JPH05338934A - In-cage announcing device for elevator - Google Patents

Abstract

PURPOSE: To eliminate a feeling of an anxiety for giving a passenger by immediately announcing passengers in a cage during informing through an interphone when confinement of the passengers in the cage is judged by a monitoring means upon pressing of an emergency call button. CONSTITUTION: When a service of an elevator is fault and an emergency call button 2b is pressed exceeding a predetermined time in a cage 1b, a master unit 7 judges that the passengers in the cage 1b is confined. Then, to rescue the passengers from the unit 7, an information to a monitor sensor is instructed to a modem 8. When a switch SW1 is switched to a voice synthesizing means 11 side by the unit 7, a switch Sl2 of the cage 1b side is closed, and simultaneously the means 11 is started. Thus, 'communicating at present to an operator in charge' is, for example, informed through an interphone 3b in the cage 1b. 'Please wait as you stay in the cage as it is' is announced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-car announcement device for an elevator, which informs a passenger that a passenger is trapped in a car due to a poor elevator operation. ..

[0002]

2. Description of the Related Art An elevator car is provided with an emergency call button for making a call from the inside of the car to a monitoring center for external maintenance and inspection, and an intercom that allows direct calls from inside the car to the monitoring center. Has been. If a passenger is trapped in the car due to a malfunction in the elevator, the passenger will press the emergency call button and the intercom will call the surveillance center for help. The surveillance center will then immediately dispatch maintenance personnel to rescue the trapped passengers.

[0003]

As described above, in the conventional elevator, when passengers are trapped in the car, it takes about a period of time to press the emergency call button and reach the outside monitoring center from the intercom. It takes about a minute. This time of about one minute is very long for passengers trapped in the car, and there is a problem that they feel anxious before contacting them.

An object of the present invention is to provide an in-car announcement device for an elevator, which informs the passenger that he / she is being notified immediately when the passenger is trapped in the car, and removes anxiety.

[0005]

In order to achieve such an object, according to the present invention, an elevator control panel for controlling the operation of an elevator car and a signal from the elevator control panel are used. A monitoring means for monitoring whether the car is operating normally, an emergency call button provided inside the car for making a call outside the car, an intercom installed inside the car for making a call outside the car, and the emergency call mentioned above. When the monitoring means determines that the passenger is trapped in the car by pressing the call button, the intercom immediately announces to the passenger in the car that the call is being made. It is a thing.

[0006]

When the monitoring means determines that the passenger is trapped in the car by pressing the emergency call button, the voice synthesizer immediately announces to the passenger in the car that the intercom is making a call.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 and 2 are views showing an embodiment of an in-car announcement device for an elevator according to the present invention.

In FIG. 1, emergency call buttons 2a and 2b for calling outside to the outside of the cars 1a and 1b of a plurality of elevators installed in a building, etc., and an intercom for directly calling outside from inside the car 3a, 3b
Etc. are provided. Elevator control boards 4a and 4b are provided on the plurality of cars 1a and 1b, respectively.
1b is in service.

The elevator control boards 4a, 4b are constantly monitored by the monitoring means 5 for the normal operation of the elevator cars 1a, 1b. The monitoring means 5 is a slave unit 6a, 6b, a master unit 7, a modem. It consists of 8 mag.

The slave units 6a and 6b have a serial converter, and have elevator control power output from the elevator control panel, safety circuit, door circuit, door open, running, call generation, maintenance, zoning, dedicated operation, Signals such as the standard floor and landing accuracy are input, and the signals are converted into parallel data and converted into serial data. Also,
Emergency call button 2 on each slave unit 6a, 6b
a, 2b signals are input, and intercoms 3a, 3
Switch S for direct communication with the outside by b
l ₁ and Sl ₂ are provided.

Serial data is transferred from each slave unit 6a, 6b to the master unit 7. The master unit 7 has a CPU, a memory, a serial converter, and the like, processes serial data output from the slave units 6a and 6b, and grasps the state of each elevator by a unique failure detection method. Also,
A switch Sw is provided between the master unit 7 and the modem 8.
₁ is provided.

In order to transmit the digital signal from the master unit 7 to the monitoring computer 9 installed in the external monitoring center, the existing analog signal telephone line 1 is used.
3 is used, the digital signal is once digital-to-analog converted by the modem 8 and transmitted from the telephone line 13, and again the analog-to-digital conversion is made by the center modem 10 to be converted into a digital signal by the monitoring computer 9
Are typing in.

The monitoring computer 9 periodically sends the processing result of the serial data transmitted from the master unit 7, analyzes and saves the processing result. Further, on the screen of the monitoring computer 9, it is possible to display and monitor the state of each input signal of an arbitrary elevator, running, stopped, open / close state of the door, etc. in real time.

A voice synthesizing means 11 having a switch Sw ₂ is provided between the switches Sl ₁ and Sl _{2 of} each slave unit 6a and 6b and the modem 8, and the voice synthesizing means 1 is provided.
Reference numeral 1 comprises a ROM, a D / A converter, an amplifier and the like.
The voice data announced in the car (for example, "I am in contact with the staff. Please wait.") Is digitally recorded in the ROM, converted into an analog voice signal by the D / A converter, and this is amplified. The signal is amplified by and is output from the speakers in the intercoms 3a and 3b.

Here, the master unit 7 is a modem 8,
Switches Sl ₁ , Sl ₂ , Sw ₁ , Sw ₂ , voice synthesizing means 1
1st grade is controlled.

Next, the operation of this apparatus will be described with reference to the flow chart shown in FIG.

When the elevator is not operating properly and the emergency call button 2 has been pressed for more than the predetermined time, it is judged by the master unit 7 that passengers are trapped in the car 1b, for example (step S). ₁ ). Next, the master unit 7 instructs the modem 8 to report to the monitoring center to rescue passengers (step S ₂ ).

Next, the switch Sw ₂ is switched to the voice synthesizing means 11
To the side (shown by the solid line) (step S ₃ ). Next, put the switch Sl ₂ of cage 1b side are trapped passenger now (step S _4). Next, the voice synthesis means 11
It was started, the car 1b in, for example, to "just now, is in contact to the staff. Please wait." And to announce (step S _5).

Next, the master unit 7 determines whether or not it is in a state where it is possible to directly talk with the monitoring center via the telephone line 13 (step S ₆ ). Next, when communicating with the monitoring center, the switches Sw ₁ , S
w ₂ is switched to the intercom 3b side (indicated by the alternate long and short dash line) (step S ₇ ). Then, the handset 12 of the monitoring center and the intercom 3b in the car 1b are connected, and the passenger in the car 1b can call the maintenance / inspector directly to ask for rescue.

In this way, when the passenger presses the emergency call button 2b, the intercom 3b calls for a rescue at the monitoring center, but within about 1 minute until then, the voice synthesizing means 11 immediately reports to the car 1b. It announces that it is inside.

[0021]

As described above, according to the present invention,
When the monitoring means determines that the passenger has been trapped in the car due to the emergency call button being pressed, the voice synthesizer immediately announces to the passengers in the car that the intercom is making a call. Passengers will no longer be anxious until they are contacted, and they can wait for rescue with peace of mind.
