<p>PROBLEM TO BE SOLVED: To easily obtain detail information that data collected at every controller in construction machines are collated with one another without troublesome communication processing. SOLUTION: A plurality of on-board controllers 6, 7, 4 are installed in construction machines. These controllers are communicably connected to each other by serial communication circuits 11 through which they communicate with each other on the basis of a specified communication protocol. A controller 1 for information control in a construction machine is provided. Further, a monitor station 19 controlling relational information to at least one or more construction machines including the construction machine is installed at the outside of the construction machine. The serial communication circuits 11 in the construction machines are communicably connected to the monitor station 19 through the controller 1 for information control. Data obtained from each of a plurality of on-board controller 6, 7, 4, etc., is collected and processed, and stored in the controller for information control and the stored data are transmitted to the monitor station 19.</p> |
