(process)
Next, the display process configured in this way and executed by the display system 2 will be described. FIG. 5 is a flowchart of the display process (steps are abbreviated as “S” in the following description of each process). 6A and 6B are diagrams illustrating disaster prevention information displayed on the door portion, FIG. 6A is an example of disaster prevention information displayed on the front surface of the door portion, and FIG. 6B is an example of disaster prevention information displayed on the back surface of the door portion. This is an example of disaster prevention information to be provided. The "display process" is a process of displaying disaster prevention information on the door portion 11. The timing of executing this display process is arbitrary, but for example, it is assumed that the execution is started when the power of the display system 2 is turned on and the display process is repeatedly executed, and the description will be made from the point where the execution is started. Here, for example, in the event of a non-fire as in the conventional case, the door portion 11 is fixed in an open state as shown in FIG. 1 by holding the locking protrusion 212a of FIG. 3 by the lock mechanism 13. Explain that it is.

In SA1 of FIG. 5, the display unit 241 determines whether or not the door unit 11 is closed. Specifically, it is optional, but for example, when a fire is determined by an arbitrary method on the disaster prevention receiver side (not shown) as in the conventional case, the disaster prevention receiver releases the lock mechanism 13 of FIG. When a signal is transmitted, the locking mechanism 13 is configured to release the locking protrusion 212a (that is, to cancel the holding) so that the door 11 is closed as shown in FIG. Further, assuming that the release signal from the disaster prevention receiver is also transmitted to the display system 2, the processing is performed as follows. Specifically, the display unit 241 of FIG. 4 determines that the door unit 11 is not closed when a fire does not occur when the release signal is not received via the communication unit 22 (NO of SA1). , SA1 is repeatedly executed until it is determined that the door portion 11 is closed. Further, when the release signal is received via the communication unit 22, it is determined that the door unit 11 is closed at the time of a fire (YES in SA1), and the process shifts to SA2. Here, for example, when a fire is determined on the disaster prevention receiver side (not shown), the release signal is transmitted to the lock mechanism 13 side in the same manner as in the conventional case, and the lock mechanism 13 in FIG. 3 is for locking. The protrusion 212a is released and the door 11 is closed. Further, the release signal is also transmitted to the display system 2 side, and the display system 2 receives the release signal. Therefore, it is determined that the door portion 11 is closed at the time of a fire.

In SA2 of FIG. 5, the display unit 241 starts displaying disaster prevention information. Specifically, although it is optional, for example, it is assumed that the disaster prevention information to be displayed on the door portion 11 is recorded in the recording unit 23, the disaster prevention information is acquired, and the acquired disaster prevention information is the first in FIG. After transmitting to the room side projector 211 and the second room side projector 212, the display is started by projecting the disaster prevention information on the door portion 11 by the first room side projector 211 and the second room side projector 212.

Here, for example, as shown in FIG. 6A, the "fire outbreak" corresponding to the fire alarm information, the "fire door" and "closed" corresponding to the fire door recognition information, and the operation method of the fire door are specified. Operation method The display is started by projecting the specific information "push open" on the surface 111 by the second room side projector 212 as disaster prevention information. Further, for example, as shown in FIG. 6B, the "fire outbreak" corresponding to the fire notification information, the "fire door" and "closed" corresponding to the fire door recognition information, and the operation method of the fire door are specified. The display is started by projecting the operation method specific information "pull and open" on the back surface 112 by the first room side projector 211 as disaster prevention information. When processed in this way, the user of the first room R1 or the second room R2 closes the door portion 11 after grasping the occurrence of a fire by visually recognizing the disaster prevention information displayed on the door portion 11. You can evacuate without passing through the opening 301 in the state, or you can manually open the door 11 and evacuate through the opening 301, so you can quickly and qualify at your own site judgment. It will be possible to evacuate to.

In SA3 of FIG. 5, the display unit 241 determines whether or not to end the display of the disaster prevention information. Specifically, it is optional, but for example, as in the conventional case, when a recovery operation is performed on the disaster prevention receiver side (not shown), a recovery signal is transmitted to the display system 2. As a matter of fact, it is processed as follows. Specifically, the display unit 241 of FIG. 4 determines that the fire has not been extinguished when the recovery signal has not been received via the communication unit 22, and determines that the display of the disaster prevention information is not completed ( SA3 NO), SA3 is repeatedly executed until it is determined that the display of disaster prevention information is finished. Further, when the recovery signal is received via the communication unit 22, it is determined that the fire has been extinguished, it is determined that the display of the disaster prevention information is terminated (YES of SA3), and the process proceeds to SA4. Here, for example, when a recovery operation is performed on the disaster prevention receiver side (not shown), a recovery signal is transmitted, but since the display system 2 receives this recovery signal, it is determined that the fire has been extinguished. It is judged that the display of disaster prevention information is finished.

In SA4 of FIG. 5, the display unit 241 ends the display of disaster prevention information. Specifically, although it is arbitrary, for example, the display of the disaster prevention information is terminated by ending the projection by the first room side projector 211 and the second room side projector 212 in FIG. When processed in this way, the disaster prevention information displayed on the door portion 11 disappears. For example, an administrator who opens the door portion 11 for recovery after extinguishing the fire visually recognizes the disaster prevention information and misidentifies the fire. It is possible to prevent this from happening. This ends the display process.

(Effect of embodiment)
As described above, according to the present embodiment, by displaying the disaster prevention information on the door portion 11, the user can visually recognize the disaster prevention information even when the opening 301 is closed at the door portion 11, for example. Therefore, it is possible to increase the information given to the user through the visual sense, prevent the user from being confused, and promptly evacuate. In particular, for example, when a fire does not occur, the disaster prevention information becomes invisible to the user, and when a fire occurs, the disaster prevention information becomes visible to the user. When a fire does not occur, it is possible to prevent confusion caused by disaster prevention information, and it is possible to efficiently provide evacuation support and fire extinguishing support.

Further, by displaying the disaster prevention information on the surface 111 when a fire does not occur without displaying the disaster prevention information on the surface 111 of the door portion 11 which is an exposed surface when a fire does not occur, for example, the surface 111 can be displayed on the surface 111 of the fire door when a fire does not occur. Since it is possible to have a sense of unity with the surrounding environment (for example, the side wall portion 31 of the first room), it is possible to improve the design of the environment including the door portion 11.

Further, by displaying the fire alarm information and the fire door recognition information as disaster prevention information, for example, the user can be made to recognize the occurrence of a fire, or the door portion 11 in the closed state can be opened and evacuated through the opening 301. Since it is possible to recognize that it is possible to do so, it is possible to improve the disaster prevention property.
