Problems solved by technology
The traditional robot battery is charged by an external wire. When the robot is low in power, it needs human assistance to charge or automatically complete the charging connection action without human participation. Chinese patent 201410856365.4 discloses a robot charging method, device and system , the method sends a pulse signal according to the detected remaining power of the robot; according to the received pulse signal, a charging instruction is issued; according to the obtained charging instruction, the robot can find a charging station for charging in time, and can charge the battery that needs to be charged. The robot is managed in an orderly manner; when the positioning signal is sent as a pulse signal, the robot can be positioned through the pulse signal; Chinese patent 201410718161.4 discloses a robot charging method, the robot sends a charging request to the charging device through wireless communication, After the charging device is allowed to charge, obtain the location of the charging device; the robot determines the route to travel according to its own position and the position of the charging device, and moves to the position of the charging device to dock with the charging device for the charging device to connect the robot charging; these methods of automatically completing charging without human participation have stricter requirements on the robot’s cruise positioning and plugging and unplugging of the socket, the charging connection is difficult, and there may be frequent misoperation; in addition, the charging plug has been plugged in many times. After unplugging, it is easy to cause poor contact due to mechanical wear and tear, resulting in unreliability of power transmission. In addition, in the existing wireless charging method for robots, in order to ensure a certain transmission power, half-bridge, full-bridge and other multi-switch tubes are often used. circuit, which not only increases the cost but also increases the volume of the charging system, and the control is complicated

Embodiment
[0024] In this embodiment, charging is implemented in the robot wireless charging device, and the specific process includes the following steps:
[0025] (1), switch on the power supply, initialize the single-chip microcomputer on the first single-chip microcomputer control circuit 9 and the second single-chip microcomputer control circuit 17, when the robot electric quantity is insufficient or when receiving the signal that remote controller 20 sends, judge whether to finish current work, if The current work is not completed, then continue to complete the current work; if the current work is completed, the second single-chip microcomputer control circuit 17 sends a charging tracking signal, and the robot begins to move to the transmitter power supply with the assistance of the external positioning system;
[0026] (2), the first wireless communication circuit 11 detects the information that the second wireless communication circuit 19 sends, if the first wireless communication...

The invention belongs to the technical field of electrics and relates to a robot wireless charging method. The method is characterized by sending a charging track-searching signal to a low-battery robot to enable the robot to move to a transmitting end power supply, and meanwhile, awakening the transmitting end power supply to go into a working state; during charging, carrying out trickle pre-charging first, then, carrying out constant-current positive and negative pulse charging, and finally, carrying out constant-voltage charging; and when a charging current drops to a preset value, locking a driving signal, reminding that the charge is finished, and realizing wireless and automatic charging of the robot. The whole circuit of a used charging device is novel and simple in structure, high in charging efficiency and easy to control; and under the same power, the circuit is low in cost and small in size; no-voltage soft-switching technology is realized; switching loss is reduced; and system reliability is improved.
Description
[0001] Technical field: [0002] The invention belongs to the technical field of electricity, and relates to a wireless charging method for a robot, in particular to a method for realizing wireless charging of a robot by using a single switching tube to invert. [0003] Background technique: [0004] The birth of robots has promoted the rapid development of human beings in industry, military and other aspects. It not only plays a pivotal role in dangerous industries such as marine, oil exploration and power maintenance, but also has gradually entered people's lives. The traditional robot battery is charged by an external wire. When the robot is low in power, it needs human assistance to charge or automatically complete the charging connection action without human participation. Chinese patent 201410856365.4 discloses a robot charging method, device and system , the method sends a pulse signal according to the detected remaining power of the robot; according to the received puls...
