Description

TECHNICAL FIELD

[0002] Fire has become one of the main disasters that seriously threaten human property and life safety, especially ship fire and building fire, and it is a difficult problem to quickly put out the fire, therefore, efficient fire extinguishing training means becomes an important way to improve the fire extinguishing speed. The current fire extinguishing training generally relies on a special training site to carry out fire fighting training through a real fire training system, but the site is relatively fixed and has high limitations, it is difficult to simulate the internal structure of various buildings or ships, the training effect will be greatly reduced after the training personnel are familiar with the training mode, and the training resources have high threshold, which is difficult to popularize and popularize. Especially for the commonly used water gun, improper operation method may cause the spread of fire, but due to the large water pressure, it is generally necessary to organize training in an open space, so it is difficult to carry out normal training.

[0003] At present, the existing fire fighting training simulation equipment mainly focuses on the simulation of fire, which can be roughly divided into two categories. One is to use a fan and other equipment to blow flexible materials such as cloth strips and keep them floating to simulate the burning effect of fire; the other is to use a light emitting device to simulate the dynamic effect of fire by light. The problems of the above two training simulation devices are that the devices are relatively independent and cannot be linked for fire extinguishing operation, and for different types of fire sources, such as oil fire, solid material fire, etc., the state of the fire cannot be changed with the degree of fire extinguishing operation specification when the fire fighting simulation fire extinguishing action is carried out.

[0104] As a preferred technical solution of the present application, the flame simulation linkage device 2 further comprises a USB interface 22, a full-featured data interface 23, a high-definition interface 24, and a magnetic back plate 25.

[0105] The USB interface 22 is connected with the central processing unit 7, and is used for maintaining, software upgrading and data exporting of the central processing unit 7.

[0106] The full-featured data interface 23 is connected with the central processing unit 7, and a plurality of groups of flame simulation linkage devices 2 can be connected in series by using a data line to simulate a flame spread scene. When the flame spreads to the left or right side of the liquid crystal display 5, the liquid crystal display 5 on the adjacent flame simulation linkage device 2 displays the spreading flame. The technical principle is to use the expansion screen display technology of the computer. When another device is connected, the new device is automatically recognized as a display. The flame simulation display image of the original device can be expanded to the new connected device, so that a larger area of fire can be displayed. This is convenient for the operator to simulate the fire according to the scene, and has the function of automatic recognition after connection.

[0107] The high-definition interface 24 is connected with the driving board 4, and is used for the function of outputting the flame state displayed by the liquid crystal display 5 to any external screen through a high-definition data line, which is convenient for the operator to observe the flame state.

[0108] The magnetic back plate is arranged at the rear end of the equipment shell 19. The magnetic back plate has magnetism and is provided with buckles. The magnetic back plate or the buckles thereon can be fixed on the surface of various objects, and waterproof design is simultaneously performed.

[0109] As a preferred embodiment of the present invention, the flame simulation linkage device 2 further includes a signal receiving module connected to the central processing unit 7 for receiving communication signals from an external remote control device. It also includes a remote control device for controlling the flame simulation linkage device 2, comprising a remote power button 27, a system start button 28, a training mode button 29, an assessment mode button 30, an oil fire type button 31, a solid fire type button 32, a signal transmitting module 33, and a battery 34. The remote power button 27 is used to remotely control the flame simulation linkage device 2 to open or close; the system start button 28 is used to remotely start the system; the training mode button 29 is used to remotely enter the training mode; the assessment mode button 30 is used to remotely enter the assessment mode; the oil fire type button 31 is used to select to simulate an oil fire; the solid fire type button 32 is used to select to simulate a solid fire; the signal transmitting module 33 is used to transmit signals to the signal receiving module of the flame simulation linkage device 2; and the battery 34 supplies power to the remote control device.

[0110] In this invention, the method for determining whether the illumination position of the light beam emitted by the light source simulation mechanism 3 of the fire-fighting simulated water gun 1 is an effective fire extinguishing position is as follows: if any photosensitive sensor 6 located at the base of the flame receives the light source signal, it is determined that the illumination position of the light beam emitted by the light source simulation mechanism 3 is effective. The calculation basis for the light intensity is the average light intensity detected by all photosensitive sensors 6 that receive light source information at the same time.

[0111] The flame simulation linkage device 2 has three functional modes: teaching mode, training mode, and assessment mode.

[0112] Teaching model.

[0113] The teaching mode consists of instructional videos that incorporate fire hoses into the fire simulation linkage device. The videos consist of two parts: one part shows how to use a regular fire hose, and the other part shows instructions for using a simulated fire hose.

[0114] Training mode.

[0115] In the training mode, the fire simulation linkage device can be placed in the cabin or building in advance during training, and can be started in advance or through remote control. After starting, the liquid crystal display screen 5 interface appears the type of fire to be simulated. After selecting the type, the interface starts to simulate the process of changing from initial fire to large fire. After receiving the fire extinguishing instruction, the trainees quickly connect the fire simulation water gun 1 and the water hose, enter the fire scene to find the fire source, and start to extinguish the fire. After the light sensor 6 of the fire simulation linkage device detects the light source information of the fire simulation water gun 1, the timing is started. At the same time, the central processor 7 cooperates with the light sensor 6 to collect the light beam intensity and light beam irradiation position of the fire simulation water gun 1, and records them. The simulated flame state gradually becomes smaller with the continuous extinguishing process until it is extinguished. After the training is completed, the screen displays green prompt and gives the information of fire extinguishing time, water gun opening angle, etc. as the reference of training effect.

[0116] Examination mode

[0117] In the examination mode, the fire simulation linkage system is placed in the cabin or building in advance during examination, and is started through remote control according to the examination instruction and set fire type. The interface starts to simulate the process of changing from initial fire to large fire. After receiving the fire extinguishing instruction, the trainees quickly connect the laser training fire water gun and the water hose, enter the fire scene to find the fire source, and start to extinguish the fire. After the fire simulation linkage system detects the laser training fire water gun irradiation, the timing is started. At the same time, the light beam intensity and light beam irradiation position of the fire simulation water gun 1 are collected and recorded. The simulated flame state gradually becomes smaller with the continuous extinguishing process until it is extinguished. After the training is completed, the screen displays green prompt and gives the information of fire extinguishing time and water gun opening angle, etc. At the same time, the examination result is given by using the built-in algorithm of the system.

[0118] In the above training mode and examination mode, when the fire source is oil fire, the liquid crystal display screen 5 displays that the fire source is oil fire, and the root of the oil fire is located at the lower bottom or upper top of the liquid crystal display screen 5. When the root of the fire is located at the lower bottom of the liquid crystal display screen, the judgment basis for judging whether the light beam irradiation position emitted by the light source simulation mechanism 3 on the fire simulation water gun 1 is effective is that the light sensor 6 on the lower side of the fire source on the liquid crystal display screen 5 receives the light source information, and the light radiation angle is 30° to 45°, and the light intensity should be higher than the ambient light 100LX. For general indoor ambient light, the illuminance is about 100Lx to 600Lx. In order to avoid the influence of indoor ambient light, the examination index should be set according to the actual measurement of indoor light intensity during training.

[0119] When the fire source is solid, the liquid crystal display 5 displays that the fire source is solid fire, and the fire source root of oil fire is located at the central position of the lower bottom or the upper top of the liquid crystal display 5. When the fire source root is located at the lower bottom of the liquid crystal display, the judgment basis for judging whether the light beam irradiation position of the light source simulation mechanism 3 of the fire-fighting simulation water gun 1 is effective is that the light sensitive sensor 6 located below the fire source on the liquid crystal display 5 receives the light source information, and the light irradiation angle is 30° or less, and the light irradiation intensity is higher than the ambient light 100LX. For the general indoor ambient light, the light intensity is about 100Lx to 600Lx. In order to avoid the influence of the indoor ambient light, the examination index should be set according to the actual measurement of the indoor light intensity during training.

[0120] In the above embodiment, the default distance between the trained personnel and the fire source is 100cm, and the trained personnel faces the fire source. The light irradiation angle α is calculated according to the following formula:

[0121]

[0122] In the above formula, A represents the number of light sensitive sensors that receive light source information at the same time, and X is the distance between two adjacent light sensors.

[0123] The calculation basis of the light intensity is that the light intensity is the average value of the light intensities detected by all light sensitive sensors 6 that receive light source information at the same time.

[0124] In order to further improve the authenticity of training or examination, the effective light intensity received by the light sensitive sensor 6 can be set for different types of fire sources. The light intensity of the fire-fighting simulation water gun 1 under the condition of solid fire source should be higher than that under the condition of oil fire source. For example, under the condition of oil fire source, the light of the fire-fighting simulation water gun 1 is divergent and radiates, simulating water spray, and when the light intensity is greater than the indoor light intensity 100LX, it is determined that the light intensity meets the standard, and when it is lower than 100LX, it is determined that the light intensity does not meet the standard. Under the condition of solid fire source, the light of the fire-fighting simulation water gun 1 is concentrated and radiates, simulating water column spray, and when the light intensity is greater than the indoor light intensity 200LX, it is determined that the light intensity meets the standard, and when it is lower than 200LX, it is determined that the light intensity does not meet the standard.

[0125] As a preferred technical solution of the present application, the flame simulation linkage device 2 also detects the scanning frequency of the light beam emitted by the light source simulation mechanism 3 of the fire-fighting simulation water gun 1.

[0126] The calculation basis of the scanning frequency is that, for example, when the fire source root is located at the lower bottom of the liquid crystal display 5, and the central processing unit 7 drives only the light sensitive sensor 6 located at the lower side of the liquid crystal display 5 to work,

[0127] The central processor 7 starts timing according to the first complete light source signal detected by the light sensor working at the leftmost or rightmost side, stops timing according to the last complete light source signal detected by the light sensor working at the leftmost and rightmost side, and calculates the time t; the central processor 7 is based on the total number n of times that the light source signal is received by the light sensor working at the leftmost or rightmost side; and the scanning frequency f is:

[0128]

[0129] In the above formula, n is the total number of times that the light source signal is received by the light sensor working at the leftmost or rightmost side, and t is the time used from the first detection of a complete light source signal by the light sensor working at the leftmost or rightmost side to the last detection of a complete light source signal.

[0130] The application also provides a fire simulation fire fighting training method based on a fire simulation linkage fire fighting system, comprising the following steps:

[0131] First step: the power switch 20 of the fire simulation linkage fire fighting system sets the fire source type by touching the liquid crystal display screen 5, the central processor 7 transmits the fire source information to the liquid crystal display screen 5 through the driving board 4, the liquid crystal display screen 5 displays a fire picture caused by a certain type of fire source, and the position of the fire source root is located at the edge position of the liquid crystal display screen 5, and the central processor 7 drives the light sensor 6 working at the position of the fire source root on the liquid crystal display screen 5;

[0132] Second step: the trainee holds the fire simulation water gun 1, pulls the hand-pulled switch 9, and the lithium battery 11 supplies power to the light source emitting lamp, and the light source emitting lamp starts to illuminate;

[0133] Third step: the trainee adjusts the illumination radiation angle by setting the focusing combination lens of the fire simulation water gun 1 according to the fire source type;

[0134] Fourth step: the trainee aims the illumination of the fire simulation water gun 1 at the light-transmitting opening 21 close to the fire source root position of the liquid crystal display screen 5 on the fire simulation linkage fire fighting system, and the light sensor 6 collects and transmits the light source information and illumination intensity information to the central processor 7;

[0135] Fifth step: the central processor 7 determines the effective fire extinguishing position based on the fire source type displayed by the fire source simulation mechanism,

[0136] According to the position of the signal receiver receiving the light source information emitted by the light source simulation mechanism 3, the irradiation position of the light beam emitted by the light source simulation mechanism 3 is obtained, and it is judged whether the light beam irradiation position is an effective fire extinguishing position;

[0137] According to the light source information of the light beam emitted by the light source simulation mechanism 3 received by the signal receiver, the light intensity information is judged whether the light intensity is up to standard;

[0138] When the light beam irradiation position is valid and the light intensity is up to standard, the central processing unit 7 determines that the fire is effectively extinguished, and the central processing unit 7 transmits signals to the liquid crystal display 5 through the driving board 4, so that the simulated flame becomes smaller and gradually extinguishes.

[0139] When the light beam irradiation position is invalid or the light intensity is not up to standard, the central processing unit 7 determines that the fire is not effectively extinguished, and the central processing unit 7 transmits signals to the liquid crystal display 5 through the driving board 4, so that the simulated flame becomes larger.

[0140] The above is only a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the disclosed technical scope, which should be covered by the protection scope of the present application.
