It is possible. For example, if the management side does not have enough operating data (daily report) provided every 24 hours every day, and wants to know the operating status of the excavator 1 in a shorter cycle (for example, every several hours), the transmission The response can be shortened. Conversely, for example, if the daily report is not required, and the operating status should be grasped every few days to reduce the communication cost, the transmission cycle can be lengthened to respond. As described above, according to the present embodiment, the highest priority operation data can be provided flexibly in response to the needs of the management side.

- both the data recording unit 60 and the display control unit 55 have the snapshot function. That is, when the snapshot data is displayed on the display 54, the snapshot data stored in the display control unit 55 is used, and when the snapshot data is transmitted to the management side via satellite communication or when the portable terminal 71 or the like is used. When downloading, the snapshot data stored in the data recording unit 60 is used.
