Abstract

An access point device for a work machine is configured to connect a work machine and a mobile terminal via wireless communication. The access point includes a memory, a controller, and a communicator. The memory is to store data of the work machine. The controller is to set a request as a communication identifier to be received by a mobile terminal. The mobile terminal is configured to obtain the data stored in the memory in accordance with the request. The communicator is to transmit the communication identifier to the mobile terminal and to transmit the data stored in the memory to the mobile terminal.

First claim

What is claimed is:

1. An access point device for a work machine, the access point device being configured to transmit a communication identifier that is configured to be obtained by a mobile terminal in establishing connection via wireless communication between an in-vehicle network disposed on the work machine and the mobile terminal on an outside network other than the in-vehicle network, comprising:
a memory to store data of the work machine;
a controller to newly generate another communication identifier when the data stored in the memory is updated, the other communication identifier being generated by adding, to the communication identifier, information representing request to obtain the updated data; and
a communicator to transmit the other communication identifier generated by the controller to the mobile terminal and to transmit the updated data to the mobile terminal when the mobile terminal is connected to the access point device via the wireless communication after the mobile terminal receives the other communication identifier transmitted by the communicator.

2. The access point device according to claim 1 , wherein
the controller sets the request as the communication identifier when the data in the memory is updated, and
the communicator stops the transmission of the communication identifier when the mobile terminal obtains the data in accordance with the request shown in the communication identifier after the transmission of the communication identifier.

3. The access point device according to claim 2 , wherein
the controller sets the request as the communication identifier, when the data in the memory is updated after the mobile terminal has obtained the data.

4. A communication system for a work machine, comprising:
a mobile terminal; and
an access point device to transmit a communication identifier to an in-vehicle network disposed on the work machine and to the mobile terminal on an outside network other than the in-vehicle network, the communication identifier being configured to be obtained by a mobile terminal, the access point device comprising:
a memory to store data of the work machine;
a controller to newly generate another communication identifier when the data stored in the memory is updated, the other communication identifier being generated by adding, to the communication identifier, information representing request to obtain the updated data; and
a communicator to transmit the other communication identifier generated by the controller to the mobile terminal and to transmit the updated data to the mobile terminal when the mobile terminal is connected to the access point device via the wireless communication after the mobile terminal receives the other communication identifier transmitted by the communicator.

5. An access point device for a work machine, the access point device being configured to transmit a second identifier that is configured to be obtained by a mobile terminal in establishing connection via wireless communication between an in-vehicle network disposed on the work machine and the mobile terminal on an outside network other than the in-vehicle network, comprising:
a state receiver to obtain a state of the work machine, the state receiver being disposed on the work machine;
a controller to generate a first identifier as a communication identifier to be obtained by the mobile terminal in the wireless communication, the first identifier showing the state of the work machine obtained by the state receiver; and
a communicator to separately transmit the first identifier generated by the controller and the second identifier that is a communication identifier to be obtained by the mobile terminal in the wireless communication,
wherein the communicator is configured to establish a wireless communication with the mobile terminal based on the second identifier after transmitting the first identifier generated by the controller.

6. The access point device according to claim 5 , wherein
the controller sets the first identifier when the state of the work machine changes.

7. A communication system for a work machine, comprising:
a mobile terminal on an outside network; and
an access point device being on an in-vehicle network disposed on the work machine and being configured to transmit a second identifier that is configured to be obtained by a mobile terminal in wireless communication, the access point device comprising:
a state receiver to obtain a state of the work machine, the state receiver being disposed on the work machine;
a controller to generate a first identifier as a communication identifier to be obtained by the mobile terminal in the wireless communication, the first identifier showing the state of the work machine obtained by the state receiver; and
a communicator to separately transmit the first identifier generated by the controller and the second identifier that is a communication identifier to be obtained by the mobile terminal in the wireless communication,

wherein the communicator is configured to establish a wireless communication with the mobile terminal based on the second identifier after transmitting the first identifier generated by the controller.

8. The communication system according to claim 7 , wherein
the mobile terminal includes a display to display the first identifier.

9. A work machine comprising:
an access point device being on an in-vehicle network and being configured to transmit a communication identifier to a mobile terminal in establishing connection via wireless communication;
a receiver to obtain information data outputted to an in-vehicle network of the work machine;
a controller newly to generate another communication identifier when the receiver obtains the information data, the other communication identifier being generated by adding, to the communication identifier, information corresponding to the obtained information data; and
a communicator to transmit the other communication identifier to the mobile terminal via wireless communication, the other communication identifier having been generated by the controller and including the information data.

10. The work machine according to claim 9 , wherein
the controller sets the communication identifier as an identifier showing occurrence of trouble when the information data shows the occurrence of trouble, and
the communicator transmits the communication identifier to the mobile terminal.

11. The work machine according to claim 9 , wherein
the controller sets the communication identifier as an identifier showing a shortage of material to be used in an operation for the work machine, when the information data shows the shortage of the material, and
the communicator transmits the communication identifier to the mobile terminal.

12. A communication system for a work machine, comprising:
a mobile terminal on an outside network; and
an access point device being on an in-vehicle network disposed on the work machine and being configured to transmit a communication identifier that is configured to be obtained by the mobile terminal in wireless communication, the access point device comprising:
a receiver to obtain information data outputted to the in-vehicle network;
a controller to include the obtained information data in the communication identifier when the receiver obtains the information data; and
a communicator to transmit, to the mobile terminal, the communication identifier including the information data via wireless communication, the communication identifier being generated by the controller.

13. The communication system according to claim 12 , wherein
the controller sets the co
