[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0022] Referring to Figures 1 to 4 The model for simulating the fire spread in a subway station shown in the drawings comprises a station building 1, an entrance and exit one 2 and an entrance and exit two 3 arranged at two sides of the station building 1 respectively, and the station building 1 is provided with a tunnel, a staircase, an escalator, a security gate and a two-way platform; the tunnel, the staircase, the escalator, the security gate, the two-way platform, the entrance and exit one 2 and the entrance and exit two 3 are all provided with fire simulation devices 5; the top of the station building 1 is a dome made of transparent acrylic panels, and the entrance and exit one 2 and the entrance and exit two 3 are both provided with platform panels.

[0023] The station building 1 is proportionally restored according to a subway station, mainly made of acrylic panels, and the internal wiring is also in accordance with the standard requirements for the construction of subway stations. The transparent setting is more conducive to the direct observation of the internal fire situation. The dome is connected by magnetic attraction and can be removed for cleaning. Of course, the fire simulation devices 5 are not limited to the above positions, and are arranged according to the places and environments where fires are prone to occur. In this way, the fire spread scene from the occurrence of a fire point to the spread of the fire can be more intuitively and accurately simulated.

[0024] Moreover, when one of the simulation nodes is started to simulate the occurrence of a fire, the smoke generated in the process spreads around it, and the nearby simulation nodes receive the smoke signal, which can be started. In this way, according to the direction of the smoke, the simulation nodes in the spread area can receive the signal and quickly form the state of fire spread.

[0025] The fire simulation device 5 is in communication connection with a simulation system, and the fire simulation device 5 comprises a plurality of simulation nodes, which are started to simulate a fire scene when one of them receives a smoke signal; the simulation node comprises a control system, which is in communication connection with a control switch, and the control switch is in communication connection with a smoke sensor, a photoelectric device, an atomizing system and a swinging fan.

[0026] When one of the simulation nodes is selected to simulate a fire, the control system can be a simple relay logic controller, or a complex programmable logic controller (PLC) or microcontroller (MCU). Taking the PLC as an example, it has a plurality of input ports for receiving sensor signals and output ports for controlling switches. When the PLC receives a signal from the smoke sensor, it will process it according to the pre-programmed logic. For example, when the smoke signal exceeds a certain threshold (such as a certain smoke concentration), the controller can determine that a fire has occurred, and then control the switch to act according to the set program. The control switch starts the smoke sensor, the photoelectric device, the atomizing system and the swinging fan;

[0027] The atomization system adopts an atomized liquid method, which is relatively safe and relatively clean in the process of generating smoke, and does not produce harmful chemical substances, compared with a chemical reaction smoke method and a solid combustion method.

[0028] The swing fan simulates the state of heat expansion after the fire occurs and the flow of the airflow generated smoke to the surrounding, which can improve the simulation speed, and of course, the swing fan can also be closed in the simulation system, and the swing fan can adjust the wind speed to simulate the size of the fire.

[0029] The above design has the advantages of more realistic restoration of the fire process, which can help firefighters to learn and practice, can simulate better rescue routes according to the internal scene when a fire occurs in one position, and can also adjust the fire parameters in the simulation of fire conditions to achieve the learning effect.

[0030] Moreover, the cost is lower and it can be reused, which is more realistic than computer modeling.

[0031] Each simulation node is provided with a fire extinguishing node, and the fire extinguishing node is used for fire extinguishing treatment of the simulation node.

[0032] The fire extinguishing node comprises a central control system, the control switch is in communication connection with the central control system, and the suction device is in communication connection with the control switch.

[0033] When the internal fire needs to be extinguished, the control system controls the control switch, the suction device sucks the smoke in the fire range, and the adjusting switch adjusts the resistance of the photoelectric device, so that the brightness of the photoelectric device gradually becomes dark, so that the fire extinguishing process can also be intuitively simulated.

[0034] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
