Abstract

An autonomous mower includes a housing; a mowing module, a traveling module, an information collection device, an energy module, a control module and the control module includes an identification unit, and an alarm module. The autonomous mower has a security patrol working mode in which the identification unit analyzes and judges whether an abnormal object exists in the working area according to the information collected by the information collection device; if the abnormal object exists, the control module controls the alarm module to send an alarm signal to the outside. Therefore, the autonomous mower can achieve a security patrol function in addition to having a function of trimming the lawn. The autonomous mower has multiple uses, so as to save the cost.

First claim

1 . An autonomous mower which automatically travels and works in a working area, the autonomous mower comprising:
a housing; a mowing module received in the housing, and performing predetermined mowing work; a traveling module supporting the housing and driving the autonomous mower to travel in a working area; an information acquisition device disposed on the housing and used for acquiring external environment information; an energy module providing energy for the autonomous mower; and a control module connecting and controlling the mowing module, the traveling module, the information acquisition device and the energy module, to achieve automatic traveling and automatic working of the autonomous mower; and an alarm module for making an alarm, wherein the control module comprises an identification unit which receives the external environment information; the identification unit analyses and judges whether an abnormal object exists in the working area according to the external environment information; if an abnormal object exists, the control module controls the alarm module to send an alarm signal to the outside; and the information acquisition device has multiple perspectives, the information acquisition device acquires the external environment information from different perspective according to the alarm signal or the external environment information.

2 . The autonomous mower according to claim 1 , wherein the information acquisition device acquiring the external environment information from different perspective according to the alarm signal or the external environment information comprises:
the autonomous mower rotating according to the alarm signal or the external environment information.

3 . The autonomous mower according to claim 1 , wherein the information acquisition device acquiring the external environment information from different perspective according to the alarm signal or information acquired by the external environment information comprises:
the information acquisition device rotating according to the alarm signal or the external environment information.

4 . The autonomous mower according to claim 1 , wherein the information acquisition device acquiring the external environment information from different perspective according to the alarm signal or the external environment information comprises:
the control module controlling the traveling module to move according to the alarm signal or the external environment information.

5 . The autonomous mower according to claim 1 , wherein the information acquisition device acquiring the external environment information from different perspective according to the alarm signal or information acquired by the external environment information comprises:
the information acquisition device switching to different acquisition device types according to the alarm signal or the external environment information.

6 . The autonomous mower according to claim 3 , wherein the information acquisition device comprises an image acquisition device.

7 . The autonomous mower according to claim 6 , wherein the image acquisition device is rotatably fixed onto the housing.

8 . The autonomous mower according to claim 7 , wherein the autonomous mower further comprises a driving device that drives the image acquisition device to make rotational motion, and the control module controls the rotational motion of the image acquisition device through the driving device.

9 . The autonomous mower according to claim 8 , wherein the image acquisition device is controlled to rotate by a control instruction from the outside.

10 . The autonomous mower according to claim 8 , further comprising a wireless communication module comprising a Wi-Fi module, a cellular communication module or a Bluetooth module.

11 . The autonomous mower according to claim 10 , wherein the alarm signal comprises images, texts or audio alarm signals, the alarm module transmits images, texts or audio alarm signals to the outside through the wireless communication module.

12 . The autonomous mower according to claim 9 , wherein the autonomous mower receives the control instruction sent from the outside through the wireless communication module, and controls the image acquisition device to acquire the external environment information from different perspective according to the control instruction.

13 . The autonomous mower according to claim 4 , wherein the control module controls the traveling module to move according to another control instruction from the outside, the another control command is sent according to the alarm signal or the external environment information.

14 . The autonomous mower according to claim 13 , further comprising a wireless communication module comprising a Wi-Fi module, a cellular communication module or a Bluetooth module.

15 . The autonomous mower according to claim 14 , wherein the wireless communication module transmits the external environment information to the outside.

16 . The autonomous mower according to claim 15 , wherein the autonomous mower receives the another control instruction sent from the outside through the wireless communication module, and controls the traveling module to move according to the another control instruction.

17 . The autonomous mower according to claim 1 , wherein the identification unit of the control module analyses and judges whether an abnormal object exists in the working area according to the external environment information;
if an abnormal object exists, the information acquisition device acquires the external environment information from a different perspective; the identification unit of the control module analyses and judges whether an abnormal object exists in the working area according to the external environment information again; if an abnormal object still exists, the control module controls the alarm module to send an alarm signal to the outside.
