WORK VEHICLE AND BASE STATION
FIG9 is a diagram showing a configuration of a base station
FIG9 shows a plan view of a grounding surface 101 to which the wheels 2 of the work vehicle 1 are grounded at the base station 100, and also shows a schematic view of the base station 100. As shown in FIG9, the base station 100 includes a shower unit 31, an air blower unit 32, a return detection unit 33, a control unit 34, a second captured image acquisition unit 35, a diagnosis unit 36, and an announcement unit 37. Here, the mowing blade 26 has a circular shape when viewed from above. In view of this, as shown in FIG9, a configuration is possible in which a plurality of shower units 31 and a plurality of air blower units 32 are alternatingly arranged coaxially with the mowing blade 26 so as to together form a single circular shape. This therefore prevents cases where some portions are not washed or are not dried. Of course, a configuration is possible in which the shower unit 31 forms a circular shape on its own, and the air blower unit 32 forms a circular shape on its own inward or outward of the shower unit 31 in the diameter direction.

['1. A work vehicle configured to perform work while traveling autonomously, comprising: a drive wheel unit (2A) that is provided in a vehicle body (3) and is configured to be driven by a travel drive mechanism (10); a work unit (25) that is provided in the vehicle body (3) and is configured to perform work on a work target; a battery (5) provided in the vehicle body (3); and a motor (4) that is configured to receive electric power from the battery (5) and to drive the work unit (25), characterized by : an inclination sensor (21) configured to detect an inclination of the vehicle body (3) relative to a horizontal plane; a first captured image acquisition unit (22) configured to acquire a captured image that shows surroundings of the vehicle body (3) when the work is being performed; a first determination unit (23) configured to determine whether or not the work can be continued while traveling autonomously, based on at least one of a detection result from the inclination sensor (21) and the captured image; and a stop unit (24) configured to stop driving of the drive wheel unit in a case where the first determination unit (23) determined that the work cannot be continued.', '5. The work vehicle according to any one of claims 1 to 4,  characterized by : a battery identification information acquisition unit (202) configured to acquire preset identification information from a charging device (201A) configured to charge only the battery (5) that has the preset identification information; an identification information determination unit (203) configured to determine whether or not the preset identification information acquired by the battery identification information acquisition unit (202) matches identification information of the battery (5) provided in the vehicle body (3); and a permission unit (204) configured to permit charging of the battery (5) in a case where the identification information determination unit (203) determined that the preset identification information matches the identification information of the battery (5) provided in the vehicle body (3), wherein the charging device (201A) is configured to be provided in a base station (100) to which the vehicle body (3) is to return while traveling autonomously.', '11. A base station to which a work vehicle is to return after the work vehicle performs work while traveling autonomously, the base station being  characterized by : at least one shower unit (31) configured to spray water onto a work unit (25) that is provided in the work vehicle (1) and to perform work on a work target; at least one air blower unit (32) configured to blow air onto the work unit (25) after the shower unit (31) sprays water; a return detection unit (33) configured to detect a return of the work vehicle (1); and a control unit (34) configured to perform control such that the work unit (25) is immediately cleaned by operation of the shower unit (31) and the air blower unit (32) when the return detection unit (33) detects the return of the work vehicle (1).', '12. The base station according to claim 11,  characterized by : a second captured image acquisition unit (35) configured to acquire a captured image that shows the work unit (25) of the work vehicle (1) after returning; a diagnosis unit (36) configured to determine a constituent component of the work unit (25) that requires replacement, based on the captured image acquired by the second captured image acquisition unit (35); and an announcement unit (37) configured to announce a determination result from the diagnosis unit (36) to a user.']
