Description
Technical Field
[0001] The present application relates to the technical field of optical fibers, and in particular to an OLT optical fiber fault warning and positioning device in an EPON network. Background Art
[0002] EPON OLT optical fiber equipment plays the role of core equipment in Ethernet Passive Optical Network (EPON).
[0003] EPON OLT fiber optic equipment usually consists of the following parts: Control board (main control board): responsible for managing the entire OLT equipment, including data processing, protocol conversion and other functions. The main control board usually has a redundant design to improve the reliability and stability of the equipment. Uplink board: provides an interface with the upper-layer network, such as GE (Gigabit Ethernet) optical interface board, etc., to achieve connection with aggregation switches or BRAS (broadband remote access server) and other devices. Power board: provides a stable DC power supply for OLT equipment. Fan unit: responsible for the heat dissipation and environmental monitoring of the equipment to ensure that the equipment runs at an appropriate temperature. Frame (service frame): used to install and fix the above-mentioned boards to form a complete OLT device.
[0004] EPON OLT fiber optic equipment is widely used in the fields of home broadband access, enterprise dedicated line access, base station transmission, etc. In terms of home broadband access, EPON OLT distributes fiber optic signals to users' homes through the ODN network, providing users with high-speed and stable Internet access services. There are many families using EPON OLT fiber optic equipment, and the staff usually set up multiple cabinets for placing EPON OLT fiber optic equipment. However, when the EPON OLT fiber optic equipment fails, although the staff can determine which device has failed through user feedback, the staff needs to search for the location of the device in multiple cabinets, which greatly increases the workload of the staff. In order to solve this technical problem, the existing technology will set an alarm on the EPON OLT fiber optic equipment. When the EPON OLT fiber optic equipment fails, the alarm will send a signal to the main console and alarm at the same time to facilitate the staff to find the faulty fiber optic equipment.
[0005] Although the setting of the alarm can facilitate the staff to find the faulty fiber optic equipment, the alarm usually sounds the alarm through sound and light. This means that although the alarm sound can provide certain help to the staff, it is still not very obvious. Therefore, an OLT fiber optic fault warning and positioning device in the EPON network is needed. Summary of the invention
[0006] In view of the shortcomings of the prior art, the purpose of this application is to provide an OLT optical fiber fault warning and positioning device in an EPON network, which is used to solve the technical problem that the positioning of the faulty optical fiber equipment in the prior art is not very accurate.
[0007] The above-mentioned purpose of the present application is achieved through the following technical solutions: an OLT optical fiber fault warning and positioning device in an EPON network, comprising an EPON OLT optical fiber device body, a placement cabinet for placing the EPON OLT optical fiber device body, and an alarm device installed on the EPON OLT optical fiber device body, an opening is provided on one side of the placement cabinet, two opposite fixing plates are provided on one side of the opening, the two fixing plates are respectively fixedly provided at the upper and lower ends of the placement cabinet, a cabinet door rotatably connected to the fixing plate is provided between the two fixing plates, a rebound tension spring is provided between the cabinet door and the outer side of the placement cabinet, one end of the rebound tension spring is fixedly connected to the outer side of the placement cabinet, and the other end is fixedly connected to the outer side of the cabinet door, a plug-in sheet is provided on the inner side of the cabinet door, a plug-in interface is provided on the side of the opening away from the cabinet door, and a self-locking device for signal connection alarm device is provided on one side of the plug-in interface.
[0008] By adopting the above technical solution, when the alarm device detects a fault in the EPON OLT optical fiber device body, it sends a start signal to the self-locking device while sounding an alarm. The self-locking device receives the start signal and starts the output end to rotate so that the output end of the self-locking device no longer buckles the plug-in piece. The plug-in piece is not restricted by the self-locking device, causing the rebound tension spring to pull the cabinet door to rotate outside the placement cabinet, so that the cabinet door is opened. In this way, when the staff comes here following the alarm sound, it can be easily observed that the cabinet door of one of the multiple placement cabinets is open, so that the staff can quickly find the placement cabinet where the faulty EPON OLT optical fiber device body is located, thereby saving the staff's time in searching for the placement cabinet, saving the staff's workload and improving the staff's work efficiency.
[0009] Furthermore, the self-locking device includes a placement shell located on one side of the plug interface, a self-locking motor located inside the placement shell and fixedly connected to the placement shell, and a self-locking rod fixedly connected to the output end of the self-locking motor. A plug-in notch is provided on one side of the plug-in piece to facilitate the insertion of the self-locking rod. The plug-in notch runs through the upper and lower ends of the plug-in piece. The placement shell is fixedly connected to the placement cabinet and one side adjacent to the plug interface is connected to the plug interface. The self-locking motor signal is connected to an alarm device.
[0010] By adopting the above technical solution, when the cabinet door is in a closed state, the self-locking rod extends into the plug-in notch to clamp the plug-in plate, thereby preventing the rebound tension spring from pulling the cabinet door open. When the self-locking motor receives the start signal of the alarm device, it rotates to disengage the self-locking rod from the plug-in notch. At this time, the plug-in plate is not restricted, causing the cabinet door to be pulled open by the rebound tension spring.
[0011] Furthermore, a plurality of partition plates are provided in the storage cabinet, and the plurality of partition plates are arranged in a linear array along the height direction of the storage cabinet with intervals between the plurality of partition plates, and a pushing device and a limiting device are provided at one end of the upper surface of each partition plate away from the opening.
[0012] Furthermore, the limit device includes a limit motor fixedly connected to the placement cabinet and a limit plate fixedly connected to the circumferential surface of the output end of the limit motor, the pushing device includes a push-back spring, one end of the push-back spring is fixedly connected to the inner wall of the placement cabinet, and the other end is fixedly abutted against the limit plate, a side of the limit plate away from the push-back spring faces the end face of the EPON OLT optical fiber equipment body away from the opening, and the limit motor signal is connected to the alarm device.
[0013] By adopting the above technical scheme, although the setting of the self-locking device can make the cabinet door of the placement cabinet where the EPON OLT optical fiber device body is located open when the EPON OLT optical fiber device body fails, it is convenient for the staff to find the faulty EPON OLT optical fiber device body. However, after the staff finds the placement cabinet where the EPON OLT optical fiber device body is located, because in the prior art, in order to save space, a plurality of EPON OLT optical fiber device bodies are usually placed in a placement cabinet, which causes the staff to distinguish which of the multiple EPON OLT optical fiber device bodies in the placement cabinet is faulty. Although the alarm device can give the staff certain prompts, it is still not very obvious. The setting of the pushing device and the limiting device solves this technical problem. When the EPON OLT optical fiber device body fails and alarms, the limiting motor on the partition plate where it is located will receive the signal of the alarm device, so that the output end of the limiting motor rotates, so that the limiting plate no longer blocks the push-back spring. After the push-back spring loses the restriction of the limiting plate, it pushes the EPON OLT optical fiber device body toward the outside of the placement cabinet, so that a part of the EPON OLT optical fiber device body leaks out of the placement cabinet, so that after the cabinet door is opened, the faulty EPON A part of the OLT optical fiber device body will also be pushed out, so that the staff can accurately find the faulty EPON OLT optical fiber device body, and the EPON OLT optical fiber device body pushed out and placed outside the cabinet is also convenient for the staff to repair.
[0014] Furthermore, the pushing device also includes a push back plate located between the end face of the EPON OLT optical fiber equipment body away from the opening and the push back spring, one side of the push back plate abuts against the EPON OLT optical fiber equipment body, and the other side is fixedly connected to the push back spring, a limiting opening is provided at the upper end of the push back plate, and the limiting plate extends into the rebound plate through the limiting opening.
[0015] By adopting the above technical scheme, although the setting of the limit device and the pushing device can make the faulty EPONOLT fiber optic device body be pushed out of the cabinet for the convenience of staff to inspect and repair, after the staff completes the inspection, the staff must first push the push-back spring to contract and then control the limit motor to rotate so that the limit plate blocks the push-back spring before the inspected EPON OLT fiber optic device body can be placed on the partition board, which is very troublesome. The setting of the push-back plate solves this technical problem. The setting of the push-back plate enables the staff to only place the EPON OLT fiber optic device body on the partition board after the inspection is completed, and then push the EPON OLT fiber optic device body to compress the push-back spring to contract and align the limit port with the limit plate, and then the staff starts the limit motor to rotate so that the limit plate can be reinserted into the push-back plate, thereby improving the staff's usage experience.
[0016] Furthermore, a plurality of balls are evenly distributed on the partition plate, and the plurality of balls are rotatably connected to the partition plate.
[0017] By adopting the above technical solution, although the setting of the push-back plate makes it more convenient for the staff to place the EPON OLT optical fiber device body, the push-back spring pushes the EPON OLT optical fiber device body through the push-back plate, which will cause the distance of pushing the EPON OLT optical fiber device body to be shortened, resulting in the staff having to pull the EPON OLT optical fiber device body to move a certain distance outside the placement cabinet before they can repair the EPON OLT optical fiber device body during maintenance, which is very inconvenient. The setting of the ball solves this technical problem. Through the setting of the ball, when the push-back spring pushes the EPON OLT optical fiber device body to move outside the placement cabinet through the push-back plate, the EPON OLT optical fiber device body during the movement will drive the ball to rotate, and the rotating ball provides a certain power for the EPON OLT optical fiber device body to move outward, thereby making the EPON OLT optical fiber device body move a longer distance outside the placement cabinet, so that the staff can repair it without pulling the EPON OLT optical fiber device body, which is very convenient.
[0018] Furthermore, the EPON OLT optical fiber device body is provided with limiting pieces on both sides away from the opening end, and the EPON OLT optical fiber device body is provided with limiting structures on both sides close to the opening end.
[0019] Furthermore, the limiting structure includes a storage opening opened on the inner side of the storage cabinet, a limiting block located in the storage opening, and a limiting spring located between the limiting block and the storage opening, one end of the limiting spring is fixedly connected to the limiting block, and the other end is fixedly connected to a surface of the storage opening away from the limiting block.
[0020] By adopting the above technical scheme, although the setting of the ball makes it more convenient for the staff to inspect the EPON OLT optical fiber device body, it also causes the push-back spring to push the EPON OLT optical fiber device body to move outside the placement cabinet, and the EPON OLT optical fiber device body may directly slide out of the placement cabinet and fall on the ground, causing the EPON OLT optical fiber device body to be damaged. The setting of the limiting structure and the limiting piece has solved this technical problem. Through the setting of the limiting piece, when the EPON OLT optical fiber device body is pushed by the push-back spring to slide out of the placement cabinet, the limiting piece will contact the limiting block, and the limiting block blocks the limiting piece to prevent the EPON OLT optical fiber device body from sliding out of the placement cabinet, so that the EPON OLT optical fiber device body can be prevented from being damaged, and when the EPON OLT optical fiber device body is placed in the placement cabinet, it is only necessary to push the limiting block to compress the limiting spring and retract it into the receiving port, so that the EPON OLT optical fiber device body can be placed in the placement cabinet.
[0021] Furthermore, an arc portion is provided at one end of the limit block close to the opening.
[0022] By adopting the above technical solution, the circular arc portion allows the staff to place the EPON OLT optical fiber device body without having to push the limit block to retract into the storage port. They only need to align the limit pieces on both sides of the EPON OLT optical fiber device body with the circular arc portion, and then push the EPON OLT optical fiber device body to make the limit pieces rub against the circular arc portion to compress the limit blocks, thereby making it more convenient for the staff to place the EPON OLT optical fiber device body.
[0023] Furthermore, a reset switch electrically connected to a self-locking motor is provided at the outer bottom end of the placement shell.
[0024] By adopting the above technical solution, the reset switch is used to start the self-locking motor when the staff closes the cabinet door after completing the maintenance, so that the self-locking rod is re-located in the insertion gap to lock the cabinet door.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. By setting the self-locking device, when the cabinet door is in a closed state, the self-locking rod extends into the plug-in notch to clamp the plug-in piece, thereby preventing the rebound tension spring from pulling the cabinet door open. When the alarm device detects a fault in the EPON OLT optical fiber device body, it sends an alarm and a start signal to the self-locking device at the same time. The self-locking device receives the start signal, and the self-locking motor rotates to disengage the self-locking rod from the plug-in notch. At this time, the plug-in piece is not restricted, resulting in the cabinet door being pulled open by the rebound tension spring. In this way, when the staff follows the alarm sound, it can be easily observed that the cabinet door of one of the multiple placement cabinets is open, so that the staff can quickly find the placement cabinet where the faulty EPON OLT optical fiber device body is located, thereby saving the staff's time in finding the placement cabinet, saving the staff's workload and improving the staff's work efficiency.
[0027] 2. Through the arrangement of the limit device and the pushing device, it is achieved that when the EPON OLT optical fiber device body fails and alarms, the limit motor on the partition plate where it is located will receive the signal of the alarm device, so that the output end of the limit motor rotates, so that the limit plate is separated from the push-back plate, and at this time the push-back spring pushes the push-back plate so that the push-back plate pushes the EPON OLT optical fiber device body to move outside the placement cabinet, so that a part of the EPON OLT optical fiber device body leaks out of the placement cabinet, so that after the cabinet door is opened, a part of the faulty EPON OLT optical fiber device body will also be pushed out, so that the staff can accurately find the faulty EPON OLT optical fiber device body, and the EPON OLT optical fiber device body pushed out of the placement cabinet is also convenient for the staff to overhaul.
[0028] 3. Through the setting of the limiting structure, it is achieved that when the EPON OLT optical fiber device body is pushed by the push-back spring to slide out of the placement cabinet, the limiting plate will contact the limiting block, and the limiting block blocks the limiting plate to prevent the EPON OLT optical fiber device body from sliding out of the placement cabinet, thereby preventing the EPON OLT optical fiber device body from being damaged. When placing the EPON OLT optical fiber device body in the placement cabinet, it is only necessary to push the limiting block to compress the limiting spring and retract it into the receiving port, so that the EPON OLT optical fiber device body can be placed in the placement cabinet.

[0037] The present application is further described in detail below in conjunction with the accompanying drawings.
[0038] Example, see Figure 1 , Figure 2 , Figure 3, an OLT optical fiber fault warning and positioning device in an EPON network, comprising an EPONOLT optical fiber device body 1, a placement cabinet 2 for placing the EPON OLT optical fiber device body 1, and an alarm device 10 installed on the EPON OLT optical fiber device body 1, an opening 20 is provided on one side of the placement cabinet 2, two opposite fixing plates 21 are provided on one side of the opening 20, the two fixing plates 21 are respectively arranged at the upper and lower ends of the placement cabinet 2, a cabinet door 3 rotatably connected to the fixing plates 21 is provided between the two fixing plates 21, a rebound tension spring 22 is provided between the cabinet door 3 and the outer side of the placement cabinet 2, one end of the rebound tension spring 22 is fixedly connected to the outer side of the placement cabinet 2, and the other end is fixedly connected to the outer side of the cabinet door 3, a plug-in sheet 30 is provided on the inner side of the cabinet door 3, and a side of the opening 20 away from the cabinet door 3 is provided There is a plug-in interface 23, and a self-locking device 4 for signal connection alarm device 10 is provided on one side of the plug-in interface 23. The self-locking device 4 includes a placement shell 40 located on one side of the plug-in interface 23, a self-locking motor 41 located in the placement shell 40 and fixedly connected to the placement shell 40, and a self-locking rod 42 fixedly connected to the output end of the self-locking motor 41. A plug-in notch 31 is provided on one side of the plug-in plate 30 for the self-locking rod 42 to extend into. The plug-in notch 31 runs through the upper and lower ends of the plug-in plate 30. The placement shell 40 is fixedly connected to the placement cabinet 2 and one side adjacent to the plug-in interface 23 is connected to the plug-in interface 23.
[0039] When the cabinet door 3 is in a closed state, the self-locking rod 42 extends into the plug-in notch 31 to clamp the plug-in piece 30, thereby preventing the rebound tension spring 22 from pulling the cabinet door 3 open. When the alarm device 10 detects a fault in the EPON OLT optical fiber device body 1, it sends an alarm and a start signal to the self-locking device 4. The self-locking device 4 receives the start signal, and the self-locking motor 41 rotates to disengage the self-locking rod 42 from the plug-in notch 31. At this time, the plug-in piece 30 is not restricted, causing the cabinet door 3 to be pulled open by the rebound tension spring 22. In this way, when the staff follows the alarm sound to find it, it can be easily observed that the cabinet door 3 of one of the multiple cabinets 2 is open, so that the staff can quickly find the faulty EPON The OLT optical fiber equipment body 1 is located in the placement cabinet 2, which saves the staff's time in looking for the placement cabinet 2, saves the staff's workload and improves the staff's work efficiency, and a reset switch 43 electrically connected to the self-locking motor 41 is provided at the bottom of the outer side of the placement shell 40. The reset switch 43 is used to start the self-locking motor 41 through the reset switch 43 when the staff closes the cabinet door 3 after the maintenance is completed, so that the self-locking rod 42 is re-positioned in the insertion notch 31 to clamp the cabinet door 3.
[0040] Although the setting of the self-locking device 4 can make the cabinet door 3 of the placement cabinet 2 where the EPON OLT optical fiber device body 1 is located open when it fails, it is convenient for the staff to find the faulty EPON OLT optical fiber device body 1. However, after the staff finds the placement cabinet 2 where the EPON OLT optical fiber device body 1 is located, because in the prior art, multiple EPON OLT optical fiber device bodies 1 are usually placed in one placement cabinet 2 in order to save space, the staff still needs to distinguish which of the multiple EPON OLT optical fiber device bodies 1 in the placement cabinet 2 is the faulty one. Although the alarm device 10 can give the staff certain prompts, it is still not very obvious. In order to solve this technical problem, referring to Figure 4 , Figure 5 In this embodiment, a plurality of partition plates 24 are arranged in the storage cabinet 2, and the plurality of partition plates 24 are arranged in a linear array along the height direction of the storage cabinet 2 and a gap is left between the plurality of partition plates 24. A pushing device 5 and a limiting device 6 are provided on the end of the upper surface of each partition plate 24 away from the opening 20. The limiting device 6 includes a limiting motor 60 fixedly connected to the storage cabinet 2 and a limiting plate 61 fixedly connected to the peripheral surface of the output end of the limiting motor 60. The pushing device 5 includes a push-back spring 50, one end of the push-back spring 50 is fixedly connected to the inner wall of the storage cabinet 2, and the other end is fixedly abutted against the limiting plate 61. A side of the limiting plate 61 away from the push-back spring 50 faces the end face of the EPON OLT optical fiber device body 1 away from the opening 20. The signal of the limiting motor 60 is connected to the alarm device 10. When wiring, the wiring operator needs to reserve elastic space for the line of the EPON OLT optical fiber device body 1. When the EPON After the OLT optical fiber device body 1 fails and alarms, the limit motor 60 on the partition plate 24 where it is located will receive the signal of the alarm device 10, causing the output end of the limit motor 60 to rotate, so that the limit plate 61 no longer blocks the push-back spring 50. After the push-back spring 50 loses the restriction of the limit plate 61, it pushes the EPON OLT optical fiber device body 1 toward the placement cabinet 2, so that a part of the EPON OLT optical fiber device body 1 leaks out of the placement cabinet 2, so that after the cabinet door 3 is opened, a part of the faulty EPON OLT optical fiber device body 1 will also be pushed out, so that the staff can accurately find the faulty EPON OLT optical fiber device body 1, and the EPON OLT optical fiber device body 1 pushed out of the placement cabinet 2 is also convenient for the staff to repair.
[0041] Although the setting of the limiting device 6 and the pushing device 5 can make the faulty EPON OLT optical fiber device body 1 be pushed out of the placement cabinet 2 for easy maintenance by the staff, after the staff completes the maintenance, the staff must first push the push-back spring 50 to contract and then control the limiting motor 60 to rotate so that the limiting plate 61 blocks the push-back spring 50 before the EPON OLT optical fiber device body 1 that has been repaired can be placed on the partition plate 24, which is very troublesome. In order to solve this technical problem, in this embodiment, the pushing device 5 is set to also include a push-back plate 51 located between the end face of the EPON OLT optical fiber device body 1 away from the opening 20 and the push-back spring 50. One side of the push-back plate 51 abuts against the EPON OLT optical fiber device body 1, and the other side is fixedly connected to the push-back spring 50. A limiting opening 52 is provided at the upper end of the push-back plate 51, and the limiting plate 61 extends into the rebound plate through the limiting opening 52. The setting of the push-back plate 51 enables the staff to place the EPON OLT optical fiber device body 1 on the partition plate 24 after the maintenance is completed, and then push the EPON The OLT optical fiber device body 1 compresses the push-back spring 50 to contract and aligns the limit opening 52 with the limit plate 61 , and then the staff starts the limit motor 60 to rotate so that the limit plate 61 is reinserted into the push-back plate 51 , thereby improving the staff's user experience.
[0042] 2, the EPON OLT optical fiber device body 1 is pushed out of the cabinet 2 by the push-back spring 50, and the EPON OLT optical fiber device body 1 is pushed out of the cabinet 2 by the push-back spring 50. The OLT optical fiber equipment body 1 can be easily inspected and repaired.
[0043] Although the setting of the ball bearing 25 makes it more convenient for the staff to inspect the EPON OLT optical fiber device body 1, it also causes the push-back spring 50 to push the EPON OLT optical fiber device body 1 to move outside the placement cabinet 2. The EPON OLT optical fiber device body 1 may directly slide out of the placement cabinet 2 and fall on the ground, causing the EPON OLT optical fiber device body 1 to be damaged. In order to solve this technical problem, refer to Figure 6 ,、 Figure 7 In this embodiment, the EPON OLT optical fiber device body 1 is provided with limiting pieces 11 on both sides of the end away from the opening 20, and the EPON OLT optical fiber device body 1 is provided with limiting structures 7 on both sides of the end close to the opening 20. The limiting structure 7 includes a storage port 70 opened on the inner side of the storage cabinet 2, a limiting block 71 located in the storage port 70, and a limiting spring 72 located between the limiting block 71 and the storage port 70. One end of the limiting spring 72 is fixedly connected to the limiting block 71, and the other end is fixedly connected to the side of the storage port 70 away from the limiting block 71. Through the setting of the limiting piece 11, when the EPON OLT optical fiber device body 1 is pushed by the push-back spring 50 to slide out of the storage cabinet 2, the limiting piece 11 will contact the limiting block 71, and the limiting block 71 blocks the limiting piece 11 to prevent the EPON OLT optical fiber device body 1 from sliding out of the storage cabinet 2, so that the EPON OLT optical fiber device body 1 can be prevented from being damaged, and the EPON OLT optical fiber device body 1 can be placed. When the OLT optical fiber device body 1 is placed in the cabinet 2 , it is only necessary to push the limit block 71 to compress the limit spring 72 and retract it into the receiving opening 70 , so that the EPON OLT optical fiber device body 1 can be placed in the cabinet 2 .
[0044] Although the setting of the limiting structure 7 can prevent the EPON OLT optical fiber device body 1 from sliding out of the placement cabinet 2, when the EPON OLT optical fiber device body 1 is placed in the placement cabinet 2, it is necessary to first push the limiting block 71 to compress the limiting spring 72 and retract it into the receiving port 70, which causes the staff to place the EPON OLT optical fiber device body 1. It is relatively troublesome. In order to solve this technical problem, the present embodiment is provided with an arc portion 73 at one end of the limiting block 71 close to the opening 20. The arc portion 73 makes it unnecessary for the staff to push the limiting block 71 to retract into the receiving port 70 when placing the EPON OLT optical fiber device body 1. It is only necessary to align the limiting pieces 11 on both sides of the EPON OLT optical fiber device body 1 with the arc portion 73, and then push the EPON OLT optical fiber device body 1 so that the limiting piece 11 rubs against the arc portion 73 to compress the limiting block 71, thereby making it more convenient for the staff to place the EPON OLT optical fiber device body 1.
