[0022] The present invention provides a fire warning system and method, which are respectively described below.

[0023] Figure 1 A schematic diagram of an embodiment of the fire warning system provided by the present invention and Figure 2 The system architecture diagram of an embodiment of the fire warning system provided by the present invention includes: Fire extinguisher 102 and detector 103; The controller 101 is mechanically connected to the fire extinguisher 102 and is communicatively connected to the detector 103, and is used to receive the fire area monitoring data sent by the detector 103, obtain the fire level of the fire area based on the fire area monitoring data, generate a fire extinguishing instruction based on the fire level, and start the fire extinguishing bottle corresponding to the fire level to spray and extinguish the fire based on the fire extinguishing instruction; The sound and light alarm 104 is connected to the controller 101 for sending out corresponding sound and light alarm signals based on the fire level. It can be understood that the fire warning system includes an integrated box, a fire extinguisher 102, a controller 101, a backup battery, a power management module, a relay, a power interface, a signal interface, a safety valve, a sprinkler interface, a flash buzzer, a power switch and a debugging switch; The power interface, signal interface, safety valve, sprinkler interface, flash buzzer, power switch and debugging switch are installed on the side of the integrated box. According to the usage scenario and the amount of fire extinguishing agent, the box can integrate various specifications of fire extinguishers 102 such as 2.4kg, 3kg, and 4kg. The signal interface leads to 24V, CAN communication, 485 communication, manual button, spray signal, fire alarm signal, fault signal, active input, active output, sound and light alarm and other interfaces from the inside of the box. The wiring can be selected according to actual needs, which enhances the universality and compatibility of the integrated fire protection system. A debugging switch is set on the box. When the debugging mode is turned on during testing and maintenance, it can prevent accidental startup and ensure the safety of personnel and equipment. The fire protection system is easy to install and suitable for a variety of scenarios. It can be widely used in industrial and commercial energy storage and new energy buses.

[0024] The fire warning system integrates the controller 101, fire extinguishing device and other components. The fire area only needs to leave an interface for fixing the box, which is convenient for installation. According to the usage scenario, the fire extinguisher 102 can also choose different specifications. The signal interface has reserved multiple interfaces such as sound and light alarm, manual button, active output, fire alarm signal, etc., which can be wired as needed to suit different demand scenarios. A debugging switch is set on the device. Turning on the debugging mode during testing and maintenance can prevent accidental startup and ensure the safety of personnel and equipment. It can be further understood that the integrated box adopts sheet metal and riveting technology, with a plate thickness of 1.5mm~2.0mm and a load-bearing capacity of about 30kg.

[0025] It can be further understood that the fire extinguisher 102 is connected and locked with the spray interface through a direct ferrule. Later, the fire extinguishing agent spray pipeline is connected through a quick-plug connector to transport the fire extinguishing agent to the fire area. The amount of fire extinguishing agent is calculated according to the usage scenario, and the box can integrate fire extinguishers 102 of various specifications such as 2.4kg, 3kg, and 4kg. The type of fire extinguishing agent can be non-pressure storage type or pressure storage type. It can be further understood that the controller 101 can communicate with the fire detection and fire area detector 103 and the central control, and can also issue commands after determining the fire situation to start the fire extinguisher 102 and transmit spraying, warning or fault signals. The controller 101 has fire classification warning and fire protection system fault detection functions.

[0026] It can be further understood that the power interface uses an aviation plug connector to ensure the stability of the system's power supply.

[0027] The signal interface is used to integrate the internal wiring of the system and then connect the peripheral equipment of the fire protection system, such as the detector 103, the sound and light alarm 104 and the manual button.

[0028] It should be further explained that in Figure 2The components in the integrated fire fighting box are in the middle blue box, including backup battery, power management module, power switch, controller 101, flash buzzer, debugging switch, and fire extinguisher 102. As the core device of the fire fighting system, controller 101 has multiple interfaces defined, and the required interface wiring can be selected according to the needs.

[0029] The power management module uses a step-up and step-down circuit to charge the backup battery. When the external power supply is connected, the backup battery is automatically charged and switched to the external power supply. When the external power supply is disconnected, it automatically switches to the backup battery to power the integrated fire protection system. This ensures that the backup battery is always fully charged.

[0030] The power switch is installed between the power supply and the controller 101, and is used to power on or off the power supply inside the fire protection system. When the power switch is pressed, the inside of the integrated fire protection box can work.

[0031] The debugging switch is used for functional verification in the R&D test, system joint debugging and testing, and maintenance phases, and can prevent the fire extinguisher 102 from being accidentally started. When the debugging switch is pressed, the system is in a testing state, and after the debugging switch is reset, it is in a normal working state.

[0032] The manual start button, the sound and light alarm 104 , the composite detector 103 and the like are peripheral devices, which are connected to the controller 101 via a Molex signal interface to ensure normal communication between the peripheral devices and the controller 101 .

[0033] Advantages of this solution: According to different project requirements, you can select the required interface connection reserved on the controller 101 to meet the needs of various scenarios and improve the universality of the integrated fire extinguishing system.

When the external power supply is disconnected, it automatically switches to the backup battery to power the integrated fire protection system. This can ensure that the backup battery is always fully charged. According to the 8h backup power requirement for fire protection and the power of peripheral equipment, the backup battery generally uses two 12V, 1.3ah~4.5ah batteries in series.

[0036] It can be further understood that the backup battery will continue to power the system for eight hours after the fire area loses power, ensuring that when a fire occurs, the integrated fire protection system can still operate normally after the power is cut off on site.

[0037] It can be further understood that the fire warning system includes an integrated box, a fire extinguisher 102, a controller 101, a backup battery, a power management module, a relay, a power interface, a signal interface, a safety valve, a sprinkler interface, a flash buzzer, a power switch, and a debugging switch; The power interface, signal interface, safety valve, sprinkler interface, flash buzzer, power switch and debugging switch are installed on the side of the integrated box.

When the debugging mode is turned on during testing and maintenance, it can prevent accidental startup and ensure the safety of personnel and equipment. The fire protection system is easy to install and suitable for a variety of scenarios. It can be widely used in industrial and commercial energy storage and new energy buses.

A debugging switch is set on the device. Turning on the debugging mode during testing and maintenance can prevent accidental startup and ensure the safety of personnel and equipment. In some embodiments of the present invention, the system further includes: a safety valve for releasing the pressure of the system.

[0042] It is understandable that the safety valve will automatically release pressure when the pressure in the integrated box is too high to prevent damage to the device or cause safety hazards. The safety valve pressure relief pressure is about 2.5MPa.

[0043] In some embodiments of the present invention, the system further includes: a power switch, electrically connected to the controller 101, configured to receive a power-on or power-off instruction sent by the controller 101, and to turn on or off an external power source based on the power-on or power-off instruction; The controller 101 is used to generate a power-on or power-off instruction and send the power-on or power-off instruction to the power switch.

[0044] It can be understood that the power switch is used to power on or off the internal power supply of the fire protection system.

[0045] It can be further understood that the integrated fire protection system box is directly installed in the reserved space, and then the power interface line, signal interface line and fire extinguishing agent spray pipeline that are prepared in advance are plugged in. Then install the peripheral equipment and wiring, and the integrated fire protection system is installed. After power on, press the power switch to detect whether there is any problem with the power on of the fire protection system; press the debug button to enter the debug mode, and debug with the peripheral equipment to simulate the fire alarm status and fault status, and determine whether the integrated fire protection system has no abnormalities based on the output signal. After the debugging is completed, reset the debug button, and the integrated fire protection system is in normal operation, monitoring the situation in the fire protection scene in real time.
