The difference between the daily training mode and the professional competition mode lies in the difference between the game difficulty and the score rule, the fire extinguishing shooting mode aims to train the skill of quickly aiming at the flame root injection, and the technical scheme is irrelevant to the technical scheme for realizing the embodiment of the application by a person skilled in the art, so that the specific rules of the game mode are not redundantly described in the specification.

Fig. 1 is a schematic flow chart of a method for simulating a fire drill according to an embodiment of the present disclosure, and referring to fig. 1, in the embodiment of the present disclosure, a method for simulating a fire drill is provided, including but not limited to steps S101, S102, S103, S104, S105, S106, S107, S108, S109, S110:

s101, generating an ignition point and a flame model corresponding to a target scene, wherein before starting the simulated fire drill, a drill worker needs to press a manual fire alarm button to simulate the fire alarm, and a fire alarm bell in a game is sounded, so that the simulated fire drill is started.

Optionally, before generating the fire point and the flame model corresponding to the target scene, a fire accident video may be selectively played, and the content of the fire accident video includes a fire alarm and personnel evacuation situation picture. The fire video is played before the game starts, so that the fire fighting atmosphere is created, and the training personnel can feel immersion and reality.

Before the simulated fire drill is started, the operator needs to press the manual fire alarm button to simulate the fire alarm, and the fire alarm bell in the game sounds, so that the simulated fire drill is started. Specifically, the fire fighting alarm device receives a starting signal which is triggered and input by manual operation of a fire fighting alarm button, plays the audio frequency of a fire alarm bell, and starts a fire extinguishing and extinguishing drilling program. The scheme of manually pressing the fire-fighting alarm button can train the training personnel to alarm and seek help consciousness through simulating the scene during the real fire, and simultaneously sends out alarm bell and sound, thereby increasing the sense of reality of simulating the fire-fighting drill scene. The manual fire-fighting alarm button comprises a virtual model or a simulation fire-fighting alarm button, the simulation fire-fighting alarm button consists of an alarm shell and a USB simulation keyboard function button, a fire-fighting rescue drilling program is controlled to be started, a player presses the manual fire-fighting alarm button to simulate fire-fighting alarm, and a drilling person is trained to recognize the fire-fighting alarm button through pressing, so that the player is familiar with the alarm operation steps; the system fire alarm ring is configured to simulate the fire alarm ring sound effect of the game system, and aims to improve the scene atmosphere and increase the sense of urgency.

And S102, responding to the first instruction, and determining the remaining life value of the ignition point.

In step S102, the life value of the ignition point is preset by the program, and a higher life value of the ignition point indicates that the flame is more difficult to extinguish, and the difficulty of simulating the fire drill is higher; the lower the life value of the fire point is, the easier the flame is to extinguish, and the lower the difficulty of simulating the fire drill is. Therefore, the manager can change the difficulty of simulating the fire drill by setting the initial value of the fire point.

It should be noted that step S102 specifically includes: receiving an input signal triggered by first input equipment, wherein the input signal comprises a cursor position coordinate of the first input equipment on a display window, judging whether a distance value between a virtual coordinate of the first input equipment and a virtual coordinate of an ignition point is within a preset range, and if so, reducing a life value of the ignition point at a preset rate; if not, the life value of the ignition point is kept unchanged. Wherein a diagram of a drill person interface applied when fighting a fire using the first input device is shown in fig. 6. The first input equipment comprises but is not limited to an electronic simulation fire extinguisher, the electronic simulation fire extinguisher mainly comprises a main controller MCU, a signal transmitting device, an entity key, an entity pressing handle and a sensor, the entity key is connected with the main controller MCU, and the sensor can sense spatial position information and transmit position data to a host system through the signal transmitting device. Specifically, when the drill personnel operate the electronic simulation fire extinguisher, the handle is pressed to push the valve core mandril of the head of the electronic simulation fire extinguisher to descend and switch on the electronic switch. Namely, the electronic simulation fire extinguisher is internally provided with a signal sensing and transmitting device, a switch control device, a pressure valve, a pressure handle, a machine head, a nozzle, a pressure indicator and a fire extinguishing agent tank which are integrally installed on the traditional fire extinguisher, and is formed by modifying the fire extinguisher; the selection of the fire extinguishing sequence means that the drilling personnel needs to judge the spreading speed according to the combustion flame model state in the game and preferentially extinguish the flame points with the highest spreading speed; adopt correct suppression measures and fire extinguisher to put out a fire according to burning flame model, burning flame model includes combustion medium and the fire type of corresponding A \ B \ C \ D, and correct suppression measures includes safety precaution and isolation measures, includes: when the burning medium is gas fire, the first step is to close a gas valve, similarly, when the burning medium is electrical equipment, an electrical switch is turned off first, and a player can simulate safe operation by activating an option button of a control cabinet in a game; the correct fire extinguisher means that the using range of the fire extinguisher held by a player in a game is suitable for extinguishing the current flame type, and the fire extinguisher is switched through a fire cabinet option button and a corresponding interface in a game scene; aim at the flame root and sweep and shoot until the fire source point extinguishes, aim at the flame root and include 2 processes: 1, pressing a pressing handle trigger key of the electronic fire extinguisher, and wirelessly transmitting a trigger signal to a host computer through a main control MCU (microprogrammed control unit) to enable the host computer to start to enter a corresponding virtual game picture; similar to an air mouse, the operation of the fire extinguisher is equivalent to the operation of the mouse in a coordinate space, the flame root is modeled, the orientation of the nozzle of the fire extinguisher can be mapped to be aligned with the flame root, and effective fire extinguishing can be realized only when the sight bead is aligned with the flame root. The host machine receives the cursor position coordinate of the electronic simulation fire extinguisher in the display window and then judges whether the distance value between the cursor position coordinate of the electronic simulation fire extinguisher in the display window and the virtual coordinate of the ignition point is in a preset range, if so, the life value of the ignition point is reduced at a preset rate; if not, the life value of the ignition point is kept unchanged. The process simulates the influence of the position of the fire extinguisher in a real fire-extinguishing scene on the fire-extinguishing effect, if the fire extinguisher is aligned to a fire point, the fire-extinguishing effect is a function of time, and correspondingly, the life value of the fire point in the embodiment is reduced; if the fire extinguisher is not aligned with the fire point, the fire cannot be extinguished, and the life value corresponding to the fire point in this embodiment will decrease with time. Meanwhile, when the drill personnel use the fire extinguisher, the volume of the solvent of the fire extinguisher is reduced, the dosage is reduced, and the time is positively correlated, namely the longer the time is, the less the residual solvent of the fire extinguisher is until the residual solvent is zero, and the fire extinguisher cannot be used. Through the electronic simulation fire extinguisher, the drill personnel can be familiar with the operation of the fire extinguisher, and meanwhile, the drill personnel can understand the fire extinguishing knowledge that the fire extinguisher needs to be aligned with a fire point when the fire is extinguished, so that the fire fighting awareness of the drill personnel is improved.

It is necessary to supplement that, the aforesaid electronic simulated fire extinguisher may be provided in plurality at the same time, that is, the first input instruction is triggered according to a plurality of first operations on a plurality of first input devices; the second input instruction is triggered according to a plurality of second operations on a plurality of second input devices. The personnel of performing a fire select the order of putting out a fire according to burning flame and state model to cooperation team member is put out a fire in coordination, and the order of putting out a fire of selection means that the personnel of performing a fire need be according to current fire source model and distribution characteristic, and the preliminary judgement is about to upgrade to the flame model of next stage and put out it, and team member is put out a fire its characterized in that in coordination, contains team cooperation combat scoring rule in the recreation scene settlement design: in the daily training mode, when a plurality of people put out a fire, the scores of the team are settled according to the number of fire sources put out in the initial stage and the spreading stage. The second drilling personnel, the third drilling personnel and the Nth drilling personnel can pick up and activate the electronic simulation fire extinguishers together, the system generates different combustion flame models and quantities according to the activated quantity of the fire extinguishers, the drilling personnel select correct fire extinguishers and extinguishing sequences according to the combustion object stacking models, combustion media, flame states and the like, and the fire extinguishers cooperate with the team members to extinguish initial fire at the highest speed. Through setting up a plurality of electronic simulation fire extinguishers simultaneously, realized that many people carry out the fire drill simultaneously, help training many people team's ability of putting out a fire.

In addition, when a plurality of persons drill, the system generates different combustion flame models and different combustion flame models according to the number of activated fire extinguishers, wherein the activation means that the system acquires state change information of the pointer to generate different combustion flame models and different combustion flame models.

Optionally, after determining the remaining life value of the fire point in response to the first instruction in step S102, the method further includes: displaying a fire alerting equipment comprising a personal protective ensemble and a fire extinguishing apparatus, wherein the combustibles are generated in the target scene, wherein selecting the fire alerting equipment begins calculating a first fire spread deadline; responding to an input selection signal, and obtaining the alarm equipment corresponding to the selection signal. . Specifically, before the drill personnel uses the electronic simulated fire extinguisher, different alerting equipment is displayed and the equipment selected by the drill personnel should include, but is not limited to, a personal protective suit. After the drill begins, the drill personnel need to click on the schematic diagram of the fire box and click and select from various fire-fighting equipment props in the box, if the drill personnel do not select or select necessary fire-fighting equipment, no fire-fighting equipment is available in the simulated fire-fighting drill process, on the contrary, when the drill personnel select the unnecessary fire-fighting equipment for fighting the initial fire, the alarm time is delayed, and further the actual fire-fighting time is delayed. Optionally, the necessary protective suit is selected, and if the fire fighter does not select the necessary protective suit, the life value of the fire fighter will be compromised during the simulated fire drill, resulting in fire fighting failure. S103, when the current time is the first fire spread deadline, detecting whether the remaining life value of the ignition point is 0.

In step S103, when the current time is the first fire spreading deadline, the system will perform value detection on all the fire points in the scene, if the life value of the fire point is zero, it indicates that the flame has been extinguished, and if the life value of the fire point is not zero, it indicates that the flame has not been completely extinguished, and there is a high possibility of spreading. It should be noted that the size of the flame pattern changes with the size of the fire point value, and the combustion flame pattern undergoes a decrease, a disappearance or an increase, the disappearance represents that the life value of the fire point is zero, i.e. the flame is extinguished. The flame spread cut-off time refers to a preset cut-off time of a certain time, and when the flame spread cut-off time is zero, the personnel for practicing needs to take further measures according to the current fire extinguishing condition. The flame spread cut-off time is used for simulating a real fire scene, and in a real fire disaster, flame can spread to other areas along with time, if the flame cannot be timely extinguished, the fire can spread, and greater casualties and property loss are caused.

And S104, if the remaining life value of the ignition point is 0, judging that the fire extinguishment is successful.

And S105, if the remaining life value of the ignition point is not 0, resetting the life value of the ignition point, and then executing the next step.

And when the current time is the first fire spread ending time, detecting that the life value of the fire point is not zero, namely when the current time is the first fire spread ending time and the fire point which is not extinguished still exists in the scene, entering a fire spread stage, reinitializing the life value of the fire point and starting the second time of fire spread ending time timing. After the second fire spread deadline is initiated, the number of fire points and flame patterns will be increased. The effect of increasing the number of ignition points and flame models is to simulate the scene of real fire spread and increase the difficulty of fire extinguishing.

It should be noted that the second input device includes, but is not limited to, an analog electronic fire-fighting lance. The simulated electronic fire-fighting lance consists of a perception feedback device and an electronic fire-fighting lance, the perception feedback device comprises an air compression and guide device, a joint and a fire-fighting hose, the air compression and guide device generates air flow, the hose is filled with the air flow flowing through the fire-fighting hose, and the effect of simulating the water flowing through the hose from a fire hydrant valve is achieved; the electronic fire-fighting lance is composed of a control switch, a mainboard and a lance shell, wherein a rotary switch handle triggers a mainboard button, and a main machine is provided with a trigger signal through the wireless transmission of a main control MCU (microprogrammed control unit), so that the fire hydrant extinguishing effect is simulated.

The effect of playing the fire scene escape drilling video, the scene escape passage view and the animation is that the key points of fire extinguishing are summarized through the video to the drilling personnel who fail to extinguish the fire, so that the drilling personnel can be helped to obtain the key field of fire extinguishing. The diagram of the drill personnel interface applied when determining a fire suppression failure is shown in fig. 7.

Fig. 2 is a schematic flow chart of a method for simulating a fire drill provided in the embodiment of the present application, and referring to fig. 2, in the embodiment of the present application, a method for simulating a fire drill is provided, which includes the following steps:

s201, randomly generating a target scene.

It should be noted that the target scene includes various scenes in which a fire may occur, and different combustibles are included in different target scenes, for example, the indoor space belongs to one of the scenes in which a fire may occur, and the corresponding combustibles include electric wires, natural gas, and the like. Different scenes and corresponding different combustibles are designed, and the training personnel can be helped to learn different processing methods corresponding to the different combustibles in the subsequent steps.

And S202, generating a fire point and flame model in the target scene according to the combustible substances.

S203, determining the life value of the ignition point and the first fire spread stopping time according to the preset value of the combustible and the distance value between the ignition point and the combustible.

In the foregoing embodiment, the life value of the fire point is preset by a program, and a higher life value of the fire point indicates that the flame is more difficult to extinguish, and the difficulty of simulating a fire drill is higher; the lower the life value of the fire point is, the easier the flame is to extinguish, and the lower the difficulty of simulating the fire drill is. Therefore, the manager can change the difficulty of simulating fire drill by setting the life value of the fire point. Optionally, the life value of the ignition point may also be calculated according to the preset value of the combustible and the distance value between the ignition point and the combustible, specifically: different combustibles have different preset values, for example, the combustibles A have the preset value A, calculation can be carried out according to the preset value A when an initialization value is calculated, the preset value of the combustibles A is preset by an administrator, for example, the combustibles (such as alcohol) which are difficult to extinguish are relatively larger than the preset value corresponding to the combustibles (such as paper) which are easy to extinguish, therefore, the preset value of the combustibles reflects the difficulty of extinguishing flames after the combustibles are on fire, and the scene of the fire is truly restored. In addition, the initial value for calculating the ignition point according to the distance value between the ignition point and the combustible is specifically as follows: acquiring virtual position coordinates of the ignition point and the combustible, calculating the distance between the two virtual position coordinates, namely acquiring the distance between the ignition point and the combustible, wherein the larger the distance between the ignition point and the combustible, the smaller the initial value of the ignition point is, and the smaller the distance between the ignition point and the combustible is, the larger the initial value of the ignition point is, so that different fire effects caused by different position distances between the combustible and the ignition point in the fire are truly reflected, and the real fire rescue situation is met.

Specifically, in step S203, calculating the first fire spread deadline according to the preset value of the combustible and the distance value between the ignition point and the combustible specifically includes: acquiring virtual position coordinates of the ignition point and the combustible, calculating the distance between the two virtual position coordinates, namely obtaining the distance between the ignition point and the combustible, and calculating the first fire spread stop time according to the preset value of the combustible and the distance value between the ignition point and the combustible, namely the larger the preset value of the combustible and the distance value between the ignition point and the combustible, the smaller the first fire spread stop time, the smaller the preset value of the combustible and the distance value between the ignition point and the combustible, and the larger the first fire spread stop time. This is because in a real fire the speed of fire propagation is related to the environment surrounding the fire point, in particular to whether there is combustible material near the fire point, which will be faster if there is combustible material near the fire point, and slower if there is no combustible material near the fire point or if the combustible material is further from the fire point. The fire spread stop time reflects the fire spread speed in the embodiment of the application, so that the first fire spread stop time is calculated according to the preset value of the combustible and the distance value between the ignition point and the combustible to be consistent with the actual situation of the fire scene.

And S204, determining the size of the flame model according to the life value of the ignition point.

And S205, responding to the first instruction, and determining the remaining life value of the ignition point.

And S206, when the current time is the first fire spread deadline, detecting whether the remaining life value of the ignition point is 0.

And S207, if the remaining life value of the ignition point is 0, judging that the fire extinguishment is successful.

And S208, if the remaining life value of the ignition point is not 0, resetting the life value of the ignition point, and then executing the next step.

And S209, responding to the second instruction, and determining the remaining life value of the ignition point.

And S210, when the current time is the second fire spread deadline, detecting whether the remaining life value of the ignition point is 0. .

And S211, if the remaining life value of the ignition point is 0, judging that the fire extinguishment is successful.

S212, if the remaining life value of the ignition point is not 0, judging that the fire extinguishment is failed.

As can be seen from the above description, in the embodiments of the present application, an ignition point and a flame model are generated, an input signal triggered by a first input device is received to calculate a life value of the ignition point, whether a first fire extinguishment is successful is determined by detecting whether the life value of the ignition point is zero, if not, a second fire spread deadline is started, an input signal triggered by a second input device is received to calculate the life value of the ignition point, and whether the fire extinguishment is successful is determined by detecting whether the life value of the ignition point is zero.
