Description

Technical Field

[0001] This invention relates to the field of server hardware monitoring technology, specifically to a server monitoring device and monitoring method. Background Technology

[0002] In the digital age, servers play a crucial role. As the core equipment for data processing, the stability of server operation directly determines business continuity. In particular, standard rack servers, which are widely used in data centers, are the core hardware that carries computing, storage, and network services.

[0003] Chinese Patent Application No. 202111157763.3 discloses a server monitoring device and its control method, including a server chassis, a server housed within the chassis, a monitoring device, and a braking assembly. The braking assembly is located on the top of the server chassis, and the monitoring device is located inside the server chassis cavity. The monitoring device is connected to the braking assembly, which controls the monitoring device to rotate around the server within the server chassis cavity. A hinged cabinet door is attached to the front of the server chassis, and the cabinet door has a display screen for displaying monitoring data and a control panel for controlling the monitoring device. However, due to the extremely compact internal space of the server, especially the narrow spacing between servers within the cabinet, airflow between servers is severely restricted, potentially leading to localized overheating.

[0004] In addition, because servers need to continuously circulate air with the outside for heat dissipation, dust accumulates, especially between two adjacent servers where airflow is difficult, causing dust to stagnate and adhere to the server surface, affecting heat dissipation. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a server monitoring device and monitoring method that can achieve precise heat dissipation of the channel between servers, prevent local overheating, and effectively deal with the dust adhering to the surface of the channel between the upper and lower servers, thereby improving heat dissipation efficiency and effectively solving the problems in the background art.

[0006] To achieve the above objectives, the present invention discloses the following technical solution: a server monitoring device, comprising: The cabinet has servers arranged in layers inside. The front side of the cabinet has a front door panel, and the rear side has a rear door panel. The rear door panel is equipped with an exhaust fan. The inner walls of both the front and rear sides of the cabinet are equipped with electric sliding rails. The front monitoring component is mounted on an electric slide rail on the front side. It includes an extension mechanism with an extension seat. A front camera is embedded in the center of the extension seat. A dual-axis motor is installed inside the extension seat. Electric telescopic rods are mounted on the output shafts on both sides of the dual-axis motor via mounting seats. Mounting brackets are installed at the extension ends of the electric telescopic rods on both sides. A hollow shaft is rotatably connected between the mounting brackets on both sides. A cleaning part is provided on the side of the hollow shaft. A rotary motor that is drivenly connected to the hollow shaft is provided at the end of the mounting bracket. An air hole is opened on the side of the hollow shaft. The front monitoring component also includes a mounting slot, which is located on the side of the extension seat. An air intake fan is provided at the end of the mounting slot, and an air pipe communicating with the mounting slot is provided on the extension seat. The end of the air pipe is rotatably connected to the end of the hollow shaft.

[0007] Preferably, it also includes a rear monitoring component, which is located on the rear electric slide rail and also includes an extension mechanism with an extension seat. The extension seat located on the rear side has a slot seat, in which a rear camera is embedded. Filter plates are provided in the side slots on both sides of the slot seat, and an exhaust fan is provided on the side of the slot seat away from the filter plates.

[0008] Preferably, the filter plate is equipped with a gas flow rate sensor, the exhaust fan is used to generate negative pressure inside the slot, a filter element is provided inside the slot between the filter plate and the exhaust fan, and a temperature sensor is provided inside the slot.

[0009] Preferably, it also includes an air intake assembly, which includes an air intake slot located on the front door panel. The air intake slot has rotating shafts evenly distributed on its inner side, and each rotating shaft has an air guide plate at its inner end.

[0010] Preferably, each rotating shaft has a gear at its outer end, and the gear is externally meshed with a rack. The rack and the side wall of the air intake groove are connected by a damped sliding connection.

[0011] Preferably, the rack has an electric push rod on its side, the telescopic end of the electric push rod has a retainer, and the outer side of the air inlet groove has a filter screen.

[0012] Preferably, the extension mechanism includes a guide rail, which is disposed on the sliding part of the electric slide rail. A bidirectional screw is rotatably connected inside the guide rail. The two sides of the bidirectional screw are provided with threads in opposite directions. A slide seat is threaded onto both sides of the bidirectional screw. A connecting rod is hinged to the slide seat on both sides. The opposite ends of the connecting rods on both sides are respectively hinged to the two sides of the extension seat. A drive motor that is transmitted and connected to the end of the bidirectional screw is embedded in the guide rail.

[0013] This invention also discloses a monitoring method for a server monitoring device, comprising the following steps: S1. When the server is in normal working condition, start the exhaust fan to allow external airflow to enter the cabinet through the air intake slot, forming a basic heat dissipation cycle; the front and rear monitoring components ( , ) move vertically under the drive of the corresponding electric slide rails to perform regular inspections of the layered servers; S2. During the inspection, the temperature sensor monitors the airflow temperature in the channel between adjacent servers in real time. If the airflow temperature exceeds the set threshold, it is determined that the corresponding channel has local high temperature. The dual-axis motor is controlled to drive the hollow shaft to rotate and align with the high temperature channel. The electric telescopic rod pushes the hollow shaft to extend into the front port of the channel. At the same time, the intake fan starts and sprays the external low temperature airflow into the channel through the air hole on the side of the hollow shaft for precise heat dissipation. S3. During the inspection, the rear camera detects the amount of dust attached to the lens. If it exceeds the set value, the hollow shaft is adjusted to be horizontal and extended into the corresponding channel. The fan starts to spray air into the channel. At the same time, the dual-axis motor drives the hollow shaft to swing up and down. The rotating motor drives the hollow shaft to rotate, so that the cleaning part brushes away the dust on the server surface. The exhaust fan sucks the dust into the filter in the slot for collection. S4. During the cleaning process, if the gas flow rate sensor on the filter plate detects that the flow rate is lower than the set threshold, the hollow shaft is controlled to extend horizontally to the outside of the filter plate so that the cleaning part contacts the surface of the filter plate. The rotating motor drives the hollow shaft to rotate to clean the filter plate, while the fan keeps working to suck the fallen dust into the filter element. S5. During heat dissipation and monitoring, the front guide rail is moved to the position corresponding to the card holder by the electric slide rail. The electric push rod pushes the card holder to engage with the guide rail. When the guide rail moves up and down, it drives all the air guide plates to swing synchronously through the rack and gear to adjust the air intake angle. S6. During the monitoring process, the temperature, image and airflow data collected are uploaded to the external control terminal in real time through the communication control module, and the corresponding cooling, dust removal and airflow adjustment operations are automatically triggered based on the data.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When the temperature sensor detects that the airflow temperature in the channel between adjacent servers exceeds a set threshold, the system can automatically control the dual-axis motor and electric telescopic rod in the front monitoring component to adjust the hollow shaft and extend it into the front port of the corresponding high-temperature channel. At the same time, the intake fan is started, and the external low-temperature airflow is pressurized and directionally sprayed into the channel through the air holes on the side of the hollow shaft, directly impacting the server surface, breaking the hot air layer trapped in the narrow channel, enhancing local convection heat dissipation, achieving precise cooling of hot spots in narrow spaces, and effectively preventing local overheating of servers caused by poor airflow.

[0015] 2. When the rear camera detects an increase in dust adhering to the lens, the system determines that there is a lot of dust on the server surface in the corresponding channel. It then controls the front monitoring component to make the hollow shaft carry the cleaning part into the channel. The dual-axis motor drives it to swing up and down, so that the cleaning part alternately contacts the upper and lower walls of the channel. At the same time, the rotating motor drives the hollow shaft to rotate, and the airflow from the inlet fan brushes off the dust. The brushed-off dust is sucked into the slot by the negative pressure generated by the exhaust fan and collected by the filter element. This achieves a fully enclosed dust removal process, avoids secondary dust diffusion, and significantly improves the cleanliness of the server surface and heat dissipation efficiency.

[0016] 3. During operation, the electric slide rail drives the front guide rail to move to the position corresponding to the card holder. The electric push rod pushes the card holder to engage with the guide rail. Subsequently, the up and down movement of the guide rail drives all the air guide plates to swing synchronously through the rack and pinion mechanism, thereby dynamically adjusting the angle of the air intake. This mechanism can flexibly set the air guide direction according to the layered layout of the server, so that the cold air is delivered more evenly into the gaps between each layer of the server, improving the overall heat dissipation airflow organization and further avoiding local temperature rise caused by uneven air intake.

[0019] 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. Example 1

[0020] Please see Figure 1-12 This embodiment provides a technical solution: a server monitoring device, including a cabinet 1, in which servers 101 are arranged in layers, a front door panel 102 is provided on the front side of the cabinet 1, a rear door panel 103 is provided on the rear side of the cabinet 1, an exhaust fan 104 is provided on the rear door panel 103, and electric slide rails 105 are provided on the inner walls of both the front and rear sides of the cabinet 1.

[0021] Specifically, the server 101 is arranged in layers inside the cabinet 1 with gaps between adjacent servers 101. The airflow generated by the exhaust fan 104 is directed towards the outside of the cabinet 1. In cooperation with the air intake component 4, it achieves heat dissipation inside the cabinet 1. The electric slide rails 105 on the front and rear sides are used to drive the front monitoring component 2 and the rear monitoring component 3 to move in the vertical direction, respectively.

[0022] The cabinet 1 is also equipped with a communication control module, which is used to communicate remotely with external terminals and remotely control the electric slide rail 105, drive motor 111, front camera 201, rear camera 302, dual-axis motor 202, electric telescopic rod 204, rotation motor 208, intake fan 210, exhaust fan 304 and electric push rod 406 to perform actions.

[0023] It also includes a front monitoring component 2, which is mounted on the electric slide rail 105 on the front side. The front monitoring component 2 includes an extension mechanism with an extension seat 110. A front camera 201 is embedded in the middle of the extension seat 110. A dual-axis motor 202 is provided inside the extension seat 110. Electric telescopic rods 204 are provided on both sides of the output shaft of the dual-axis motor 202 through mounting seats 203. Mounting brackets 205 are provided at the telescopic ends of the electric telescopic rods 204 on both sides. A hollow shaft 206 is rotatably connected between the mounting brackets 205 on both sides. A rotating motor 208 is provided at the end of the mounting bracket 205 and is connected to the hollow shaft 206. An air hole is provided on the side of the hollow shaft 206.

[0024] Specifically, the front camera 201 is used to monitor the operating status of the front side of the server 101, the extension mechanism is used to drive the extension seat 110 to move horizontally and linearly, thereby adjusting the distance between the front camera 201 and the server 101, and the dual-axis motor 202 is used to drive the mounting seats 203 on both sides and the electric telescopic rod 204 to rotate synchronously, thereby driving the hollow shaft 206 to rotate around the axis of the dual-axis motor 202 through the mounting bracket 205, so as to adjust the position of the hollow shaft 206. In the initial state, the hollow shaft 206 is located below the extension seat 110 to prevent it from blocking the view of the front camera 201.

[0025] The front monitoring component 2 also includes a mounting slot 209, which is located on the side of the extension seat 110. The end of the mounting slot 209 is provided with an intake fan 210. The extension seat 110 is provided with an air pipe 211 that communicates with the mounting slot 209. The end of the air pipe 211 is rotatably connected to the end of the hollow shaft 206.

[0026] Specifically, the fan 210 blows air into the mounting slot 209 to form a high-pressure airflow, which enters the hollow shaft 206 through the air pipe 211 and is finally discharged through the air hole on the side of the hollow shaft 206. The rotatable connection between the air pipe 211 and the hollow shaft 206 prevents the air pipe 211 from being entangled.

[0027] It also includes a rear monitoring component 3, which is located on the electric slide rail 105 on the rear side. It also includes an extension mechanism with an extension seat 110. The extension seat 110 on the rear side is provided with a slot 301. A rear camera 302 is embedded in the middle of the slot 301. Filter plates 303 are provided in the side slots on both sides of the slot 301. A fan 304 is provided on the side of the slot 301 away from the filter plates 303. The fan 304 is used to generate negative pressure inside the slot 301. A temperature sensor is provided inside the slot 301.

[0028] Specifically, the rear extension mechanism drives the rear extension seat 110, which in turn drives the rear monitoring component 3 to move horizontally in a straight line. The rear camera 302 is used to monitor the operating status of the rear of the server 101 and the status of the cables.

[0029] It also includes an air intake assembly 4, which includes an air intake slot 401. The air intake slot 401 is located on the front door panel 102. A filter screen 408 is provided on the outer side of the air intake slot 401. Rotating shafts 402 are evenly provided on the inner side of the air intake slot 401. Each rotating shaft 402 has an air guide plate 403 at its inner end.

[0030] Specifically, in the initial state, the air guide plate 403 is in a horizontal state, which is used to ensure that the airflow enters the cabinet 1 evenly, and the filter screen 408 is used to filter the impurities contained in the incoming airflow.

[0031] Each rotating shaft 402 has a gear 404 at its outer end. The gear 404 is externally meshed with a rack 405. The rack 405 is damped and slidably connected to the side wall of the air intake groove 401. An electric push rod 406 is provided on the side of the rack 405. The telescopic end of the electric push rod 406 is provided with a retainer 407.

[0032] Specifically, by driving the rack 405 to move up and down linearly, the gears 404 are rotated, causing the air guide plates 403 to rotate synchronously, thereby adjusting the air guide angle of the air guide plates 403. After the front guide rail 106 moves to the position corresponding to the card holder 407, the extension of the electric push rod 406 causes the card holder 407 to engage with the guide rail 106. The up and down linear motion of the guide rail 106 can then drive the rack 405 to move up and down linearly, thereby achieving the angle adjustment of the air guide plate 403.

[0033] The extension mechanism includes a guide rail 106, which is mounted on the sliding part of the electric slide rail 105. A bidirectional screw 107 is rotatably connected inside the guide rail 106. The two sides of the bidirectional screw 107 are provided with threads in opposite directions. Both sides of the bidirectional screw 107 are threadedly fitted with slide blocks 108. Both sides of the slide blocks 108 are hinged with connecting rods 109. The opposite ends of the connecting rods 109 are respectively hinged to the two sides of the extension seat 110. A drive motor 111 that is driven and connected to the end of the bidirectional screw 107 is embedded in the guide rail 106.

[0034] Specifically, the drive motor 111 drives the bidirectional screw 107 to rotate. Since the slide 108 is slidably connected to the guide rail 106, the two slides 108 can be brought together or separated. Then, the extension seat 110 can be extended and retracted through the connecting rod 109, so that the distance between the front camera 201 and the rear camera 302 and the server 101 can be adjusted respectively.

[0035] During use, both the front door panel 102 and the rear door panel 103 are closed. When the server 101 is in normal working condition, the exhaust fan 104 on the rear door panel 103 is activated. The exhaust fan 104 exhausts the hot air inside the cabinet 1 to the outside. The cooler external air is filtered by the filter screen 408 under the action of pressure difference and flows through the air intake slot 401. Guided by the air guide plate 403 in its initial horizontal state, it enters the front space of the cabinet 1. The airflow then passes through the upper and lower layered servers 101, absorbs the heat generated by the operation of the servers 101, and becomes hot air before flowing to the rear of the cabinet 1, and is finally exhausted by the exhaust fan 104. Outside the cabinet 1, a basic heat dissipation circulation is formed. At the same time, the front electric slide rail 105 is used to move the front guide rail 106 to the position corresponding to the card holder 407. The electric push rod 406 extends, so that the card holder 407 and the guide rail 106 are engaged. Then, the front electric slide rail 105 drives the guide rail 106 to move up and down back and forth. In turn, the card holder 407 and the electric push rod 406 drive the rack 405 to move up and down, so that each air guide plate 403 swings up and down back and forth, thereby adjusting the angle of the air intake airflow, making the air intake more uniform, and setting a specified air intake angle according to the specific distribution and number of layers of the server 101.

[0036] During the heat dissipation process, the front camera 201 and the rear camera 302 perform periodic inspections of the server 101. During the inspection, the electric push rod 406 retracts, causing the card holder 407 to disengage from the front guide rail 106. Driven by the electric slide rails 105 on the front and rear sides respectively, the front camera 201 and the rear camera 302 move vertically along the inner wall of the cabinet 1 to inspect the front and rear status of each layer of the server 101. At the same time, the extension mechanisms on the front and rear sides are activated to adjust the positions of the front camera 201 and the rear camera 302 respectively, so that the front camera 201 and the rear camera 302 are close to the front and rear ends of the server 101 respectively. The front camera 201 and the rear camera 302 capture visual information such as the status indicator lights, labels and rear cable connections on the front and rear panels of the server 101, and feed it back to the external control terminal through the communication control module.

[0037] During the inspection process, the exhaust fan 304 inside the slot 301 of the rear monitoring component 3 continuously operates, generating a stable negative pressure within the slot 301. This draws hot air from the narrow passage between two adjacent servers 101 through the filter plate 303 into the slot 301. A temperature sensor located inside the slot 301 monitors the temperature of the incoming air in real time. When the temperature sensor detects that the temperature of the passing air exceeds a set temperature threshold, it determines that a localized high temperature has occurred in the passage between the two adjacent servers 101. At this point, the front camera 201 is moved to the front end of the high-temperature passage, and the dual-axis motor 202 is activated, driving the electric telescopic rods 204 on both sides and the mounting bracket 205 to rotate, causing the hollow shaft 20... 6. Rotate from the initial storage position to align with the front port of the high-temperature channel. At this time, the hollow shaft 206 corresponds to the front camera 201, and the air hole on the side of the hollow shaft 206 corresponds to the front port of the high-temperature channel. When the exhaust fan 304 is working, start the intake fan 210. The intake fan 210 pressurizes the low-temperature airflow from the intake component 4 and guides it into the hollow shaft 206 through the air pipe 211. It is then sprayed into the high-temperature channel through the air hole. The sprayed low-temperature airflow directly impacts the surface of the server 101, that is, the upper and lower walls of the high-temperature channel, thereby breaking the hot air layer trapped between two adjacent servers 101, enhancing the forced convection heat dissipation effect in the local area, and achieving local high temperature cooling.

[0038] Example 2 However, due to the low airflow velocity between two adjacent servers 101, dust and impurities tend to accumulate in the channel between the two adjacent servers 101, affecting the heat dissipation of the servers 101. Therefore, the following improvements are made: The hollow shaft 206 has a cleaning part 207 on its side, which is preferably a soft brush.

[0039] A filter element is provided inside the trough 301 between the filter plate 303 and the exhaust fan 304. The filter element is used to collect dust and impurities sucked into the trough 301.

[0040] During operation, while the rear monitoring component 3 is performing its inspection, if the rear camera 302 detects a significant amount of dust on its lens as it passes through a passage between adjacent servers 101, it determines that the surface of the server 101 corresponding to that passage is heavily dusty. At this point, the front camera 201 is positioned at the front end of the corresponding passage, and the dual-axis motor 202 adjusts the hollow shaft 206 to a horizontal position corresponding to the front camera 201, with the vents facing inwards. Then, the electric telescopic rod 204 is activated to extend, allowing the... The hollow shaft 206 feeds into the channel. At the same time, the intake fan 210 is started, and high-pressure airflow is injected into the hollow shaft 206 through the air pipe 211 and sprayed into the channel through the air hole. The dual-axis motor 202 drives the hollow shaft 206 to swing up and down, so that the cleaning part 207 contacts the upper and lower walls of the channel respectively, and the air hole faces the upper and lower walls of the channel respectively. At the same time, the rotary motor 208 drives the hollow shaft 206 to rotate back and forth, so as to realize the reciprocating rotation of the cleaning part 207, so as to brush off the dust and impurities attached to the surface of the server 101.

[0041] As dust and impurities are brushed off, the exhaust fan 304 is activated. The negative pressure generated in the slot 301 draws the brushed-off dust and impurities into the slot 301 and collects them on the filter element, preventing the brushed-off dust and impurities from spreading around inside the cabinet 1. The dust and impurities attached to the rear camera 302 are fed back to the external terminal through the communication control module, reminding the staff to clean the lens of the rear camera 302.

[0042] In addition, during the cleaning of dust and impurities on the surface of server 101, the filter holes on filter plate 303 are prone to clogging, resulting in a poorer collection effect of brushed-off dust and impurities, and some dust and impurities are prone to drifting into cabinet 1. Therefore, the following improvements are made: A gas flow rate sensor is provided on the filter plate 303. The gas flow rate sensor is used to detect the flow rate of the airflow entering the slot 301 through the filter plate 303. During use, when the gas flow rate sensor detects that the gas flow rate through the filter plate 303 is less than the set flow rate threshold, it actively determines that the filter plate 303 is blocked. At this time, when the blockage of the filter plate 303 is detected during dust removal on the surface of the server 101, the hollow shaft 206 stops swinging up and down and rotating and remains horizontal. By extending the electric telescopic rod 204, the hollow shaft 206 is brought close to the outer side of the filter plate 303 at the other end. At this time, the cleaning part 207 is in contact with the outer surface of the filter plate 303. Then, the rotating motor 208 is started to drive the hollow shaft 206 to rotate. At the same time, the exhaust fan 304 is started to put the slot 301 into a negative pressure state. The rotation of the cleaning part 207 removes the dust and impurities blocked on the filter plate 303. At the same time, the negative pressure in the slot 301 adsorbs the dust and impurities onto the filter element, thereby realizing the cleaning of the filter plate 303 and the collection of falling dust and impurities.

[0043] Example 3 This embodiment also discloses a monitoring method for a server monitoring device, including the following steps: S1. When the server 101 is in normal working condition, the exhaust fan 104 is turned on so that the external airflow enters the cabinet 1 through the air intake slot 401 to form a basic heat dissipation cycle; the front and rear monitoring components 2 and 3 move vertically under the drive of the corresponding electric slide rails 105 to perform regular inspections of the layered server 101. Specifically, in the basic heat dissipation cycle, the start / stop and speed of the exhaust fan 104 can be adjusted by PID according to the average temperature inside the cabinet 1 to save energy and maintain a stable negative pressure. The movement speed of the electric slide rails 105 of the front and rear monitoring components 2 and 3 can be set to stepped or multi-segment to adapt to the inspection needs of different density server layers. The inspection cycle can be set remotely through an external terminal and supports automatic shortening of the cycle when a high temperature warning is issued. Image data is compressed and uploaded in real time, and image enhancement and fault marking can be performed on the terminal.

[0044] S2. During the inspection, the temperature sensor monitors the airflow temperature of the channel between adjacent servers 101 in real time. If the airflow temperature exceeds the set threshold, it is determined that the corresponding channel has local high temperature. The dual-axis motor 202 is controlled to drive the hollow shaft 206 to rotate and align with the high temperature channel. The electric telescopic rod 204 pushes the hollow shaft 206 to extend into the front port of the channel. At the same time, the intake fan 210 is started to spray the external low temperature airflow into the channel through the air hole on the side of the hollow shaft 206 for precise heat dissipation. Specifically, the temperature threshold setting can be dynamically adjusted based on the server 101 model, ambient temperature, and historical operating data. During the jet cooling process, the speed of the intake fan 210 and the jet duration can be proportionally adjusted according to the temperature difference value to ensure heat dissipation efficiency while avoiding overcooling. The depth of the hollow shaft 206 extending into the channel can be adaptively adjusted according to the channel width to avoid collision with the surface of the server 101. The system supports recording the location, temperature, and processing log of each high-temperature event.

[0045] S3. During the inspection, the rear camera 302 detects the amount of dust attached to the lens. If it exceeds the set value, the hollow shaft 206 is adjusted to be horizontal and extended into the corresponding channel. The inlet fan 210 starts to spray air into the channel. At the same time, the dual-axis motor 202 drives the hollow shaft 206 to swing up and down, and the rotation motor 208 drives the hollow shaft 206 to rotate. The cleaning part 207 brushes away the dust on the surface of the server 101, and the exhaust fan 304 sucks the dust into the filter element in the slot 301 for collection. Specifically, dust detection can be achieved by performing grayscale analysis or edge sharpness calculation on images captured by the rear camera 302. The threshold can be set according to the cleanliness level of the computer room. During the cleaning process, the oscillation frequency and rotation speed of the hollow shaft 206 can be coupled and controlled with the airflow pressure of the inlet fan 210 to improve the dust removal efficiency. The filter element is designed to be detachable, and the system can remind you to replace the filter element based on the change in the current of the exhaust fan 304 or the working time.

[0046] S4. During the cleaning process, if the gas flow rate sensor on the filter plate 303 detects that the flow rate is lower than the set threshold, the hollow shaft 206 is controlled to extend horizontally to the outside of the filter plate 303, so that the cleaning part 207 contacts the surface of the filter plate 303. The rotating motor 208 drives the hollow shaft 206 to rotate to clean the filter plate 303. At the same time, the fan 304 keeps working to suck the fallen dust into the filter element. Specifically, the gas flow rate sensor can be either hot-wire or differential pressure type. The set threshold can be dynamically calibrated based on the reference flow rate of the filter plate 303 in its initial clean state. When cleaning the filter plate 303, the rotation speed and contact pressure of the hollow shaft 206 are adjustable to avoid damaging the surface of the filter plate 303. After cleaning, the system automatically verifies the flow rate. If it still does not recover, an alarm is issued to prompt manual intervention. The degree of filter element blockage can also be indirectly monitored by changes in airflow resistance.

[0047] S5. During heat dissipation and monitoring, the electric slide rail 105 moves the front guide rail 106 to the position corresponding to the card holder 407. The electric push rod 406 pushes the card holder 407 to engage with the guide rail 106. When the guide rail 106 moves up and down, the rack 405 and gear 404 drive all the air guide plates 403 to swing synchronously to adjust the air intake angle. Specifically, the angle adjustment of the air guide plate 403 can be controlled by feedback based on the temperature distribution data of each server 101 channel to achieve intelligent airflow. The snap-fit ​​design of the guide rail 106 and the card holder 407 is equipped with a position sensor to ensure accurate docking. The damping sliding connection of the rack 405 can prevent the air guide plate 403 from swinging on its own and maintain angle stability. The system supports saving multiple airflow modes to adapt to different server layouts.

[0048] S6. During the monitoring process, the temperature, image and airflow data collected are uploaded to the external control terminal in real time through the communication control module, and the corresponding cooling, dust removal and air guiding adjustment operations are automatically triggered based on the data.

[0049] Specifically, the communication control module supports wired communication protocols such as Ethernet or wireless protocols such as Wi-Fi and 5G. Data upload can be done via polling or interrupt triggering. The external control terminal has a graphical interface that can display data from each sensor, device status, and alarm information in real time. It also supports manual remote control of any actuator. All operation records, alarm events, and data trends are stored locally or in the cloud and can be exported and analyzed to provide a basis for operation and maintenance decisions.
