Floor sweeping robot with threshold detection function and threshold detection method thereof

Abstract

The invention discloses a floor sweeping robot with a threshold detection function and a threshold detection method thereof. The threshold detection system comprises a wall-following detection component, a universal wheel walking distance measuring component, a collision detection component, a MCU and a walking drive component. The wall-following detection component, the universal wheel walking distance measuring component and the collision detection component are respectively connected with the sampled signal input end of the MCU, and the control signal output end of the MCU is connected with the walking drive component. According to the floor sweeping robot with the threshold detection function and the threshold detection method thereof, by the aid of the structural feature of a threshold and the structural feature of the floor sweeping robot itself, the threshold detection system is designed, the design is reasonable, no any extra detection accessory is needed, and cost is low; the threshold can be intelligently recognized and judged by integrating the universal wheel forward-moving information, three-axis magnetoresistive sensor reading variation and front end infrared ground-penetrating sensor signals, the recognition precision is high, the reliability is good, the structure is simple, and the cost is low.

Description

Technical field [0001] The invention relates to the field of intelligent cleaning robots, in particular to a floor sweeping robot supporting threshold detection and a threshold detection method. Background technique [0002] With the continuous improvement of people's living standards, the application of smart home appliances has become more and more extensive, and has a very broad market prospect. Sweeping robots, also known as automatic cleaners, smart vacuum cleaners, robotic vacuum cleaners, etc., are a type of smart household appliances that can automatically complete floor cleaning in the room with a certain artificial intelligence. Generally, brushing and vacuuming methods are used to first absorb ground debris into its own garbage storage box, thereby completing the function of ground cleaning. Sweeping robots were first sold in the European and American markets, and with the improvement of domestic living standards, they gradually entered the Chinese market. [0003] At ...

Problems solved by technology

On the one hand, the infrared wall method is the company's patented technology, which has application limitations; on the other hand, the infrared wall method has complex algorithms and is prone to errors

[0005] 2) Close the door. Although this method can prevent the robot from running out of the door, closing the door will affect the function of the machine automatically returning to the charging stand for charging, and it cannot continuously clean multiple rooms.
