Telematics service system

A telematics service system comprising:

• at least one working vehicle;
• at least one attachment mountable to and demountable from the at least one working vehicle;
• a transmitter provided in or on the at least one attachment to transmit a wireless signal compliant with a near field communication standard;
• a first communicator to receive the wireless signal transmitted from the transmitter;
• a second communicator to transmit attachment information including attachment identification information of the at least one attachment;
• a server to receive the attachment information transmitted from the second communicator and manage the attachment information as telematics information;
• and
• a controller to acquire the attachment identification information from the wireless signal received by the first communicator and cause the second communicator to transmit the attachment information to the server;
• wherein
• the controller is configured or programmed to:
• in response to an attachment operation to mount the at least one attachment to the at least one working vehicle or a demounting operation to demount the at least one attachment from the at least one working vehicle, determine whether the at least one attachment is in a mounted state in which the at least one attachment is considered mounted to the at least one working vehicle or in a demounted state in which the at least one attachment is considered demounted from the at least one working vehicle;
• transmit, to the server via the second communicator, the attachment information including the attachment identification information of the at least one attachment which is determined as being in the mounted state, upon determining that the at least one attachment is in the mounted state;
• and
• transmit, to the server via the second communicator, the attachment information including predetermined identification information which is predefined as the attachment identification information, upon determining that the at least one attachment is in the demounted state;
• and
• the server is configured or programmed to determine whether the at least one attachment is in the mounted state or in the demounted state based on the attachment identification information included in the attachment information transmitted from the second communicator.
