Description

Technical Field

[0001] The present invention relates to the technical field of emergency management systems, and in particular to a comprehensive emergency command system. Background Art

[0002] In the current power production industry, the emergency command system is a key link in ensuring the safe and stable operation of power facilities. Its effectiveness is directly related to the timeliness and effectiveness of emergency response. However, the existing emergency command system has obvious deficiencies in its response mechanism. When power stations encounter emergencies such as equipment failures, natural disasters and other emergencies, especially large-scale failures caused by the incident, the system often finds it difficult to quickly and accurately determine the specific location of the incident and can only make preliminary regional judgments based on the scope of the incident. This judgment method is not only time-consuming, but also lacks accuracy, which seriously restricts the speed and efficiency of emergency response.

[0003] In addition, since the specific location of the incident cannot be effectively locked, the system is also difficult to achieve rapid and effective deployment of emergency resources, resulting in the rescue force being unable to arrive at the accident site in time, delaying the best time to deal with it. At the same time, the implementation of existing emergency measures is generally a framework-based emergency guidance. Although it can be used for most emergencies, when emergencies are concrete, there is a lack of specific emergency measures, which makes it difficult to accurately issue decisions when specific measures need to be taken. Targeted rescue countermeasures are also required, which lack comprehensiveness and effectiveness, affecting rescue efficiency. It also lacks the flexibility of dynamic adjustment, making it difficult for the response mechanism to fully play its due role in actual operations, further affecting the timeliness, comprehensiveness and reliability of emergency event handling.

[0004] Therefore, it is urgent to develop an emergency command system that can comprehensively control response mechanisms, event judgment, resource coordination, and implementation of emergency measures to achieve comprehensive management and dispatch. Summary of the invention

[0005] The present invention aims to provide a comprehensive emergency command system to solve the problem that the existing emergency management system is not comprehensive enough and it is difficult to quickly identify the incident point so as to take effective response measures in time, which affects the rescue efficiency and increases the manpower and material costs.

[0021] The following is further described in detail through specific implementation methods:

[0022] Embodiment 1

[0023] This embodiment is shown in the attached Figure 1As shown, a comprehensive emergency command system improves the comprehensiveness and effectiveness of the emergency mechanism by establishing necessary emergency handling mechanisms in the process of pre-prevention, incident response, in-event disposal and aftermath management of power station emergencies. At the same time, by rationally utilizing equipment means to quickly determine the point of occurrence, narrow the search scope, and reduce human resource investment, the emergency plan can be quickly determined, the rescue efficiency and effectiveness can be improved, the loss and impact range can be minimized, and the operation and personal safety can be guaranteed. In this embodiment, the emergency command system includes an emergency plan unit, an emergency command and dispatch unit, an emergency drill management unit, and an emergency material management unit.

Public health events include sudden disease transmission, major food poisoning, major environmental pollution, nuclear radiation, and the like. Social security events include sudden mass incidents, network and information security incidents, financial events, public opinion event news handling, sudden confidentiality events, and the like.

[0026] According to the types of emergencies, corresponding emergency mechanisms are established respectively. In this embodiment, the emergency mechanism includes but is not limited to the pre-prevention mechanism, the incident response process, the in-process disposal measures, and the post-event improvement management and other response plans to ensure the establishment of a comprehensive and targeted response mechanism, to achieve rapid acquisition and take corresponding effective measures, and to improve the ability to handle emergencies. According to the type of emergency, the event emergency level is established under the corresponding event type. In this embodiment, according to the urgency and impact range of the emergency, it is divided into level I (especially serious), level II (serious), level III (large) and level IV (general), among which level I is the highest level. At the same time, the corresponding response level is established for the event emergency level, among which level I to level III is for the first-level response of enterprise management and the first-level response of grassroots units, and level IV corresponds to the third-level response of enterprise management and the second-level response of grassroots units. In this way, the event process nodes are quickly clarified, the response efficiency and response measures are improved, and the event handling efficiency is improved.

[0027] In this embodiment, the degree of urgency is determined based on the suddenness of the emergency, the speed of development, and the degree of immediate harm that may be caused; the scope of impact is determined based on the geographical breadth of the emergency, the number of people affected, and the possible long-term impact.

[0028] The emergency command and dispatch unit is used to initiate the emergency process according to the emergency level of the emergency and the emergency mechanism, and implement command, dispatch and control.

[0029] In this embodiment, the emergency command and dispatch unit includes a main process configuration module, an event level management module, each level process configuration module, a command and dispatch module, a task tracking module and a task management module.

[0030] The main process configuration module is used to select currently available equipment to survey the emergency scene according to the set mode based on the acquired event information and determine the point where the emergency occurred.

[0031] In this embodiment, the setting mode is to pre-set multiple basic points in each defined supervision area, which are defined as a basic point set, represented by B = {B 1 ,B 2 ,...B n}, where n represents the total number of basic points. Basic points within the set range are selected according to the geographical location of the emergency scene, that is, in each supervision area, multiple basic points are pre-selected based on geographical features, population density, traffic conditions and other factors, so that these basic points have good accessibility and vision, so that they can be quickly reached and surveyed when an emergency occurs.

[0032] When an emergency occurs, the location of the emergency is initially determined based on the initial information obtained, such as the power outage area, the direction of the explosion, the direction of the smoke, etc., and the current available equipment is selected in combination with the actual status, such as available satellite positioning, cameras, drones, single-soldier maps, etc. The available equipment set is obtained by setting, which is represented by D = {D 1 ,D 2 ,...D m}, where m is the total number of available devices. Select several nearest basic points from the determined area E, that is, quickly search for 1-5 relatively close basic points in different directions within the initially determined area. In this embodiment, based on the distance metric, search and select the k basic points closest to the emergency scene, 1<k<5, which can be expressed as |B'|=k∑B i ∈B'A(B i ,E), where A(B i ,E) represents the i A measure of the distance or accessibility to the emergency site E.

[0033] Select the currently available devices and select the most suitable device based on the status, function and location of the device, represented by D se =f D(D,E,I), where f D (D, E, I) is the set device selection function; I represents the acquired analysis information, including recorded historical data, current environmental information, and human habits. The device selected by the control starts from the selected basic point and combines the currently acquired analysis information to search and find out the point where the emergency occurs.

[0034] The event status is analyzed and judged based on the preliminary information obtained on the scene, and the information is combined for prediction, the direction and cause of the current emergency may be inferred, the available equipment is controlled to infer the direction and cause in the information, and after determining the best investigation path, the search and investigation are carried out along the path. In this embodiment, based on the selected basic points, equipment, inferred direction and cause, the best planned path can be obtained, which can be expressed as P best =f P (B se ,D se ,θ(J(I)),C(J(I))), where J(I) is the judgment of the event based on the analysis information I; θ(J(I)) is the direction of the possible occurrence of the emergency based on the judgment of J(I); C(J(I)) is the cause of the possible occurrence of the emergency based on the judgment of J(I). This can achieve targeted search and investigation, shorten the time for confirming the incident point, reduce the investment in human resources, and improve overall efficiency.

[0035] In this embodiment, historical data related to the event is collected according to the event type, including the time, location, type, cause, impact, etc. of similar events in the past, and the historical data is cleaned, sorted and analyzed, such as by standardization processing, scaling the data to the same scale. Valuable information and rules are extracted as reference values ​​for time judgment. In this embodiment, linear regression is used for data analysis and extraction, which can be expressed as in, is the predicted dependent variable value; β 0 is the intercept term; β 1 , β 2 , ..., β n is the regression coefficient, which is the influence of each independent variable on the dependent variable, and can be flexibly set according to actual data and needs; 1 , x 2 , ..., x n is the independent variable, i.e., the feature.

[0036] At the same time, the operator information in each station and area is recorded, their behavior data is extracted, and behaviors that may cause risks are marked to form human habit information, such as smoking, operating errors, absenteeism, historical maintenance records and other behavioral characteristics, and real-time record of the current environment's temperature, humidity, air pressure, wind direction, geographic location, surrounding buildings and facilities and other environmental characteristics information. The record of human habits and environmental information can be expressed as Among them, score is the behavioral characteristic score or environmental characteristic score; w i is the weight of the i-th feature, indicating the impact of this feature on the risk; b i is the number of occurrences or severity of the i-th feature; n is the total number of features.

[0037] Finally, the possible causes of the emergency are obtained based on the comprehensive indicators, and marked as reminders for quick investigation. The final analysis method can be expressed as Among them, overall_score is a comprehensive evaluation index; a j is the weight of the jth analysis result, which can be flexibly set according to actual data and needs; metric j is the value of the jth analysis result; m is the total number of analysis results.

[0038] According to the preliminary information on the scene and the various types of information collected, the status of the event is judged, and predictive analysis is performed using technical means such as data mining and machine learning to obtain inferred information. In this embodiment, the inferred information includes the direction of the occurrence point of the event, the cause of the event, the development stage, the scope of impact, the severity, etc. Based on the inferred information, the selected basic point is used as the initial point, combined with the terrain, traffic conditions, personnel distribution and other factors at the scene of the event, the best investigation path for the available equipment is determined, and then the available equipment is controlled for rapid investigation. In the investigation process, new information and data are collected in a timely manner to update and correct the status of the event. Ensure that accurate and effective information can be quickly obtained in the initial stage of the event, and narrow the scope of the event, further improve the efficiency of event confirmation, and reduce the investment in human resources and time costs.

[0039] The event level management module is used to identify the urgency and impact of an event, and to determine the emergency level of the emergency event; the corresponding emergency plan process is adopted according to the determined emergency level.

[0040] In this embodiment, the acquired event information is analyzed to evaluate the event type and the emergency level of the current event, and the corresponding level and emergency mechanism are activated according to the determined emergency level, thereby shortening the information transmission time, improving the timeliness of event processing, and avoiding missing the best rescue time. At the same time, according to the activated emergency mechanism, some rescue personnel can quickly take effective measures according to the actual situation to improve processing efficiency and increase collaborative operation capabilities, avoid ineffective processing caused by problems such as information asynchrony and information lag, and improve resource utilization efficiency.

[0041] The command and dispatch module is used to provide decision support and coordination arrangements based on the activated emergency plan process and the current resource status.

[0042] In this embodiment, according to the latest information of the current event analysis, the status information of available resources is obtained, including various types of materials, equipment, venues, and personnel teams, and the geographical location and affiliated units of each resource material are obtained. According to the emergency level and status of the event, the corresponding resource scheduling decision and coordination method are generated and sent to the management center. The management center realizes rapid resource allocation through the equipped communication system, including voice, video and other communication methods, to ensure that the materials can be quickly in place and maximized, while reducing unnecessary waste. Through accurate demand forecasting and scientific resource allocation strategies, the efficiency and benefits of resource scheduling are comprehensively improved.

[0043] The task tracking module is used to track and record the task progress after the emergency process is started, to ensure that each link is controllable and traceable, to ensure the timeliness of task completion, to ensure that the emergency plan and each process link can be effectively implemented, and to ensure the smooth completion of emergency work. The task management module is used to coordinate and manage the published task information after the emergency process is started, and to manage and maintain the task data to form effective event data, which is used to constitute event history data.

[0044] The emergency drill management unit is used to formulate emergency drill plans, implement emergency drills according to the plans, and summarize the drill results to the emergency plan unit for updating the emergency mechanism.

[0045] In this embodiment, the emergency drill management unit includes a drill planning module, a process management module, an evaluation and summary module, and a drill statistics module.

[0046] The drill plan module is used to develop drill plans for emergencies and update them regularly. The process management module is used to record the implemented drill process and maintain process information, so as to facilitate the query, viewing and management of relevant information. The evaluation and summary module is used to evaluate the drill process, summarize and record it, and provide optimization suggestions for the drill plan. The drill statistics module is used to count the drill data of each type of emergency. The emergency drill management unit can be used to update and optimize the emergency mechanism, further ensure the completeness and fit of the emergency mechanism, make the emergency mechanism more applicable, effectively improve the emergency handling capacity and rescue efficiency, and reduce the loss of human resources.

[0047] The emergency material management unit is used to set corresponding material points and allocate emergency material resources according to the emergency response mechanism.

[0048] The emergency resource management unit includes a material module, a personnel module, a transportation module, and a facility and equipment module. The material module is used to record and manage the material information in the corresponding station area. In this embodiment, the material information includes the current status, affiliated unit, geographical location, maintenance records, etc. The personnel module is used to manage the emergency rescue team information and real-time mobilization status. The transportation module is used to manage and record transportation resource information, which includes transportation equipment, transportation support agencies, etc. The facility and equipment module is used to manage and record the resource information of emergency facilities, equipment and places (such as shelters, etc.).

[0049] In this embodiment, the emergencies are classified according to their nature to ensure the establishment of a comprehensive and effective emergency mechanism for emergencies, and to formulate targeted emergency plans and measures to ensure the comprehensive, efficient and accurate emergency management and command of emergencies in power stations. At the same time, the key links such as preventive preparation, immediate response, event handling and subsequent recovery are closely linked to ensure that the emergency mechanism is both comprehensive and targeted. Through the pre-established basic points and historical data, the root cause of the accident can be quickly identified while reducing the consumption of manpower and physical resources, and the corresponding emergency plan can be immediately triggered to achieve rapid and accurate handling of the incident, thereby ensuring the timeliness and accuracy of the response.

[0050] In terms of resource allocation, various tasks are deployed and coordinated quickly to minimize the loss of manpower and material resources, thereby improving the efficiency of emergency response and ensuring the efficient allocation of rescue resources. In addition, through regular emergency drills, the emergency mechanism can be continuously optimized and improved, its flexibility and adaptability can be enhanced, and strategies can be quickly adjusted and the most effective response measures can be taken in the face of various emergencies.

[0051] Embodiment 2

[0052] In this embodiment, when selecting the corresponding emergency mechanism, the optimal emergency plan is selected according to the currently analyzed event status and impact level, wherein the event status includes the current status and the status in the future, and the impact level includes the current impact level and the future impact level.

[0053] According to the event type, the impact of the emergency event in the current and future period, as well as the possible harm and loss degree, are comprehensively analyzed to generate the current loss coefficient C current and future loss coefficient C future , in order to evaluate the comprehensive loss of the corresponding emergency mechanism, and take the emergency mechanism with the smallest comprehensive loss as the emergency plan. In this way, we can consider the handling of emergencies from the perspective of long-term development, balance the losses and harms caused by emergencies, minimize the impact of emergencies, and improve the comprehensive handling ability of emergencies.

[0054] In this embodiment, the future time period can be set according to the actual emergency event. For example, in the case of a fire, due to its rapid development and high degree of urgency, the prediction can be set in hours. For example, for an impact such as nuclear radiation, which has a long cycle and is difficult to completely deal with in a short period of time, the prediction and evaluation can be set in years. In the case of effective current handling, the long-term impact can be further considered to reduce the impact on future development.

[0055] Therefore, in this embodiment, the future time period can be set as T, and T can be set to hours, days, months or years according to the event type. For each emergency mechanism u, its comprehensive evaluation value M is calculated. u , which can be expressed as

[0056]

[0057] In the formula, It indicates the relative degree of current loss when the u-th emergency mechanism is adopted; It represents the relative degree of future losses when the u-th emergency mechanism is adopted; To convert future losses into a scale comparable to current losses; α is the weight of current losses, which can be flexibly adjusted according to actual events and other factors; (1-α) is the weight of future losses. Compare the comprehensive evaluation values ​​M of each emergency mechanism u , select M u The smallest emergency mechanism is the optimal solution. u The smaller it is, the better the emergency mechanism performs in balancing current and future losses.

[0058] In this embodiment, the selected emergency mechanism needs to be comprehensively judged and is not selected entirely based on the optimal processing result that can be achieved at present. Instead, it needs to be combined with the nature of the event, consider the long-term impact, and select the plan with the lowest overall hazard impact after comprehensive evaluation, so as to balance the losses and hazards caused by the emergency and minimize the impact of the emergency.

[0059] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
