Description

Technical Field

[0001] The present invention relates to the technical field of audio - visual data processing temperature monitoring, and particularly to an intelligent analysis and monitoring device for audio - visual data. Background Art

[0002] The data volumes of audio files and video files of audio - visual data are huge. When performing analysis and processing, a large number of servers are required. When the servers are running, temperature control is needed, and the running temperature being in a constant or approximately constant state can improve the running efficiency of the servers. That is to say, both too low and too high server temperatures will affect their running efficiency.

[0003] Currently, the servers used for audio - visual data processing are usually centrally placed in a dedicated computer room. An air conditioner is installed in the computer room, and the air conditioner provides cold air to the computer room, and then a temperature control component is used to control the temperature in the computer room so that the overall temperature in the computer room is in a constant state. However, there are still deficiencies in the use of this temperature monitoring method: the temperature monitoring can only monitor the overall temperature of the computer room and it is difficult to monitor the temperature of a single server during operation. That is to say, there are problems where the operating temperatures of some servers are too high and some are too low, and thus, the overall operating efficiency of the servers will be affected.

[0004] Therefore, the present invention proposes an intelligent analysis and monitoring device for audio - visual data, which is used to monitor the temperature of a single server during analysis, operation, and processing. Summary of the Invention

[0012] As a further description of the above technical solution:

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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.

[0036] Embodiment 1

[0037] Please refer to Figures 1-7 , an intelligent analysis and monitoring device for audio-visual data, including a physical monitoring unit 1 and several servers 2. The server 2 includes a chassis 21, and components such as a circuit board, a microprocessor, and a memory for data analysis and processing are installed in the chassis 21. The function of the physical monitoring unit 1 is to monitor the operating temperature of each server 2. When the temperature is too high, cooling treatment is carried out, and when the temperature is too low, heating treatment is carried out. Among them, cooling and heating are achieved by transferring cold air to control the temperature.

[0038] Specifically, the physical monitoring unit 1 includes a cold air shunt cylinder 11 and a transfer pipe 12. The cold air shunt cylinder 11 is used for the turnover of cold air. Preferably, in specific implementation, the cold air shunt cylinder 11 is in a cylindrical structure and an air inlet pipe 113 is provided at its top. A concave portion 114 is fixedly provided in the middle of the bottom of the cold air shunt cylinder 11, and the outer peripheral wall of the concave portion 114 is fixedly connected to the outer peripheral wall of the conical cover 112. Among them, the air inlet pipe 113 is a connecting pipe for cold air to enter the cold air shunt cylinder 11. A plurality of positioning pipes 111 evenly distributed in the circumferential direction are fixedly connected to the outer peripheral wall of the cold air shunt cylinder 11. When the cold air shunt cylinder 11 circulates cold air, the cold air will be discharged through the positioning pipes 111. A transfer pipe 12 that is axially slidably fitted is sleeved in the positioning pipe 111. A conical cover 112 corresponding to the transfer pipe 12 is fixedly connected in the cold air shunt cylinder 11. The inner conical wall of the conical cover 112 faces one end of the transfer pipe 12. Thus, when the cold air in the cold air shunt cylinder 11 is discharged outward, the cold air will first enter the conical cover 112 and then be discharged through the transfer pipe 12. When the transfer pipe 12 moves axially, the flow cross-section between the transfer pipe 12 and the conical cover 112 will be adjusted, and thus the flow rate of the air flow in the transfer pipe 12 can be adjusted.

[0039] The physical monitoring unit 1 includes a discharge pipe 13. One end of the discharge pipe 13 extends into the chassis 21 and the other end is connected to the transfer pipe 12 through a pipeline. One discharge pipe 13 is correspondingly installed for one chassis 21. The cold air discharged from the transfer pipe 12 will enter the corresponding discharge pipe 13 and then enter the chassis 21 to achieve the cooling treatment of the chassis 21.

[0040] Further, there is a control module in the physical monitoring unit 1. This control module includes a central processing unit and a temperature sensor 14. The temperature sensor 14 is located inside the chassis 21 for the purpose of detecting the temperature inside the chassis 21 and then transmitting the temperature data to the central processing unit. The physical monitoring unit 1 further includes a shunt control mechanism 15. The shunt control mechanism 15 is electrically connected to the central processing unit. The central processing unit installs a program to operate the shunt control mechanism 15. The shunt control mechanism 15 has the function of controlling the axial sliding of any discharge pipe 13, thereby controlling the flow rate of the cold air entering the chassis 21. It should be noted that the shunt control mechanism 15 adjusts the temperature inside the problem chassis 21 in a way of offsetting each other. Simply put, it transfers part of the cold air in the chassis 21 with too low operating temperature to the chassis 21 with high operating temperature. This setting makes the flow rate of the cold air entering the cold air shunt cylinder 11 unchanged, and the cold air volume in other chassis 21 remains constant, thereby greatly improving the overall operating efficiency of all servers 2.

[0041] Specifically, the shunt control mechanism 15 includes a transmission sleeve 151, a transmission disk 152, and a driving ring 153. The transmission sleeve 151 is sleeved outside the positioning pipe 111 and the two are rotationally matched. The transmission sleeve 151 is also screwed and matched with the adjacent transfer pipe 12. Preferably, during specific implementation, a transmission thread 1511 is provided on the inner peripheral wall of the transmission sleeve 151, and a shifting shaft 122 located in the thread groove of the transmission thread 1511 is fixedly connected to the outer peripheral wall of the transfer pipe 12. Thus, when the transmission sleeve 151 rotates, the transmission thread 1511 will push the transfer pipe 12 to move axially through the shifting shaft 122. Therefore, when the transmission sleeve 151 rotates, it can use the screwing action to control the axial movement of the transfer pipe 12. The number of transmission disks 152 is two and they are sleeved outside the cold air shunt cylinder 11. The two transmission disks 152 are located on the upper and lower sides of the transfer pipe 12. The transmission disks 152 are slidably matched with the cold air shunt cylinder 11 up and down. A driving ring 153 is fixedly sleeved outside the transmission disk 152. An arc-shaped tapered rack 1531 is fixedly connected to one side of the driving ring 153 facing the transfer pipe 12. A transmission bevel gear 1512 meshing with the arc-shaped tapered rack 1531 is fixedly sleeved on the transmission sleeve 151. When controlling the rotation of the driving ring 153, it can control the arc-shaped tapered rack 1531 thereon to face the transmission bevel gears 1512 on different transfer pipes 12. When controlling the two transmission disks 152 to move towards and away from each other, it can control the arc-shaped tapered rack 1531 to mesh with the adjacent transmission bevel gears 1512. Then, by controlling the forward and reverse rotation of the two driving rings 153, the cold air outlet volumes of any two transfer pipes 12 can be adjusted simultaneously. For example, when the outlet volume of one transfer pipe 12 decreases, the outlet volume of the other transfer pipe 12 increases.

[0042] Furthermore, the flow splitting control mechanism 15 further includes a first control assembly 154 for controlling the synchronous opposite and reverse sliding of the two driving disks 152, and a second control assembly 155 for controlling the same-direction and reverse rotation of the driving rings 153 on the two driving disks 152. The overall function of the flow splitting control mechanism 15 is to adjust the position of the arc-shaped taper rack 1531, and then drive the target transmission sleeve 151 to rotate forward and backward.

[0043] Specifically, the first control assembly 154 includes a bidirectional lead screw 1541, an upper nut 1542, a lower nut 1543, and a first control motor 1544. A positioning plate 115 is welded to the outer peripheral wall of the cold air flow splitting cylinder 11. The bidirectional lead screw 1541 passes through and is sleeved on the positioning plate 115 and is rotatably connected to the positioning plate 115. The upper nut 1542 and the lower nut 1543 are sleeved on the bidirectional lead screw 1541 and are respectively fixedly connected to the driving rings 153 on the upper and lower sides of the adapter pipe 12. Specifically, through holes for fixedly connecting the upper nut 1542 or the lower nut 1543 can be provided on the driving ring 153 during implementation. The thread directions in the upper nut 1542 and the lower nut 1543 are opposite. The first control motor 1544 is fixedly arranged at the bottom of the cold air flow splitting cylinder 11, and its output shaft is fixedly connected to the bottom of the bidirectional lead screw 1541. The first control motor 1544 provides driving force for the forward and reverse rotation of the bidirectional lead screw 1541.

[0044] Among them, the second control assembly 155 includes a transmission shaft 1551. One end of the positioning plate 115 is welded with a channel-shaped plate 1151. The number of transmission shafts 1551 is two and they are respectively rotatably connected to the side plates 11511 on the channel-shaped plate 1151. The two transmission shafts 1551 are coaxial, and transmission gears 15511 meshing with the outer periphery of the adjacent driving rings 153 are fixedly sleeved on the two transmission shafts 1551. That is to say, one transmission shaft 1551 corresponds to one driving ring 153. When the two transmission shafts 1551 rotate in the same direction synchronously, they can drive the two driving rings 153 to rotate in the same direction synchronously. When the two transmission shafts 1551 rotate in the reverse direction, they can drive the two driving rings 153 to rotate in the reverse direction. The second control assembly 155 includes a conversion controller 1552 for controlling the same-direction and reverse rotation of the two transmission shafts 1551.

[0045] Specifically, the conversion controller 1552 includes a telescopic rod 15521, a limit gear 15522, a limit bevel gear 15523, an intermediate gear 15524, a rectangular frame 15525, and a control motor two 15526. The telescopic rod 15521 is arranged on the positioning plate 115, and its moving end is fixedly connected to one end of the rectangular frame 15525. Specifically, an installation cavity can be opened on the positioning plate 115 and the channel-shaped plate 1151 during implementation, and the telescopic rod 15521 is installed in the installation cavity. During use, the telescopic rod 15521 can be an electric push rod or a control cylinder. The rectangular frame 15525 is located within the channel-shaped plate 1151. When the telescopic rod 15521 moves, it can drive the rectangular frame 15525 to move left and right within the channel-shaped plate 1151. Intermediate gears 15524 located within the rectangular frame 15525 are fixedly sleeved on both of the two transmission shafts 1551. The limit gear 15522 is rotatably connected within the rectangular frame 15525 and meshes with the intermediate gear 15524. The limit bevel gear 15523 is rotatably connected to one end within the rectangular frame 15525. Opposite ends of the intermediate gears 15524 on the two transmission shafts 1551 are fixedly connected with intermediate bevel gears 155241 that mesh with the limit bevel gear 15523. Thus, when the rectangular frame 15525 drives the limit gear 15522 to approach the intermediate gear 15524 until they mesh, the limit bevel gear 15523 will separate from the two intermediate bevel gears 155241. At this time, the two transmission shafts 1551 will rotate synchronously and in the same direction. Conversely, the limit bevel gear 15523 will mesh with the two intermediate bevel gears 155241, and the limit gear 15522 will separate from the intermediate gear 15524. At this time, the two transmission shafts 1551 will rotate in opposite directions. The control motor two 15526 is arranged at the top of the channel-shaped plate 1151, and its output shaft is fixedly connected to the top of the adjacent transmission shaft 1551. The control motor two 15526 provides driving force for the rotation of one of the transmission shafts 1551. When the limit gear 15522 separates from the intermediate gear 15524 and the limit bevel gear 15523 separates from the intermediate bevel gear 155241, the control motor two 15526 can control the rotation of a single drive ring 153 through the corresponding transmission shaft 1551.

[0046] In this embodiment, one end of the discharge pipe 13 is fixedly connected to a flow dividing disk 131 located within the chassis 21. The flow dividing disk 131 is of a hollow structure, and air outlet holes 1311 evenly distributed are opened at its bottom. The setting of the flow dividing disk 131 enables the cold air entering the chassis 21 to be in a dispersed flow state, accelerating the filling of the chassis 21 with cold air. The temperature sensor 14 is fixedly arranged on the top of the flow dividing disk 131.

[0047] Working principle: When in use, install the cold air shunt cylinder 11 in the computer room, suspend and connect multiple discharge pipes 13 through brackets, then arrange the chassis 21 on the storage rack, and introduce the cold air generated by an external air cooler into the intake pipe 113 through a pipeline. In the normal operation state, the cold air in the cold air shunt cylinder 11 will be introduced into the corresponding chassis 21 through each adapter pipe 12, so that each server 2 is in a state of ventilation, cooling and temperature reduction. However, due to the different loads of all the servers 2, their operating temperatures are also different. As a result, one server 2 will have the highest operating temperature and another server 2 will have the lowest operating temperature. At this time, the temperature sensor 14 transmits the detected temperature to the central processor. After processing, the central processor starts the control motor one 1544, the control motor two 15526 and the telescopic rod 15521 to act, so that the two driving disks 152 move in the opposite direction. Then, control the two driving rings 153 to rotate in the same and opposite directions, so that the arc-shaped bevel gears 1531 on the two driving rings 153 and the driving bevel gears 1512 on the adapter pipe 12 whose exhaust volume needs to be adjusted face each other. Then, control the two driving disks 152 to move towards each other, and the arc-shaped bevel gear 1531 meshes with the corresponding driving bevel gear 1512. Finally, control the two driving rings 153 to rotate in the same or opposite directions. At this time, the two driven adapter pipes 12 will move axially, so that the cold air flow in one adapter pipe 12 increases and the cold air flow in the other adapter pipe 12 decreases, thereby eliminating the temperature difference between the two servers 2 and making all the servers 2 operate in an overall approximate constant temperature state.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
