Management system for work machine, management method for work machine, and work machine

A management system for a work machine, comprising:

• a work machine that has a communication terminal device with a communication function, a power source supplying power to the communication terminal device, a switch interposed between the power source and the communication terminal device, and a location detection device acquiring location information;
• and
• a management device that is capable of communication with the communication terminal device and transmits to the communication terminal device a request instruction containing location information on a region relating to transport destination of the work machine, the request instruction being for execution of a process for enabling the communication, wherein
• when the communication terminal device receives the request instruction from the management device, the communication terminal device acquires current location information on the work machine from the location detection device,
• when the communication terminal device determines that the work machine is located in a predetermined area of the transport destination from the current location information and the location information contained in the request instruction, the communication terminal device continues to receive power supply from the power source until after a lapse of a predetermined period of time since the switch turns from an on position to an off position, and executes the process for enabling communication with the management device before a lapse of the predetermined period of time.

• a switch interposed between the power source and the communication terminal device;
• and
• a location detection device acquiring location information, wherein
• when the communication terminal device receives a request instruction containing location information on transport destination of the work machine, the request instruction being for execution of a process for enabling communication with the management device from the management device, the communication terminal device acquires current location information on the work machine from the location detection device, and
• when the communication terminal device determines that the work machine is located in a predetermined area of the transport destination from the current location information and the location information contained in the request instruction, the communication terminal device continues to receive power supply from the power source until after a lapse of a predetermined period of time since the switch turns from an on position to an off position, and executes the process for enabling communication with the management device before a lapse of the predetermined period of time.
