The roll blind includes a screen disposed on an inside of the top window, and a winding device disposed inside the ceiling part on a rear side of the top window. The winding device is configured to wind up the screen. The first duct is disposed inside the ceiling part. The first duct passes below the winding device. The louver disposed further to a front side than the winding device and in a first air outlet of the first duct.
A work machine includes a vehicle body, a support member, a blade, a rotation angle sensor, an object sensor, and a controller. The support member is connected to the vehicle body. The blade is rotatably supported by the support member. The rotation angle sensor detects a rotation angle of the blade. The object sensor detects an object around the work machine and outputs a signal indicating a presence or absence of the object. The controller is configured to set a detection range around the work machine. The controller is configured to determine the presence or absence of the object within the detection range based on the signal from the object sensor. The controller is configured to set the detection range according to the rotation angle of the blade.
A work machine includes a vehicle body, a work implement movably supported relative to the vehicle body, an actuator connected to the work implement, and a controller. The actuator is configured to cause the work implement to move. The controller is configured to perform an automatic control to control the actuator so that a height of the work implement in a gravity direction is maintained even when a posture of the vehicle body changes, determine whether the work machine is in a non-working state in which the work machine does not perform work with the work implement, and stop the automatic control when the work machine is in the non-working state.
A control system 1 of a work vehicle comprises: an image-capture device 128 for capturing an image of a site where construction is performed by a work vehicle provided with a work machine; a communication device 129 for transmitting the image captured by the image-capture device 128 to a remote operation room from which the work vehicle is remotely operated; a display control unit 221 for displaying the image on a display device 200 provided in the remote operation room; a transmission status detection unit 11 for detecting the transmission status of data between the work vehicle and the remote operation room; a work state detection unit 12 for detecting the work state of the work vehicle; a work continuation determination unit 15 for determining whether to continue work of the work vehicle on the basis of the transmission status and the work state; and a work machine control unit 17 for performing control to cause the work vehicle to continue the work when it is determined by the work continuation determination unit 15 that the work is to be continued.
