Document Type and Number:
Japanese Patent JP2767363
Kind Code:
B2
Abstract:
A data collection system for a driving machine for collecting data obtained at a plurality of controllers disposed within the driving machine, in which one of the plurality of controllers is used as a master controller to perform sequential polling operation over the other controllers including an external controller through a communication line. The other controller subjected to the polling transmits data obtained at its own controller to the controllers other than its own controller. The master controller continues its polling operation so long as the master controller fails to receive a response to the polling from the external controller. The master controller, when receiving the response to the polling from the external controller, judges that the external controller was connected to a connector for connection with the external controller and stops its polling operation. The external controller responded to the polling, after responding to the polling, perform sequential polling operation over the other controllers and collects data obtained at the other controllers in place of the master controller.
