[0040] Overall concept of the present invention

[0041] Firstly, according to the actual needs and characteristics of power emergency rescue medical collaboration, its key elements and processes are deeply analyzed, and a conceptual model of power emergency rescue medical collaboration is constructed. The model should clarify the goals, principles and requirements of collaboration, laying the foundation for the subsequent construction of reference architecture models and standard system frameworks.

[0042] Next, based on the conceptual model, a reference architecture model for power emergency rescue medical collaboration is further constructed. The model should describe the organizational structure, workflow, and technical support in detail, clarify the responsibilities and collaboration methods of each participant, and ensure the smooth progress of the entire collaboration process;

[0043] Then, combining the conceptual model and the reference architecture model, a standard system framework for medical collaboration in power emergency rescue is established. The framework should cover four aspects: information collaboration standards, equipment collaboration standards, decision-making collaboration standards, and execution collaboration standards. Detailed standards and specifications should be formulated to ensure the standardization and efficiency of the entire collaboration process.

[0044] At the same time, the power emergency rescue medical collaborative standard system is used to collect and analyze relevant data in real time through the data collection module, the model construction module is used to automatically build and optimize the collaborative model, and the standard system generation module is used to automatically generate a standard system framework that meets actual needs, thereby realizing the automation and intelligent construction of the power emergency rescue medical collaborative standard system.

[0045] Embodiment 1

[0046] like Figure 1 As shown, this embodiment provides a method for constructing a power rescue medical collaborative standard system, including the following steps:

[0047] S101: Acquire various historical data related to power emergency rescue medicine;

[0048] S102: Analyze the inherent laws and correlations of various historical data related to power emergency rescue medicine, and identify the key factors and links that affect the coordination of power emergency rescue medicine;

[0049] S103: Develop corresponding information coordination standards, equipment coordination standards, decision-making coordination standards, and execution coordination standards for key factors and links that affect medical coordination in power emergency rescue;

[0050] S104: Analyze actual power emergency rescue medical data based on the constructed power emergency rescue medical collaboration standard system to obtain information collaboration, equipment collaboration, decision-making collaboration and execution collaboration solutions that meet the needs of the scenario.

[0051] The purpose of the medical coordination standard system for power emergency rescue is to achieve information coordination, equipment coordination, decision coordination and execution coordination in the power emergency rescue process by formulating unified standards and specifications, and to ensure smooth information flow, resource sharing and consistent decision-making among all participants. The establishment and implementation of this standard system will significantly improve the quality and efficiency of power emergency rescue work and provide strong guarantees for the safe and stable operation of the power industry.

[0052] In S101, various historical data related to power emergency rescue medicine include:

[0053] Rescue case data: Data on rescue cases of power accidents over the years, analyzing coordination issues in the rescue process and providing empirical support for model building;

[0054] Medical resource data: including the distribution of medical institutions, medical personnel, medical equipment and other resources, in order to assess the coordination capabilities in emergency rescue;

[0055] Technical support data: Collect the current status and trends of technological development related to power emergency rescue medical collaboration to evaluate the impact of technology on collaboration.

[0056] Acquire various historical data related to power emergency rescue medicine, and pre-process various historical data related to power emergency rescue medicine in order to extract valuable information.

[0057] Preprocessing various historical data related to power emergency rescue medicine is performed, and the data preprocessing steps include but are not limited to:

[0058] Data cleaning: Remove duplicate, erroneous or incomplete data to ensure data accuracy and consistency.

[0059] Among them, in S102, the inherent laws and correlations of various historical data related to power emergency rescue medicine are analyzed to identify the key factors and links that affect the coordination of power emergency rescue medicine, including:

[0060] Data analysis: Use statistical analysis, data mining and other methods to extract the inherent laws and correlations of data to provide support for model construction;

[0061] Data visualization: Display data analysis results through charts, images, etc. to make data easier to understand and apply.

[0062] Among them, the key factors and links include time factors, space factors and resource factors;

[0063] Time factors include the response time from receiving a rescue request to initiating emergency rescue, the time interval from the patient being injured to receiving professional medical treatment, and the coordination time between different rescue units;

[0064] The spatial factor is to analyze the geographical distribution of power accidents and compare the matching degree between the geographical distribution of rescue resources and the accident location;

[0065] Resource factors include evaluating the number, skills and distribution of rescue personnel, and analyzing the type, quantity and performance of rescue equipment.

[0066] By constructing a conceptual model of medical collaboration for power emergency rescue, the model not only defines the basic concepts, goals, principles and key elements of medical collaboration for power emergency rescue, but also deeply analyzes the interaction between the elements, providing a solid theoretical support for the subsequent construction of the standard system.

[0067] In S103, formulate coordination standards: formulate corresponding coordination standards for key elements, including information coordination standards, equipment coordination standards, decision coordination standards, and execution coordination standards;

[0068] First, clarify the core position of the time factor in the coordination standard, set reasonable standards for response time, treatment time and coordination time, and ensure the efficiency and timeliness of rescue operations;

[0069] Secondly, we should take into full account the impact of spatial factors on coordination standards, analyze the geographical distribution characteristics of power accidents, and formulate coordination strategies for different regions based on the distribution of rescue resources;

[0070] Then, in terms of resource allocation, a resource information sharing platform should be established to achieve information exchange and resource sharing among rescue units, formulate priorities and sequences for resource allocation, and ensure that the required resources can be quickly mobilized at critical moments.

[0071] like Figure 2 As shown in the figure, information coordination standards are the core part of medical coordination in power emergency rescue, covering standards for information collection, transmission, processing, analysis and application; these standards include information format, transmission protocol, data processing method, information sharing mechanism, aiming to achieve information exchange and sharing among all participants and improve the efficiency and accuracy of emergency rescue;

[0072] like Figure 3 As shown in the figure, the equipment coordination standard focuses on the standards of equipment and facilities required for medical coordination in power emergency rescue, including the selection, configuration, use and maintenance standards of rescue equipment, as well as the layout, function and use standards of medical facilities; these standards are formulated to ensure the coordination and compatibility of rescue equipment and facilities, and to improve the efficiency and safety of rescue work;

[0073] like Figure 4 As shown in the figure, the decision-making coordination standard involves the decision-making and coordination process in the medical coordination of power emergency rescue, which includes the standards of decision-making process, decision-making method and decision support system. These standards are aimed at ensuring the scientificity, rationality and efficiency of decision-making and improving the pertinence and effectiveness of emergency rescue work.

[0074] The execution coordination standards focus on the execution process and coordination mechanism in the medical coordination of power emergency rescue, which includes standards for the organization, command, coordination and supervision of rescue operations; these standards are formulated to ensure the orderliness, efficiency and safety of rescue operations and improve the overall effectiveness of emergency rescue work.

[0075] Improve the standard system: Integrate various collaborative standards into a complete standard system to ensure the coordination and complementarity among various standards.

[0076] Through the above scheme, a set of standard systems specifically for power emergency rescue medical coordination can be formed to provide strong support for power companies' emergency rescue. This standard system can not only guide the information coordination, equipment coordination, decision coordination and execution coordination among all participants, but also promote the standardization, digitization and intelligent development of power emergency rescue medical coordination, and improve the emergency rescue level and capabilities of the entire power industry.

[0077] In S104, based on the constructed power emergency rescue medical collaboration standard system, the actual power emergency rescue medical data is analyzed to obtain information collaboration, equipment collaboration, decision-making collaboration and execution collaboration solutions that meet the scenario;

[0078] Under the standard system of power emergency rescue medical collaboration, subsequent applications are carried out, including but not limited to:

[0079] Guiding practice: providing specific operation guidelines and specifications for medical collaboration in power emergency rescue, and guiding rescue personnel in collaborative work in practice;

[0080] Optimize resource allocation: Through the application of the standard system, medical resources and technical support can be more reasonably allocated to improve rescue efficiency and quality;

[0081] Promote technological innovation: The standard system can serve as the direction and basis for technological innovation and promote the continuous development of power emergency rescue medical collaborative technology;

[0082] In actual use, for example, when the actual scenario is an emergency situation caused by a power system failure, the power emergency rescue medical data in the scenario is obtained, including:

[0083] Rescue response data: records the time from receiving the fault notification to the departure of the rescue team, and the time required to arrive at the accident scene;

[0084] Medical treatment data: collect the time data from the time the injured person is injured to the time they receive initial medical treatment, as well as subsequent detailed records of the treatment process;

[0085] Resource dispatch data: including personnel allocation of rescue teams, use of medical equipment, material consumption and supply, etc.;

[0086] Collaborative operation data: records the collaboration between different rescue units, including information exchange, task allocation, and execution coordination.

[0087] The above data are analyzed through the constructed power emergency rescue medical collaborative standard system. The specific analysis process is as follows:

[0088] Data standardization: According to information collaboration standards, the collected data is converted into a unified format for easy analysis and comparison;

[0089] Time efficiency analysis: Based on the coordinated standards of response time and treatment time, the time efficiency of rescue operations is evaluated and possible delay points are identified;

[0090] Resource allocation assessment: Based on equipment coordination standards and resource factor analysis, assess whether the allocation of rescue resources is reasonable and whether it meets on-site rescue needs;

[0091] Collaboration efficiency evaluation: Use decision-making coordination standards and execution coordination standards to evaluate the coordination efficiency between different rescue units and analyze the effectiveness of coordinated operations;

[0092] Problem identification and improvement suggestions: Through the above analysis, identify the problems existing in collaborative operations and put forward suggestions for improving rescue response, resource allocation and coordination mechanism;

[0093] Plan formulation: Based on the analysis results, formulate a specific collaborative rescue plan, including information flow plan, resource allocation plan, decision support plan and execution supervision plan;

[0094] Simulation exercise: Apply the collaborative solution in a simulated environment, evaluate its effectiveness, and further adjust and optimize it;

[0095] Practical application: Apply proven collaborative solutions to actual rescue operations to ensure that rescue work is carried out in an orderly and efficient manner;

[0096] Feedback and iteration: Collect feedback information from rescue operations and iteratively optimize the standard system to adapt to the ever-changing rescue environment and needs.

[0097] Through the above supplements, the solution in the document is more complete and can clearly guide how to apply the constructed standard system to actual power emergency rescue medical coordination, and how to continuously optimize and improve this system through practice.

[0098] Finally, we get the information coordination, equipment coordination, decision coordination and execution coordination solutions that meet the needs of this scenario.
