Description

Technical Field

[0001] The present application relates to the technical field of non-stop weighing, and in particular to a calibration method, system and equipment suitable for a weighing system of a large-scale transport vehicle. Background Art

[0002] With the development of economy and the advancement of infrastructure construction, the demand for large-scale transportation is increasing. Large-scale transportation usually involves the transportation of overweight, overlong, overwide or overhigh goods, such as large machinery and equipment, wind turbine blades, prefabricated components, etc. In order to ensure the safety and legality of these special goods during transportation, the weight of the transport vehicle and its cargo must be accurately measured. However, the existing dynamic vehicle weighing system (WIM, Weigh-in-Motion) is mainly designed for ordinary vehicles, and its verification standards are also based on standard vehicle models.

[0003] In practical applications, due to the complex structure, uneven load distribution and large size of large-scale transport vehicles, traditional calibration methods are difficult to directly apply to the weighing system of such special vehicles. In addition, large-scale transport vehicles are often not universal, and the design and specifications of each model may be significantly different, which further increases the difficulty of calibration. More importantly, due to the lack of calibration standard vehicles that match the load and size of large-scale transport vehicles in reality, it is difficult to find a suitable transfer standard to ensure the accuracy of the calibration results when calibrating the weighing system of large-scale transport vehicles.

[0004] In order to solve the above problems, it is necessary to develop a calibration method specifically for the weighing system of large-scale transport vehicles. This method not only needs to consider how to use existing resources (such as standard vehicles) to simulate the actual working conditions of large-scale transportation, but also needs to ensure that the calibration process can effectively evaluate the performance of the weighing sensor and that the final result has a high degree of credibility. Through this method, the reliability of the weighing data of large-scale transport vehicles can be improved, thereby better ensuring road safety and promoting the healthy development of the logistics industry.

Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods.

[0045] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0046] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0047] The embodiment of the present application provides a calibration method applicable to the weighing system of large-scale transport vehicles, in which for one or more standard vehicles participating in the calibration test, the agreed true value is first obtained (the agreed true value should actually include the agreed true value of the axle weight of each axle), and the vehicle is driven through the weighing system to be calibrated at a certain speed (three levels or more speed conditions such as low speed, medium speed, and high speed), and the axle weight of each axle is obtained by driving through each axle of the test vehicle. When each error between the axle weight obtained by the test and the agreed true value is within the maximum allowable error, it can be considered that the weighing system to be calibrated meets the use requirements or standards after calibration; otherwise, it does not meet the requirements.

[0048] Please refer to Figure 1 In order to solve the problem that the existing calibration method lacks a calibration standard vehicle that is compatible with the load and size of a large-piece transport vehicle, which makes it difficult to find a suitable transfer standard to ensure the accuracy of the calibration result when calibrating the weighing system, an embodiment of the present application provides a calibration method for a large-piece transport vehicle weighing system, which is used to calibrate a weighing system to be calibrated, and the weighing system to be calibrated is used to weigh the large-piece transport vehicle. The calibration method includes the following steps:

[0049] Step S101: provide at least one standard vehicle, wherein the standard vehicle comprises at least two axles.

[0050] In some embodiments, standard vehicles that meet specific requirements are selected, and these vehicles should have at least two axles. The selection of standard vehicles should take into account factors such as their structural stability, wheelbase length, and axle weight distribution to simulate the actual situation of large-scale transport vehicles as much as possible. In addition, the standard vehicles are well maintained to ensure that they will not affect the accuracy of the test results due to their own faults during the calibration process.

[0051] Step S102: Obtain the agreed true value of the axle weight of each axle of the standard vehicle, wherein the agreed true value of the axle weight of each axle is between a maximum axle weight threshold and a minimum axle weight threshold.

[0052] In some embodiments, the maximum axle weight threshold and the minimum axle weight threshold are 20T and 2T respectively.

[0053] In some embodiments, a static weighing device or other high-precision measuring tool is used to accurately measure the agreed true value of each axle of a standard vehicle. To ensure the validity of the data, the weight of the same axle should be measured multiple times at different times and locations, and the average value is taken as the agreed true value of the axle weight of the axle. At the same time, the maximum axle weight threshold is set to 20 tons and the minimum axle weight threshold is set to 2 tons to cover the axle weight range of most large-scale transport vehicles.

[0054] Step S103: performing at least one comprehensive test process on the weighing system to be inspected based on the standard vehicle.

[0055] For example, in some embodiments, a standard vehicle is passed through the weighing system to be tested at a constant speed, and the axle weight measurement of each axle is recorded as it passes through the system. During the test, the vehicle speed needs to be kept stable to avoid measurement errors caused by speed changes. This step may need to be repeated multiple times to verify the consistency of the weighing system performance under different conditions.

[0056] In some embodiments, the comprehensive test process includes driving the standard vehicle through the weighing system to be tested at least once at different test speeds and / or from different positions to obtain the axle weight measurement value of each axle passing through the weighing system to be tested; judging whether the error between each axle weight measurement value and the corresponding axle weight agreed true value is no greater than an error threshold; if so, the weighing system to be tested of the comprehensive test process is deemed qualified; if not, the weighing system to be tested of the comprehensive test process is deemed unqualified.

[0057] Step S104: If the weighing system to be inspected is qualified in each comprehensive test process, it is determined that the weighing system to be inspected is qualified.

[0058] In some embodiments, after completing all the predetermined comprehensive test processes, if the measurement results of the weighing system to be verified in each test meet the preset qualification standards (i.e., the error between each axle weight measurement value and the corresponding axle weight agreed true value does not exceed the error threshold), then the weighing system can be considered to have passed the verification. Otherwise, it is necessary to further analyze the reasons for the failure and take corresponding measures to adjust or repair it.

[0059] Please refer to Figure 2 , wherein the comprehensive test process in step S103 comprises the following steps:

[0060] Step S201: driving the standard vehicle through the weighing system to be tested at the same test speed or the same position, and obtaining the axle weight measurement value of each axle passing through the weighing system to be tested.

[0061] In some embodiments, first, a reasonable test vehicle speed is selected, which is usually recommended to be around 10km / h, which is a common driving speed for large-scale transport vehicles. The test vehicle speed should be kept constant to reduce the measurement error caused by speed changes. A speed monitoring device (such as a radar speedometer) can be set to ensure that the vehicle maintains a constant speed throughout the test. Before the test, ensure that the standard vehicle is in good condition, the tire pressure is normal, and the vehicle has no obvious damage or abnormality. The standard vehicle should be driven smoothly along the predetermined route, avoiding sudden acceleration, sudden braking or sudden turning to reduce unnecessary interference. At the same time, ensure that the weighing system to be verified has been properly installed and calibrated, and the signal transmission line of the sensor is connected normally without looseness or damage. The sensor should be in working condition and ready to receive and record data. When the standard vehicle passes through the weighing system to be verified at a constant speed, the sensor will automatically record the axle weight data of each axle when it passes. These data should be transmitted to the data acquisition system in real time and saved for subsequent analysis. The data acquisition system should have high precision and high sampling rate to ensure the accuracy and integrity of the data. In addition, the interference of external environmental factors such as wind speed and road conditions should be minimized during the test. You can choose to conduct the test under good weather and smooth road conditions to ensure the reliability of the test results.

[0062] Step S202, determine whether the error between each axle weight measurement value and the corresponding axle weight agreed true value is not greater than the error threshold. If so, the weighing system to be tested in the comprehensive test process described this time is deemed qualified; if not, the weighing system to be tested in the comprehensive test process described this time is deemed unqualified.

[0063] In some embodiments, the axle weight measurement data of each axle is extracted from the data acquisition system and compared with the axle weight agreed true value of the axle. The error between the axle weight measurement value of each axle and the axle weight agreed true value is calculated using the formula: According to the actual application requirements and industry standards, set a reasonable error threshold. For example, the error threshold can be set to 5% or 100kg (the specific value can be determined according to the accuracy requirements of the sensor and the application scenario). The error threshold should not only ensure the accuracy of the measurement, but also have a certain fault tolerance. Check whether the error of each axis is not greater than the set error threshold one by one. If the errors of all axes meet the conditions, the weighing system to be tested in this comprehensive test process is considered qualified. If the error of any axis exceeds the error threshold, the weighing system to be tested in this comprehensive test process is considered unqualified.

[0064] In the above-mentioned verification method applicable to the weighing system of large-piece transport vehicles, as a preferred solution, after performing at least one comprehensive test process on the weighing system to be verified based on the standard vehicle, it also includes:

[0065] Step S105: If the proportion of qualified times in at least one comprehensive test process is not less than the qualified judgment threshold, the weighing system to be calibrated is deemed to be qualified; the proportion of qualified times is the proportion of qualified times in the total number of at least one comprehensive test process.

[0066] In some embodiments, after multiple tests, the ratio of the number of qualified tests to the total number of tests is calculated. If this ratio is not lower than a pre-set qualified judgment threshold (e.g., 95%), the sensor is considered to have performed well overall and can be considered qualified. This mechanism allows a certain degree of fault tolerance while ensuring the overall detection quality.
