  Next, the operation of the switch state notification unit 11 will be described. FIG. 6 is a flowchart showing the operation of the switch state notification unit 11 of FIG. First, the switch state notification unit 11 reads information on the state of the inspection switch 6 from the elevator control unit 7 (step S1).

  Thereafter, the switch state notifying unit 11 determines whether the state of any of the inspection switches 6 is the inspection state based on the read state information of the inspection switch 6 (step S2). ). If the switch state notification unit 11 determines in step S2 that none of the inspection switches 6 is in the inspection state, step S1 is repeated.

  On the other hand, when the switch state notification unit 11 determines that the state of any of the inspection switches 6 is the inspection state in step S2, the switch state notification unit 11 and the switch state storage unit 11 It is determined whether or not communication with the unit 17 is possible (step S3). When the switch state notification unit 11 determines that communication between the switch state notification unit 11 and the switch state storage unit 17 is possible in step S3, the switch state notification unit 11 Then, a signal indicating the state of the inspection switch 6 is sent (step S4). At this time, if the state of the inspection switch 6 is the inspection state, the switch state notification unit 11 sends an inspection state signal indicating that the state of the inspection switch 6 is the inspection state, and the state of the inspection switch 6 is If in the normal state, a normal state signal indicating that the state of the inspection switch 6 is the normal state is sent.

  Thereafter, the switch state notifying unit 11 determines whether or not all the switches in the inspection switch 6 are in the normal state (step S5). In step S5, when the switch state notifying unit 11 determines that all the switches in the inspection switch 6 are in the normal state, the process returns to step S1, while in step S5, any of the inspection switches 6 If the switch state notification unit 11 determines that the switch state is the inspection state, the process returns to step S3. Thereby, when the state of the inspection switch 6 is the inspection state, an inspection state signal is periodically sent to the switch state storage unit 17, and immediately after the state of the inspection switch 6 is switched from the inspection state to the normal state, The inspection state signal is stopped from being sent, the normal state signal is temporarily sent to the switch state storage unit 17, and then the normal state signal is stopped from being sent to the switch state storage unit 17.

  On the other hand, when the switch state notification unit 11 determines that communication between the switch state notification unit 11 and the switch state storage unit 17 is not possible in step S3, the switch state notification unit 11 Then, a signal for instructing activation of the OS unit 22 is sent. Thereby, the OS unit 22 is activated under the control of the management engine unit 25 (step S6). Thereafter, the network communication unit 12 of the elevator monitoring device 3 and the network communication unit 18 of the terminal device 4 can communicate with each other, and communication between the switch state notification unit 11 and the switch state storage unit 17 is possible ( Step S7). Thereafter, the process proceeds to step S4.

  Next, the operation of the OS stop inhibiting unit 21 will be described. FIG. 7 is a flowchart showing the operation of the OS stop inhibiting unit 21 in FIG. First, the OS stop suppression unit 21 determines whether an OS stop signal has been received from the OS stop operation unit 20 (step S11). If the OS stop suppression unit 21 determines that the OS stop signal is not received from the OS stop operation unit 20 in step S11, step S11 is repeated.

  On the other hand, when the OS stop suppression unit 21 determines that an OS stop signal is received from the OS stop operation unit 20 in step S11, the OS stop suppression unit 21 obtains information on the state of the inspection switch 6 from the switch state storage unit 17. Read (step S12).

  Thereafter, the OS stop inhibiting unit 21 determines whether or not any of the inspection switches 6 is in the inspection state (step S13). In step S13, when the OS stop suppression unit 21 determines that any of the inspection switches 6 is in the inspection state, the OS stop suppression unit 21 does not stop the OS unit 22, but for a certain period of time. A warning image is displayed on the display unit 24, and further, a warning sound is emitted from the sound generation unit 23 (step S14), and the process returns to step S1.

  On the other hand, if the OS stop suppression unit 21 determines in step S13 that all the switches in the inspection switch 6 are in the normal state, the OS stop suppression unit 21 causes the display unit 24 to display a normal image ( Then, the OS unit 22 is stopped (step S16).

  As described above, according to the warning device 1 according to the first embodiment of the present invention, the warning device 1 is used when inspecting the elevator 2 including the inspection switch 6 whose state is switched between the normal state and the inspection state. The terminal device 4 is switched from the active state to the dormant state when the check switch 6 is in the check state. When the terminal device 4 is operated as described above, the state remains in the active state, so that the inspection work is finished, the state of the inspection switch 6 remains in the inspection state, and the state of the terminal device 4 is changed from the active state. Even if the operator operates the terminal device 4 so as to switch to the dormant state, the state of the terminal device 4 remains in the active state. Accordingly, it is possible to reliably notify the operator that the state of the inspection switch 6 is in the inspection state after the inspection operation is completed.

  In addition, the terminal device 4 generates a warning sound when the terminal device 4 is operated so that the state of the inspection switch 6 is the inspection state and the state is switched from the active state to the sleep state. Therefore, when the terminal device 4 is operated so that the state of the inspection switch 6 remains in the inspection state and the state of the terminal device 4 is switched from the active state to the dormant state, the sound generation unit 23 warns. A sound is emitted, and the operator can be more surely notified that the state of the inspection switch 6 is in the inspection state.

  The terminal device 4 is a display unit that displays a warning image when the state of the inspection switch 6 is the inspection state and the terminal device 4 is operated so that the state is switched from the active state to the sleep state. 24, when the terminal device 4 is operated such that the state of the inspection switch 6 remains in the inspection state and the state of the terminal device 4 is switched from the active state to the dormant state, the display unit 24 is A warning image is displayed, and the operator can be more surely informed that the state of the inspection switch 6 is in the inspection state.

  The warning device 1 includes a switch state notification unit 11 that sends an inspection state signal to the terminal device 4 indicating that the state of the inspection switch 6 is the inspection state only when the state of the inspection switch 6 is the inspection state. Thus, when the state of the inspection switch 6 is the inspection state, the terminal device 4 can be reliably notified that the state of the inspection switch 6 is the inspection state.

  Further, since the switch state notification unit 11 periodically sends the inspection state signal to the terminal device 4, even if communication between the switch state notification unit 11 and the terminal device 4 is temporarily disabled, After the communication between the switch state notification unit 11 and the terminal device 4 is recovered, the terminal device 4 can be reliably notified that the state of the inspection switch 6 is the inspection state.

  Further, the switch state notification unit 11 sends a normal state signal indicating that the state of the inspection switch 6 is the normal state to the terminal device 4 only when the state of the inspection switch 6 is the normal state. It is possible to reliably notify the terminal device 4 that the switch 6 is in the normal state.

  In addition, since the switch state notification unit 11 temporarily sends a normal state signal, it is prevented that the normal state signal is continuously sent to the terminal device 4 after the state of the inspection switch 6 returns to the normal state. The

  Further, the terminal device 4 is a case where the state of the terminal device 4 is in the dormant state, and when the state of the inspection switch 6 is the inspection state, the state is switched from the dormant state to the active state. If the inspection switch 6 is operated so that the state of the inspection switch 6 becomes the inspection state while the device 4 is in the inactive state, the state of the terminal device 4 is switched from the inactive state to the active state. Thus, the operator can be surely notified that the inspection switch 6 is in the inspection state.
