Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reporting device for making calls from inside an elevator car to the outside.

As a communication device between the inside of the elevator car and the outside, lines are installed between the inside of the elevator car and the manager's room, and between the inside of the car and the external management company.
Japanese Patent Application No. 50-92583 (later published in Japanese Unexamined Patent Publication No. 52-1983) proposed that line switching be performed manually by the administrator.
16755)).

However, since the switching of the line is done manually, there is a risk of forgetting to switch the line, which causes problems in reporting when the manager is absent, and has the disadvantage that the function of the reporting device cannot be fully utilized. The present invention improves the above-mentioned drawbacks, and its purpose is to ensure communication between inside the car and the outside, and also to notify the location of the elevator when a passenger inside the car and an external management company make a call. An object of the present invention is to provide an elevator notification device that enables the following.

If an elevator breaks down with passengers inside the car, the passengers will be trapped inside the car.

At this time, the passenger uses the reporting means installed inside the car to contact the outside and request rescue. Therefore, it must be a reporting device that can be reliably connected to the outside. A feature of the present invention is that an auto-dial unit and a device that announces information regarding the location of the elevator are provided, and if there is no response from a supervisor etc. to a call from a communication device in the car, the auto-dial The unit automatically connects to an external management company, informs them of the elevator's location, and allows them to communicate directly from inside the car.

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a system diagram showing an example of an elevator notification device currently under development.

1 is an elevator car, 2 is a telephone receiver, and 3 is a transmitter.

Reference numeral 4 denotes an activation switch which operates the manager's room communication telephone device 10 and the timer unit 14 via the "Present-Absent" switch T if the "Present-Absent" switch is on.
When the presence-absence switch is absent, the switch circuits 13 and 22 and the auto-dial unit 20 are operated via the gate circuit 21.

5 and 6 are amplifiers, 8 and 9 are connection lines, 11 is a handset for communication with the inside of the elevator car, and 12 is a connection line for communication.

Reference numeral 15 denotes a hybrid circuit that separates transmitted and received signals, and connects the 2-wire audio line and the 4-wire audio line.

19 is a response circuit that detects that the external management company has responded.

Reference numeral 23 designates a central office line monitoring circuit for monitoring whether the central office line is blocked by incoming or outgoing calls, 24 a disconnector from the central office line, 25 a demarcation point from the central office line, and 26 the telephone set.

If the elevator breaks down, a passenger in the car operates switch 4 to contact the person, and if the manager is present, the "not present" switch 7 installed in the manager's room will switch to the occupied side. Therefore, the communication telephone device 10 for the manager's room is connected to the telephone connection line 12 and the switch circuit 1 via the connection line 8.
3. Since it is connected to the receiver 2 and the transmitter 3 via amplifiers 5 and 6, it is possible to communicate with passengers in the elevator car. Next, when the administrator is absent, the general rule is to operate the ``Present Absence 1'' switch to the absent side.
Even if the user forgets to perform the above operations, the timer unit 14 is activated via the connection line 9 by repeatedly operating the switch 4. Therefore, if there is no response from the manager or the like within a certain period of time, the timer unit 14 operates, and its output signal activates the switch circuits 13, 22 and the auto-dial unit 20 via the gate circuit 21. The auto-dial unit captures the telephone line of the station and then automatically sends out a dialing signal. The switch circuit 13 connects the hybrid circuit to the amplifiers 5 and 6 and disconnects the manager's room communication telephone device 10. The switch circuit 22 is a divider 24
The auto dial unit 20 is connected to the terminal K1 of the terminal K1, and the office line monitoring circuit 23 is disconnected. After the dial signal is automatically sent, the response detection circuit 19 detects that the external management company has responded by using the polarity reversal of the caller's telephone line. Since the detection circuit 19 is AC-connected to the hybrid circuit, passengers in the elevator car can communicate directly with the external management company. When the timer unit 14 operates, if the office line is blocked by an incoming or outgoing call, the office line monitoring circuit 23 operates and blocks the gate circuit 21, so that the office line becomes open. At that point, the station line is captured and the call is made. Therefore, this telephone can usually be used as a standalone telephone. 1 present, 1 absent. If the switch is operated to the absent side, the timer unit 14
Therefore, by operating the switch 4 installed in the car, an immediate station line acquisition operation is performed.

K1 and K2 of the disconnector 24 operate in conjunction with each other, and by operating the disconnector, the elevator emergency reporting device is disconnected from the telephone line of the station, and the telephone is directly connected to the telephone line of the station.

In this way, according to the system under development, if there is no response from the manager, an external management company is called, so passengers inside the car can reliably communicate with the outside.

However, unlike a manager, an external management company manages a large number of elevators, so it is necessary to know their whereabouts through interaction with passengers, which may cause confusion for inexperienced passengers. . FIG. 2 is a system diagram showing an embodiment of the elevator emergency notification device according to the present invention.

The same parts as in FIG. 1 are indicated by the same symbols.

The present invention adds an automatic announcement device to the above-described configuration.

This will be explained in detail below. An automatic announcement device 16 notifies an external management company of the location of the elevator, and includes a motor 161 and a magnetic tape 162.

17 is a signal connection line, and 18 is a control connection line.

The response detection circuit 19, which uses polarity reversal to detect that the external management company has responded by the above-described operation, detects a response via the control connection line 18 before the passenger in the car interacts with the external management company. controls the automatic announcement device 16, and sends announcements such as the name and address of the building to which the elevator belongs to an external management company via the signal connection line 17. The detection circuit 19 is AC-connected to the hybrid circuit 15, so that after hearing the announcement, the external management company can directly communicate with the passengers in the car. In this way, this embodiment is configured to automatically switch between the call line in the car, the manager's room, etc., and the call line to the external management company.

Therefore, even if someone forgets to operate the "Are you absent" switch installed in the manager's room, etc., the external management company can be contacted reliably, reducing the mental and physical burden on the manager. can. In addition, since the inside of the car and the external management company can communicate directly, appropriate instructions and communication can be given. Of course, the same effect can be expected if the above-mentioned "absence" switch is not provided, and the manager's office is called for a predetermined period of time, and after the predetermined period of time, the line is automatically switched to the external management company. . As explained above, according to the present invention, it is possible to reliably make a call between the inside of the car and the outside, and when making a call with an external management company, the minimum necessary information for the management company is transmitted. Since the information can be heard automatically, even inexperienced passengers can respond quickly, reducing their anxiety.
