Abstract

PURPOSE:To inform an accident to the outside during inspection of an elevator by a maintenance person by receiving a signal by a receiver in a machine room when the signal is generated from a portable wireless transmitter, and transmitting the signal and a control data of the elevator to a supervisory center by a transmitting device. CONSTITUTION:When a maintenance person 13, carrying a transmitter 7, is engaged in work in a pit 11 and hit by a cage 3, and a call button 72 is pressed immediately by the maintenance person 13 at the time of generation of an accident, an emergency is received by a receiver 8 through antennas 71, 81 and input to the CPU91 of a transmitting device 9. Next, by the CPU91 a network control unit 93 is started, and the emergency signal and a data in ROM92 are received by a receiving part 121 in a supervisory center 12 through a telephone line 101 and a telephone line network 10. Then the control number of an emergent elevator, building name, building address, etc., are displaced in a display part 123 as well as an alarm device in an alarm part 122 is sounded. As a result, the maintenance person can be rescued by immediately dispatching a watchman in the center 12 to the building.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a notification device for an elevator, and more particularly to a notification device for notifying when an unexpected accident occurs while a maintenance worker is working in a hoistway or the like.

[Conventional technology]

In elevators, maintenance personnel regularly climb on top of the cars or enter the pit of the hoistway to check whether the elevator equipment is in good working order. This inspection work is carried out by one maintenance worker, so in the event of an unexpected accident, the maintenance worker always carries an emergency bell as a means of contacting the outside world.
As disclosed in the above publication, a method has been proposed in which an intercom is provided on the top of the car or in the pit, and the intercom is used to directly communicate with the outside.

[Problem to be solved by the invention]

By the way, if an accident occurs while a maintenance worker is inspecting an elevator, with the former method, even if the emergency bell rings, passersby in the landing may not be able to tell what kind of bell it is, and rescuers may be required. Sometimes it doesn't.

In addition, in the latter method, the distance from the place where the accident occurred to the place where the intercom is installed is far,
There were times when it was not possible to use the intercom, which caused the problem of being unable to contact the outside world.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, the present invention provides a notification device that allows maintenance personnel to reliably contact the outside when an unexpected accident occurs while inspecting an elevator.

[Means to solve the problem]

The purpose of this is to provide a portable radio transmitter and a portable radio transmitter in an elevator machine room provided at the top of an elevator hoistway, and in an elevator notification device in which a car runs up and down in the hoistway. A receiver installed in the machine room receives a signal from a transmitter, and when a signal is emitted from the transmitter, the receiver receives this signal and transmits this signal and management data of this elevator. This is achieved by providing a device for transmitting data to a monitoring center via a transmission device.

[Effect]

In the event that an accident occurs in the pit etc., maintenance personnel
The maintenance personnel immediately operates the call button on the transmitter. This signal emitted from the transmitter is received by a receiver in the elevator machine room, and this signal and data such as the elevator management number are transmitted to the monitoring center via a transmission device.

As a result, the monitoring center knows that an accident has occurred, and the monitoring staff can rush to the elevator building and rescue the maintenance worker.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a block diagram of the entire system of the present invention, and FIG. 2 is a block diagram of an elevator to which this device is applied.

In Fig. 2, 1 is the hoistway, 11 is the pit of the hoistway 1, 2 is the elevator-machine room provided at the top of the hoistway 1, 3 is the car, 4 is the counterweight, 5 is the sheave, and the car 3 and the counterweight 4 is connected to the sheave 5 via the rope 6.
It runs up and down by rotating. In FIG. 1, 7 is a wireless transmitter, 71 is a transmitting antenna, and 7 is a wireless transmitter.
2 is a call button for generating an abnormal signal, 8 is a receiver for receiving the abnormal signal from the transmitter 7, and 81 is a reception antenna provided in the elevator machine room 2.

9 is a transmission device installed in the elevator machine room, and CP
Consists of U91, ROM92, network control device 93,
Management data such as elevator management number, building name, building location, etc. is stored in advance in the OM92. C
When the abnormal signal is input from the receiver 8, the PU 91 activates the network control device 93 and operates to transmit this signal and data via the telephone line 101, which will be described later. 10 is a telephone line network, and 12 is a monitoring center, which is connected by a transmission device 9, a telephone line network 1o, and a telephone line 101. The monitoring center 12 includes a receiving unit 1 that receives the abnormality signal and management data.
21, and a display section 123 that displays the received management data and the like.

Next, the operation of this embodiment will be explained.

Suppose that a maintenance worker 13 carrying a transmitter 7 hits the car 3 while working in the pit 11, and an accident occurs.

At this time, the maintenance worker 13 immediately presses the call button 72. The abnormal signal is sent to the receiver 8 via the antenna 71 and the antenna 81.
This abnormal signal is input to the CPU 91 of the transmission device 9.

The CPU 91 starts the network control device 93 and connects the telephone line 10.
1. This abnormal signal and the ROM 92 via the telephone line network 10
The data within is received by the receiving section 121 of the monitoring center 12, and the alarm of the alarm section 122 sounds and the display section 1
23 displays the management number of the elevator where the abnormality occurred, the name of the building, the location of the building, etc.

As a result, a supervisor in the monitoring center 12 can immediately rush to the building and rescue the maintenance worker.

In this embodiment, the transmission device 9 has been described as a stand-alone device, but recently some devices are equipped with a terminal device that transmits abnormal conditions of control equipment such as elevator air conditioners in buildings to a monitoring center. , this transmission device 9 can also be shared with the terminal device.

〔Effect of the invention〕

As described above, according to the present invention, if a maintenance worker has a portable transmitter, even if an accident occurs in the hoistway, the call button of the portable transmitter can be activated. By operating the , it is possible to reliably report to the monitoring center, which has the effect of quickly rescuing maintenance personnel.
