[0072] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0073] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0074] To achieve the above-mentioned objectives, the present disclosure provides a gas fire extinguishing method, which is applied to a gas fire extinguisher, wherein the sensing element mounting assembly of the gas fire extinguisher is mounted on a mounting plate in a horizontally rotatable manner, the sensing element mounting assembly is provided with a sensing element, and the sensing element faces different directions as the sensing element mounting assembly rotates, and the main body of the gas fire extinguisher is provided with a plurality of nozzles, and the plurality of nozzles are rotatably arranged in the horizontal and vertical directions. Figure 1 FIG1 is a flow chart showing a method for extinguishing a fire with a gas fire extinguisher according to an embodiment, the method comprising:

[0075] S11. Determine the rotation angle of each rotation and the pause duration of each pause when the sensing element mounting assembly of the gas fire extinguisher intermittently rotates horizontally on the mounting plate according to the preset number of intermittent points and the single-circle rotation duration.

[0076] In the embodiment of the present disclosure, the number of intermittent points can be determined based on the layout of the gas fire extinguisher. For example, in a database center such as a computer room, the places where fires are usually prone to occur are the power supply and cabinets of the servers, while the probability of fires occurring in pipelines and other areas where servers are not placed is lower. Therefore, the number of intermittent points can be determined based on the number of servers and the number of server power supplies within the fire extinguishing range of the gas fire extinguisher.

[0077] In one embodiment, the intermittent point position of the gas fire extinguisher can also be set, and then the rotation angle of each rotation and the pause duration of each pause of the sensing element mounting assembly of the gas fire extinguisher when intermittently rotating in the horizontal direction on the mounting plate can be determined according to the maximum rotation speed of the gas fire extinguisher, the number of intermittent points and the single-circle rotation duration. For example, according to the adjacent intermittent point positions, the rotation angle of each rotation is determined, and the sensing element mounting assembly of the gas fire extinguisher is rotated at the maximum rotation speed. The time taken to rotate 360 ​​degrees can be calculated, and then each intermittent point position is paused for the same length of time. The time taken to rotate 360 ​​degrees is subtracted from the single-circle rotation duration to obtain the total pause duration, and the total pause duration is divided by the number of intermittent points to obtain the pause duration of each pause.

[0078] S12. Control the sensing element mounting assembly of the gas fire extinguisher to intermittently rotate in the horizontal direction on the mounting plate according to the rotation angle and the pause duration, and sense whether there is a fire within the fire extinguishing range through the sensing element.

[0079] It can be understood that in the embodiment of the present disclosure, the sensing element mounting assembly can be arranged with a motor, and then the sensing element mounting assembly can be driven by the motor to intermittently rotate in the horizontal direction on the mounting plate according to the rotation angle and the pause time.

[0080] The sensing element may include at least one of infrared, ultraviolet, camera, smoke sensor, and temperature sensor.

[0081] S13. When a fire is sensed to exist within the fire extinguishing range, the direction of the fire is determined, and the sensing element mounting assembly of the gas fire extinguisher is controlled to stop intermittent rotation, while the plurality of nozzles are controlled to turn horizontally toward the direction of the fire.

[0082] When the sensor assembly determines that a fire exists within the extinguishing range, the current orientation of the sensor assembly is determined to be the fire's location. If the sensor assembly is rotating, it immediately stops; if it is resting, it remains in its resting position. Simultaneously, the current orientation of all nozzles is determined. If the orientation of the sensor assembly's sensor assembly is inconsistent with the orientation of the nozzles, the nozzles are controlled to horizontally align with the orientation of the sensor assembly, thereby controlling the multiple nozzles to horizontally align with the fire's location.

[0083] S14. When the nozzle is turned horizontally toward the direction of the fire, the nozzle is controlled to rotate back and forth in the vertical direction to spray inert gas for fire extinguishing, and the sensing element mounting assembly of the gas fire extinguisher is controlled to rotate at a first rotation speed within a preset angle range of the direction of the fire and at a second rotation speed within a non-preset angle range of the direction of the fire to monitor whether there is a fire within the non-preset angle range, wherein the first rotation speed is greater than the second rotation speed.

[0084] In the embodiment of the present disclosure, each nozzle has a preset vertical rotation angle and vertical rotation speed, so that when the nozzle is turned horizontally toward the direction of the fire, the nozzle is controlled to rotate back and forth in the vertical direction according to the vertical rotation angle and vertical rotation speed to spray inert gas for fire extinguishing.

[0085] In the present disclosure, the preset angle range can be 15° to the left and right. A 30° range of 15° to the left and right of the fire location can be determined as the preset angle range, and the other 330° can be determined as the non-preset angle range.

[0086] The first rotation speed is greater than the second rotation speed, so that the presence of a fire can be quickly detected within a preset angle range, while the rotation can be relatively slow within a non-preset angle range, so that the presence of a fire can be accurately detected.

[0087] The above technical solution determines the rotation angle of each rotation and the pause duration of each pause when the sensing element mounting assembly of the gas fire extinguisher intermittently rotates in the horizontal direction on the mounting plate according to the preset number of intermittent points and the single-circle rotation duration; controls the sensing element mounting assembly of the gas fire extinguisher to intermittently rotate in the horizontal direction on the mounting plate according to the rotation angle and the pause duration, and senses whether there is a fire within the fire extinguishing range through the sensing element; and can dynamically monitor whether there is a fire within the fire extinguishing range to avoid blind spots in fixed monitoring.

[0088] Furthermore, when a fire is sensed to exist within the fire extinguishing range, the direction of the fire is determined, and the sensing element mounting assembly of the gas fire extinguisher is controlled to stop intermittent rotation, while the plurality of nozzles are controlled to turn horizontally toward the direction of the fire; when the nozzles turn horizontally toward the direction of the fire, the nozzles are controlled to rotate back and forth vertically to spray inert gas for fire extinguishing, and fire extinguishing is only performed on the direction of the fire, rather than spraying inert gas in all directions at the same time. This not only improves the accuracy of fire extinguishing, but also avoids wasting inert gas, thereby improving the efficiency of fire extinguishing.

[0089] Furthermore, the sensor mounting assembly of the gas fire extinguisher is controlled to rotate at a first rotational speed within a preset angular range of the fire location and at a second rotational speed within a non-preset angular range of the fire location, so as to monitor whether a fire exists within the non-preset angular range, wherein the first rotational speed is greater than the second rotational speed. This allows for continuous monitoring of fires in other locations, thereby preventing fires from occurring in other locations from being effectively extinguished.

[0090] In a preferred embodiment, see Figure 2 As shown, S11, determining the rotation angle of each rotation and the pause duration of each pause when the sensing element mounting assembly of the gas fire extinguisher intermittently rotates in the horizontal direction on the mounting plate based on the preset number of intermittent points and the single-turn rotation duration, includes:

[0091] S111, obtaining a maximum rotational speed of the sensing element mounting assembly of the gas fire extinguisher rotating in a horizontal direction on the mounting plate;

[0092] The maximum rotation speed is determined by the mechanical structure of the sensor mounting assembly and the mounting plate.

[0093] S112. Divide the 360-degree rotation range of the sensor element mounting assembly of the gas fire extinguisher into equal angles according to the preset number of intermittent points to obtain the rotation angle of each rotation during the intermittent rotation.

[0094] It is understood that the angle is evenly divided, meaning that the rotation angle of each rotation is the same. For example, if the number of intermittent points is 12, the rotation angle of each rotation is 30°.

[0095] S113 , determining the pause duration of each pause according to the maximum rotation speed, the single-circle rotation duration, and a preset multiple relationship between the rotation duration of each rotation and the pause duration of each pause.

[0096] In the embodiment of the present disclosure, the preset multiple relationship between the rotation duration of each rotation and the rest duration of each rest is K=NX, where K is the rest duration, X is the rotation duration, K is the multiple, and K is a positive integer.

[0097] The above technical solution can determine the rotation angle of each rotation and the pause duration of each pause during intermittent rotation based on the maximum rotation speed, the number of intermittent points and the preset multiple relationship between the rotation duration of each rotation and the pause duration of each pause. It can monitor the existence of fire in the fire extinguishing range in all directions, thereby improving the accuracy of fire extinguishing.

[0098] In a preferred embodiment, the duration of each rotation is equal to the duration of each pause. In other words, the preset multiple relationship between the duration of each rotation and the duration of each pause is 1.

[0099] In a preferred embodiment, see Figure 3 As shown, before controlling the sensing element mounting assembly of the gas fire extinguisher to intermittently rotate in the horizontal direction on the mounting plate according to the rotation angle and the pause time, the method includes:

[0100] S100: Determine, through the Internet of Things, whether there is a user carrying a mobile terminal within the fire extinguishing range of the gas fire extinguisher.

[0101] S101. Determine, through the Internet of Things, that no user carrying a mobile terminal exists within the extinguishing range of the gas fire extinguisher.

[0102] In the embodiment of the present disclosure, the Internet of Things can be established via WiFi or Bluetooth. The mobile terminal can report its own GPS, so that it can be determined whether there is a user carrying the mobile terminal within the fire extinguishing range of the gas fire extinguisher based on the received GPS of the mobile terminal.

[0105] The terminal position of the mobile terminal relative to the gas fire extinguisher may be determined based on the received GPS of the mobile terminal.

[0106] S103: Determine the intermittent rotation range of the gas fire extinguisher according to the terminal orientation and the preset angle.

[0107] Among them, the preset angle can be 30° left and right, and the 60° range except the 30° left and right of the terminal orientation can be determined as the intermittent rotation range, and the 60° range except the 30° left and right of the terminal orientation can be determined as the non-stop angle range or non-monitoring angle range mentioned later.

[0108] S104: Control the sensing element mounting assembly of the gas fire extinguisher to intermittently rotate within the intermittent rotation range, and sense whether there is a fire within the fire extinguishing range through the sensing element.

[0109] In a preferred embodiment, S103, determining the intermittent rotation range of the gas fire extinguisher according to the terminal orientation and the preset angle, includes:

[0110] The intermittent rotation range and the non-stop angle range of the sensing element mounting assembly of the gas fire extinguisher are determined according to the terminal orientation and the preset angle.

[0117] In the embodiment of the present disclosure, the sensing element mounting assembly of the gas fire extinguisher does not pass through the non-monitoring angle range during the rotation process. The sensing element mounting assembly of the gas fire extinguisher rotates to the intersection with the non-monitoring angle range within the intermittent range, and the rotation direction of the sensing element mounting assembly of the gas fire extinguisher is reversed and rotated back in the direction it came from, thereby realizing the back and forth rotation of the sensing element mounting assembly of the gas fire extinguisher within the intermittent range.
