Technical Field

[0001] This disclosure relates to the field of power plant emergency command technology, specifically to a power plant emergency command method and system. Background Technology

[0002] During power plant operation, there are emergencies caused by unit and equipment failures as well as natural disasters. When an emergency occurs, the DCS (Distributed Control System) monitors generate a large number of alarm signals, making it impossible to determine the accurate target emergency plan from among numerous emergency plans. Furthermore, the workload for team leaders in notifying all employees and leaders is heavy, and dispatching at all levels is time-consuming and laborious. At the same time, in terms of related technologies, the emergency intelligent system obtains information from the accident site through hardware, which is too limited to hardware monitoring and is prone to misjudgment of the situation. Summary of the Invention

[0003] To overcome the problems existing in related technologies, the purpose of this disclosure is to provide a method and system for emergency command in power plants.

[0004] According to a first aspect of the present disclosure, an emergency command method for a power plant is provided, applied to an emergency command platform, the method comprising:

[0006] The weather hazard level is determined based on the meteorological information collected by the weather instrument.

[0007] Based on the accident risk level and the weather hazard level, the accident emergency plan is invoked from the emergency plan.

[0008] According to the emergency response plan, the user interface of the emergency command platform displays accident information related to the accident, and sends emergency alarm information to intranet terminals connected to the emergency command platform according to the preset calling system.

[0009] Optionally, the step of displaying accident information related to the accident through the user interface of the emergency command platform according to the accident emergency plan includes:

[0012] The location information of the intranet terminal connected to the emergency command platform is invoked;

[0013] The target danger zone is adjusted in real time based on images captured by cameras within the target danger zone, the positioning information, and the PI accident information.

[0014] Based on the images captured by the cameras corresponding to each identified target danger area, the location information, and the 3D map, accident information corresponding to the target danger area is generated and displayed through the user interface of the emergency command platform.

[0015] Optionally, adjusting the target danger zone in real time based on images captured by cameras within the target danger zone, the positioning information, and the PI accident information includes:

[0016] Based on the images captured by the cameras within the target danger zone, the positioning information, and the PI accident information, the target danger zone is adjusted once.

[0017] The target danger zone after the first regional adjustment is displayed on the user interface of the emergency command platform;

[0018] In response to an operation on the user interface targeting the target hazard area after the first regional adjustment, a second regional adjustment is performed on the target hazard area to obtain the adjusted target hazard area.

[0019] Optionally, the emergency alarm information includes:

[0020] The paging signal and key information for contingency plan processing sent to intranet terminals within the target danger zone; and,

[0021] An audible and visual alarm is sent to intranet terminals that are at a distance that meets a preset distance threshold from the target danger zone.

[0022] Optionally, according to the emergency response plan, emergency alarm information is sent to intranet terminals connected to the emergency command platform according to a preset call system, including:

[0023] According to the aforementioned emergency response plan, the shift leader's terminal is determined from the intranet terminals corresponding to the on-duty employees according to the preset call system.

[0024] Send an activation request for the emergency response plan to the duty officer's terminal;

[0025] In response to the confirmation information sent by the duty officer terminal for the activation request, an emergency alarm information corresponding to the accident emergency plan is sent to the intranet terminal connected to the emergency command platform.

[0026] Optionally, before determining the risk level of an accident based on target accident image information captured by cameras installed within the power plant and PI accident information obtained from the management area server, the following steps are included:

[0027] Based on the image information collected by any of the cameras installed in the power plant, and / or based on the PI accident information obtained by the management area server, it is determined whether an accident has occurred;

[0028] In the event that an accident has been determined, the target accident image information is retrieved from the image information captured by the camera, and / or, the PI accident information is retrieved from the PI accident information obtained from the management area server.

[0029] Optionally, determining the accident risk level based on target accident image information collected by cameras installed within the power plant and PI accident information obtained from the management area server includes:

[0030] Based on the target accident image information collected by the cameras installed in the power plant, the target image in the target accident image information is compared with the accident contingency plan image through the AI ​​(Artificial Intelligence) algorithm to determine the first accident level;

[0031] Based on the PI accident information obtained from the management area server, the AI ​​algorithm is used to analyze the device information, device operating parameters, and device alarm information related to the target image in the PI accident information to determine the second accident level;

[0032] The accident risk level is determined based on the first accident level and the second accident level.

[0033] Optionally, the intranet terminal is used to match and bind with personal information, and the intranet terminal has at least one of the following functions: automatic check-in, photo taking, video recording, paging, intercom, positioning, and information uploading.

[0034] According to a second aspect of the present disclosure, a power plant emergency command system is provided. The system includes production area monitoring equipment, a management area server communicatively connected to the production area monitoring equipment, an emergency command platform as described in the first aspect of the present disclosure communicatively connected to the management area server, and a camera, a weather instrument, and an intranet terminal communicatively connected to the emergency command platform.

[0035] The camera is used to collect image information of target accidents within the power plant;

[0036] The weather instrument is used to collect meteorological information;

[0037] The production area monitoring equipment is used to detect and store equipment information, equipment operating parameters and equipment alarm information of the equipment in the power plant.

[0038] The management area server is used to receive equipment information, equipment operating parameters and equipment alarm information sent by the monitoring equipment in the production area, perform data analysis, and send the analyzed PI accident information to the emergency command platform.

[0039] The emergency command platform is used to execute the power plant emergency command method described in the first aspect of this disclosure;

[0040] The intranet terminal is used to receive emergency alarm information sent by the emergency command platform.

[0041] Optionally, the production area monitoring equipment includes: a PI server and multiple operator stations communicatively connected to the PI server;

By combining accident information obtained from hardware monitoring and software monitoring, the judgment of accident risk level is more accurate, thereby enabling the recall of more targeted accident emergency plans. This greatly improves the safety and reliability of the power plant emergency command system and avoids losses caused by misjudgment.

[0046] Other features and advantages of this disclosure will be described in detail in the following detailed description section. Attached Figure Description

[0053] Figure 6 This is a schematic diagram of the structure of a power plant production area and management area according to an exemplary embodiment. Detailed Implementation

[0054] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0055] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0056] The purpose of this disclosure is to provide a power plant emergency command method and system to address the technical problems in related technologies, such as the overly simplistic information acquisition methods of emergency command systems, which rely solely on hardware monitoring, making it easy to misjudge accident situations and cause greater losses or resource waste, and the inability to monitor and store the entire process due to the large number of alarm messages.

[0057] Figure 1 This is a flowchart illustrating an emergency command method for a power plant according to an exemplary embodiment. This disclosure provides an emergency command method for a power plant, applied to an emergency command platform. See also... Figure 1 As shown, the method includes:

[0058] S1. Determine the accident risk level based on the target accident image information collected by the cameras installed in the power plant and the PI accident information obtained by the management area server.

[0059] The power plant is equipped with multiple cameras, covering important entrances and exits, main roads, key areas, and important equipment. The emergency command platform can communicate with the cameras installed in the power plant via a wired network.

[0060] For example, key areas include the main plant area, power distribution area, coal-fired facilities area, auxiliary production facilities area, living area, and construction area. Key equipment includes boilers, cooling towers, various pipelines, and pumps. Key roads include emergency evacuation routes and main fuel transport routes. Key entrances and exits include the power plant entrances and exits, the entrances and exits to the construction area within the power plant, and the entrance and exit to the power plant's main control room.

[0061] The emergency command platform compares and analyzes the accident image information captured by the camera with the preset image information through AI algorithms. The analysis results are then compared and analyzed with the PI accident information obtained from the management area server to determine the accident risk level.

[0062] PI incident information includes equipment information, equipment operating parameters, and equipment alarm information obtained by the management area server from the living area. The living area includes operator stations for monitoring equipment information, equipment operating parameters, and equipment alarm information, and a PI server for storing information.

[0063] S2. Determine the weather hazard level based on the meteorological information collected by the weather instrument.

[0064] It is worth mentioning that the meteorological information collected by the weather instrument includes at least one of the following: ambient temperature, ambient humidity, wind speed, and rainfall. The AI ​​algorithm determines meteorological factors based on the meteorological information, compares and analyzes the meteorological factors with preset meteorological factors, and determines the weather hazard level based on the analysis results.

[0065] S3. Based on the accident risk level and weather hazard level, invoke the accident emergency plan from the emergency plan.

[0066] It is worth noting that in the absence of an accident, i.e., when the accident risk level is 0, and in the absence of severe weather, i.e., when the weather hazard level is 0, there is no need to determine an accident emergency plan. However, in the event of an accident and / or severe weather, the accident emergency plan will be invoked from the emergency plan based on the determined accident risk level and weather hazard level.

[0067] In one embodiment, if an accident occurs in the main plant area with an accident risk level of 2, requiring the evacuation of personnel, and if the weather information indicates no severe weather, the weather hazard level is determined to be 0. Furthermore, based on the accident risk level of 2 and the weather hazard level of 0, the corresponding first emergency response plan is activated. If the weather information indicates heavy rain, with a weather hazard level of 2, the difficulty of personnel evacuation increases, and personnel are required to inspect the power distribution facilities. Furthermore, based on the accident risk level of 2 and the weather hazard level of 2, the corresponding second emergency response plan is activated. The second emergency response plan has a higher handling level than the first emergency response plan.

[0068] S4. According to the emergency response plan, display accident-related information through the user interface of the emergency command platform, and send emergency alarm information to the intranet terminals connected to the emergency command platform in accordance with the preset call system.

[0069] In this embodiment of the disclosure, the intranet terminal can be, for example, a smartphone, wearable device, tablet computer, etc., and the intranet terminal communicates with the emergency command platform through a wireless network.

[0070] Accident-related information includes: the target danger zone, the 3D map corresponding to the target danger zone, the image information of the area corresponding to the target accident image information, and personnel location information.

[0071] In one embodiment, if a boiler tube explosion occurs in the boiler plant, according to the emergency response plan, the user page of the emergency command platform displays on-site images of the pipeline where the explosion or steam leakage occurred, equipment information of the boiler tube, historical maintenance information, boiler tube operation information, and information of on-site personnel. A confirmation request is sent to the shift leader according to the call system. After confirmation by the shift leader, an emergency alarm message is sent to intranet terminals such as mobile phones, computers, and tablets to notify relevant technical personnel to take emergency shutdown measures and other personnel to evacuate safely.

[0072] The above solution achieves the following technical effects: by acquiring accident information from multiple sources through hardware and software monitoring, the judgment of accident type and risk level becomes more accurate, thereby enabling the recall of more targeted emergency response plans, greatly improving the safety and reliability of the power plant's emergency command system, and avoiding losses caused by misjudgment.

[0073] Hardware monitoring involves collecting target image information through cameras and weather information through meteorological instruments, while software monitoring involves obtaining PI accident information through the management area server.

[0074] Optionally, Figure 2 This is an implementation illustrated according to an exemplary embodiment. Figure 1The flowchart for method S4 shows that, according to the emergency response plan, S4 displays accident-related information through the user interface of the emergency command platform, including:

[0075] S41. Based on the location information of the camera that sends the target accident image information, determine the target danger zone and retrieve the corresponding 3D map of the target danger zone.

[0076] Based on the functions of the plant and the work requirements, the power plant is divided into multiple functional areas, including the main plant area, the power distribution equipment area, the coal-fired facilities area, the auxiliary production facilities area, the living area, and the construction area. Each area has multiple cameras.

[0077] The emergency command platform stores 3D maps of various functional areas. If one or more cameras in a functional area capture target image information, the functional area is designated as a target danger zone, and the 3D map of the functional area is displayed on the user interface of the emergency command platform.

[0078] S42. According to the emergency response plan, adjust the acquisition angle of the cameras in the target danger area so that all cameras in the target danger area are aimed at the area corresponding to the target accident image information for image acquisition.

[0079] Different types of cameras are installed in different areas. For example, cameras with a small monitoring angle but a long monitoring distance are used in the fuel transport main road, cameras with a large monitoring angle but a short monitoring distance are used in the main control room entrance, and more durable industrial cameras are used in the coal-fired facility area. All cameras are preset with one or more viewing angles according to the actual field of view. For example, cameras located at the corner of the office area corridor or at the warehouse door have only one viewing angle, while the employee passage between the coal-fired equipment area and the steam and water equipment area has two viewing angles.

[0080] According to the emergency response plan, all cameras within the target danger zone adjust their camera angles according to preset viewing angles, so that all cameras are aimed at the area corresponding to the target accident image information. If there is only one preset viewing angle, the camera angle remains unchanged.

[0081] S43. Invoke the location information of the intranet terminal connected to the emergency command platform.

[0082] The management area server, emergency command platform, cameras, weather instruments, and intranet terminals can all be connected via 5G intranet communication.

[0083] Internal network terminals can include mobile phones, paging devices, computers, etc., and each internal network terminal is uniquely bound to personal information.

[0084] S44. Adjust the target danger zone in real time based on the images, positioning information and PI accident information collected by the camera in the target danger zone.

[0085] Based on the images, location information, and 3D maps captured by the cameras corresponding to each identified target danger area, accident information corresponding to that target danger area is generated and displayed through the user interface of the emergency command platform.

[0086] Figure 3 This is an implementation illustrated according to an exemplary embodiment. Figure 2 The S44 method flowchart describes how the target hazard area is adjusted in real time based on images, positioning information, and PI accident information captured by cameras within the target hazard area. This can be implemented through the following steps:

[0087] S441. Based on the images, positioning information, and PI accident information collected by the cameras within the target hazardous area, make an area adjustment for the target hazardous area.

[0088] The target danger zone is the functional area where the camera that first captured the target accident image information is located. The AI ​​system analyzes the image information, positioning information, and PI accident information in real time. The image information includes the image information captured by all cameras within the target danger zone. If the AI ​​system determines that the accident is expanding or there is a possibility of the accident expanding, it expands the scope of the target danger zone. If the AI ​​system determines that the accident is decreasing or the accident has stopped, it shrinks the scope of the target danger zone.

[0089] For example, if a fire occurs in the combustion equipment area, after the cameras in the combustion equipment area capture target image information, the emergency command platform will designate the combustion equipment area as a target danger zone. The AI ​​algorithm will analyze the equipment information, equipment operating parameters, and equipment alarm information in the PI accident information to determine that some combustion equipment may have the risk of the accident spreading or affecting other functional areas. Furthermore, based on the location information of the power plant staff, the platform will confirm the number of staff in the target danger zone and the number of staff whose distance from the target danger zone meets the preset distance threshold, and analyze the risk of personnel evacuation blockage. Based on the above analysis results, the emergency command platform will expand the scope of the target danger zone.

[0090] S442. Display the target danger zone after the area adjustment on the user interface of the emergency command platform.

[0091] S443. In response to an operation on the user interface targeting the target hazardous area after a first-time area adjustment, perform a second-time area adjustment on the target hazardous area to obtain the adjusted target hazardous area.

[0092] It is worth noting that operators can readjust or confirm the scope of the target danger zone after the first regional adjustment based on the target image information, PI accident information, and intranet terminal location information to obtain the adjusted target danger zone. The adjusted target danger zone can be adjusted again according to the actual situation.

[0093] For example, if a mechanical failure occurs in the main plant area, and the cameras in the main plant area capture target image information, the emergency command platform will designate the main plant area as the target danger zone. Based on the equipment information, equipment operating parameters, and equipment alarm information in the PI accident information, the AI ​​algorithm will analyze that the impact range of this accident is smaller than the target danger zone. Furthermore, the emergency command platform will narrow down the target danger zone and display it on the user interface of the emergency command platform. Operators can communicate with the personnel at the accident site through the intranet to understand the real-time situation of the accident, and confirm the adjustment of the target danger zone based on the PI accident information displayed on the user page of the emergency command platform, or make further adjustments to the target danger zone.

[0094] Optionally, according to the emergency response plan, emergency alarm information is sent to intranet terminals connected to the emergency command platform according to a preset call system, including:

[0095] According to the emergency response plan, the shift leader's terminal is determined from the internal network terminals corresponding to the employees on duty that day, in accordance with the preset call system.

[0096] The emergency command platform has multiple emergency response plans for various accident risk levels and weather hazard levels. Based on the magnitude and scope of the hazards corresponding to the accident risk level and weather hazard level, as well as the personnel deployment of the emergency response plan, the emergency response plans are divided into multiple levels, including basic emergency response plans, intermediate emergency response plans, and advanced emergency response plans.

[0097] Employees at the power plant clock in and out via an intranet terminal. The clock-in information determines all employees on duty that day. Among all employees on duty that day, shift leaders are assigned to different levels based on their job positions. Different levels of shift leaders correspond to different levels of emergency response plans. Emergency response plans can only be activated after the corresponding shift leader confirms the activation request. Shift leader levels include junior shift leader, intermediate shift leader, and senior shift leader.

[0098] Send an application to the shift leader's terminal to activate the emergency response plan.

[0099] In response to the confirmation message sent by the shift leader terminal for the activation request, emergency alarm information corresponding to the accident emergency plan is sent to the intranet terminal connected to the emergency command platform.

[0100] In one embodiment, when the auxiliary production facility area of ​​the power plant loses power, the emergency response plan is determined to be a basic emergency response plan based on the analysis results of the AI ​​algorithm. The emergency command platform initiates the process by sending an activation request for the basic response plan to the terminal of the primary duty officer. After the primary duty officer's terminal confirms the activation request, the intranet terminal connected to the emergency command platform sends emergency alarm information corresponding to the basic emergency response plan.

[0101] In another embodiment, a fire breaks out in the main plant area of ​​the power plant. According to the analysis results of the AI ​​algorithm, the emergency response plan is a high-level emergency response plan. The emergency command platform initiates the process by sending an activation request for the high-level response plan to the terminal of the high-level duty officer. After the high-level duty officer confirms the activation request at the terminal, the intranet terminal connected to the emergency command platform sends emergency alarm information corresponding to the basic emergency response plan.

[0102] Optionally, the emergency alarm information includes:

[0103] The paging signals and key information for contingency planning sent to intranet terminals within the target danger zone.

[0104] An audible and visual alarm is sent to intranet terminals that are within a preset distance threshold from the target danger zone.

[0105] It is worth noting that when an accident occurs, all intranet terminals within the target danger zone will receive a paging signal and key information for emergency response. The paging signal is used to remind staff within the target danger zone to evacuate or to inform them of emergency response procedures. The key information for emergency response includes evacuation routes, accident type, accident risk level, and key emergency response information.

[0106] In one embodiment, the preset distance threshold is 15 to 20 meters. If the distance between the staff outside the target danger zone and the target danger zone is within the preset threshold range, the intranet terminal will receive an alarm command. The alarm command is used to make the intranet terminal that receives the alarm command start an audible and visual alarm to remind the staff to stay away from the target danger zone.

[0107] Optionally, before determining the risk level of an accident based on target accident image information collected by cameras installed within the power plant and PI accident information obtained from the management area server, the following steps are included:

[0108] Based on image information collected by any camera installed within the power plant, and / or based on PI accident information obtained from the management area server, it is determined whether an accident has occurred.

[0109] In the event that an accident has been determined, the target accident image information is retrieved from the image information captured by the camera, and / or the PI accident information is retrieved from the PI accident information obtained from the management area server.

[0110] In one embodiment, the emergency command platform obtains PI accident information through the management area server. However, the management area server does not receive PI accident information sent from the production area. After comparing and analyzing the target accident image information and preset image information through AI algorithm, the platform determines whether the accident has occurred based on the analysis results of the target accident image information. If the accident is determined to have occurred, the emergency command platform immediately calls the PI accident information corresponding to the target accident image information. If the accident is determined not to have occurred, the emergency command platform maintains the current state.

[0111] In another embodiment, the emergency command platform obtains PI (Problem Injury) incident information through the management area server, but the cameras installed within the power plant do not capture target incident image information. After analyzing the PI incident information using AI algorithms, the platform confirms whether an incident has occurred based on the analysis results. If an incident is confirmed, the emergency command platform immediately retrieves the target image information captured by the cameras installed within the power plant corresponding to the PI incident information. If an incident is confirmed not to have occurred, the emergency command platform maintains its current state.

[0112] In another embodiment, the emergency command platform obtains PI (Problem Injury) incident information through the management area server. AI algorithms are used to analyze the target incident image information and the PI incident information. Based on the analysis results, it is determined whether an incident has occurred. If an incident is determined to have occurred, the risk incident level is determined based on the analysis results. If an incident is determined not to have occurred, the emergency command platform maintains its current state.

[0113] Optionally, Figure 4 This is an implementation illustrated according to an exemplary embodiment. Figure 1 See the flowchart of method S1 in the middle. Figure 4 As shown, based on the target accident image information collected by cameras installed within the power plant and the PI accident information obtained from the management area server, the accident risk level is determined, including:

[0114] S11. Based on the target accident image information collected by the cameras installed in the power plant, the target image in the target accident image information is compared with the accident contingency plan image through AI algorithm to determine the first accident level.

[0115] To more clearly describe the solutions provided in the embodiments of this application, please refer to... Figure 5 As shown, the aforementioned step S11 can be implemented through the following detailed steps:

[0116] S111. Determine whether the target hazard features exist from the preset hazard features based on the target accident image analysis.

[0117] The preset hazard characteristics include at least one of the following: fire, water overflow, gas leak, power outage, and information about unfamiliar personnel.

[0118] S112. If the target accident image has dangerous features, the location and time of the accident shall be confirmed based on the acquisition time of the target accident image information and the location of the camera that acquired the target accident image.

[0119] S113. Based on the area where the accident occurred and the time of the accident, determine the target time period to which the accident occurred, and retrieve the preset image information corresponding to the target time period and the accident location. The preset image information has a one-to-one correspondence with the target time period and the accident location.

[0120] The preset image information corresponding to the accident occurrence time and location includes first preset image information and second preset image information. The first preset image information is: preset image information for a time period corresponding to the accident occurrence location and time when no accident has occurred. For example, if the accident occurrence time of the target image information is 3 PM, then the image information from 1 PM to 6 PM in the corresponding preset image will be used; if the accident occurrence time of the target image information is 2 AM, then the image information from 1 AM to 6 AM in the corresponding preset image will be used. The second preset image information is: image information for a time period corresponding to the accident occurrence location and time from historical accident image information. Historical accident image information includes image information of all relevant accidents that have occurred in all factories of the same type.

[0121] S114. Compare and analyze the preset image information and the target accident image information to verify whether the accident has occurred.

[0122] For example, in the target image information of the boiler room, the glass tube of the water level gauge appears white and the water level gauge is stationary with no slight fluctuations, indicating a false water level phenomenon. This matches the characteristics of a boiler water shortage accident in the preset hazard features. The AI ​​algorithm analyzes and determines that there are hazard features in the target image information. The target accident image information was collected at 3:00 AM, and the camera that collected the target accident image was located above the water level gauge in area A of the boiler room. The AI ​​algorithm analyzes and determines that the accident occurred in area A of the boiler room at 3:00 AM. Based on this information, the first and second preset image information from 1:00 AM to 6:00 AM are called up for analysis and comparison, verifying that there is indeed a water shortage accident in the boiler room.

[0123] S115. If an accident is confirmed to have occurred, the first accident level shall be determined based on the analysis results.

[0124] The first accident level is the accident risk level analyzed only from the target image information. The actual accident risk level can only be determined based on the analysis results of the PI accident information.

[0125] See also Figure 4 As shown, S12, based on the PI accident information obtained from the management area server, the AI ​​algorithm is used to analyze the device information, device operating parameters and device alarm information related to the target image in the PI accident information to determine the second accident level.

[0126] S13. Determine the accident risk level based on the first accident level and the second accident level.

[0127] In one embodiment, the emergency command platform obtains PI accident information through the management area server. However, the management area server does not receive PI accident information sent from the production area. After comparing and analyzing the target accident image information and preset image information, the AI ​​algorithm determines the first accident level based on the analysis results of the target accident image information. The emergency command platform immediately calls the PI accident information corresponding to the target accident image information and analyzes the PI accident information through the AI ​​algorithm. Based on the analysis results of the PI accident information, the second accident level is confirmed. Based on the first accident level and the second accident level, the accident risk level is determined.

[0128] In another embodiment, the emergency command platform obtains PI accident information through the management area server, but the cameras installed in the power plant do not capture target accident image information. After the AI ​​algorithm analyzes the PI accident information, it confirms the second accident level based on the analysis results. The emergency command platform immediately calls the target image information obtained by the cameras installed in the power plant corresponding to the PI accident information. After comparing and analyzing the target accident image information with the preset image information, the AI ​​algorithm determines the first accident level based on the analysis results of the target accident image information. Based on the first accident level and the second accident level, the accident risk level is determined.

[0129] In another embodiment, the emergency command platform obtains PI accident information through the management area server. After the AI ​​algorithm compares and analyzes the target accident image information and the preset image information, it determines the first accident level based on the analysis results of the target accident image information.
