High-reliability tethered drone airborne power supply control system

Abstract

The invention relates to a high-reliability tethered drone airborne power supply control system which comprises two circuit sources which are connected with a switching circuit module. The switching circuit carries out comparing to output one circuit with relatively higher output voltage to an output interface. The output interface comprises a low-voltage output interface and a low-voltage standbyoutput interface. The switching circuit module is connected with a current and voltage detection module which is connected with a single-chip computer. The single-chip computer switches and selects the low-voltage output interface or the low-voltage standby output interface according to the data feedback from the current and voltage detection module. The single-chip computer is connected with anauxiliary power supply. A sensor is arranged on a drone. The single-chip computer is connected with the sensor and a wireless transceiver module. The wireless transceiver module is connected with a ground control terminal. The data monitored by the sensor and the current and voltage detection module are transmitted to the ground control terminal through the single-chip computer. The system provided by the invention can collect the working state data of multiple airborne power supplies and transmit the data to the ground to enable an operator to make advance decisions to prevent accidents.

Description

technical field [0001] The invention relates to a high-reliability tethered UAV airborne power supply control system. Background technique [0002] In recent years, unmanned aerial vehicles (UAVs) have been used more and more widely in the civilian field, especially in the fields of map surveying, geological surveying, disaster monitoring, weather detection, air traffic control, border patrol monitoring, communication relay, emergency communication, etc. However, multi-rotor UAVs generally rely on onboard batteries to provide power, and cannot stay in the air for a long time under the existing technology, so the tethered UAV solution came into being. [0003] The tethered UAV is generally composed of a diesel generator on the ground, a booster power supply, a pay-off machine, an on-board power step-down module in the air, and the UAV. The cable provides power for the UAV, so that Can stay in the air for a long time to perform tasks. As the key equipment for tethered UAV ai...

Problems solved by technology

If the low-voltage output interface or the switching circuit fails, such as poor contact with the interface and the heat will cause the solder to melt, it will directly cause the plane to crash or even injure the ground operator, which may cause heavy loss of personnel and property; if the lithium battery is too low during work, it is not enough Ensuring the normal landing of drones will also pose potential risks; and the working status of the power supply during flight cannot be grasped by ground personnel, making it difficult to prevent accidents
