Next, the operation of this embodiment will be described with reference to FIG. FIG. 4 is a flow chart for explaining the operation of the center control device. The center control device 31 always checks the presence / absence of a report from each terminal device under its jurisdiction, and if there is a report, determines whether or not it is a containment abnormality report (step S shown in FIG. 4). ₁ ). On the other hand, the elevator control device 13 constantly controls the operation of the elevator and also monitors whether or not an abnormality has occurred. Here, when a confinement abnormality occurs in the elevator 1, the elevator control device 13 detects this and the detection signal is transmitted to the terminal device 2 via the communication i / F 214. The terminal device 2 controls the protocol conversion unit 2113, the modem 2112, and the NCU 211 under the control of the MPU 211.
A confinement abnormality signal is sent to the communication line 4 via 1.
Next, the MPU 211 uses the communication i / F 214 and the output device 1
1 is connected to the communication i / F 113, and the MPU 111 is instructed to cause the display control device 1112 to perform a necessary display on the display unit 1111, for example, “contacting the monitoring center” is displayed, and the voice conversion device 1113 is used. To the communication i / F.

The center control unit 31 inputs the signal through the NCU 3111, the modem 3112 and the protocol conversion unit 3113, and the MPU 311 determines that the input signal is the abnormal confinement signal in the above step S ₁ . Based on this determination, the MPU 311 displays the required items such as the elevator number, the terminal device number, and the building name on the display device 34 based on the abnormal signal (procedure S ₂ ), and the terminal device 2 which has transmitted the abnormal signal, Protocol converter 3113
Performs automatic dialing commands the (Step S _3), and,
The protocol conversion unit 3113 is connected to the voice conversion unit 3114, and the connection to the communication line 4 is awaited (step S ₄ ). In addition,
The monitoring staff of the monitoring center 3 sees the display of the display device 34 displayed by the processing of step S ₂ and contacts the sales office that manages the elevator to perform necessary treatment such as dispatching a technician.

In the above state, when the terminal device 2 is connected by the communication line 4, the center direct-talking device 32 of the monitoring center 3 and the speaker 12a and the microphone 12b of the elevator 1 are connected, and the monitoring is performed. The supervisor of the center 3 inquires the passengers who are trapped by the center direct-talking device 32 via the speaker 12a in the elevator car about the state of the inside of the car, etc., and the passenger responds to the monitor by the microphone 12b, and the supervisor is urgent. Ask the technician to wait because he rushes. After such a conversation with the passenger, the observer disconnects the communication line 4 once. This disconnection of the communication line 4 is necessary because a communication line for receiving another alarm is required.

The MPU 311 determines that the communication line 4 has been disconnected (step S ₅ ), sets a timer and starts measurement for a predetermined time (for example, 5 minutes) set in advance (step S ₆ ). A clock built in the microcomputer is used as this timer, but a timer can be separately provided. The MPU 311 checks the timer to determine whether or not the predetermined time has elapsed (step S ₇ ), and when it has elapsed, stops the timer operation and resets it (step S ₈ ), and recovers the trapping abnormality. It is determined whether or not the recovery signal input at this time is input (step S ₉ ). If the recovery signal is input, the process for the abnormality is stopped and the process returns to step S ₁ .

If it is determined in step S ₉ that the restoration signal is not input, the MPU 311 returns the processing to step S ₃ ,
Once again, the terminal device 2 in which the trapping abnormality has occurred is connected to the communication line 4, and when this connection is made, the passengers are relieved by having the necessary conversation with the passengers in the elevator car again. In this way, the center direct-talking device 32 and the elevator direct-talking device 12 are automatically connected via the communication line 4 every predetermined time until the confinement abnormality is restored, and a conversation with the passenger is made each time. .

In the present embodiment, because of the above-mentioned configuration, the passengers trapped in the car are not left alone for a long time with only the mechanical display, and the passengers can have a direct conversation with the monitor every predetermined time. Therefore, it is possible to suppress anxiety and frustration, and it is possible to prevent an unexpected accident due to these anxiety and frustration.

Further, the present embodiment has the following effects not only on the side of the passengers who are confined, but also on the side of the monitoring center 3. For example, when a relatively wide area disaster such as an earthquake occurs, alerts are concentrated on the monitoring center. In this case, in the conventional device, the monitoring staff of the monitoring center 3 is chased by the response, or the confinement abnormality occurs due to the priority processing at the time of wide area disaster (for example, dispatching a technician to a hospital or the like preferentially). However, after the physical process is first completed, the subsequent check for the containment anomaly is often forgotten or neglected.
However, in this embodiment, since the surveillance staff and the passengers who are trapped are regularly connected via the communication line 4, it is possible to prevent the forgetting and leaving, and to reduce the burden on the surveillance staff. be able to.

In the above description of the embodiment, the operation of simply connecting the communication line during the second and subsequent automatic dials has been described as an example. However, before or after automatic dialing, or when the communication line is connected, the display device is displayed. It is also possible to display an appropriate display on the display 34 or a display lamp, or to notify the watchman by the buzzer of the communication line connection.

[0022]

As described above, according to the present invention, when the containment abnormality is reported from the terminal device to the monitoring center, the terminal device in which the containment abnormality occurs until the containment abnormality is recovered. Since the communication line is automatically connected at a predetermined time interval, passengers trapped in the car can have a direct conversation with the guard at every predetermined time, which makes them feel uneasy and frustrated. It is possible to suppress the occurrence of accidents and prevent unexpected accidents due to these anxiety and frustration. Further, when a relatively wide area disaster such as an earthquake occurs, the burden on the observer for the trapping abnormality can be greatly reduced.
