Abstract

A communication system for a working machine includes: a first communication device configured to be attached to a working device detachably disposed on a vehicle body and to transmit, to an outward, device information relating to the working device as a broadcasting signal; and a receiving device having a receiving part configured to receive the device information transmitted in the broadcasting signal.

First claim

What is claimed is:

1. A communication system for a working machine, the working machine comprising a work vehicle and a working device detachably disposed on the work vehicle,
the communication system comprising:
a first communication device attached to the working device and configured to transmit a beacon containing device information which relates to the working device and includes identifying information identifying the working device; and
a receiving device provided on the work vehicle and configured to receive the beacon;
a second communication device provided on the work vehicle and connected to the receiving device, the second communication device being configured to transmit the device information to a mobile terminal,
wherein the mobile terminal is configured to detect position information thereof and to transmit, to a server, the device information transmitted from the second communication device along with the position information.

2. The communication system for the working machine according to claim 1 ,
wherein the first communication device has a first outputting part configured to transmit the identifying information,
and wherein the receiving device has a second outputting part connected to an in-vehicle network of the work vehicle and configured to output, to the in-vehicle network, the identifying information received by the receiving part.

3. The communication system for the working machine according to claim 2 , wherein the second communication device is connected to the in-vehicle network and is configured to obtain the identifying information outputted by the second outputting part,
wherein the second communication device has a transmitting part configured to transmit the identifying information to the mobile terminal.

4. The communication system for the working machine according to claim 3 ,
wherein the second communication device has a collecting part configured to collect a first operation information of a device mounted on the vehicle,
and wherein the transmitting part transmits the first operation information and the identifying information to the mobile terminal.

5. The communication system for the working machine according to claim 4 ,
wherein the first outputting part broadcasts the identifying information and second operation information of the working device,
wherein the receiving part receives the second operation information of the working device,
wherein the collecting part collects the first operation information and the second operation information,
and wherein the transmitting part transmits, to the mobile terminal, the first operation information, the second operation information, and the identifying information.

6. The communication system for the working machine according to claim 4 ,
wherein the second communication device has a relating part configured to relate the identifying information to the first operation information collected by the collecting part.

7. The communication system for the working machine according to claim 1 , comprising a display device configured to obtain the identifying information received by the receiving part and to display the obtained identifying information.

8. The communication system for the working machine according to claim 1 , comprising a time calculating part configured to calculate a cumulative time when having obtained each of the identifying information.

9. The communication system for the working machine according to claim 1 , comprising a time calculator provided on the work vehicle and configured to calculate an operation time while the receiving device receives the beacon from the first communication device.

10. The communication system according to claim 1 ,
wherein the first communication device is configured to transmit the beacon containing first operation information of the working device, and
wherein the second communication device is configured to collect second operation information of the work vehicle, and to transmit the beacon containing the device information including the first operation information and the second operation information.

11. The communication system for the working machine according to claim 1 , further comprising an inertial force detector attached to the working device and configured to detect vibration of the working device during operation thereof,
wherein the first communication device is configured to transmit the beacon when the inertial force detector detects the vibration of the working device.

12. A communication system for a working machine, the working machine comprising a work vehicle and a working device detachably disposed on the work vehicle,
the communication system comprising:
a first communication device attached to the working device and configured to transmit a beacon containing device information which relates to the working device and includes identifying information identifying the working device;
a receiving device provided on the work vehicle and configured to receive the beacon; and
an inertial force detector attached to the working device and configured to detect vibration of the working device during operation thereof,
wherein the first communication device is configured to transmit the beacon when the inertial force detector detects the vibration of the working device.

13. The communication system according to claim 12 ,
wherein the first communication device is configured to determine that the working device is operating when the inertial force detector detects the vibration of the working device continuously for a predetermined time or more and to transmit the beacon, and to determine that the working device is stopped when the inertial force detector detects no vibration of the working device continuously for a predetermined time and to stop transmitting the beacon.

14. A communication system for a working machine, the working machine comprising a work vehicle and a working device detachably disposed on the work vehicle,
the communication system comprising:
a first communication device attached to the working device and configured to transmit a beacon containing device information which relates to the working device and includes identifying information identifying the working device;
a receiving device provided on the work vehicle and configured to receive the beacon; and
a time calculator provided on the work vehicle and configured to calculate an operation time while the receiving device receives the beacon from the first communication device.

15. The communication system according to claim 14 ,
wherein the time calculator is configured to relate the identifying information contained in the beacon to the operation time while the receiving device receives the beacon.

16. The communication system according to claim 14 ,
wherein when the receiving device receives, within a predetermined time period, a first beacon for a first time and a second beacon for a second time longer than the first time, the time calculator is configured to relate the identifying information contained in the second beacon to the operation time while the receiving device receives the second beacon.

17. The communication system according to claim 14 ,
wherein when the receiving device receives, within a predetermined time period, a first beacon of for a first intensity and a second beacon of a second intensity greater than the first intensity, the time calculator is configured to relate the identifying information contained in the second beacon to the operation time while the receiving device receives the second b
