The detection sensor is used to detect whether a fire occurs in the server cabinet in real time, and transmits a fire signal indicating that a fire has occurred to the controller in real time. When a fire occurs, the detection sensor sends a fire signal to the controller, and when there is no fire, the detection sensor does not send a signal. The detection sensors in this embodiment include: a temperature sensor, a smoke sensor and a flame sensor, which can simultaneously detect the fire information of a single server cabinet in terms of temperature, smoke and flame. Moreover, the temperature sensor, smoke sensor and flame sensor are respectively connected to the controller, and any fire signal will be transmitted to the controller, which can effectively improve the sensitivity of the detection sensor, thereby improving the fire safety of the server cabinet.

In this embodiment, the position and setting method of the detection sensor in the emergency server cabinet can be referred to FIG. 2 , which is a schematic structural diagram of the emergency server cabinet in a specific application scenario according to the embodiment of the present application. It can be seen from FIG. 2 that the detection sensor 3 is arranged in the middle of the top of the chassis 5 in the cabinet, and is arranged on the top of the cabinet, so that it can detect the temperature, smoke and flame information inside the entire server cabinet in an all-round and more accurate manner.

The fire protection assembly is used to seal off the server cabinet in the event of a fire inside the server cabinet. The fireproof assembly in this embodiment includes a motor and a fireproof curtain. The fireproof curtain is a roller shutter structure, which is arranged on the outer side of the cabinet, and is used to quickly close the entire server cabinet according to the control of the motor; In the event of a fire, the rapid deployment of the fire curtain is activated.

The fireproof curtain in this embodiment is a fireproof fireproof curtain made of refractory material, and the refractory material can be asbestos or the like. Refer to FIG. 2 for the arrangement of the fire curtain in the emergency server cabinet in this embodiment. It can be seen from Fig. 2 that the fire curtains 62 are distributed on the four outer sides of the cabinet 5 in the cabinet of the emergency server cabinet. When a fire occurs, since the controller 1 communicates with the motor 61, the motor 61 obtains After the signal is activated, the fire curtain 62 is driven to quickly unfold and fall to isolate the four sides of the cabinet body from the outside world, thereby preventing the fire from spreading. Under normal circumstances when there is no fire, the fire curtain is rolled up.

Continuing to refer to FIG. 1 , it can be seen that the emergency server cabinet in this embodiment is provided with a fire extinguishing assembly, which is used to extinguish fire when a fire occurs in the server cabinet.

Further, the fire extinguishing assembly includes: a solenoid valve 71 , an injector 73 and a fire extinguishing agent pressure storage tank 72 .

In this embodiment, the single-chip microcomputer and the peripheral circuit can adopt the single-chip microcomputer and the peripheral circuit in the prior art, which will not be repeated here.

Further, the emergency server cabinet of this embodiment is also provided with a 12V power supply, which is respectively connected to the fire prevention component, the fire extinguishing component, and the sound and light alarm through the controller, and the 12V power supply can use a battery. When no fire occurs, the 12V power supply is connected to the cabinet power supply through the controller to charge the 12V power supply; when a fire occurs, the 12V power supply supplies power to the detection sensor, fire prevention components, fire extinguishing components and sound and light alarm through the controller.

In this embodiment, the 12V power supply is used as a backup power supply. Under normal conditions, the cabinet power supply supplies power to the server cabinet and the controller, and the detection sensor, fire prevention components, fire extinguishing components, and sound and light alarms are powered by the controller; when a fire occurs, the cabinet power supply is cut off , The 12V power supply starts, supplies power to the controller, and supplies power to the detection sensor, fire prevention components, fire extinguishing components, and sound and light alarm through the controller.

Further, the server cabinet of this embodiment is also provided with a man-machine interface for inputting commands and reading information, and the man-machine interface is connected to the controller. Specifically, the man-machine interface includes a touch screen display. The user can input relevant commands through the touch screen of the display, and the touch screen display obtains relevant fire protection information through the controller, and feeds back the obtained relevant fire protection information to the display interface.

To sum up, in this embodiment, a detection sensor, a fire prevention component, a fire extinguishing component, an audible and visual alarm, and a controller are arranged in a single service cabinet to form a server cabinet fire protection system, which can operate independently, so that The fire emergency response of a single server cabinet is faster, which is conducive to improving the fire safety of the entire computer room. The emergency server cabinet can also report the fire information to the fire protection system in the computer room in time, which is convenient for the fire protection system in the computer room to determine which range of server cabinets to cut off the power according to the size of the fire, without having to cut off the power of the entire computer room, making the fire emergency treatment more targeted Responsibility, which can greatly reduce the probability of network interruption and data loss, and help reduce fire protection costs.
