Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dynamic weighing and specifically relates to a high-speed axle group type 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] Partial weighing products such as narrow strip type, quartz type, bending plate type and flat plate type are adopted, and the accuracy level is low (generally dynamic 5 or 10 levels). Although it can adapt to high-speed driving conditions, due to the use of partial weighing method, the accuracy is low, and accurate whole vehicle weight data cannot be provided.

[0005] Single axle weighing equipment is used for weighing, and the accuracy level is high (generally dynamic 1 or 2 levels), but it is only suitable for vehicles passing at low speed. The single axle weighing result is easily affected by the unstable state such as jolt and jump of the vehicle during high-speed driving, resulting in low weighing accuracy and reliability.

[0006] Therefore, there is an urgent need for a dynamic weighing system capable of high-precision axle group weighing under high-speed driving conditions. SUMMARY

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

[0008] To solve the above problems, the application provides the following technical scheme: a high-speed axle group type dynamic weighing system, the weighing system is arranged on a target vehicle driving lane 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 perpendicular to the driving direction of the target vehicle on the lane and cover both sides of the lane at the same time, and are used for carrying wheels on two or more vehicle axles of the target vehicle passing at high speed and weighing the weight of the two or more vehicle axles carried on the carriers.

[0009] The total length of the plurality of carriers is not less than the length of the two or more vehicle axles of the target vehicle, and the total width is not less than the width of the outer edges of the wheels of each axle or axle group of the target vehicle. When the target vehicle passes through the weighing system arrangement area at high speed, at least two or more vehicle axles 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 weight data of the target vehicle axle carried by it in real time, and the data processor is used to accumulate and calculate the total mass of the vehicle.

[0011] Preferably, the plurality of load carriers are arranged in an array on the lane, and the load carriers are arranged in parallel or staggered, and the plurality of load carriers are arranged seamlessly and densely or according to the single axle or axle group spacing of the target vehicle.

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

[0013] Preferably, the load carrier can be one or a combination 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 the load carrier, and the data processor is used to accumulate and calculate the total mass of the vehicle.

[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 axle group type dynamic weighing system, which has the following beneficial effects:

[0017] The high-speed axle group type dynamic weighing system weighs two or more axles, effectively reducing the influence of unstable states such as jolting and jumping of the vehicle during driving on the weighing result of a single axle. When the vehicle passes at high speed, the weight information of multiple axles can be accurately obtained, avoiding inaccurate measurement or omission of some axles due to too high speed, and significantly improving the accuracy of the calculation of the total mass of the vehicle.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0031] Please refer to Figures 1-6 The present application provides a new technical solution: a high-speed axle group type dynamic weighing system, the weighing system is arranged on the driving lane 3 of the target vehicle 2 to be weighed, for weighing the target vehicle 2 passing at high speed on the lane 3, characterized in that it comprises a plurality of carriers 1, a plurality of carriers 1 perpendicular to the driving direction of the target vehicle 2 on the lane 3 and covering both sides of the lane 3 at the same time, for carrying the wheels on two or more than two axles of the target vehicle 2 passing at high speed, and weighing the weight of two or more than two axles carried on the carrier 1;

[0032] The total length L of the plurality of carriers 1 is not less than the length of two or more than two axles of the target vehicle 2, and the total width W is not less than the width of the outer edge of the wheels of each axle or axle group of the target vehicle 2, when the target vehicle 2 passes through the weighing system arrangement area at high speed, at least two or more than two axles of the target vehicle 2 can be on the carrier 1 at the same time or in a time period;

[0033] Each carrier 1 measures the weight data of the target vehicle 2 axle carried by it in real time, and accumulates and calculates the total mass of the vehicle 2 through the data processor.

[0034] When in use, when the target vehicle 2 passes at high speed, each carrier 1 can sense the pressure applied by the axle carried by it in real time, and convert it into weight data in the form of electrical signal or the like; the data processor receives the axle weight data from each carrier 1, and accumulates these data through internal algorithm, so as to obtain the total mass of the target vehicle 2. Compared with single axle weighing, simultaneous weighing of two or more than two axles can reduce the influence of unstable driving state of the vehicle 2 (such as bumping, jumping, etc.) on the weighing result of single axle, and improve the accuracy and reliability of weighing. Ensure that when the vehicle 2 passes at high speed, the weight information of multiple axles can be obtained completely and accurately, avoid inaccurate measurement or omission of part of the axles due to fast passing speed of the vehicle 2, so as to more accurately calculate the total mass of the vehicle 2.

[0035] In some embodiments, a plurality of said carriers 1 are arranged in an array on the lane 3, and said carriers 1 are arranged in parallel or staggered, and said carriers 1 are arranged seamlessly and densely or according to the single axle or axle group spacing of said target vehicle 2.

The parallel and staggered arrangement methods and different arrangement methods increase the adaptability of the weighing system to different vehicle types and axle spacings. The system can be flexibly adjusted according to the characteristics of the vehicles 2 on the actual road, improving the versatility and practicality of the system. The probability of accurately measuring the axles by the carriers 1 can be effectively improved, further improving the accuracy and stability of the weighing.

[0037] In some embodiments, the width of a single said carrier 1 covers half of the lane 3 or covers the entire lane 3 of the road surface. When the width of a single carrier 1 covers half of the lane 3, it can cover the entire lane 3 by reasonably combining a plurality of carriers 1 for the case that the lane 3 is wide and the vehicle 2 driving track is diverse; when the width of a single carrier 1 covers the entire lane 3, the vehicle 2 passing through the lane 3 can be directly weighed without the need for splicing and combining a plurality of carriers 1.

[0041] The application also provides a weighing method of the high-speed axle group type dynamic weighing system, comprising the following steps:

[0042] The plurality of carriers 1 are arranged in an array on the lane 3, covering two or more axles of the target vehicle 2;
