Abstract

PURPOSE:To surely and quickly rescue the workers in a building who are wounded by an accident and unable to move themselves by notifying the worker identification codes and the building code to a monitor center by means of an emergency notifying means. CONSTITUTION:When an elevator is checked, a worker 14 first inputs his identification code, the scheduled worke time and the check start input via an input device 11. These input items are set to a terminal controller 9 which puts a communication equipment 10 in a communication preventing state. Then the worker 14 performs his work and the scheduled working time is subtracted. If an end input operation is carried out and the worke time extension input operation is not carried out neither before the scheduled worke time ends, the count value of an input wait timer is subtracted. If both end input and worke time extension input operations are not carried out before the input wait timer counts up its limit time, a worker's abnormality report is outputted from the controller 9 in such a case where the worker 14 falls to the bottom part of a lift path of a cage 1 and cannot move by himself. Thus this accident is notified to a monitor center 12 via the equipment 10 and a telephone circuit 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring device for building equipment, and more particularly to a remote monitoring device for building equipment suitable for notifying an unexpected accident of a worker during work.

[0002]

2. Description of the Related Art In an elevator, which is one of building facilities, workers regularly check whether elevator equipment is normal by riding on a car or entering a hoistway pit. . Since this inspection work is performed by one worker, a portable call button, a microphone and a speaker described in JP-A-2-295869 are provided as means for contacting the outside in the event of an unexpected accident. A means for connecting a wireless communication device and a repeater for transmitting and receiving signals of the wireless communication device in the elevator machine room, and connecting the call button, microphone and speaker terminal of the repeater and the communication device in the elevator machine room in parallel, respectively. An emergency call device for an elevator equipped with was proposed.

[0003]

In the above-mentioned prior art, the worker communicates with the outside by the wireless communication device carried by the worker. However, when the wireless communication device is placed in another place, an accident occurs. There was a problem that when the incident occurred, or in the case of an accident in which the operator could not operate even when carrying the wireless telephone, he could not contact the outside.

An object of the present invention is to provide a remote monitoring apparatus for building equipment, which enables an operator to contact the outside without any operation when an accident occurs while working on building equipment. Especially.

[0005]

In order to achieve the above object, the present invention is directed to a terminal device for detecting and reporting an abnormality of equipment installed in a building, which is connected to the terminal device via a communication line. In a remote monitoring device for building equipment, which comprises a monitoring center that processes information transmitted from the terminal device and remotely monitors the occurrence of abnormalities in the equipment, a worker who performs work on the equipment is Notification for identifying the worker identification code, the correctable scheduled work time required for the work, and the work start operation for identifying that the work is in progress, which is activated when the abnormal notification of the terminal device is prevented. When the blocking means and the report blocking means are activated, the operation for ending the work for canceling the report blocking means is not input by the time counting and inputting the scheduled work time. Can, in which the building identification code that identifies the building in which the operator identification code and work is being carried out and a very report means for reporting to the monitoring center.

[0006]

With this structure, the terminal device causes an accidental accident to the worker when the scheduled work time input in advance is not extended or the work end operation is not performed. Therefore, the worker identification code and the building code are notified to the monitoring center by the emergency notification means.
Even if a large accident occurs in which the worker cannot move, the worker can be rescued reliably and promptly.

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, in an elevator which is one of building facilities, a car 1 and a counterweight 2 are connected by a rope 4 via a sheave 3A and a deflector wheel 3B, and the sheave 3A rotates to cause reciprocal movement in a hoistway 5. Move up and down.
Further, the car 1 and the elevator control device 6 are connected by a cable 7, and the abnormality detection device 8 is connected to the elevator control device 6, and constantly monitors a plurality of predetermined signals of the elevator control device 6 to detect a logical failure or The occurrence of an abnormality is detected, and the communication device 10 is connected via the control device 9 of the connected terminal device.
Outputs an error occurrence signal. An input device 11 such as a keyboard or a numeric keypad is connected to the control device 9 of the terminal device. When the communication device 10 receives an abnormality occurrence signal from the control device 9 of the terminal device, the communication device 10 automatically dials the communication device 12A of the monitoring center 12 and outputs the abnormality occurrence signal to the monitoring center 12 via the telephone line 13.

Further, the communication device 12A is a monitoring center control device 12B for controlling the monitoring equipment of the monitoring center 12.
And the telephone 12C, and the monitoring center controller 12B
Are connected to a storage device 12D, a display device 12E, and an input device 12F such as a keyboard.

Next, the operation will be described.

When the worker 14 inspects the elevator, the worker 14 first inputs the worker identification code, the scheduled work time, and the inspection start input through the input device 11 (step S1). It is set for the terminal control device 9, and the terminal control device 9 puts the communication device 10 into the communication blocking state (step S2). The worker 14 performs the work, the scheduled work time is subtracted (procedure S3), the end input (procedure S5) is not input, and the work time extension input (procedure S6) is not performed before the scheduled work time runs out (procedure S4). In this case, the input waiting timer is decremented (step S7). If the end input (procedure S5) is not made before the waiting timer expires (procedure S8) and the work extension input (procedure S6) is not performed, for example, the worker 14 moves from the car 1 to the bottom of the hoistway 5. When the worker falls and cannot move, a worker abnormality alarm is output from the terminal control device 9 and is notified to the monitoring center 12 via the communication device 10 and the telephone line 13 (step S9).

Next, in step S6, if the worker 14 inputs a work extension with the input device 11, the operations in step S3 and thereafter are repeated.

Next, in step S5, when the worker 14 finishes input through the input device 11, the communication device 10 is released from the communication blocking state (step S10), and enters the normal monitoring state.

[0014]

According to the present invention, when the terminal device does not extend the scheduled work time or finish the work even when the scheduled work time is input in advance, it is determined that an unexpected accident has occurred in the worker. Since the worker identification code and the building code are notified to the monitoring center by the emergency notification means, the worker can be rescued surely and promptly even if a large accident occurs in which the worker cannot move.
