[0009] Preferably, the rhythm monitoring module, in the wind power project operation execution process, real-time collects positioning data and operation data of the target operation personnel, constructs an operation rhythm curve, evaluates the fatigue state of each target operation personnel, triggers a recovery instruction and automatically adjusts the task division, specifically: In the wind power project operation execution process, real-time collects positioning data and operation data of the target operation personnel, the operation data includes personnel physiological data and operation time data; Based on the operation data, an operation rhythm curve of the target operation personnel is constructed, and the operation rhythm curve is used to reflect the continuous operation intensity and fatigue state trend of the target operation personnel; According to the operation rhythm curve, the fatigue state of each target operation personnel is evaluated, when the operation rhythm curve reaches a set fatigue critical threshold, a recovery instruction is triggered, and the operation task of the personnel is forced to pause; At the same time, the task division is automatically adjusted, the remaining operation task of the personnel is transferred to the non-over-limit personnel, and the remaining operation task is continued according to the positioning data.

[0010] Preferably, the abnormality processing module, when a sudden event is monitored, automatically calls a preset abnormal scene template, according to the preset emergency response process and set role division requirement of the abnormal scene template, automatically distributes an emergency task instruction and executes the steps, specifically: When a sudden event is monitored, an emergency response is triggered, a preset abnormal scene template is automatically called, the abnormal scene template includes personnel falling into water, ship deviation or equipment failure abnormal scene and its emergency response process and role division requirement; The role division requirement in the abnormal scene template is compared with the role cooperation quota control result, if there is a gap role, a role replacement signal is automatically triggered, and the available target operation personnel on site is dynamically allocated to the gap role; And according to the emergency response process in the abnormal scene template, an emergency task instruction is automatically distributed and executed.

[0013] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the multi-dimensional fusion of risk integration account, role collaboration quota, operation rhythm monitoring, abnormal scene emergency template and closed-loop safety index feedback mechanism, the dynamic safety management and control of personnel and ships throughout the life cycle is realized. The sea access control is carried out through the integral threshold, which effectively avoids the personnel or ships without safety conditions entering the offshore operation scene, and reduces the potential safety hidden danger from the source. The wind power project operation area is divided into multiple sub-areas, and the role collaboration quota is set according to the operation task characteristics of different sub-areas, which can realize the structured scheduling of human resources, avoid the vacancy or redundancy problem caused by random allocation of personnel, and ensure that each operation unit has the necessary safety monitoring, operation execution and emergency rescue roles; combined with the sea approval list, the limited qualified personnel can be reasonably allocated to key positions, improving the organization and safety redundancy of the whole operation. In the operation process, the positioning and operation data of personnel are collected in real time, and the operation rhythm curve is constructed, which can accurately reflect the work load and fatigue state of personnel. Through the dynamic evaluation of fatigue index, the system can automatically trigger the rest instruction when the personnel state approaches the dangerous critical point, and automatically adjust the task division, which not only ensures the health and safety of individual operation personnel, but also maintains the continuity of the overall operation efficiency through intelligent scheduling, avoiding the spread of group risk caused by individual mistakes. When an emergency occurs, the abnormal scene template corresponding to the event type is automatically called, the role division requirements in the template are matched with the actual on-duty personnel, the emergency task instruction is automatically generated and sent to the execution terminal, the rapid, accurate and clear division of emergency response is realized, and the speed and execution force of emergency response are significantly improved, thereby minimizing the loss and risk in high-risk scenarios such as personnel falling into the water and equipment failure. After the operation is completed, the closed-loop safety index is calculated by comprehensively analyzing the process risk warning, abnormal disposal effect and back to port personnel result, and fed back to the risk integration account, realizing the closed-loop tracing mode of post-task evaluation-risk integration dynamic update-next task access adjustment. Not only can the safety performance of personnel and ships be supervised for a long time, but also the adaptability and robustness of the whole system can be continuously improved through dynamic optimization of integral rules and management parameters, so as to form a sustainable safety management and control system.

[0014] 2. The entire wind power operation area is divided into multiple sub-areas, which can realize fine management of space, and each sub-area corresponds to a specific operation task, which is convenient for orderly scheduling of task resources, personnel and equipment. The electronic fence can monitor the entry and exit of personnel and ships in real time, realize space boundary management, reduce the risk of personnel entering dangerous areas by mistake, and improve the visualization and accuracy of safety control. According to the task type and task complexity, configure the required role collaboration quota for each sub-area, including the number of guardians, operators and rescue personnel, to ensure that each sub-area operation has enough personnel and role division of labor, prevent accidents caused by insufficient personnel, and also avoid excessive personnel causing resource waste or congestion hazards, achieving a balance between operation safety and efficiency. Through an automatic matching mechanism, personnel are assigned to their respective posts to ensure that each role meets the minimum safety standard. If there is a shortage of personnel in key positions, the system calls qualified personnel from the sea candidate list to supplement, avoiding operation risks caused by personnel gaps, achieving dynamic scheduling and safety redundancy, and being able to adapt to temporary changes in personnel, sudden leave or task adjustment, ensuring the continuity and safety of each sub-area operation. By setting a maximum number of people in each sub-area, overcrowding, operational interference or safety passage blockage caused by too many people can be prevented, ensuring smooth emergency evacuation and emergency response. Comparing the role collaboration quota with the upper limit of the number of people can ensure that the sub-area space capacity is not overloaded on the premise of meeting the operation safety and role division of labor, achieving a dynamic balance between the number of personnel and safety boundaries. When the role quota demand and space capacity conflict, the system triggers an over-limit warning and optimizes the scheduling scheme, such as adjusting the operation sequence, delaying part of the operation or reallocating roles, effectively preventing excessive clustering from causing safety risks, while ensuring that critical roles for each task are protected, achieving dual optimization of operation safety and efficiency.

[0015] 3. The number of trimming instructions reflects the fatigue management of the workers, and the number of emergency responses reflects the handling of emergencies. In combination with the generated process risk warning data, the potential safety risks in the operation process can be comprehensively evaluated. The emergency task completion rate and the response degree reflect the timeliness and effectiveness of the handling of emergencies. In combination with the generated abnormal disposal effect data, the safety performance of the target workers and the ship in the emergency can be measured, and the closed-loop safety index can be used to comprehensively evaluate the process and result of the operation safety management. The closed-loop safety index is generated by weightedly analyzing the risk intervention, abnormal disposal effect and back-to-port personnel data in the operation process. The index can not only reflect the safety management level of the operation process, but also reflect the safety closed-loop state after the operation. A high safety index indicates that the workers and the ship perform well in the entire operation cycle, and the risk control is in place. The risk points can be reduced as an incentive mechanism to encourage safe operation, establish positive feedback, and promote the workers and the ship to maintain safe behavior in subsequent tasks. A low safety index indicates that there are risk events or poor intervention effects during the operation, and the risk points are increased and marked as key risk objects, which can remind the managers to control the high-risk workers or ships, limit their participation in subsequent high-risk operations, and form a dynamic safety tracing mechanism. This step realizes risk closed-loop management and ensures that the safety management system is sustainable and dynamically adjustable. BRIEF DESCRIPTION OF DRAWINGS

[0019] The present application will be further described in detail below in conjunction with the embodiments and Figs. 1-2 The embodiments of the present application are not limited to this.

[0020] The present application discloses a safety management system for offshore wind power project workers, specifically including the following steps: The risk point module 1 establishes a risk point account for each target worker and target operation ship, and according to the risk point result, confirms the approval list for going to sea; The regional quota module 2 divides the wind power project operation area into multiple sub-areas, sets role cooperation quotas for each sub-area according to the target operation tasks of each sub-area, and performs role matching control on the target operation personnel in the sea approval list; The rhythm monitoring module 3 collects positioning data and operation data of the target operation personnel in real time during the execution of the wind power project operation, constructs an operation rhythm curve, evaluates the fatigue state of each target operation personnel, triggers a recovery instruction, and automatically adjusts the task division; The abnormality processing module 4 automatically calls a preset abnormality scene template when a sudden event is monitored, automatically allocates an emergency task instruction and issues an execution according to a preset emergency response process and a set role division requirement of the abnormality scene template; The closed-loop safety module 5 calculates a closed-loop safety index of the target operation after the target operation is completed, feeds back the closed-loop safety index to a risk integration account, and forms a dynamically updated safety backtracking mechanism.

[0021] In actual application, by establishing independent risk score accounts for each target worker and ship, dynamic risk assessment based on historical data and current state is realized, key safety factors such as personnel health status, violation record, and ship maintenance status can be quantified and presented in the form of risk score, thereby realizing traceable safety credit management. By setting an integral threshold for sea access control, personnel or ships without safety conditions can be effectively prevented from entering the offshore work scene, thereby reducing potential safety hazards from the source. The work area of a wind power project is divided into multiple sub-areas, and role collaboration quotas are set according to the task characteristics of different sub-areas, so as to realize the structured scheduling of human resources and avoid the problems of vacancy or redundancy caused by random allocation of personnel, thereby ensuring that each work unit has the necessary safety monitoring, operation execution, and emergency rescue roles; in combination with the sea approval list, qualified personnel can be reasonably allocated to key positions, thereby improving the organization and safety redundancy of the overall operation. In the operation process, the positioning and operation data of personnel are collected in real time, and an operation rhythm curve is constructed, which can accurately reflect the work load and fatigue state of personnel. Through dynamic evaluation of the fatigue index, the system can automatically trigger a rest instruction when the personnel state approaches the dangerous critical point, and automatically adjust the task division, which not only ensures the health and safety of individual workers, but also maintains the continuity of overall operation efficiency through intelligent scheduling, thereby avoiding the spread of group risk caused by individual mistakes. When an emergency occurs, the abnormal scene template corresponding to the event type is automatically called, the role division requirements in the template are matched with the actual on-duty personnel, emergency task instructions are automatically generated and sent to the execution terminal, and rapid, accurate, and clear emergency response is realized. This method avoids the confusion and delay under traditional manual command, and can significantly improve the speed and execution of emergency response, thereby minimizing losses and risks in high-risk scenarios such as personnel falling into the water and equipment failure. After the operation is completed, the closed-loop safety index is calculated by comprehensively analyzing the process risk warning, abnormal disposal effect, and return personnel results, and is fed back to the risk score account, thereby realizing the closed-loop tracing mode of post-task evaluation-risk score dynamic updating-next task access adjustment. Not only can the safety performance of personnel and ships be supervised for a long time, but also the adaptability and robustness of the overall system can be continuously improved through dynamic optimization of integral rules and management parameters, thereby forming a sustainable safety management system.

[0022] The risk score module 1 establishes a risk score account for each target worker and target work ship, and confirms the sea approval list according to the risk score result, which specifically comprises: obtaining the work frequency, health data, and historical violation times of the target worker, establishing a risk score account for the target worker, and calculating the personnel risk score value; Obtaining the navigation record and safety maintenance data of the target work vessel, establishing a risk score account of the target work vessel, and calculating the risk score value of the vessel; Comparing the personnel risk score value and the vessel risk score value with preset personnel risk stage thresholds and vessel risk stage thresholds to obtain the risk levels of the personnel and the vessel; Based on the risk levels of the personnel and the vessel, confirming a list of personnel and vessels approved for going to sea.

[0023] In actual application, a dynamic risk score account is established by quantitatively counting and calculating the daily work frequency, physical health status and past violation behaviors of the personnel, so as to objectively reflect the comprehensive risk level of each working personnel and avoid relying on subjective experience for judgment, thereby controlling human risk from the source. The risk account of the vessel is established by quantitatively evaluating the navigation history and maintenance of the vessel. When the vessel has a high navigation frequency, is not timely maintained or has a history of accident hazards, the risk score value of the vessel will be high, so that the vessel is restricted in the approval link, ensuring that the vessel going to sea is safe and reliable in equipment state, and avoiding safety incidents caused by mechanical failure or hidden dangers. By setting reasonable risk thresholds, the risk score results are divided into different levels (such as low risk, controllable risk and high risk), so as to intuitively reflect the safety state of the personnel and the vessel. Through comprehensive judgment of the risk levels, a list of personnel and vessels approved for going to sea is finally generated after strict screening, thereby ensuring the double safety lines of personnel and equipment and reducing the accident rate. At the same time, the list is transparent and traceable, providing a basis for post-supervision and responsibility definition.

[0024] The step of confirming a list of personnel and vessels approved for going to sea based on the risk levels of the personnel and the vessel, specifically comprises: The risk levels of the personnel and the vessel include high risk level, medium risk level and low risk level; The personnel and vessels of high risk level are restricted from going to sea; The personnel and vessels of medium risk level are marked as a list of candidates for going to sea, and need to be additionally reviewed and are pending going to sea; The personnel and vessels of low risk level are marked as a list of personnel and vessels approved for going to sea, and are allowed to go to sea.

[0025] In actual application, high-risk level means that the personnel has serious health risks, frequent violation records, or the ship has major equipment defects, overdue maintenance, etc. If such objects are still allowed to go to sea, it will greatly increase the probability of accidents. By strictly limiting the high-risk objects to go to sea, the occurrence of personnel injury, equipment damage and group accidents can be avoided, which is the first line of defense to ensure overall safety. Medium-risk level means that the personnel or ship has certain risks, but has not reached the level of prohibiting going to sea, for example, the personnel has mild health abnormalities or occasional violations, and the ship has slight equipment wear or maintenance period close to the critical value. Through additional review (such as on-site physical examination, expert review, temporary maintenance), it is further judged whether it can be temporarily released, which not only avoids the waste of resources of one-size-fits-all, but also maintains the operation progress in the case of controllable risk, and balances safety and task execution efficiency. Low-risk level means that the personnel has good health, few or no violation records, and the ship is maintained in time and the equipment is in good condition. By preferentially selecting low-risk personnel and ships, the uncertainty of operation can be minimized, a robust and safe operation team and transportation system can be built, and the wind power project task can be completed smoothly.

[0026] The regional quota module 2 divides the wind power project operation area into multiple sub-areas, sets role cooperation quotas for each sub-area according to the target operation tasks of each sub-area, and performs role matching control on the target operation personnel in the sea approval list. The steps are as follows: In the wind power project operation area, multiple sub-areas are divided based on electronic fences, and the target operation tasks of each sub-area are determined; The task type and task complexity of each sub-area target operation task are obtained, and based on the task type and task complexity, the role cooperation quota required by each sub-area is determined, including the number of guardians, the data of operators, and the number of rescue personnel; The target operation personnel in the sea approval list are matched with roles, and if the number of personnel in a certain role is insufficient, a supplementary dispatch process is automatically triggered to call qualified personnel from the sea candidate list for supplementation until the role cooperation quota condition is met; The maximum number of simultaneous operation personnel allowed in each sub-area is obtained, and when the target operation personnel enter the sub-area, the role cooperation quota required by the sub-area is compared with the maximum number of simultaneous operation personnel; If the role cooperation quota required by the sub-area exceeds the maximum number of simultaneous operation personnel, a personnel over-limit warning is triggered, and the role cooperation quota of the sub-area is optimized and controlled.

[0027] In actual application, the entire wind power operation area is divided into multiple sub-areas, which can realize fine management of space, and each sub-area corresponds to a specific operation task, such as wind turbine maintenance, submarine cable laying or booster station maintenance, which facilitates the orderly scheduling of task resources, personnel and equipment. The electronic fence can monitor the entry and exit of personnel and ships in real time, realize space boundary management, reduce the risk of personnel entering dangerous areas by mistake, and improve the visualization and accuracy of safety control. According to the type of task (such as operation, monitoring, rescue) and the complexity of the task (such as single-person completion, multi-step complex operation), the required role collaboration quota for each sub-area is configured, including the number of guardians, operators and rescue personnel, to ensure that each sub-area operation has enough personnel and role division, prevent accidents caused by insufficient personnel, and also avoid excessive personnel causing resource waste or congestion hazards, achieving a balance between operation safety and efficiency. Through an automatic matching mechanism, personnel are assigned to their respective posts to ensure that each role meets the minimum safety standard. If there is a shortage of personnel in a critical position, the system calls qualified personnel from the sea candidate list to supplement them, avoiding operation risks caused by personnel gaps and achieving dynamic scheduling and safety redundancy. It can adapt to temporary changes in personnel, sudden leave or task adjustment, ensuring the continuity and safety of each sub-area operation. By setting a maximum number of people in each sub-area, overcrowding, operation interference or safety passage blockage caused by too many people can be prevented, ensuring smooth emergency evacuation and emergency response. Comparing the role collaboration quota with the upper limit of the number of people can ensure that the sub-area space capacity is not overloaded while meeting the operation safety and role division requirements, achieving a dynamic balance between the number of personnel and safety boundaries. When the role quota requirement conflicts with the space capacity, the system triggers an over-limit warning and optimizes the scheduling plan, such as adjusting the operation sequence, delaying part of the operation or reallocating roles, effectively preventing safety risks caused by excessive clustering while ensuring that critical roles for each task are protected, achieving dual optimization of operation safety and efficiency.

[0028] The rhythm monitoring module 3, in the process of executing the wind power project operation, collects the positioning data and operation data of the target operation personnel in real time, constructs an operation rhythm curve, evaluates the fatigue state of each target operation personnel, triggers a recovery instruction and automatically adjusts the steps of task division, specifically: In the process of executing the wind power project operation, the positioning data and operation data of the target operation personnel are collected in real time, and the operation data includes personnel physiological data and operation duration data; Based on the operation data, an operation rhythm curve of the target operation personnel is constructed, and the operation rhythm curve is used to reflect the continuous operation intensity and fatigue state trend of the target operation personnel; According to the operation rhythm curve, the fatigue state of each target operation personnel is evaluated, and when the operation rhythm curve reaches a set fatigue critical threshold, a recovery instruction is triggered to forcibly suspend the operation task of the personnel; Meanwhile, the task distribution is automatically adjusted, and the remaining work task of the personnel is transferred to the personnel not exceeding the limit, and according to the positioning data, the remaining work task is continued to be completed.

[0029] In actual application, the positioning data and the work data are collected in real time. The positioning data can determine the specific position of each work personnel in the sub-area, and ensure that the work distribution meets the safety plan. The work data (including physiological data such as heart rate, blood pressure, fatigue index, and work duration) can quantify the physical load and continuous work of the personnel. Through real-time collection of these information, dynamic monitoring is realized, and potential fatigue risk and work abnormalities are found in time. The work rhythm curve visualizes the continuous work intensity and fatigue state trend by analyzing the work data. The curve can identify the work peak, rest interval and fatigue accumulation of the personnel, and can predict potential risks to prevent operation errors or accidents caused by overwork. Through real-time analysis of the work rhythm curve, the fatigue state of each work personnel is judged. When the work intensity or physiological index reaches the set fatigue threshold, a rest instruction is automatically triggered to force the work task of the personnel to be paused, ensuring human safety and effectively avoiding operation errors, high-altitude falls or operation errors caused by fatigue, and forming a scientific work intensity control mechanism. In the case of work personnel pause, according to the real-time positioning and work task data, the remaining work task of the personnel is automatically allocated to the personnel not exceeding the limit to ensure continuous execution of the work task and not delay the construction period, realizing the balance between safety and efficiency, protecting the health of individuals and ensuring the overall work progress.

[0030] The abnormality processing module 4 automatically calls a preset abnormal scene template when a sudden event is monitored, automatically allocates emergency task instructions and issues execution according to the preset emergency response process and set role distribution requirements of the abnormal scene template, and the steps are as follows: When a sudden event is monitored, an emergency response is triggered, a preset abnormal scene template is automatically called, the abnormal scene template includes personnel falling into water, ship deviation or equipment failure abnormal scene and its emergency response process and role distribution requirements; The role distribution requirements in the abnormal scene template are compared with the role cooperation quota control result. If there is a gap role, a role replacement signal is automatically triggered, and the available target work personnel on site is dynamically allocated to the gap role. And according to the emergency response process in the abnormal scene template, emergency task instructions are automatically allocated and executed.

[0031] In actual application, the preset abnormal scene template covers common offshore operation risks such as personnel falling into the water, ship deviation, equipment failure, etc., and includes emergency response processes and role division requirements for each type of event. Through template calling, it can ensure that emergency operations are carried out according to the predetermined procedures immediately when an event occurs, avoid the delay and confusion of traditional manual judgment, and improve the response speed and execution accuracy. In actual emergencies, some roles may not be able to perform tasks immediately due to personnel fatigue or temporary absence. Comparing the template role requirements with the actual allocation results of the on-site roles, the system can dynamically find the gap positions and automatically dispatch available personnel to fill the key positions, ensuring the integrity and execution of emergency response, achieving dynamic replacement and safety redundancy, and ensuring that each key task link has personnel on duty. The emergency task instructions of each link in the template are automatically generated and issued to the relevant personnel execution terminal through the communication system, realizing the instant command and execution closed loop, eliminating the delay, misunderstanding or omission caused by manual instruction, ensuring that the emergency response tasks are completed according to the preset order, role division and operation specification, thereby minimizing the impact of accidents.

[0032] According to the emergency response process in the abnormal scene template, the step of automatically allocating emergency task instructions and issuing execution is as follows: Based on the emergency response process in the abnormal scene template, the emergency task is decomposed into a plurality of executable emergency task instructions, and the execution person identity information and the acceptance execution time limit for each task instruction are bound; The emergency task instruction is issued to the acceptance execution interrupt through a wireless communication device. If no confirmation execution feedback is received within the acceptance execution time limit, a task secondary allocation mechanism is triggered to transfer the emergency task instruction to a backup execution person.

[0033] In actual application, by binding the execution person identity information for each task instruction, it is ensured that each task has a clear responsible person, avoiding the situation of no execution or repeated execution. At the same time, the acceptance execution time limit is set for the task, which can ensure that the emergency task is responded within the specified time, improve the overall emergency response speed and efficiency, and make the emergency response process more controllable and traceable, taking into account the high-risk environmental characteristics of offshore operations. If no confirmation feedback is received within the acceptance execution time limit, a task secondary allocation mechanism is triggered to ensure reliable execution of the emergency task. Even if the first allocated execution person fails to respond in time due to communication interruption, physical fatigue or other reasons, the system can automatically start secondary allocation to transfer the task to a backup execution person, ensuring uninterrupted emergency response, achieving task execution redundancy and intelligent remediation, and minimizing the expansion of accidents caused by single point failure, improving the reliability and safety of offshore operation emergency handling.

[0034] The closed-loop safety module 5 calculates a closed-loop safety index of the target operation after the target operation is completed, feeds back the closed-loop safety index to a risk score account, and forms a step of a dynamically updated safety traceability mechanism, specifically: After the target operation is completed, the number of trimming instructions triggered during the completion of the target operation and the number of emergency responses are obtained, and the process risk warning data is generated in combination; The emergency task completion rate and the emergency task response degree during the completion of the target operation are obtained, and the abnormal handling effect data is generated in combination; The personnel data returning to the port are obtained, the process risk warning data, the abnormal handling effect data and the personnel data returning to the port are weighted and comprehensively calculated to obtain a closed-loop safety index; The closed-loop safety index is fed back to the risk score account of the corresponding target operation personnel and the ship, and if the closed-loop safety index is higher than a preset safety index threshold, the risk score of the corresponding target operation personnel and the ship is reduced; If the closed-loop safety index is lower than the preset safety index threshold, the risk score of the target operation personnel and the ship is increased, and a key risk target operation personnel or target operation ship marker is triggered.

[0035] In actual application, the number of trimming instructions reflects the fatigue management of the operation personnel, the number of emergency responses reflects the handling of the emergency event, and the process risk warning data generated in combination can comprehensively evaluate the potential safety risk in the operation process. The emergency task completion rate and the response degree reflect the timeliness and effectiveness of the emergency event handling, and the abnormal handling effect data generated in combination can measure the safety performance of the target operation personnel and the ship in the emergency event, so as to ensure that the closed-loop safety index can comprehensively evaluate the process and result of the operation safety management. The closed-loop safety index generates a closed-loop safety index through weighted comprehensive analysis of the risk intervention in the operation process, the abnormal handling effect and the personnel data returning to the port. The index can not only reflect the safety management level of the operation process, but also reflect the safety closed-loop state after the operation. A high safety index indicates that the operation personnel and the ship perform well in the entire operation cycle, and the risk control is in place. The risk score can be reduced as an incentive mechanism to encourage safe operation, establish positive feedback, and promote the personnel and the ship to continuously maintain safe behavior in subsequent tasks. A low safety index indicates that there are risk events or poor intervention effects during the operation, the risk score is increased, and the key risk object is marked, which can remind the manager to control the high-risk personnel or ship, limit their participation in subsequent high-risk operations, and form a dynamic safety traceability mechanism. This step realizes risk closed-loop management and ensures that the safety management system is sustainable and dynamically adjustable.

[0036] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
