The SPAR-type floating wind turbine (SPAR) has become an important supporting structure for deep sea wind power due to its low center of gravity and good self-stability. However, the SPAR-type floating wind turbine is easily affected by the combined action of wind, wave, and current during operation, resulting in large motion response and affecting the stability of operation.

DETAILED DESCRIPTION

[0034] In order for those skilled in the art to better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be clearly and completely described below in conjunction with the drawings in the embodiments of the present specification. Obviously, the described embodiments are only part of the embodiments of the present specification, not all. Based on the embodiments in the present specification, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present specification.

[0035] At present, the wind power industry is developing from land to sea, from near sea to deep sea. The flow speed of sea wind is often faster and the wind speed is more stable because it is not blocked by complex terrain and dense vegetation on land, which makes the power of offshore wind turbine generally higher than that on land. The SPAR type fan platform has the characteristics of self-stability because the gravity center is far below the floating center, is suitable for a wide sea area, and can maintain good stability in deep sea environment. However, it is greatly affected by wind, wave and current and other environmental factors during work, and has a large motion response. The wave energy device currently has problems such as high power generation cost, low energy conversion efficiency and difficult maintenance.

[0036] In view of the root causes of the above problems, the present specification realizes the cooperative power generation of wave energy and wind energy in the fan integrated power generation system, and on the other hand, the controller forms a target torque under the action of wave, and the target torque is fed back to the wave wing module and column structure through the main shaft, effectively inhibiting the up and down floating and structural sway of the platform under the action of strong wave, improving the adaptability of the fan integrated power generation system to complex sea conditions, and enhancing the stability of platform operation and the reliability of power generation system.

[0037] Reference Figure 1As shown, the embodiment of the present application also provides a control method of a fan integrated power generation system, which is applied to a fan integrated power generation system, and the fan integrated power generation system at least comprises a fan, a wave wing module and a power generation module; the bottom of the fan is provided with a column; the wave wing module is arranged around the outside of the column; the power generation module is arranged inside the column; the wave wing module at least comprises a wave wing and a power generation ring; the wave wing is fixed to the annular outer surface of the power generation ring; the power generation ring is arranged around the outside of the column; the power generation module at least comprises a main shaft, a controller, a driven shaft and a generator; wherein one end of the main shaft is connected with the power generation ring, and the other end is connected with the controller; the controller is connected with the generator through the driven shaft; and the method comprises:

[0038] S101: when there is wave on the sea, the wave wing in the wave wing module is driven to rotate the power generation ring around the column by the wave, and the main shaft in the power generation module is used to drive the gear box to rotate to generate the first type of power;

[0039] S102: in the process of power generation, the controller is used to form a target torque opposite to the rotation direction of the driven shaft; wherein the target torque is used to act on the wave wing module through the main shaft, so that the wave wing module generates an acting force opposite to the direction of the wave to weaken the swing of the column.

[0040] In some embodiments, specific implementation can include:

[0041] In the fan integrated power generation system, the platform structure is arranged in the sea area, when there is wave, the wave will cause periodic up and down floating or pitching disturbance to the whole platform. At this time, the wave wing module arranged outside the column will cross the water body with the floating of the column, forming relative flow between the water body. The wave wing will generate tangential thrust due to the bias installation angle, and then drive the power generation ring around the column to rotate along the column axis.

[0042] The rotation of the power generation ring is transmitted to the power generation module arranged inside the column through the main shaft, drives the gear box and the driven shaft to rotate, and finally drives the generator to generate the first type of wave energy. At the same time, the fan arranged at the upper part drives the wind wheel to rotate by the wind force, realizes the second type of wind energy, and realizes the dual-energy complementary power generation mechanism.

[0043] In this process, to suppress the excessive platform response caused by waves, the controller analyzes the rotation state of the driven shaft in real time. When the driven shaft speed exceeds the set threshold, the controller forms a target torque opposite to the rotation direction of the driven shaft by adjusting the electromagnetic load or applying mechanical braking. The target torque is transmitted back to the power generation ring along the original transmission path through the gearbox and main shaft, and finally acts on the wave wing module.

[0044] In this way, through the structural path reaction, the wave wing module will receive an opposite structural reaction force when it is pushed by the next period of waves, slowing down its rotation trend and reducing the vertical floating or pitching amplitude of the entire platform. This process forms an adaptive and adjustable dynamic damping mechanism, effectively improving the stability of the system in wave conditions.

[0045] In some embodiments, the wave wing modules are arranged as multiple independent structures along the height direction of the column, i.e., each layer is a wave wing module, and multiple modules are arranged in layers outside the column. Each wave wing module includes a number of wave wings, which are installed in a ring or segmented symmetrically outside the corresponding power generation ring. The wave wing modules at different levels can be designed differently in terms of structural density, wing shape, angle offset, etc., according to the water depth, hydrodynamic environment, and structural stress characteristics.

[0046] For example, the upper wave wing module arranged near the sea surface can adopt a dense arrangement of wave wings, a small angle of attack, and a thin wing structure design to enhance the rapid response capability and high-frequency driving performance, as it directly contacts the shallow waves with high frequency and strong disturbance. The lower wave wing module arranged at a deeper position mainly acts on the relatively stable but high-energy waves in deep water, and is suitable for a relatively sparse arrangement of wave wings, a large angle of attack, and a thick wing structure to achieve stronger torque output and buffer response, thereby improving the adaptability and energy conversion efficiency of the system under different depth wave actions.

[0047] In addition, each layer of wave wing module can also be provided with a controllable locking mechanism for determining whether to enable or disable the corresponding level of wave wing module to participate in work according to real-time sea conditions. For example, in rough sea conditions, to prevent excessive torque transmission or avoid equipment fatigue, the middle or lower wave wing module can be temporarily closed by controlling the locking mechanism, leaving only the upper module to participate in power generation, thereby reducing system load and improving structural safety. Under medium and low intensity wave conditions, all wave wing modules can be unlocked for cooperative operation to enhance the rotation response capability and improve the overall power generation efficiency.

[0048] Meanwhile, the wave wing airfoil shape in each wave wing module can be designed differently according to fluid dynamic requirements, for example, optimized as a gradually curved airfoil with varying curvature, or provided with a fold angle structure at the trailing edge of the wing, to adapt to the hydrodynamic characteristics in different water depths, wave heights and flow rates, improve the energy capture efficiency and torque output performance of each module in its action layer, and realize the collaborative compensation and energy grading conversion among the multi-layer wave wing modules.

[0049] By designing the wave wing system as a multi-layer wave wing module structure along the height direction of the column, and combining the differentiated configuration of each module in terms of distribution density, airfoil parameters and adjustable locking control strategy, the self-adaptive response capability to wave characteristics at different water depths is realized. This structure not only effectively improves the overall wave energy capture efficiency, but also enhances the safety redundancy and hierarchical response control capability of the system in strong wave conditions. Each wave wing module can be started and stopped independently according to the sea conditions, realizing modular management and dynamic load distribution, and thus building a multi-level, configurable wave energy acquisition and regulation mechanism. This design gives the system higher flexibility and environmental adaptability, significantly improving the operation stability of the platform and the continuous reliability of the power generation system.

[0050] In some embodiments, the wave wing module is also provided with a stowable mechanism for stowing the wave wing module as a whole in a non-working state or in severe sea conditions, to reduce the exposed area of the structure, reduce the force impact and improve the durability of the system. Specifically, the wave wing and the power generation ring can be relatively moved through a hinged connection or a slide rail guide structure. When a shutdown instruction is received or the system detects an extreme condition, a driving mechanism controls the wave wing to fold inward radially or slide into the inner cavity of the module body, so that it is in contact with the power generation ring structure and is in a stowed state, avoiding continuous external impact. At the same time, the stowable structure can cooperate with a locking device to realize reliable positioning in the stowed or deployed state, ensuring the mechanical safety and response flexibility of the system during start-up and shutdown. This stowable design further enhances the environmental adaptability and system survivability of the wave wing module, and is suitable for deep sea application scenarios where extreme weather occurs frequently.

[0051] Based on the above embodiments, on the one hand, the wave energy and wind energy are cooperatively generated in the wind turbine integrated power generation system, and on the other hand, the controller forms a target torque under the action of the wave, and the target torque is fed back to the wave wing module and the column structure through the main shaft, effectively suppressing the up-and-down floating and structural sway of the platform under the action of strong waves, improving the adaptability of the wind turbine integrated power generation system to complex sea conditions, and enhancing the stability of the platform operation and the reliability of the power generation system.

[0052] In some embodiments, a wind monitoring module is arranged on the wind turbine, and when waves exist on the sea, the wave wings in the wave wing module are driven by the waves to drive the power generation ring to rotate around the column, and the main shaft in the power generation module drives the gear box to rotate to generate the first type of power. When the wind turbine integrated power generation system is implemented, the following contents can also be included:

[0053] S1: When waves exist on the sea, the wind speed of the sea area where the wind turbine integrated power generation system is located is obtained by the wind monitoring module, and whether the collected wind speed exceeds the preset wind speed threshold is judged;

[0054] S2: When the collected wind speed is greater than the preset wind speed threshold, the wave wings in the wave wing module are driven by the waves to drive the power generation ring to rotate around the column, and the main shaft in the power generation module drives the gear box to rotate to generate the first type of power.

[0055] Specifically, in the operation process of the wind turbine integrated power generation system, the system first starts the wind monitoring module to monitor the wind speed of the current sea area in real time. The wind monitoring module can use an anemometer or a sensing component installed on the top of the wind turbine to continuously collect environmental wind speed data. The control logic compares the real-time collected wind speed value with the wind speed threshold set in the system to determine whether the current wind condition is suitable for starting the wave energy power generation process.

[0056] When the monitored wind speed exceeds the preset threshold, the system determines that the current sea condition has reached the effective power generation condition of the combined action of waves and wind, and at this time the wave wing module is enabled to enter the working state. With the platform floating up and down under the action of waves, the wave wing module fixed to the outside of the column passes through the water body, and because of the offset angle of its structure, it generates tangential water power in the water body, so that the wave wing drives the power generation ring to rotate around the column. The rotating power generation ring drives the main shaft to rotate, and then drives the gear box to speed up the transmission, and finally drives the generator through the driven shaft to generate the first type of wave energy power generation.

[0057] Based on the above embodiment, by introducing the wind speed monitoring and threshold judgment mechanism, the sea condition can be dynamically evaluated before the wave energy power generation is started, so that the wave wing module is only enabled under stable wind conditions, and invalid starting under weak wind and weak wave conditions is avoided, thereby improving the energy utilization efficiency and intelligent response ability of the system.

[0058] In some embodiments, the controller forms a target torque opposite to the rotation direction of the driven shaft, and when the wind turbine integrated power generation system is implemented, the following contents can also be included:

[0059] S1: In the power generation process, the rotation speed of the driven shaft is obtained by the controller, and the rotation speed is compared with the preset rotation speed threshold;

[0060] S2: When the rotational speed of the driven shaft is detected to be greater than the preset rotational speed threshold, a target torque opposite to the rotation direction of the driven shaft is formed by the controller.

[0061] Specifically, during power generation, the controller continuously monitors the operating state of the driven shaft, including key parameters such as rotational speed, rotation direction, torque, etc. Among them, the rotational speed is an important indicator reflecting the intensity of wave excitation and power generation. The controller collects rotational speed data in real time through a rotation sensor connected to the driven shaft, and compares it with the system preset rotational speed threshold for judgment. This threshold can be preset according to factors such as wave conditions, motor load characteristics, and platform structure parameters, to identify the degree of system dynamic response under high wave excitation conditions.

[0062] When the controller detects that the rotational speed of the driven shaft exceeds the preset threshold, the system determines that the wave excitation intensity under the current sea conditions is high, and there is a risk of excessive platform response. At this time, the controller triggers the internal execution module to adjust the electromagnetic load on the generator side, or controls the brake assembly to apply additional braking resistance, thereby forming a target torque inside the system that is opposite to the current rotation direction of the driven shaft. The target torque acts on the wave wing module along the transmission chain path (driven shaft → gear box → main shaft → power generation ring), restricting its rotational movement, thereby indirectly suppressing the up-and-down floating and excessive response of the platform.

[0063] This process can dynamically adjust the size of the reverse torque in real time as the wave excitation intensity changes, forming a flexible and controllable dynamic damping mechanism.

[0064] Based on the above embodiment, the wave excitation state of the system can be judged based on the real-time rotational speed of the driven shaft, and a target torque opposite to the rotation direction can be intelligently generated under high excitation conditions, thereby effectively suppressing the violent floating reaction of the platform caused by the excessive rotation speed of the wave wing. This control strategy not only improves the stability and response safety of the power generation system, but also enhances the adaptability of the platform structure to complex sea conditions, with significant anti-disturbance and practical engineering value.

[0065] In some embodiments, referring to Figure 2 The controller includes a gear box, a brake disc, and a clutch; the power generation module further includes a main bearing; wherein the gear box is located on the driven shaft near the main shaft, the brake disc and the clutch are located on the driven shaft, and the main bearing is fixed to the main shaft near the power generation ring. The method can further include the following content when implemented:

[0066] When the rotational speed of the driven shaft is detected to exceed the preset rotational speed threshold, mechanical braking is applied through the brake disc to increase the target torque.

[0067] Specifically, the gear box is located on the driven shaft, close to one side of the main shaft, for realizing speed increase and adjustment of rotation transmission; the brake disc and the clutch are arranged on the driven shaft, respectively for starting and stopping control of the power generation path and dynamic adjustment of the rotation resistance; the main bearing is arranged on one side of the main shaft close to the power generation ring, for supporting stable operation of the main shaft and reducing rotation wobble.

[0068] In the specific implementation process, when the controller monitors that the rotation speed of the driven shaft exceeds the preset threshold value, indicating that the current wave excitation intensity is large and the platform response speed is fast, at this time, the control logic can trigger the brake disc to work to apply mechanical braking to the driven shaft. The brake braking not only provides additional rotation resistance, but also can jointly act with the electromagnetic load on the generator side to further enhance the target torque formed. The target torque acts on the power generation ring and the wave wing module through the main shaft path, effectively inhibiting the rotation trend, so as to achieve the purpose of limiting the wave excitation response and protecting the safety of the platform structure.

[0069] In some embodiments, referring to Figure 2 As shown in the figure, the power generation module further includes a main bearing; wherein the gear box is located on the driven shaft, close to one side of the main shaft.

[0070] In some embodiments, referring to Figure 3 As shown in the figure, the fan at least includes: a hub, a plurality of blades, a tower; wherein,

[0071] One end of the tower is fixed on the side of the stand away from the power generation module, and the other end is fixedly installed with the hub; the hub is fixedly installed with the plurality of blades.

[0072] In some embodiments, referring to Figure 4 As shown in the figure, the wave wing module further includes: a wave wing hub and a plurality of balls; wherein the wave wing hub is installed on the annular surface of the power generation ring and fixedly connected with one side of the wave wing; the plurality of balls are located on both sides of the power generation ring.

[0073] In some embodiments, referring to Figure 4 As shown in the figure, the wave wing hub of the wave wing module is provided with a spring module for providing elastic recovery capability when the wave wing is impacted by waves. The spring module is installed at the connecting part between the wave wing and the hub, and the angle of the wave wing is adaptively adjusted through the elastic structure. When the wave impact intensity is large, the wave wing is deflected under the action of water power, and the spring assembly is compressed to store energy; when the water flow impact is weakened or the direction is changed, the spring releases the elastic energy, so that the wave wing quickly recovers to the preset angle, or deflects in the opposite direction, thereby forming a counter thrust opposite to the current water flow direction, further generating an additional target torque in the rotation process of the power generation ring.

[0074] Further, the spring module further comprises an adjustable locking structure for dynamically adjusting the effective working length of the spring according to the sea conditions. When the wave intensity is large, the locking structure controls the spring to extend to a longer state, providing a larger buffer stroke and a more flexible angle adjustment capability to adapt to high-amplitude wave impact; when the wave intensity is small, the locking structure limits the spring to a shorter stroke, improving the response stiffness and adjustment speed to ensure that strong posture stability and rotational response sensitivity can be maintained under weak waves.

[0075] This structure not only improves the adaptability of the wave wing to different wave intensities, but also further optimizes the generation path of the reverse torque through the variable spring stroke adjustment mechanism, so that the power generation ring has good damping response and energy capture performance in variable sea conditions, thereby improving the stability, power generation efficiency and structural control effect of the system.

[0076] In specific implementation, a preset wave intensity detection module is used to detect the wave intensity value in real time. When it is detected that the wave intensity value is less than a preset threshold, the locking structure is locked at the lower end position of the spring, so that the working length of the spring is less than a first preset length; when it is detected that the wave intensity value is greater than the preset threshold, the locking structure is unlocked or moved upward to a set position, so that the working length of the spring is greater than a second preset length; wherein the preset wave intensity detection module can include any one or a combination of an accelerometer, a pressure sensor or a radar range finder, for obtaining response data of the platform in the wave environment and evaluating the wave intensity accordingly; the first preset length is the minimum effective deformation range of the spring in the non-working state, for limiting the spring response under low wave intensity; the second preset length is the minimum critical length of the spring with normal elastic deformation capability, for releasing the energy storage and recovery capability of the spring under high wave intensity, thereby realizing the synergistic effect of wave wing angle adjustment and reverse torque auxiliary regulation.

[0077] In the above manner, when the wave intensity is small, the spring basically does not participate in the stress response process of the wave wing, which can avoid unnecessary elastic interference or trigger an incorrect compensation mechanism under weak waves, ensuring the stability and accuracy of the system response; when the wave intensity increases, the spring has sufficient deformation, which can store and release elastic energy during the deflection of the wave wing, forming a restoring force opposite to the deflection direction, effectively assisting the posture adjustment of the wave wing, and enhancing the reverse torque adjustment capability of the power generation ring, thereby improving the wave resistance and vibration suppression performance of the platform.

[0078] In some embodiments, the angle between the wave wing and the radial direction of the power generation ring is a preset bias angle; the stand column is a variable diameter structure, and a gravity center adjustment module is arranged inside the stand column.

[0079] In some embodiments, in order to improve the wave energy capture efficiency and the platform stability, the wave wing is arranged at a preset offset angle relative to the radial direction of the power generation ring. The offset angle enables the wave wing to generate more significant tangential water power when encountering water flow in the up-down direction, thereby enhancing the rotational driving force of the power generation ring during the vertical movement of the floating platform, and realizing more efficient wave energy conversion.

[0080] In some embodiments, as shown in Figure 3 The wind turbine integrated power generation system further comprises a mooring module located at the bottom of the column, wherein the mooring module at least comprises an anchor chain, one end of the anchor chain is connected to the column, and the other end is fixed in a target sea area.

[0081] As can be seen from the above, the control method of the wind turbine integrated power generation system provided by the embodiments of the present application is applied to a wind turbine integrated power generation system, which at least comprises a wind turbine, a wave wing module and a power generation module. The bottom of the wind turbine is provided with a column. The wave wing module is arranged around the outside of the column. The power generation module is arranged inside the column. The wave wing module at least comprises a wave wing and a power generation ring. The wave wing is fixed to the annular outer surface of the power generation ring. The power generation ring is arranged around the outside of the column. The power generation module at least comprises a main shaft, a controller, a driven shaft and a generator. One end of the main shaft is connected to the power generation ring, and the other end is connected to the controller. The controller is connected to the generator through the driven shaft. The method comprises: when there is wave on the sea, the wave wing in the wave wing module is driven by the wave to drive the power generation ring to rotate around the column, and the main shaft in the power generation module is used to drive the gear box to rotate to generate the first type of power. At the same time, the wind turbine is driven by the wind to generate the second type of power. During power generation, the controller forms a target torque opposite to the rotation direction of the driven shaft.

[0098] It can be seen from the above that the control device of the fan integrated power generation system provided by the embodiment of the present specification is applied to the fan integrated power generation system, and the fan integrated power generation system at least includes a fan, a wave wing module, and a power generation module; the bottom of the fan is provided with a column; the wave wing module is arranged around the outside of the column; the power generation module is arranged inside the column; the wave wing module at least includes a wave wing and a power generation ring; the wave wing is fixed to the annular outer surface of the power generation ring; the power generation ring is arranged around the outside of the column; the power generation module at least includes a main shaft, a controller, a driven shaft, and a generator; wherein one end of the main shaft is connected with the power generation ring, and the other end is connected with the controller; the controller is connected with the generator through the driven shaft; the method includes: when there is a wave on the sea, the wave wing in the wave wing module is driven by the wave to drive the power generation ring to rotate around the column, and the main shaft in the power generation module is used to drive the gear box to rotate to generate the first type of power; at the same time, the fan is driven by the wind to generate the second type of power; in the process of power generation, the controller is used to form a target torque opposite to the rotation direction of the driven shaft; wherein the target torque is used to act on the wave wing module through the main shaft, so that the wave wing module generates an acting force opposite to the direction of the wave to weaken the swing of the column.

[0099] In a specific scene example, the control method and device of the fan integrated power generation system provided by the present specification can be applied, on the one hand, to realize the cooperative power generation of wave energy and wind energy in the fan integrated power generation system, and on the other hand, to form a target torque by using a controller under the action of a wave, and to feed the target torque to the wave wing module and the column structure through a main shaft, so as to effectively suppress the up-and-down floating and structural swinging of the platform under the action of a strong wave, improve the adaptability of the fan integrated power generation system to complex sea conditions, and enhance the stability of the platform operation and the reliability of the power generation system. The specific implementation process can include the following contents.

[0100] In some embodiments, when the SPAR type wind turbine moves up and down under the action of wave load, the water flow drives the wave wing to move, which in turn drives the power generation ring to rotate around the stand. According to the direction and intensity of the water flow, the wave wing hub can adjust the inclination angle of the wave wing, so that it is always in the most favorable force state to obtain the best rotation efficiency. When the wind turbine moves upwards with the platform, the power generation ring rotates clockwise; when the wind turbine moves downwards, the power generation ring rotates counterclockwise. This rotation process not only drives power generation, but also forms a reverse torque in the system, which helps to reduce the motion response of the wind turbine platform, reduce the amplitude of its movement in the waves, and improve the stability of the system. The power generation ring rotates simultaneously with the main bearing and main shaft connected thereto. The main shaft transmits the rotation energy to the gear box, which converts the low speed and high torque mechanical energy provided by the wave wing into high speed and low torque output, and drives the generator through the driven shaft to generate electricity. This process can efficiently convert wave energy into electrical energy and improve overall power generation efficiency.

[0101] Based on the above embodiments, the wave wing power generation ring can generate electricity using the energy of the waves. Through the wave wing, wave energy can be effectively converted into electrical energy, improving power generation efficiency. The wave wing can be self-adaptively adjusted according to the direction and intensity of the water flow, and whether the wind turbine moves upwards or downwards, the power generation ring can generate electricity by rotating clockwise or counterclockwise. This bidirectional motion design ensures that the wind turbine can continuously generate electricity during movement in different directions, improving energy utilization. This specification integrates the wind turbine and the wave wing module, and when the wind turbine moves upwards, the power generation ring rotates clockwise, and when the wind turbine moves downwards, the power generation ring rotates counterclockwise, forming a reverse torque that helps to reduce the motion response of the wind turbine, reduces the violent movement of the wind turbine in the waves, and improves its stability and durability. In addition, the integration of the wind turbine and the wave wing module shares the mooring, common maintenance, improves the wave energy device's ability to withstand waves, and reduces the cost of wave energy device power generation and the operation and maintenance cost of the wind farm. In this way, the motion response of the wind turbine can be reduced, the wave energy device's ability to withstand waves can be improved, the cost of wave energy device power generation and maintenance difficulty can be reduced, and the operation and maintenance cost of the wind farm can be reduced.

[0102] Although the specification provides method operations steps as examples or flowcharts, more or fewer operations steps can be included based on conventional or non-creative means. The order in which the steps are listed in the examples is only one of many possible execution sequences of the steps. In actual implementation, the device or client product can be executed according to the method sequence shown in the examples or in parallel (for example, in a parallel processor or multi-threaded processing environment, or even in a distributed data processing environment). The terms "include", "contain" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, product or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, product or equipment. Without more limitations, it does not exclude the presence of other same or equivalent elements in the process, method, product or equipment including the elements. The terms "first", "second" and the like are used to indicate names, not to indicate any particular order.

[0103] Those skilled in the art also know that, in addition to implementing the controller in the form of pure computer readable program code, the same function can be achieved by logically programming the method steps in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers and embedded microcontrollers. Therefore, such a controller can be considered as a hardware component, and the means included therein for implementing various functions can also be considered as structures within the hardware component. Alternatively, the means for implementing various functions can be considered as both software modules implementing the method and structures within the hardware component.

[0104] From the above description of the examples, those skilled in the art can clearly understand that the specification can be implemented by means of software and the necessary general hardware platform. Based on such understanding, the technical solutions of the specification can essentially be embodied in the form of a software product, which can be stored in a storage medium, such as ROM / RAM, magnetic disk, optical disk, etc., and includes a number of instructions for causing a computer device (which can be a personal computer, mobile terminal, server, or network device, etc.) to execute the method of each embodiment or some part of the embodiment of the specification.

[0105] Although the specification is described by the examples, those skilled in the art know that there are many modifications and changes to the specification without departing from the spirit of the specification, and it is intended that the appended claims include these modifications and changes without departing from the spirit of the specification.
