[0053] In an exemplary embodiment, a lifting system is provided, as shown in FIG1 , which is a schematic diagram of the structure of the lifting system 10, including a driving member 100, a first control component 200 and a second control component 300, wherein the driving member 100 is connected to a target device 20, and is used to perform a target operation on the target device 20; the first control component 200 is connected to the driving member 100, and is used to control the driving member 100 according to a control instruction of the second control component 300, and drive the driving member 100 to perform the target operation; the second control component 300 is used to obtain a plurality of state parameters of the target device 20; the second control component 300 is connected to the first control component 200, and is used to transmit a control instruction to the first control component 200 according to a plurality of state parameters.
[0054] The various state parameters of the target device 20 may include a load weight parameter, a displacement parameter, a temperature parameter, an angle parameter, etc. of the target device 20. The second control component 300 analyzes the various state parameters of the target device 20 obtained, generates corresponding control instructions according to the analysis results, and transmits the control instructions to the first control component 200. The first control component 200 is connected to the driving member 100, and is used to receive the control instructions of the second control component 300, and flexibly adjust the operating state of the driving member 100 according to the control instructions of the second control component 300, so as to ensure that the driving member 100 can perform targeted operations according to the target parameters of the target device 20, and the driving member 100 is used to perform corresponding target operations according to the control of the first control component 200, so as to ensure the flexibility and accuracy of the lifting system 10 in performing operations.
[0055] Optionally, the driving member 100 may be a hydraulic cylinder, a cylinder, a motor, etc. The target device 20 refers to a device that needs to be lifted, lowered, etc., and the target device 20 may be a truck, a lifting platform, a crane, etc. Performing a target operation on the target device 20 may include performing operations such as lifting, lowering, position holding, and position adjustment on the target device 20. The first control component 200 may include an adjustment component, a storage component, etc. The second control component 300 may include a detection component 304, a data acquisition component, a controller, a signal processing unit, etc. The control instructions of the second control component 300 may include a lifting instruction, a lowering instruction, a stop instruction, a speed adjustment instruction, etc.
[0056] For example, in the field of unmanned dump truck technology, taking the driving member 100 as a hydraulic cylinder and the target device 20 as a truck as an example, the driving member 100 is arranged between the truck box and the truck frame. The second control component 300 is used to obtain the load weight parameters, displacement parameters, angle parameters, etc. of the truck, and analyze these parameters to generate corresponding control instructions, and transmit the generated control instructions to the first control component 200. The first control component 200 controls the direction and magnitude of the liquid pressure according to the control instruction to drive the driving member 100 to perform operations such as lifting, lowering, and position keeping, so that the truck can complete the unloading task.
[0057] In this embodiment, the second control component 300 is used to transmit control instructions to the first control component 200 in a targeted manner according to the obtained multiple state parameters, which can ensure the accuracy of the control instructions transmitted by the second control component 300; the first control component 200 is connected to the driver 100, and is used to control the driver 100 according to the control instructions of the second control component 300, drive the driver 100 to perform the target operation, and can quickly adjust the driver 100 according to different operation requirements, so that the lifting system 10 can support target devices 20 of different types and specifications, thereby improving the applicability of the lifting system 10. At the same time, the lifting system 10 is controlled at multiple levels, and the target operation of the lifting system 10 is controlled by using multiple state parameters, which can ensure the flexibility and accuracy of the lifting system 10 in performing the target operation, thereby reducing the safety risk of the lifting system 10 performing the operation.
[0058] In an exemplary embodiment, the first control component 200 includes: an energy storage element 202 for storing power energy; a power conversion element 204 connected to the energy storage element 202 for converting power energy into driving force; and a control adjustment element 206 connected to the power conversion element 204 for controlling the direction and size of the driving force.
[0059] In the technical field of unmanned dump trucks, taking the example of a driving component 100 using a hydraulic cylinder, a target device 20 being a truck, and a power source using hydraulic oil, optionally, the energy storage component 202 may be a hydraulic oil tank, the power conversion component 204 may be a hydraulic pump, the control and adjustment component 206 may be an electronically controlled hydraulic valve group, and the hydraulic oil tank, the hydraulic pump, and the electronically controlled hydraulic valve group may be connected through a hydraulic pipeline 30 to form a hydraulic circuit. Among them, the hydraulic oil tank is used to store hydraulic oil, and the hydraulic pump is used to extract and pressurize the hydraulic oil from the hydraulic oil tank, convert it into high-pressure oil, and provide the power required to drive the hydraulic cylinder or other hydraulic components. The electronically controlled hydraulic valve group is used to control the flow direction and size of the hydraulic oil, and the hydraulic cylinder or other hydraulic components perform different target operations according to the flow direction and size of the hydraulic oil.
[0060] Exemplarily, the electronically controlled hydraulic valve group may be configured with a port, which is connected to the hydraulic cylinder by means of a hydraulic line 30. The electronically controlled hydraulic valve group may switch to multiple driving functions by controlling the flow direction and size of the hydraulic oil, such as the electronically controlled hydraulic valve group may drive the hydraulic cylinder to perform operations such as lifting, lowering, and position keeping. Under normal operation of the hydraulic cylinder, when the electronically controlled hydraulic valve group drives the hydraulic cylinder to perform a position keeping operation, the hydraulic pump extracts the hydraulic oil from the hydraulic oil tank, the electronically controlled hydraulic valve group switches to a bypass function, and then circulates back to the hydraulic oil tank through the electronically controlled hydraulic valve group; when the electronically controlled hydraulic valve group drives the hydraulic cylinder to perform a lifting operation, the hydraulic pump extracts the hydraulic oil from the hydraulic oil tank, the electronically controlled hydraulic valve group switches to a lifting function, pressurizes the hydraulic oil, and delivers the pressurized hydraulic oil to the hydraulic cylinder, so that the hydraulic cylinder is extended, so that the hydraulic cylinder performs a lifting operation; when the electronically controlled hydraulic valve group drives the hydraulic cylinder to perform a lowering operation, the hydraulic pump stops working, the electronically controlled hydraulic valve group switches to a lowering function, and the hydraulic oil is diverted from the hydraulic cylinder to the hydraulic oil tank, so that the hydraulic cylinder performs a lowering operation.
[0061] In the previous exemplary embodiment, the control adjustment member 206 is also connected to the driving member 100 to transmit driving force to the driving member 100 to drive the driving member 100 to perform a lifting operation.
[0062] The electronically controlled hydraulic valve group may be configured with a port, which is connected to the hydraulic cylinder by means of a hydraulic line 30. When the electronically controlled hydraulic valve group drives the hydraulic cylinder to perform a lifting operation, the electronically controlled hydraulic valve group switches to the lifting function, the hydraulic pump extracts hydraulic oil from the hydraulic oil tank, pressurizes the hydraulic oil, and delivers the pressurized hydraulic oil to the hydraulic cylinder to extend the hydraulic cylinder. When the hydraulic cylinder reaches the desired extension amount, the electronically controlled hydraulic valve group switches to the bypass function, that is, the electronically controlled hydraulic valve group drives the hydraulic cylinder to perform the bypass function, at which time, the hydraulic line 30 between the hydraulic pump and the hydraulic cylinder is closed, that is, after the hydraulic pump extracts hydraulic oil from the hydraulic oil tank, it circulates through the electronically controlled hydraulic valve group and then returns to the hydraulic oil tank, so that the hydraulic cylinder is maintained in a lifting state.
[0063] In this embodiment, the first control assembly 200 includes an energy storage element 202, a power conversion element 204, and a control adjustment element 206. The power conversion element 204 converts the power energy into a driving force, which can meet the needs of different loads and operating conditions, thereby enhancing the flexibility of the lifting system 10. The control adjustment element 206 is used to control the flow direction and size of the driving force, which can improve the accuracy and reliability of the driving element 100 in performing the target operation, thereby improving the safety of the lifting system 10.
[0064] In the previous exemplary embodiment, the control adjustment component 206 includes: a pressure relief valve, which is used to transfer the driving force to the energy storage component 202 when the driving force reaches the power threshold.
[0065] For example, when the hydraulic cylinder has completed its extension, the electronically controlled hydraulic valve group switches to the bypass function. If the driving force (hydraulic pressure) in the hydraulic pipeline 30 between the electronically controlled hydraulic valve group and the hydraulic cylinder reaches the power threshold, the hydraulic oil in the hydraulic pipeline 30 between the electronically controlled hydraulic valve group and the hydraulic cylinder is transferred to the hydraulic oil tank through the pressure relief valve, so that the hydraulic oil in the hydraulic pipeline 30 between the electronically controlled hydraulic valve group and the hydraulic cylinder is not pumped into the hydraulic cylinder, which can avoid lifting an overweight load, thereby reducing safety risks.
[0066] In an exemplary embodiment, the second control component 300 includes: a detection component 304, which is connected to the drive control component 302, and the detection component 304 is used to obtain multiple state parameters of the target device 20 and transmit the multiple state parameters to the drive control component 302; the drive control component 302 is connected to the control adjustment component 206, and is used to transmit control instructions to the control adjustment component 206 according to the multiple state parameters.
[0067] Exemplarily, the detection component 304 is used to obtain various state parameters of the target device 20, which may include but are not limited to parameters such as temperature, pressure, position, angle and load of the target device 20. By real-time monitoring of the various state parameters of the target device 20, the second control component 300 can capture the state of the target device 20 in a timely manner, thereby providing the necessary data basis for the subsequent control of the target device 20. The detection component 304 transmits the various state parameters of the target device 20 obtained to the drive control component 302, and the drive control component 302 analyzes the various state parameters to determine the state of the target device 20, such as the drive control component 302 can determine whether the target device 20 is in an overload state or whether the target device 20 is in a lifting completion state according to the various state parameters. After the drive control component 302 analyzes the various state parameters and determines the state of the target device 20, the drive control component 302 transmits corresponding control instructions to the control adjustment component 206 according to the state of the target device 20, and these control instructions may include changing the flow direction of the driving force to switch the working mode of the control adjustment component 206, adjusting the magnitude of the driving force, etc.
[0068] In this embodiment, the drive control component 302 analyzes multiple state parameters to determine the state of the target device 20, and transmits corresponding control instructions to the control adjustment component 206 according to the state of the target device 20, which can improve the operating efficiency and accuracy of the control adjustment component 206, thereby improving the efficiency and reliability of the drive component 100 in performing the target operation.
[0069] In an exemplary embodiment, the detection member 304 includes: a first detection member 3042, which is arranged at a target position of the target device 20, and is used to obtain a first state parameter; a second detection member 3044, which is arranged at a position close to the first detection member 3042 on the target horizontal plane, and is used to obtain a second state parameter; and a third detection member 3046, which is arranged on the driving member 100, and is used to obtain a pressure parameter of the driving member 100.
[0070] For example, the driving component 100 is a hydraulic cylinder, the target device 20 is a truck, and the power energy is hydraulic oil. At the same time, the energy storage component 202 can be a hydraulic oil tank, the power conversion component 204 is a hydraulic pump, and the control and adjustment component 206 can be an electronically controlled hydraulic valve group. The first detection component 3042 can be a first angle sensor, the second detection component 3044 can be a second angle sensor, and the third detection component 3046 can be a pressure sensor. The first angle sensor, the second angle sensor, and the pressure sensor are used to collect angle parameters, position parameters, and pressure parameters related to the target device 20, and transmit the collected angle parameters, position parameters, and pressure parameters to the driving control component 302.
[0071] Optionally, the first angle sensor is installed at the tail of the truck cargo box, and is used to detect the first state parameter, which is the angle between the truck cargo box and the horizontal ground. The second angle sensor is arranged at a position close to the first detection member 3042 on the target horizontal plane, and is used to detect the second state parameter, wherein the target horizontal plane is the plane where the truck frame is located, that is, the second angle sensor is arranged at the tail of the truck frame, and the second state parameter is the angle between the truck frame and the horizontal ground. During the lifting process of the lifting system 10, the drive control member 302 is used to determine whether there is a risk of overturning of the truck cargo box according to the first state parameter and the second state parameter obtained by the first angle sensor and the second angle sensor, so as to reduce the safety risk of the lifting system 10 performing the operation. The drive control member 302 is also used to determine whether the lifting angle of the truck cargo box meets the unloading angle requirement of the goods in the truck cargo box according to the difference data of the first state parameter and the second state parameter. During the descent process of the lifting system 10, the drive control member 302 is also used to determine whether the descent angle of the truck cargo box meets the angle requirement for stopping the descent of the truck cargo box according to the difference data of the first state parameter and the second state parameter.
[0072] The pressure sensor can be arranged on the hydraulic cylinder to monitor the hydraulic oil pressure in the hydraulic cylinder and transmit the hydraulic oil pressure data to the drive control component 302 in real time. During the lifting process of the lifting system 10, the drive control component 302 determines whether the weight of the cargo in the truck cargo box exceeds the lifting threshold of the hydraulic cylinder based on the hydraulic oil pressure data in the hydraulic cylinder transmitted by the pressure sensor, which can avoid the risk of overloading the lifting system 10, thereby improving the safety of the lifting system 10. Among them, the lifting threshold is set according to the actual situation. During the descent process of the lifting system 10, the drive control component 302 determines whether the descending weight of the truck cargo box meets the weight requirement for the truck cargo box to stop descending based on the hydraulic oil pressure data in the hydraulic cylinder transmitted by the pressure sensor and the target pressure data. Among them, the target pressure data is set according to the actual situation and can be set to 0.
[0073] In this embodiment, the first detection component 3042, the second detection component 3044 and the third detection component 3046 are used to respectively obtain various state parameters of the target device 20. The drive control component 302 determines the lifting and lowering state conditions according to these parameters, which enables the drive control component 302 to output more accurate control instructions, thereby improving the accuracy of the lifting system 10 in performing operations.
[0074] In an exemplary embodiment, the lifting system 10 further includes a master control component and a scheduling component. The master control component is used to send master control instructions to the drive control component; the scheduling component is used to send scheduling instructions to the master control component.
[0075] Exemplarily, when the scheduling component sends a first scheduling instruction to the general control component, the general control component sends a lifting general control instruction to the driving control component 302 of the second control component 300 according to the first scheduling instruction. Further, the driving control component 302 sends a first control instruction to the control adjustment component 206 of the first control component 200 according to the lifting general control instruction, wherein the first control instruction is a lifting instruction. Taking the driving component 100 as a hydraulic cylinder, the target device 20 as a truck, and the power energy as hydraulic oil as an example, optionally, the energy storage component 202 can be a hydraulic oil tank, the power conversion component 204 is a hydraulic pump, and the control adjustment component 206 can be an electronically controlled hydraulic valve group. After the electronically controlled hydraulic valve group receives the lifting instruction sent by the driving control component 302, the electronically controlled hydraulic valve group switches to the lifting function, the hydraulic pump draws hydraulic oil from the hydraulic oil tank, pressurizes the hydraulic oil, and delivers the pressurized hydraulic oil to the hydraulic cylinder, so that the hydraulic cylinder is extended to drive the hydraulic cylinder to perform the lifting operation. The drive control component 302 receives the pressure parameter transmitted by the third detection component 3046 (pressure sensor), wherein the pressure parameter is the hydraulic oil pressure data in the hydraulic cylinder transmitted by the pressure sensor. The drive control component 302 determines whether the weight of the goods in the truck cargo box exceeds the lifting threshold of the hydraulic cylinder based on the pressure parameter. When the weight of the goods in the truck cargo box does not exceed the lifting threshold of the hydraulic cylinder, the electronically controlled hydraulic valve group continues to be in the lifting function state according to the lifting instruction of the drive control component 302, that is, the electronically controlled hydraulic valve group drives the hydraulic cylinder to continue to perform the lifting operation. If the weight of the goods in the truck cargo box exceeds the lifting threshold of the hydraulic cylinder, the lifting system 10 is at risk of overloading and lifting. The drive control component 302 feeds back the information of the overloading and lifting risk to the master control component, and the master control component feeds back the information to the scheduling component.
[0076] At the same time, after the electronically controlled hydraulic valve group switches to the lifting function, the driving control component 302 is also used to judge whether there is a risk of the truck box turning over backwards according to the first state parameter and the second state parameter transmitted by the first detection component 3042 (first angle sensor) and the second detection component 3044 (second angle sensor). If there is no risk of turning over backwards, the electronically controlled hydraulic valve group continues to be in the lifting function state according to the lifting instruction of the driving control component 302, that is, the electronically controlled hydraulic valve group drives the hydraulic cylinder to continue to perform the lifting operation. And the driving control component 302 can also judge whether the lifting angle of the truck box meets the unloading angle requirement of the goods in the truck box according to the difference data of the first state parameter and the second state parameter. When the lifting angle of the truck box meets the unloading angle requirement, the driving control component 302 transmits the lifting holding instruction to the electronically controlled hydraulic valve group, and the electronically controlled hydraulic valve group switches to the bypass function, and the electronically controlled hydraulic valve group drives the hydraulic cylinder to perform the position holding operation, and this lifting operation is completed.
[0077] The driving control component 302 feeds back the information of the completion of the lifting operation to the general control component, and the general control component feeds back the information to the scheduling component. In the above, if the driving control component 302 judges that the lifting angle of the truck cargo box does not meet the unloading angle requirement of the goods in the truck cargo box according to the difference data of the first state parameter and the second state parameter, the electronically controlled hydraulic valve group drives the hydraulic cylinder to continue to perform the lifting operation until the lifting angle of the truck cargo box meets the unloading angle requirement of the goods in the truck cargo box. During the process of the electronically controlled hydraulic valve group driving the hydraulic cylinder to continue to perform the lifting operation, if the driving control component 302 judges that there is a risk of the truck cargo box flipping back according to the first state parameter and the second state parameter, the electronically controlled hydraulic valve group drives the hydraulic cylinder to perform the position holding operation. At this time, if the lifting angle of the truck cargo box still does not meet the unloading angle requirement of the goods in the truck cargo box, it means that the lifting operation fails, and the driving control component 302 transmits the corresponding first state parameter and the second state parameter to the general control component, and the general control component transmits the first state parameter and the second state parameter to the scheduling component, and the scheduling component re-plans the lifting operation of the lifting system 10.
[0078] When the dispatching component sends a second dispatching instruction to the master control component, the master control component sends a descending master control instruction to the drive control component 302 according to the second dispatching instruction. Further, the drive control component 302 sends a second control instruction to the control adjustment component 206 of the first control component 200 according to the descending master control instruction, wherein the second control instruction is a descending instruction. After the electronically controlled hydraulic valve group receives the descending instruction sent by the drive control component 302, the electronically controlled hydraulic valve group switches to the descending function, the hydraulic pump stops working, and the hydraulic pipeline 3030 between the hydraulic cylinder and the hydraulic oil tank is opened. At this time, the hydraulic cylinder automatically retracts under the weight of the truck cargo box, and the hydraulic oil returns from the hydraulic cylinder to the hydraulic oil tank. The drive control component 302 determines whether the difference data between the first state parameter and the second state parameter is 0. When the difference data between the first state parameter and the second state parameter is not 0, the electronically controlled hydraulic valve group continues to be in the descending function state according to the descending instruction of the drive control component 302, that is, the electronically controlled hydraulic valve group drives the hydraulic cylinder to continue to perform the descending operation. When the difference data between the first state parameter and the second state parameter is 0, the drive control component 302 determines whether the pressure parameter transmitted by the third detection component 3046 (pressure sensor) is the target pressure data, wherein the pressure parameter is the hydraulic oil pressure data in the hydraulic cylinder, and the target pressure data can be set to 0. When the hydraulic oil pressure data in the hydraulic cylinder is 0, the electronically controlled hydraulic valve group drives the hydraulic cylinder to perform the position holding operation, and the current descending operation is completed. In the above, if the hydraulic oil pressure data in the hydraulic cylinder is not 0, the electronically controlled hydraulic valve group continues to be in the descending function state according to the descending instruction of the drive control component 302, that is, the electronically controlled hydraulic valve group drives the hydraulic cylinder to continue to perform the descending operation until the hydraulic oil pressure data in the hydraulic cylinder is 0, and the drive control component 302 feeds back the information of the completion of the descending operation to the general control component, and the general control component feeds back the information to the scheduling component.
[0079] In this embodiment, the lifting system 10 also includes a master control component and a scheduling component. The master control component and the scheduling component control the second control component 300 and the first control component 200, and can make real-time dynamic adjustments to the lifting system 10 to improve the flexibility of the lifting system 10. The first control component 200 includes an energy storage component 202, a power conversion component 204, and a control adjustment component 206. The power conversion component 204 converts the power energy into a driving force, which can meet the needs of different loads and operating conditions, thereby enhancing the flexibility of the lifting system 10. The control adjustment component 206 is used to control the flow direction and size of the driving force, which can improve the accuracy and reliability of the driver 100 in performing the target operation, thereby improving the safety of the lifting system 10. The first detection member 3042, the second detection member 3044 and the third detection member 3046 are used to respectively obtain various state parameters of the target device 20, and the driving control member 302 analyzes the various state parameters to determine the state of the target device 20, and transmits corresponding control instructions to the control adjustment member 206 according to the state of the target device 20, which can improve the operating efficiency and operating accuracy of the control adjustment member 206, thereby improving the efficiency and reliability of the drive member 100 in performing the target operation. The present application performs multi-layer control on the lifting system 10, and uses various state parameters to control the target operation of the lifting system 10, which can ensure the flexibility and accuracy of the lifting system 10 in performing the target operation, thereby reducing the safety risk of the lifting system 10 in performing the operation.
[0080] The present application also provides a lifting system control method, which is applied to the above-mentioned lifting system, and the lifting system control method can be applied to the application environment shown in Figure 2. The terminal 102 communicates with the server 104 through the network. The terminal 102 sends a lifting system control request to the server 104, and the server 104 receives the lifting system control request, obtains multiple state parameters of the target device, and controls the second control component to transmit a control instruction to the first control component according to the multiple state parameters; according to the control instruction, the first control component is controlled to transmit a corresponding drive instruction to the drive component; according to the drive instruction, the drive component is controlled to perform a target operation on the target device, wherein the terminal 102 can be but is not limited to various transportation vehicles such as trucks, cranes, and cranes. The server 104 can be implemented as an independent server or a server cluster consisting of multiple servers.
[0081] In an exemplary embodiment, as shown in FIG3 , a lifting system control method is provided, which is described by taking the method applied to the server in FIG2 as an example, and includes the following steps 302 to 306. Among them:
[0082] Step 302: Acquire multiple state parameters of the target device, and control the second control component to transmit a control instruction to the first control component according to the multiple state parameters.
[0083] Step 304: According to the control instruction, control the first control component to transmit the corresponding driving instruction to the driving member.
[0084] Step 306: Control the driver to perform the target operation on the target device according to the drive instruction.
[0085] Exemplarily, the server obtains various state parameters of the target device according to the detection component pre-set on the target device, controls the second control component to determine the corresponding control instructions according to these state parameters, and sends the determined control instructions to the first control component. The server controls the first control component to determine the corresponding drive instruction according to the control instruction, and controls the drive component to perform the corresponding target operation on the target device according to the drive instruction. Among them, the target device can be but is not limited to various transportation tools such as trucks, cranes, and cranes. The various state parameters of the target device may include information such as the position, load weight, pressure data, and angle parameters of the target device. The control instructions of the second control component may include lifting instructions, lowering instructions, stop instructions, speed adjustment instructions, etc.
[0086] In this embodiment, the server obtains various state parameters of the target device based on the detection parts pre-set on the target device, and controls the second control component to determine the corresponding control instructions based on these state parameters, which can ensure the accuracy of the control instructions determined by the second control component; controls the first control component to determine the corresponding drive instructions based on the control instructions, and controls the drive component to perform the corresponding target operation on the target device, which can determine different operation requirements according to the various state parameters of the target device, and then quickly adjust the drive component, so that the lifting system can support target devices of different types and specifications, improve the flexibility and accuracy of the lifting system, and reduce the safety risks of the lifting system performing operations.
[0087] In an exemplary embodiment, the control instruction includes a first control instruction, and the method also includes: obtaining a first state parameter, a second state parameter and a pressure parameter of the target device according to the first detection member, the second detection member and the third detection member respectively; when the pressure parameter is less than a preset pressure threshold, determining whether the first state parameter is less than a preset first state threshold; when the first state parameter is less than the preset first state threshold, determining difference data according to the first state parameter and the second state parameter; when the difference data is within a preset difference range, the second control component transmits the first control instruction to the first control component.
[0088] The first control instruction refers to a lifting instruction. The detection components pre-set on the target device include a first detection component, a second detection component and a third detection component. The first state parameter, the second state parameter and the pressure parameter respectively obtained by the first detection component, the second detection component and the third detection component can monitor the working state of the target device in real time, and ensure the accuracy of the control instruction determined by the second control component.
[0089] Optionally, the server controls the second control component to perform data analysis on the first state parameter, the second state parameter and the pressure parameter. When the pressure parameter is less than a preset pressure threshold, it further determines whether the first state parameter is less than a preset first state threshold, which can ensure that the target device operates within a safe range. If the first state parameter is indeed less than the preset first state threshold, the server controls the second control component to calculate the difference data based on the first state parameter and the second state parameter. When the difference data is within the preset difference range, the server controls the second control component to transmit the first control instruction to the first control component, that is, the server controls the second control component to transmit the lifting instruction to the first control component.
[0090] In the previous exemplary embodiment, the control instruction includes a second control instruction, and the method also includes: when the second control component transmits the second control instruction to the first control component, according to the control instruction, controlling the first control component to transmit the corresponding drive instruction to the drive component; according to the drive instruction, controlling the drive component to perform the target operation; when the difference data is equal to the preset target difference, judging whether the pressure parameter is equal to the target pressure value; when the pressure parameter is equal to the target pressure value, controlling the drive component to complete the target operation.
[0091] Wherein, the second control instruction refers to a descending instruction. After the server controls the second control component to transmit the descending instruction to the first control component, it controls the first control component to transmit the corresponding driving instruction to the driver, so that the first control component drives the driver to perform a descending operation on the target device. When the server controls the first control component to transmit the corresponding driving instruction to the driver, so that the first control component drives the driver to perform a descending operation on the target device, it determines whether the difference data between the first state parameter and the second state parameter is equal to the target difference. If the difference data is equal to the target difference, it continues to determine whether the pressure parameter is equal to the target pressure value. When the pressure parameter is equal to the target pressure value, the server controls the first control component to transmit the corresponding driving instruction to the driver, so that the first control component drives the driver to complete the target operation. Wherein, the target difference and the target pressure values are set according to the actual situation, and both can be set to 0.
[0092] In this embodiment, the first detection component, the second detection component and the third detection component are used to respectively obtain various state parameters of the target device, and the drive control component is controlled to judge the lifting and lowering state conditions according to these parameters, so that the drive control component can output more accurate control instructions, thereby improving the accuracy of the lifting system's execution of operations.
[0093] In an exemplary embodiment, the method further includes: when the driving force reaches a power threshold, the first control component transmits a driving pressure relief instruction to the driving member; and transfers the driving force to the energy storage member according to the driving pressure relief instruction.
[0094] Exemplarily, the driving force in the driving member is monitored in real time. When the driving force reaches a preset power threshold, the server controls the first control component to immediately transmit a driving pressure relief instruction to the driving member, that is, the first control component drives the driving member to perform a pressure relief operation, and controls the first control component to transfer excess driving force to the energy storage member according to the driving pressure relief instruction.
[0095] In this embodiment, through effective pressure relief management, it is possible to avoid lifting excessive loads and avoid failures caused by overload, thereby reducing safety risks. At the same time, the excess driving force is transferred to the energy storage component, which can effectively store power energy and improve the energy efficiency of the lifting system.
