Abstract

PURPOSE:To safely and rapidly rescue a maintenance man even if an abnormal situation occurs on the maintenance man under working by providing a switch operated prior to maintenance and inspection work, operating an alarm device when a determined time has passed from the operation of the switch, and sending the information to an emergency communication center. CONSTITUTION:A maintenance man conducts ON operation of a switch 9 prior to the start of maintenance and inspection work. When the time counting of a determined time by a timer 18 is completed, a buzzer 13 is sounded. The maintenance man continuing the maintenance and inspection work in normal state notices the sound of the buzzer 13 and conducts OFF operation of the switch 9. As the buzzer 12 continues to sound if the maintenance man loses his sense, a user notices the sound of the buzzer 13 and notifies the manager of a building of this. The timer 18 starts counting together with the start of sounding of the buzzer 13, and after a determined time, a control unit 19 is operated by the counting completion signal from the timer 18. By this operation, an abnormality data showing the occurrence of an abnormal state on the maintenance man is transmitted from a communication device 20 to a monitor center 22 through a telephone circuit 21.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] 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 situation that has occurred.

[Conventional technology]

If an accident occurs in an elevator, it not only causes inconvenience to the elevator users, but also may lead to personal injury. Maintenance and inspection work is being carried out by maintenance personnel. A maintenance worker who performs this maintenance and inspection work is dispatched by a service company that manages the elevator, and travels around the area in charge of the maintenance and inspection work.

Except for special work, this maintenance and inspection work is usually performed manually by people in the machine room, in the pit, in or on the car. Therefore, if an abnormal situation occurs in which a maintenance worker becomes physically unwell and unable to carry out maintenance and inspection work, the abnormal situation will occur unless the maintenance worker himself/herself reports to the outside. If it is not clear, there is a risk that maintenance staff will be trapped at the site performing maintenance and inspection work for a long time.

Therefore, each maintenance worker who performs maintenance and inspection work carries a crime prevention buzzer, and when an abnormal situation occurs, the maintenance worker operates this crime prevention buzzer and uses the buzzer's alarm sound to alert them to the occurrence of an abnormal situation. Reports are being made externally.

[Problem to be solved by the invention]

When maintenance personnel are in the machine room, notifications using conventional crime prevention buzzers are often too noisy to reach the outside. It is also known that even when maintenance personnel are on the car or in the pit, it is difficult to hear this notification sound from outside if the area around the landing area is noisy. Furthermore, if maintenance personnel are unable to operate the security buzzer they carry and suddenly lose consciousness, they are unable to notify anyone outside.

The present invention has been made in view of the current state of emergency reporting of abnormal situations caused by maintenance personnel to external parties, as described above, and its purpose is to ensure that abnormal situations occurring to maintenance personnel during maintenance inspection work are reported to external parties. An object of the present invention is to provide an emergency call device that can make a call.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a switch operated by a maintenance worker who performs maintenance work on an elevator, an alarm for reporting, and a device that activates the alarm when the switch is operated for a predetermined period of time. If the switch remains in operation even after a predetermined period of time has elapsed since the alarm was activated, the alarm system is configured to include a reporting device that transmits abnormality data to an emergency dispatch center via a telephone line.

[Effect]

With this configuration, maintenance personnel operate the switch before starting maintenance work. If this switch continues to be operated for a predetermined period of time (for example, a period slightly shorter than the average maintenance/inspection work time), the alarm is activated by a timer completion signal. By activating this alarm, maintenance personnel must remember to release the switch operation.

If a maintenance worker becomes physically ill and collapses during maintenance and inspection work, the notification device will detect that the switch is still being operated after a predetermined period of time after the alarm is activated, and the notification device will detect that the switch is still being operated. via telephone line to the emergency contact center (
For example, the abnormality data is sent to a monitoring center).

In this way, the occurrence of an abnormal situation that occurs to maintenance personnel during maintenance and inspection work is reliably reported to the emergency contact center.

〔Example〕

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

FIG. 1 and FIG. 2 are diagrams for explaining an embodiment, with FIG. 1 being an explanatory diagram showing the overall configuration, and FIG. 2 being a block diagram showing the configuration of main parts.

In FIG. 1, 2 is a hoistway, and a car 1 is disposed in the hoistway 2 so that it can be raised and lowered freely.
A shock absorber 4 is attached to this pit 3. In this embodiment, a buzzer is used as an alarm, and a driving panel 5 is provided inside the basket 1, and a switch 11 and a buzzer 15 are arranged at the bottom of the driving panel 5. Gago 1
A switch 10 and a corresponding buzzer 14 are attached to the top, and a switch 12 and a corresponding buzzer 1 are attached to the pit 3.
6 is the installation.

A machine room 7 is provided at the upper end of the hoistway 2, and a control panel 8 equipped with a notification device 17 is arranged in the machine room 7. Further, a switch 9 and a corresponding buzzer 13 are installed in the machine room 7, and a notification device 17 in the machine room 7 is connected to a monitoring center 2, which is an emergency contact center, via a telephone circuit 21.
Connected to 2.

The switch 11 and the buzzer 15 are connected to one ends of communication lines 29 and 30, respectively, and the switch 10 and the buzzer 14 are connected to one ends of communication lines 24 and 27, respectively. These communication lines 24, 27, 29, 30 are bundled and extended in line with the moving cable 6 stretched between the cage 1 and the machine room 7, and the other end is connected to the notification device 17. It is.

One end of a communication line 28.25 is connected to the switch 12 and the buzzer 16 of the pit 3, respectively, and these communication lines 28.25 are bundled and extended into the hoistway 2, and the other end is is connected to the notification device 17. Further, the switch 9 and the buzzer 13 are connected to the communication line 26.
It is connected to the notification device 17 via 23.

As shown in FIG. 2, the notification device 17 is provided with a timer 18, a control device 19, and a communication device 20. When any switch is operated, the timer 18 starts and a preset time elapses. When the time is counted, the buzzer corresponding to the operated switch will sound. The timer 18 starts timing at the same time as the buzzer sounds, and if the switch continues to be operated even after a preset period of time has elapsed, the control device 19 is activated to connect the communication device 20 to the telephone line 21. It is configured such that abnormality data indicating the occurrence of an abnormal situation of a maintenance worker is transmitted to the monitoring center 22 via the monitoring center 22.

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

When a maintenance worker who performs maintenance and inspection work on an elevator performs maintenance and inspection work in the machine room 7, for example, he turns on the switch 9 before starting the maintenance and inspection work. The timer 18 starts measuring time by operating the switch 9 by the maintenance personnel, and when the timer 18 has finished measuring a predetermined time set slightly shorter than the average inspection work time, the buzzer 13 sounds.

Therefore, maintenance personnel who are continuing maintenance and inspection work under normal conditions may notice the sound of the buzzer 13 and turn the switch 9 OFF.
Since the operator F is operated, the buzzer 13 stops sounding, and after that, the maintenance and inspection work by the maintenance personnel is completed.

If a maintenance worker loses consciousness due to physical discomfort during maintenance inspection work, the buzzer 13 will continue to sound, so if, for example, a passenger present at the top floor landing hears the sound of the buzzer 13, the buzzer 13 will continue to sound. Hearing this, the building manager is alerted, and the manager is able to rescue the unconscious maintenance worker from machine room 7.

Even if there are no passengers near the elevator or the sound of the buzzer 13 cannot be heard from outside due to noise, the timer 18 starts counting as soon as the buzzer 13 starts sounding, and the timer 18 starts counting for a preset period of time. Afterwards, the control device 19 is activated by a timing completion signal from the timer 18. As a result of the operation of the control device 19, abnormal data indicating that an abnormal situation has occurred to the maintenance staff is transmitted from the communication device 20 to the monitoring center 22 via the telephone line 21. The operator reports the occurrence of the maintenance worker's abnormal situation to the service company and requests that the maintenance worker in the elevator machine room 7 be immediately rescued. In this way, even if the sound of the buzzer 13 cannot be heard, the monitoring center 22 will receive a notification of the maintenance worker's abnormal situation after a predetermined period of time, so the maintenance worker can be safely rescued.

As mentioned above, not only when maintenance personnel perform maintenance and inspection work in machine room 7, but also when maintenance personnel require fraud inside bit 3, car 1, or on car 1, switch 1 is pressed before maintenance and inspection work.
2. By turning on switch 11 or switch 10, exactly the same operation is performed.

In this way, according to the embodiment, even if a maintenance worker who is performing maintenance inspection work experiences a physical disorder and falls down, the switch 9, 10, 11, 12 is turned off within a predetermined time.
Since it is detected that F is not operated and abnormal data is sent to the monitoring center 22, the maintenance worker can be safely rescued.

In addition, in the example, a case was explained in which switches were provided in four locations: in the machine room, on the car, inside the car, and in the bit, but the present invention is not limited to the example, and for example, the installation inside the car may be omitted. It may be installed in three locations. Further, in the embodiment, a case where a reporting device is provided separately has been described, but it can also be installed using an existing building remote monitoring device. moreover,
In the example, the buzzer is installed in the machine room, on the car, inside the car, and inside the bit, and the notification destination is the monitoring center. However, if the buzzer is installed in the building management room, the notification destination is the service company and the switch The switch may be centrally provided in the machine room, and maintenance personnel may turn on the switch in the machine room before maintenance and inspection work.

〔Effect of the invention〕

As explained in detail above, the present invention includes a switch that is operated prior to maintenance and inspection work, and when a predetermined time has elapsed since the switch is operated, an alarm is activated and a notification is sent to an emergency contact center. This prevents maintenance personnel performing maintenance and inspection work from forgetting to return the switch, and even if an abnormal situation occurs to the maintenance personnel during maintenance work, it is possible to rescue the maintenance personnel safely and quickly.
