Description

Description: TECHNICAL FIELD The present invention relates to an emergency notification device, and more particularly, to an emergency notification device that notifies a maintenance worker who performs maintenance work of an elevator of an emergency that has occurred.

[Conventional technology]

If an accident occurs in an elevator, it may not only cause inconvenience to the passengers of the elevator, but also lead to personal injury in some cases. Maintenance work is regularly performed by maintenance personnel. A maintenance worker who performs the maintenance and inspection work is dispatched from a service company that manages the elevator and patrols the area in charge to perform the maintenance and inspection work.

This maintenance and inspection work is usually performed by one person in a machine room, in a pit, in a car or on a car, except for special work.
For this reason, if an abnormal situation occurs in which the maintenance staff becomes disturbed and feels ill and cannot perform maintenance and inspection work, the maintenance staff must report the situation to the outside on their own. It is not clear, and there is a risk that maintenance personnel will be trapped in the site of maintenance and inspection work for a long time.

Therefore, the maintenance staff carrying out the maintenance and inspection work each carry a security buzzer, and if an abnormal situation occurs for the maintenance staff themselves, the security buzzer is operated and the alarm sound of the buzzer sounds to alert the user of the abnormal situation. Outbreaks are reported outside.

[Problems to be solved by the invention]

This conventional security buzzer report
When the maintenance personnel are in the machine room, they are often noisy and do not reach the outside. It is also known that even when a maintenance person is on a car or in a pit, when the area near the landing is noisy, it is difficult to hear this notification sound outside. Further, when the security staff cannot operate the security buzzer carried by them and suddenly loses their consciousness, it is impossible to notify the outside at all.

The present invention has been made in view of the current state of emergency notification to the outside of the occurrence of abnormal situations of maintenance personnel as described above. To provide an emergency notification device that can make a notification.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a switch operated by a maintenance person who performs maintenance work on an elevator, an alarm device for notification, and an alarm device when the switch is in an operating state for a predetermined time. When the switch is in the operating state even when a predetermined time has elapsed after the alarm device is activated, a notification device for transmitting abnormal data to the emergency contact center via a telephone line is provided.

[Action]

With such a configuration, the maintenance staff operates the switch before starting the maintenance work and starts the maintenance work.
When the operation state of the switch continues for a predetermined time (for example, a time slightly shorter than the average maintenance / inspection work time), the alarm is activated by the timing completion signal of the timer. By the operation of the alarm, the maintenance person must remember to cancel the switch operation.

If the maintenance staff is affected by modulation and falls down during the maintenance and inspection work, the notification device detects that the switch is still operating after a predetermined time from the activation of the alarm. Transmits abnormal data to an emergency contact center (for example, a monitoring center) via a telephone line.

In this way, the occurrence of the abnormal situation that occurred to the maintenance staff during the maintenance and inspection work is reliably and informed to the emergency contact center.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 and FIG. 2 are views for explaining the embodiment, and FIG.
FIG. 2 is an explanatory diagram showing the overall configuration, and FIG.

An operation panel 5 is provided in the car 1, and a switch 11 and a buzzer 15 are arranged below the operation panel 5. On the car 1, a switch 10 and a corresponding buzzer 14 are mounted, and on the pit 3, a switch 12 and a corresponding buzzer 16 are mounted.

A machine room 7 is provided on the upper end side of the hoistway 2, and a control panel 8 having a notification device 17 is arranged in the machine room 7. The machine room 7 has a buzzer corresponding to the switch 9.
13 is attached, and the notification device 17 in the machine room 7 is connected via a telephone line 21 to a monitoring center 22 which is an emergency communication center.

The switch 11 and the buzzer 15 have communication lines 29 respectively.
One end of 30 is connected, and one end of communication lines 24 and 27 are connected to the switch 10 and the buzzer 14, respectively. These communication lines 24, 27, 29, 30 are bundled and extended alongside the moving cable 6 laid between the car 1 and the machine room 7, and the other end is connected to the notification device 17. is there.

One ends of communication lines 28 and 25 are connected to the switch 12 and the buzzer 16 of the pit 3, respectively.
28 and 25 are bundled and extended in the hoistway 2, and the other end is connected to the notification device 17. In addition, the switch 9
And the buzzer 13 are connected to the notification device 17 via communication lines 26 and 23, respectively.

As shown in FIG. 2, the notification device 17 is provided with a timer 18, a control device 19, and a communication device 20, and when any of the switches is operated, the timer 18 is activated and a predetermined time is set. When the time is measured, a buzzer corresponding to the operated switch sounds. Then, the timer 18 starts counting simultaneously with the sounding of the buzzer, and if the operation of the switch is continued even after a predetermined time elapses, the control device 19 is activated and the communication device 20 is switched to the telephone line 21. The monitoring data is transmitted to the monitoring center 22 via the.

 Next, the operation of the embodiment having such a configuration will be described.

When a maintenance worker performing maintenance work on an elevator performs a maintenance work, for example, in the machine room 7, the switch 9 is turned on prior to the machine for maintenance work. By the operation of the switch 9 by the maintenance staff, the timer 18 starts counting time, and when the counting of the predetermined time set slightly shorter than the average inspection work time is completed, the buzzer 13 sounds. For this reason, the maintenance person who continues the maintenance and inspection work in a normal state notices the sound of the buzzer 13 and turns off the switch 9, so that the buzzer 13 stops the sounding, and the maintenance and inspection by the maintenance person soon thereafter. Work is completed.

If the maintenance staff loses consciousness due to a change in the body during maintenance and inspection work, the buzzer 13 will continue to ring, and for example, a passenger who is present at the top floor landing
By hearing the thirteen sounds, the building manager is notified and the manager can rescue the maintenance personnel who has lost consciousness from the machine room 7.

There is no passenger by chance near the elevator,
Alternatively, even if the sound of the buzzer 13 is not heard outside due to noise, the timer 18 starts counting at the same time as the sound of the buzzer 13 starts, and after a predetermined period of time, a timer completion signal from the timer 18 is output. Then, the control device 19 operates. This control device
By the operation of 19, abnormal data indicating that an abnormal situation has occurred to the maintenance personnel is transmitted from the communication device 20 to the monitoring center 22 via the telephone line 21. The operator of the monitoring center 22 having received the abnormal data notifies the service company of the occurrence of the abnormal situation of the maintenance staff and requests that the maintenance staff in the machine room 7 of the elevator be promptly rescued. In this way, even if the buzzer 13 is not heard, the monitoring center 22 is notified of the occurrence of the abnormal situation of the maintenance staff after a predetermined time, so that the maintenance staff can be safely rescued.
