[ first embodiment ]

Referring to fig. 1-5, the present embodiment provides an active fire suppression system 100. Referring to fig. 1, an active fire extinguishing system 100 is adapted to be installed in a space PL (e.g., a factory building), the active fire extinguishing system 100 includes an external device 1 and a control module 2 electrically coupled to the external device 1, and the active fire extinguishing system 100 can control the external device through the control module 2, so that the external device 1 detects a fire source (i.e., a fire point) and accurately sprays a fire extinguishing agent on the fire source to extinguish the fire.

In other words, any fire suppression system that does not directly extinguish a fire source (e.g., a pipeline fire suppression system with extensive sprinkler) is not intended to be an active fire suppression system 100 of the present invention. Next, the components of the active fire suppression system 100 and their connections will be described.

As shown in fig. 1 and 2, the external device 1 is disposed in the space PL, and is particularly preferably mounted on a ceiling CE of the space PL, but the present invention is not limited thereto. The external device 1 includes an image photographing unit 11, a belt driving mechanism 12, a temperature photographing unit 13, and a fire extinguishing sight 14.

Referring to fig. 1, fig. 2, and fig. 4, the image capturing unit 11 is a CCD camera (CCD camera) in the present embodiment, but the present invention is not limited thereto. The image capturing unit 11 is disposed on the ceiling CE and faces any one direction of the space PL, so that the image capturing unit 11 has an image detection range VR in the space PL. The image detection range VR is defined with a plurality of identification blocks (as shown in fig. 4), and the position of each identification block can correspond to an area of the space PL. The image capturing unit 11 can capture a plurality of identification images within the image detection range VR according to a time axis, that is, each identification image is provided at each time point. A plurality of said identification images can be acquired (or read) by said control module 2.

The driving mechanism 12 is disposed on the ceiling CE in this embodiment and is located at a position that does not affect the image capturing unit 11 to obtain the identification image. In this embodiment, the driving mechanism 12 includes a stepping motor (not shown) and a mounting bracket (not shown), the stepping motor is electrically coupled to the control module 2, and the stepping motor can be controlled (or driven) by the control module 2. The mounting rack can be driven by the stepping motor to swing towards the image detection range VR. That is, the driving mechanism 12 can be controlled by the control module 2 to swing so as to face any one of the identification blocks. Of course, the stepping motor can be adjusted to other driving members (e.g., servo motor) as appropriate.

The temperature photographing unit 13 is an infrared thermal imager (IR Camera) in the embodiment, but the present invention is not limited thereto. The temperature photographing unit 13 is disposed on the driving mechanism 12, and the temperature photographing unit 13 can be driven by the driving mechanism 12 to face any one of the identification blocks, so that the temperature photographing unit 13 can obtain the temperature in any one of the identification blocks, and the temperature can be obtained (or read) by the control module 2.

The fire suppression sight 14 is disposed on the actuator 12, and the fire suppression sight 14 can be used to connect a fire suppressant. In practice, the fire extinguishing gun 14 may be the fire extinguishing agent connected by a pipeline (e.g., a water pipe) as liquid water, or connected by a compressed bottle as fire extinguishing dry powder, i.e., the fire extinguishing agent is herein referred to as any liquid or powder capable of extinguishing a fire source.

In addition, the fire suppression sight 14 is electrically coupled to the control module 2 and is controllable by the control module 2 such that the fire suppression sight 14 sprays the fire suppression agent toward a target area. That is, the fire fighting sight 14 in this embodiment includes an electrically controlled valve (not shown) controlled by the control module 2.

Referring to fig. 3 again, the control module 2 is electrically coupled to the image photographing unit 11, the driving mechanism 12, the temperature photographing unit 13 and the fire extinguishing sight 14 in this embodiment, and the control module 2 can integrate the image photographing unit 11, the driving mechanism 12, the temperature photographing unit 13 and the fire extinguishing sight 14, so as to achieve the effects of detecting the fire source, extinguishing the fire source and the like.

Specifically, the control module 2 can obtain two identification images at different time points, and determine whether any one of the identification blocks has a smoking image according to the change between the two identification images. In other words, the control module 2 can detect that any one of the identification blocks is a smoke generating block through a plurality of the identification images.

In this embodiment, the control module 2 compares the identification image at the current time point with one identification image as a comparison, and determines whether the fuming image occurs or not by using a gray level variation value therebetween.

Specifically, as shown in fig. 4 and 5, the control module 2 obtains one of the identification images before smoke emission as a comparison group (hereinafter, referred to as a comparison image OR) in advance through the image capturing unit 11, and the control module 2 calculates an average gray level corresponding to each of the identification blocks in the comparison image OR. Next, the control module 2 compares the comparison image OR with the identification image RI at the current time point, and determines whether a difference (OR a variation) between the average gray-scale value in the comparison image OR corresponding to the same region (i.e. the same identification block) and the average gray-scale value in the identification image RI at the current time point is greater than a determination value.

For example, the comparison image OR is shown in fig. 4, and the recognition image RI at the current time point is shown in fig. 5. The image detection range in the comparison image in FIGS. 4 and 5 is coordinated and defined as 1-9 in order from left to right and A-E in order from top to bottom. That is, the image detection ranges in fig. 4 and 5 form a plurality of 9-by-5 square areas after being coordinated, and each square area represents the identification block.

Assuming that the device in the C6 box area is smoking, the control module 2 finds that the average gray-level value of the identification image RI at the current time point in the C6 box area is suddenly changed (e.g., suddenly increased or decreased) compared to the average gray-level value of the comparison image in the C6 box area, and exceeds the determination value. The control module 2 determines that (the identification block RI of) the C6 box area has the smoking image SD, and further defines it as a smoking block TA.

Of course, the manner in which the control module 2 determines whether any one of the recognition blocks has the fuming image SD is not limited to the above description. For example, the control module 2 may also recognize whether the fuming image SD exists through the variation of RGB values, a convolutional neural network, or the like.

As shown in fig. 5, after the control module 2 detects that any one of the identification blocks is the smoke generating block TA, the control module 2 can control the driving mechanism 12 to drive the temperature photographing unit 13 to face the smoke generating block TA, so as to obtain a first detection temperature. Then, the control module 2 can control the driving mechanism 12 to drive the fire-extinguishing gun 14 when the first detected temperature exceeds a burning point temperature, so that the fire-extinguishing gun 14 sprays the fire-extinguishing agent toward the smoke generating block TA (i.e., the block area C6 in fig. 5).

That is, the active fire extinguishing system 100 determines the location of the fire source by using two conditions, i.e., smoke generation and high temperature, and further extinguishes the fire source. In other words, any fire extinguishing system that determines the fire source by using two conditions, i.e., smoke generation and high temperature, is not the active fire extinguishing system 100 of the present invention.

It is noted that, in order to avoid slight differences in the actual positions of the identification areas and the space PL (e.g., image distortion caused by wide-angle lenses), the fire extinguishing target 14 may not effectively (or accurately) extinguish the fire source.

Therefore, in a preferred embodiment, after the fire extinguishing gun 14 sprays the fire extinguishing agent toward the smoke generating block TA for a determined time (e.g., 5 minutes), the control module 2 obtains a second detected temperature of the smoke generating block TA again through the temperature photographing unit 13. When the control module 2 determines that the second detected temperature is greater than the ignition temperature, the fire-extinguishing gun 14 is driven by the driving mechanism 12, so that the fire-extinguishing gun 14 can spray the fire-extinguishing agent toward the eight identification blocks (i.e., the block areas B5-B7, C5, C7, D5-D7 in fig. 5) adjacent to the smoke generating block TA. Accordingly, the fire fighting sight 14 can be centered on the smoke generating block TA and further expand the spray range of the fire extinguishing agent.

In practice, the fire fighting sight 14 sprays the fire fighting agent toward the eight identification blocks adjacent to the smoke generating block TA, as the case may be. Two preferred embodiments are provided below, but the present invention is not limited thereto.

In one preferred embodiment, the fire extinguishing gun 14 can be driven by the driving mechanism 12 to spray the fire extinguishing agent toward eight identification blocks adjacent to the smoke generating block TA one by one. For example, the smoke generating block TA is a C6 box area, and the fire-extinguishing gun 14 is driven by the driving mechanism 12 and sequentially sprays the fire-extinguishing agent for a specific time toward the eight identification blocks in the B5-B7, C5, C7, D5-D7 box areas.

In another preferred embodiment, the fire extinguishing sight 14 comprises a nozzle (not shown) capable of spraying the fire extinguishing agent and a spray angle adjusting member (not shown) disposed on the nozzle, wherein the spray angle adjusting member can adjust the spray angle of the fire extinguishing agent when the fire extinguishing agent leaves the nozzle, so that the fire extinguishing agent can cover eight identification blocks adjacent to the smoking blocks. It can also be understood that the fire extinguishing agent sprayed by the spray head is adjusted to be conical by the spray angle adjusting piece from a column shape, so that the fire extinguishing agent can cover the eight identification blocks and the smoking blocks TA in the square areas of B5-B7, C5, C7, D5-D7. It should be additionally noted that the adjustment of the spray angle of the fire extinguishing agent when leaving the nozzle by the spray angle adjusting member is the prior art, and is not the key point of the present invention, and therefore, the details are not repeated herein.

[ second embodiment ]

As shown in fig. 6 to 8, which are second embodiments of the present invention, the active fire extinguishing system 100 'of this embodiment is similar to the active fire extinguishing system 100 of the first embodiment, and the same points of the two embodiments are not repeated, and the difference between the active fire extinguishing system 100' of this embodiment and the first embodiment mainly lies in:

as shown in fig. 6 to 8, the active fire extinguishing system 100' of the present embodiment further includes a lifting device 15 installed on the ceiling CE, and the lifting device 15 can be configured for the external device 1. Accordingly, the lifting device 15 can drive the external device 1 to move, so that a user can conveniently clean (or repair) the external device.

Specifically, the lifting device 15 in this embodiment includes a setting seat 151 for being disposed on the ceiling CE and a displacement mechanism 152 mounted on the setting seat 151. The displacement mechanism 152 can drive the external device 1 to move between a working position P1 (shown in fig. 6) and a preparing position P2 (shown in fig. 8). Wherein, when the external device 1 is in the working position P1, the external device 1 is fixed on the installation seat 151, so that the external device 1 can detect and extinguish fire on the ceiling CE. When the external device 1 is at the servicing position P2, the external device 1 is far away from the installation seat 151, so that the external device 1 is close to the ground and can be easily cleaned and repaired by the user.

As shown in fig. 7, in a preferred case, the setting seat 151 includes a coupling groove 1511 and a first conductive member 1512 disposed in the coupling groove 1511, the notch of the coupling groove 1511 is far away from the ceiling CE, and the inner edge of the coupling groove 1511 is disposed with the first conductive member 1512. The first conductive member 1512 is a conductive tab exposed at an inner edge of the coupling slot 1511 in this embodiment, and the first conductive member 1512 is electrically coupled to the control module 2.

The displacement mechanism 152 in this embodiment includes a lifting unit 1521, a mounting table 1522, a second conductive member 1523, and a coupling protrusion 1524. The lifting unit 1521 is a winch in this embodiment, but the present invention is not limited thereto. The elevating unit 1521 is mounted on the installation base 151, and the installation table 1522 is mounted on one end of the elevating unit 1521. The lifting unit 1521 can drive the mounting table 1522 to move (along the vertical direction of the space PL). In practice, the lifting unit 1521 may be other devices (e.g., a rail-type elevator) capable of lifting or lowering, or may be installed on the ceiling CE.

The external device 1 is disposed on the mounting table 1522, and the coupling protrusion 1524 is formed on one side of the mounting table 1522 facing the coupling groove 1511, and the coupling protrusion 1524 can geometrically fit with the coupling groove 1511. The second conductive member 1523 is a conductive tab electrically coupled to the external device 1 in this embodiment, and is disposed at an outer edge of the coupling bump 1524.

When the external device 1 is at the working position P1, the coupling protrusion 1524 is received in the coupling groove 1511, and the external device 1 is electrically coupled to the first conductor 1512 through the second conductor 1523, so that the external device 1 is electrically coupled to the control module 2. On the contrary, when the external device 1 is at the servicing position P2, the coupling protrusion 1524 is away from the coupling groove 1511, so that the second conductor 1523 is separated from the first conductor 1512, and the external device 1 is adjacent to the ground without being electrically coupled to the control module 2.

It should be noted that, the coupling protrusion 1524 and the coupling groove 1511 are aligned in a geometric matching manner, so that the image capturing unit 11 can be effectively ensured to be reset to the working position, and the image detection range VR is not deviated due to being driven by the lifting device 15.

Of course, in practice, the active fire extinguishing system 100' may further include a protective housing 6, and the protective housing 6 is mounted on the mounting table 1522 and covers the image photographing unit 11 and the temperature photographing unit 13 to isolate external dust. Therefore, the protective cover 6 must be made of a material (e.g., a transparent acrylic plate) that does not affect the operation of the image capturing unit 11 and the temperature capturing unit 13. Accordingly, the period of time for which the image photographing unit 11 and the temperature photographing unit 13 need to be cleaned is effectively greatly prolonged.

In addition, in a preferred embodiment, in order to prevent the lifting device 15 from pulling the pipeline of the fire-extinguishing gun 14 during the moving process, the driving mechanism 12 in this embodiment further includes two driving components 121, and each of the driving components 121 includes a stepping motor (not shown) and a mounting bracket (not shown). One of the entraining members 121 is mounted on the lifting device 15 and is used for mounting the temperature photographing unit 13, and the other entraining member 121 is mounted on the ceiling CE and is used for mounting the fire-extinguishing sight 14. Of course, the stepping motor can be adjusted to other driving members (e.g., servo motor) as appropriate.

[ third embodiment ]

As shown in fig. 9, which is a third embodiment of the present invention, the active fire extinguishing system 100 "of this embodiment is similar to the active fire extinguishing system 100 of the first embodiment, and the same points of the two embodiments are not repeated, and the difference between the active fire extinguishing system 100" of this embodiment and the first embodiment mainly lies in:

the active fire extinguishing system 100 ″ of the present embodiment further includes a notification module 3, an on-off module 4, and a reporting module 5 electrically coupled to the control module 2. The active fire extinguishing system 100 ″ can notify a fire to an adjacent fire fighting unit in real time through the notification module 3, and can also prevent the active fire extinguishing system 100 ″ from misjudging through the opening and closing module 4 and the broadcasting module 5 to spray the fire extinguishing agent.

Specifically, the notification module 3 in this embodiment includes a communicator 31 and a player 32, and the communicator 31 can communicate with the fire department in a local manner. The player 32 can play a pre-recorded voice and report the address to the fire department through the communicator 31.

In practical situations, when the control module 2 determines that the first detected temperature is greater than the ignition point temperature, the communicator 31 dials to a fire-fighting unit and plays the pre-recorded voice, so that the fire-fighting unit knows that a fire occurs at the current location and needs assistance. In other words, when the control module 2 determines that the first detected temperature is greater than the ignition temperature, a fire notification can be sent to an adjacent fire-fighting unit.

In addition, in special situations (e.g., when a fire is being grilled in the space), the active fire suppression system 100 "may misjudge the fire source as a fire factor. Therefore, the on-off module 4 and the broadcasting module 5 can effectively prevent the active fire extinguishing system 100 from misjudging to extinguish the fire source.

Specifically, the on-off module 4 is a control switch in this embodiment, and can manually connect and disconnect the electrical relationship between the control module 2 and the external device 1. The broadcast module 5 can send a notification voice when the first detection temperature is higher than the ignition temperature.

In practical situations, when the control module 2 determines that the first detected temperature exceeds the ignition point temperature, the control module 2 can instruct the broadcast module to send the notification voice through a signal, and the control module 2 waits for a waiting second (e.g., 20 seconds). Meanwhile, the user can disconnect the electrical relationship between the control module 2 and the external device 1 through the opening and closing module 4, so as to close the active fire extinguishing system 100 ″ to prevent the fire extinguishing sight 14 from being started.

On the contrary, when the waiting time exceeds the waiting time of seconds, the control module 2 controls the driving mechanism 12 to drive the fire-extinguishing gun 14, so that the fire-extinguishing gun 14 sprays the fire-extinguishing agent toward the smoke-generating block.

[ fourth embodiment ]

Referring to fig. 10, a fourth embodiment is an active fire extinguishing method according to the present invention, which is suitable for the active fire extinguishing system 100 of the first embodiment. Therefore, please match fig. 1 to fig. 5 in due time. Referring to fig. 10, the active fire extinguishing method disclosed in this embodiment includes steps S101 to S117. It should be noted that any one of the above steps can be omitted or replaced with a reasonable variation according to the needs of the designer.

Step S101: a plurality of identification blocks are divided by an image detection range VR. Specifically, the image capturing unit 11 captures an image of the space PL, and the image capturing unit 11 has the image detection range VR in the space PL. The image detection range VR is divided into a plurality of areas and is limited to a plurality of identification blocks.

Step S103: and taking a plurality of identification images within the image detection range VR according to a time axis. In detail, the image capturing unit 11 captures an image of the space PL, and acquires one of the recognition images at each time point.

Step S105: and judging whether any one of the identification blocks has a smoking image or not by using the variation value among the identification images. If yes, go to step S106: defining the identification block with the smoking image as a smoking block, and executing step S107. If not, go to step S103.

In practice, the method of determining the fuming image may be a variation of gray-level values as in the first embodiment, or other methods known to those skilled in the art (for example, variation of RGB values or a convolutional neural network), which will not be described herein again.

Step S107: obtaining a first detection temperature of the smoking block. That is, the temperature of the smoke generating block is acquired by the temperature imaging unit 13.

Step S109: and judging whether the first detection temperature is greater than an ignition point temperature. If yes, go to step S111. If not, go to step S103. Typically, the ignition temperature is 100 degrees Celsius, but in special cases (e.g., chemical plants), the ignition temperature can be adjusted depending on the circumstances. For example: in a space where a large amount of camphor (ignition point 70 degrees celsius) is stored, the ignition point temperature is recommended to be set to 70 degrees celsius.

Step S111: a fire fighting gun 14 is driven to spray a fire extinguishing agent on the smoke generating block for a determined time. It should be noted that the active fire extinguishing system 100 can be found in real time when a fire occurs, so that the determination time is mostly not more than 10 minutes to extinguish the fire source, but in practice, the determination time can be adjusted according to the environment.

Of course, while step S111 is executed, the notification module 3 and the broadcast module 5 (as shown in fig. 9) can be used to notify fire-fighting units and persons (for example, light and voice notification).

Step S113: and acquiring a second detection temperature of the smoking block. That is, the temperature of the smoke generating block is obtained again by the temperature photographing unit 13.

Step S115: and judging whether the second detection temperature is greater than the ignition temperature. If yes, go to step S117. If not, go to step S103.

Step S117: the fire fighting sight 14 is driven to spray the fire extinguishing agent toward the eight identification blocks adjacent to the smoking block. In general, there may be a deviation between the smoke generating block in the recognition image and the actual fire source. The fire suppression sight 14 sprays the fire suppressant toward eight of the identification blocks adjacent to the smoke generating block at this step, thereby widening the range of spraying of the fire suppressant. In practice, the fire extinguishing agent is continuously sprayed within 10 minutes, and most of the just-ignited flames (or the fire source) can be extinguished in real time through the steps.

[ technical effects of the embodiments of the present invention ]
