Next, the operation of this embodiment will be described with reference to FIG. FIG. 4 is a flowchart illustrating the operation of the center control device. The center control device 31 constantly 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 report of a trapping abnormality (procedure S shown in FIG. 4). ₁ ). On the other hand, the elevator control device 13 constantly controls the operation of the elevator and monitors whether an abnormality has occurred. Here, when a confinement abnormality occurs in the elevator 1, the elevator controller 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.

The center control device 31 NCU3111, via the modem 3112 and a protocol conversion unit 3113 inputs the signal, MPU 311 in the above procedure S _1, it is determined that the input signal is abnormal signal confinement. With 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 ). Protocol converter 3113
To perform automatic dialing (step S ₃ ), and
The protocol converter 3113 and the voice converter 3114 are connected, and the connection to the communication line 4 is waited (step S ₄ ). In addition,
Wardens monitoring center 3 is viewing the display of the display device 34 which is displayed by the processing steps S ₂ Contact office managing the elevator to perform the necessary actions, such as to dispatch a technician.

In the above state, when the terminal device 2 is connected by the communication line 4, the center direct talk device 32 of the monitoring center 3 is connected to the speaker 12a and the microphone 12b of the elevator 1, and the monitoring is performed. The supervisor of the center 3 inquires of the passengers trapped by the center direct talking device 32 via the speaker 12a in the elevator car about the condition inside the car, etc., and the passenger responds to the supervisor by the microphone 12b, and the supervisor immediately Ask the technician to rush and wait without panic. After such a conversation with the passenger, the observer disconnects the communication line 4 once. This disconnection of the communication line 4 is because it is necessary to provide a communication line for receiving other alerts.

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) (step S ₆ ). As this timer, a clock built in the microcomputer is used, but a timer may be separately provided. MPU311 checks the timer to determine whether or not elapsed the predetermined time (Step S _7), when the elapsed, to stop the operation of the timer to reset it (Step S _8), was confined recover abnormal It is determined whether or not a recovery signal is input at this time (step S ₉ ). If a recovery signal is input, the process for the abnormality is stopped, and the process returns to step S ₁ .

[0018] If the recovery signal in step S ₉ has been determined not to be input, MPU311 returns the process to Step S _3,
The connection between the terminal device 2 in which the confinement abnormality has occurred and the communication line 4 is performed again, and when this connection is made, a necessary conversation is again performed with the passenger in the elevator car to reassure the passenger. As described above, the center direct talk apparatus 32 and the elevator direct talk apparatus 12 are automatically connected via the communication line 4 at predetermined time intervals until the confinement abnormality is recovered, and each time a conversation is made with the passenger. .

In this embodiment, since the above-mentioned configuration is adopted, the passengers trapped in the car are not left for a long time with only the mechanical display, and have a direct conversation with the observer at predetermined time intervals. This makes it possible to suppress the feeling of anxiety and frustration, thereby preventing an unexpected accident based on the feeling of anxiety and frustration.

Furthermore, the present embodiment has the following effects not only on the confined passenger side but also on the monitoring center 3 side. 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 apparatus, the monitoring staff of the monitoring center 3 is busy with the response, or the confinement abnormality occurs due to priority processing (for example, dispatching a technical staff to a hospital or the like with priority) at the time of a wide area disaster. However, after the physical processing is completed for the first time, the subsequent check for the confinement abnormality is often forgotten or neglected.
However, in the present embodiment, since the observer and the confined passenger are regularly connected via the communication line 4, the above-mentioned forgetting and neglect can be prevented, and the burden on the observer can be reduced. be able to.

In the description of the above embodiment, the operation of simply connecting the communication line at the time of the second and subsequent automatic dials has been described by way of example. An appropriate display may be provided on the display 34 or a display lamp, or a communication line connection may be notified by a buzzer to call attention of a monitor.

[0022]

As described above, according to the present invention, when a confinement error is reported from a terminal device to the monitoring center, the terminal device in which the confinement error has occurred is recovered until the confinement error is recovered. The communication line is automatically connected at predetermined time intervals, so that passengers trapped in the car can have a direct conversation with the supervisor at predetermined time intervals, thereby feeling uneasy and frustrated. And an unexpected accident based on the feeling of anxiety or frustration can be prevented. Further, when a relatively wide-area disaster such as an earthquake occurs, the burden on the supervisor for the confinement abnormality can be greatly reduced.
