[0021] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The main solution of the embodiment of the present application is: based on the user's behavior data, calculate the user's behavior speed coefficient; obtain the scene speed coefficient of the simulation scene; calculate the real-time speed of the treadmill according to the scene speed coefficient and the behavior speed coefficient; control the treadmill to run based on the operating parameters corresponding to the real-time speed.

[0024] In the related art, virtual treadmills are usually set with different running speeds based on different simulated scenes. As the user runs, the virtual treadmill will gradually change the current simulated scene and adjust the running speed accordingly to improve the user's running training effect. However, in the actual running process, the virtual treadmill mainly relies on the single dimension of simulated scene changes to adjust the running speed, without considering factors such as physical fluctuations, state changes, and personal preferences that may occur during the running process of the user, thereby limiting the maximization of the treadmill training effect.

[0025] The present application obtains the user's motion information through a camera on the treadmill, and obtains the user's gait data through a foot sensor of the user, calculates a behavior speed coefficient, and calculates the running speed of the treadmill according to the behavior speed coefficient and the scene speed coefficient of the simulation scene, and controls the treadmill to run based on the running parameters corresponding to the running speed, so that the treadmill can adjust the actual running speed of the treadmill according to multiple dimensions such as the user's motion state and the current simulation scene, thereby improving the running training effect.

[0026] In order to better understand the above technical solution, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0027] It should be noted that the execution subject of this embodiment can be a treadmill control system, or a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a treadmill control device for scene simulation, etc., and this embodiment does not specifically limit this. The following takes the treadmill control system as an example to illustrate this embodiment and the following embodiments.

[0028] Based on this, the embodiment of the present application provides a treadmill control method for scene simulation, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the treadmill control method for simulating the scenario of this application.

[0029] In this embodiment, the treadmill control method for scene simulation includes steps S10 to S40: Step S10: determining the user's action information according to the image information collected by the camera device; In this embodiment, the treadmill control system is applied to the treadmill, and the treadmill can be controlled to perform corresponding scene simulation actions. The treadmill includes a display screen, at least one camera device and a treadmill. Among them, the display screen can be a visual display device such as a projection screen, a large LCD screen or a virtual reality (VR, Virtual Reality) display screen, which is used to display the visual picture of the treadmill simulation scene. It can be set in front of the treadmill on the treadmill, or it can be deployed around the user in a surround manner. The camera device is used to collect image information of the user's movement process, including a camera device set on the front of the treadmill, which can collect image information of the front of the user's movement, and can also include a camera device set on the side of the treadmill to fully understand the action information of the user's running process. The treadmill is used to run according to the running speed determined by the treadmill control system, so that the user can run based on the desired running speed.

[0030] For example, refer to Figure 2 , Figure 2 Schematic diagram of the treadmill structure involved in the embodiment of the present application. Figure 2 As shown, the treadmill includes a display screen, a treadmill control screen and a treadmill. The user can run on the tracks in the treadmill and simulate the running scene through the simulated scene displayed on the treadmill display screen. The display screen includes a camera to collect the user's motion information during exercise. The user can control the treadmill through body movements, voice, or by operating the treadmill control screen on the treadmill.

[0031] Specifically, when the treadmill control system receives the image information of the user collected by the treadmill through the camera device, it can use image recognition to identify the user's action information, wherein the action information may optionally include the user's body movement information and / or expression information.

[0032] In one embodiment, step S10 includes steps S11 to S13: Step S11: acquiring the image information captured by the camera device, and identifying the limbs and face areas of the user in the image information; In this embodiment, the treadmill control system obtains image information captured by the camera device, and identifies the image contour of the user in the image information through image segmentation and edge detection, and matches the image contour with preset information, and identifies the user's limb area and facial area based on the matching result.

[0033] Step S12: generating body movement information of the user according to the limb regions, and extracting expression information of the user in the facial region; In this embodiment, the treadmill control system can analyze the swing amplitude, swing position and swing frequency of the user's limbs according to the position changes of the limb area to generate limb movement information. At the same time, the treadmill control system can analyze the characteristics of facial expressions based on the user's facial area, such as the amplitude of the smile, the position of the eyebrows, the shape of the eyes, etc., to determine the degree of frowning or smiling of the user's facial expression and determine the user's expression information.

[0034] Step S13: Determine the action information based on the body movement information and the facial expression information.

[0035] In this embodiment, the motion information may include the user's body motion information and / or facial expression information. The treadmill control system may collect and organize the acquired body motion information and / or facial expression information to generate the user's motion information.

[0036] Exemplarily, the treadmill control system uses a camera or motion capture system to collect data in real time, and after receiving the collected video stream, it can determine the image frames in the video stream, the image information, and the depth information and motion trajectory of each point in the image information. After performing operations such as denoising and data cleaning, and determining the limb area and facial area through image segmentation, the treadmill control system analyzes the characteristics of the user's motion state, such as the step length, step frequency, and symmetry of the gait, the degree of smile and frown of facial expressions, and the swing amplitude and speed of limb movements, based on the depth information and motion trajectory of the pixel points of the image in the limb area and facial area.

[0037] Step S20: receiving gait data sent by the foot sensor, and calculating a behavior speed coefficient according to the gait data and the motion information; In this embodiment, the treadmill control system can wirelessly communicate with an external foot sensor via Bluetooth or other means to obtain gait data collected by the foot sensor. The foot sensor is installed on the user's foot and can detect changes in the movement of the user's foot during the user's exercise to form gait data.

[0038] Optionally, the foot sensor works based on the piezoresistive effect or other sensing principles. When the pressure of the foot is applied to the sensor, the resistance or other physical quantity inside the sensor is changed, which is converted into gait data in the form of an electrical signal for transmission and processing.

[0039] In a real-time manner, step S20 includes steps S21-S24: Step S21: analyzing the acceleration and angular velocity of the user based on the gait data; In this embodiment, the foot sensor may be an inertial measurement unit (IMU) sensor. The IMU sensor includes a gyroscope and an accelerometer. The accelerometer can collect the acceleration information of the foot, including the acceleration in the three directions of the x-axis, y-axis and z-axis. When the human body is walking or running, the acceleration of the foot will show periodic fluctuations. The accelerometer monitors this periodic change in real time, and calculates the gait and number of steps based on this periodic feature. The gyroscope monitors the angular velocity of the foot in real time during walking. The direction of the gyroscope's rotation axis does not change with the rotation of the foot. When the foot is affected by an external angle change, the capacitance between the upper and lower metals inside the gyroscope will change, so that the angle change can be judged based on the change in the voltage value.

[0040] Optionally, the treadmill control system can also use a camera to capture information such as the step length, step frequency, and symmetry of the gait to further improve the gait data. The treadmill control system can determine the step length and step frequency of the gait based on the swing amplitude and swing frequency of the user's legs through the image information collected by the camera on the side of the treadmill.

[0041] Step S22: and determining the user's movement amplitude according to the body movement information, and / or determining the user's emotional state according to the expression information; In this embodiment, the treadmill control system can determine the user's movement amplitude based on changes in the limb areas in the limb movement information, and analyze the user's emotional state based on the position and shape of the user's eyebrows and mouth corners in the expression information.

[0042] Step S23: determining the motion state of the user according to the acceleration and the angular velocity, as well as the motion amplitude and / or the emotional state; Step S24: Determine the behavior speed coefficient corresponding to the motion state.

[0043] In this embodiment, the treadmill control system can perform a comprehensive evaluation based on the analysis results of gait data, expression information and limb movement information, and obtain a comprehensive exercise status score by considering the weights and correlations between different features.

[0044] Optionally, the gait characteristics can be compared with historical data or a standard gait database to determine whether the gait is stable and normal. According to the changes in gait characteristics, such as a decrease in step length and an increase in step frequency, the user's fatigue level or exercise intensity can be evaluated. At the same time, the coordination, fluency and amplitude of limb movements can be analyzed to evaluate the user's exercise effect and physical condition. If there are abnormalities in limb movements, such as a decrease in swing amplitude and a slowdown in speed, the treadmill can also be adjusted. In addition, a facial recognition algorithm is used to monitor the user's facial expressions. The user's emotional state can be evaluated by analyzing the characteristics of facial expressions, such as the amplitude of the smile, the position of the eyebrows, the shape of the eyes, etc. If the user shows obvious fatigue or discomfort, the treadmill can be triggered to slow down or stop.

[0045] Optionally, the treadmill control system can also train the behavior speed calculation model based on deep learning to determine the behavior speed coefficient. The treadmill control system will train and optimize the behavior speed calculation model based on historical motion information and gait data using deep learning. And the collected motion information and gait data are input into the trained behavior speed calculation model. Among them, the behavior speed calculation model contains evaluation functions of multiple dimensions such as acceleration, angular velocity, motion amplitude, emotional state, etc. After evaluating the data of different dimensions respectively, weighted calculation can be performed according to the evaluation results, and the behavior speed coefficient can be determined according to the calculation results.

[0046] Step S30: calculating the running speed of the treadmill according to the scene speed coefficient of the simulation scene and the behavior speed coefficient; Step S40: controlling the treadmill to run based on the running parameters corresponding to the running speed.

[0047] In this embodiment, the treadmill control system can calculate the user's expected running speed based on the scene speed coefficient and the behavior speed coefficient, and use the expected running speed as the running speed of the treadmill. The treadmill control system can adjust the speed of the treadmill based on the running speed, that is, control the treadmill to run based on the running parameters corresponding to the running speed.

[0048] Optionally, corresponding to the way in which the treadmill control system calculates the behavior speed coefficient, the treadmill control system can calculate the behavior speed coefficient by multiplying the scene speed coefficient and the behavior speed coefficient with the initial speed, or can calculate the behavior speed coefficient by weighted summing the scene speed coefficient, the behavior speed coefficient and the initial speed.

[0049] The embodiment of the present application obtains the user's motion information through a camera on the treadmill, and obtains the user's gait data through a foot sensor of the user, calculates a behavior speed coefficient, and calculates the running speed of the treadmill according to the behavior speed coefficient and the scene speed coefficient of the simulation scene, and controls the treadmill to run based on the running parameters corresponding to the running speed, so that the treadmill can adjust the actual running speed of the treadmill according to multiple dimensions such as the user's motion state and the current simulation scene, thereby improving the running training effect.

[0050] Based on the same inventive concept, the present application also provides a second embodiment, referring to Figure 3 , Figure 3 This is a flow chart of the second embodiment of the treadmill control method for simulating the scenario of this application.

[0051] In this embodiment, before calculating the running speed of the treadmill according to the scene speed coefficient of the simulation scene and the behavior speed coefficient as described in step S30, steps S31 to S33 are also included: Step S31: acquiring a scene description text, and determining a scene speed coefficient of the simulation scene according to the scene description text; In this embodiment, the treadmill control system can receive the scene description text input by the user and generate a corresponding simulation scene. After receiving the scene description text, the treadmill control system can determine the scene elements and the running type in the scene description text, and determine the scene speed coefficient of the simulation scene corresponding to the scene description text according to the scene elements and the running type.

[0052] In one embodiment, the treadmill control system identifies scene information and multiple event information in the scene description text. The treadmill control system can directly generate a scene speed coefficient based on the scene information, or can generate scene speed coefficients under different events based on the scene information and the event information. The scene information is the scene of the user running in the simulated scene, and the event information is the event encountered by the user during the running process in the simulated scene. According to the scene description text and the scene information, the scene speed coefficient corresponding to each event information is determined.

[0053] Optionally, the user can output the scene description text through text input, or can orally describe a description. The treadmill control system can generate the scene description text based on the user's oral information through a large language model such as ChatGPT.

[0054] Optionally, the treadmill control system can also generate a scene speed calculation model based on deep learning, and input the scene description text or event information into the trained scene speed calculation model. The scene speed calculation model includes a scene speed function, which can generate a scene speed coefficient based on the scene description text or event information.

[0055] Step S32: generating a scene simulation video of the simulated scene based on the scene description text and the scene speed coefficient; In this embodiment, the treadmill control system can generate a scene simulation video of the simulated scene based on the Vincent video model, the scene description text, and the scene speed coefficient. The generated scene simulation video can be selected as a VR video or an ordinary video. The scene simulation video will be generated by giving the scene speed coefficient a way of advancing in the simulated scene.

[0056] Specifically, the treadmill control system can generate an event simulation video of the event information occurring in the scene information based on the scene speed coefficient of the event information, and generate a scene simulation video by connecting the event simulation videos.

[0057] Exemplarily, the treadmill control system determines that the scene information is the school playground track based on "the user running around the track on the school playground", and based on the scene description text generated by the large language model, determines that there are times when the user runs in a straight line and in a curve during the running process, and generates an event simulation video of the corresponding running event, and connects the event simulation videos to generate a complete scene simulation video.

[0058] Optionally, the scene description text may contain branch events, and the treadmill control system may also connect event simulation videos based on a tree diagram to trigger different branch events according to different user behaviors. For example, when encountering a road fork, the treadmill can detect the user's angular velocity based on the IMU sensor and determine the user's running direction to trigger different event simulation videos.

[0059] Optionally, the treadmill control system retrieves pre-stored pictures or videos and other information in the user database through retrieval-augmented generation (RAG) to generate a scene more suitable for the user. For example, the user can import video information shot in a park near his home into the user database, and the treadmill control system can generate a simulated scene of running in the park based on the video information.

[0060] Step S33: displaying the scene simulation video on the treadmill display screen.

[0061] In this embodiment, after generating the scene simulation video, the treadmill control system can control the treadmill display screen to output the scene simulation video in a quasi-real-time manner. Alternatively, the treadmill control system can also associate the scene simulation video with the scene description text and / or keywords in the scene description text and save it, and output the scene simulation video on the treadmill display screen based on the user's selection.

[0062] In one example, when the treadmill control system obtains the user's motion information and determines that the running speed of the treadmill needs to be adjusted, it can adjust the running speed of the simulated scene perceived by the user by controlling the video playback speed or changing the scene simulation video, so that the simulated scene perceived by the user visually matches the running speed of the treadmill. For example, when the user gradually reduces the running speed, the treadmill control system can slow down the video playback speed so that the user can visually synchronize the feeling of the treadmill reducing the running speed, or the treadmill control system can also switch the scene simulation video based on the branch of the scene simulation video to achieve the effect of dynamically adjusting the scene simulation video based on the running speed.

[0063] In an embodiment of the present application, the treadmill control system can generate a simulation scene and a corresponding scene simulation video based on a user description or a scene description text, thereby expanding the richness of the scenes that can be simulated by the treadmill and realizing the personalization of the simulation scenes.

[0064] Since the system introduced in the second embodiment of the present application is a system used to implement the method of the first embodiment of the present application, based on the method introduced in the first embodiment of the present application, the person skilled in the art can understand the specific structure and deformation of the system, so it is not repeated here. All systems used in the method of the first embodiment of the present application belong to the scope of protection of this application.

[0065] Based on the same inventive concept, the present application also provides a third embodiment, referring to Figure 4 , Figure 4 This is a flow chart of the third embodiment of the treadmill control method for simulating the scenario of this application.

[0066] In this embodiment, the treadmill control method of the scene simulation includes steps S34 to S37: Step S34: after receiving the scene adjustment instruction, pausing the scene simulation video on the treadmill display screen; Step S35: receiving the user's voice description information, and comparing the voice description information with the simulation scenario; Step S36: determining scene adjustment information according to the difference information between the voice description information and the simulation scene in the comparison result; Step S37: adjusting the scene simulation video based on the scene adjustment information.

[0067] In this embodiment, when the user finds that the simulation scene does not meet expectations during running, the user can trigger the scene adjustment process of the treadmill control system by voice or by clicking the scene adjustment button on the treadmill control screen. For example, the user can trigger the scene adjustment by pre-set scene adjustment instructions such as "pause" or "scene adjustment", and input the content to be adjusted into the treadmill control system. The treadmill control system can receive voice description information through the microphone device of the treadmill, and / or obtain the data such as pictures and videos inserted by the user, and compare it with the current simulation scene, determine the difference information to determine the content of the simulation scene that needs to be adjusted, and generate scene adjustment information.

[0068] In one embodiment, the treadmill control system can simulate the corresponding running scene based on the running route given by the user in the map. The treadmill control system can obtain the scene information and distance information on the map based on the satellite navigation system and / or the map system to realize the corresponding scene simulation. When the user finds that the simulated scene does not match the actual scene during the running process, the simulated scene can be adjusted through the scene adjustment.

[0069] For example, when the simulated scene is a sidewalk, the user can click the scene adjustment button on the treadmill control screen to pause the current running and scene simulation, and input "the left side of the sidewalk lacks a green belt" by voice, and insert an actual sidewalk picture. The treadmill control system can adjust the left side of the sidewalk in the simulated scene based on the sidewalk picture and keywords such as "left side of the sidewalk" and "green belt" in the voice information to generate a green belt.

[0070] The embodiment of the present application improves the accuracy of simulation information of the simulated scene by receiving scene adjustment information from the user and modifying the scene information in the simulated scene.

[0071] Since the system introduced in the third embodiment of the present application is a system used to implement the method of the first embodiment of the present application, based on the method introduced in the first embodiment of the present application, the person skilled in the art can understand the specific structure and deformation of the system, so it is not repeated here. All systems used in the method of the first embodiment of the present application belong to the scope of protection of the present application.

[0072] Based on the same inventive concept, the present application also provides a fourth embodiment, referring to Figure 5 , Figure 5 This is a flow chart of the fourth embodiment of the treadmill control method for simulating the scenario of the present application.

[0073] In this embodiment, the treadmill control method for scene simulation further includes steps S50 to S52: Step S50: when the running progress of the user reaches the prompt triggering position of the simulation scene, outputting corresponding position prompt information; Step S51: receiving description information based on the location prompt information, and determining scene information and distance information of the description information; Step S52: Based on the scene information and the distance information, generate the scene simulation video of the next simulation scene.

[0074] In this embodiment, the user can also interact with the treadmill in real time to generate simulation scenes and scene simulation videos in real time during the running process. The treadmill control system is based on the simulation scene. Whenever the user reaches a certain node of the simulation scene, that is, the prompt trigger position, the treadmill control system will display the position prompt information on the display screen, or output the position prompt information in the form of voice broadcast. The user can describe the content of the next simulation scene or the next simulation event based on the current position in the position prompt information, and output the description information.

[0075] Specifically, the treadmill control system can determine the distance information and scene information of the next simulation scene based on the description information. For example, the user can say "the park entrance is one hundred meters ahead" during running, and the treadmill control system can determine that the distance information is 100 meters ahead and the scene information is the park intersection. The user can continue to say "the park contains a forest, and the length of the forest is 500 meters", and the treadmill control system will generate a simulation scene of a park forest with a distance of 500 meters.

[0076] Optionally, the treadmill control system can further compare the simulation scene with a preset simulation scene in the system to determine a scene speed coefficient, and synchronously calculate the running speed and adjust the running parameters based on the scene speed coefficient and the user's current motion information and gait data.

[0077] Optionally, the user can adjust the simulation scene through the scene adjustment command during the running process of the simulation scene generated in real time. At the same time, the treadmill control system will also record the simulation scene generated during the running process, and confirm to the user on the display screen whether to save the simulation scene.

[0078] The embodiment of the present application generates a running simulation scene in a quasi-real-time manner through the user's voice input, and can generate a simulation scene that better meets the user's expectations based on the user's needs, thereby improving the realism of the simulation scene.

[0079] Since the system introduced in the fourth embodiment of the present application is a system used to implement the method of the first embodiment of the present application, based on the method introduced in the first embodiment of the present application, the person skilled in the art can understand the specific structure and deformation of the system, so it is not repeated here. All systems used in the method of the first embodiment of the present application belong to the scope of protection of this application.

[0080] Based on the same inventive concept, the present application also provides a fifth embodiment, referring to Figure 6 , Figure 6 This is a flow chart of the fifth embodiment of the treadmill control method for simulating the scenario of the present application.

[0081] In this embodiment, the treadmill control of the scene simulation includes steps S60 to S62: Step S60: receiving sensing information transmitted by the foot sensor, and determining user identity information corresponding to the sensing information; Step S61: reading gait assessment data in the sensor information, evaluating the gait assessment data, and generating gait assessment information corresponding to the user identity information; Step S62: when triggering the scene simulation process, determining the initial speed of the user according to the gait evaluation information corresponding to the user identity information; Step S63: acquiring initial operating parameters corresponding to the initial speed, and controlling the treadmill to operate based on the initial operating parameters.

[0082] In this embodiment, before the user starts running, the treadmill control system will obtain the gait assessment data of the user for assessing the gait condition through the foot sensor, and analyze it to generate gait assessment information. At the same time, the treadmill control system will associate the gait assessment information with the user's identity information and save it to help fully understand the user's condition during the running process.

[0083] Specifically, the treadmill control system can record the data collected by the foot sensor. The collected data usually includes the acceleration and angular velocity in the three directions of the x-axis, y-axis, and z-axis, as well as possible data information of attitude angles such as roll angle, pitch angle, yaw angle, etc. By evaluating the stability, symmetry, efficiency, etc. of the user's gait based on the extracted gait features. By obtaining the user's gait data from the foot sensor and evaluating it, and associating the gait evaluation information with the user's identity information, the user's training effect and applicable training methods can be understood in a timely manner.

[0084] Furthermore, based on the user's identity information, the treadmill control system can obtain the corresponding gait evaluation information and determine the appropriate initial operating parameters for the user when he or she gets on the treadmill. The treadmill control system can use the same analysis method as the gait data in the process of calculating the behavioral speed coefficient to determine the initial speed based on the gait evaluation information. The treadmill control system will control the treadmill in the treadmill to run with the initial operating parameters corresponding to the initial speed. Among them, the treadmill control system can collect the user's facial information through a camera device, perform facial recognition, and determine the user's identity information. It can also determine the user's identity information by voice recognition and determining the user's timbre, or it can determine the user's identity information based on the user's gait information based on the gait characteristics of the human body.

[0085] The embodiment of the present application determines the initial speed of response based on the gait assessment information corresponding to the user identity information, so as to help the user start training in a gradually adaptive manner and improve the training effect.

[0086] Since the system introduced in the fifth embodiment of the present application is a system used to implement the method of the first embodiment of the present application, based on the method introduced in the first embodiment of the present application, the person skilled in the art can understand the specific structure and deformation of the system, so it is not repeated here. All systems used in the method of the first embodiment of the present application belong to the scope of protection of the present application.

[0087] Based on the same inventive concept, the present application also provides a sixth embodiment, referring to Figure 7 , Figure 7 This is a flow chart of the sixth embodiment of the treadmill control method for simulating the scenario of the present application.

[0088] In this embodiment, the treadmill control of the scene simulation includes steps S70 to S72: Step S70: Acquire the user's body movement information in the behavior data; Step S71: determining target interaction information matching the body movement information in the interaction information of the simulated scene; Step S72: determining a target running speed of the treadmill and an interactive action of the simulation scene based on the target interaction information; Step S73: executing the interactive action, and controlling the treadmill to run based on the target running parameters corresponding to the target running speed.

[0089] In this embodiment, based on the scene simulation video and the event simulation video in the scene simulation video, the treadmill control system can interact with the user based on the user's motion information obtained by the camera device.

[0090] In one example, based on scene interaction, the scene simulation of the treadmill can improve the realism of the scene simulation, or achieve the treatment of autistic patients through simulation. For example, when the front interactive page is approaching the store entrance, the user can freely trigger to enter the store, and the scene switching treadmill speed will also decrease; when walking to the ice cream shop stall, the treadmill control system will trigger the treadmill to stop, and the front screen can prompt whether to buy, and the user can interact with the treadmill through gestures to get the goods, etc. During walking, the system can adjust the speed according to the scene and user behavior.

[0091] In another example, the treadmill control system may also be based on a relay race scenario. When the user triggers a relay event, the running event is triggered by the action of taking the baton, and the treadmill control system controls the treadmill to start accelerating.

[0092] In an embodiment of the present application, the treadmill control system can interact with the user based on the detected user movements to enhance the user's sense of reality during the running process, or assist the recovery of autistic patients and improve the patient's acceptance of the outside world through scene simulation.

[0093] Since the system introduced in the sixth embodiment of the present application is a system used to implement the method of the first embodiment of the present application, based on the method introduced in the first embodiment of the present application, the person skilled in the art can understand the specific structure and deformation of the system, so it is not repeated here.
