Problems solved by technology

[0004] However, when the automatic lawn mower 100 is originally located at certain positions closer to the docking station 200, such as figure 1 In the position where the automatic lawn mower 100 is located, the automatic lawn mower 100 searches for the closest boundary line 10 when returning, and returns to the docking station 200 counterclockwise. The return route is unreasonable and wastes electric energy

other Embodiment approach

[0067] In other embodiments, the receiving device may only have the first receiver 110, the first receiver 110 is fixed or rotatably connected to the automatic lawn mower 100, and the first receiver 110 has at least two different orientations, thus having At least two acceptance angle ranges.

[0068] If the first receiver 110 is rotatably connected to the automatic lawn mower 100, the controller controls the first receiver 110 to rotate or swing within a certain arc range when the automatic lawn mower 100 returns, so that the first receiver 110 can rotate in different positions. The ultrasonic signal is received in the azimuth, and the controller controls the walking direction of the automatic lawn mower 100 according to the signals received by the receiver in different azimuths.

[0069] If the first receiver 110 is fixedly connected to the automatic lawn mower 100, the controller controls the automatic lawn mower 100 to rotate once or swing within a certain arc range when t...

Abstract

The invention discloses a method for controlling automatic walking equipment to return to a docking station. The docking station is provided with a generating device for sending out ultrasonic signals, and the automatic walking equipment includes a controller and a receiving device. The receiving device detects ultrasonic signals, and the controller controls the walking direction of the automatic walking equipment according to the signal reception conditions of at least two receiving angle ranges of the receiving device, so that the automatic walking equipment returns to the docking station. The invention also provides an automatic return system.

Description

technical field [0001] The invention relates to an automatic return system and a method for controlling automatic walking equipment to return to a docking station. Background technique [0002] With the continuous advancement of computer technology and artificial intelligence technology, automatic working systems similar to intelligent robots have begun to slowly enter people's lives. Companies such as Samsung and Electrolux have developed fully automatic vacuum cleaners and have put them into the market. This kind of fully automatic vacuum cleaner is usually small in size and integrates environmental sensors, self-driving system, vacuum system, battery and charging system. It can cruise indoors by itself without manual control, and automatically return to the docking station when the energy is low, docking and charging. Then go on cruise vacuuming. At the same time, companies such as Haskovana have developed similar automatic lawn mowers, which can automatically mow and r...
