Description

This disclosure relates to a remote excavator control device and a remote excavator management system. Conventionally, there is a known technology that allows users to understand the status of multiple work machines operating in a designated area by displaying an indicator image that corresponds to the location of the work machines within the designated area and clearly shows the current operating state among multiple operating states that can be selected or replaced by the work machines. Japanese Patent Publication No. 2023-83265 This figure shows an example of the system configuration of a remote excavator management system.This diagram illustrates the hardware configuration of each device in the remote excavator management system.This diagram illustrates the functions of each device in the remote excavator management system.This figure shows an example of a construction plan information storage unit.This figure shows an example of an operator information storage unit.This figure shows an example of a reservation information storage unit.This figure shows an example of a proficiency level memory unit.This is the first sequence diagram illustrating the operation of the remote excavator management system.This is the second sequence diagram illustrating the operation of the remote excavator management system.This figure shows an example of a list screen for work sites.This figure shows an example of a reservation status screen. The remote excavator management system of this embodiment will be described below with reference to the drawings. Figure 1 illustrates the excavator 100 as an example of a work machine in this embodiment. The remote excavator management system SYS of this embodiment includes an excavator 100, a control device 200, a support device 300, and a remote control room RC. In the following description, the remote excavator management system SYS will be simply referred to as the management system SYS. In the management system SYS of this embodiment, the excavator 100, the control device 200, the support device 300, and the remote control room RC are connected via a network or the like. In the management system SYS of this embodiment, the management device 200 receives reservations for the operation time of the excavator 100 from the operator OP. Furthermore, in the management system SYS, the management device 200 displays the reservation status of the excavator 100's operation time for each work site on a support device 300 or the like held by the operator OP. The support device 300 is an example of a display device. In this embodiment, by doing so, operators with free schedules can be made aware of shovels 100 that do not have an assigned operator and are not scheduled to be operated, thereby improving the operational efficiency of shovels 100. First, the configuration of the excavator 100 in this embodiment will be described. Figure 1 shows a side view of the excavator 100. The excavator 100 has a lower traveling body 1, a slewing mechanism 2, and an upper slewing body 3. In the excavator 100, the upper slewing body 3 is rotatably mounted on the lower traveling body 1 via the slewing mechanism 2. A boom 4 is attached to the upper slewing body 3. An arm 5 is attached to the tip of the boom 4, and a bucket 6, which serves as an end attachment, is attached to the tip of the arm 5. The boom 4, arm 5, and bucket 6 constitute an excavation attachment as an example of an attachment. The boom 4 is driven by the boom cylinder 7, the arm 5 by the arm cylinder 8, and the bucket 6 by the bucket cylinder 9. A boom angle sensor S1 is attached to the boom 4, an arm angle sensor S2 is attached to the arm 5, and a bucket angle sensor S3 is attached to the bucket 6. The boom angle sensor S1 is configured to detect the rotation angle of the boom 4. In this embodiment, the boom angle sensor S1 is an acceleration sensor and can detect the rotation angle of the boom 4 relative to the upper slewing body 3 (hereinafter referred to as "boom angle"). The boom angle is, for example, at its minimum when the boom 4 is at its lowest position, and increases as the boom 4 is raised. The arm angle sensor S2 is configured to detect the rotation angle of the arm 5. In this embodiment, the arm angle sensor S2 is an acceleration sensor and can detect the rotation angle of the arm 5 relative to the boom 4 (hereinafter referred to as "arm angle"). The arm angle is smallest when the arm 5 is fully closed, for example, and increases as the arm 5 is opened. The bucket angle sensor S3 is configured to detect the rotation angle of the bucket 6. In this embodiment, the bucket angle sensor S3 is an acceleration sensor and can detect the rotation angle of the bucket 6 relative to the arm 5 (hereinafter referred to as "bucket angle"). The bucket angle is smallest when the bucket 6 is fully closed, for example, and increases as the bucket 6 is opened. The boom angle sensor S1, arm angle sensor S2, and bucket angle sensor S3 may each be a p
