DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings as appropriate. The figures are only shown schematically to provide a thorough understanding of the invention. Therefore, the present invention is not limited to the illustrated example. In each figure, common or similar components are denoted by the same reference numerals, and their overlapping explanations will be omitted.

[composition]
FIG. 1 is an external perspective view of a vibrating roller to which the display system of this embodiment is applied. The vibrating roller 1 is a construction machine that operates automatically at a construction site. The display system of this embodiment is a system for displaying the automation state of the vibrating roller 1. The display system of this embodiment includes an information terminal 2 (automatic operation control section), an LED control device 3 (display control section), a power source 4, and an LED tube 5 (display device). The information terminal 2 is a computer mounted on the vibrating roller 1. The information terminal 2 controls automatic operation of the vibrating roller 1. The information terminal 2 is connected to a management device (not shown) that manages construction machines that operate automatically at a construction site so as to be able to communicate by wireless or the like. The information terminal 2 controls automatic operation of the vibrating roller 1 according to commands received from the management device (operation by the operator of the management device). The LED control device 3 is a device that controls the LED tube 5. The LED control device 3 is disposed in the cabin 6 of the vibrating roller 1, and is communicably connected to the information terminal 2 by wire or the like. The LED control device 3 controls the light emission of the LED tube 5 based on the control of the information terminal 2.
Note that the information terminal 2 and the LED control device 3 constitute a control device 10.

The power source 4 is a device that supplies power to the LED control device 3 and the LED tube 5. The power source 4 is disposed in the cabin 6 of the vibrating roller 1, and is electrically connected to the LED control device 3 and the LED tube 5 via a cable or the like. The LED tube 5 is a device that displays the operating mode of the vibrating roller 1. The LED tube 5 is disposed in the cabin 6 of the vibrating roller 1, and is electrically connected to the LED control device 3 and power source 4 via a cable or the like. The LED tube 5 can emit light of at least three different colors.

The information terminal 2 includes hardware such as an input section, an output section, a control section, and a storage section. For example, when the control section is composed of a CPU (Central Processing Unit), information processing by a computer including the control section is realized by program execution processing by the CPU. Further, a storage unit included in the computer stores various programs for realizing the functions of the computer according to instructions from the CPU. This allows software and hardware to work together. The program can be provided by being recorded on a recording medium or via a network.

(driving mode)
There are three types of operation modes in automatic operation of the vibrating roller 1: during automatic operation, during automatic operation pause, and during manned operation. "Automatically operating" is an operating mode indicating that the vibrating roller 1 is operating unmanned. The "automatic operation" operation mode is activated when the operator of the management device performs a start operation, and the vibrating roller 1 travels along a preset route. "Automatic operation temporarily stopped" is an operation mode indicating that automatic operation of the unmanned vibrating roller 1 is effective, but the operation is interrupted. The "automatic operation temporarily stopped" operation mode is activated when the operator of the management device performs a temporary stop operation, and the vibrating roller 1 interrupts running. Further, the "automatic operation temporarily stopped" operation mode is terminated when the operator of the management device performs a restart operation, and the vibrating roller 1 resumes running. "During manned operation" is an operation mode indicating that the vibrating roller 1 is being operated by a man. The "manned operation" operation mode is activated when the engine of the vibrating roller 1 is started by an operator on board, regardless of whether the vibrating roller 1 is running or not.

The information terminal 2 determines whether the operating mode of the vibrating roller 1 in operation is automatic operation, temporary suspension of automatic operation, or manned operation. The LED control device 3 causes the LED tube 5 to emit light in a color corresponding to the operating mode in accordance with the determination result of the information terminal 2. For example, when the operation mode is automatic operation, the LED control device 3 causes the LED tube 5 to emit red light. When the operation mode is in automatic operation suspension, the LED control device 3 causes the LED tube 5 to emit green light. When the operation mode is manned operation, the LED control device 3 causes the LED tube 5 to emit yellow light.

Therefore, the display system of the present embodiment provides information on the operation of the vibrating roller 1, including at least during automatic operation, during automatic operation suspension, and during manned operation, for workers working around the vibrating roller 1. mode can be displayed. Therefore, the worker can work while paying attention to the automated state of the vibrating roller 1, and can prevent a reduction in work efficiency. Furthermore, safety can be improved.
Further, since the LED tube 5 can be easily installed not only in vibrating rollers but also in all kinds of construction machines, it is possible to unify the method of displaying the automation state. As a result, the worker can easily recognize the automation state of the construction machine, even if the construction machine is equipped with a rotating light or three-color light to indicate abnormalities.

(LED tube arrangement)
As shown in FIG. 1, the LED tube 5 can be arranged along the four upper sides of the outer surface of the cabin 6 by mountain-folding the cabin 6 at a substantially right angle at the corners of the cabin 6, which is a substantially rectangular parallelepiped. In this way, the LED tube 5 can be disposed on the vibrating roller 1 so as to be visible over the entire circumferential direction around the vertical axis passing through the cabin 6. Therefore, the operating mode of the vibrating roller 1 can be displayed to a worker located in any direction with respect to the vibrating roller 1. Conventionally, with electric signage type display devices, depending on the direction of the display device, it could not be seen by the worker, and depending on the shape of the construction machinery such as the vibrating roller 1, the revolving light or tricolor light could be hidden in a blind spot and could not be seen by the worker. However, in this embodiment, such a problem does not occur.
In addition, by disposing the LED tube 5 in the cabin 6, the worker can reliably find the LED tube 5 disposed on the vibrating roller 1, so that the worker can reliably recognize the automated state of the vibrating roller 1. be able to.
Further, by using the LED tube 5, a display device can be provided regardless of the shape of the vibrating roller 1. Further, by utilizing the LED tube 5, visibility can be improved throughout the day and night. Therefore, a worker working around the vibrating roller 1 can reliably recognize the automated state of the vibrating roller 1 day and night, no matter from which direction.

[process]
FIG. 2 is a flowchart of the operation mode display process. The operation mode display process is a process for displaying the operation mode of the vibrating roller 1 to workers around the vibrating roller 1. In the operation mode display process, first, the information terminal 2 determines the operation mode of the vibrating roller 1 (step S1). Specifically, the information terminal 2 specifies the operation mode corresponding to the command received from the management device, and controls the automatic operation of the vibrating roller 1. Next, the LED control device 3 causes the LED tube 5 to emit light in a color corresponding to the driving mode determined based on the control of the information terminal 2 (step S2). Specifically, the LED control device 3 causes the LED tube 5 to emit red light when the driving mode is automatic driving, causes the LED tube 5 to emit green light when the driving mode is automatic driving paused, and causes the LED tube 5 to emit green light when the driving mode is automatic driving. During manned operation, the LED tube 5 emits yellow light. The operation mode display process is repeatedly executed while the vibrating roller 1 is operating.
