Control circuit of direct current motor in unmanned aerial vehicle charging box

Abstract

The invention provides a control circuit of a direct current motor in an unmanned aerial vehicle charging box. The control circuit comprises a direct current motor driving chip; the direct-current motor driving chip comprises an input control end and an output motor control end, and the output motor control end is connected with the direct-current motor and used for receiving input signals of the single-chip microcomputer and controlling the direct-current motor to rotate forwards or backwards according to the input signals of the single-chip microcomputer; the direct current motor driving chip comprises a current limiting control end, and the current limiting control end is connected with the current limiting control circuit and used for adjusting the current limiting value of the direct current motor. In the actual application process, the current needed for starting the direct current motor is large, but the working current in the movement process is small, and the thrust of the motor is controlled by adjusting the current limiting value of the direct current motor. A low-cost direct current motor driving chip is adopted, an existing single chip microcomputer in a system is externally utilized, simple forward and reverse rotation control is carried out through two I / O ports, special motor control resources are not needed, the structure is simple, the area is small, and cost is low.

Description

technical field [0001] The present application relates to the technical field of motor control of the UAV charging box, in particular to a control circuit for a DC motor in the UAV charging box. Background technique [0002] The UAV charging cabin is a ground device that cooperates with the autonomous and unmanned work of the UAV. It can perform functions such as charging and external remote communication for the UAV. Among them, the steps to realize the charging function of the UAV charging cabin are as follows: After the UAV performs the flight mission, the UAV charging cabin controls the motor to push the apron out, and after the UAV lands on the apron, the UAV charging cabin controls The motor drags the UAV into the UAV charging cabin for charging; after charging, push the UAV landing pad out of the UAV charging cabin to take off for the next mission. Motors and motor control circuits are used for pulling, rolling out of the apron, etc. [0003] In the prior art, a com...
