Claims (3)

  1. A work machine management system (1000) comprising: an acquisition unit (40) configured to acquire posture information indicating a posture of a driver of a work machine (100) when boarding and alighting; a transmission unit (31) configured to transmit the posture information to an outside of the work machine (100); a determination unit (211,212) configured to determine appropriateness of the posture when boarding and alighting based on the received posture information; and a notification processing unit (213) configured to perform notification processing based on the appropriateness of the posture when boarding and alighting, characterized in that the appropriateness of the posture when boarding and alighting is determined by whether or not the posture is one of a posture in which a body is supported with three or more of four limbs, a posture in which a direction of the body is directed toward an inside of a cabin (10), and a posture in which a handrail provided in the cabin (10) is grasped.
  2. The work machine management system (1000) according to claim 1, wherein the notification processing performed by the notification processing unit (213) is at least any one of notification of occurrence of an inappropriate posture when boarding and alighting, processing of recording the occurrence of the inappropriate posture when boarding and alighting as a log, or processing of transmitting appropriateness information indicating the appropriateness of the posture when boarding and alighting.
  3. A work machine (100A) comprising: an acquisition unit (40) configured to acquire posture information indicating a posture of a driver of the work machine (100A) when boarding and alighting; a determination unit (33,34) configured to determine appropriateness of the posture when boarding and alighting based on the received posture information; and a notification processing unit (32) configured to perform notification processing based on the appropriateness of the posture when boarding and alighting, characterized in that the appropriateness of the posture when boarding and alighting is determined by whether or not the posture is one of a posture in which a body is supported with three or more of four limbs, a posture in which a direction of the body is directed toward an inside of a cabin (10), and a posture in which a handrail provided in the cabin (10) is grasped.

Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a work machine management system and a work machine. Description of Related Art In order to allow a driver of a work machine to board and alight properly, conventionally, a step-shaped elevating device leading to a driving seat has been mounted (for example, refer to Japanese Unexamined Patent Publication No. 2022-85194). In addition, United States Patent No. 2022/316179 discloses a work vehicle including an operating lever configured to operate a work implement, an actuator configured to move the operating lever, and a control section configured to control the actuator to move the operating lever to a retreat position outside an operation range of the operating lever. SUMMARY OF THE INVENTION However, the elevating device may cause an increase in size, complexity, weight, manufacturing cost, and the like of a work machine. An object of the present invention is to suppress addition of configurations and to make boarding and alighting of a driver of a work machine appropriate. According too the present invention a work machine management system according to claim 1 and a work machine according to claim 3 are provided. According to the present invention, it is possible to suppress addition of configurations and to make boarding and alighting of the driver of the work machine appropriate. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side view of an excavator of a management system according to a first embodiment.FIG. 2 is a block diagram showing a schematic configuration of the excavator management system.FIG. 3 is a view of an inside of a cabin as viewed forward from a driving seat.FIG. 4 shows an image for one frame obtained by capturing an image of an operator boarding and alighting.FIG. 5 is an explanatory diagram that visually represents a skeleton of the operator detected from the image of FIG. 4.FIG. 6 is a flowchart showing processing performed by a controller of the excavator in a series of processing from acquisition of posture information to notification.FIG. 7 is a flowchart showing processing performed by a control unit of a management device in the series of the processing from the acquisition of the posture information to the notification.FIG. 8 is a block diagram showing a schematic configuration of a management system according to a second embodiment.FIG. 9 is a flowchart showing a series of processing from acquisition of posture information to notification performed by a controller of an excavator. DETAILED DESCRIPTION OF THE INVENTION [First Embodiment] Hereinafter, a first embodiment of the present invention will be described in detail with reference to the drawings. In the present embodiment, a management system of an excavator as a work machine will be exemplified. FIG. 1 is a side view of an excavator 100, and FIG. 2 is a block diagram showing a schematic configuration of an excavator management system 1000. As shown in this diagram, the excavator management system 1000 is configured of the excavator 100 and a management device 200 that can communicate with each other through a network NW. The above-described management system 1000 may include a plurality of excavators 100. [Excavator Configuration] As shown in FIG. 1, the excavator 100 includes a lower traveling body 1; a rotating platform 3 that is turnably mounted on the lower traveling body 1 via a turning mechanism 2; a boom 4, an arm 5, and a bucket 6 as an attachment 11; and a cabin 10 as a driving seat that an operator OP as a driver boards. The attachment 11 is not limited thereto as long as a work element (for example, bucket, crusher, or crane device) is provided. The lower traveling body 1 includes, for example, a pair of right and left crawlers, and each crawler is hydraulically driven by a traveling hydraulic motor (not shown) to cause the excavator 100 to travel. The rotating platform 3 is driven by a turning hydraulic motor, an electric motor (both not shown), or the like to turn with respect to the lower traveling body 1. The boom 4 is pivotally attached to a center of a front portion of the rotating platform 3 so as to be capable of being elevated, the arm 5 is pivotally attached to a tip of the boom 4 so as to be capable of rotating up and down, and the bucket 6 is pivotally attached to a tip of the arm 5 so as to be capable of rotating up and down. The boom 4, the arm 5, and the bucket 6 are hydraulically driven by a boom cylinder 7, an arm cylinder 8, and a bucket cylinder 9, respectively. The cabin 10 is a cab that the operator boards, and is mounted on, for example, a left side of the front portion of the rotating platform 3. The excavator 100 causes an actuator to operate in response to a manipulation of the operator boarding the cabin 10 to drive driven elements such as the lower traveling body 1, the rotating platform 3, the boom 4, the arm 5, and the bucket 6. As shown in FIG. 1, in addition to the above-described configuration
