Sweeping machine and method for preventing it from falling

Abstract

The invention discloses a floor sweeping robot which comprises a body and a control unit. A drop-preventing detection unit is arranged on the edge of the bottom of the body and detects different states of the robot, including normal, off-ground, suspended and dropping states. A walking unit and a cleaning unit are arranged at the bottom of the body. A control unit is connected with the drop-preventing detection unit, the walking unit and the cleaning unit and is used for controlling the walking unit and the cleaning unit to execute corresponding working modes according to the different state of the robot. It can be seen that the floor sweeping robot detects the different states of the robot through the arranged drop-preventing detection unit, and the robot executes the corresponding different working modes according to different states, so that the robot has the function of making the most appropriate response according to different dropping situations, low working efficiency caused by frequent retreating is avoided, and accordingly the working efficiency of the floor sweeping robot is improved.

Description

technical field [0001] The invention relates to the field of sweeping robots, in particular to a sweeping robot and a method for preventing it from falling. Background technique [0002] With the development of society and the advancement of science and technology, smart sweepers have entered ordinary households. In order to prevent them from falling from a high place and causing damage to the machine, the existing smart sweepers generally use infrared sensing to measure distances. An infrared induction ranging sensor, after emitting an infrared signal through the sensor, receives the infrared signal, and judges whether the machine is in a falling state according to the change of the received infrared signal. At this time, if you encounter a suspected fall situation, such as a small ditch, a small hole, or a very short step, it will be judged as a fall, and the machine will perform anti-fall protection and generally retreat. [0003] This way of identifying falls has result...

[0002] With the development of society and the advancement of science and technology, smart sweepers have entered ordinary households. In order to prevent them from falling from a high place and causing damage to the machine, the existing smart sweepers generally use infrared sensing to measure distances. An infrared induction ranging sensor, after emitting an infrared signal through the sensor, receives the infrared signal, and judges whether the machine is in a falling state according to the change of the received infrared signal. At this time, if you encounter a suspected fall situation, such as a small ditch, a small hole, or a very short step, it will be judged as a fall, and the machine will perform anti-fall protection, generally backward

[0003] This way of identifying falls has resulted in the implementation of anti-drop protection in some conditions that should have been able to operate normally, causing the machine to retreat or turn frequently, which greatly reduces the working efficiency of the sweeping robot.
