Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dynamic weighing and specifically relates to a high-speed whole-vehicle dynamic weighing system. BACKGROUND

[0002] With the increase of traffic flow and the increasing demand for vehicle over-limit detection, how to accurately measure the total mass of a vehicle under high-speed driving conditions has become an important technical challenge. Although the traditional static weighing method can provide high-precision measurement results, it is inefficient in application scenarios such as highways that require rapid and efficient weighing, and is prone to cause traffic congestion.

[0003] Existing dynamic weighing systems are mainly divided into two categories:

[0004] Low-speed dynamic weighing system: generally applied to scenarios such as highway entrances and exits or over-limit detection stations, adopts whole-vehicle or axle group type weighing equipment, and has a high accuracy level (generally dynamic level 1 or 2), but is only suitable for low-speed passing vehicles and cannot adapt to the application requirements under high-speed driving conditions.

[0005] Medium and high-speed dynamic weighing system: generally applied to scenarios such as non-stop over-limit detection of open roads such as national and provincial highways or bridge protection, adopts partial weighing products such as narrow strip type, quartz type, bending plate type and flat plate type, and has a low accuracy level (generally dynamic level 5 or 10). Although it can adapt to high-speed driving conditions, due to the use of partial weighing method, its accuracy is low and it cannot provide accurate whole-vehicle weight data.

[0006] Therefore, there is an urgent need for a dynamic weighing system that can achieve high-precision whole-vehicle weighing under high-speed driving conditions. SUMMARY

[0007] In view of the deficiencies of the prior art, the application provides a high-speed whole-vehicle dynamic weighing system.

[0008] To solve the above problems, the application provides the following technical scheme: a high-speed whole-vehicle dynamic weighing system, the weighing system is arranged on a driving lane of a target vehicle to be weighed, and is used for weighing the target vehicle passing at high speed on the lane, comprising a plurality of carriers, the plurality of carriers are arranged in an array on the lane, and are used for carrying the wheels of the target vehicle passing at high speed and weighing the weight of the wheels carried on each carrier.

[0009] The total length and total width of the plurality of carriers cover the driving track of all the wheels of the target vehicle, and when the target vehicle passes through the arrangement area of the weighing system at high speed, all the wheels of the target vehicle can be on the carriers at the same time or within a time period.

[0010] Each of the load carriers measures the wheel weight data in real time, and the data processor accumulates each wheel weight data to calculate the total mass of the vehicle.

[0011] Preferably, the multiple load carriers are arranged in parallel or staggered, and the multiple load carriers are arranged in seamless dense arrangement or according to the wheel spacing of the target vehicle.

[0012] Preferably, the width of a single load carrier covers half a lane or covers the entire lane of the road surface.

[0013] Preferably, the load carrier can be one or more combinations of quartz type, curved plate type or flat plate type weighing device.

[0014] Preferably, the data processor adopts a SW2002 type weighing data processor for receiving and processing the weighing data of each load carrier, and calculating the total mass of the vehicle by accumulating the weighing data of each load carrier.

[0015] Preferably, the weighing system further comprises a communication module and a remote monitoring center, and the communication module adopts a SIM800C type GSM or GPRS module for receiving the weighing data from the data processor and transmitting to the remote monitoring center for remote monitoring and data analysis.

[0016] Compared with the prior art, the application provides a high-speed whole vehicle type dynamic weighing system, which has the following beneficial effects:

[0017] The high-speed whole vehicle type dynamic weighing system combines the respective advantages of low-speed whole vehicle weighing products and high-speed partial weighing products, solves the problem that the existing whole vehicle weighing cannot be performed at high speed and cannot be accurately weighed at high speed, significantly improves the weighing accuracy, and thus improves the accuracy of the overall weighing.

[0018] The high-speed whole vehicle type dynamic weighing system can flexibly adjust the layout and size of the load carrier according to actual needs, which can cover half a lane or the entire lane. The length of the load carrier is designed to accommodate one axle or axle group, ensuring that the complete wheel weight is covered during each measurement. This flexibility enables the system to adapt to roads of different widths and axle groups of different lengths, enhancing the versatility and adaptability of the system.

[0019] The high-speed whole vehicle type dynamic weighing system provides multiple types of load carriers for selection, enabling the system to achieve optimal weighing results in different environments and conditions and meet diverse application needs.

[0036] Each carrier 1 measures the wheel weight data carried by it in real time, and accumulates the wheel weight data to calculate the total mass of the vehicle 2 through a data processor.

[0037] When the vehicle 2 passes at high speed, each carrier 1 measures the weight data of the wheels it carries in real time and transmits these data to the data processor.

[0042] In some embodiments, the weighing system further includes a communication module and a remote monitoring center. The communication module uses a SIM800C model GSM or GPRS module to receive the weighing data from the data processor and transmit it to the remote monitoring center for remote monitoring and data analysis.
