Autonomous mower

Abstract

An autonomous mower including 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.

         3 . An autonomous traveling device as claimed in  claim 2 , wherein the reference image is an image collected in a particular scenario when the lens is clean. 
     
     
         4 . An autonomous traveling device as claimed in  claim 2 , wherein a shooting position of the real-time image is identical to the preset position which ensures that the scenario of the real-time image is identical to that of the reference image. 
     
     
         5 . An autonomous traveling device as claimed in  claim 2 , wherein the real-time image is collected each time before the autonomous traveling device starts from a charging station or a starting station. 
     
     
         6 . An autonomous traveling device as claimed in  claim 2 , wherein the reference image is an image collected in the position of the charging station or the starting station when the lens is clean. 
     
     
         7 . An autonomous traveling device as claimed in  claim 1  wherein the alarm module is a sound system, a luminous system or a mobile device transmitted to the user through communication. 
     
     
         8 . The autonomous traveling device according to  claim 1 , farthing including a cleaning device for keeping said lens clean, said cleaning device including a shielding sheet disposed on said lens which can be moved to shield or expose said lens, and said shielding sheet is provided thereon with a cleaning element that cleans said lens when said shielding sheet is moved. 
     
     
         9 . The autonomous traveling device according to  claim 8 , said cleaning element is a cleaning brush or flaky cleaning plate. 
     
     
         10 . The autonomous traveling device according to  claim 8 , said cleaning element is detachably installed on said shielding sheet. 
     
     
         11 . The autonomous traveling device according to  claim 1 , further including a cleaning device for keeping said lens clean, said cleaning device including a microfan disposed on said lens which produces air currents to clean said lens. 
     
     
         12 . The autonomous traveling device according to  claim 11 , said microfan including fan blades made of piezoelectric material, and high-frequency vibration of said fan blades produces said air currents. 
     
     
         13 . The autonomous traveling device according to  claim 1 , further including a cleaning device for keeping said lens clean, said cleaning device including a transparent cover that surrounds said image acquisition device therein and a cleaning element that cleans said transparent cover. 
     
     
         14 . The autonomous traveling device according to  claim 13 , said cleaning element including a cleaning brush fixed to one side of said image acquisition device opposite to said lens, said transparent cover is rotatable around said image acquisition device, and when said transparent cover rotates around said image acquisition device, said cleaning brush can clean said transparent cover. 
     
     
         15 . The autonomous traveling device according to  claim 14 , said cleaning brush is detachably installed on one side of said image acquisition device opposite to said lens. 
     
     
         16 . The autonomous traveling device according to  claim 15 , said transparent cover is driven through a motor, and automatically rotates around said image acquisition device. 
     
     
         17 . The autonomous traveling device according to  claim 13 , said cleaning element including a cleaning brush for cleaning said transparent cover, and said cleaning brush is located on an outer side of said transparent cover facing said lens.
