Description

Technical Field

[0001] The present invention relates to the technical field of plate surface treatment, in particular to a communication optical cable fault locating device and method based on computer technology. Background Art

[0002] Optical cable is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. Optical cable is mainly composed of optical fiber, plastic protective sleeve and plastic outer skin. Optical cable is a certain number of optical fibers that form a cable core in a certain way, covered with a sheath, and some are also covered with an outer sheath. When the optical signal is converted into an optical pulse and injected into the optical fiber through the light source at the transmitting end, the optical signal is transmitted in the fiber core by total internal reflection. The working principle of the optical time domain reflectometer - OTDR is based on the time domain reflection characteristics of light. It determines the abnormal points in the optical fiber by emitting a series of short pulse optical signals to the optical fiber, and analyzing the time delay and intensity change of the reflected optical signal through the computer processor.

[0003] The patent application number CN113098599A discloses a distribution network communication optical cable fault location device, including a traveling frame, a traveling mechanism, a wheel assembly, a knocking mechanism, a driving motor, a wireless remote control mechanism and a clamping assembly. The present invention places the detector host at the beginning of the overhead cable, clamps the handheld terminal in two clamping assemblies, and sets up two traveling mechanisms on the outside of the overhead cable. The wireless remote control mechanism on the traveling frame remotely controls the operation of the driving motor, so that the driving motor drives the wheel assembly, and then the wheel assembly drives the traveling mechanism engaged with it to move along the outside of the overhead cable; at the same time, when the device is in the process of walking, the power of walking drives the knocking mechanism to knock back and forth, thereby realizing the transmission of vibration energy, and then adopts a detection method similar to that of buried cables to locate the fault of the overhead cable.

[0004] This patent can indeed drive the wheel assembly by driving the motor, and then the wheel assembly drives the walking mechanism engaged with it to move along the outside of the overhead cable. During the walking process, the power of the walking drives the knocking mechanism to knock back and forth to locate the fault. However, the way the device fixes the optical cable is relatively conventional. When the optical cable is bent or the device is subject to wind resistance, it is easy to cause secondary damage to the optical cable. In addition, the vibration detection method is easily disturbed by the external environment, and its positioning accuracy still needs to be improved. Summary of the invention

[0015] On the other hand, the present invention also provides a method for locating a communication optical cable fault based on computer technology, using the above-mentioned communication optical cable fault locating device based on computer technology, comprising the following steps: S1. First, connect an optical time domain reflectometer (OTDR) to one end of the faulty optical cable. The instrument calculates the location of the optical cable fault by emitting a light source and receiving reflected light. Then, remove the OTDR. S2. Then, by estimating the distance to the optical cable overhead pole closest to the fault location, the worker sets up a ladder and climbs to the height where the faulty optical cable is located, takes out the device and ensures that the airbags on both sides are filled with an appropriate amount of helium, separates the right half shell and the left half shell at the hinge, and clamps the optical cable between the two pressing wheels; S3, then, tighten the limit elastic belt on the right side forward and fix it through the limit pin, so that the turntable on the right side rotates, thereby driving the pressing wheel to press the optical cable; S4, then, insert the pull pin and ensure that the pull elastic band is in a relaxed state; S5, pull the optical cable outside the two pressing wheels into the space between the corresponding lower ball wheel and upper ball wheel, and then align the right half shell and the left half shell to ensure that the lower ball wheel and the upper ball wheel on the left and right sides clamp the optical cable correspondingly; S6.

After tying the rubber band, connect a red light emitter to one end of the faulty optical cable to emit red light, and start the double-headed motor, so that the two pressing wheels in the driving device rotate in opposite directions and slide forward along the optical cable sandwiched therebetween; S8. When the red light detection head detects the red light, the integrated controller controls the double-headed motor to reverse so that the device slides back. At this time, the upper ball wheel at the front also changes its rotation direction, so that the ratchet can mesh with the inner ratchet to rotate, so that the flat gear rotates coaxially, the rack slides backward to pull the pull rope, and then the rubber band is released to cover the fault location; S9. Subsequently, the device continues to slide back along the optical cable to the starting point, and the worker needs to remove it from the optical cable.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The communication optical cable fault locating device and method based on computer technology can slide along the overhead suspended optical cable when locating the faulty optical cable. The pressing wheel presses the optical cable to bend it and fully expose the broken part of the optical cable, so that the red light detection head can more easily receive the red light at the faulty broken part, thereby realizing the accurate positioning of the faulty broken part efficiently and conveniently without removing the optical cable, reducing the situation where workers mistakenly remove the normal optical cable due to inaccurate positioning, and improving the efficiency and accuracy of locating the faulty broken part.

[0017] 2. The communication optical cable fault location device and method based on computer technology, when the broken fault is detected, the upper ball wheel in front changes the direction of rotation, so that the ratchet can mesh with the inner ratchet to rotate, so that the flat gear rotates coaxially, the rack slides backward to pull the pull rope, and the pull rope drives the L-shaped slide bar to disengage from the buckle, and then releases the rubber band on the hook petal through the above series of mechanical structures to wrap around the fault. Therefore, after the device is installed and started, the entire fault location process can be completed without remote control, which is efficient, convenient and stable.

Then, by estimating the distance to the optical cable overhead pole closest to the fault location, the worker sets up a ladder and climbs to the height where the faulty optical cable is located, takes out the device and ensures that the air bags (13) on both sides are filled with an appropriate amount of helium, separates the right half shell (11) and the left half shell (12) at the hinge, and clamps the optical cable between the two pressing wheels (23); S3, then, the right-side limiting elastic band (201) is pulled forward and fixed by the limiting latch (202), so that the right-side rotating disk (20) rotates, thereby driving the pressing wheel (23) to press the optical cable; S4, then, insert the pull pin (212) and ensure that the pull elastic band (211) is in a relaxed state; S5, pull the optical cable outside the two pressing wheels (23) into between the corresponding lower ball wheel (31) and upper ball wheel (32), and then align the right half shell (11) and the left half shell (12) to ensure that the lower ball wheel (31) and the upper ball wheel (32) on the left and right sides clamp the optical cable accordingly; S6.
