In addition, traditional fire suppression systems may stop working when the main power supply fails, resulting in the inability to extinguish fires in a timely manner.
[0003] Therefore, it is necessary to develop a zoned precision gas fire suppression system for large spaces that can accurately extinguish fires in the affected area and is equipped with a backup power module to ensure that the system can still operate normally in the event of a power outage.

Detailed Implementation
[0021] The following detailed description, in conjunction with the accompanying drawings, illustrates the implementation of this utility model. However, these descriptions do not constitute a limitation of the present utility model and are merely illustrative. Furthermore, the advantages of this utility model will become clearer and easier to understand through this description.
[0022] Referring to the attached drawings: A zoned precision gas fire extinguishing system for large spaces is characterized by including a high-pressure steel cylinder 200 storing gaseous fire extinguishing agent and a fire controller 300 located outside the large space 100, wherein the large space 100 is divided into multiple small spaces 110.
[0023] The high-pressure cylinder 200 is equipped with a first control valve 410 at its opening. The first control valves 410 of multiple high-pressure cylinders 200 are connected in sequence to the second control valve 420 and nozzle 430 in the small space 110 through pipes 500. The second control valve 420 and nozzle 430 of each small space 110 are set independently and do not interfere with each other, ensuring accurate fire extinguishing.
[0024] The fire controller 300 is connected to the first control valve 410; the fire controller 300 is used to receive fire signals and control the opening of the first control valve 410 and the second control valve 420.
[0025] A detection device 610 is installed in the small space 110, and the fire controller 300 is connected to the detection device 610; the detection device 610 is used to detect fire signals.
[0026] A manual control device 620 is installed in the small space 110. The manual control device 620 is connected to the fire controller 300. The manual control device 620 is used to manually control the fire extinguishing system to extinguish the fire in the area when needed. The manual control device 620 is installed at the entrance of the small space 110 or in a conspicuous position.
[0027] The fire controller 300 is connected to the detection device 610 and the manual control device 620 in each small space 110 via the alarm device 630; the alarm device 630 is used to issue an audible and visual alarm signal when a fire occurs.
[0028] The detection device 610 includes a smoke detector 611 and a heat detector 612.
[0029] It also includes a backup power module 700, which is connected to the fire controller 300. The backup power module 700 is used to provide power support to the system when the main power fails, ensuring the normal operation of the system. The backup power module 700 includes one or more backup batteries, which are connected to the main power supply through a charging circuit. When the main power supply is working normally, the backup batteries are charged, and the power switching circuit automatically switches to backup battery power supply when the main power fails, ensuring uninterrupted system operation.
[0030] Each of the small spaces 110 is equipped with multiple nozzles 430 and detection devices 610; the multiple nozzles 430 ensure that the extinguishing agent can quickly and evenly cover the entire small space 110.
[0031] The gaseous fire extinguishing agent in the high-pressure steel cylinder 200 is perfluorohexanone.
[0032] The working principle of this utility model is as follows: Figure 2 As shown, this utility model includes two methods: automatic fire extinguishing and manual fire extinguishing.
[0033] Automatic fire extinguishing method: When a fire occurs, the smoke detector 611 and heat detector 612 in the small space where the fire occurs will send out fire alarm signals; after receiving the signal, the fire controller 300 will control the alarm device 630 to issue an audible and visual alarm, and at the same time issue a command to open the second control valve 420 of the nozzle 430 in the corresponding small space 110 and the first control valve 410 of the high-pressure steel cylinder 200. Perfluorohexanone gas extinguishing agent is quickly released into the small space 110 through the pipeline 500 and the nozzle 430 to achieve the purpose of precise fire extinguishing;
[0034] Manual fire extinguishing method: When a fire occurs, staff can directly activate the fire controller 300 through the manual control device 620 in the small space on fire. The fire controller 300 controls the alarm device 630 to issue an audible and visual alarm. At the same time, it opens the second control valve 420 of the nozzle 430 in the corresponding small space 110 and the first control valve 410 of the high-pressure cylinder 200. Perfluorohexanone gas extinguishing agent is quickly released into the small space 110 through the pipeline 500 and the nozzle 430 to achieve the purpose of precise fire extinguishing.
[0035] The backup power module 700 automatically switches to provide continuous power to the system in the event of a main power failure, ensuring that the firefighting process is not affected by power interruption.
[0036] This invention divides a large space 100 into multiple smaller spaces 110, each of which is independently equipped with a nozzle 430 and a detection device 610, thereby achieving precise fire extinguishing, improving fire extinguishing efficiency, reducing the waste of extinguishing agents and the impact on areas not yet on fire. It is applicable to various large spaces, such as shopping malls, warehouses, and exhibition halls.
[0037] Example
[0038] like Figure 1 As shown, the large space 100 is an exhibition hall, which is divided into multiple smaller spaces. Each smaller space is equipped with a nozzle 430 and a detection device 610. The high-pressure cylinder 200 and the fire controller 300 are installed outside the exhibition hall. The backup power module 700 is installed in the fire control room and connected to the main power supply to ensure that it can be switched to the backup power module 700 immediately when the mains power is interrupted.
[0039] All other unspecified parts belong to the prior art.
