Embodiment Construction

[0035] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings, but the applicant's description of the embodiments is not a limitation to the technical solution, and any changes based on the concept of the present invention in form but not in essence should be regarded as the protection scope of the present invention.

[0036] see figure 1 , the present invention relates to a gyroscope angle correction method of a sweeping machine. Those skilled in the art know that sweeping machines have their own appearance designs, including circular sweeping machines and square sweeping machines. Those skilled in the art can understand that sweeping machines The specific appearance design of the machine does not affect the actual protection scope of the present invention. The specific gyroscope angle correction method includes the following steps:

[0037] S100) Obtain the angle θ1 of the gyroscope at the first m...

Abstract

The invention discloses a sweeper gyroscope angle correction method and a sweeper, and belongs to the technical field of sweeping equipment. The sweeper gyroscope angle correction method is characterized by comprising the following steps: S100) obtaining a gyroscope angle [theta]1 at a first moment after a gyroscope of the sweeper is reset, and establishing a two-dimensional rectangular plane coordinate system according to the angle [theta]1; S200) acquiring a gyroscope angle [theta]2 at a second moment after the sweeper walks linearly, and acquiring a direction angle [theta]3 of the two-dimensional rectangular plane coordinate system according to the angle [theta]2; and S300) correcting the gyroscope angle by using the angles theta1 and [theta]3 so as to obtain a real angle [theta]2' of the gyroscope. The invention also discloses the sweeper adopting the gyroscope angle correction method, wherein the sweeper has the advantages that the path planning effect of the sweeper is improved,and the situations of repeated sweeping, missing sweeping and the like are avoided.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to a method for correcting the angle of a gyroscope of a sweeping machine and the sweeping machine. Background technique [0002] Sweepers have a relatively high penetration rate at present, and most sweepers are equipped with gyroscope sensors to help sweepers realize route planning and regular walking and cleaning functions. The gyro sensor mainly judges the walking direction of the sweeper and provides the function of heading angle. The gyroscope is accurate in a short period of time. As the sweeper works for a long time, the gyroscope will drift and the angle will have cumulative errors, which will affect the The path of the sweeper. An external solution to the accumulated error of the gyroscope is required. [0003] At present, smart sweeper products generally use gyroscope sensors to realize path planning. The advantage of using gyroscope sensors is th...
