  A liquid crystal display screen 111, a liquid crystal display screen control unit 136, and a first cooling fan 132a are disposed in the upper opening 133a. The liquid crystal display screen control unit 136 controls the liquid crystal display screen 111 to display an image / moving image on the liquid crystal display screen 111. The first cooling fan 132a cools the liquid crystal display screen 111 and the liquid crystal display screen control unit 136 by moving the outside air taken in from the vent 131 upward. Further, a beam 138 is attached to the inside of the main body 110. By attaching the liquid crystal display screen control unit 136 to the beam 138, the liquid crystal display screen 111 and the liquid crystal display screen control unit 136 are arranged side by side in the X-axis direction. The space inside the main body 110 is efficiently used.

  A power supply 135, a control unit 137, and a storage unit 141 are disposed in the lower opening 133b. The power supply unit 135 receives power from the external power supply 150 (see FIG. 4), and mainly supplies power to the control unit 137. The control unit 137 mainly controls the liquid crystal display screen control unit 136 to control the selection of images / moving images displayed on the liquid crystal display screen 111, the order in which the images / moving images are displayed, the display interval of the images / moving images, and the like. . Data for creating a screen to be displayed on the liquid crystal display screen 111 is stored in the storage unit 141.

  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 the generator is used to move the construction equipment at the construction site, the construction site digital signage apparatus 100 installed at the construction site can easily obtain power 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 storage unit 141, the GPS (Global Positioning System) reception unit 142, the first communication unit 139, the first cooling fan 132a, and the second cooling fan 132b. doing.

  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 storage unit 141 is connected to the control unit 137, and information such as moving images and images to be displayed on the liquid crystal display screen 111, temperature information measured by the temperature measurement unit 140, disaster information and evacuation information described later, and the like. Various data are stored.

  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 images stored in the storage unit 141. The control unit 137 controls the selection of an image / moving image to be displayed and the display time of the image / moving image.

  The first communication unit 139 is arranged inside the main body 110 as a communication unit for transmitting and receiving information mainly by wireless communication between the inside and the outside of the main body 110. Although the communication unit is not shown in FIG. 3B, it can be arranged in the upper opening 133a or the lower opening 133b. The first communication unit 139 can receive the disaster information 151 and the evacuation information 152 via, for example, a mobile phone line (3G) or the Internet via Wi-Fi (Wireless Fidelity). The first communication unit 139 may receive the disaster information 151 and the evacuation information 152 via satellite communication or the like.

  The GPS receiver 142 receives a GPS (Global Positioning System) signal 152 and identifies the installation location of the construction site digital signage apparatus 100 based on the GPS signal 152. The GPS receiving unit 142 may send the GPS signal 152 to the control unit 137, and the control unit 137 may specify the installation site of the construction site digital signage device 100.

<Display method of disaster information and evacuation information>
FIG. 5 is a flowchart when disaster information 151 and evacuation information 152 are displayed on the liquid crystal display screen 111. The construction site digital signage apparatus 100 normally displays construction information and the like on the liquid crystal display screen 111. On the other hand, when a disaster or the like occurs or is expected to occur, a secondary disaster can be prevented by providing the passerby with the disaster information 151, the evacuation information 152, and the like. Hereinafter, a process until the construction site digital signage device 100 displays the disaster information 151 and the evacuation information 152 will be described with reference to FIG. Here, the disaster information 151 includes not only information on natural disasters such as earthquakes, typhoons and other bad weather, floods, eruptions, etc., but also natural disasters such as nuclear disasters, fires, spills of dangerous substances, etc. It also includes disaster information.

  In step S101, the GPS signal 153 is received and the installation location of the construction site digital signage apparatus 100 is confirmed. The installation site of the construction site digital signage device 100 is confirmed by the GPS receiver 142 receiving the GPS signal 152 when the construction site digital signage device 100 is activated. In addition, it is desirable to check periodically thereafter, such as every hour or every day. Further, even after receiving disaster information 151 to be described later, the GPS signal 153 may be received at any time to confirm the installation location of the construction site digital signage device 100.

  In step S102, the evacuation information 152 is confirmed. The evacuation information 152 includes information on an evacuation facility near the installation site of the construction site digital signage apparatus 100. The evacuation information 152 is, for example, the evacuation information in the vicinity of the installation site of the construction site digital signage device 100 confirmed by the first communication unit 139 connecting to the Internet or the like when the construction site digital signage device 100 is activated. Collect 152. In addition, it is desirable that the evacuation information 152 is regularly confirmed and updated to the latest information every week or every month. Further, since there is a possibility that an evacuation facility or the like may be temporarily set up in a large-scale disaster, it is desirable that the evacuation information 152 is confirmed as needed even after receiving disaster information 151 described later.

  In step S103, the disaster information 151 and the evacuation information 152 are received by the first communication unit 139. The disaster information 151 is received, for example, by receiving disaster information 151 issued by a national or local government, or by receiving disaster information 151 issued by a private company or the like. The disaster information 151 is automatically received when a disaster occurs or when there is a high possibility of a disaster. Such disaster information 151 can be received via, for example, a mobile phone line (3G), Wi-Fi (Wireless Fidelity), or the like. Also, the construction site digital signage apparatus 100 may be installed in a place where a mobile phone line, Wi-Fi, or the like cannot be used, and a mobile phone line, Wi-Fi, or the like is used due to a disaster or the like. In consideration of the case where it becomes impossible, disaster information 151 or the like may be received via satellite communication.

  The evacuation information 152 can be obtained, for example, by receiving evacuation information issued by a national or local government, or by making a contract for transmitting evacuation information with a private company or the like. For example, there is a disaster information distribution system distributed by a country called “L alert”. In addition, it is conceivable to use evacuation information providing services of mobile phone companies, disaster prevention information distributed from private weather companies, and the like. For transmission / reception of disaster prevention information, for example, a telegram method can be used in which a fixed sentence is numbered, only the number is transmitted from the server, and the construction site digital signage apparatus 100 restores the sentence to a sentence. This method is desirable because the amount of data to be transmitted is small and transmission / reception can be performed quickly.

  In step S104, it is determined whether or not it is necessary to display detailed evacuation information 152b based on the installation location of the construction site digital signage apparatus 100. The evacuation information 152 is divided into simple evacuation information 152a and detailed evacuation information 152b. Here, the simple evacuation information 152a is information for calling attention such as “Evacuation advisory is issued in XX prefecture XX city XX district”, and detailed evacuation information 152b. This is specific information for evacuation, such as where to find evacuation centers and how to get there. In determining whether or not detailed display of the evacuation information 152b is necessary, the installation location of the digital signage apparatus for construction site 100 confirmed in step S101 and the evacuation information 152 received in step S103 can be used. For example, in the case where the evacuation information 152 that “the evacuation recommendation has been issued to the XX prefecture XX city XX district” is obtained in the step S103, the digital signage apparatus 100 for the construction site confirmed in the step S101. Compared to the installation location, if the construction site digital signage device 100 is installed at a location outside the recommended evacuation area, only simple evacuation information 152a may be displayed. In addition, the digital signage device for construction sites 100 is installed in the western part of the prefecture, and evacuation advisories are issued only in specific areas in the eastern part of the prefecture far away from the western part of the prefecture. When the digital signage apparatus 100 for construction site is installed, it is conceivable that the evacuation information 152 itself is not displayed. In these cases, the process proceeds to step S105. Further, when the installation site of the construction site digital signage device 100 corresponds to an area where evacuation is recommended, it is possible to display detailed evacuation information 152b. In this case, the process proceeds to step S106.

  Further, if a private company or the like that transmits evacuation information 152 can transmit only necessary evacuation information to the installation site of the digital signage device for construction site 100, a step is performed when the digital signage device for construction site 100 receives the evacuation information 152. You may make it display the evacuation information 152 containing the detailed evacuation information 152b, without passing through the determination process of S104. In this case also, the process proceeds to step S106.

  In step S105, the disaster information 151 is displayed on the liquid crystal display screen 111. Step S105 is executed when it is determined in step S104 that it is not necessary to display detailed evacuation information 152b. The disaster information 151 can be displayed together with construction information normally displayed on a part of the liquid crystal display screen 111, for example. In addition, simple evacuation information 152a may be displayed together with the disaster information 151.

  In step S106, the communication unit attempts to collect detailed evacuation information 152b based on the installation location of the construction site digital signage device 100. Step S106 is executed when it is determined in step S104 that detailed evacuation information 152b is necessary. The detailed evacuation information 152b is collected when the first communication unit 139 is connected to the Internet or the like. If the detailed evacuation information 152b is obtained by connecting to the Internet or the like, the process proceeds to step S107, and the information is obtained. If not, the process proceeds to step S108.

  In step S107, a screen to be displayed on the liquid crystal display unit 111 is created based on the installation location of the construction site digital signage apparatus 100 and the collected detailed evacuation information 152b. In the creation of the screen, a map indicating the current position, the evacuation site, and the like is created based on the installation location of the construction site digital signage apparatus 100 and the collected detailed evacuation information 152b.

  FIG. 6A is a diagram for explaining a method of creating a drawing showing the current position. First, based on the detailed evacuation information 152b collected in step S106 and the map stored in the storage unit 141, a map 161 describing evacuation site or evacuation site information is created. A map 161 shown in FIG. 6A shows schools 161a and 161b designated as shelters. Further, a map 162 indicating the current position is created based on the information on the installation location 162a of the construction site digital signage apparatus 100 acquired in step S101. By superimposing these two maps, a map 160 showing the evacuation site and the relative position between the evacuation site and the current position is created.

  In step S108, a screen to be displayed on the liquid crystal display screen 111 is created based on the installation location of the construction site digital signage apparatus 100 and the detailed evacuation information 152b stored in the storage unit 141. The screen to be created is created by the same method as in FIG. 6A, but the map 161 and the schools 161a and 161b that are shelters are collected in step S102 and stored in the storage unit 141 in advance. It differs from step S107 in that it is created based on information.

  Step S108 is executed when detailed evacuation information 152b cannot be collected from the Internet or the like in step S106. Although the disaster information 151 and the evacuation information 152 have been received in step S103, there are cases where further information cannot be collected from the Internet or the like due to subsequent concentration of access to the Internet, large-scale power outages, or failure of communication facilities due to a disaster. Alternatively, there may be a case where the construction site digital signage apparatus 100 is originally installed in a place with a poor communication environment, and the disaster information 151 and the like are received but the detailed evacuation information 152b cannot be received. Even in such a case, the construction site digital signage apparatus 100 can display the detailed evacuation information 152b based on the data stored in the storage unit 141.

  In step S109, the screen created in step S107 or step S108 is displayed on the liquid crystal display unit 111.

  FIG. 6B is a front view of the liquid crystal display screen 111 on which disaster information 151 and detailed evacuation information 152b are displayed. On the liquid crystal display screen 111 shown in FIG. 6B, the map 160 created in step S107 or step S108 is displayed on the upper side of the screen. This map 160 shows the position of the refuge and the way to the refuge and the like, and becomes detailed evacuation information 152b. In addition, disaster information 151 and simple evacuation information 152a are displayed at the bottom of the screen. A person who sees the display of the digital signage device for construction site 100 grasps the type and state of the disaster from the disaster information 151, grasps the risk level of the current position from the simple evacuation information 152a, and provides detailed evacuation information. Based on 152b, a specific evacuation action can be taken.

  The map 160 shows the installation position 162a and one or more nearest shelters, etc., but the extent to which the route, distance, etc. from the installation position 162a to one or more nearest shelters etc. can be sufficiently understood It is desirable to display at a reduced scale. In addition, a landmark or the like as a mark may be shown between the installation position 162a and the evacuation site so that the evacuation site can be reached more reliably. When the disaster information 151 and the simple evacuation information 152a cannot be displayed on one screen, the disaster information 151 and the simple evacuation information 152a may be displayed alternately.

  If a disaster occurs or is likely to occur, evacuation may be necessary depending on the extent of the disaster. However, a person or a traveler who simply passes through the town may not know where to evacuate. Therefore, when evacuation is necessary, it is desirable to notify disaster information and provide evacuation information promptly based on the received disaster information. The construction site digital signage apparatus 100 can provide specific evacuation information for judgment to a passerby or the like in such an emergency, and can promptly evacuate.

  Moreover, the construction site is usually equipped with a generator for moving equipment necessary for the construction. Therefore, even if a power failure occurs around the construction site, the construction site digital signage device 100 can be moved by using the generator. Furthermore, even when a large-scale power outage or the like occurs due to a disaster and communication cannot be performed or the communication environment is deteriorated, the construction site digital signage device 100 can quickly provide appropriate evacuation information according to the data stored in the storage unit 141. Can be displayed.
