Abstract

Embodiments of the present invention relates to a self-moving apparatus and a method for controlling same, the self-moving apparatus including: a housing; a movement module for driving the housing to move; an ultrasonic module configured to transmit an ultrasonic signal and receive an echo signal formed through reflection of an obstacle; and a control module installed on the housing and connected to the ultrasonic module, to implement an ultrasonic detection function by processing the echo signal, thereby controlling a movement mode of the movement module. The control module can control disabling of the ultrasonic detection function according to a received preset signal.

Claims (24)

1. A self-moving apparatus, comprising:

a housing;

a driving wheel and a driven wheel installed on the housing for driving the housing to move;

an ultrasonic probe configured to transmit an ultrasonic signal and receive an echo signal formed through reflection of the ultrasonic signal by an obstacle;

a main control board, installed on the housing and connected to the ultrasonic probe, configured to implement an ultrasonic detection function by processing the echo signal transmitted to the main control board from the ultrasonic probe, thereby controlling a movement mode of the driving wheel and the driven wheel; and

an energy module, connected to the main control board, configured to monitor a current electric quantity of the self-moving apparatus, and to send a low-energy signal to the main control board when the current electric quantity is insufficient,

wherein the main control board is configured to disable the ultrasonic detection function according to the low-energy signal sent by the energy module, the low-energy signal being an energy signal whose energy is less than a preset energy, and to control the self-moving apparatus to return to a charging station based on a generated return path according to a current position of the self-moving apparatus or a predetermined return path.

2. The self-moving apparatus according to claim 1 , wherein the main control board is further configured to disable the ultrasonic detection function according to a manual control signal.

3. The self-moving apparatus according to claim 2 , wherein the manual control signal is generated by a user operation.

4. The self-moving apparatus according to claim 2 , wherein the self-moving apparatus is configured to communicate with the main control board, and receive the manual control signal sent by a terminal.

5. The self-moving apparatus according to claim 2 , wherein the self-moving apparatus comprises a display apparatus connected to the main control board, the manual control signal being generated by the display apparatus.

6. The self-moving apparatus according to claim 1 , wherein the main control board is further configured to disable the ultrasonic detection function according to an abnormal signal.

7. The self-moving apparatus according to claim 6 , wherein the abnormal signal comprises a valid signal that satisfies a preset condition.

8. The self-moving apparatus according to claim 7 , wherein the preset condition comprises a time being greater than a preset time or a number being greater than a preset number.

9. The self-moving apparatus according to claim 7 , wherein the valid signal comprises an echo signal with strength greater than a preset strength.

10. The self-moving apparatus according to claim 1 , wherein the disabling of the ultrasonic detection function comprises stopping operation of the ultrasonic probe.

11. The self-moving apparatus according to claim 1 , wherein the disabling of the ultrasonic detection function comprises stopping processing the echo signal by the main control board.

12. The self-moving apparatus according to claim 1 , wherein a detection range of the ultrasonic probe in a height direction is a first height range, and the self-moving apparatus further comprises an auxiliary detecting probe configured to detect an obstacle within a second height range.

13. The self-moving apparatus according to claim 12 , wherein the main control board controls the movement mode according to an output signal of the ultrasonic probe or the auxiliary detecting probe.

14. A method for controlling a self-moving apparatus, the self-moving apparatus comprising a driving wheel and a driven wheel, an ultrasonic probe, a main control board, and an energy module, the ultrasonic probe transmitting an ultrasonic signal and receiving an echo signal formed through reflection of an obstacle, the main control board being connected to the ultrasonic probe to implement an ultrasonic detection function, thereby controlling a movement mode of the driving wheel and the driven wheel, and the energy module connected to the main board to monitor a current electric quantity of the self-moving apparatus, and to send a low-energy signal to the main control board when the current electric quantity is insufficient;

wherein the control method comprises:

receiving, by the main control board, a the low-energy signal sent by the energy module, the low-energy signal being an energy signal whose energy is less than a preset energy;

controlling, by the main control board, disabling of the ultrasonic detection function based on at least the low-energy signal; and

controlling the self-moving apparatus to return to a charging station based on a generated return path according to a current position of the self-moving apparatus or a predetermined return path.
