Abstract: A parts information management system includes: an identification device storing parts information for identifying an attached target part; a communication device acquiring parts information included in an electric wave outputted by the identification device and measuring a received strength of the electric wave; and a management apparatus managing the parts information acquired by the communication device. The management apparatus includes an installation position judgment unit that judges whether or not the target part identified by the parts information associated with the received strength is provided at a predetermined installation position based on the received strength, and a notification unit that outputs malfunction information when it is judged that the target part is not provided at the installation position.

Abstract: A communication system provided to a working vehicle includes: an information receiving unit that communicates with identification devices and receives identification information; a first area information storage that stores first area information indicating an area where use of the information receiving unit is permitted; a comparing unit that compares the first area information with second area information indicating an area where the working vehicle is used; and a communication control unit that prohibits the information receiving unit from outputting electric waves when the second area information is not included in the first area information.

Abstract: A parts information management system includes an identification device attached to a target part at an installation position and storing parts information for identifying the target part, a communication device communicating with the identification device to acquire the parts information, a transmitter transmitting acquisition information, and a management apparatus managing the received acquisition information. The parts information includes type information indicating the target part's type and unique information for distinguishing the target part from the target parts of the same type.

Abstract: An identification device that is attached to a target component and stores identification information of the target component; and a first communication device and a second communication device that wirelessly communicate with the identification device. The second communication device holds and transmits the identification information acquired by the second communication device as second-communication-device acquisition information. The first communication device includes: a first-communication-device holder that holds the identification information acquired by the first communication device and the received second-communication-device acquisition information as first-communication-device acquisition information and a first-communication-device judging unit that judges whether or not the identification information having the same contents is contained in the first-communication-device acquisition information.

Abstract: A communication system provided to a working vehicle includes: an information receiving unit that communicates with identification devices and receives identification information; a first area information storage that stores first area information indicating an area where use of the information receiving unit is permitted; a comparing unit that compares the first area information with second area information indicating an area where the working vehicle is used; and a communication control unit that prohibits the information receiving unit from outputting electric waves when the second area information is not included in the first area information.

Abstract: A identification information acquisition system provided in a working vehicle includes: a plurality of identification devices; and a plurality of communication devices that communicate with the plurality of identification devices. The plurality of communication devices include a first communication device and a second communication device, an operation of which is controlled by the first communication device. The first communication device is disposed at a first position and the second communication device is disposed at a second position in a working vehicle, a temperature at the first position being lower than a temperature at the second position.

Abstract: A communication system provided in a working vehicle includes: an identification device that stores identification information; a communication device that outputs electric waves to communicate with the identification device; an ambient temperature judging unit that judges whether or not an ambient temperature of the environment in which the identification device is disposed exceeds an operational temperature at which an operation of the identification device is ensured; and a communication controller that prohibits the communication device from outputting the electric waves when the ambient temperature judges that the ambient temperature exceeds the operational temperature.
