CONSTRUCTION MACHINERY, MOBILE INFORMATION TERMINAL FOR ACQUIRING OPERATION DATA FROM CONSTRUCTION MACHINERY, CONSTRUCTION MACHINERY INFORMATION COMMUNICATION SYSTEM, AND PROGRAM IMPLEMENTED ON MOBILE INFORMATION TERMINALS

摘要

In a condition where a construction machine is in operation in an area where communication means for transmitting operation data to a server is not available, processing for accumulating operation data of the construction machine in the server is executed. A vehicle-side control unit (17) determines whether long distance communication means (W) is available or not, when determining that the long distance communication means (W) is available, controls a first vehicle-side communication unit (14) so as to transmit the operation data via the long distance communication means (W), and when determining that the long distance communication means (W) is not available, causes a vehicle-side storage unit (15) to store the operation data, and further determines whether a transmission start command is received from a tablet (3) or not, and when determining that the transmission start command is received, controls a second vehicle-side communication unit (16) so as to transmit the operation data stored in the vehicle-side storage unit (15) via short distance communication means (N).
