Abstract
A data management device of a construction machine comprises a computing function for computing service meter time, a nonvolatile storage function for storing the computed data, and a transmission function for transmitting the data stored in the storage function to a monitor panel, while a monitor panel has a nonvolatile storage function for storing the data received from the data management device as backup data. With this configuration, a data management system for the construction machine which comprises the data management device and the monitor panel can reliably insure service meter time and other data even if a failure occurs to the data management device.
