Description

Technical Field

[0001] The present application relates to the technical field of optical transport network equipment, and in particular to an optical transport network (OTN) equipment and a control method thereof. Background Art

[0002] OTN, or Optical Transport Network, is a type of network that implements the transmission, multiplexing, routing, and monitoring of service signals in the optical domain, and guarantees their performance indicators and survivability. OTN equipment, also known as OTN node equipment and OTN transmission equipment, is a device based on the optical transport network that implements the above functions.

[0003] As the demand for data transmission continues to increase, OTN equipment provides large-capacity transmission bandwidth to meet the growing demand for data transmission. However, large-capacity OTN equipment generates heat during operation. When used in the computer room, the equipment room air conditioner is used to cool it down. Small and medium-sized enterprises mostly use cabinets to set up OTN equipment. The side walls of the cabinets are equipped with air holes. The fans draw air from both sides of the cabinets into the cabinets and then blow it out from the top of the cabinets to take away the hot air for cooling. This is a side-entry air cooling method. However, the air cooling effect is not good, especially since most common OTN equipment is stacked on the cabinets and used synchronously. It is easy to be damaged by high temperature after long-term operation. Traditional air cooling can only increase the wind speed to increase the speed of hot air dissipation and the cooling speed. However, when the temperature rises to a certain level, especially when the equipment is used for a long time and the lines are aged, it is easy to have problems such as short circuits, which may cause greater accidents such as fires.

[0004] To this end, the present application provides an optical transport network (OTN) device and a control method to reduce the loss of equipment after high temperature rise and the probability of causing accidents.

When it reaches the set value 1, the alarm sounds, thereby issuing a warning and reminding; when it reaches the set value 2, the drive rod drives the pressure plate to descend and press down the crystal head, making the limit of the crystal head and the connector invalid; at the same time, the drive rod drives the lever to deflect, causing the stud to rotate, and the stud pushes the OTN transmission equipment body away, so that the crystal head is separated from the corresponding connector to prevent problems such as short circuits from extending along the line to other electrically connected devices, thereby reducing the impact and loss on other equipment.

[0022] 2. When the OTN transmission equipment body moves, the gas plate moves synchronously, so that the air hole is offset. At this time, the air channel and the through hole are no longer connected with the air hole, thereby isolating the installation cavity from the adjacent installation cavity, preventing the fire and other accidents of the OTN transmission equipment body in the installation cavity from spreading to the other OTN transmission equipment bodies or other equipment, further improving the protection of other equipment.

[0042] Principle details of this embodiment:

[0043] An optical transport network (OTN) device comprises a cabinet 1 and an OTN transmission device body 2 placed in the cabinet 1.

[0044] The OTN transmission equipment body 2 is a fixed box access type OTN transmission equipment body 2, and a row of interfaces 18 are provided at its end for connecting lines. The line connectors can be divided into crystal heads 16 and threaded heads 17 according to different types. The connector of the crystal head 16 is an insert type, and a pressable hook is provided on it. The corresponding interface 18 is also provided with a bayonet. The crystal head 16 is inserted into the interface 18 and will not fall off easily through the hook and the opening. The plug of the threaded head 17 is provided with a rotatable nut at the end, and the interface 18 is an external screw sleeve 8 structure. The threaded head 17 is firmly connected to the corresponding connector by screwing the thread.

[0045] The cabinet 1 is an open structure, and a chamber is provided inside the cabinet 1, and the chamber is connected from front to back. An exhaust port is provided on the top wall of the chamber, and a fan is provided at the exhaust port. An embedded groove is provided on the bottom wall of the chamber, and multiple rows of through holes 5 are evenly distributed on the bottom wall of the embedded groove, and the hole spacing of multiple through holes 5 in each row of through holes 5 and the spacing between each row of through holes 5 are equal. An air duct 4 is provided on the side wall at the bottom wall of the cabinet 1, which is mutually connected with each row of through holes 5. An air plate 3 is embedded in the embedded groove, so that the air plate 3 can be slidably installed in the embedded groove. The width of the air plate 3 is equal to that of the embedded groove, and the length of the air plate 3 is less than the length of the embedded groove. Air holes 6 corresponding to the through holes 5 are evenly distributed on the air plate 3.

[0046] See attached Fig.12As shown, a support is provided on the cabinet body 1 at the side connected to the crystal head 16 on the OTN transmission equipment body 2 (in the present embodiment, this direction is the positive direction), and a screw sleeve 8 is provided on the side of the support facing the OTN transmission equipment body 2, and a stud 7 is screwed into the inner thread of the screw sleeve 8, and the stud 7 is against the end face of the OTN transmission equipment body 2. A rotating shaft 11 is rotatably mounted on the support, and the axis of the rotating shaft 11 coincides with the axis of the stud 7. A lever 12 is sleeved on the end of the rotating shaft 11, and the lever 12 is fastened to the rotating shaft 11 via a spline and a spline groove, so that the lever 12 and the rotating shaft 11 rotate synchronously and in the same direction. A rectangular hole is provided at the axis center of the rotating shaft 11, and a rectangular shaft 10 is inserted into the rectangular hole. The rectangular shaft 10 is fixedly connected to the end of the stud 7, so that the stud 7 and the lever 12 are relatively axially slidably matched. For matching, refer to the attached Fig.15 As shown, a driving rod 14 is vertically slidably installed on the front side of the cabinet 1. The driving rod 14 is driven by a fixed component to move vertically back and forth. The driving component is an electric telescopic rod. A C-shaped buckle 23 is fixed to the side wall of the lower end of the driving rod 14. A notch is provided on the lever 12. The C-shaped buckle 23 is hooked in the notch, so that the lever 12 is hooked with the driving rod 14.

[0047] The side walls of the driving rod 14 are provided with a pressure plate 15 above the crystal head 16 of the OTN transmission equipment body 2 .

[0048] In this embodiment, a temperature sensor is provided in the chamber in the cabinet 1 , and the temperature sensor is electrically connected to the driving component and the alarm.

[0049] In this embodiment, the side walls of the inner chamber of the cabinet 1 and the surface of the air plate 3 are provided with protrusions, so that there is a gap between the OTN transmission equipment body 2 and the inner wall of the chamber of the cabinet 1 to prevent the surface of the OTN transmission equipment body 2 from being attached to the inner wall of the inner chamber of the cabinet 1 and affecting the flow of hot air.

[0050] According to the above technical solution:

[0051] When in use, the OTN transmission equipment body 2 is placed in the chamber of the cabinet 1, and the stud 7 is retracted in the screw sleeve 8, so that the air hole 6 on the air plate 3, the through hole 5 of the embedded groove, and the air passage 4 through the side wall of the cabinet 1 are in a through state. Fig.10 The air hole 6, through hole 5, and air channel 4 are connected as shown in the upper middle figure. At this time, under the traction of the fan, the air on both sides of the cabinet 1 enters the air channel 4, and then enters the chamber of the cabinet 1 along the through hole 5 and the air hole 6. The airflow flows along the surface of the OTN transmission equipment body 2 and the heat dissipation port, and finally is discharged from the exhaust port on the top wall of the cabinet 1, so that the heat generated by the operation of the equipment is dissipated along with the airflow to achieve the purpose of heat dissipation. When the temperature sensor detects that the temperature of the solid inner chamber has increased, the speed of the fan increases to speed up the circulation rate of the hot air flow and improve the heat dissipation efficiency.

[0052] When the heat dissipation effect is not good, the temperature of the inner chamber of the cabinet 1 continues to rise. When it reaches the set value 1, the alarm sounds, thereby issuing a warning and reminding.

[0053] When the setting value 2 is reached (setting value 1 is less than setting value 2) or a fire has occurred in the cabinet 1, the temperature of the chamber in the cabinet 1 reaches its peak, which can easily cause accidents such as short circuit fire. At this time, the driving assembly drives the driving rod 14 to descend, and the driving rod 14 drives the pressure plate 15 to descend, and the pressure plate 15 presses down the hook of the crystal head 16, unlocking the crystal head 16 and the corresponding joint, so that the crystal head 16 is no longer tightly connected with the corresponding joint; At the same time, the driving rod 14 deflects the lever 12 through the cooperation of the C-shaped buckle 23 and the notch, thereby rotating the stud 7 through the cooperation of the rotating shaft 11, the rectangular hole, and the rectangular shaft 10. Since the stud 7 and the screw sleeve 8 are threadedly matched, the stud 7 extends out of the screw sleeve 8 and moves against the OTN transmission equipment body 2, thereby pushing the OTN transmission equipment body 2 away, so that the crystal head 16 is separated from the corresponding joint, so as to prevent the short circuit and other problems from extending along the line to other electrically connected devices, thereby reducing the impact and loss on other devices. While the OTN transmission device body 2 moves, the gas plate 3 pressed by the OTN transmission device body 2 moves synchronously, so that the air hole 6 is offset. At this time, the air channel 4 and the through hole 5 are no longer connected with the air hole 6, thereby isolating the installation cavity from the adjacent installation cavity, preventing the fire and other accidents of the OTN transmission device body 2 in the installation cavity from spreading to the other OTN transmission device bodies 2 or other devices, further improving the protection of other equipment.

[0054] According to the above technology, when the temperature rises too high or a fire occurs, the crystal head 16 is separated from the OTN transmission equipment body 2 to prevent problems such as short circuits from affecting other devices electrically connected to it along the line, thereby increasing the protection of other devices; at the same time, the gas plate 3 is offset, and the air channel 4 and the through hole 5 are no longer connected to the air hole 6, thereby isolating the installation cavity from the adjacent installation cavity, preventing accidents such as fire in the OTN transmission equipment body 2 in the installation cavity from extending to the remaining OTN transmission equipment bodies 2 or other devices, thereby further improving the protection of other equipment.

[0055] Embodiment 2, a further embodiment of the present scheme, in the above embodiment, the driving rod 14 is directly connected to the lever 12 through the C-shaped buckle 23. When the driving rod 14 moves, the pressure plate 15 does not press the hook of the crystal head 16, and the stud 7 has moved against the OTN transmission equipment body 2, and it is difficult to ensure that the crystal head 16 and the connector are completely separated. Therefore, in this embodiment, in order to make the limit between the hook on the crystal head 16 and the bayonet of the connector fail before the OTN transmission equipment body 2 is pushed away, in this embodiment: the side wall of the cabinet 1 is located directly below the driving rod 14 and is vertically slidably installed with a pressure rod 13, a spring 1 is provided between the pressure rod 13 and the side wall of the cabinet 1, and the side wall of the pressure rod 13 is hung with the lever 12, and each pressure plate 15 is provided with a slot in the center, and the driving rod 14 passes through the pressure plate 15 from the slot, and a spring 2 is provided between the pressure plate 15 and the driving rod 14.

[0056] Principle details of this embodiment:

[0057] A fixing sleeve is fixed to the front side of the cabinet 1 just below the driving rod 14, and the upper end of the fixing sleeve is open. A pressure rod 13 is vertically slidably installed in the opening of the fixing sleeve, and a C-shaped buckle 23 is arranged on the side wall of the pressure rod 13, so that the pressure rod 13 is hooked with the lever 12. A spring 1 is arranged between the pressure rod 13 and the bottom wall of the fixing sleeve to drive the pressure rod 13 to reset after being offset. The lower end of the driving rod 14 is spaced apart from the upper end of the pressure rod 13, and the size of the spacing is equal to the spacing between the pressure plate 15 and the crystal head 16. A slot is arranged in the center of each pressure plate 15, and the driving rod 14 passes through the pressure plate 15 from the slot. A convex ring corresponding to the pressure plate 15 is arranged on the side wall of the driving rod 14, and a spring 2 is fixed on the convex ring, and the lower end of the spring 2 is fixedly connected to the pressure plate 15.

[0058] According to the above technical solution:

[0059] Through the cooperation between the slot and the second spring, the pressure plate 15 can move synchronously with the driving rod 14 when not under force, and can drive the rod 14 to move alone when under force. In this way, when the driving rod 14 descends, the pressure plate 15 presses down on the hook of the crystal head 16 until the limit between the hook and the bayonet fails; then the lower end of the driving rod 14 abuts on the pressure rod 13, thereby pressing the pressure rod 13 down, and the pressure rod 13 descends, thereby driving the stud 7 to move the OTN transmission equipment body 2 against it, so that the crystal head 16 is separated from the corresponding interface 18. In this way, the driving is carried out successively to achieve the purpose of failing the limit between the hook on the crystal head 16 and the bayonet of the connector before the OTN transmission equipment body 2 is pushed away.

[0060] Embodiment 3, in a further embodiment of the present solution, in the above embodiment, the hook of the crystal head 16 is pressed down by the pressing plate 15 so that the hook is separated from the latch, and then when the stud 7 is pushed away from the OTN transmission device body 2, the crystal head 16 is separated from the connector. However, there is no way to keep the crystal head 16 in position by only pressing down the crystal head 16 by the pressing plate 15. When the OTN transmission device body 2 is pushed away, the crystal head 16 may move with it, and there is no way to separate all the corresponding crystal heads 16 from the connector. Therefore, in the present embodiment, a top plate 19 is fixed on the side wall of the cabinet 1 below the crystal head 16 located on the OTN transmission device body 2. The top plate 19 is against the lower end surface of the crystal head 16.

[0061] According to the above technical solution:

[0062] When in use, the pressure plate 15 presses down on the upper end surface of the crystal head 16, and the top plate 19 abuts against the lower end surface of the crystal head 16, and the two cooperate to form a clamping effect, thereby ensuring that the crystal head 16 is completely separated from the OTN transmission equipment body 2 after it is pushed away.

[0063] Embodiment 4, in a further embodiment of this solution, the stud 7 moves against the OTN transmission device body 2, and moves with the gas plate 3 by pressing the OTN transmission device body 2 on the gas plate 3, which inevitably affects the stability and certainty of the movement of the gas plate 3. Therefore, in this embodiment, a rib plate 9 is fixed to the end of the gas plate 3, the OTN transmission device body 2 is against the rib plate 9, and the end of the stud 7 is against the side wall of the rib plate 9 away from the OTN transmission device body 2.

[0064] Principle details of this embodiment:

[0065] The bottom wall of the installation cavity is provided with a communicating notch at the front end of the embedding groove, and an L-shaped rib plate 9 is fixed to the end of the gas plate 3. The horizontal end of the rib plate 9 passes through the notch, and the vertical end of the rib plate 9 abuts against the front end surface of the OTN transmission equipment body 2. The stud 7 abuts against the front end surface of the rib plate 9.

[0066] According to the above technical solution:

[0067] The stud 7 presses against the rib plate 9, and the rib plate 9 moves to dislocate the air hole 6, isolating the installation cavity; at the same time, the rib plate 9 presses against the OTN transmission equipment body 2 to move, thereby ensuring the stability and certainty of the movement of the air plate 3 and the OTN transmission equipment body 2.

[0068] Embodiment 5, in a further embodiment of the present scheme, in addition to the connector corresponding to the crystal head 16, most OTN transmission equipment bodies 2 are also provided with connectors corresponding to the threaded heads 17. The crystal heads 16 and the threaded heads 17 are mostly arranged in a row. If you want to separate the threaded head 17 from the corresponding interface 18, you need to screw it. Therefore, in this embodiment, the bottom end of the pressure plate 15 is located above the threaded head 17 of the OTN transmission equipment body 2 and is horizontally slidably installed with a friction plate 22, and a ∩-shaped bracket 21 is fixed to the bottom end of the friction plate 22, and a rod 20 that cooperates with the bracket 21 is provided on the side wall of the rotating shaft 11 of the lever 12.

[0069] Principle details of this embodiment:

[0070] Each pressure plate 15 is provided with a slide groove on the lower end surface, and the slide groove is located directly above the thread head 17 of the OTN transmission equipment body 2. A friction plate 22 is slidably installed in the slide groove. The friction plate 22 is a plate with a friction layer on the surface, which is used to increase the friction resistance. A ∩-shaped plug-in bracket 21 is fixed to the bottom end of the friction plate 22, and a plug-in rod 20 that cooperates with the plug-in bracket 21 is provided on the side wall of the rotating shaft 11 of the lever 12, that is, on the side wall of the rotating shaft 11. The plug-in rod 20 is spaced apart from the lever 12. The thread pitch between the thread head 17 and the corresponding joint is large, so that the thread head 17 can be separated from the corresponding joint by rotating a few circles.

[0071] According to the above technical solution:

[0072] When in use, the pressure plate 15 presses down on the crystal head 16, and the friction plate 22 presses against the threaded head 17, and the end of the plug rod 20 is inserted into the plug rack 21. When the driving rod 14 presses down the pressure rod 13, the pressure rod 13 descends and synchronously drives the lever 12 and the plug rod 20 to deflect. The lever 12 deflects and pushes the OTN transmission equipment away; the plug rod 20 deflects and presses against the plug rack 21, thereby driving the friction plate 22 to slide in the slide groove, and using the friction resistance to drive the threaded head 17 to rotate, so as to separate the threaded head 17 from the corresponding connector. The purpose of controlling the separation of different connectors from the line plug is achieved.

[0073] Embodiment 6, in a further embodiment of the present solution, the depth of the chamber of the cabinet 1 is adapted to the OTN transmission device body 2. Thus, when the stud 7 pushes out the OTN transmission device body 2, the rear end of the OTN transmission device body 2 extends out from the rear side of the installation cavity of the cabinet 1, which is convenient for quick grabbing and taking out from the cabinet 1, reducing the time that the OTN transmission device body 2 in an accident and other devices are in a small space, thereby reducing the loss of intact equipment.

[0074] Embodiment 7, in a further embodiment of the present solution, a sealing plate 25 is detachably mounted on the cabinet 1 at the side where the OTN transmission equipment body 2 and the crystal head 16 are connected, and a plurality of notches are provided on the sealing plate 25 for the lines to pass through.

[0075] An L-shaped plate 24 is rotatably mounted on the cabinet 1 at the side away from the sealing plate 25, and a top rod is provided on the bottom wall of the gas plate 3 to cooperate with the L-shaped plate 24. A sinking groove is provided at the bend of the L-shaped plate 24. The length of the horizontal part of the L-shaped plate 24 does not exceed the length of the top rod.

[0076] When the stud 7 is retracted in the nut, the air hole 6, the through hole 5, and the air passage 4 are connected, and the push rod is against the horizontal part of the L-shaped plate 24. Fig.13 As shown, the vertical part of the L-shaped plate 24 stands upright. The sealing plate 25 cooperates with the L-shaped plate 24 to firmly buckle the OTN transmission equipment body 2 in the installation cavity of the cabinet 1. When the stud 7 moves against the OTN transmission equipment body 2, the push rod moves along the horizontal part of the L-shaped plate 24; when the end of the gas plate 3 is against the vertical part of the L-shaped plate 24, the push rod is located in the sinking groove. When the gas plate 3 continues to extend outward, it will deflect against the L-shaped plate 24, so that the rear end of the installation cavity of the cabinet 1 is opened, which does not affect the removal of the OTN transmission equipment.

[0077] Embodiment 8, in a further embodiment of the present invention, the stud 7 is rotatably connected to the rib plate 9. The stud 7 is integrated with the air plate 3 through the rib plate 9, and when the stud 7 is recovered into the screw sleeve 8, the air plate 3 is simultaneously reset, and no manual adjustment is required, thereby simplifying the operation.

[0078] In this solution, the OTN transmission equipment body 2 is mostly provided with multiple rows of interfaces 18, so each OTN transmission equipment body 2 needs to be provided with multiple groups of pressure plates 15 and friction plates 22. Connecting columns are fixed between the multiple pressure plates 15 of the same OTN transmission equipment body 2, so that the adjacent pressure plates 15 are stacked and fixed. An opening is provided on each pressure plate 15, and a connecting column is also provided on the upper end of the friction plate 22, so that the adjacent friction plates 22 are stacked and fixed. The connecting column on the friction plate 22 passes through the opening, and the length of the opening is the same as the moving spacing of the friction plate 22.

[0079] A control method for an optical transport network OTN device:

[0080] Obtain temperature change data in the monitoring space;

[0081] Determine the heat dissipation mode based on temperature measurement data and control the heat dissipation of the equipment;

[0082] When the set value 1 is exceeded, a slow buzzer warning is issued and the heat dissipation power is increased; when the set value 2 is exceeded, a rapid buzzer warning is issued and the OTN transmission equipment body 2 is separated and isolated at the same time.

[0083] The specific use process of this program:

[0084] The driving assembly drives the driving rod 14 to descend, and the driving rod 14 drives the pressure plate 15 to descend. The pressure plate 15 presses down on the upper end surface of the crystal head 16, and the top plate 19 rests on the lower end surface of the crystal head 16. The two cooperate to form a clamping effect, so that the crystal head 16 is no longer tightly connected to the corresponding joint.

[0085] Then the lower end of the driving rod 14 abuts against the pressure rod 13, thereby pressing the pressure rod 13 downward, and the pressure rod 13 descends, and the lever 12 deflects through the cooperation of the C-shaped buckle 23 and the notch, thereby rotating the stud 7 through the cooperation of the rotating shaft 11, the rectangular hole, and the rectangular shaft 10. Since the stud 7 and the screw sleeve 8 are threadedly matched, the stud 7 extends out of the screw sleeve 8 and moves against the rib plate 9, and the rib plate 9 moves against the OTN transmission equipment body 2, thereby pushing the OTN transmission equipment body 2 away, so that the crystal head 16 is separated from the corresponding connector, so as to prevent problems such as short circuits from affecting other devices electrically connected to it along the line, thereby increasing the protection of other devices.

[0086] While the OTN transmission device body 2 moves, the air plate 3 moves synchronously with the rib plate 9, so that the air hole 6 is offset. At this time, the air channel 4 and the through hole 5 are no longer connected with the air hole 6, thereby isolating the installation cavity from the adjacent installation cavity, preventing the fire or other accidents in the OTN transmission device body 2 in the installation cavity from extending to the other OTN transmission device bodies 2 or other devices.

[0087] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and application concept of the present application, which should be covered by the protection scope of the present application.
