Description

Technical Field

[0001] The invention belongs to the technical field of interface switching, and in particular relates to a terahertz wave propagation characteristic detection system in an electric power polymer composite material and a detection method thereof. Background Art

[0002] In optical communication systems, wavelength division matrix is ​​a device used for wavelength division multiplexing and wavelength demultiplexing. It can select and route optical signals of different wavelengths according to needs. In optical cross-connection networks, MEMS optical switches are currently used to achieve flexible routing and switching of optical signals of different wavelengths. Compared with traditional mechanical optical switches, MEMS optical switches have the advantages of low insertion loss, low crosstalk, low polarization sensitivity, high extinction ratio, high switching speed of waveguide switches, small size, and easy large-scale integration to meet the technical requirements of DWDM all-optical networks. The principle of MEMS optical switches is very simple. When performing optical switching, the angle of the MEMS micromirror is moved or changed by electrostatic force or magnetic force, and the input light is switched to different output ends of the optical switch to achieve switching and on-off of the optical path.

[0003] In the prior art, MEMS optical switches usually have a backup interface. In the case of a main interface failure, maintenance and upgrade, load balancing and disaster recovery, the backup interface will be switched to use. In order to improve the security, reliability and maintenance efficiency of the system, as well as the aesthetics and user experience of the equipment, the MEMS optical switch backup interface is usually designed to be hidden, so that the existence of the backup interface is almost not exposed when the network is working normally. When it is necessary to switch the backup interface, a mechanical arm type automation device is generally used to ensure the efficiency and accuracy of replacing the MEMS optical switch backup interface and reduce equipment loss. However, the mechanical arm is usually equipped with a precision sensor for detecting and adjusting the alignment position, and the operating cost is relatively high. At the same time, the electrical signal controlling the mechanical arm is susceptible to electromagnetic interference, and there may be signal attenuation in high-speed data transmission, which may cause the mechanical arm to have a response delay or erroneous operation problem.

[0004] In addition, the backup interface of existing MEMS optical switches is usually not concealed, so it is easy for illegal personnel to illegally plug in external connectors. During the plugging and unplugging process, the network connection signal of the main interface may become unstable due to the switching connection between the network and the optical fiber, thereby causing the unreliability of the original communication.

[0005] In view of this, the present invention proposes a hidden standby interface switching device for an optical cross-connection network based on a wavelength division matrix to make up for and improve the deficiencies of the prior art. Summary of the invention

[0017] Compared with the prior art, the beneficial effects are:

[0018] 1. When switching interfaces, the auxiliary switching mechanism is used, and a mobile frame is used to cooperate with a docking column and a pair of worms for docking. If the end of the worm is docked with the first gear, the collimating lens can be plugged in and out. If the end of the worm is docked with the pulley, the collimating lens can be moved between the main interface and the spare interface. The auxiliary switching of the hidden spare interface can make the plugging and unplugging force uniform and the plugging and unplugging trajectory smooth, so as to achieve a mechanical plugging and unplugging effect, avoid the use of a sensor robot arm, and reduce production costs. In addition, the moving speed of the collimating lens can be arbitrarily controlled by hand-crank drive, and it can be stopped at any time, thereby reducing the friction loss between the TO tube cap and the collimating lens, or the network or equipment failure can be stopped in time during the switching, so as to prevent the signal attenuation phenomenon that may exist in high-speed data transmission, thereby causing the robot arm to have a response delay or wrong operation problem. There is no need to worry about signal interference through hand-crank drive, and the accuracy of plugging and unplugging control is guaranteed;

[0019] 2. Through the setting of the rubber head hook and the anti-skid groove, the rubber head hook uses its curved hook shape to generate an inward grip when the worm is squeezed, and the anti-skid groove matched with the size of the rubber head of the rubber head hook can ensure the anti-slip property of the clamping connection. In addition, the clamping limit of the telescopic column and the support plate makes the connection between the worm and the docking column stable, and the anti-skid groove is in the shape of an inner concave ring and has a plurality of transverse grooves equidistantly arranged inside, so that the rubber head hook can be increased in friction by the plurality of transverse grooves when rotating, further enhancing the stability of docking. There are also a pair of pulleys and the first gear, so that the two worms always keep the same speed regardless of the direction of rotation in the same direction or in the opposite direction, so that the rectangular slide is evenly stressed and moves smoothly, thereby keeping the moving trajectory of the collimating lens plug-in and switch in a horizontal line, increasing the accuracy of interface switching;

[0020] 3. By setting the protective shell in the protective hiding mechanism, the door handle of the first plugboard is set at the top corner of the first plugboard, and the door handle is located inside the protective shell, forming the first layer of protection. Even if the first plugboard is moved away or violently damaged, the I-shaped lock block in the spare pipe cap can prevent the connector from being inserted, forming the second layer of protection. The spare pipe cap with double hidden protection can effectively prevent illegal personnel from illegally plugging in external connectors, thereby ensuring the stable operation of the network;

[0021] 4. Through the setting of the I-shaped lock block and the lock rod, after the operator opens the protective shell, he needs to push the pressing plate to take out the lock rod. The internal lock rod cannot be observed from the outside. The hidden nature of the lock rod, combined with the setting of the weight of the side of the I-shaped lock block away from the lock hole being greater than the side close to the lock hole, can make it difficult for illegal personnel to pull out the I-shaped lock block with bare hands, further increasing the difficulty of using the spare pipe cap, thereby improving the reliability of the original communication.

[0050] Further examples:

[0051] Please refer to Figure 1 , Figure 3 , Figures 10 to 13 As shown,

[0052] The protective hiding mechanism 7 includes a protective shell 71 fixedly connected to the outer wall of the optical switch body 1, a second plugboard 75 is slidably connected to the top of the protective shell 71, a first plugboard 74 is slidably connected to the inner wall of the protective shell 71 away from the optical switch body 1, a pair of door handles 76 are fixedly connected at the top corner of the first plugboard 74, and the door handles 76 are located inside the protective shell 71, a pair of positioning columns 73 are fixedly connected to the outer wall of the protective shell 71, and a pair of positioning columns 73 are also fixedly connected to the outer wall of the TO tube cap 2;

[0053] The protective hiding mechanism 7 also includes a spare pipe cap 77 located inside one side of the protective shell 71, and the spare pipe cap 77 is fixedly connected to the inner wall of the optical switch body 1 on one side away from the protective shell 71, and the inner wall on the other side of the protective shell 71 is rotatably connected to a pressing plate 72, and a pair of third springs 710 are fixedly connected to the bottom of the pressing plate 72, and one end of the pair of third springs 710 away from the pressing plate 72 is fixedly connected to the inner wall of the protective shell 71, and a clamping seat 712 is fixedly connected to the side of the bottom of the protective shell 71 away from the third spring 710, and a locking rod 711 is clamped on the top of the clamping seat 712;

[0054] The protection and hiding mechanism 7 also includes an I-shaped lock block 78 that is clamped to the inner wall of the spare pipe cap 77. A lock hole 79 that matches the lock rod 711 is formed on one side of the I-shaped lock block 78 that is close to the protection shell 71.

[0055] Among them: two pairs of positioning columns 73 are arranged diagonally, and the inner wall tangent points of each pair of positioning columns 73 are respectively located on the inner diameters of the spare pipe cap 77 and the TO pipe cap 2, and can form a ninety-degree angle with the axis of the spare pipe cap 77 and the TO pipe cap 2 respectively.

[0056] The effects achieved by this embodiment are as follows: In the prior art, the spare interface of the MEMS optical switch is usually not concealed, so it is easy for illegal personnel to illegally or illegally plug in the external connector, thereby causing the unreliability of the original communication. Compared with the prior art, through the implementation of this embodiment, the protection and hiding mechanism 7 is set to set the first plug plate 74 of the protective shell 71 switch as a hidden switch, and the spare pipe cap 77 is locked by the I-shaped lock block 78. The double hidden protection spare pipe cap 77 can effectively prevent illegal personnel from illegally or illegally plugging in the external connector.

[0057] Working principle:

[0058] In the initial state: the collimating lens 4 is inserted into the TO tube cap 2, the double-layer clamp 614 is in a clamping state, both sides of the worm 66 are in an unconnected state, the second spring 622, the first spring 620 and the third spring 710 are all in a naturally relaxed state, and the locking rod 711 is located on the clamping seat 712.

[0059] When in use, the operator first pushes the movable frame 61 toward the protective shell 71, so that the first gear 63 and the docking column 610 are close to the rotating shaft of the worm 66 until the worm 66 is inserted into the docking column 610. When the worm 66 moves on the inner wall of the docking column 610, the rubber head hook 621 will be squeezed and rotated. At this time, the second spring 622 changes from an initial state to a stretched state. After the rubber head hook 621 rotates, the rubber head will be clamped in the position of the anti-skid groove 623. The friction force is increased by the anti-skid groove 623 and the rubber head of the rubber head hook 621. With the inward gripping force of the curved hook 621 itself, the end of the worm 66 can be firmly clamped. At the same time, the movable frame 61 moves toward the protective shell 71, which will also drive the first limit rod 612 to move on the support plate When the telescopic column 619 contracts, the first spring 620 will change from an initial state to a compressed state. When the telescopic column 619 moves to the inner wall of the support plate 611, the telescopic column 619 can be popped out and connected to the card slot on the inner wall of the support plate 611 through the elastic force of the first spring 620. The joint action of multiple telescopic columns 619 can limit the position of the first limit rod 612, so that the support plate 611 can be fixed after it moves into place. If there is a concern that the limiting force is not enough, the operator can pinch the outer wall of the support plate 611 and the movable frame 61 to fix them. At this time, the operator turns the rotating rod handle 62 to drive the near The first gear 63 of the optical switch body 1 rotates clockwise, and under the meshing action of the first gear 63, the first gear 63 away from the optical switch body 1 will rotate counterclockwise, and the pair of worms 66 connected to the two first gears 63 will also rotate synchronously, and then through the meshing action of the worm 66, the worm wheel 68 will rotate counterclockwise from a top view. The arrangement of the pair of first gears 63 can make the rotation speed of the pair of worms 66 the same, so as to ensure the rotation stability of the worm wheel 68. When the worm wheel 68 rotates, the second gear 65 on the top is driven by the connecting rod 67 to rotate counterclockwise as well, and then the second gear 65 is meshed with the rack 616, so that the rectangular slide 64 moves synchronously with the rack 616 in the direction away from the optical switch body 1. A double-layer clamping block 614 is slidably connected to the top of the slide 64, and each layer of the double-layer clamping block 614 is respectively clamped on the outer wall of the multi-fiber plug pin 3 and the collimating lens 4 to ensure the stability of clamping. Therefore, the multi-fiber plug pin 3 and the collimating lens 4 will move in the direction away from the optical switch body 1 along with the movement of the rectangular slide 64, that is, the collimating lens 4 will be pulled out from the inner wall of the TO tube cap 2. Under the support of the support plate 611 and the multi-stage meshing action, the rectangular slide 64 is evenly stressed and moves smoothly, so that the movement trajectory of the collimating lens 4 pulled out of the TO tube cap 2 remains in a straight line. Similarly, the operator can rotate the rotating rod handle 62 in the opposite direction to smoothly insert the collimating lens 4 into the TO tube cap 2, so that the rectangular slide 64 can reciprocate to any position along the U-shaped frame 618.Since the transmission response between the structures is usually relatively timely, the operator can move and plug in the collimating lens 4 almost instantly after turning the rotating rod handle 62, which does not take a long time;

[0060] Furthermore, when it is necessary to switch the backup interface, the collimating lens 4 that has been inserted into the main interface can be pulled out through the above steps, and then the operator needs to change the docking direction of the mobile frame 61, that is, push the mobile frame 61 to move in the direction of the TO tube cap 2, so that the pulley 617 and the corresponding docking column 610 move in the direction of the worm 66. Similarly to the above steps, the worm 66 can be stably engaged with the side away from the first gear 63 through the limiting action of the telescopic column 619 on the same side and the rubber head hook 621 and the anti-slip groove 623. At this time, the operator rotates the pulley counterclockwise The rotating handle 62 on 617 can make the two pulleys 617 rotate counterclockwise synchronously under the friction force of the frosted belt 69, so that the pair of worms 66 rotate in the same direction, while the worm wheel 68 meshed with the inner side of the worm 66 will not rotate because the two sides rotate in the same direction. However, under the action of the spiral groove of the worm 66 itself, the worm wheel 68 will move along the groove of the worm 66 toward the protective shell 71. Similarly, the operator can rotate the rotating handle 62 in the opposite direction to move the worm wheel 68 toward the TO tube cap 2, so that the worm wheel 68 can move along the worm 66. 6 reciprocates to any position, and all structures above the worm gear 68 will move synchronously, that is, the collimating lens 4 will also move toward the direction of the protective shell 71 until it abuts against the positioning column 73. Since the inner wall tangent point of the two positioning columns 73 is located on the inner diameter of the spare pipe cap 77 and can form a 90-degree angle with the axis of the spare pipe cap 77, the outer wall of the collimating lens 4 can be simultaneously attached to the outer walls of the two positioning columns 73, so that the outer diameter of the collimating lens 4 coincides with the inner diameter trajectory of the spare pipe cap 77. The operator changes the direction of the moving frame 61 again and rotates the rotating rod counterclockwise. The handle 62 can insert the collimating lens 4 into the inner wall of the spare tube cap 77 to complete the switch from the main interface to the spare interface. The operator can change the position of the moving frame 61. If the end of the worm 66 is docked with the first gear 63, the collimating lens 4 can be plugged in and out. If the end of the worm 66 is docked with the pulley 617, the collimating lens 4 can be moved between the main interface and the spare interface. The moving speed of the collimating lens 4 can be arbitrarily controlled by the hand-crank drive, thereby reducing the friction loss between the TO tube cap 2 and the collimating lens 4. The hand-crank drive can also ensure the accuracy of the plug-in and pull-out control.

[0061] Please refer to the above working process Figures 1 to 9 , Fig.11 .

[0062] Furthermore, in a normal state, the spare interface is buried in the inner wall of the optical switch body 1, the spare pipe cap 77 of the spare interface extends to the outer wall of the optical switch body 1, and the spare pipe cap 77 is covered with a protective shell 71 for protection. At the same time, the second plugboard 75 and the first plugboard 74 are both in a closed state, which can prevent dust and moisture, and also prevent the spare pipe cap 77 from being exposed to the outside and illegally plugged and unplugged. By setting the door handle 76 at the top corner of the first plugboard 74 and the whole being located inside the protective shell 71, if When the criminal opens the second plug plate 75, he can only see the outer wall of the spare pipe cap 77 and cannot insert the external joint. It is also difficult to find the door handle 76 from the outside. It takes time to slowly move the first plug plate 74 to open it, forming a first layer of protection. Even if the first plug plate 74 is moved away or violently damaged to expose the spare pipe cap 77, the I-shaped lock block 78 in the spare pipe cap 77 can prevent the joint from being inserted, and the side of the I-shaped lock block 78 away from the lock hole 79 is set with a weight greater than that of the side near the lock hole 79. The locking rod 711 is located on the side close to the locking hole 79, so it is difficult to pull out the I-shaped locking block 78 by hand without the locking rod 711 or a special tool, forming a second layer of protection, so that it is difficult for lawless elements to illegally and illegally plug and unplug the spare interface. If the operator needs to pull out the I-shaped locking block 78, he can directly press the side of the pressing plate 72 away from the third spring 710, then reach out to take the locking rod 711 from the clamping seat 712, and insert one side of the hemispherical block of the locking rod 711 into the locking hole 79 first, until the hemispherical block of the locking rod 711 is locked under the action of gravity. The locking rod 711 is clamped on the inner wall of the I-shaped locking block 78. The operator then pulls the pull ring of the locking rod 711 to remove the I-shaped locking block 78, and the operation of switching the standby interface can be performed. After using the locking rod 711, the pressing plate 72 is pressed again to put the locking rod 711 back to its original position. The pressing plate 72 is restored to a horizontal state by the elastic force of the third spring 710. The locking rod 711 inside cannot be observed from the outside, so that the locking rod 711 can also be hidden. In addition, the standby pipe cap 77 with double hidden protection can effectively ensure the stable operation of the network.
