Description

Technical Field

[0001] This invention belongs to the field of fire monitoring technology, and in particular relates to a fire early warning monitoring device for smart parks and a distributed monitoring system with the same. Background Technology

[0002] A park refers to a group of standard buildings or buildings that are generally planned and constructed by the government (or in cooperation with private enterprises), with complete and reasonable layout of water supply, power supply, gas supply, communication, roads, warehousing and other supporting facilities, and can meet the needs of production and scientific experiments in a specific industry. It includes industrial parks, industrial parks, logistics parks, urban industrial parks, science and technology parks, creative parks, etc.

[0003] The aforementioned industrial park contains a large number of cables and electrical equipment. According to statistics, fires in the city are mainly caused by two types of reasons: one is the insulation damage of electrical equipment, which generates electric arcs and eventually causes a fire; the other is heat generation, which causes flammable materials to burn due to high temperatures, and electrical fires are the most common.

[0004] For example, CN109432676B discloses a networked monitoring and linkage fire extinguishing system for building fire protection facilities, which includes a fire detection mechanism and a fire extinguishing mechanism installed in the building. The fire detection mechanism includes a smoke detector, a heat detector, an infrared detector head, and a central controller. For industrial parks, simply setting up smoke detectors, heat detectors, and infrared detector heads for fire detection is problematic in practice. For instance, when someone smokes or engages in other activities that generate non-fire smoke, the system is prone to overheating. Another example is CN217954198U, a fire smoke detection device for building fire protection, which includes a smoke detector mounting base. The two side walls of the smoke detector mounting base are provided with snap-on mounting structures, and the top of the smoke detector mounting base is snapped with a smoke detector through the snap-on mounting structures. A second strong magnetic ring is fitted around the outer ring of the smoke detector. When this fire smoke detection device is in use, the smoke detector is in long-term contact with dusty air, which can easily cause dust to accumulate on the smoke detector, affecting its sensitivity over time. Summary of the Invention

[0005] The purpose of this invention is to provide a fire early warning and monitoring device for smart parks. By placing a smoke sensor between the upper and lower housings, when the smoke sensor needs to be activated, the movement of the upper and lower housings is controlled to allow the smoke sensor to come into contact with the outside air. This avoids the smoke sensor being exposed to dusty air for a long time, which would cause dust to accumulate on the surface of the smoke sensor and solves the problem of the sensitivity of existing smoke sensors being affected.

[0006] The present invention also aims to provide a distributed monitoring system for smart parks. During the monitoring process, the system first uses temperature sensors and smoke sensors to roughly determine the location of fire hazards. Then, it uses a 360° camera to collect and analyze image information to obtain the specific location of the hazard. This avoids data redundancy caused by traditional camera-based monitoring and improves the accuracy of fire early warning monitoring.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0008] This invention relates to a fire early warning and monitoring device for a smart park, comprising an upper shell and a lower shell that cooperate with each other; it also includes a drive structure A connected to the upper shell and driving it to rotate along the lower shell, and a drive structure B for driving the lower shell to move up and down in the vertical direction; the upper shell has two ventilation holes at its end, which are centrally symmetrical; a smoke sensor is installed inside the lower shell, and a temperature sensor is installed on the top of the upper shell.

[0009] As a preferred embodiment of the present invention, the drive structure A includes a rotary motor connected to the upper surface of the upper housing; the drive structure B includes a telescopic module disposed on the bottom side of the lower housing; a barrier is connected to the port of the lower housing by at least two pillars, and a gap is formed between the barrier and the port of the lower housing.

[0010] As a preferred embodiment of the present invention, it includes a frame, wherein the rotary motor and the telescopic module are respectively installed on the two opposite inner sidewalls of the frame.

[0011] As a preferred embodiment of the present invention, the top periphery of the upper housing is provided with an outwardly protruding ring, and the upper surface of the protruding ring is provided with an annular groove; a support ring that cooperates with the protruding ring is provided between the two inner sidewalls of the frame, and the support ring is provided with a plurality of ball / spherical protrusions on the side near the protruding ring; the telescopic module is a pneumatic telescopic assembly, which is connected to an air supply pump.

[0012] As a preferred embodiment of the present invention, the bottom of the frame is provided with a support module that supports the bottom side of the lower housing; the bottom of the frame is also provided with a mounting bracket, the support module is mounted on a support rod, and the support module is an elastic telescopic rod; when the telescopic module is fully retracted, the support module supports the bottom side of the lower housing.

[0013] As a preferred embodiment of the present invention, a first one-way valve is provided on the pipeline between the air supply pump and the pneumatic telescopic assembly, and a branch pipeline is connected to the pipeline between the first one-way valve and the air supply pump. A second one-way valve is provided on the branch pipeline, and the end of the branch pipeline is connected to a purging mechanism installed inside the enclosure. The purging mechanism is provided with air nozzles distributed radially.

[0014] As a preferred embodiment of the present invention, during installation, the end of the smoke sensor protrudes slightly from the upper port of the lower housing, the starting pressure of the second one-way valve is greater than the starting pressure of the first one-way valve, and a pressure gauge is connected to the pipeline located between the first one-way valve and the air supply pump.

[0015] When in use, when the air supply pump is started, the first one-way valve is opened and the pneumatic telescopic component extends. After the pneumatic telescopic component extends to its maximum length, the air supply pump continues to blow air. At this time, the second one-way valve is opened, and air is blown to the surrounding area through the air outlet.

[0016] A distributed monitoring system for a smart park, wherein the smart park is divided into several monitoring areas, and the length and width of any monitoring area are both L;

[0017] A 360° camera is installed at the center of any monitoring area to monitor that area.

[0018] Furthermore, four fire early warning monitoring devices as described above are installed within the monitoring area. The fire early warning monitoring devices are located diagonally across the monitoring area, and the distance between the fire early warning monitoring devices and the 360° camera is 0.3L-0.6L.

[0019] It also includes a processor connected to the fire early warning monitoring device and the 360° camera package.

[0020] As a preferred embodiment of the present invention, the monitoring method includes:

[0021] Step 1: When the temperature sensor on a fire early warning monitoring device in the monitoring area detects a fire hazard, the 360° camera in the monitoring area is controlled to acquire images of the corresponding location of the fire early warning monitoring device. The images are then analyzed by the processor. After analysis, it is determined whether a fire hazard has occurred in the monitoring area. If so, proceed directly to Step 4; otherwise, proceed to Step 2.

[0022] Step 2: Control the lower housing of the fire early warning monitoring device to move downwards and simultaneously drive the upper housing to rotate slowly. When the smoke sensor detects a signal, the wind direction is determined and analyzed to roughly determine the location of the fire hazard.

[0023] Step 3: Control the 360° camera in the monitoring area corresponding to the location of the fire hazard in Step 2. Use the 360° camera to acquire images of the fire hazard location and analyze the images through the processor. After analysis, determine whether a fire hazard has occurred in the monitoring area. If so, proceed directly to Step 4; otherwise, end the process.

[0024] Step 4: The processor controls the alarm module to issue an alarm.

[0025] As a preferred technical solution of the present invention, in the initial stage, the line connecting the two ventilation holes on the fire early warning monitoring device is perpendicular to the line connecting the fire early warning monitoring device and the 360° camera.

[0026] The present invention has the following beneficial effects:

[0027] This invention places the smoke sensor between the upper and lower housings. When the smoke sensor needs to be activated, the movement of the upper and lower housings is controlled to allow the smoke sensor to come into contact with the outside air. This avoids the smoke sensor being exposed to dusty air for a long time, which would cause dust to accumulate on the surface of the smoke sensor and solves the problem of the sensitivity of existing smoke sensors being affected.

[0028] This invention utilizes a monitoring system that, during the monitoring process, first uses the combination of temperature and smoke sensors to roughly determine the location of a fire hazard, and then uses a 360° camera to collect and analyze image information to obtain the specific location of the hazard. This avoids data redundancy caused by traditional camera-based monitoring and improves the accuracy of fire early warning monitoring.

[0029] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0041] Please see Figure 1-2 As shown in Figures 5-6, the present invention is a fire early warning and monitoring device for a smart park, comprising a rectangular frame 3, with a drive structure A and a drive structure B fixed at the top and bottom of the frame 3 respectively; the end of a rotary motor 21 is connected to an upper housing 1 and drives the upper housing 1 to rotate, while the end of the drive structure B abuts against a lower housing 2 and drives the lower housing 2 to move up and down in the vertical direction, a smoke sensor is installed inside the lower housing 2, and a temperature sensor is set at the top of the upper housing 1; and the lower housing 2 is fitted inside the upper housing 1.

[0042] Of course, based on the above, drive structure A is a rotary motor 21, drive structure B is a telescopic module 22, specifically a pneumatic telescopic component, and it is connected to an air supply pump 23.

[0043] To facilitate the contact between the smoke sensor and the outside air when the smoke sensor needs to be activated, the movement of the upper and lower housings is controlled; for example... Figure 3-4In this invention, the upper housing 1 has two ventilation holes 11 at its end, and the two ventilation holes 11 are centrally symmetrical; and the lower housing 2 has a barrier 202 connected to its port by at least two pillars 201, and a gap is formed between the barrier 202 and the port of the lower housing 2.

[0044] Furthermore, in practical use, when the smoke sensor is activated, the pneumatic telescopic component extends to its maximum length, causing the lower housing 2 to move upwards in the vertical direction. At this time, the height of the gap gradually increases until the gap coincides with the position of the ventilation hole 11. When the smoke sensor is deactivated, the pneumatic telescopic component retracts to its shortest length. At this time, the enclosure 202 blocks the ventilation hole 11, and the end of the upper housing 1 blocks the gap, thereby preventing the cavity formed by the lower housing 2 and the upper housing 1 from communicating with the outside for gas exchange.

[0045] It is understood that, in this invention, as Figure 1-2 The top periphery of the upper housing 1 is provided with a protruding ring 12 that protrudes outward, and the upper surface of the protruding ring 12 is provided with an annular groove; a support ring 31 that cooperates with the protruding ring 12 is provided between the two inner side walls of the frame 3. The support ring 31 is provided with several ball / spherical protrusions on the side of the support ring 31 near the protruding ring 12. The support ring 31 is used to support the upper housing 1 and avoid possible damage to the rotary motor 21 caused by the long-term suspension of the upper housing 1.

[0046] It is understood that in this invention, the bottom of the frame 3 is provided with a support module that supports the bottom side of the lower housing 2; the bottom of the frame 3 is also provided with a mounting bracket 30, the support module is mounted on the mounting bracket 30, and the support module is selected as an elastic telescopic rod 33; when the telescopic module 22 is fully retracted, the support module supports the bottom side of the lower housing 2.

[0047] Of course, since smoke sensors are frequently activated due to non-fire-related reasons, dust easily accumulates on their surface over long-term use. To avoid dust interference, the dust on the surface of the smoke sensor needs to be cleaned promptly. Therefore, in this application, if... Figure 7 A first check valve 24 is provided on the pipeline 231 between the air supply pump 23 and the pneumatic telescopic assembly. A branch pipeline 251 is connected to the pipeline 231 between the first check valve 24 and the air supply pump 23. A second check valve 25 is provided on the branch pipeline 251. The end of the branch pipeline 251 is connected to a purging mechanism 26 provided in the enclosure 202. The purging mechanism 26 is provided with radially distributed air outlets 261.

[0048] That is, during installation, the end of the smoke sensor protrudes slightly from the upper port of the lower housing 2, the starting pressure of the second one-way valve 25 is greater than the starting pressure of the first one-way valve 24, and a pressure gauge 232 is connected to the pipeline 231 between the first one-way valve 24 and the air supply pump 23.

[0049] When in use, when the air supply pump 23 is started, the first one-way valve 24 is opened and the pneumatic telescopic component extends. After the pneumatic telescopic component extends to its maximum length, the air supply pump 23 continues to blow air. At this time, the second one-way valve 25 is opened, and air is blown to the surrounding area through the air outlet 261. The air blows away the dust attached to the surface of the smoke sensor and discharges it through the gap from the cavity formed by the lower housing 2 and the upper housing 1.

[0050] Of course, in order to facilitate the lower housing 2 to return to its initial position after the air supply pump 23 stops supplying air, the pneumatic telescopic component in this invention is connected to the exhaust pipe 28, and a control valve 281 is connected to the end of the exhaust pipe 28. After the detection is completed, the control valve is opened, and the lower housing 2 moves downward under its own weight. When it is necessary to control the pneumatic telescopic component to extend again, the control valve 281 is closed.

[0051] Meanwhile, in order to avoid excessive air pressure inside the pneumatic telescopic assembly, the pneumatic telescopic assembly in this invention is connected to an overflow pipe 271, the end of which is connected to a third one-way valve 27, and the starting pressure of the third one-way valve 27 is greater than that of the first one-way valve 24.

[0052] like Figure 8 A distributed monitoring system for a smart park is disclosed, comprising several monitoring areas 100 within the smart park, each monitoring area 100 having a length and width of 10m; a 360° camera 101 is installed at the center of each monitoring area 100 to monitor the area within that monitoring area; four fire early warning monitoring devices 102 are installed within each monitoring area 100, positioned diagonally across the monitoring area 100, with each fire early warning monitoring device 102 being 5m away from the 360° camera 101; and a processor is also included that is connected to the fire early warning monitoring devices 102 and the 360° camera 101.

[0053] As a preferred embodiment of the present invention, the monitoring method includes:

[0054] Step 1: When the temperature sensor on a fire early warning monitoring device 102 in the monitoring area 100 detects a fire hazard, the 360° camera 101 in the monitoring area 100 is controlled to acquire an image of the corresponding position of the fire early warning monitoring device 102 and the image is analyzed by the processor. After analysis, it is determined whether a fire hazard has occurred in the monitoring area 100. If so, proceed directly to step 4; otherwise, proceed to step 2.

[0055] In step 1, when the temperature sensor detects that the temperature at the corresponding location is higher than the set value, it is determined that a fire hazard has occurred near the fire prevention and early warning monitoring device 102.

[0056] Step 2: Control the lower housing 2 on the fire early warning monitoring device 102 to move downwards and simultaneously drive the upper housing 1 to rotate slowly. When the smoke sensor detects a signal, the wind direction is determined and analyzed to roughly determine the location of the fire hazard.

[0057] Step 3: Control the 360° camera 101 in the monitoring area 100 corresponding to the location of the fire hazard in Step 2, use the 360° camera 101 to acquire images of the location of the fire hazard, and analyze the images through the processor. After analysis, determine whether a fire hazard has occurred in the monitoring area 100. If so, proceed directly to Step 4; otherwise, end the process.

[0058] Step 4: The processor controls the alarm module to issue an alarm.

[0059] In the initial stage, the line connecting the two ventilation holes 11 on the fire early warning monitoring device 102 is perpendicular to the line connecting the fire early warning monitoring device 102 and the 360° camera 101.

[0060] Attached below Figure 8 As shown, the four adjacent fire early warning monitoring devices 102 in the four monitoring areas 100 are marked as P1, P2, P3 and P4 respectively. When a fire hazard is detected at the P4 position, the temperature detected by the temperature sensors at the P1, P2 and P3 positions is judged. When the temperature of P1 is the highest among the three points, or when the temperature of P2 is the highest among the three points and P1 is higher than P3, the upper housing 1 is controlled to rotate clockwise; when the temperature of P1 is the highest among the three points, or when the temperature of P2 is the highest among the three points and P3 is higher than P1, the upper housing 1 is controlled to rotate counterclockwise.
