The power supply unit 135 receives power from the external power supply 150 (see FIG. 4) and supplies power to the control unit 137.

  FIG. 4 is a block diagram showing a configuration of the construction site digital signage apparatus 100. A power supply 135 disposed in the main body 110 is connected to the external power supply 150. An example of the external power supply 150 is a generator. Since a generator is used to move construction equipment at a construction site, electric power can be easily obtained from the generator. Further, instead of using the external power supply 150 or together with the external power supply 150, an internal power supply (not shown) such as a battery may be disposed in the main body 110. When an internal power supply is provided, the construction site digital signage apparatus can be used in an emergency where the external power supply 150 cannot be used.

  The control unit 137 is connected to the power source 135 and receives power supply from the power source 135. The control unit 137 is connected to the switch 117b, and activation and stop of the control unit 137 are controlled by pressing the switch 117b. The control unit 137 controls operations of the liquid crystal display screen control unit 136, the first communication unit 139, the first cooling fan 132a, and the second cooling fan 132b.

These images / moving images can be transferred to the control unit 137 by connecting a personal computer to the USB terminal, or using a CD, DVD, memory, or the like.

  The first cooling fan 132 a and the second cooling fan 132 b together with the air vent 131 constitute a cooling unit that cools the liquid crystal display screen control unit 136 and the liquid crystal display screen 111. Further, a temperature measurement unit 140 for measuring the temperature of the inside of the main body unit 110, the liquid crystal display screen control unit 136, or the control unit 137 may be disposed inside the main body unit 110. The temperature measuring unit 140 is connected to the control unit 137, and when the temperature of the inside of the main body unit 110, the liquid crystal display screen control unit 136, or the liquid crystal display screen 111 exceeds a predetermined temperature, the first cooling fan 132a and the second cooling fan 132a. When the cooling fan 132b is activated and the temperature of the inside of the main body 110, the liquid crystal display screen control unit 136, or the liquid crystal display screen 111 falls below a predetermined temperature, the first cooling fan 132a and the second cooling fan 132b are turned on. By stopping, it is possible to prevent the inside of the main body 110, the liquid crystal display screen control unit 136, or the liquid crystal display screen 111 from being overcooled and perform efficient cooling. In the construction site digital signage apparatus 100, the liquid crystal display screen control unit 136 and the liquid crystal display screen 111 may be cooled by water cooling.

  The liquid crystal display screen control unit 136 is connected to the liquid crystal display screen 111 and the control unit 137. The liquid crystal display screen control unit 136 causes the liquid crystal display screen 111 to display images / moving pictures stored in the control unit 137. The control unit 137 controls the selection of an image / moving image to be displayed and the display time of the image / moving image. Further, the liquid crystal display screen 111 may be set so that the luminance is changed by a change in brightness outside the daytime or nighttime. For example, when the outside is bright such as during the daytime, the brightness of the liquid crystal display screen 111 is increased to increase the visibility. When the outside is dark such as at night, the visibility is sufficiently ensured even if the brightness is reduced. The luminance of 111 is reduced to reduce power consumption. In this case, the brightness of the liquid crystal display screen 111 may be automatically adjusted by attaching a light / dark sensor (not shown) to the construction site digital signage device and automatically sensing the outside brightness. .

  The first communication unit 139 is disposed inside the main body 110 as a communication unit for transmitting and receiving information by wireless communication between the inside and the outside of the main body 110. Although the communication unit is not shown in FIG. 3B, the communication unit may be disposed in the upper opening 133a, the lower opening 133b, or the control unit 137. The first communication unit 139 is connected to the control unit 137 and connected to the Internet 151 by wireless communication. As a result, the operator 152 can control the control unit 137 via the Internet 151 and the first communication unit 139 without being at the construction site.

  The operator 152 can control the display of images and moving images stored in the control unit 137 by controlling the control unit 137, for example. For example, the display of images, moving images, and the like is sequentially displayed according to a predetermined program. The operator 152 can control the display by changing the program. In addition, the operator 152 can transmit a new image / moving image to the control unit 137. For example, weather information when the weather worsens, disaster information when a disaster occurs, accident information when an accident occurs, traffic information when traffic occurs, text, images, videos, etc. Then, it can be transmitted to the control unit 137 and displayed on the liquid crystal display screen 111 in real time or in a state close to real time. Further, the operator 152 may be set so that the information of the digital signage apparatus 100 for construction site can be received via the Internet 151. The received information includes, for example, temperature information of the temperature measuring unit 140, image information displayed on the liquid crystal display screen 111, and the like. Further, a thermometer, a hygrometer, a camera, or the like may be attached to the construction site digital signage apparatus 100 so that construction site information can be obtained in real time or in a state close to real time.

After the control unit 137 is activated in step S103, the temperature measurement unit 140 automatically measures the temperature inside the main body unit 110. If the measured temperature is equal to or higher than the predetermined temperature, the first cooling fan 132a and the second cooling fan 132b are activated to cool the liquid crystal display device 136 and the control unit 137.

  In step S105, an image or a moving image is displayed on the liquid crystal display screen 111. The image or moving image displayed in step S105 is an image or moving image stored in advance in the control unit 137, and is displayed in order according to a predetermined program.

  In step S106, the communication unit is connected to the Internet 151, and the data in the control unit 137 is updated. Specifically, the operator 152 accesses the control unit 137 via the Internet 151 and the first communication unit 139, changes the image display program in the control unit 137, or sends new image data / moving image data to the control unit. By adding to 137, the data of the control unit 137 is updated.

  In step S107, the updated image is displayed on the liquid crystal display screen 111. Step S106 and step S107 need not be performed if there is no problem in the initial setting state.

  In the construction site digital signage apparatus 100, as shown in FIG. 5A, the work performed by the site worker is only to connect the power source 135 to the external power source 150 and press the switch 117b. Therefore, the site worker does not need to acquire special knowledge for handling the digital signage device 100 for construction site, and a person with special knowledge for handling the digital signage device 100 for construction site can acquire digital signage for construction site. There is no need to go to the installation site of the apparatus 100. As a result, the burden on the site worker is reduced or the operation cost of the digital signage apparatus 100 for a construction site is reduced. Also, when there is only one switch 117b on the outer surface of the construction site digital signage apparatus 100, there is no doubt as to which switch should be pressed, and the switch to be pressed is not mistaken.

  FIG. 5B is a flowchart when the construction site digital signage apparatus 100 is stopped. Hereinafter, a method for stopping the construction site digital signage apparatus 100 will be described with reference to FIG.

  In step S201, the switch 117b is pressed. When the switch 117b is pressed while the control unit 137 is activated, the control unit 137 starts an operation for automatically stopping.

  In step S202, the liquid crystal display screen control unit 136 and the cooling unit are stopped. The liquid crystal display screen control unit 136 and the cooling unit are automatically stopped before the control unit 137 is completely stopped. Or you may set so that it may stop automatically after predetermined time passes.

  In step S203, the control unit 137 is stopped. The system of the control unit 137 is automatically shut down and stopped safely.

  As shown in FIG. 5 (b), when stopping the construction site digital signage apparatus 100, the site worker only presses the switch 117b. Therefore, even those who do not have special knowledge about the construction site digital signage apparatus 100 can safely stop the construction site digital signage apparatus 100.

<Configuration of digital signage device 200 for construction site>
FIG. 6A is a right side view of the construction site digital signage apparatus 200. The construction site digital signage apparatus 200 includes a main body 110 and a pedestal 220. The pedestal 220 is mainly different from the pedestal 110 in the first embodiment in the shape of the top plate. The pedestal 220 has a top plate 221 that extends from near the center of the pedestal 220 to the end on the + X axis side. A rail (not shown) extending in the X-axis direction is formed on the surface of the top plate 221 on the + Z-axis side, and the main body 110 can move on the top plate 221 in the X-axis direction along the rail. That is, the main body 110 can be moved on the top plate 221 from the vicinity of the center of the pedestal 220 to the end on the + X axis side according to the situation.

  FIG. 6B shows a construction site digital signage apparatus 200 arranged at the construction site. There are various construction sites, but for example, the temporary enclosure of a construction site such as an apartment construction site may be formed with a partially transparent temporary enclosure for lighting and crime prevention. . FIG. 6B shows such a construction site, a sidewalk adjacent to the construction site, and a transparent temporary enclosure 154A that partitions the construction site and the sidewalk. The transparent temporary enclosure 154A is supported by a framework formed by the aggregate 154B. On the construction site side, the construction site digital signage device 200 is arranged with the liquid crystal display screen 111 facing the sidewalk. Thereby, it is possible to show the outline of the construction, the progress of the construction, the predicted completion figure of the building, and the like with easy-to-understand images, videos, etc.

  For example, in the construction site digital signage device 100 shown in FIG. 1A, the pedestal 120 is positioned on the + X axis side and the −X axis side of the main body 110 in order to stably stand the construction site digital signage device 100. Overhangs. Therefore, when the construction site digital signage device is arranged at the construction site as shown in FIG. 6B, the liquid crystal display screen 111 is separated from the transparent temporary enclosure 154A, and the liquid crystal display screen 111 is viewed from the sidewalk side. Sometimes it was difficult.

  In the construction site digital signage device 200, as shown in FIG. 6B, the main body 110 is moved in the + X-axis direction on the top plate 221, and the main body 110 is moved to the + X-axis side end of the top plate 221. By moving it, the liquid crystal display screen 111 can be arranged near the transparent temporary enclosure 154A. Thereby, the liquid crystal display screen 111 can be easily seen from the sidewalk side. The construction site digital signage device 200 can be supported by, for example, connecting the eyebolt 112 and the pedestal portion 220 to the aggregate 154B and fixing them with a rope 156, for example. The construction site digital signage device 200 can be placed in a stable state by being fixed to the aggregate 154B with a rope 156 or the like, but when the main body 110 is moved to the + X axis side of the pedestal 220. Since the center of gravity of the digital signage apparatus 200 for the construction site is closer to the + X-axis side, the center of gravity is moved closer to the center of the pedestal 220 by placing a weight 153 on the −X-axis side of the pedestal 220. The on-site digital signage device 200 may be further stabilized.
