MANAGEMENT SYSTEM OF WORKING MACHINE, MANAGEMENT METHOD OF WORKING MACHINE, AND WORKING MACHINE

摘要

A management system of a working machine includes: a working machine provided with a communication terminal device having a communication function, a power source which supplies electric power to the communication terminal device, and a switch provided between the power source and the communication terminal device; and a management device which is capable of communicating with the communication terminal device, and which transmits a request command to the communication terminal device, causing the communication terminal device to execute a process making said communication possible. When the communication terminal device receives the request command from the management device, the communication terminal device enters a state in which it accepts the supply of electric power from the power source, until a pre-determined time has elapsed after the switch has been turned from an ON state to an OFF state.
