Wireless communication terminal device
A wireless communication terminal device for operating a work vehicle that autonomously travels includes: a device main body 70 having a display 74 that is capable of accepting a touch panel operation; and an emergency-stop remote controller 71 having an emergency stop button 72 that is used to stop autonomous travel of the work vehicle. The device main body 70 and the emergency-stop remote controller 71 perform wireless communication with the work vehicle via different wireless communication networks having different communication schemes, respectively.
1. A remote control system for a work vehicle provided with a machine body and a work equipment mounted on the machine body, and for operating the work vehicle that causes the work equipment to perform work while the machine body autonomously travels, comprising:
a remote control device for transmitting a control signal for controlling the machine body and the work equipment to the work vehicle by a first wireless communication method in response to a manual operation;
a stop remote controller for transmitting a stop signal for stopping the autonomous traveling of the machine body to the work vehicle by a second wireless communication method different from the first wireless communication method in response to a manual operation,
wherein the stop remote controller is configured to be able to accept only the operation related to the stop of the autonomous traveling of the machine body among controls of the work vehicle.
2. The remote control system according to claim 1 , wherein the first wireless communication method has a higher transmission speed than the second wireless communication method.
3. The remote control system according to claim 1 , wherein the work vehicle can communicate with a plurality of the stop remote controllers by the second wireless communication method.
4. The remote control system according to claim 1 , wherein a stop button image is displayed on a display unit of the remote control device, and the autonomous traveling of the machine body is stopped regardless of which of the stop remote controller or the stop button image is operated.
5. The remote control system according to claim 1 , wherein an image of surroundings of the work vehicle captured by an obstacle sensor and a camera mounted on the work vehicle is displayed on a display unit of the remote control device.
6. An autonomous traveling operation system, comprising: the remote control system according to claim 1 ; and the work vehicle.
7. A remote control system for a work vehicle that includes a machine body and a work equipment attached to the machine body, and causes the work equipment to perform work while causing the machine body to autonomously travel, the system comprising:
a remote control device that transmits a control instruction signal for controlling the machine body and the work equipment to the work vehicle using a first wireless communication method in response to a manual operation; and
a stop remote controller that transmits a stop instruction signal for stopping the autonomous travelling of the machine body to the work vehicle using a second wireless communication method different from the first wireless communication method in response to a manual operation,
wherein the stop remote controller is configured to be able to receive an operation to start wireless communication with the work vehicle and an operation to stop autonomous travel of the machine body.
