Description

An optical cable online inspection system and method based on catamaran airship UAV technology

Technical Field

The present invention belongs to the technical field of optical cable inspection, and in particular to an optical cable online inspection system and method based on catamaran airship UAV technology.

Background technique

Communication Optical Fiber Cable is composed of a cable core and an outer sheath consisting of several optical fibers (usually from a few to several thousand). Compared with traditional symmetrical copper loops and coaxial copper loops, optical fiber has much larger transmission capacity, less attenuation, longer transmission distance, smaller size, lighter weight, no electromagnetic interference, and lower cost. It is currently the most promising communication transmission medium. It is widely used in signal transmission in telecommunications, power, broadcasting and other departments, and will gradually become the main body of future communication networks.

At present, the inspection and fault detection of power communication optical cables have the following shortcomings:

⑴. At present, the inspection and fault detection of power communication optical cables are still based on the traditional manual inspection method, which has fewer monitoring dimensions and cannot quickly locate the fault point of the optical cable terminal, and the efficiency needs to be improved;

⑵. When using drones, due to the problem of drone patrol battery capacity, the drone's endurance is not strong, and the long-term stay limit has shortcomings for long-distance optical cable patrols. What low-cost and highly flexible method can be used to carry out drone relay patrols?

⑶. It is impossible to inspect multiple lines simultaneously or handle simultaneous faults, which cannot meet the requirements of high-quality operation and maintenance level of communication optical cable lines.

(4) Due to the limitation of transmission distance, what kind of communication method does the drone rely on to transmit real-time data to the terminal?

Summary of the invention

The purpose of the present invention is to overcome the shortcomings of the prior art and propose an optical cable online inspection system and method based on catamaran airship UAV technology, which realizes multi-dimensional online monitoring of optical cable line equipment and transmits the monitoring data to the monitoring station and terminal, making it convenient for communication operation and maintenance personnel to understand the equipment status and find fault points in time, saving labor costs and greatly improving the operation and maintenance level of optical cable lines.

The present invention solves the technical problem by adopting the following technical solutions:

The UAV daughter machine is placed inside the catamaran UAV airship mother ship. The monitoring station and the terminal send 5G communications with the catamaran UAV airship mother ship and the UAV daughter machine through the 5G base station. The catamaran UAV airship mother ship and the UAV daughter machine perform corresponding actions according to the communication content.

Moreover, the catamaran UAV airship mothership includes: solar film panels, voltage stabilizing devices, controllers, 5G signal receivers, charging and discharging power supplies and UAV daughter machine charging devices. A solar film panel is arranged on the top of the catamaran UAV airship mothership, and a voltage stabilizing device, controllers, 5G signal receivers, charging and discharging power supplies and UAV daughter machine charging devices are arranged inside the catamaran UAV airship mothership.

Step 1: The monitoring station and the terminal determine whether the operation and maintenance personnel input daily inspection or fault inspection. If the operation and maintenance personnel input daily inspection, step 2 is performed; if it is an accident inspection, step 3 is performed;

Step 2: The monitoring personnel at the monitoring station and the terminal find the interruption warning of the optical cable. The monitoring station and the terminal set the starting point, length and end point of the inspection optical cable along the actual path of the optical cable, and proceed to step 5;

Step 3: The monitoring station and the terminal detect the location and length information of the faulty optical cable;

Step 4: The monitoring station and the terminal set the starting point, length and end point of the inspection optical cable according to the location and length information of the faulty optical cable obtained by monitoring, along the actual path of the optical cable;

Step 6: The 5G signal receiver inside the catamaran drone airship mothership receives the signal and transmits it to the controller, and the controller controls the catamaran drone airship mothership to fly to the set starting point;

Step 7: After the catamaran UAV airship mothership arrives at the starting point, the UAV sub-machine is released, and the UAV sub-machine inspects the optical cable from the starting point to the end point and collects the optical cable GIS information;

Step 8: After the drone sub-machine reaches the end point, it flies back to the inside of the catamaran drone airship mother ship, and the catamaran drone airship mother ship leaves the fault position.

Moreover, the drone sub-machine is provided with a camera, and when the drone sub-machine collects the optical cable GIS information in step 7, the collected video or picture is transmitted to the monitoring station and the terminal in real time.

Moreover, the drone sub-machine transmits videos or pictures through a 5G transmission channel or satellite communication.

Moreover, if the routine inspection in step 1 includes multiple optical cables, the drone sub-machines are set to form a swarm mode to collect optical cable GIS information.

Moreover, in step 3, if the monitoring station and the terminal detect that the length of the faulty optical cable is too long and exceeds the flight distance of the drone, a relay inspection is performed by arranging a catamaran drone airship mother ship as a relay point.

Moreover, the relay method comprises the following steps:

Step ⑴: According to the location and length information of the faulty optical cable detected by the monitoring station and the terminal, set the starting point, length and end point of the inspection optical cable along the actual path of the optical cable and generate the inspection path.

Step 2: According to the inspection route, at the starting point, the end point and the route, a catamaran drone airship mothership is deployed at a certain distance according to the actual flight distance limit of the current drone sub-machine as the radius;

Step (3): the drone sub-machine flies out from the starting point catamaran drone airship mother ship for inspection, and enters the nearest catamaran drone airship mother ship according to the route for charging;

Step (4) The catamaran drone airship mothership determines whether there is an inspection drone sub-machine for charging. If a drone sub-machine flies in and is charging, another drone sub-machine is dispatched to continue the inspection along the inspection route, otherwise it continues to wait;

Step (5), the dispatched drone sub-machine determines whether the incoming catamaran drone airship mothership is the ending point catamaran drone airship mothership. If the incoming catamaran drone airship mothership is the ending point catamaran drone airship mothership, no drone sub-machine will be dispatched, otherwise return to step (4).

The advantages and positive effects of the present invention are:

At the same time, when multiple optical cables are inspected at the same time, multiple communication optical cables fail at the same time, or multiple locations fail at the same time, drone sub-machines can form a swarm mode, and collective action can give full play to efficiency advantages.
