System for backing up vehicle use data locally on a construction vehicle
First Claim
1. A data management system for a construction machine comprising a plurality of data management units for collecting and managing data from a plurality of working units in charge of operations related to traveling or work of the construction machine, the data management units being provided in the construction machine, whereina first data management unit comprises:
- computing means for computing data on traveling or work of a working unit in charge of the traveling or work of the construction machine based on the data collected from the working unit;
storage means for storing the data computed by the computing means; and
transmission means for transmitting the data stored in the storage means to a second data management unit, and the second data management unit comprises storage means for storing the data received from the first data management unit as backup data.

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.
