[0030] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0031] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0032] Figure 1 A schematic diagram illustrating the working principle of an embodiment of this application. For example... Figure 1 As shown, the working principle involves an electronic control unit (ECU) 101 and a pump control module 102.

[0033] ECU 101, also known as "vehicle computer" or "on-board computer," is similar to a regular computer, consisting of a microcontroller, memory, input / output interface, analog-to-digital converter, and large-scale integrated circuits for shaping and driving. The ECU is primarily used to send, receive, and process various signals from the vehicle system to control the vehicle (e.g., the vibratory roller in this embodiment) to perform various tasks.

[0034] like Figure 1 As shown, the ECU 101 provided in this embodiment includes multiple modules such as engine speed setting, switch signal, vibration speed requirement, vibration ramp, and hydraulic transmission control. The engine speed setting can be adjusted using the hand throttle, and the switch signal can be adjusted using the vibration mode switch to determine the vibration speed requirement and obtain the pump control signal (displacement & current, etc.).

[0035] The pump control module 102 is used to regulate the pump's output, i.e., the pump displacement. Based on the pump displacement and the engine speed, it further controls the speed of the vibration motor, thereby driving the steel wheel to vibrate. Figure 1 As shown, the pump control module 102 provided in this embodiment includes multiple modules such as proportional solenoid valve control and pump vibration proportional solenoid valve. Additionally, the working principle also involves a motor speed sensor, typically installed near the motor, used to detect the motor's real-time / actual speed and transmit the motor speed measurement signal to the ECU 101.

[0036] In the working process, the engine speed is adjusted by the hand throttle, and the vibratory roller vibration mode (large vibration mode or small vibration mode, different vibration modes correspond to different motor speeds) is selected by the vibration mode switch, so that the ECU 101 determines the set displacement and control current of the pump and sends it to the pump control module 102, at this time, the motor obtains a target speed. At the same time, the motor speed sensor will feed back the real-time speed of the motor to the ECU 101, and the ECU 101 will compare the difference between the real-time speed of the motor and the target speed, and correct the control signal to the pump, so as to achieve the purpose of regulating the motor speed, so that the actual speed of the motor is basically consistent with the target speed.

[0037] When the ECU 101 does not receive the feedback signal of the motor speed sensor within a specified time, it will control the motor to stop rotating, so that the vibratory roller stops working, which seriously affects the construction progress. The present application aims to solve the problem that the vibratory roller cannot work when the motor speed signal is lost, and proposes a control method, device and storage medium for the vibratory roller, which calls a new pump control signal to regulate the pump when the motor speed signal is lost, so that the motor does not stop rotating and the vibratory roller can continue to work.

[0038] The control method of the vibratory roller provided by the technical scheme of the present application will be described below in conjunction with specific embodiments.

[0039] Figure 2 The flowchart of the control method of the vibratory roller provided by the embodiment of the present application Figure 1 The vibratory roller provided by the embodiment of the present application includes a steel wheel, a control system, and a speed sensor, a vibration motor, a vibration pump and an engine connected with the control system, wherein the vibration motor is installed on the steel wheel, the vibration motor and the vibration pump are connected, and the speed sensor is used to detect the speed of the vibration motor to obtain a speed signal. As shown in Figure 2 The control method includes:

[0040] S201: When the speed signal is not detected, the control system obtains a plurality of set current values in the current vibration mode, and the set current value is set by the control system when starting.

[0041] The rotation speed signal reflects the real-time rotation speed of the vibration motor, which is obtained by the rotation speed sensor and fed back to the control system. The control system can further adjust the rotation speed of the motor according to the rotation speed signal. The vibration mode specifically refers to the vibration mode of the motor of the vibration roller, and the vibration mode can be selected when the vibration roller is started according to the construction purpose. In some embodiments, the vibration roller comprises a vibration selection switch, and the selection of the motor vibration mode can be selected by using the selection switch when starting. The control signal for controlling the rotation of the motor is different under different vibration modes, and the rotation speed of the motor is also different. For example, the vibration mode can include a large vibration mode (vibration frequency f1) and a small vibration mode (vibration frequency f2), f1 < f2.

[0042] The set current value is usually used to control the pump displacement, and is one of the control signals for controlling the rotation of the vibration motor, which is set by the control system when the vibration roller is started. In actual scenarios, the set current value may be different each time due to the differences in the working conditions of the vehicle each time the vehicle is started. These set current values can be obtained from historical set parameters or recorded by the control system each time the set current value is set.

[0043] When the control system does not detect the rotation speed signal fed back by the rotation speed sensor within a specified time, it is determined that the vibration roller is currently in a vibration mode, and a plurality of set current values in the current vibration mode are obtained from the historical control signals corresponding to the current vibration mode.

[0044] S202: Determine a target current value according to the plurality of set current values.

[0045] The set current value can be obtained from the historical set parameters in the current vibration mode or from the control system record. The target current value is a control signal for controlling the current pump displacement.

[0046] Optionally, the method of determining the target current value according to the plurality of set current values can include determining the target current value as the average of the plurality of set current values. For example, the plurality of set current values can include all set current values that can be obtained in the current vibration mode, or a specified number of set current values.

[0047] Optionally, the plurality of set current values can be a plurality of set current values closest to the current time. For example, the average of the last ten set current values is determined as the plurality of set current values, and the target current value is determined according to the last ten set current values, for example, the average of the last ten set current values is determined as the target current value. After the control system obtains the plurality of set current values, the average of the plurality of set current values is calculated to determine the target current value.

[0048] S203: Control the pump displacement of the vibration pump according to the target current value.

[0049] According to the target current value determined in S202, the vibration pump of the vibratory roller is controlled, so as to realize the control of the pump displacement.

[0050] S204: According to the pump displacement and the engine speed, the speed of the vibration motor is controlled to drive the steel wheel to vibrate.

[0051] The speed of the vibration motor is determined by the pump displacement and the engine speed, and the engine speed is usually fixed in the current vibration mode. In the embodiment, when the control system fails to detect the speed signal, the target current value is determined by S202, and the pump displacement is controlled according to the target current value, so as to control the speed of the vibration motor.

[0052] In the embodiment, when the speed signal is not detected, the control system obtains a plurality of set current values in the current vibration mode, the set current values are set by the control system when starting; the target current value is determined according to the plurality of set current values; the pump displacement of the vibration pump is controlled according to the target current value; and the speed of the vibration motor is controlled according to the pump displacement and the engine speed to drive the steel wheel to vibrate. Through the application, the vibratory roller can still continue to implement the road rolling work when the speed signal is lost, which does not affect the construction progress and improves the user experience.

[0053] Optionally, according to the pump displacement and the engine speed, the speed of the vibration motor can include: within a set time length, the speed of the vibration motor is controlled according to the pump displacement and the engine speed. The set time length can be set when the vibratory roller starts each time, for example, according to the current construction scene, or the set time length of the vibratory roller can be set at one time, for example, 5 hours or 12 hours, etc. The set time length is usually the time length sufficient for the vibratory roller to complete the set task and drive the vibratory roller to the maintenance department.

[0054] Optionally, when the set time ends, the vibration motor is controlled to stop rotating. The set time is usually the time for the vibratory roller to continue to complete the set task and drive the vibratory roller to the maintenance department for maintenance. When the set time ends, the control system controls the motor to stop rotating, so as to ensure that the vibratory roller does not work for too long in the case that the speed signal is lost.

[0055] In some embodiments, when the speed signal fails to be detected, a fault information is displayed in the display instrument of the vibratory roller, and the fault information is used to indicate that the speed signal fails to be detected. For example, the fault information can be displayed as a fault code, and the fault type corresponding to the fault code can be matched from the manual of the vibratory roller. The fault information can also be directly displayed as a fault type, which is not limited herein. In the embodiment, the fault information is used to indicate that the speed signal fails to be detected.

[0056] Optionally, the remaining machine working time can also be displayed in the display instrument, and the remaining machine working time is used to remind the user to perform the fault maintenance corresponding to the fault information within the remaining machine working time. The remaining machine working time is the remaining time of the set time, and the display of the remaining machine working time in the display instrument can remind the user of the remaining working time of the vibratory roller and take measures such as stopping work and maintenance in time.

[0057] Figure 3 The display instrument of the vibratory roller provided by the embodiment of the present application is shown in the schematic view. As shown in the figure, the display instrument includes a window for displaying fault information and a window for displaying the remaining machine working time. For example, the window for displaying fault information displays “sensor failure”, which indicates that the rotation speed signal cannot be detected; and the window for displaying the remaining machine working time displays “03:28:45”, which indicates that the remaining working time of the vibratory roller is 3 hours, 28 minutes and 45 seconds, reminding the user to maintain the vibratory roller in time within this time. Figure 3

[0058] The flowchart of the control method of the vibratory roller provided by the embodiment of the present application is shown in the schematic view. Figure 4 Figure 1 As shown in the figure, the method includes: Figure 4

[0059] When the rotation speed signal is not detected:

[0060] S411: The control system acquires a plurality of set current values closest to the current time in the current vibration mode;

[0061] S412: The target current value is determined as the average of the plurality of set current values;
