Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of emergency material dispatching, and in particular to an emergency material dispatching method based on Beidou grid location code and accident simulation. Background Art

[0002] In view of the characteristics of emergencies, after analyzing the dispatch of emergency materials after an accident, it is found that the current research paradigm of emergency material dispatch is mostly "prediction-response". This paradigm gradually exposes the shortcomings of large deviations in material quantity budgets. When facing emergencies, due to insufficient estimation of the disaster situation and inadequate consideration of the actual situation and uncertainty, sufficient emergency materials cannot be transported to the disaster site, affecting the efficiency of rescue. Summary of the invention

[0003] In view of this, the embodiment of the present application proposes an emergency material dispatch method based on Beidou grid location code and accident simulation, which conducts rapid accident simulation after the emergency occurs, and adopts a "scenario-response" model to dispatch emergency materials according to the simulation results, so as to ensure the timely and effective supply of emergency materials, reduce the uncertainty in the dispatch process, and effectively protect the lives of the affected people and the property safety of the industrial park.

[0004] In the first aspect, an embodiment of the present application proposes an emergency material dispatch method based on Beidou grid location code and accident simulation, comprising the following steps: gridding the map of the industrial park based on the Beidou grid location code standard to obtain a grid map of the industrial park, assigning a unique Beidou grid location code to each grid unit in the grid map, and establishing a static attribute table and a dynamic attribute table for the grid unit; wherein the static data table is used to store hazardous chemical information, monitoring sensing equipment information and building information, and the dynamic data table is used to store number information and data collected by monitoring sensing equipment; different emergency plans are obtained and stored in a plan library; wherein the emergency plan is set based on possible accidents in the industrial park, and the emergency plan corresponds to an emergency team and emergency materials; when alarm information is obtained, determine the corresponding The location where the accident occurred is determined by combining the alarm information with the static attribute table and the dynamic attribute table of the grid unit where the accident occurred. Then, according to the location where the accident occurred, the accident type and the accident level, the corresponding target emergency plan is matched in the plan library and started, and the emergency team corresponding to the target emergency plan is assigned to carry the emergency materials corresponding to the target emergency plan to the location where the accident occurred; based on the static data table and the dynamic data table of the grid unit where the accident occurred and its adjacent grid units, an accident simulation is performed to simulate the corresponding accident spread range, the probability of a secondary accident and the number of injured within the first preset time, and combined with the emergency materials corresponding to the target emergency plan, the additional emergency materials are determined; and idle emergency teams are assigned to carry the additional emergency materials to the vicinity of the accident location.

[0005] Through the above method, the map of the industrial park is gridded based on the Beidou grid location code standard to obtain the grid map of the industrial park, and each grid unit in the grid map is assigned a unique Beidou grid location code, and static data tables and dynamic data tables are established to make the industrial park Beidou grid-based, and information such as hazardous chemicals, monitoring and sensing equipment, buildings and number of people are included in scientific grid management. Set up a plan library to store different emergency plans based on possible accidents in the industrial park. When an emergency occurs, immediately determine the location, type and level of the accident, match the corresponding target emergency plan from the plan library, and assign the emergency team corresponding to the target emergency plan to carry the emergency materials corresponding to the target emergency plan to rush to the accident location for rescue in the shortest time. At the same time, the operation and maintenance center conducted accident simulation based on the static data tables and dynamic data tables of the grid unit where the accident occurred and its adjacent grid units, predicted the entire process of the accident spread, determined the emergency material interface based on the accident simulation results, and assigned idle emergency teams to rush to the vicinity of the accident location with additional emergency materials. A "scenario-response" scheduling model was used to dispatch emergency materials, ensuring the timely and effective supply of emergency materials, reducing uncertainty in the scheduling process, and effectively protecting the lives of the affected people and the property safety of the industrial park.

[0006] Optionally, if the accident type is fire, the static data table and dynamic data table of the grid unit where the accident occurred and its neighboring grid units are used to perform accident simulation, and simulate the corresponding accident spread range, secondary accident probability and number of injured persons within the first preset time, including: determining the accident spread direction based on the wind direction information in the dynamic data table of the grid unit where the accident occurred, and the building information and flammable material information in the static data table of the grid unit where the accident occurred and its neighboring grid units; determining the accident spread speed based on the wind speed information and humidity information in the dynamic data table of the grid unit where the accident occurred, and simulating the corresponding accident spread range within the first preset time based on the accident spread direction and the accident spread speed; simulating the corresponding probability of a secondary fire accident and the type of a secondary fire accident within the first preset time based on the hazardous chemical information in the static data table of the grid unit where the accident occurred, and the hazardous chemical information in the static data tables of each grid unit within the accident spread range; simulating the corresponding number of injured persons within the first preset time based on the number of people information in the dynamic data tables of each grid unit within the accident spread range, the fire accident injury ratio, and the accident injury ratio corresponding to the type of secondary fire accident.

[0007] Optionally, the emergency supplies corresponding to the target emergency plan are combined to determine the supplementary emergency supplies, including: determining the types and total amount of emergency supplies required to completely solve the fire accident based on the scope of the accident spread, the probability of the secondary fire accident, the type of the secondary fire accident and the number of injured; determining the types and total amount of emergency supplies gaps based on the types and total amount of emergency supplies required to completely solve the fire accident, and the types and total amount of emergency supplies corresponding to the target emergency plan; multiplying the types and total amount of the emergency supplies gap by a preset surplus ratio to determine the types and total amount of supplementary emergency supplies. Fire accidents may cause secondary accidents such as explosions, building collapses, and harmful gas leaks. The emergency rescue supplies for fire accidents set in the target emergency plan may not be able to cope with these secondary accidents. Therefore, it is necessary to calculate the types and total amount of missing emergency supplies based on the accident simulation results, and then multiply them by the preset surplus ratio to increase the fault tolerance space, and finally determine the supplementary emergency supplies and assign idle emergency teams to the accident location and participate in the rescue, which effectively improves the rescue speed and intensity.

[0008] Optionally, if the accident type is a leak of harmful gas, the static data table and the dynamic data table of the grid unit where the accident occurred and its neighboring grid units are used to perform an accident simulation to simulate the corresponding accident spread range, secondary accident probability and number of injured persons within the first preset time, including: determining the accident spread direction based on the wind direction information in the dynamic data table of the grid unit where the accident occurred and the building information in the static data table of the grid unit where the accident occurred; determining the accident spread speed based on the wind speed information, temperature information and humidity information in the dynamic data table of the grid unit where the accident occurred, and simulating the corresponding accident spread range within the first preset time based on the accident spread direction and the accident spread speed; simulating the corresponding probability of a secondary accident of harmful gas leakage and the type of secondary accident of harmful gas leakage within the first preset time based on the hazardous chemical information in the static data table of the grid unit where the accident occurred and the hazardous chemical information in the static data tables of each grid unit within the accident spread range; simulating the corresponding number of injured persons within the first preset time based on the number of people information in the dynamic data tables of each grid unit within the accident spread range, the injury ratio of harmful gas leakage accidents and the accident injury ratio corresponding to the type of secondary accident of harmful gas leakage.

[0009] Optionally, the emergency supplies corresponding to the target emergency plan are combined to determine the supplementary emergency supplies, including: based on the scope of the accident, the probability of the occurrence of the secondary accident of harmful gas leakage, the type of the secondary accident of harmful gas leakage and the number of injured, determine the type and total amount of emergency supplies required to completely solve the harmful gas leakage accident; based on the type and total amount of emergency supplies required to completely solve the harmful gas leakage accident, and the type and total amount of emergency supplies corresponding to the target emergency plan, determine the type and total amount of emergency supplies gap; multiply the type and total amount of the emergency supplies gap by the preset surplus ratio to determine the type and total amount of supplementary emergency supplies. Harmful gas leakage accidents may cause secondary accidents such as explosions, fires, and water pollution accidents. The emergency rescue supplies for harmful gas leakage accidents set in the target emergency plan may not be able to cope with these secondary accidents. Therefore, it is necessary to calculate the type and total amount of the missing emergency supplies based on the accident simulation results, and then multiply by the preset surplus ratio to increase the fault tolerance space, and finally determine the supplementary emergency supplies and assign idle emergency teams to the accident location and participate in the rescue, which effectively improves the rescue speed and intensity.

[0010] Optionally, if the accident level of the accident is greater than the preset controllable level, then while the emergency team corresponding to the target emergency plan is assigned to carry the emergency supplies corresponding to the target emergency plan to the accident location, a saturation rescue emergency team is assigned to carry saturation rescue emergency supplies to the accident location. When the accident level of the accident is greater than the preset controllable level, the uncertainty in the rescue process is greatly increased, and the emergency supplies set in the target emergency plan are likely to be insufficient, and it takes a certain amount of time to replenish and dispatch emergency supplies based on accident simulation. Therefore, once it is detected that the accident level of the accident is greater than the preset controllable level, the saturation rescue is immediately initiated, and the saturation rescue emergency team is assigned to carry saturation rescue emergency supplies to the accident location to participate in the rescue, so as to save the lives of the affected people and the property safety of the industrial park to the greatest extent.

[0011] Optionally, after assigning an idle emergency team to carry the supplementary emergency supplies to the vicinity of the accident location, the method further includes: conducting an accident simulation again based on the static data table and dynamic data table of each grid unit within the accident spread range, the emergency supplies corresponding to the target emergency plan, and the supplementary emergency supplies, simulating the corresponding accident spread range within the second preset time, the probability of a secondary accident and the number of injured, and determining the secondary supplementary emergency supplies in combination with the emergency supplies corresponding to the target emergency plan and the supplementary emergency supplies; assigning an idle emergency team to carry the secondary supplementary emergency supplies to the vicinity of the accident location. The replenishment and dispatching of emergency supplies is carried out continuously at regular intervals. Such a design further improves the rationality of the dispatching of emergency supplies and better protects the life safety of the affected people and the property safety of the industrial park.

[0012] In the second aspect, an embodiment of the present application proposes an emergency material dispatching system based on Beidou grid location code and accident deduction, the system comprising: a Beidou grid location code management module, a plan management module, an emergency accident handling module, an accident deduction module, a supplementary calculation module and a supplementary scheduling module; the Beidou grid location code management module is used to grid the map of the industrial park based on the Beidou grid location code standard to obtain a grid map of the industrial park, assign a unique Beidou grid location code to each grid unit in the grid map, and establish a static attribute table and a dynamic attribute table for the grid unit, wherein the static data table is used to store hazardous chemical information, monitoring and sensing equipment information and building information, and the dynamic data table is used to store number information and data collected by monitoring and sensing equipment; the plan management module is used to obtain different emergency plans and store them in a plan library, wherein the emergency plan is set based on possible accidents in the industrial park, and the emergency plan corresponds to an emergency team and emergency materials; the emergency accident handling module is used to obtain an alarm signal. When an accident occurs, the accident location corresponding to the alarm information is determined, and the accident type and accident level of the accident are determined by combining the alarm information and the static attribute table and dynamic attribute table of the grid unit where the accident location is located. Then, according to the accident location, the accident type and the accident level, the corresponding target emergency plan is matched in the plan library and started, and the emergency team corresponding to the target emergency plan is assigned to carry the emergency materials corresponding to the target emergency plan to rush to the accident location; the accident simulation module is used to perform accident simulation based on the static data table and dynamic data table of the grid unit where the accident location is located and its neighboring grid units, and simulate the corresponding accident spread range, probability of secondary accident and number of injured people within the first preset time; the supplementary calculation module is used to determine the supplementary emergency materials based on the accident spread range, the probability of secondary accident, the number of injured people and the emergency materials corresponding to the target emergency plan; the supplementary scheduling module is used to assign idle emergency teams to carry the supplementary emergency materials to rush to the vicinity of the accident location.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. In the various embodiments of the present application, many technical details are proposed in order to make the reader better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is only for the convenience of description, and the specific implementation mode of the present application should not constitute any limitation. The various embodiments can be combined with each other and referenced to each other under the premise of no contradiction.

[0024] In order to solve the technical problem that the emergency material dispatch method based on the "prediction-response" type cannot transport enough emergency materials to the disaster site, an embodiment of the present application proposes an emergency material dispatch method based on Beidou grid location code and accident simulation, which is applied to the server. In this embodiment and the following embodiments, the server is named as the operation and maintenance center for explanation. The implementation details of the emergency material dispatch method based on Beidou grid location code and accident simulation proposed in this embodiment are specifically described below. The following content is only the implementation details provided for the convenience of understanding, and is not necessary for the implementation of this solution.

[0025] The specific process of the emergency material dispatching method based on Beidou grid location code and accident simulation proposed in this embodiment can be as follows: Figure 1 As shown, including:

[0026] Step 101, gridding the map of the industrial park based on the Beidou grid location code standard to obtain a grid map of the industrial park, assigning a unique Beidou grid location code to each grid unit in the grid map, and establishing a static attribute table and a dynamic attribute table for the grid unit.

[0027] In the specific implementation, the operation and maintenance center needs to pre-grid the map of the industrial park based on the Beidou grid location code standard to obtain the grid map of the industrial park, assign a unique Beidou grid location code to each grid unit in the grid map of the industrial park, and establish a static attribute table and a dynamic attribute table for each grid unit. Among them, the static data table is used to store hazardous chemical information, monitoring and sensing equipment information, and building information, and the dynamic data table is used to store the number of people information and data collected by monitoring and sensing equipment.

[0028] In one example, a grid map of an industrial park could be Figure 2 shown.

[0029] In an example, a static attribute table of a grid unit includes several static attributes, and a dynamic attribute table of a grid unit includes several dynamic attributes. The static attribute table records the stationary entity objects in the grid unit and their information that does not change with time, and the dynamic attribute table records the moving entity objects in the grid unit and their information and the information of the stationary entity objects that changes with time.

[0030] In one example, the hazardous chemical information in the static attribute table is recorded in the form of a hazardous chemical data table in the static attribute table, and the hazardous chemical data table includes: a physical and chemical property table, which is used to describe the Chinese and English names of hazardous chemicals, as well as the physical and chemical properties including melting point and boiling point; a hazard information table, which is used to describe the hazards of hazardous chemicals including toxicity and explosiveness; a monitoring plan table, which is used to describe the on-site monitoring methods of hazardous chemicals; a protective measures plan table, which is used to describe the protective measures and conventional contact treatment methods for hazardous chemicals; an emergency rescue plan table, which is used to describe the emergency treatment methods after the leakage of hazardous chemicals; a recovery and treatment plan table, which is used to describe the pollution recovery and treatment measures for water bodies and soil after the leakage of hazardous chemicals; an isolation and evacuation distance table, which is used to describe the isolation distance and evacuation distance of hazardous chemicals; and a starting instrument and equipment table, which is used to describe the instruments that need to be started after the leakage of hazardous chemicals.

[0031] In one example, the monitoring and sensing equipment includes monitoring equipment and sensing equipment. The monitoring equipment takes images and videos, and the sensing equipment obtains sensing data according to its own type, such as a temperature sensor obtains temperature data, a humidity sensor obtains humidity data, etc. Monitoring equipment includes IPC (IP Camera, network camera) and DVR (Digital Video Recorder, hard disk recorder), etc. Sensing equipment may include temperature sensors, humidity sensors, pressure gauges, speed sensors, photosensors, gas detectors, voltmeters, ammeters, and haze testers, etc.

[0032] In one example, the operation and maintenance center can obtain the collected images and videos uploaded by each monitoring device and the collected perception data uploaded by each perception device in real time through the protocols agreed upon with each monitoring device and each perception device. The agreed protocols include RJ485 protocol, RJ45 protocol, HJ212 protocol and PLC protocol.

[0033] Step 102, obtain different emergency plans and store them in a plan library. The emergency plan is set based on possible accidents in the industrial park. The emergency plan corresponds to an emergency team and emergency supplies.

[0034] In the specific implementation, the technical personnel need to set up several different emergency plans based on possible accidents in the industrial park in advance, and the operation and maintenance center obtains different emergency plans and stores them in the plan library. Among them, each emergency plan corresponds to an emergency team and emergency supplies, in addition to corresponding rescue routes, evacuation routes, shelters, etc.

[0035] In one example, the operation and maintenance center abstractly analyzes the basic elements of the emergency plan to form an indivisible element model, and draws the emergency plan on a grid map based on the element model, and organizes and visualizes the emergency resources required to execute the emergency plan.

[0036] In one example, the basic elements in the emergency plan include five elements: point elements, line elements, surface elements, volume elements and text elements. Point elements are used to express a point in the space of the industrial park, with positioning characteristics, including at least the location of the accident, the distribution point of the emergency team, the distribution point of emergency resources, the distribution point of monitoring equipment and the distribution point of sensing equipment. Line elements are used to express the current phenomenon or strip phenomenon extending in a certain direction in the space of the industrial park, including at least the boundary line, rescue route, evacuation route, road, river and contour line. Surface elements are used to express the phenomenon with continuous two-dimensional distribution in the space of the industrial park, including at least the accident impact range, simulation range, dormitory area, work area, green area and water surface. Volume elements are used to express the phenomenon with multiple surface elements distributed in the space of the industrial park, including at least personnel, trees, buildings, ships, vehicles and bridges. Text elements are used to provide auxiliary explanations of the emergency plan in text form, including at least the name, introduction and description of the emergency plan. The breakdown of the five basic elements provides a reasonable analysis of all aspects of the emergency plan, greatly improving the efficiency and success rate of the subsequent plan matching process.

[0037] Step 103, when the alarm information is obtained, the accident location corresponding to the alarm information is determined, and the accident type and accident level of the accident are determined by combining the static attribute table and dynamic attribute table of the grid unit where the alarm information and the accident location are located. Then, according to the accident location, accident type and accident level, the corresponding target emergency plan is matched in the plan library and started, and the emergency team corresponding to the target emergency plan is assigned to rush to the accident location with the emergency materials corresponding to the target emergency plan.

[0038] In the specific implementation, the operation and maintenance center obtains the alarm information in the industrial park in real time. The alarm information in the industrial park includes the alarm information manually issued by the on-duty personnel and patrol personnel, and also includes the alarm information automatically issued by the monitoring equipment and sensing equipment based on the collected data. After obtaining the alarm information, the operation and maintenance center determines the location of the accident corresponding to the alarm information, combines the static attribute table and dynamic attribute table of the grid unit where the alarm information and the accident location are located, and the authenticity of the accident. In the event of an actual accident, the accident type and accident level of the accident are determined. Then, according to the accident location, accident type and accident level, the corresponding target emergency plan is matched in the plan library and started, and the emergency team corresponding to the target emergency plan is assigned to rush to the accident location with the emergency materials corresponding to the target emergency plan.

[0039] In one example, accident types include fire, flood, earthquake, typhoon, harmful gas leakage, etc. The accident level is used to characterize the severity of the accident. Taking earthquake as an example, the accident level is the magnitude of the earthquake.

[0040] Step 104, perform accident simulation based on the static data table and dynamic data table of the grid unit where the accident occurs and its neighboring grid units, simulate the corresponding accident spread range, the probability of a secondary accident and the number of injured people within the first preset time, and determine the replenishment of emergency supplies in combination with the emergency supplies corresponding to the target emergency plan.

[0041] In a specific implementation, after the operation and maintenance center assigns the emergency team corresponding to the target emergency plan to rush to the accident location with the emergency supplies corresponding to the target emergency plan, it immediately starts to simulate the accident based on the static data table and dynamic data table of the grid unit where the accident location is located and its adjacent grid units, simulating the corresponding accident spread range, the probability of secondary accidents and the number of injured within the first preset time, and combining the emergency supplies corresponding to the target emergency plan, determines the replenishment of emergency supplies. Among them, the first preset time can be set by technicians in this field according to actual needs, and is generally set to 30 minutes.

[0042] In one example, if the accident type is fire, the operation and maintenance center first determines the direction of the accident spread based on the wind direction information in the dynamic data table of the grid unit where the accident occurred, and the building information and flammable material information in the static data table of the grid unit where the accident occurred and its adjacent grid units. Wind can promote the spread of fire and even cause flying fire, causing new fire sources, while building information and flammable material information are closely related to combustible combustion. The three affect the direction of the spread of the fire accident. When conducting accident simulation, the wind direction, building information and flammable material information are comprehensively considered, and the direction of the spread of the fire accident can be well deduced. Then. The operation and maintenance center determines the speed of the accident spread based on the wind speed information and humidity information in the dynamic data table of the grid unit where the accident occurred. The wind speed is positively correlated with the speed of the fire accident spread, and the humidity is negatively correlated with the speed of the fire accident spread. Therefore, when conducting accident simulation, the wind speed and humidity information are comprehensively considered, and the speed of the fire accident spread can be well deduced. Based on the direction of the accident spread and the speed of the accident spread, the operation and maintenance center simulates the corresponding accident spread range within the first preset time. After that, the operation and maintenance center simulates the probability and type of secondary fire accidents within the first preset time based on the hazardous chemical information in the static data table of the grid unit where the accident occurred and the hazardous chemical information in the static data table of each grid unit within the scope of the accident spread. Fire accidents may cause secondary accidents such as explosion accidents, building collapse accidents, and harmful gas leakage accidents. Finally, the operation and maintenance center simulates the number of injuries within the first preset time based on the number of people in the dynamic data table of each grid unit within the scope of the accident spread, the fire accident injury ratio, and the accident injury ratio corresponding to the type of secondary fire accidents. The fire accident injury ratio is composed of the burn ratio, fall ratio, and hypoxia ratio.

[0043] In one example, if the accident type is fire, the operation and maintenance center needs to determine the types and total amount of emergency materials required to completely resolve the fire accident based on the scope of the accident spread, the probability of a secondary fire accident, the type of secondary fire accident, and the number of injured people. Then, based on the types and total amount of emergency materials required to completely resolve the fire accident and the types and total amount of emergency materials corresponding to the target emergency plan, determine the types and total amount of emergency material gaps, and multiply the types and total amount of emergency material gaps by the preset surplus ratio to determine the types and total amount of supplementary emergency materials. The preset surplus ratio can be set by technicians in this field according to actual needs, and is generally set to 120%.

[0044] Fire accidents may lead to secondary accidents such as explosions, building collapses, and harmful gas leaks. The emergency rescue materials for fire accidents set in the target emergency plan may not be able to cope with these secondary accidents. Therefore, it is necessary to calculate the types and total amount of missing emergency materials based on the accident simulation results, and then multiply them by the preset surplus ratio to increase the fault tolerance space. Finally, it is determined to replenish emergency materials and assign idle emergency teams to send them to the accident site and participate in the rescue. This design effectively improves the speed and intensity of rescue.

[0045] In one example, if the accident type is a harmful gas leak, the operation and maintenance center first determines the direction of the accident spread based on the wind direction information in the dynamic data table of the grid unit where the accident occurred, and the building information in the static data table of the grid unit where the accident occurred and its neighboring grid units. Wind can promote the spread of leaked harmful gases, and wind direction affects the direction of the spread of harmful gas leak accidents. Buildings can block the leakage of harmful gases to a certain extent. When performing accident simulations, the wind direction and building information are used as the simulation benchmarks to well deduce the direction of the spread of harmful gas leak accidents. Subsequently. The operation and maintenance center determines the speed of the accident spread based on the wind speed information, humidity information, and temperature information in the dynamic data table of the grid unit where the accident occurred. Wind speed and temperature are positively correlated with the speed of the spread of harmful gas leak accidents, while humidity is negatively correlated with the speed of the spread of harmful gas leak accidents. Therefore, when performing accident simulations, the wind speed, temperature, and humidity information are comprehensively considered to well deduce the speed of the spread of harmful gas leak accidents. Based on the direction of the accident spread and the speed of the accident spread, the operation and maintenance center simulates the corresponding accident spread range within the first preset time. After that, the operation and maintenance center simulates the probability and type of secondary accidents of harmful gas leakage corresponding to the first preset time based on the hazardous chemical information in the static data table of the grid unit where the accident occurred and the hazardous chemical information in the static data table of each grid unit within the scope of the accident spread. Harmful gas leakage accidents may cause secondary accidents such as explosion accidents, fire accidents, and water pollution accidents. Finally, the operation and maintenance center simulates the number of injuries corresponding to the first preset time based on the number of people in the dynamic data table of each grid unit within the scope of the accident spread, the proportion of injuries in harmful gas leakage accidents, and the proportion of injuries corresponding to the type of secondary accidents of harmful gas leakage. The proportion of injuries in harmful gas leakage accidents is composed of the proportion of falls, the proportion of inhalation of harmful gases, and the proportion of hypoxia.

[0046] In one example, if the accident type is a hazardous gas leak, the operation and maintenance center needs to determine the types and total amount of emergency supplies required to completely resolve the hazardous gas leak accident based on the scope of the accident, the probability of a secondary hazardous gas leak accident, the type of secondary hazardous gas leak accident, and the number of injured people. Then, based on the types and total amount of emergency supplies required to completely resolve the hazardous gas leak accident, and the types and total amount of emergency supplies corresponding to the target emergency plan, determine the types and total amount of emergency supplies shortfalls, and multiply the types and total amount of emergency supplies shortfalls by the preset inventory surplus ratio to determine the types and total amount of supplementary emergency supplies. The preset inventory surplus ratio can be set by a technician in this field according to actual needs, and is generally set to 120%.

[0047] Harmful gas leakage accidents may lead to secondary accidents such as explosions, fires, and water pollution accidents. The emergency rescue materials for harmful gas leakage accidents set in the target emergency plan may not be able to cope with these secondary accidents. Therefore, it is necessary to calculate the types and total amount of missing emergency materials based on the accident simulation results, and then multiply them by the preset surplus ratio to increase the fault tolerance space. Finally, it is necessary to determine the replenishment of emergency materials and assign idle emergency teams to send them to the accident site and participate in the rescue. This design effectively improves the speed and intensity of rescue.

[0048] Step 105, assigning idle emergency teams to rush to the vicinity of the accident location with additional emergency supplies.

[0049] In specific implementation, after the operation and maintenance center determines the replenishment of emergency supplies, it immediately assigns idle emergency teams to rush to the vicinity of the accident site with the replenishment of emergency supplies.

[0050] In one example, if the operation and maintenance center determines that the accident level is greater than the preset controllable level, it is necessary to assign the emergency team corresponding to the target emergency plan to carry the emergency materials corresponding to the target emergency plan to the accident location, and at the same time assign the saturation rescue emergency team to carry the saturation rescue emergency materials to the accident location. When the accident level of the accident is greater than the preset controllable level, the uncertainty in the rescue process is greatly increased. The emergency materials set in the target emergency plan are likely to be insufficient, and it takes a certain amount of time to replenish and dispatch emergency materials based on accident simulation. Therefore, once it is detected that the accident level of the accident is greater than the preset controllable level, the saturation rescue is immediately initiated, and the saturation rescue emergency team is assigned to carry the saturation rescue emergency materials to the accident location to participate in the rescue, so as to save the lives of the affected people and the property safety of the industrial park to the greatest extent.

[0051] In one example, after the operation and maintenance center assigns idle emergency teams to rush to the vicinity of the accident location with supplementary emergency supplies, it is also necessary to conduct an accident simulation again based on the static data tables and dynamic data tables of each grid unit within the accident spread range, the emergency supplies corresponding to the target emergency plan, and the supplementary emergency supplies, simulate the corresponding accident spread range within the second preset time, the probability of a secondary accident and the number of injured, and determine the secondary supplementary emergency supplies in combination with the emergency supplies and supplementary emergency supplies corresponding to the target emergency plan, and finally assign idle emergency teams to rush to the vicinity of the accident location with the secondary supplementary emergency supplies.
