Description

Automatic control system for an unmanned aerial vehicle used to detect malfunctions of elements of overhead power lines.

Technical field

The identification and localization of faults in power systems is important for many reasons, including the prevention of accidents in power systems, such as power outages, damage to power system equipment, electric shock to people, and other emergencies.

The utility model relates to an automatic control system for an unmanned aerial vehicle used to detect malfunctions of overhead power line elements.

Also, the utility model relates to unmanned aerial vehicles (UAVs) used to detect malfunctions of elements of overhead power lines.

State of the art

From the patent of the Russian Federation 2457531, IPC G05D 1/00, published July 27, 2012, there is a known method for using UAVs based on adapting the flight mode by using several (more than three) UAVs as data transmitters over a radio channel with a ground base station.

The disadvantage is the need to use several (more than three) UAVs. In addition, in the event of a malfunction, loss of charge of one UAV, the entire radio channel with the ground base station is lost.

From the patent of the Russian Federation 2554517, IPC H04W 92/00, which was published on 02/10/2015, the well-known complex provides radio communication with an unmanned aerial vehicle UAV through the main satellite communication channel from a stationary or mobile control center of the control center. To ensure a safe landing of UAVs, conduct video monitoring of the terrain, UAV territory surveys are additionally equipped with an IP camera, and to ensure local communication between subscribers, the UAV is equipped with a complex of on-board KBS UAV systems, which include a UAV repeater and a converter, which through a switching router KM communicates with subscribers working in different frequency ranges both within the local network and between subscribers and the control center using a satellite communication system. The disadvantage is the need to use a satellite communication system, which seems to be a technically difficult system of the described communication channel.

Technical problem

The claimed utility model solves the following technical problems.

The key technical problem when using unmanned aerial vehicles (UAVs), which are designed to identify and localize faults in power systems, is the reliable operation of the communication channel, which is crucial for the safe and efficient operation of UAVs. UAVs need a high-quality communication channel, proper integration of all UAV components and the ground station, as well as an accurate choice of communication frequencies. Also, for security reasons, the communication channel should be encrypted.

Thus, the technical problem is the high technical requirements for the data transmission channel between the UAV and the ground base station.

Another technical problem is ensuring the accurate positioning of UAVs in the dimensions of long narrow corridors of power transmission lines with ensuring the necessary availability of communication and navigation signals during the entire flight.

Another technical problem is the provision of the necessary flight range parameters for the economical operation of the system, for example, the UAV battery being able to continuously recharge, so that the UAV can use a power source at a considerable distance from the ground base station.

Another technical problem is that UAVs cannot operate without the support of elements of a remote control system. At the same time, the same UAV is not always operated with the same runway and with the same base station, using the same data channel.

Thus, the technical result of the claimed utility model is the possibility of introducing UAVs operated from several sites at several base stations using reliable data transmission channels with the necessary availability of communication and navigation signals during the entire flight and, therefore, providing the necessary parameters of the flight range .

Brief Description of the Drawings

The utility model is illustrated by the attached figure 1, which schematically shows the following elements of an unmanned aerial vehicle: 1-UAV, 2-communication module, 3- base station, 4- control center, 5- UAV charging module, 6- main communication channel, 7- additional link.

Utility Model Implementation

In a specific embodiment of the utility model, during the execution of the flight mission, the unmanned aerial vehicle (1) contains a communication module (2), made in the form of a transceiver with a main broadband communication channel (6), receives control commands, and also transfers it to the control center ( 4) telemetry data and positioning data.

The main communication channel for data transmission should provide redundancy using several signals at several frequencies. The main broadband communication channel receives telemetry data with a small delay (less than 50 ms in both directions), receives control commands, as well as positioning data of the global navigation system (GNSS).

In a specific embodiment of the utility model, when landing an UAV (1) on the landing site of the base station (3), the unmanned aerial vehicle (1) contains a communication module (2) made in the form of a transceiver with an additional high-speed narrow-band communication channel (7) made with the ability to transmit in the near zone the collected data of graphic images from the UAV (1) through base stations (3) to the control center (4).

An additional communication channel (7) should provide communication between base stations (3) and a control center (4), as well as communication between UAVs (1) and a base station (3) containing a UAV battery charging module in the near zone with a high transmission rate data up to 650 Mbps.

In a specific embodiment, the unmanned aerial vehicle (1) comprises a battery (e.g., a lithium polymer type) with a voltage, current, and battery level controller. Data from the controller through the main communication channel (6) comes through the base station (3) to the control center (4), where it is analyzed.

In the event of a decrease in the battery parameters below the specified parameters, warning and interruption commands are transmitted from the control center (4) through the main communication channel (6). After that, the UAV (1) lands on the landing site of the base station (3), located in the UAV-based place where the UAV battery is charged.

Thus, it is possible to introduce UAVs that can be operated from several sites at several base stations using reliable data transmission channels, ensuring the necessary availability of communication and navigation signals during the entire flight. This ensures the necessary parameters of the UAV flight range, for example, enabling the UAV battery to be continuously recharged, so that the UAV can use a power source at a considerable distance from the ground base station.
