[0032] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0033] The following describes the synchronous control method and device of the temporary support cylinder of an embodiment of the present application with reference to the accompanying drawings.

[0034] Figure 1 A schematic diagram of a synchronous control system for a temporary support cylinder provided in an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the synchronous control system of the temporary support oil cylinder includes a temporary support, a first oil cylinder and a second oil cylinder, a first solenoid valve, a second solenoid valve, and an electronic device;

[0035] Among them, a first displacement sensor and a first pressure sensor are arranged on the first oil cylinder, and a second displacement sensor and a second pressure sensor are arranged on the second oil cylinder.

[0036] The first oil cylinder and the second oil cylinder are both connected to the temporary support, and the first oil cylinder is connected to the first solenoid valve, and the second oil cylinder is connected to the second solenoid valve.

[0037] The electronic device is used to control the first solenoid valve and the second solenoid valve according to the first displacement corresponding to the piston of the first cylinder collected by the first displacement sensor, the first pressure of the first cylinder collected by the first pressure sensor, the second displacement corresponding to the piston of the second cylinder collected by the second displacement sensor, and the second pressure of the second cylinder collected by the first pressure sensor, so as to synchronize the displacement of the first cylinder and the second cylinder.

[0038] In some embodiments, the electronic device may be a controller, a host computer, etc. This disclosure does not limit this.

[0039] Figure 2 A schematic flow chart of a synchronous control method for a temporary support cylinder provided in an embodiment of the present application.

[0040] like Figure 2 As shown, the synchronous control method of the temporary support cylinder includes the following steps:

[0041] Step 201, obtaining a first pressure corresponding to a first oil cylinder of temporary support and a first displacement corresponding to a piston of the first oil cylinder, a second pressure corresponding to a second oil cylinder and a second displacement corresponding to the piston of the second oil cylinder.

[0042] The first pressure may be measured by a first pressure sensor deployed on the first oil cylinder.

[0043] The first displacement may be measured by a first displacement sensor deployed on the first oil cylinder.

[0044] The second pressure may be measured by a second pressure sensor deployed on the second oil cylinder.

[0045] The second displacement may be measured by a second displacement sensor deployed on the second oil cylinder.

[0046] Step 202, judging whether the first oil cylinder and the second oil cylinder are synchronized according to the first displacement, the first pressure, the second displacement and the second pressure.

[0047] In some embodiments, when the difference of the first displacement minus the second displacement is greater than the displacement threshold and the difference of the second pressure minus the first pressure is greater than the pressure threshold, it is determined that the first cylinder is out of sync with the second cylinder.

[0048] The displacement threshold may be preset, for example, 5 cm, 3 cm, 1 cm, etc. This disclosure does not limit this.

[0049] The pressure threshold may be determined according to the displacement threshold, that is, when the piston of the oil cylinder moves a distance corresponding to the displacement threshold, the change in pressure may be the pressure threshold.

[0050] It should be noted that the difference between the first displacement and the second displacement is greater than the displacement threshold, and the difference between the second pressure and the first pressure is greater than the pressure threshold, indicating that the displacement of the first cylinder is greater than the displacement of the second cylinder, and the pressures in the first cylinder and the second cylinder are normal, so it is determined that the first cylinder and the second cylinder are not synchronized.

[0051] In some embodiments, when the difference between the second displacement and the first displacement is greater than a displacement threshold and the difference between the first pressure and the second pressure is greater than a pressure threshold, it is determined that the first cylinder is out of sync with the second cylinder.

[0052] It should be noted that the difference between the second displacement and the first displacement is greater than the displacement threshold, and the difference between the first pressure and the second pressure is greater than the pressure threshold, indicating that the displacement of the second cylinder is greater than the displacement of the first cylinder, and the pressures in the first and second cylinders are normal, so it is determined that the first cylinder and the second cylinder are not synchronized.

[0053] In some embodiments, when the absolute value of the difference between the first displacement and the second displacement is less than or equal to the displacement threshold, and the absolute value of the difference between the first pressure and the second pressure is less than or equal to the pressure threshold, it is determined that the first cylinder is synchronized with the second cylinder.

[0054] It should be noted that the absolute value of the difference between the first displacement and the second displacement is less than or equal to the displacement threshold, and the absolute value of the difference between the first pressure and the second pressure is less than or equal to the pressure threshold, indicating that the displacement of the first cylinder is basically synchronized with the displacement of the second cylinder, and the pressures in the first cylinder and the second cylinder are normal, so it is determined that the first cylinder is synchronized with the second cylinder.

[0055] Step 203, when the first cylinder and the second cylinder are not synchronized, determine a first control parameter of a first solenoid valve corresponding to the first cylinder and a second control parameter of a second solenoid valve corresponding to the second cylinder according to the first displacement and the second displacement.

[0056] In some embodiments, when the difference between the first displacement and the second displacement is greater than the displacement threshold, the first control parameter is used to control the first solenoid valve to increase the displacement of the first cylinder at a first speed; the second control parameter is used to control the second solenoid valve to slowly increase the displacement of the first cylinder at a second speed, and the first speed is greater than the second speed, thereby controlling the displacement of the first cylinder to be synchronized with the displacement of the second cylinder.

[0057] In some embodiments, the relationship between the first speed and the second speed can be determined according to the difference between the first displacement and the second displacement. The greater the difference, the greater the difference between the first speed and the second speed.

[0058] In some embodiments, when the difference between the second displacement and the first displacement is greater than the displacement threshold, the first control parameter is used to control the first solenoid valve to increase the displacement of the first cylinder at a third speed; the second control parameter is used to control the second solenoid valve to slowly increase the displacement of the first cylinder at a fourth speed, and the third speed is less than the fourth speed, thereby controlling the displacement of the first cylinder to be synchronized with the displacement of the second cylinder.

[0059] In some embodiments, the relationship between the third speed and the fourth speed can be determined according to the difference between the first displacement and the second displacement. The greater the difference, the greater the difference between the fourth speed and the third speed.

[0060] Step 204: Control the first solenoid valve based on the first control parameter, and control the second solenoid valve based on the second control parameter.

[0061] After the first control parameter and the second control parameter are determined, the first solenoid valve and the second solenoid valve can be synchronously controlled to synchronize the first solenoid valve with the second solenoid valve.

[0062] In this embodiment, the first pressure corresponding to the first oil cylinder of the temporary support and the first displacement corresponding to the piston of the first oil cylinder, the second pressure corresponding to the second oil cylinder and the second displacement corresponding to the piston of the second oil cylinder are first obtained, and then the first oil cylinder and the second oil cylinder are judged to be synchronous according to the first displacement, the first pressure, the second displacement and the second pressure. In the case that the first oil cylinder and the second oil cylinder are not synchronous, the first control parameter of the first solenoid valve corresponding to the first oil cylinder and the second control parameter of the second solenoid valve corresponding to the second oil cylinder are determined according to the first displacement and the second displacement. Finally, the first solenoid valve is controlled based on the first control parameter, and the second solenoid valve is controlled based on the second control parameter. In this way, it is possible to determine whether the first oil cylinder and the second oil cylinder are synchronous in real time according to the first displacement and the first pressure of the first oil cylinder, the second displacement and the second pressure of the second oil cylinder, and in the case of being not synchronous, the displacements of the first oil cylinder and the second oil cylinder are adjusted respectively to ensure the displacement consistency of the first oil cylinder and the second oil cylinder, thereby improving the support stability during the excavation process.

[0063] Figure 3 The following is a flow chart of a synchronous control method of a temporary support cylinder provided in an embodiment of the present application. Figure 3 As shown, the synchronous control method of the temporary support cylinder may include the following steps:

[0064] Step 301, obtaining a first pressure corresponding to a first oil cylinder of temporary support and a first displacement corresponding to a piston of the first oil cylinder, a second pressure corresponding to a second oil cylinder and a second displacement corresponding to the piston of the second oil cylinder.

[0065] Step 302, judging whether the first oil cylinder and the second oil cylinder are synchronized according to the first displacement, the first pressure, the second displacement and the second pressure.

[0066] The specific implementation forms of step 301 and step 302 can refer to the detailed descriptions in other embodiments of the present disclosure, and will not be described in detail here.

[0067] Step 303, when the first cylinder and the second cylinder are not synchronized, determine the second displacement to be moved corresponding to the piston of the first cylinder and the third displacement to be moved corresponding to the piston of the second cylinder according to the first displacement, the second displacement, and the first displacement to be moved corresponding to the temporary support.

[0068] In some embodiments, when the first displacement is greater than the second displacement, a first difference of the first displacement minus the second displacement is determined, and then the second displacement to be moved is determined to be the first displacement to be moved, and the third displacement to be moved is the sum of the first difference and the first displacement to be moved.

[0069] In some embodiments, when the second displacement is greater than the first displacement, a second difference between the second displacement and the first displacement is determined, and then the second displacement to be moved is determined to be the sum of the second difference and the first displacement to be moved, and the third displacement to be moved is the first displacement to be moved.

[0070] Step 304: Determine a first control parameter of the first solenoid valve according to the second displacement to be moved.

[0071] Step 305: Determine a second control parameter of the second solenoid valve according to the third displacement to be moved.

[0072] In some embodiments, a mapping relationship table between the displacement to be moved and the control parameter of the solenoid valve can be determined. Then, the mapping relationship table is queried according to the second displacement to be moved to obtain the first control parameter, and the mapping relationship table is queried according to the third displacement to be moved to determine the second control parameter.

[0073] Step 306: Control the first solenoid valve based on the first control parameter, and control the second solenoid valve based on the second control parameter.

[0074] In this embodiment, when the first oil cylinder and the second oil cylinder are not synchronized, the second displacement to be moved corresponding to the piston of the first oil cylinder and the third displacement to be moved corresponding to the piston of the second oil cylinder are determined according to the first displacement, the second displacement, and the first displacement to be moved corresponding to the temporary support, the first control parameter of the first solenoid valve is determined according to the second displacement to be moved, and the second control parameter of the second solenoid valve is determined according to the third displacement to be moved, and finally the first solenoid valve is controlled based on the first control parameter, and the second solenoid valve is controlled based on the second control parameter. In this way, the first control parameter corresponding to the first solenoid valve and the second control parameter corresponding to the second solenoid valve can be accurately determined based on the first displacement and the second displacement, thereby improving the displacement control accuracy of the first oil cylinder and the second oil cylinder, and more accurately performing synchronous adjustment on the first oil cylinder and the second oil cylinder.

[0075] In some embodiments, when the absolute value of the difference between the first displacement and the second displacement is less than or equal to the displacement threshold, and the absolute value of the difference between the first pressure and the second pressure is greater than the pressure threshold, it is determined that the first cylinder and / or the second cylinder has failed. In this way, it is possible to determine whether the cylinder has failed, and in the case of a cylinder failure, the displacement of the cylinder can be controlled without further determining the control parameters of the solenoid valve, thereby improving safety.

[0076] In some embodiments, when the absolute value of the difference between the first displacement and the second displacement is greater than the displacement threshold, and the absolute value of the difference between the first pressure and the second pressure is less than or equal to the pressure threshold, it is determined that the first displacement sensor and / or the second displacement sensor is faulty. Thus, it is possible to determine whether the displacement sensor is faulty, and when the displacement sensor is faulty, the displacement of the oil cylinder can be controlled without further determining the control parameters of the solenoid valve, thereby improving safety.

[0077] The first displacement sensor is a sensor on the first oil cylinder for measuring the displacement of the piston of the first oil cylinder, and the second displacement sensor is a sensor on the second oil cylinder for measuring the displacement of the piston of the second oil cylinder.

[0078] In order to implement the above embodiment, the present application also proposes a synchronous control device for a temporary support cylinder.

[0086] When the difference between the second displacement and the first displacement is greater than the displacement threshold, and the difference between the first pressure and the second pressure is greater than the pressure threshold, it is determined that the first cylinder and the second cylinder are not synchronized; or,

[0087] When the absolute value of the difference between the first displacement and the second displacement is less than or equal to the displacement threshold, and the absolute value of the difference between the first pressure and the second pressure is less than or equal to the pressure threshold, it is determined that the first cylinder is synchronized with the second cylinder.

[0088] Further, in a possible implementation of the embodiment of the present application, the determination module 403 is used to:

[0089] Determine the second displacement to be moved corresponding to the piston of the first oil cylinder and the third displacement to be moved corresponding to the piston of the second oil cylinder according to the first displacement, the second displacement, and the first displacement to be moved corresponding to the temporary support;

[0090] Determining a first control parameter of the first solenoid valve according to the second displacement to be moved;

[0091] A second control parameter of the second solenoid valve is determined according to the third displacement to be moved.

[0092] Further, in a possible implementation of the embodiment of the present application, the determination module 403 is used to: determine a first difference value of the first displacement minus the second displacement when the first displacement is greater than the second displacement;

[0094] Further, in a possible implementation of the embodiment of the present application, the determination module 403 is used to:

[0095] If the second displacement is greater than the first displacement, determining a second difference of the second displacement minus the first displacement;

[0096] The second displacement to be moved is determined to be the sum of the second difference and the first displacement to be moved, and the third displacement to be moved is the first displacement to be moved.

[0097] Furthermore, in a possible implementation manner of the embodiment of the present application, a processing module is also included, which is used to:

[0098] When the absolute value of the difference between the first displacement and the second displacement is less than or equal to the displacement threshold, and the absolute value of the difference between the first pressure and the second pressure is greater than the pressure threshold, it is determined that the first cylinder and / or the second cylinder fails.

[0101] The first displacement sensor is a sensor on the first oil cylinder for measuring the displacement of the piston of the first oil cylinder, and the second displacement sensor is a sensor on the second oil cylinder for measuring the displacement of the piston of the second oil cylinder.

[0102] It should be noted that the aforementioned explanation of the embodiment of the synchronous control method of the temporary support cylinder is also applicable to the synchronous control device of the temporary support cylinder of this embodiment, and will not be repeated here.

[0103] In this embodiment, the first pressure corresponding to the first oil cylinder of the temporary support and the first displacement corresponding to the piston of the first oil cylinder, the second pressure corresponding to the second oil cylinder and the second displacement corresponding to the piston of the second oil cylinder are first obtained, and then the first oil cylinder and the second oil cylinder are judged to be synchronous according to the first displacement, the first pressure, the second displacement and the second pressure. In the case that the first oil cylinder and the second oil cylinder are not synchronous, the first control parameter of the first solenoid valve corresponding to the first oil cylinder and the second control parameter of the second solenoid valve corresponding to the second oil cylinder are determined according to the first displacement and the second displacement. Finally, the first solenoid valve is controlled based on the first control parameter, and the second solenoid valve is controlled based on the second control parameter. In this way, it is possible to determine whether the first oil cylinder and the second oil cylinder are synchronous in real time according to the first displacement and the first pressure of the first oil cylinder, the second displacement and the second pressure of the second oil cylinder, and in the case of being not synchronous, the displacements of the first oil cylinder and the second oil cylinder are adjusted respectively to ensure the displacement consistency of the first oil cylinder and the second oil cylinder, thereby improving the support stability during the excavation process.
