Description

Technical Field

[0001] The present invention relates to the technical field of server cabinet monitoring, and specifically to a monitoring device and method for abnormal status indication in a server cabinet. Background Art

[0002] As a facility that runs 24 hours a day without interruption, the server cabinets in a data center are densely packed with internal equipment and have intricate electronic components. A large amount of dust will accumulate during long-term operation. This dust not only accumulates on the surface of electronic devices, affecting heat dissipation, causing the device temperature to rise and performance to decline, but may also cause short-circuit and static electricity problems. The data center also has strict requirements for the environment. For example, for every 10-degree Celsius increase in the temperature inside the cabinet, the lifespan of components is reduced by 30% - 50%, affecting the reliability and performance of the devices.

[0003] When the existing server cabinets in a data center monitor abnormal dust inside the cabinet, it is only by visual inspection of the staff. The internal lighting of the cabinet can only see the outermost part, and it is difficult to monitor the corners and crannies. The inspection accuracy is not high, and the equipment cannot be maintained in a timely manner. At the same time, although a temperature detection system is set inside the cabinet and a corresponding heat dissipation system is equipped, most of such temperature sensors are fixedly installed in conventional positions. Since the internal temperature of the cabinet is uneven during operation, the measurement results will cause errors, resulting in untimely heat dissipation. As a result, the service life of some components inside the cabinet is reduced under high-temperature environments. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a monitoring device and method for abnormal status indication in a server cabinet, which solves the problems of poor dust monitoring accuracy in the server cabinet and heat accumulation at uneven temperature areas inside the cabinet.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A monitoring device for abnormal status indication in a server cabinet, comprising: A dust detection module, which is arranged on the inner side wall of the cabinet body. The dust detection module includes a laser emitter, a light sensor, and multiple reflectors. The multiple reflectors are circumferentially arranged inside the cabinet body from top to bottom. The multiple reflectors form a laser light refraction path from top to bottom, and one end of the refraction path is the emission starting end and the other end is the reception ending end. The laser emitter is arranged at the emission starting end of the laser refraction path of the multiple reflectors, and the light sensor is arranged at the reception ending end of the laser refraction path of the multiple reflectors; A temperature detection module, and there are multiple temperature detection modules, all of which are arranged on the inner components of the cabinet body.

[0006] Preferably, the light sensor is connected to the monitoring platform of the server cabinet through a signal line.

[0007] Preferably, a connecting rod is fixed to the non-mirror side of each of the reflectors, a spherical ball is fixed to the other end of the connecting rod, the spherical balls are all arranged in the limiting grooves, the limiting grooves are all arranged inside the base, a moving groove communicating with the limiting groove is arranged inside the base, a positioning wedge is slidably arranged in the moving groove, a threaded rod is rotatably connected to one side of the positioning wedge, the threaded rods are all threadedly connected through the base, a handle is fixed to the end of the threaded rod away from the positioning wedge, and one side of the positioning wedge is arranged as an inclined surface and the inclined surface abuts against the spherical ball.

[0008] Preferably, a magnetic attraction seat is fixed to the side of each base away from the spherical ball, and the magnetic attraction seats are all of strong magnetism and magnetically attracted inside the cabinet body.

[0009] Preferably, each temperature detection module includes a housing, an air outlet and an axial flow fan. The housing is a hollow metal cavity. The two ends of the housing are respectively connected to the air outlet and the axial flow fan. A bracket is arranged on one side of the housing close to the air outlet, a contact switch is arranged on the upper part of the bracket, and a bimetallic strip is arranged on the side of the housing close to the axial flow fan.

[0010] Preferably, the bimetallic strip includes a copper sheet and an iron sheet, the copper sheet and the iron sheet are fixedly attached to each other, the copper sheet is arranged on the side of the air outlet end close to the axial flow fan, the tops of the copper sheet and the iron sheet are directly opposite to the induction part of the contact switch, and the contact switch is connected in parallel with the heat dissipation mechanism of the cabinet body.

[0011] Preferably, the obtuse angle formed by the connecting rod and the end of the base is between 90 and 160 degrees.

[0012] Preferably, a method for prompting abnormal status in a server cabinet. The device used for prompting abnormal status in the server cabinet is the monitoring device for prompting abnormal status in the server cabinet described above, and includes the following steps: S1. Dust detection: a. Laser path debugging: Install the base at the part in the cabinet body that needs dust monitoring, and then adjust the angle of the reflector on the base starting from the laser emission starting end, so that the reflectors in the cabinet body form a laser path that reflects a beam of light from top to bottom. At this time, turn the threaded rod through the handle to make the positioning wedge slide in the moving groove. The inclined surface on one side of the positioning wedge presses the spherical ball, and the spherical ball is fixed in the limiting groove, and the reflector is fixed, and the laser path debugging is completed; b. Dust actual situation detection: The laser emitter emits laser to the first reflector on the laser path, and the light is reflected from the last reflector on the laser path in turn and irradiates on the light sensor. The light sensor converts the data through the encoder and then transmits it to the monitoring platform through the signal line, and then infers the dust concentration through the light intensity of the light sensor pipeline; S2. Temperature Detection: Place the temperature detection module at a location inside the cabinet body where temperature measurement is difficult. The axial flow fan extracts the surrounding temperature into the shell. The temperature causes the iron sheet and the copper sheet to thermally expand. After the copper sheet expands, the bimetallic strip bends towards the contact switch. When the temperature exceeds the normal operating temperature inside the server, the bimetallic strip triggers the contact switch. At this time, the contact switch closes, causing the parallel heat dissipation mechanism to operate and cooling the inside of the cabinet body.

[0013] The present invention provides a monitoring device and method for abnormal status indication inside a server cabinet. It has the following beneficial effects: 1. In the present invention, the angle of the reflector on the base is adjusted starting from the laser emission starting end, so that the reflectors inside the cabinet body form a laser path that can reflect a beam of light from top to bottom. At this time, turn the threaded rod with the handle to make the positioning wedge slide in the moving groove. The inclined surface on one side of the positioning wedge presses the ball, and the ball is fixed in the limiting groove, fixing the reflector, and the laser path debugging is completed. The laser emitter emits laser light onto the first reflector on the laser path, and the light is reflected from the last reflector on the laser path in sequence along the laser path and irradiates onto the light sensor. The light sensor converts the data through the encoder and transmits it to the monitoring platform through the signal line. Then, the dust concentration is inferred from the light intensity of the light sensor pipeline. After dust accumulates on the reflector, the amount of light reflection will decrease. Multiple reflectors are arranged at different positions inside the cabinet body. As long as the dust concentration on the reflector is high, the light on the light sensor will be weak. Then, the staff on the monitoring platform need to perform dust removal operations on the inside of the cabinet after seeing it. The reflector can be flexibly installed at different positions inside the cabinet body, which can comprehensively monitor the dust concentration of the cabinet body. At the same time, the dust concentration can be accurately and intuitively seen through the data, and the cabinet can be maintained in time to avoid affecting the operation of the data server.

[0014] 2. In the present invention, the temperature detection module is placed at a location inside the cabinet body where temperature measurement is difficult. The axial flow fan extracts the surrounding temperature into the shell. The temperature causes the iron sheet and the copper sheet to thermally expand. After the copper sheet expands, the bimetallic strip bends towards the contact switch. When the temperature exceeds the normal operating temperature inside the server, the bimetallic strip triggers the contact switch. At this time, the contact switch closes, causing the parallel heat dissipation mechanism to operate and cooling the inside of the cabinet body. A temperature detection module can be installed in the corners and places with uneven temperature inside the cabinet body, which can automatically control the temperature and accurately ensure the temperature monitoring of the areas where heat dissipation is difficult inside the cabinet. The cabinet body will not stop heat dissipation because the temperature in the conventional positions reaches the set value, realizing accurate temperature measurement and timely heat dissipation of the cabinet, and ensuring the service life of the components inside the cabinet.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment 1:

[0019] As Figures 1-6 shown, the embodiment of the present invention provides a monitoring device for abnormal status prompt in a server cabinet, including: Dust detection module 22 is arranged on the inner side wall of the cabinet body 1. The dust detection module 22 includes a laser emitter 5, a light sensor 4 and multiple reflectors 3. The multiple reflectors 3 are circumferentially arranged inside the cabinet body 1 from top to bottom. The multiple reflectors 3 form a laser light refraction path from top to bottom, and one end of the refraction path is the emission start end and the other end is the reception end. The laser emitter 5 is arranged at the emission start end of the laser refraction path of the multiple reflectors 3, and the light sensor 4 is arranged at the reception end of the laser refraction path of the multiple reflectors 3. The laser refraction path can be arranged at any position inside the cabinet body 1. As long as the dust concentration needs to be monitored, the corresponding reflector 3 can be arranged inside the cabinet body 1. The angle of the reflector 3 can be set according to the laser path. The upward reflector 3 can accumulate dust and refract the laser, and the downward reflector 3 is mainly responsible for refracting the light. The light sensor 4 can use a BH1750 photometric sensor. In actual use, an optical camera can also be arranged on the side of the reception end of the laser path. The smaller the laser captured by the camera, the more dust accumulation is proved. In this technical solution, the lower the laser intensity received by the light sensor 4, the more dust accumulation is proved; Temperature detection modules 2 are multiple and are all arranged on the inner components of the cabinet body 1. The temperature detection modules 2 are arranged at the dead corners in the cabinet body 1 that need to be monitored and at the temperature imbalance positions in the cabinet body 1. If it is not known where the temperature imbalance position in the cabinet body 1 is, the position of the temperature detection module 2 can be changed to obtain the temperature anomaly position. After determining the temperature anomaly position, the temperature detection module 2 is placed for a long time to facilitate the heat dissipation of the cabinet body 1.

[0020] The light sensor 4 is connected to the monitoring platform of the server cabinet through a signal line. The monitoring platform directly obtains the light intensity data, and there is no need for the staff to check the dust situation inside the cabinet body 1 separately. The dust anomaly inside the cabinet body 1 can be directly monitored online and remotely.

[0021] A connecting rod 8 is fixed to the non-mirror side of each mirror 3. The other end of the connecting rod 8 is fixed with a spherical ball 9. The spherical balls 9 are all arranged in the limiting groove 13. The limiting grooves 13 are all arranged inside the base 6. A moving groove 12 communicating with the limiting groove 13 is arranged inside the base 6. A positioning wedge 11 is slidably arranged in the moving groove 12. One side of the positioning wedge 11 is rotatably connected with a threaded rod 10. The threaded rods 10 are all threadedly connected through the base 6. One end of the threaded rod 10 away from the positioning wedge 11 is fixed with a handle 7. One side of the positioning wedge 11 is provided with an inclined surface that abuts against the spherical ball 9. The base 6 is installed at the part in the cabinet body 1 that needs dust monitoring. Then, the angle of the mirror 3 on the base 6 is adjusted starting from the laser emission starting end, so that the mirrors 3 in the cabinet body 1 form a laser path that can reflect a beam of light from top to bottom. At this time, the threaded rod 10 is rotated by the handle 7 to make the positioning wedge 11 slide in the moving groove 12. The inclined surface on one side of the positioning wedge 11 presses the spherical ball 9, and the spherical ball 9 is fixed in the limiting groove 13, and the mirror 3 is fixed, so that the mirror 3 will not move during use to cause the laser path to be disconnected.

[0022] A magnetic attraction seat 16 is fixed to one side of each base 6 away from the spherical ball 9, and the magnetic attraction seats 16 are all strongly magnetic and magnetically attracted in the cabinet body 1. The magnetic attraction setting can move flexibly and change the laser path at any time, so that the dust detection in the cabinet body 1 can be set flexibly.

[0023] Each temperature detection module 2 includes a housing 19, an air outlet 20 and an axial flow fan 21. The housing 19 is a hollow metal cavity. The two ends of the housing 19 are respectively connected to the air outlet 20 and the axial flow fan 21. A bracket 15 is arranged on one side of the housing 19 close to the air outlet 20. A contact switch 14 is arranged on the upper part of the bracket 15. A bimetallic strip is arranged on one side of the housing 19 close to the axial flow fan 21. The thermal expansion efficiency of copper is greater than that of iron, so that the bimetallic strip can trigger the contact switch 14 well to make the temperature detection module 2 flexibly control the heat dissipation mechanism in the cabinet body 1 to realize the heat dissipation of the cabinet body 1.

[0024] The bimetallic strip includes a copper sheet 17 and an iron sheet 18. The copper sheet 17 and the iron sheet 18 are fixedly attached to each other. The copper sheet 17 is arranged on one side of the air outlet end close to the axial flow fan 21. The tops of the copper sheet 17 and the iron sheet 18 are opposite to the induction part of the contact switch 14. The contact switch 14 is connected in parallel with the heat dissipation mechanism of the cabinet body 1. With the parallel connection setting, when the temperature detection module 2 at a certain position detects high temperature, the heat dissipation mechanism can work to dissipate heat at any time.

[0025] The obtuse angle formed by the connecting rod 8 and the end of the base 6 is between 90 and 160 degrees, which is convenient for adjusting the angle of the mirror 3, realizing the flexible adjustment of the laser path, and adapting to the flexible use and adjustment in the cabinet body 1.

[0026] Embodiment 2:

[0027] Referring to Figures 1-6 as shown, an embodiment of the present invention provides a method for abnormal status prompt inside a server cabinet. The device used for abnormal status prompt inside the server cabinet is the abnormal status prompt monitoring device inside the server cabinet described in the previous text, including the following steps: S1. Dust detection: a. Laser path debugging: Install a base 6 at the part inside the cabinet main body 1 that needs dust monitoring. Then, adjust the angle of the reflector 3 on the base 6 starting from the laser emission starting end, so that the reflectors 3 inside the cabinet main body 1 form a laser path that reflects a beam of light from top to bottom. At this time, turn the threaded rod 10 through the handle 7 to make the positioning wedge 11 slide in the moving groove 12. One inclined surface of the positioning wedge 11 presses against the ball 9, and the ball 9 is fixed in the limit groove 13, and the reflector 3 is fixed, and the laser path debugging is completed; b. Dust actual situation detection: The laser emitter 5 emits laser light to the first reflector 3 on the laser path, and the light is reflected from the last reflector 3 on the laser path in sequence and then irradiates on the light sensor 4. The light sensor 4 converts the data through an encoder and then transmits it to the monitoring platform through a signal line. Then, the dust concentration is inferred from the pipeline intensity of the light sensor 4; S2. Temperature detection: Place the temperature detection module 2 at a place inside the cabinet main body 1 where it is not easy to measure the temperature. The axial flow fan 21 extracts the surrounding temperature into the housing 19. The temperature causes the iron sheet 18 and the copper sheet 17 to thermally expand. After the copper sheet 17 expands, the bimetal sheet bends towards the contact switch 14. Adjust the distance between the bimetal sheet and the contact switch 14 to a distance suitable for the internal environment of the server cabinet. In this way, according to the expansion rate of the bimetal sheet, if the temperature does not meet the heat dissipation requirement, the bimetal sheet expansion will not trigger the contact switch 14. When the temperature exceeds the normal operating temperature inside the server, the bimetal sheet expands excessively and triggers the contact switch 14. At this time, the contact switch 14 closes, causing the parallel heat dissipation mechanism to work, and the inside of the cabinet main body 1 cools down.
