Description

Technical Field

[0001] The present invention belongs to the technical field of rail transit monitoring, and in particular relates to a rail transit machine room safety early warning device and method. Background Art

[0002] With the acceleration of urbanization, the rail transit system, as the backbone network of urban public transportation, is directly related to the daily operation of the city and the quality of life of residents. The rail transit computer room is the core control area of ​​the system, and the stability of its environmental conditions has a vital impact on the overall performance of the system. Among them, dust is one of the common pollutants in the computer room, and its presence poses a serious threat to equipment performance, operating efficiency and even overall safety.

[0003] Dust contains a large number of tiny particles, which easily adhere to the surface and interior of equipment in the room, affecting the heat dissipation performance of the equipment. Long-term accumulation will cause the temperature of the equipment to rise, which will lead to performance degradation, shortened lifespan and even frequent failures. For example, the equipment in the communication room may cause poor heat dissipation due to dust coverage, which may trigger overheating protection and affect the quality of signal transmission. Particles in dust may also reduce the insulation of electrical equipment and increase the risk of short circuits and fires. Especially in humid air environments, the moisture in the dust combines with the particles to form a conductive path, posing a direct threat to the electrical safety of the equipment.

[0004] At present, the management of dust in rail transit machine rooms mainly relies on regular manual cleaning and inspection, which has obvious limitations: manual cleaning is not only time-consuming and labor-intensive, but also difficult to be comprehensive and thorough, especially in machine rooms with dense equipment and narrow space, the cleaning effect is often greatly reduced. Regular inspections cannot reflect the changes in dust in the machine room in real time. Once dust accumulates to a certain extent, it often causes irreversible damage to equipment performance.

[0005] Therefore, there is an urgent need for a rail transit machine room safety warning device and method that can monitor the dust situation in the machine room in real time and issue a warning, reduce equipment failure rate, and improve the overall performance of the system. Summary of the invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a rail transit machine room safety warning device and method, which can monitor and warn the dust situation in the air in the machine room in real time to ensure the normal operation of the equipment in the machine room and the stability of the system.

[0007] In order to achieve the above object, the technical solution of the present invention is as follows: A rail transit machine room safety warning device comprises: a first acquisition component and a control module; the first acquisition component comprises a carrier; an active cavity is arranged in the carrier; an opening is arranged on one side of the active cavity; a plurality of discs are arranged in the active cavity, and a preset distance is set between the discs and the active cavity; a rotating shaft is arranged at the axis of the disc; the rotating shaft runs through the axis of all the discs, and the rotating shaft and the discs are fixedly connected; a third channel and a plurality of second channels are arranged in the rotating shaft, the third channel is arranged radially along the rotating shaft, the third channel is connected to the outside, and the second channel is used to introduce the fluid near the axis of the disc into the third channel; a driving member for driving the rotating shaft to rotate is arranged at one end of the rotating shaft, and the driving member is electrically connected to the control module; a transparent adsorption layer is arranged at the position of the disc away from the axis; a light-emitting member, an image acquisition module and a warning module are also arranged in the carrier, the light-emitting member is used to emit light to the transparent adsorption layer, the image acquisition module is used to obtain image information after the light passes through the transparent adsorption layer, and the warning module is used to send warning information; the control module is used to judge the dust pollution situation based on the image information and control the operation of the warning module.

[0008] The above scheme has the following beneficial effects: 1. This scheme, by passing the air flowing out of the machine room into the active cavity from the opening, the driving member drives the shaft to rotate, the rotation of the shaft drives the disc to rotate, the rotation of the disc drives the air in the active cavity to make a spiral centripetal motion, and then enters the third channel through the second channel, and then is discharged through the third channel; when the air moves between the discs, the dust in the air is charged with static electricity due to the shear between the disc and the air, and adheres to the transparent adsorption layer, the control module starts the light emitting member to emit light, after the light passes through the transparent adsorption layer, it is collected by the image sensor, the control module uses the image information collected by the image sensor to judge the dust content in the air, when the dust content is higher than the preset value, the control warning module sends a warning message.

[0009] Compared with the existing technology, this solution effectively promotes the electrostatic adhesion of dust particles in the air to the transparent adsorption layer through the spiral centripetal motion generated by the rotation of the disc. This process not only improves the dust removal efficiency, but also makes the dust collection intuitive and easy to monitor. Combined with the light-emitting component and the image acquisition module, it can capture and analyze the dust on the transparent adsorption layer in real time, realizing efficient and continuous monitoring of the air quality in the computer room.

[0010] 2. In this solution, the control module intelligently judges the dust pollution situation based on the image information provided by the image acquisition module. When the dust content is detected to exceed the preset safety threshold, the early warning module is automatically triggered to send an early warning message, which helps the computer room managers to take timely measures to prevent dust accumulation from damaging the computer room equipment and ensure the stable operation of the rail transit system.

[0011] 3. Compared with the traditional manual inspection method, this device can realize automatic and intelligent monitoring and early warning, greatly reducing the labor cost and time cost. At the same time, through timely early warning and processing, it can effectively avoid the damage to the equipment caused by dust accumulation, and further reduce the cost of repairing and replacing equipment.

[0012] Furthermore, a first cleaning component is also provided at the opening of the movable cavity; the first cleaning component includes a three-way pipe; one of the outlets of the three-way pipe is connected to a water tank, the water tank is filled with cleaning agent, a first valve is provided at the connection between the water tank and the three-way pipe, and the first valve is electrically connected to the control module; the other outlet of the three-way pipe is connected to the opening.

[0013] Beneficial effect: The control module opens and closes the first valve to allow the cleaning agent in the water storage tank to flow into the three-way pipe and then into the active cavity, and uses the rotation of the disc to drive the cleaning agent to flush on the surface of the disc. This rotating flushing method can more thoroughly remove dust and dirt attached to the transparent adsorption layer, and maintain the cleanliness and light transmittance of the transparent adsorption layer. The cleaned transparent adsorption layer can more accurately reflect the dust pollution in the machine room, thereby improving the accuracy of the image acquisition module in obtaining image information. This helps the control module to more accurately judge the dust content and trigger corresponding early warning measures.

[0014] Furthermore, a second cleaning component is also provided on the carrier; the second cleaning component includes a plurality of functional cavities, each of which is arc-shaped; the functional cavities are respectively located between the disks and between the disks and the movable cavities; an arc block is provided in the functional cavity, and the fixed end of the arc block is rotatably connected to the functional cavity; a baffle and a receiving groove are also provided on the side of the functional cavity close to the movable cavity, the baffle and the receiving groove are slidably matched, and the receiving groove is connected to all the functional cavities; a first transmission component is provided on the baffle, the first transmission component is used to control the lifting and lowering of the baffle, and the first transmission component is electrically connected to the control module; a second transmission component is also provided on the arc block, and the second transmission component is used to control the deflection of the arc block based on the lifting and lowering of the baffle.

[0015] Beneficial effect: the baffle is moved upward by the first transmission component, and the lifting of the baffle is converted into a deflection angle of the arc block by the second transmission component. The arc block is deflected from the functional cavity to the surface of the disc. When the disc rotates, the arc block can scrape off the dust on the surface of the disc. When the cleaning agent flows into the third channel, the scraped dust is taken away at will, thereby improving the cleaning effect of the transparent adsorption layer.

[0016] The unique arc-shaped functional cavity design combined with the deflectable arc block achieves deep cleaning of the disc surface, especially the hard-to-reach areas adjacent to the disc. When the arc block is deflected to the disc surface under the drive of the baffle, as the disc rotates, the arc block can effectively scrape off the dust and stains on the surface, significantly improving the cleaning efficiency and quality. At the same time, the design of the arc-shaped functional cavity and arc block not only saves space, but also improves the integrity and integration of the equipment.

[0017] Furthermore, the first transmission component includes a circular ring; the circular ring rotates in cooperation with the rotating shaft; a circular groove is provided on one side of the circular ring close to the rotating shaft, and a first channel is also provided on the rotating shaft, and the first channel is used to connect the third channel with the circular groove; a protrusion is also provided at the connection point between the third channel and the circular groove, and the protrusion is used to reduce the cross-sectional area of ​​the third channel; the circular groove is also connected to a connecting pipe, and the other end of the connecting pipe is connected to a sealing chamber; the sealing chamber is located above the baffle; an elastic cushion layer is provided in the sealing chamber; the bottom of the sealing chamber is connected to the accommodating groove, and a lifting shaft is provided at the bottom of the elastic cushion layer, and the lifting shaft extends into the accommodating groove, the lifting shaft is fixedly connected to all baffles, and the lifting shaft is slidably matched with the accommodating groove; a branch pipe is also provided on the connecting pipe, and the branch pipe is used to connect the connecting pipe with the outside world; a second valve is also provided at the connection point between the branch pipe and the connecting pipe, and the second valve is electrically connected to the control module.

[0018] Beneficial effect: When the first transmission component is running, the second valve is controlled to close through the control module. At this time, when the fluid (air or cleaning agent) flows through the protrusion, the flow rate increases, and the air pressure in the first channel decreases, thereby reducing the air pressure in the annular groove, the connecting pipe, and the functional cavity, thereby causing the elastic cushion layer to deform. The deformation of the elastic cushion layer drives the lifting shaft to move upward, thereby realizing the movement of the baffle.

[0019] This solution uses the flow rate increase effect of fluid (such as air or cleaning agent) flowing through the protrusion to form an air pressure difference in the first channel. This air pressure difference directly acts on the elastic cushion layer in the sealing cavity to achieve rapid response and precise control of non-mechanical transmission. This pneumatic control method is not only highly efficient, but also reduces mechanical wear and extends the service life of the equipment.

[0020] Through the connection between the control module and the second valve, the flow of the fluid is precisely controlled. The second valve can be opened or closed by the control module as needed to control the flow direction and flow rate of the fluid and achieve precise adjustment of the movement of the baffle. This intelligent control method improves the automation of the equipment, reduces manual intervention, and improves work efficiency.

[0021] Furthermore, the second transmission assembly includes a plurality of racks, which are fixedly connected to the lifting shaft; the racks are respectively engaged with worm wheels; the turbines are respectively engaged with worms; the bottoms of the worms extend into the functional cavity, and the bottoms of the worms are fixedly connected to the fixed ends of the arc blocks.

[0022] Beneficial effect: When the lifting shaft rises or falls, it will drive the rack on the lifting shaft to move synchronously, the rack drives the worm wheel to rotate, the worm wheel rotates to drive the worm, and the worm rotates to drive the arc block to deflect. The fixed connection between the rack and the lifting shaft ensures that the movement of the lifting shaft can be directly and accurately transmitted to the rack. The meshing of the rack and the worm wheel, and the meshing of the worm wheel and the worm, form a stable transmission chain, so that the movement of the lifting shaft can be accurately converted into the rotational movement of the worm, thereby driving the arc block to deflect. This precise transmission control helps to realize complex mechanical movements and improve the overall performance of the equipment.

[0023] Furthermore, the preset distance is twice the boundary layer thickness of the fluid.

[0024] Beneficial effect: By setting the preset distance between the discs to twice the boundary layer thickness of the fluid, the two boundary layer areas will touch each other, thereby reducing the free flow area of ​​the fluid between the discs. This free flow area usually does not effectively transfer energy to the discs and contributes little to torque generation. Reducing the free flow area means that more fluid energy is used to drive the discs to rotate, thereby improving the efficiency of the disc rotation.

[0025] Furthermore, the transparent absorption layer is made of transparent rubber.

[0026] Beneficial Effects: The transparent rubber has excellent adhesion properties, effectively capturing and adsorbing dust particles in the air.

[0027] Furthermore, the cleaning agent is deionized water.

[0028] Beneficial effects: Deionized water has excellent electrical properties and chemical stability. When used as a cleaning agent, deionized water can react with dirt and impurities more effectively, improving the cleaning effect. At the same time, deionized water will not have unnecessary chemical reactions with substances on the surface of the cleaning object, avoiding secondary pollution.

[0029] Furthermore, it also includes a second acquisition component; the second acquisition component has the same structure as the first acquisition component; the second acquisition component is arranged at the air inlet of the machine room, and the first acquisition component is arranged at the air outlet of the machine room; the control module is also used to judge the dust content in the machine room based on the image information collected by the image sensors in the second acquisition component and the first acquisition component, and if the grayscale difference in the image information of the two exceeds a preset value, the early warning module is controlled to issue an early warning.

[0030] Beneficial effects: By setting up collection components at the air inlet and outlet of the computer room, comprehensive monitoring of the dust flow inside and outside the computer room can be achieved. The air inlet is the main way for dust to enter the computer room, while the air outlet reflects the discharge of dust inside the computer room. By comparing and analyzing the image information of the two, the purification effect and overall content of dust in the computer room can be judged more accurately. The control module can quantitatively evaluate the degree of dust accumulation in the computer room by comparing the changes in the grayscale value in the image information of the second collection component (air inlet) and the first collection component (air outlet). When the grayscale difference between the two exceeds the preset value, it means that the dust content in the computer room may be too high, and there is a potential safety hazard. At this time, the control module promptly controls the early warning module to issue an early warning, which can effectively avoid problems such as equipment failure or performance degradation caused by dust accumulation.

[0031] A rail transit machine room safety early warning method comprises the following steps: Step 1: Arrange the second collection component and the first collection component at each air inlet and outlet of the rail transit machine room; Step 2: using the shearing effect of the fluid to enrich the dust contained in the air passing into the second collection component and the first collection component; Step 3: Use the second acquisition component and the first acquisition component to emit light to the dust enriched by different components respectively, and collect image information after the light passes through the dust; Step 4: Analyze the image information and determine the dust content in the computer room based on the grayscale in the image information; if the grayscale value in the image information collected by the first acquisition component exceeds the preset value, perform an early warning process; if the grayscale difference between the image information collected by the first acquisition component and the second acquisition component exceeds the preset difference, perform an early warning process.

[0042] The following is further described in detail through specific implementation methods: Embodiment 1 is basically as attached Figure 1-Figure 6As shown: A rail transit machine room safety warning device, including: a first acquisition component and a control module; the first acquisition component includes a carrier 1; an active cavity 102 is provided in the carrier 1; an opening is provided on one side of the active cavity 102; a plurality of discs 103 are provided in the active cavity 102, and a preset distance is provided between the discs 103 and the discs 103 and the active cavity 102. The preset distance in this embodiment is twice the boundary layer thickness of the fluid, specifically twice the boundary layer thickness of air. A rotating shaft 4 is provided at the axis of the disc 103; the rotating shaft 4 passes through the axis of all the discs 103, and the rotating shaft 4 and the disc 103 are welded and fixed; a third channel 403 and a plurality of second channels 402 are provided in the rotating shaft 4, and the third channel 403 is arranged radially along the rotating shaft 4, and the third channel 403 is connected to the outside (outside the machine room), and the second channel 402 is used to introduce the fluid near the axis of the disc 103 into the third channel 403, as shown in the attached Figure 3 As shown, the second channel 402 is circumferentially opened on the rotating shaft 4, and the second channel 402 is located in the gap between the disks 103 and 103 and between the disks 103 and the active cavity 102; a driving member for driving the rotating shaft 4 to rotate is provided at one end of the rotating shaft 4, and the driving member is a motor 101 in this embodiment, and the driving member is electrically connected to the control module; a transparent adsorption layer 10 is provided at the disk 103 away from the axis, and the transparent adsorption layer 10 in this embodiment is made of transparent rubber.

[0043] The carrier 1 is also provided with a light-emitting component 9, an image acquisition module and an early warning module. The light-emitting component 9 is used to emit light to the transparent adsorption layer 10. Specifically, in this embodiment, the light-emitting component 9 is an incandescent lamp, the image acquisition module is used to obtain image information after the light passes through the transparent adsorption layer 10, and the early warning module is used to send early warning information; the control module is used to judge the dust pollution situation based on the image information and control the operation of the early warning module.

[0044] Specifically, the control module is used to judge the dust pollution situation based on the grayscale situation in the image information, that is, pollutants such as dust usually reduce the reflectivity of the surface, resulting in a decrease in the grayscale value of the corresponding area in the image (i.e., darkening). Therefore, the control module can judge the dust pollution situation (i.e., the dust content in the computer room) by analyzing the distribution of grayscale values ​​in each area of ​​the image. In order to accurately judge the degree of dust pollution, one or more grayscale thresholds need to be set. These thresholds can be determined based on the cleaning standards of the computer room, historical data, or experimental results. When the grayscale value of a certain area in the image information is lower than the set threshold, it can be considered that dust pollution exists.

[0045] As attached Figure 3As shown, a first cleaning component is also provided at the opening of the active cavity 102; the first cleaning component includes a three-way pipe 3; one outlet of the three-way pipe 3 is connected to a water storage tank 2, and the water storage tank 2 is filled with a cleaning agent, and the cleaning agent in this embodiment is deionized water. A first valve 201 is bolted to the connection between the water storage tank 2 and the three-way pipe 3, and the first valve 201 is electrically connected to the control module; the other outlet of the three-way pipe 3 is connected to the opening.

[0046] Specifically, when cleaning is required, the first valve 201 is driven to open by the control module, so that the deionized water in the water storage tank 2 passes through the first valve 201 and enters the three-way pipe 3, and finally flows to the opening and enters the active cavity 102, so as to rinse the disc 103.

[0047] The carrier 1 is also provided with a second cleaning assembly; the second cleaning assembly includes a plurality of functional chambers 7, the functional chambers 7 are arc-shaped, and in this embodiment, the functional chambers 7 are arc-shaped chambers with a central angle of 90 degrees; Figure 3 and attached Figure 4 As shown, the functional cavity 7 is respectively opened between the disk 103 and the disk 103 and between the disk 103 and the active cavity 102; an arc block 701 is arranged in the functional cavity 7. In this embodiment, the arc block 701 is consistent with the shape of the functional cavity 7, that is, the arc block 701 with a central angle of 90 degrees, and the fixed end of the arc block 701 (specifically, the arc block 701 has two ends, one end of which is the center of the circle when it deflects around the other end, and the end is the fixed end, the same below) is rotatably connected to the functional cavity 7; a baffle 706 and a receiving groove 707 are also arranged on the side of the functional cavity 7 close to the active cavity 102. In this embodiment, the baffle 706 and the receiving groove 707 are the same shape as the arc block 701, the baffle 706 and the receiving groove 707 are slidably matched, and the receiving groove 707 is connected with all the functional cavities 7, that is, as shown in the attached Figure 3 As shown, the accommodating groove 707 vertically penetrates and connects all the functional cavities 7; a first transmission assembly is arranged on the baffle 706, and the first transmission assembly is used to control the lifting and lowering of the baffle 706, and the first transmission assembly is electrically connected to the control module; a second transmission assembly is also arranged on the arc block 701, and the second transmission assembly is used to control the deflection of the arc block 701 based on the lifting and lowering of the baffle 706.

[0048] Specifically, the first transmission assembly includes a ring 6; the ring 6 is rotatably matched with the rotating shaft 4; a ring groove 601 is provided on the side of the ring 6 close to the rotating shaft 4, and a first channel 401 is also provided on the rotating shaft 4, and the first channel 401 is used to connect the third channel 403 with the ring groove 601; a protrusion 404 is welded and fixed at the connection point between the third channel 403 and the ring groove 601, and the protrusion 404 is used to reduce the cross-sectional area of ​​the third channel 403. In this embodiment, the protrusion 404 is in the shape of an annular structure; the ring groove 601 is also connected to the connecting pipe 5, and the other end of the connecting pipe 5 is connected to the sealing cavity 503; the sealing cavity 503 is opened in the carrier 1, and the sealing cavity 503 is located above the baffle 706; an elastic cushion layer 504 is bonded and fixed in the sealed cavity 503; the bottom of the sealed cavity 503 is connected with the accommodating groove 707, and a lifting shaft 705 is bonded and fixed at the bottom of the elastic cushion layer 504, and the lifting shaft 705 extends into the accommodating groove 707, and the lifting shaft 705 is welded and fixed to all baffles 706, and the lifting shaft 705 is slidably matched with the accommodating groove 707; the connecting pipe 5 is also connected with a branch pipe 501, and the branch pipe 501 is used to connect the connecting pipe 5 with the outside world (outside the machine room); a second valve 502 is also bolted to the connection point between the branch pipe 501 and the connecting pipe 5, and the second valve 502 is electrically connected to the control module.

[0049] The second transmission assembly includes a plurality of racks 704. In this example, the number of racks 704 is the same as the number of functional cavities 7. The back of the racks 704 is welded and fixed to the side of the lifting shaft 705. The racks 704 are respectively meshed with worm wheels 703. The turbines are respectively meshed with worms 702. The bottom of the worms 702 extends into the functional cavity 7, and the bottom of the worms 702 is welded and fixed to the fixed end of the arc block 701.

[0050] The specific implementation process is as follows: The air in the machine room is passed into the three-way pipe 3, and the control module starts the motor 101. After the air enters the active chamber 102, driven by the disc 103, the air makes a spiral centripetal motion between the discs 103 (boundary layer effect). The dust in the air adheres to the transparent adsorption layer 10 on the edge of the disc 103 during the movement, and then the air enters the third channel 403 along the second channel 402, and then is discharged to the outside through the third channel 403. In this process, the control module drives the light-emitting element 9 to work, so that the light emitted from the light-emitting element 9 passes through the transparent adsorption layer 10 in sequence and is captured by the image sensor 8. The control module analyzes the acquired image information, determines the dust content according to the grayscale, and then determines whether to start the early warning module. If the grayscale value is lower than the preset value, the early warning module is started, and the early warning module sends an early warning message to the staff; on the contrary, if the grayscale value is higher than the preset value, the early warning module is not started.

[0051] Then the control module drives the first valve 201 to open, and introduces deionized water into the active cavity 102. The disc 103 driven by the motor 101 rotates, and the disc 103 drives the deionized water to flush between the discs 103 and between the disc 103 and the active cavity 102. At the same time, the control module drives the second valve 502 to close, so that a closed space is formed in the connecting pipe 5. When air or deionized water is discharged from the third channel 403, the air pressure in the first channel 401 will decrease (Venturi effect), thereby acting on the elastic cushion layer 504, causing the elastic cushion layer 504 to deform and drive the lifting shaft 705 to move upward, thereby lifting the baffle 706, exposing the arc block 701 from the functional cavity 7, and under the action of the lifting shaft 705, the rack 704, the worm wheel 703, and the worm 702, the arc block 701 is deflected and offset from the functional cavity 7 to the surface of the disc 103, so that the dust on the surface of the disc 103 (mainly the transparent adsorption layer 10) is cleaned. After the preset time, the control module controls the second valve 502 to open, so that the air pressure in the connecting pipe 5 is restored to normal, the elastic cushion layer 504, the baffle 706, and the arc block 701 are reset, and the first valve 201 is closed to complete the cleaning.

[0052] In order to achieve continuous monitoring, the control module periodically controls the above process according to a preset duration, namely "detection-cleaning-detection-cleaning".

[0053] The only difference between Example 2 and Example 1 is that it also includes a second acquisition component; the second acquisition component has the same structure as the first acquisition component; the second acquisition component is arranged at the air inlet of the machine room, and the first acquisition component is arranged at the air outlet of the machine room; the control module is also used to judge the dust content in the machine room based on the image information collected by the image sensor 8 in the second acquisition component and the first acquisition component. If the grayscale difference in the image information of the two exceeds a preset value, the early warning module is controlled to issue an early warning, and the early warning information is sent to the staff through sound and light alarms, SMS notifications, email reminders, etc.

[0054] The specific implementation process is as follows: when the air from the air inlet enters the machine room after passing through the filters, fans and other equipment in the machine room, it first passes through the second collection component, that is, it enters the three-way pipe 3-active cavity 102-third channel 403-machine room in sequence. The dust content in the air entering the machine room is detected by the second collection component. At the same time, the disc 103 and the transparent adsorption layer 10 can also perform secondary purification on the air to reduce the dust content.

[0055] The control module compares the image information obtained by the image sensor 8 in the second acquisition component and the first acquisition component respectively. If the difference between the grayscale values ​​of the two is greater than the preset value, it means that a lot of dust has accumulated inside the machine room during the air circulation process, and the dust content in the machine room is too high. The control module sends a warning message to the staff to remind them to take timely measures for cleaning and maintenance.
