[0002] Vehicle load measurement refers to the process of measuring the weight of goods or people carried by a vehicle (a vehicle is a general term for land wheeled, chained and tracked transport vehicles). Currently, there are several main methods for measuring vehicle load, but they all have some difficult to solve problems:

[0045] In order to solve the problems of the prior art, the present embodiment provides a non-contact measurement method for the load of a vehicle. The method based on the present embodiment can effectively solve the problems of low detection accuracy, cumbersome installation and deployment, short service life, high maintenance cost, etc. of the existing methods, and further expand the scope of application for different types of vehicles. In specific application, the present embodiment first obtains the degree of compression of the suspension device between the frame and the axle, the frame bears the load of the vehicle, and the frame is set on the axle. Then, based on the degree of compression, the distance change information between the frame and the axle is obtained. Then, based on the distance change information, the change in the load of the vehicle is determined to achieve the measurement of the load of the vehicle. The present embodiment realizes non-contact measurement of the load of the vehicle, which greatly extends the service life while ensuring the measurement accuracy, is quick to install and deploy, and has low maintenance costs.

[0046] The non-contact measurement method of the vehicle load of this embodiment can be applied to a vehicle system or a terminal, and the terminal can be a vehicle terminal or an external terminal connected to the vehicle terminal, such as a user's mobile phone terminal. Figure 1 As shown in , the non-contact measurement method of the load capacity of a carrier of this embodiment includes the following steps:

[0047] Step S100, obtaining the compression degree of the suspension device between the frame and the axle, the frame bearing the load of the vehicle, and the frame being arranged on the axle.

[0048] The non-contact measurement method of the vehicle load in this embodiment is mainly used to measure the load on the frame. Figure 2As shown, a suspension device is arranged between the frame and the axle, and the frame is arranged on the axle, and the frame bears the load (i.e., the load) of the vehicle. The sensor is fixed on the frame and is used to measure the deformation of the suspension device. In this embodiment, the frame is a frame-type structure spanning the front and rear axles of the vehicle, commonly known as a beam, and is the base of the car. It is generally composed of two longitudinal beams and several cross beams, and is supported on the wheels via a suspension device, a front axle, and a rear axle. The frame must have sufficient strength and rigidity to withstand the load of the car and the impact from the wheels. The function of the frame is to support and connect the various assemblies of the vehicle, so that each assembly maintains a relatively correct position, and withstands various loads inside and outside the car. The axle (also called the axle) is connected to the frame (or load-bearing body) through a suspension device, and wheels are installed at both ends. The function of the axle is to bear the load of the vehicle and maintain the normal driving of the vehicle on the road. The suspension device (also called suspension) is a general term for all force transmission connection devices between the vehicle frame (or load-bearing body) and the axle. Its function is to transmit the force and torque acting between the wheel and the frame, and to buffer the impact force transmitted to the frame or body by the uneven road surface, and reduce the vibration caused thereby. The suspension device is provided with a deformable member, including any one of a spring, a spring and an air suspension assembly, so the suspension device will show different degrees of compression according to the change of the load of the frame. The sensor refers to a device that can measure the distance from itself to the surface it points to. The sensor is fixed on the frame and measures the distance from the frame to the suspension device or from the frame to the axle, thereby reflecting the degree of compression of the suspension device. The sensor of this embodiment realizes the distance measurement in a non-contact manner. The optional methods include: laser distance measurement, ultrasonic distance measurement or eddy current distance measurement, etc. In actual application, any one of laser distance measurement, ultrasonic distance measurement and eddy current distance measurement can be selected, and this embodiment does not limit this.

[0049] In one implementation, this embodiment includes the following steps when determining the compression degree of the suspension device:

[0050] Step S101, determining a deformable component in the suspension device;

[0051] Step S102: detecting the deformation of the deformable component based on a sensor fixed on the vehicle frame to obtain an analog signal;

[0052] Step S103: performing analog-to-digital conversion processing on the analog signal through a preset controller to obtain the compression degree of the suspension device.

[0053] This embodiment measures the compression degree of the suspension device by a non-contact method, wherein the suspension device includes a deformable component, and the deformable component includes any one of a spring, a spring, and an air suspension component. Regardless of which deformable component is used, the suspension device connects the frame and the axle with a compressible structure. Figure 3As shown in , the sensor is fixed on the vehicle frame and points in the direction of the axle. The surface pointed by the sensor may be the axle or a deformable component (such as a spring) in the suspension device. Since the suspension device is connected to the axle, the deformable component of the suspension device is regarded as an extension of the axle.

[0054] In practical applications, combined with Figure 4 As shown, when the load on the frame changes, the compression degree of the suspension device will change, that is, the distance between the frame and the axle will change, that is, Figure 4 D in changes, and the sensor can detect the deformation of the suspension device at this time, and the output signal of the sensor changes immediately. The sensor outputs an analog signal (such as voltage). The analog signal is then input into a preset controller, and the controller performs analog-to-digital conversion on the analog signal to obtain a digital signal, thereby obtaining a specific value, which reflects the degree of compression of the suspension device.

[0055] Step S200: Based on the compression degree, obtain distance change information between the frame and the axle.

[0056] Since the suspension device connects the frame and the axle, when the load of the vehicle changes, the suspension device presents different compression degrees: when the load of the vehicle increases, the compression degree of the suspension device increases, and the distance between the frame and the axle decreases; when the load of the vehicle decreases, the compression degree of the suspension device decreases, and the distance between the frame and the axle increases. Therefore, the change in the compression degree of the suspension device in this embodiment reflects the distance change information between the frame and the axle. The distance change information can be stored in the controller for processing and analysis.

[0057] Step S300: Based on the distance change information, determine the change in the vehicle load capacity to achieve measurement of the vehicle load capacity.

[0058] Since the distance change information between the frame and the axle in this embodiment is caused by the change in the vehicle load, the controller of this embodiment can analyze the change in the vehicle load based on the detected distance change information, thereby realizing non-contact measurement of the vehicle load.

[0059] In one implementation, when determining the change in the load capacity of the vehicle, this embodiment includes the following steps:

[0060] Step S301, based on Hooke's law, obtain a linear function relationship between the elastic force change and the compression change;

[0061] Step S302, substituting the distance change information into the linear function relationship to calculate and obtain weight change information;

[0062] Step S303: Obtain the weight of the frame, and obtain the change in the load capacity of the vehicle based on the weight change information and the weight of the frame.

[0063] According to Hooke's law, for an ideal spring, within the elastic limit, the change in the spring's elastic force ΔF and the change in the spring's length Δx form a linear function relationship, that is: ΔF = kΔx, denoted as f(Δx) = ΔF, where k is the elastic coefficient of the spring. The k value is the input condition of the system and is a known condition. For different types of suspension devices, the change in the elastic force ΔF (i.e., the weight change information of the vehicle load and the weight of the frame) and the change in the degree of compression of the suspension device Δx (i.e., the degree of compression or the distance change information D between the frame and the axle) will follow the above linear function relationship f(Δx). Therefore, after detecting and obtaining the distance change information between the frame and the axle, this embodiment can substitute the distance change information between the frame and the axle into the linear function relationship to calculate ΔF, thereby calculating ΔF, and obtaining the weight change information of the vehicle load and the weight of the frame. Then, the weight change information is subtracted from the weight change information to obtain the change in the vehicle load, and at this time, the non-contact measurement of the vehicle load is achieved. After the change in the vehicle load weight is calculated, it can be stored in the controller, and the controller transmits the change in the vehicle load weight to an execution device, such as a host computer.

[0064] In summary, the present embodiment can first obtain the degree of compression of the suspension device between the frame and the axle, the frame bears the load of the vehicle, and the frame is arranged on the axle. Then, based on the degree of compression, the distance change information between the frame and the axle is obtained. Then, based on the distance change information, the change amount of the load of the vehicle is determined to achieve the measurement of the load of the vehicle. The present embodiment effectively solves the problems of low detection accuracy, cumbersome installation and deployment, short service life, high maintenance cost, etc. of the existing method, and further expands the scope of application for different types of vehicles. In addition, the sensor of the present embodiment has no contact with the measured surface (i.e., the axle), so it is not easy to wear or be damaged, has a long service life, and has a low maintenance cost. The sensor only needs to be able to measure the distance change information between the frame and the axle, so the installation of the sensor is very simple, and the sensor is not restricted in the way of realizing distance measurement, which can be selected according to the working environment and cost requirements. There are many optional methods such as ultrasonic distance measurement, laser distance measurement, eddy current distance measurement, etc., which have a wide range of applications. In addition, the distance change information between the frame and the axle measured in this embodiment is only related to the load of the vehicle, there are no interference factors, and the measurement result is accurate in theory. Of course, in other implementations, the linear function relationship of the suspension device can be accurately measured by deploying a machine learning method on the controller side, thereby further improving the measurement accuracy of the vehicle load. The vehicle load measurement method designed in this embodiment does not limit the type of vehicle, the implementation method of the suspension device, etc. It only needs to measure the distance change information between the frame and the axle to calculate the vehicle load, and has a wide range of applications.

Furthermore, the system of this embodiment includes: a frame, a suspension device, an axle, and a sensor, wherein the suspension device is arranged between the frame and the axle, the frame bears the load of the vehicle, the frame is arranged on the axle, and the sensor is fixed on the frame.

Specifically, as Figure 5As shown in , the controller includes: a compression degree acquisition module 10, a distance change analysis module 20 and a vehicle load analysis module 30. Specifically, the compression degree acquisition module 10 is used to obtain the compression degree of the suspension device between the frame and the axle, the frame bears the vehicle load, and the frame is set on the axle. The distance change analysis module 20 is used to obtain the distance change information between the frame and the axle based on the compression degree, and the vehicle load analysis module 30 is used to determine the change amount of the vehicle load based on the distance change information, so as to realize the measurement of the vehicle load.
