Problems solved by technology

However, although the hardware method of increasing the weighing distance and improving the accuracy can achieve the goal, the cost is extremely high. Every time the weighing adaptation speed is doubled, the cost needs to be doubled. The structure and workflow are very complex
In addition, although the software method of improving the accuracy through software can also achieve the goal, the software fitting needs to collect vibration signals of at least 2 / 3 cycles, so its effect on improving the adaptability of weighing speed is limited
At the same time, the strip sensor is different from the axle load type and wheel load type sensor, which cannot collect a continuous signal, so it cannot perform better software data fitting

Embodiment Construction

[0023] Dynamic vehicle weighing is the measurement of the gross and / or partial weight of a moving vehicle by measuring and analyzing tire dynamic forces. A weighing device typically includes a set of sensors and electronics including software to measure dynamic tire forces, the vehicle's wheel weight, axle weight, and / or gross weight. Dynamic vehicle weighing can usually be applied in multiple scenarios such as vehicle weighing and high-speed overrun management.

[0024] figure 1 An exemplary schematic diagram showing plate weighing commonly used in existing weighing devices. Such as figure 1 As shown, a square plate 102 is arranged in the groove on the driveway 101 and the plate is flush with the driveway, and four load cells 103 are arranged at the bottom of the four corners of the plate. The square plate 102 and the load cell 103 at the bottom form a plate weighing device. Among them, the four load cells can be connected to the electronic instrument 105 through wireless...

Abstract

The invention relates to a dynamic weighing method and a dynamic weighing device for a vehicle. The dynamic weighing method comprises the following steps: acquiring a weighing signal which is applied to a road surface plate in the advancing process of the vehicle and is related to the weight of the vehicle; obtaining a vibration signal related to vibration of the pavement plate caused by the vehicle in the advancing process; and determining the weight of the vehicle according to the weighing signal and the vibration signal. The weighing signal and the vibration signal are fused, errors caused by vibration in the weighing process are reduced, and the weighing precision is improved.

Description

technical field [0001] The present disclosure relates generally to the field of weighing technology. Specifically, the present disclosure relates to a dynamic weighing method and a dynamic weighing device for a vehicle. Background technique [0002] Dynamic weighing technology refers to the technology of weighing the vehicle while the vehicle is moving. The commonly used weighing forms include axle load type, wheel weight type and incomplete weighing type of strip sensor. However, vibrations are unavoidable when the vehicle is running. Vehicle vibration is an important source of dynamic vehicle weighing errors and is related to vehicle speed. As a result, the above weighing methods are usually accurate when the vehicle running speed is below 15km / h, and it is difficult to accurately weigh after it is greater than 15km / h. [0003] To solve the vibration problem of dynamic weighing, there are usually two methods of hardware and software. The hardware method is to increase t...
