Abstract

The invention relates to a ground recognition method and a device and a sweeping robot. The method comprises the following steps: enabling a to-be-detected ground to emit an ultrasonic signal throughan ultrasonic sensor, determining the wave width of an ultrasonic echo signal of the to-be-detected ground, and determining the ground material of the to-be-detected ground according to a wave width range corresponding to the wave width. Based on this, the ground type is accurately recognized, so that the sweeping robot can select a correct sweeping mode according to the recognized ground type, and damage to the ground is prevented.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a ground recognition method and device, and a sweeping robot. Background technique [0002] Sweeping robot, also known as automatic cleaning machine, intelligent vacuum cleaner, robot vacuum cleaner, etc., is a kind of smart household appliances, which can automatically complete the ground cleaning work in the cleaning space by virtue of certain artificial intelligence. Among them, the sweeping robot is equipped with a walking mechanism to automatically walk in the cleaning space. At present, with the wide application of sweeping robots, the types of floors that sweeping robots are used to clean spaces are also becoming more and more abundant. Different ground types correspond to different cleaning requirements, and different ground types will also affect the walking status of the sweeping robot. [0003] However, it is difficult for traditional sweeping robots to accurately id...
