Object differential action detection method and device

Abstract

An object differential action detection method and a device are used for detecting a differential action value of two objects and emitting a signal to perform a default action. The method comprises the following steps: a first object is provided; the first object is provided with a metal assembly; a second object is provided, and the second object is provided with a sensing sheet of a capacitive sensor corresponding to the metal assembly on the first object; the capacitive sensor is enabled to sense different capacitances when the first object perform differential actions relative to the second object; when the position of the first object relative to the second object is obtained by means of the different capacitances, one signal is emitted to enable the default action.

Description

technical field [0001] The present invention relates to a detection method and device, especially used in a self-propelled cleaning device with autonomous displacement for cleaning work, to detect the difference between two objects for corresponding response or control Object differential detection method and device. Background technique [0002] Due to the busy work of modern people, house cleaning is more laborious and time-consuming. In order to solve this problem, so-called self-propelled cleaning devices have appeared on the market. Sweep and remove dust back and forth on the cleaning surface to achieve convenience without manual operation. [0003] If a child picks up the self-propelled cleaning device or drives the self-propelled cleaning device on an obstacle by mistake, etc., the body of the self-propelled cleaning device is suspended in whole or in part on the surface to be cleaned. The cleaning work cannot be continued, but the self-propelled cleaning device wil...

Problems solved by technology

[0003] If a child picks up the self-propelled cleaning device or drives the self-propelled cleaning device on an obstacle by mistake, etc., the body of the self-propelled cleaning device is suspended in whole or in part on the surface to be cleaned. The cleaning work cannot be continued, but the self-propelled cleaning device will continue to operate at this time. The idling drive wheels, main brushes, side sweeping brushes... and other mechanisms not only cause energy consumption, but also cause finger entanglement if children touch it. , the consequences are even more unimaginable; in order to prevent the above situation from happening, a contact sensor is set on the body of the self-propelled cleaning device to detect the contact state between the non-driving guide wheel and the contact sensor, and when the self-propelled cleaning device is to be cleaned When the cleaning work is performed normally on the surface, the contact sensor keeps in contact with the guide wheel. When the guide wheel of the self-propelled cleaning device is suspended from the ground on the surface to be cleaned, the guide wheel will fall down due to gravity and separate from the contact sensor. The contact sensor detects that the guide wheel is suspended above the surface to be cleaned, and outputs a warning signal through the control unit to remind the user
