Abstract

An attachment management system includes a work vehicle, an attachment detachably coupled to the work vehicle including a vehicle controller, and a communication tag fixed to the attachment. The communication tag includes a tag transceiver, and a tag memory to store a tag identifier unique to the communication tag and attachment information unique to the attachment, to which the communication tag is fixed. The vehicle controller is configured or programmed to control the vehicle storage to store a new piece of combined information including the tag identifier and attachment information linked thereto in the beacon signal, unless both of the tag identifier and attachment information in the beacon signal match with the tag identifier and attachment information stored in the vehicle storage, and perform a predetermined operation based on attachment information of the new piece of combined information.

Claims38

Dependent claims

An attachment management system, comprising:

a work vehicle including a vehicle storage, a vehicle receiver, and a vehicle controller;
an attachment detachably coupled to the work vehicle;
and
at least one communication tag interchangeably fixed to the attachment and including:
a tag transceiver to communicate with the vehicle receiver through a beacon signal that is compliant with a near field communication standard;
and
a tag memory to store a tag identifier unique to the at least one communication tag and attachment information unique to the attachment, to which the at least one communication tag is fixed;
wherein
the vehicle storage is operable to store at least one piece of combined information including the tag identifier and attachment information linked thereto, the at least one piece of combined information obtained through the beacon signal which the vehicle receiver has received from the tag transceiver of the at least one communication tag;
and
the vehicle controller is configured or programmed to, when at least either one of the tag identifier and attachment information in the beacon signal which the vehicle receiver is receiving from the tag transceiver, does not match with the tag identifier and attachment information stored in the vehicle storage as the at least one piece of combined information;
control the vehicle storage to store a new piece of combined information including the tag identifier and attachment information linked thereto in the beacon signal which the vehicle receiver is receiving from the tag transceiver;
and
perform a predetermined operation based on attachment information of the new piece of combined information.

11 more elements

An attachment management system, comprising:

a work vehicle including a vehicle storage, a vehicle receiver, and a vehicle controller;
a plurality of attachments each detachably coupled to the work vehicle;
and
a plurality of communication tags, each of which is interchangeably fixed to one of the plurality of attachments, and includes:
a tag transceiver to communicate with the vehicle receiver through a beacon signal that is compliant with a near field communication standard;
and
a tag memory to store a piece of combined information including a tag identifier unique to one of the plurality of communication tags and attachment information unique to one of the plurality of attachments, to which the one of the plurality of communication tags is fixed;
wherein
the vehicle storage is operable to store a plurality of pieces of combined information, each of which includes one of the tag identifiers and one piece of attachment information linked thereto, the plurality of pieces of combined information obtained through the beacon signals which the vehicle receiver has received from the tag transceivers of the plurality of communication tags;
and
the vehicle controller is configured or programmed to, at a timing when or after one of the plurality of attachments is selected:
determine that one of the plurality of communication tags fixed on one of the plurality of attachments is changed to another of the plurality of communication tags, when the one piece of attachment information linked to one of the tag identifiers, which are obtained through one of the beacon signals received by the vehicle receiver, does not match with another piece of attachment information linked to the one of tag identifiers stored in the vehicle storage as one of the plurality of pieces of combined information;
control the vehicle storage to store a new piece of combined information containing the one of the tag identifiers and the one piece of attachment information linked thereto, in one of the beacon signals which the vehicle receiver is receiving from one of the tag transceivers of the plurality of communication tags;
and
perform a predetermined operation based on the one piece of attachment information of the new piece of combined information.
