Abstract

The invention relates to a cliff detection circuit and a sweeping robot. The cliff detection circuit comprises a capacitive sensor, an oscillation circuit and a state monitoring circuit. The capacitive sensor is arranged on the bottom portion of the sweeping robot and used for detecting the floor surface and outputting floor surface feedback information; the oscillation circuit is used for outputting an indication signal for feeding back floor surface state according to the floor surface feedback information, wherein the floor surface state is used for indicating whether the capacitive sensor is in a suspended state, the suspended state being a state when the distance between the floor surface and the capacitive sensor exceeds sensing distance of the capacitive sensor; and the state monitoring circuit is used for determining the floor surface state according to the indication signal, and sending a control signal for controlling the sweeping robot to carry out corresponding action. Through the capacitive detection mode, the detection effect is not affected by the ground color, so that judgment accuracy can be improved, and the sweeping robot is better in adaptability to environment.

Description

【Technical field】 [0001] The invention relates to the field of electronic technology, in particular to a cliff detection circuit and a sweeping robot thereof. 【Background technique】 [0002] At present, due to its convenience, the sweeping robot has become a household item that more and more people will choose to use. Since the surface to be cleaned is often not completely on a plane, there are usually some structures such as steps. [0003] Therefore, the sweeping robot generally needs to have a function, that is, the ability to judge whether it has walked to the edge of the ground. This ability can be called the cliff detection function to prevent the robot vacuum from falling off the edge of the surface. Most of the existing sweeping robots use laser detection to identify whether a part is in a suspended state, so as to judge whether the sweeping robot has reached the edge of the ground surface, and the control system of the sweeping robot decides whether to stop or tur...
