A plurality of on-board controllers are provided within a construction machine. The plurality of on-board controllers are connected with freedom to communicate with each other by means of a serial communications line allowing communications in accordance with a predetermined communications protocol. Also, an information management controller which manages information about the inside of the construction machine is provided. Further, a monitoring station which mmanages information relating to at least one construction machine including the construction machine is provided on the outside of the construction machine. Also, the serial communications line inside the construction machine and the monitoring station are connected with freedom to communicate with each other via the information management controller. Data acquired by the plurality of on-board controllers is gathered, processed and stored by the information management controller, and the stored data is sent to the monitoring station. In this way, detailed information obtained by collating data gathered by each of the different controllers in the construction machine can be easily acquired without the need for complicated communications processing.
