[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] This embodiment introduces a multi-department emergency plan joint simulation system for emergency events. Figure 1 As shown,

[0037] The system architecture of the present invention mainly includes: a login module, a plan setting module, an emergency event setting module, a plan simulation module, an expert evaluation module and a desktop simulation real-time display module.

[0038] The login module includes a coach login terminal, a trainer login terminal and an evaluation expert login terminal;

[0039] The coach login terminal is used for the coach to log in to the simulation system to determine emergency events and issue task instructions;

[0040] The training personnel login terminal is used for the training personnel to log in to the simulation system and select the simulation department to which the training personnel belongs and receive the task instructions;

[0041] The evaluation expert login terminal is used for the evaluation expert to log in to the deduction simulation system to evaluate the deduction results.

[0042] Specifically, the login module of this embodiment is used for trainers, coaches and evaluation experts to log in and out of the simulation system; wherein the coach uses the login module to make a selection to determine the emergency event for which the plan simulation will be carried out; the trainer uses the login module to select the simulation department to which the trainer belongs and receive the task instruction. The emergency event for which the plan simulation will be carried out determined by the coach requires trainers from multiple simulation departments to jointly conduct simulations, and requires trainers from multiple simulation departments to conduct subsequent simulations according to the task instruction at the same time.

[0043] like Figure 2 The operation process of this embodiment is shown as the first step. The trainer, coach and evaluation expert log in to the login module. The coach selects the emergency event to be simulated, and the system automatically loads the static process of the emergency event. Then the coach sets the risk factor of the emergency event, the type and number of dangerous molecules in the emergency event, the type and number of personnel available in different departments and other parameters through the emergency event setting program. Then the coach can set the emergency plans that can be used by each department, the impact parameters of the types and number of emergency plan jobs on the emergency event through the plan setting program; after logging in, the trainer selects the department for joint simulation and sends the selection result to the plan simulation program; after entering the evaluation expert system, the evaluation expert can set the evaluation parameters, and finally generate an evaluation strategy configuration file and send it to the simulation performance evaluation program.

[0044] The emergency event setting module is used to issue an emergency event instruction after the coach logs into the simulation system, and to set the emergency event parameters of the simulation department according to the emergency event instruction;

[0045] Preferably, the emergency event parameters of the simulation department include the types of materials that the training personnel of the simulation department can control, the maximum amount of the materials, the types of personnel that the training personnel of the simulation department can control, the maximum number of people in each type of work, the risk factor of the emergency event, the number of dangerous elements of the emergency event (people who cause the emergency event), and the initial evolution speed of the emergency event. Specifically, the emergency event setting module can generate an emergency event parameter configuration file according to the set emergency event parameters.

[0046] The emergency plan setting module is used to set the emergency plan parameters of the simulation department according to the emergency event instruction after the coach logs into the simulation system;

[0047] Preferably, the emergency plan parameters of the simulation department include: types of emergency plans, types of work required for the types of emergency plans, the minimum number of people corresponding to the types of work required for the types of emergency plans, types of materials required for the types of emergency plans, and the minimum number of emergency materials corresponding to the types of materials required for the types of emergency plans; parameters affecting the types of work required for the types of emergency plans and the number of people corresponding to the types of work required for the types of emergency plans on emergency events, parameters affecting the types of materials required for the types of emergency plans and the number of emergency materials corresponding to the types of materials required for the types of emergency plans on emergency events, parameters affecting the types of emergency plans on the evolution of emergency events, and parameters affecting the types of emergency plans of the simulation department on other simulation departments and plans; specifically, the plan setting module can generate an emergency plan parameter configuration file based on the set emergency plan parameters.

[0048] The emergency plan simulation module is used for the training personnel to set the emergency plan type according to the simulation department to which the training personnel belongs, and to set the actual parameters of the simulation process according to the emergency event parameters of the simulation department, so as to obtain the emergency event evolution coefficient and then obtain the emergency plan evolution speed;

[0049] When an emergency event reaches the emergency event evolution condition (the evolution speed is greater than or equal to the emergency event threshold), the training personnel reset the type of emergency plan to simulate the emergency event that reaches the emergency event evolution condition; or when the emergency event reaches the set emergency event end condition, the simulation process of the emergency event is completed. Figure 3 As shown;

[0050] Preferably, the emergency event evolution coefficient is obtained as follows:

[0051] a t+1 =a t +ES×T step

[0052]

[0053]

[0054] Where: a t+1 represents the emergency event evolution coefficient in the t+1th time period; a t represents the evolution coefficient of the emergency event in the tth time period; ES represents the actual evolution speed of the emergency event; T step Indicates the time step; ES init Indicates an emergency event; N y Indicates the total number of plans; i indicates the plan number; ES Yi represents the impact parameter of plan i on the emergency event; t represents the time period number; represents the total number of material types included in plan i; j represents the number of material types used; represents the quantity of the jth material used in plan i; It represents the parameter affecting the evolution speed of each unit of the j-th material in plan i; Indicates the total number of types of work included in plan i; represents the number of workers in the oth type of work used in plan i; It represents the parameter of influence of each worker in the oth type of work used in plan i on the material evolution speed; o represents the number of the type of work;

[0055] Specifically, the plan deduction module is responsible for the real-time deduction of emergency plan parameters, initializes the emergency plan deduction program according to the emergency event parameter configuration file, the emergency plan parameter configuration file and the input emergency event options, and implements the deduction according to the input of the training personnel to implement the emergency plan. The training personnel need to implement the emergency plan according to the emergency event and arrange the corresponding manpower and material resources. The module performs real-time deduction of the emergency event according to the emergency plan and related parameter inputs, the emergency event parameter configuration file and the emergency plan parameter configuration file, and calculates the emergency event deduction coefficient. If the emergency event reaches the end condition, the emergency event plan deduction ends and sends the generated plan deduction result to the expert evaluation module. If the emergency event reaches the evolution condition, a new emergency event occurs.

[0056] Preferably, the emergency plan evolution condition is:

[0057] ET≤ES

[0058] Where: ET represents the threshold of emergency event evolution; ES represents the evolution speed of emergency event;

[0059] Specifically, the emergency plan termination conditions in this embodiment are:

[0060]

[0061] Wherein, NumJ is the total number of end conditions, J is the number of the judgment condition, and f(J) is the parameter representing the real-time calculation of the Jth judgment condition of the current emergency event. This parameter has particularity and is calculated differently for different events. The judgment condition parameter calculation formula is as follows:

[0062]

[0063] Specifically, in the subway fire case, the total number of judgment conditions NumJ = 2, where:

[0064] The judgment condition for f(1) to be met is:

[0065] Da+Dr=NumD

[0066] Where: Da is the number of suspects captured, Dr is the number of dangerous elements who have escaped, and NumD is the number of dangerous elements in the emergency event set by the coach.

[0067] The judgment condition for f(2) to be met is:

[0068] F ≤ 0 or F ≥ 2D

[0069] Where: F is the fire parameter. If F ≤ 0, the fire is extinguished; if F ≥ 2, the fire spreads and cannot be controlled. Specifically, when 0 < F ≤ 2, it is in a state where the judgment condition is not met, and at this time, the training personnel normally conduct推演 on the emergency event.

[0070] The expert evaluation module is used to obtain the total number of plans executed at the end of the emergency event and the actual parameters of the推演 process when the emergency event meets the end condition, including the number of work types for each plan, the number of people for each work type, the types of materials used for each plan, and the quantity of each type of material, and the evaluation personnel determine the evaluation parameters to obtain the joint推演 score of each department;

[0071] Specifically, the evaluation parameters include: the proportion parameter of the plan execution score of the推演 department, the proportion parameter of the推演 parameter score of the推演 department, the subjective score of the expert system of the推演 department, etc.

[0072] Specifically, the expert evaluation module is responsible for evaluating the results of the emergency event推演. Experts can enter this module through logging in to the system to change the evaluation settings and generate an evaluation strategy configuration file. This module calculates the emergency plan推演 score based on the input plan推演 results and the evaluation strategy configuration file, where the calculation of the emergency plan推演 score includes the calculation of the proportion of the emergency plan score and the calculation of the proportion of the推演 parameters, and finally generates the plan推演 score. As Figure 4 shown;

[0073] Preferably, the joint推演 score of the推演 department is obtained as follows:

[0074]

[0075] G b = Gy b × Gyper b + Gt b × Gtper b + Gsub b

[0076] Where: Gy b represents the emergency plan execution score of the b-th推演 department; NumY b represents the total number of emergency plans executed by the b-th推演 department; i represents the plan number; It represents the score of the bth simulation department in executing the ith emergency plan (set by the expert system); represents the execution efficiency score of the bth simulation department in executing the ith emergency plan; It represents the score of the bth simulation department for the type and quantity of work assigned by the ith emergency plan; It represents the score of the input materials and quantity of the bth simulation department in implementing the ith emergency plan; Gt represents the total score of the bth simulation department in executing the ith emergency plan; b Indicates the deduction results of the bth deduction department; NumT b represents the total number of actual parameters of the simulation process of the bth simulation department; The score representing the actual parameters of the pth group of the bth game department's game process (set by the expert system); represents the maximum value of the actual parameter of the pth group of simulation process in the bth simulation department; The maximum score coefficient representing the actual parameter of the pth group of the bth deduction department; represents the actual parameters of the game process at the end of the game of the bth game department; The score coefficient representing the actual parameter of the game process at the end of the game of the bth game department; G represents the total score of the actual parameters of the simulation process of the bth simulation department; b Gyper represents the joint simulation result of the bth simulation department; b Gtper represents the execution performance ratio parameter of the bth simulation department (set by the expert system); b Gsub represents the performance ratio parameter of the bth simulation department (set by the expert system); b represents the expert system subjective score of the bth deduction department (set by the expert system);

[0077] Preferably, the joint deduction simulation system of this embodiment also includes a desktop deduction real-time display module; the desktop deduction real-time display module is used to display the deduction process of emergency events in real time.

[0078] Specifically, this embodiment is based on 3DMax modeling, unity3D virtual reality development engine, and C# language for research and development. The simulation system architecture of this embodiment mainly includes: login module, plan setting module, emergency event setting module, plan simulation module, expert evaluation module and desktop simulation real-time display module. Figure 2 shown.

[0079] Specifically, during implementation, emergency events and joint simulation departments are determined, and then static processes for emergency events are formulated, and emergency plans and impact parameters for the events are formulated according to the responsibilities of different departments. 3Dmax is used to create models of related environments, characters, equipment, etc. for emergency events, and imported into the Unity3D engine through FBX format for real-time rendering. At the same time, C# programming is used to implement the emergency event simulation process. When the system enters the simulation program, such as Figure 3 The simulation program shown initializes the emergency event simulation program by obtaining the emergency event parameter configuration file, the static emergency event process and the emergency plan parameter configuration file. During the initialization, the emergency event plan simulation program dynamically modifies the static emergency event process simulation parameters according to the emergency event parameter configuration file and the emergency plan parameter configuration file, and at the same time initializes the emergency event plan desktop simulation to display the program scene in real time. Trainees from various departments can view the emergency event plan simulation situation and the emergency event virtual scene in real time.

[0080] The plan simulation program then enters the emergency event plan simulation calculation stage. In this stage, the plan simulation program performs calculations based on the emergency plans and related parameters arranged by each department. The emergency plans and related parameters arranged by each department are input by the trainees, including the implemented emergency plans, the types of work and number of people arranged by the emergency plans, and the materials and quantities arranged by the emergency plans.

[0081] During the emergency plan simulation calculation stage, the emergency event simulation coefficient and the emergency event evolution coefficient are calculated. The emergency event simulation coefficient and the emergency event evolution coefficient are calculated based on the emergency plan and related parameter inputs and the current state of the emergency event. When the emergency event evolution coefficient reaches the emergency event evolution condition, a new emergency event is evolved. If the emergency event simulation coefficient reaches the emergency event end condition, the emergency plan simulation ends, and the plan simulation results are output and sent to the simulation performance evaluation program.

[0082] When the system enters the evaluation process, such as Figure 4 As shown, the simulation results are evaluated according to the simulation results output by the simulation program and the evaluation strategy configuration file generated by the evaluation setting module, wherein the simulation results include emergency casualty parameters, emergency event evolution parameters, multi-department joint coordination parameters, emergency event simulation efficiency parameters, plan simulation resource calling parameters and emergency event completion degree. The emergency plan simulation result calculation calculates the emergency plan score ratio and the simulation parameter ratio of the plan simulation results according to the evaluation strategy configuration file, and finally generates the joint simulation results of the emergency plans of various departments, and displays and records them on the training personnel client and the coach client.

[0083] This embodiment takes the emergency handling department as the theme, conducts joint simulation of emergency plans of multiple departments for emergency events, combines virtual simulation and geographic information methods, and truly reproduces the process of the start, development, evolution, and termination of emergency events, and trains the division of labor and cooperation with other departments in personnel mobilization, material dispatch, and plan arrangement of commanders of various departments. At the same time, this system sets up emergency event setting procedures and plan setting procedures. Coaches can change the nature of emergency events according to the situation, increase the diversity of emergency events, and improve training effects. In addition, this system sets up an expert evaluation system, and can set evaluation strategies according to the expert system to enhance the focus of training.

[0084] Specifically, a specific workflow of this implementation is as follows:

[0085] 1. Each student (trainer) logs into the system and selects a role department, including five roles: on-site disposal department, fire department, emergency department, public security department, and emergency command center.

[0086] 2. The coach logs in to the coach system and selects a joint simulation emergency event such as "subway station arson incident". The parameters of the "subway station arson incident" are set, including the risk factor, number of dangerous elements, evolution events, and evolution speed of the emergency event. The number of casualties of the initial personnel and passengers in the incident is proportional to the risk factor, the number of dangerous elements is the number of suspects related to the emergency event, the evolution event is the evolution of the emergency event caused by the untimely handling of the current emergency event, the evolution speed of the emergency event determines the efficiency of the evolution of the emergency event, and the threshold of the evolution of the emergency event. In the current case, the coach sets the evolution event to "subway station explosion incident", the number of dangerous elements is 3, the risk factor is high, the evolution speed of the emergency event is the default parameter, and the complexity of the road conditions is high.

[0087] 3. The instructor sets the emergency plans that each joint exercise department can use and the minimum number of jobs or materials required for the plans through the instructor system, sets the types and quantities of jobs that each joint exercise department can use, and sets the types and quantities of materials that each joint exercise department can use. In the current case, the instructor sets all default emergency plans for each department, and sets the on-site disposal department to be equipped with 5 on-site disposal personnel, 2 sets of emergency fire extinguishing equipment, 1 set of emergency communication equipment, and 1 set of first aid materials; the fire department is equipped with 30 firefighters and 5 fire trucks; the first aid department is equipped with 15 first aid personnel, 3 ambulances, and 1 emergency helicopter; the public security department is equipped with 15 traffic police, 20 public security police, 20 armed police, 10 police cars, and 15 police motorcycles; the emergency command center is equipped with 5 on-site management personnel, 30 sets of on-site guarantee materials, 30 sets of life rescue guarantee materials, 10 engineering rescue professionals, 30 sets of engineering rescue disposal materials, and 5 rescue transport vehicles.

[0088] 4. Each department enters the plan simulation program and initializes the emergency events according to the instructor's settings. In the scenario, a fire occurs at subway station A and three suspects are escaping the scene disguised as ordinary people. There are five injured people at the scene, including two seriously injured and three slightly injured. There are 80 people in the subway to be evacuated. Then a multi-department joint emergency simulation begins.

[0089] 5. At T1, the on-site handling department role executes the plan to use emergency communication equipment to [report emergency events to the emergency command center]; instructs 2 on-site handling personnel to use 2 sets of emergency fire extinguishing equipment to [preliminary control of fire]; instructs 2 on-site handling personnel to carry out the [evacuation of passengers] plan; instructs 1 on-site handling personnel to use 1 set of first aid materials to carry out the [treatment of injured persons] plan. Specifically, if the [report emergency events to the emergency command center] plan is not carried out, other joint simulation departments cannot receive emergency event messages; if the [preliminary control of fire] plan is not carried out within a certain period of time, the fire spread parameter increases, increasing the speed of emergency event evolution; the implementation of the [evacuation of passengers] plan can speed up the evacuation speed parameter of the masses; the implementation of the [treatment of injured persons] plan can slightly reduce the probability parameter of death of seriously injured persons. Among the above parameters, either the spread parameter will increase the risk of injury to stranded people; the evacuation speed parameter of the masses will reduce the number of passengers in the subway station over time, and also speed up the escape of suspects; the probability parameter of death of seriously injured persons will cause the death of seriously injured persons over time.

[0090] 6. At T2, the emergency command center received news from the on-site handling department and conducted a joint exercise, and executed the [Emergency Event Notification] plan to the fire department, emergency department, and public security department; implemented the [Assignment of on-site management personnel] plan, assigned 5 on-site management personnel, and mobilized 1 emergency transport vehicle to transport the on-site management personnel to the scene; implemented the [Transportation of on-site materials] plan, assigned 10 engineering rescue professionals, mobilized 30 sets of on-site guarantee materials, 30 sets of life-saving materials, and 30 sets of engineering rescue materials to be transported to the scene; implemented the [Subway Suspension] plan to prevent the number of stranded passengers at the current subway station from increasing.

[0091] 7. At T3, the fire department, emergency department, and public security department received the emergency incident notification from the emergency command center, and executed [assigning personnel to the emergency command center] to form a joint leadership team to improve the joint handling efficiency parameters.

[0092] 8. The public security department implements the [Traffic Control] plan, assigns 5 traffic policemen and 5 police motorcycles, and increases the speed parameters of emergency vehicles passing through the road near Subway Station A; implements the [Emergency Police] plan, and 20 public security policemen, 20 armed policemen, and 10 police cars go to Subway Station A. The fire department implements the [Emergency Fire Alarm] plan, and 30 firefighters and 5 fire trucks go to Subway Station A. The emergency department implements the [Ambulance Emergency Rescue] plan, and 15 emergency personnel and 3 emergency vehicles go to Subway Station A.

[0093] 9. At T4, due to the high complexity of the road conditions, the leadership group of the emergency command center instructed the public security department to implement the [Traffic Escort] plan, assigning 10 traffic police and 10 police motorcycles to escort fire trucks and emergency vehicles to increase the speed of movement. After the on-site managers arrived at the scene, the emergency command center implemented the [On-site Emergency Disposal] plan, assigning 3 on-site managers to assist in the evacuation of passengers, 1 on-site manager to set up a warning area outside the subway station, and 1 on-site manager to find out whether the nearby area is available for helicopter takeoff and landing. If the nearby area is available for helicopter takeoff and landing, the emergency command center instructs the emergency department to implement the [Helicopter Ambulance Transfer of Severely Injured] plan. At this moment, the on-site managers assisted in the evacuation of passengers to increase the speed of the crowd evacuation and the speed of the suspect's escape; the on-site managers set up a warning area outside the subway station to reduce the speed of the suspect's escape; the helicopter ambulance transfer plan for seriously injured people will evacuate all seriously injured people at the scene.

[0094] 10. At T5, 20 public security police and 20 armed police arrived at the scene. The public security department implemented the [Emergency Evacuation] plan, assigned 10 public security police to assist in the evacuation of passengers and increase the speed of passenger evacuation; the public security department implemented the [Suspect Screening] plan, assigned 10 public security and 10 armed police to conduct suspect screening in relevant areas; the public security department implemented the [Alarm Area Blockade] plan, assigned 10 armed police to conduct alarm blockade in relevant areas, making the probability of suspects escaping zero and preventing the evolution of "other violent emergency events". 15 emergency personnel arrived at the scene, and the emergency department implemented the [On-site First Aid] plan, assigned 15 emergency personnel to perform on-site first aid and assigned 3 ambulances to send the injured to the emergency center. At the same time, the public security department implemented the [Traffic Escort] plan, assigned 10 traffic police and 10 police motorcycles to escort emergency vehicles to increase movement speed. 30 firefighters and 5 fire trucks arrived at the scene. The fire department and the emergency command center implemented the [on-site fire disposal] plan, assigning 30 firefighters, 5 fire trucks, 10 engineering rescue professionals, and 30 sets of rescue materials to carry out fire disposal at the subway station.

[0095] 11. At T6, the public security police and armed police successfully arrested three suspects, all passengers in the subway station were evacuated, all the injured were transferred to the emergency center, and the fire in the subway station was basically extinguished. The completion of the above means that the joint simulation of the emergency plan is completed, and each process of the simulation is recorded.

[0096] 12. The experts log into the assessment system, set the assessment focus and generate the assessment strategy profile, and score the deduction results in the performance assessment results.

[0097] The parameter calculation in the deduction system is shown as follows:

[0098] Danger factor = 3 (used to evaluate the current danger level of the event, which can be dynamically affected by multiple parameters. Low = 1, Medium = 2, High = 3)

[0099] Number of dangerous elements = 3

[0100] Emergency event evolution speed = 1

[0101] Road complexity = 10 (bottom = 10, middle = 30, high = 50)

[0102] Fire parameter = 0

[0103] Fire spread parameter = 0

[0104] Number of passengers in the station = 80

[0105] Mass evacuation speed = 0

[0106] Suspect's escape speed = 0

[0107] Total number of people at the incident site = 80

[0108] Initialization phase:

[0109]

[0110]

[0111] Fire parameter = risk factor × 10 = 30

[0112] Fire spread parameter = risk factor × 0.3 = 0.9

[0113] Mass evacuation speed = (100-fire parameter) ÷ 200 = 0.35

[0114] Suspect's escape speed = crowd evacuation speed × 0.065 = 0.02275

[0115] Real-time calculation stage:

[0116] Probability of death from severe injury = (0.01 × risk factor × injury duration) %

[0117] Escaped suspect = escape speed of the suspect × deduction time

[0118] Emergency event evolution progress = emergency event evolution speed × simulation duration + fire parameters If the emergency event evolution progress > 500, the event will evolve into a "subway station explosion":

[0119] Fire parameter = Fire parameter × (1 + Random (0.2, 0.5))

[0120] Execute the [Preliminary Fire Control] Plan:

[0121] Fire spread parameter = fire spread parameter - 0.1 × number of emergency fire extinguishing devices

[0122] Implementation of the [Traffic Control] Plan:

[0123] Within 1.5 km of subway station A, the road complexity = 0.

[0124] Execute the [Traffic Escort] Plan:

[0125]

[0126] When executing the [Injured Persons Treatment] plan, the real-time calculation of the probability of serious injury and death is changed to:

[0127] Probability of death from serious injury = (0.01 × (risk factor - 0.15 × number of first aid supplies invested) × duration of injury) % Execute [Evacuation of passengers], [Emergency evacuation], [On-site emergency response] plans: Evacuation speed of the masses = (100 - fire parameters) ÷ 200 + 0.15 × number of assigned police officers

[0128] +0.1×(number of assigned on-site management personnel + number of assigned on-site disposal personnel)

[0129] Number of passengers in the station = Number of passengers in the station - Evacuation speed × time step

[0130] Execute the [blockade of relevant areas on site], [on-site emergency response], and [blockade of warning areas] plans:

[0131]

[0132] Execute the emergency plan [Transfer of seriously injured patients by ambulance helicopter]:

[0133] Number of seriously injured passengers = 0

[0134] If the [Subway Suspension] plan is not implemented, every five minutes:

[0135] Number of passengers in the station = Number of passengers in the station + 30

[0136] Total number of people at the incident site = Total number of people at the incident site + 30

[0137] If the [blocking of relevant areas on site] plan is not implemented, every 15 seconds:

[0138] Number of passengers in the station = Number of passengers in the station + 1

[0139] Total number of people at the incident scene = Total number of people at the incident scene + 1

[0140] Execute the [On-site Emergency Response] Plan:

[0141]

[0142] When the number of seriously injured passengers is less than 0, the number of seriously injured passengers = 0

[0143] Number of lightly injured passengers = Number of assigned first aid personnel - Number of lightly injured passengers

[0144] When the number of slightly injured passengers is less than 0, the number of slightly injured passengers = 0

[0145] Execute the [On-site Fire Disposal] plan:

[0146] Fire spread parameter = Fire spread parameter - (number of assigned firefighters × 0.2 + number of assigned fire trucks)

[0147] × On-site firefighting time

[0148] When the fire spread parameter is less than 0, the fire spread parameter = 0.

[0149] Fire parameters = Fire parameters -

[0150] (Number of assigned firefighters × 2 + Number of assigned fire trucks × 2.5 + Number of engineering rescue professionals × 1.2 + Number of rescue materials × Time for on-site firefighting

[0151] When the fire intensity parameter is less than 0, the fire intensity parameter = 0.

[0152] Execute the [suspect screening] plan:

[0153]
