information acquisition.

[0045] A method for weighing large-piece transportation in this embodiment further includes A5: adding the first weight data and comparing the addition result with the second weighing data. When the difference between the two is within a preset range, the weighing is valid. When the difference between the two is outside the preset range, it indicates that there are interferences from other factors when passing through the first scale 1, such as the influence of the shaking of the vehicle itself. At this time, the data of the first scale 1 is invalid. In this state, a re-inspection can be performed, or the invalid information can be recorded as a record.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. In the absence of further restrictions, the elements defined by the sentence "include..." or "comprise..." do not exclude the existence of other elements in the process, method, article or terminal device including the elements. In addition, in this article, "greater than", "less than", "exceed" and the like are understood to exclude the number itself; "above", "below", "within" and the like are understood to include the number itself.
