Description

Technical Field

[0001] The present invention is a fire spraying system based on Internet of Things (IoT) control and its implementation method, specifically relating to a fire spraying system that is controlled by the IoT, can automatically capture the ignition point indoors, and automatically adjust the angle for fire extinguishing, belonging to the technical field of fire spraying. Background Art

[0002] The Internet of Things connects all items through information sensing devices such as radio frequency identification to the Internet to achieve intelligent identification and management. The Internet of Things is integrated with intelligent perception, identification technology, pervasive computing, and ubiquitous network applications, and is known as the third wave of the development of the world information industry after the computer era and the Internet.

[0003] In the existing fire protection systems, the sprinkler valve only starts to spray liquid for fire extinguishing after sensing signals such as smoke and fire. By then, the fire has spread to a certain scale, causing certain damage to property and personnel. In places where relatively expensive items are stored, the losses can cause some irreversible harm, such as museums. Moreover, the existing sprinkler valves cannot sense the location and size of the fire ignition, but only spray in all directions without focus. Given a certain pipeline spraying pressure and flow rate, they cannot concentrate the spray on the fire source in the initial stage of the fire, and the effect in fire fighting is not good. For this reason, those skilled in the art have proposed a fire spraying system based on IoT control to solve the problems raised in the above background art. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a fire spraying system based on IoT control and its implementation method in view of the above deficiencies. The present invention monitors the temperature of objects in this area through an infrared camera and feeds back the coordinates of objects with abnormal temperatures to the control system. The control system starts the spraying system through the wireless network and can accurately locate and spray according to the location of the fire. The control system also transmits the fire situation to the local fire personnel and the local fire control system through network communication to make a quick response to the fire situation, improving the efficiency of fire fighting.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A fire spraying system based on IoT control includes a spraying mechanism, a shut-off mechanism, and a control system;

[0007] The spraying mechanism is used to automatically capture the ignition point and the size of the fire in the area, automatically adjust the position and angle of the sprinkler valve, and spray liquid at the ignition position;

[0008] The shut-off mechanism is used to automatically cut off the local power supply when a fire occurs;

[0009] The control system includes the detected operating data signals and the sent execution instructions to achieve the automatic operation of the spraying mechanism and the shut-off mechanism.

[0010] The spraying mechanism includes a spray valve. The spray valve is connected to a fire pipeline through a spray pipe. A pressure gauge is provided on the fire pipeline. The pressure gauge is used to detect the pressure of the circulating liquid in the fire pipeline. The spray pipe is a flexible pipe that can be twisted into a certain shape and angle. A No. 1 gear is provided between the spray pipe and the fire pipeline. The No. 1 gear meshes with a No. 2 gear through a gear structure. An angle sensor is connected above the No. 2 gear.

[0011] The spraying mechanism further includes an infrared camera. The infrared camera is installed on the lower surface of the indoor ceiling, on one side of the spray valve. The infrared camera is used to sense the temperature of the objects in the monitored area indoors and transmit the positions of the objects with abnormal temperatures to the control system to accurately provide the fire source coordinates for the spray valve.

[0012] Furthermore, a positioning hole is provided on the No. 1 gear. There are several positioning holes and they are distributed in a circular pattern. The positioning holes are through holes that penetrate the inside of the No. 1 gear. A positioning component is also connected above the No. 1 gear. The positioning component includes a cylinder. The cylinder is hollow. A positioning disk is embedded in the cylinder. A positioning column is connected below the positioning disk. The diameter of the positioning column is the same as the diameter of the positioning hole.

[0013] Furthermore, an electromagnet is provided above the cylinder. After the electromagnet is powered on, it can absorb the positioning disk and retract the positioning column into the cylinder. The spray valve opens and rotates in a certain direction. The spray valve drives the No. 1 gear to rotate, thereby driving the No. 2 gear to rotate. When the angle sensor detects that the spray valve has rotated in place, the electromagnet is powered off, and the positioning column is released and falls into the positioning hole, so as to be able to control the rotation angle of the spray valve.

[0014] Furthermore, a rotating component is connected below the No. 1 gear. The rotating component includes a wrapping layer. The wrapping layer surrounds the outer surface of the spray pipe. A stepping motor is also connected to the outer surface of the wrapping layer. When the No. 1 gear rotates, the rotating component also rotates together. When the No. 1 gear rotates in place, the stepping motor starts to twist the spray pipe and the spray valve to the fire source direction for accurate spraying.

[0015] When the infrared camera detects that the temperature of the objects in this area is abnormal, the infrared camera transmits the coordinates of the area with abnormal temperature to the control system. The control system starts the spray valve, the electromagnet is powered on, and then the No. 1 gear rotates. When the angle of the No. 1 gear rotates to the position with abnormal temperature, the electromagnet is powered off, the positioning column falls into the positioning hole, the No. 1 gear stops rotating, and the stepping motor starts to rotate the spray valve to the area with abnormal temperature for spraying liquid.

[0016] Further, the shutdown mechanism includes a circuit breaker installed at the main power inlet of the monitored site. A current measurement structure is provided at the outlet of the circuit breaker, which is used to detect the total current of the electricity consumption in this site and the temperature of the cable. An automatic tripping structure is also provided inside the circuit breaker. When the infrared camera or the current measurement structure monitors that the temperature of the cable in this site area is abnormal, the automatic tripping structure automatically shuts off the power supply in the local site.

[0017] Further, the control system includes a central controller, which is communicatively connected to the local control room. The local control room is connected to the local fire control system through the Internet. The central controller is used to receive the data detected by the spraying mechanism and the shutdown mechanism, and send operation instructions to the spraying mechanism and the shutdown mechanism. The central controller also sends the location of the fire to the local control room through communication, and the local control room also sends the fire situation in this area to the local fire control system at the same time.

[0018] Further, the central controller is also communicatively connected to a central wireless data processing center. The central wireless data processing center is wirelessly communicatively connected to an A local area network wireless transmitting and receiving module and a B local area network wireless transmitting and receiving module. The A local area network wireless transmitting and receiving module is used to detect the operation data of the spraying mechanism and also receive the spraying mechanism operation instructions sent by the central controller to realize the automatic operation of the spraying mechanism. The B local area network wireless transmitting and receiving module is used to detect the operation data of the shutdown mechanism and also receive the shutdown mechanism operation instructions sent by the central controller to realize the automatic operation of the shutdown mechanism.

[0022] Step S103, the infrared camera monitors whether the temperature of the objects in this area is abnormal; if so, step S104 is executed; if not, step S101 is executed;

[0023] Step S104, the infrared camera transmits the coordinates of the abnormal temperature area to the control system through the wireless network; after completion, step S105 is executed;

[0024] Step S105, the control system starts the electromagnet through the wireless network; after completion, step S106 is executed;

The central controller will start the spraying system to spray liquid on the fire location for fire extinguishing. The central controller is also connected to the fire control system through the Internet, and will also reflect the fire location and scale to the fire control center in the first time, greatly shortening the reaction time of people to the fire.

[0044] A fire - fighting spraying system based on Internet of Things control includes a spraying mechanism, a shut - off mechanism and a control system;

[0045] The spraying mechanism is used to automatically detect the fire ignition point and the size of the fire in the area, automatically adjust the position and angle of the spray valve, and spray liquid on the fire location;

[0046] The shut - off mechanism is used to automatically cut off the local power supply when a fire breaks out;

[0047] The control system includes the detected operation data signals and the sent execution instructions to realize the automatic operation of the spraying mechanism and the shut - off mechanism;

[0048] Such as Figures 1 to 4As shown, the spraying mechanism includes a spraying valve 5. The spraying valve 5 is connected to a fire pipeline 1 through a spraying pipe 21. A pressure gauge 15 is provided on the fire pipeline 1, and the pressure gauge 15 is used to detect the pressure of the circulating liquid in the fire pipeline 1. The spraying pipe 21 is a flexible pipe and can be twisted into a certain shape and angle. A No. 1 gear 6 is provided between the spraying pipe 21 and the fire pipeline 1. The No. 1 gear 6 is meshed with a No. 2 gear 7 through a gear structure. An angle sensor 8 is connected above the No. 2 gear 7.

[0049] A positioning hole 9 is provided on the No. 1 gear 6. There are several positioning holes 9 and they are distributed in a circular pattern. The positioning hole 9 is a through hole and penetrates through the inside of the No. 1 gear 6. A positioning component 4 is also connected above the No. 1 gear 6. The positioning component 4 includes a cylinder 11. The cylinder 11 is hollow. A positioning disk 13 is embedded in the cylinder 11. A positioning column 12 is connected below the positioning disk 13. The diameter of the positioning column 12 is the same as the diameter of the positioning hole 9.

[0050] An electromagnet 14 is also provided above the cylinder 11. After the electromagnet 14 is powered on, it can attract the positioning disk 13 and retract the positioning column 12 into the cylinder 11. The spraying valve 5 is opened. Due to the centrifugal force and reaction force of the liquid flow, the spraying valve 5 will rotate in a certain direction. The spraying valve 5 drives the No. 1 gear 6 to rotate, thereby driving the No. 2 gear 7 to rotate. When the angle sensor 8 detects that the spraying valve 5 has rotated in place, the electromagnet 14 is powered off, and the positioning column 12 is released and falls into the positioning hole 9, so that the rotation angle of the spraying valve 5 can be controlled.

[0051] A rotating component 18 is also connected below the No. 1 gear 6. The rotating component 18 includes a wrapping layer 20. The wrapping layer 20 surrounds the outer surface of the spraying pipe 21. A stepping motor 19 is also connected to the outer surface of the wrapping layer 20. When the No. 1 gear 6 rotates, the rotating component 18 also rotates together. When the No. 1 gear 6 rotates in place, the stepping motor 19 is started to twist the spraying pipe 21 and the spraying valve 5 in the direction of the fire source for precise spraying.

[0052] The spraying mechanism further includes an infrared camera 3, which is installed on the lower surface of the indoor ceiling, on one side of the spray valve 5. The infrared camera 3 is used to sense the temperature of objects in the monitored area indoors, and can calculate the positions of the objects in the area, and transmit the positions of the objects with abnormal temperatures to the control system, so as to accurately provide the fire source coordinates for the spray valve 5. When the infrared camera 3 detects that the temperature of the objects in this area is abnormal, the infrared camera 3 transmits the coordinates of the area with abnormal temperature to the control system. The control system starts the spray valve 5, the electromagnet 14 is energized, and then the 1# gear 6 rotates. When the angle of the 1# gear 6 rotates to the position with abnormal temperature, the electromagnet 14 is de-energized, and the positioning post 12 falls into the positioning hole 9, and the 1# gear 6 stops rotating. The stepping motor 19 is started, and the spray valve 5 is rotated to the area with abnormal temperature to spray liquid, so as to extinguish the initial fire in time.

[0053] As Figure 5 shown, the shutdown mechanism includes a circuit breaker 22, which is installed at the main incoming line of the power supply of the monitored place. The incoming line of the circuit breaker 22 is connected to the main incoming R line, S line, T line and N line of the monitored place. An electric current measuring structure 17 is provided at the outgoing line of the circuit breaker 22. The electric current measuring structure 17 is used to detect the total electric current of the electricity consumption of this place and the temperature of the cable. An automatic tripping structure 16 is also provided inside the circuit breaker 22. The automatic tripping structure 16 is used to automatically cut off the power supply of the local place. When the infrared camera 3 or the electric current measuring structure 17 monitors that the temperature of the cable in this area of the place is abnormal, the automatic tripping structure 16 automatically cuts off the power supply in the local place, so as to avoid further expansion of the fire caused by electrical reasons.

[0054] As Figure 6 shown, the control system includes a central controller. The central controller is communicatively connected to the local control room, and the local control room is connected to the local fire control system through the Internet. The central controller is used to receive the data detected by the spraying mechanism and the shutdown mechanism, and send operation instructions to the spraying mechanism and the shutdown mechanism. The central controller also sends the position of the fire to the local control room through communication. When a fire occurs, the local control room also sends the fire situation in this area to the local fire control system at the same time, so as to facilitate the local fire department and the firefighters in this place to make a quick response.

[0055] The central controller is also connected to a central wireless data processing center through communication. The central wireless data processing center is connected to an A local area network wireless transmission and reception module and a B local area network wireless transmission and reception module through wireless communication. The A local area network wireless transmission and reception module is electrically connected to an electromagnet, an angle sensor, a pressure gauge, a spray valve, and a stepping motor. The B local area network wireless transmission and reception module is electrically connected to a current measurement structure and an automatic tripping structure. The A local area network wireless transmission and reception module is used to detect the operation data of the spraying mechanism and also receive the spraying mechanism operation instructions sent by the central controller to realize the automatic operation of the spraying mechanism. The B local area network wireless transmission and reception module is used to detect the operation data of the shutdown mechanism and also receive the shutdown mechanism operation instructions sent by the central controller to realize the automatic operation of the shutdown mechanism.
