An unmanned aerial vehicle automatic charging platform and automatic charging method

Abstract

The invention discloses an unmanned aerial vehicle automatic charging platform and automatic charging method, which has low landing accuracy requirement for the UAV, relatively simple structure and low failure rate. The unmanned aerial vehicle automatic charging platform comprises a shutdown platform, a plurality of constraint members disposed on the shutdown platform, a drive unit for driving each of the restraining members and a charging unit provided on at least one of the restraining members, each restraint member surrounds to form a landing area, and the drive unit moves to zoom the landing area by driving the restraint member. When the UAV parked in the landing area moves to the middle of the landing area under the restraint of each restraint member, the charging port on the UAV is in electrical contact with the charging unit on the restraint member.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an automatic charging platform and an automatic charging method for unmanned aerial vehicles. Background technique [0002] With the rapid development of the drone industry, drones are increasingly widely used in people's production and life. At present, rotor drones mainly use electricity as power. At present, drones are usually charged by manual operation, but manual operation increases labor costs, which is not conducive to automation. In the prior art, there are some schemes that can realize the automatic charging of drones, and the automatic charging methods of drones generally have the following types: [0003] (1) The battery is automatically loaded and unloaded by a manipulator. This method has many mechanical structures, complex design mechanisms, relatively high cost, and requires high positioning accuracy to complete automatic battery replacement. Due...

Problems solved by technology

[0003] (1) The battery is automatically loaded and unloaded by a manipulator. This method has many mechanical structures, complex design mechanisms, relatively high cost, and requires high positioning accuracy to complete automatic battery replacement. Due to the relatively complicated mechanical structure and circuit structure, this method does not work. The failure rate is high and the maintenance cycle is short; in addition, this method is limited by the safe stroke of the manipulator, and requires a large installation space

[0004] (2) The charging interface is automatically plugged in for direct connection charging. In this way, the power cord of the drone is led out to one end, and the charging ports at both ends are directly connected and charged through positioning calibration. This charging method also requires higher positioning. Accuracy, matching charging can be performed only when the UAV normally lands in the designated area, or mobile calibration through the ground charging terminal, but this also increases the complexity of the structure, and the corresponding cost, failure rate, installation space and other issues are also In addition, most of the direct-connected charging will place the power supply at the same position. Due to the deviation of positioning accuracy, wrong charging of the power supply, wrong connection of positive and negative poles, etc. will cause a large current impact on the entire charging system, and even cause the entire charging system to fail. System crash and damage, high insecurity

[0006] In the above-mentioned patents, the positioning of the UAV is realized by identifying the positioning mark on the charging platform, which requires extremely high precision for the landing of the UAV. When the error of the UAV landing is large, the charging contact on the landing gear and the If the contacts on the charging platform are misplaced, the charging function cannot be realized
