Situation Analysis

of power transmission, distribution, collection lines and towers, when conducting drone inspections, the self-built communication link between the remote controller and the drone was disconnected due to tree obstruction, climbing over mountains, etc. As a result, the effective remote control distance of the drone is greatly shortened, and the drone is in a disconnected state , which has a great risk of bombing and losing. At the same time, because the segment lines are usually located in the wild, the public network signal is poor or there is no network, and 4G cannot be used for mapping. Therefore, it is seriously restricted to carry out inspections of power transmission, distribution lines and towers through drones. There is an urgent need to use relevant information and communication technologies to solve the problems encountered in carrying out drone inspections .

The current status of power inspection is as shown below:

solution

In order to solve the problem of insufficient control and image transmission distance caused by signal obstruction , the "UAV + signal relay" method is adopted, which can effectively enhance the communication transmission distance. The effective communication distance of operating UAV and relay UAV can reach More than 15 kilometers.

Drone relay mode, product features are as follows:

The entire system consists of three parts: operating drone, relay drone and ground terminal:

Operation drone terminal:

Operation drone: Considering the power supply and battery life of the aircraft, use DJI M300 or M350.

Airborne converged terminal: uses WD5000, supports PSDK/OSDK interface, supports GE port, and the whole machine weighs about 140 grams.

Relay equipment: power consumption is no more than 30W, external power supply (15~36V), weight is about 400 grams (including antenna), maximum transmission distance is more than 15 kilometers.

Relay drone terminal:

Relay UAV: Considering the power supply and battery life of the aircraft, DJI M300 or M350 is used.

Relay equipment:, power consumption is not more than 30W, external power supply (15~36V), weight is about 400 grams (including antenna), maximum transmission distance is more than 15 kilometers.

user terminal:

Middleware: Communicates with the airborne fusion terminal to achieve unified scheduling and image transmission, and provides a calling interface for the remote control or business platform. The middleware software is deployed on the airborne fusion terminal to run .

Business platform: Customer-customized business platform.

Remote control: A customized APP is required to call the middleware interface to realize drone control and image transmission.
