Charging stand, calibration method and device for charging stand position, and sweeping system

Abstract

The invention relates to the technical field of cleaning control, in particular to a charging stand, a method for calibrating the position of the charging stand, a device and a sweeping system. Among them, there are a plurality of magnetic devices arranged regularly on the charging base, and the calibration method includes: when the sweeper detects a detection point with a magnetic field during its movement, record the coordinate information and magnetic field strength information of the detection point and adjust the forward direction Continue detection; generate a fitting curve based on the coordinate information corresponding to each detection point; determine the target magnetic field strength based on the magnetic field strength information of all detection points on the fitting curve; judge whether the fitting curve conforms to the preset curve and whether the target magnetic field strength meets the preset Set the magnetic field strength; when the fitting curve conforms to the preset curve and the target magnetic field strength meets the preset magnetic field strength, it is determined that the coordinate information corresponding to the detection point on the fitting curve is the position of the charging stand. By implementing the invention, the accuracy of the position calibration of the charging stand can be ensured, and the collision between the sweeper and the charging stand can be avoided.

Description

technical field [0001] The invention relates to the technical field of cleaning control, in particular to a charging stand, a method for calibrating the position of the charging stand, a device and a sweeping system. Background technique [0002] With the development of smart homes, smart sweepers have entered thousands of households. Usually, the right side of the sweeper is equipped with an optical sensor. During the sweeping process of the sweeper, the optical sensor can receive the specific signal emitted by the charging stand to calibrate the position of the charging stand, so as to prevent the sweeper from being in contact with the charging station during the cleaning process. seat collided. However, the optical sensor is easily affected by ambient light and since the optical sensor is placed on the side of the sweeper, the sweeper can easily bump into the charging stand during the cleaning process, causing the charging stand to shift, resulting in inaccurate calibrat...
