Abstract
A work vehicle includes: an imaging device that captures an image in which a work target is shown; an image transmission unit that transmits the image captured by the imaging device to a control device; an operation signal reception unit that receives an operation signal from the control device; and an operation control unit that limits the operation signal according to a transmission status of the image.
Claims3
A work vehicle including a swing body that supports a work equipment comprising:
- an imaging device provided on the swing body that captures an image in which a work target is shown;
- and
- a processor that includes;
- an image transmission unit that transmits the image captured by the imaging device to a control device;
- an operation signal reception unit that receives an operation signal from the control device;
- and
- an operation control unit that limits an operation amount of the operation signal received according to a transmission status of the image:
- a return image reception unit that receives the image returned from the control device;
- and
- a transmission status specifying unit that specifies the transmission status based on the image transmitted by the image transmission unit and the image received by the return image reception unit,
- wherein the transmission status specifying unit specifies the transmission status based on a difference between a transmission time of the image and a reception time of the image.
A control device of a remote operation room comprising:
- a processor that includes;
- an image reception unit that receives an image from a work vehicle including an imaging device;
- a display unit that displays the image;
- an operation signal input unit that receives an input of an operation signal of the work vehicle;
- and
- an operation signal transmission unit that limits an operation amount of the operation signal according to a transmission status of the image and transmits the operation signal to the work vehicle:
- a return image reception unit that receives the image returned from the work vehicle;
- and
- a transmission status specifying unit that specifies the transmission status based on the image transmitted by the image transmission unit and the image received by the return image reception unit,
- wherein the transmission status specifying unit specifies the transmission status based on a difference between a transmission time of the image and a reception time of the image.
A method for controlling a work vehicle, the method comprising the steps of:
- capturing an image in which a work target is shown by the work vehicle;
- transmitting the captured image to a control device;
- receiving an operation signal from the control device;
- controlling the work vehicle by limiting an operation amount of the operation signal received according to a transmission status of the image;
- receiving the image returned from the control device;
- and
- specifying the transmission status based on the image transmitted and the image received,
- wherein the transmission status is based on a difference between a transmission time of the image and a reception time of the image.
