  The control unit 24 includes a display unit 241 in terms of functional concept. The display unit 241 is a display unit that displays disaster prevention information on the fire door. The processing performed by each unit of the control unit 24 will be described later.

(processing)
Next, the display process configured as described above and executed by the display system 2 will be described. FIG. 5 is a flowchart of the display process (in the following description of each process, step is abbreviated as “S”). Drawing 6 is a figure which illustrated disaster prevention information displayed on a door part, (a) is an illustration of disaster prevention information displayed on the surface of a door part, and (b) is displayed on the back of a door part. It is an example of disaster prevention information. The “display process” is a process for displaying disaster prevention information on the door portion 11. The timing for executing this display processing is arbitrary. For example, when the display system 2 is turned on, the execution is started and repeated, and the description will be made from the start of execution. Here, for example, in the case of a non-fire as in the prior art, the door 11 is fixed in an open state as shown in FIG. 1 by holding the locking projection 212a of FIG. Explain that it is.

  In SA1 of FIG. 5, the display unit 241 determines whether or not the door unit 11 is closed. Specifically, for example, in the same manner as in the past, when a fire is determined by an arbitrary method on the disaster prevention receiver side (not shown), the disaster prevention receiver releases the lock mechanism 13 in FIG. When the signal is transmitted, the lock mechanism 13 is configured to release the locking protrusion 212a (that is, stop holding) and the door 11 is configured to be closed as shown in FIG. Moreover, it processes as follows as it is comprised so that the cancellation | release signal from a disaster prevention receiver may be transmitted also to the display system 2. FIG. Specifically, the display unit 241 in FIG. 4 determines that the fire is not occurring and the door unit 11 is not closed when the release signal is not received via the communication unit 22 (NO in SA1). The SA1 is repeatedly executed until it is determined that the door portion 11 is closed. When a release signal is received via the communication unit 22, it is determined that a fire has occurred and the door unit 11 is closed (YES in SA1), and the process proceeds 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 before, and the lock mechanism 13 in FIG. The protrusion 212a is released, and the door 11 is closed. Moreover, the said cancellation | release signal will also be transmitted to the display system 2 side, and since the display system 2 receives a cancellation | release signal, it will determine with the time of a fire outbreak and the door part 11 having been closed.

  In SA2 of FIG. 5, the display unit 241 starts displaying disaster prevention information. Specifically, 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 transmission to the room-side projector 211 and the second room-side projector 212, the first room-side projector 211 and the second room-side projector 212 project the disaster prevention information onto the door 11, and display is started.

  Here, for example, as shown in FIG. 6A, “fire occurrence” corresponding to the fire alarm information, “fire door” and “closed” corresponding to the fire door recognition information, and the operation method of the fire door are specified. Display is started by projecting “push and open”, which is operation method specifying information, onto the surface 111 by the second room side projector 212 as disaster prevention information. Further, for example, as shown in FIG. 6B, “fire occurrence” corresponding to the fire alarm information, “fire door” and “closed” corresponding to the fire door recognition information, and the operation method of the fire door are specified. The display starts by projecting “open by pulling”, which is operation method specifying information, as the disaster prevention information on the back surface 112 by the first room side projector 211. When processed in this way, the user of the first room R1 or the second room R2 visually confirms the disaster prevention information displayed on the door part 11, and then closes the door part 11 after grasping the occurrence of a fire. You can evacuate without passing through the opening 301 in the state, or you can evacuate through the opening 301 by manually opening the door 11, so it is quick and qualified by your own site judgment It is possible to evacuate.

  In SA3 of FIG. 5, the display unit 241 determines whether or not to stop displaying the disaster prevention information. Specifically, for example, as in the conventional case, when a recovery operation is performed on a disaster prevention receiver (not shown), a recovery signal is transmitted to the display system 2. As a matter of course, the following processing is performed. Specifically, the display unit 241 in FIG. 4 determines that the display of the disaster prevention information is not terminated when it determines that the fire extinguisher is not extinguished when it does not receive the recovery signal via the communication unit 22 ( SA3 is repeatedly executed until it is determined that the display of the disaster prevention information is terminated. If a 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 to be terminated (YES in SA3), and the process proceeds to SA4. Here, for example, when a recovery operation is performed on the disaster prevention receiver (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 determined that the display of disaster prevention information will be terminated.

  In SA4 of FIG. 5, the display unit 241 ends the display of the disaster prevention information. Specifically, for example, the display of the disaster prevention information is ended by ending the projection by the first room side projector 211 and the second room side projector 212 of FIG. When processed in this way, the disaster prevention information displayed on the door portion 11 will disappear. For example, an administrator who opens the door portion 11 for restoration after a fire extinguishes visually recognizes the disaster prevention information and misidentifies a fire. It is possible to prevent this. This ends the display process.

(Effect of embodiment)
Thus, according to this Embodiment, by displaying disaster prevention information on the door part 11, for example, even if the opening part 301 is closed in the door part 11, a user can visually recognize disaster prevention information. Therefore, it is possible to increase information to be given to the user through vision, and it is possible to prevent the user from being confused and to evacuate quickly. In particular, for example, disaster prevention information becomes invisible to the user when no fire occurs, and disaster prevention information becomes visible to the user when a fire occurs, for example, to promptly evacuate when a fire occurs, When there is no fire, it is possible to prevent the confusion caused by the disaster prevention information, and it is possible to efficiently provide evacuation support and fire fighting support.

  In addition, when the fire does not occur, the disaster prevention information is not displayed on the surface 111 of the door portion 11 which is an exposed surface, and the disaster prevention information is displayed on the surface 111 when the fire occurs. Since it is possible to have a sense of unity with the surrounding environment (for example, the first room side wall portion 31), 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 recognize the occurrence of a fire, or the door 11 in a closed state can be opened and evacuated through the opening 301. Since it is possible to recognize that it is possible, it is possible to improve disaster prevention.
