Description

[Detailed description of the invention] <Industrial application field> This invention relates to an elevator notification device.

<Prior Art> Elevators are equipped with a reporting device that allows passengers in the car to report to an elevator management organization that an abnormal situation has occurred in the elevator.

In this type of notification device that has been used conventionally, a push button is installed as an operating device inside the elevator car, and when a passenger operates the push button in the event of an abnormal situation, the elevator management organization such as the control room or monitoring center is notified. The system is configured so that the call bell is activated. In this case, when the manager or supervisor of the elevator management agency confirms that the call bell is working and picks up the alarm's handset, a call can be made between the elevator car and the elevator management agency, and the details of the abnormal situation that has occurred can be communicated. By knowing this, you can take appropriate action. The push button is configured such that when a passenger operates it, the operation is held electrically and the bell rings until the handset is picked up by a supervisor or a supervisor.

This type of elevator notification device is, for example,
It is disclosed in Japanese Patent No. 110549.

<Problems to be Solved by the Invention> As mentioned above, in the conventionally proposed elevator notification devices of this type, even if the passenger's body momentarily touches the push button and the push button is pressed, Furthermore, even if a child passenger mischievously opens the push button for a very short time, the bell will not stop ringing until the handset is taken away by the elevator management agency.

Therefore, when the elevator is crowded, erroneous operations involving passengers' bodies occur relatively frequently, which often places a mental or physical burden on the managers and supervisors of the elevator management organization.

This invention was made in view of the current state of elevator notification devices as described above, and its purpose is to prevent the operating device that activates the notification device from being momentarily operated by touching the passenger's body due to confusion during boarding and exiting. To provide a notification device for an elevator in which the continuation of the operation of the notification device is invalidated when the notification device is operated in a mischievous manner or when the elevator is operated normally.

Means for Solving Problems> In order to achieve the above-mentioned object, the present invention detects that the door of the elevator is in an open state and generates a detection signal in an elevator that operates between multiple floors. an opening detection means for detecting that the door of the elevator is in the opening/closing operation and emitting a detection signal; It is configured to include an operating device that operates the notification device provided between the notification device and a disabling means that disables the continuation of the operation of the notification device activated by the operating device in response to the detection signal.

In this invention, if the operating device is erroneously operated due to the passenger's body coming into contact with it, or if the operating device is operated by mischief, the control system between the elevator and the elevator control room, such as the control room or the monitoring center, The continued operation of the notification device installed in the vehicle is invalidated by the invalidating means. Therefore, the manager or supervisor of the elevator management organization should judge the continued operation of the notification device based on the ringing time of the bell, and communicate with the inside of the car through the notification device only when an abnormal situation occurs. I can do it.

<Example> This invention will be described in detail below based on an example using FIGS. 1 and 2.

FIGS. 1 and 2 used for detailed explanation of this invention are as follows:
FIG. 2 is a circuit diagram showing the configuration of an embodiment of the first and second inventions of this application, respectively.

First, the configuration of the first embodiment of the invention will be described using FIG.

Between the DC power terminals P and N, there are a contact 2Ba of a call button as an operating device (not shown), a contact Hb of a handset H of a notification device (not completely shown), and a bell ringing relay 1.
are connected in series, and a series connection circuit of contacts 1al and 5b is connected in parallel to contact 2Ba. Similarly, between the DC power terminals P and N, a contact Ha of the handset H and a notification device T of the notification device, which is not completely shown, are connected.
U are connected in series.

Further, a contact 1a2 and an operating bell 2A of a notification device (not completely shown) are connected in series between the DC power terminals P and N. Similarly, a contact 3a, a contact 4b, and a relay 5 are connected in series between DC power terminals P and N.

Further, a contact 3ca and a relay 3 are connected in series between the DC power terminals P and N, and in the same way, the DC power terminals P,
Contact points 41Hb to 4NHb of switches (not shown) and a relay 4, which detect the closing of the hall doors on the first to N floors, are connected in series between N and N.

In this configuration, the contact 3ca is a contact of a switch (not shown) that detects that the door of the car is closed. Further, in the above-mentioned configuration, the relay 3, the contact 3ca, the relay and the contacts 41Hb to 4NHb constitute the open detecting means, and the contact 3a, the contact 4b, the relay 5, and the contact 5b constitute the disabling means.

The operation of the embodiment of the first invention configured as described above will be explained.

When the elevator stops in the middle of the hoistway and a so-called canned food accident occurs, when a passenger presses a call button (not shown) that is an operator inside the car, contact 2Ba is turned ON.

When contact 2Ba turns ON, DC power terminal P and contact 2B
A, a contact Hb of the handset H, the bell ringing relay 1 and the DC power supply terminal N form a closed circuit, and the bell ringing relay 1 is energized.

When the bell ringing relay 1 is energized, the contact 1al is turned on, and the DC power terminal P, the contact 1a1, the contact 5b, and the contact H
b. Since a closed circuit is formed between the bell ringing relay 1 and the DC power supply terminal N, the bell ringing relay 1 is maintained even if the passenger stops operating the call button.

When the bell ringing relay 1 is energized, the contact 1a2 turns ON, and a closed circuit is formed by the DC power terminal P, the contact 1a2, the operating bell 2A, and the DC power terminal N. The operating bell 2A rings.

At the time of the canned food accident, both the car door and the landing doors on the first to N floors are closed, so the contact 3ca is OFF and the contacts 41Hb to 4NHb are ON. Therefore,
Relay 3 is in a de-energized state and relay 4 is in an energized state. For this reason, both contact 3a and contact 4b are turned OFF.
Then, relay 5 is in a de-energized state.

Since the relay 5 is in the de-energized state, the contact 5b maintains the ON state, and the bell ringing relay 1 maintains the energized state, so the operating bell 2A continues to ring. When the manager picks up the handset H in the control room, the contact Hb turns OFF, the bell ringing relay 1 is deenergized, and the contact 1a2 turns OFF.
The operating bell 2A then stops ringing. At the same time, the contact point Ha is turned on, so the manager can talk to the passengers in the car through the notification device TU, listen to the situation of the abnormal situation, and take appropriate measures.

This section describes the behavior when the elevator door is open and the elevator is boarding or exiting, and a passenger's body touches the controller due to congestion and the controller is operated, or if the controller is tampered with in this state. .

In this case, since the car door is open, contact 3ca
is ON, and at least one of the contacts 41Hb to 4NHb is OFF. For this reason, relay 3 is energized and relay 4 is deenergized, so that contact 3a is on and contact 4b is on.

Therefore, the relay 5 is in the energized state and the contact 5b is turned OFF, so the bell ringing relay 1 is not self-maintained, and when the passenger's body leaves the operating device or the mischief operation is stopped, the bell ringing relay 1 is not activated. Bell 2A stops ringing. In this case, the manager knows that the erroneous operation of the operating device is a mischief operation because the ringing duration of the operating bell 2A is short.
There is no need to pick up handset H.

In this way, the continuation of the operation of the notification device is disabled in the event of an erroneous operation or tampering with the operating device, so the manager can pick up the handset H and respond only when an abnormal situation occurs in the elevator. The mental or physical burden on people can be significantly reduced.

Next, the configuration of the second embodiment of the invention will be described using FIG.

Between the DC power terminals P and N, there are a contact 2Ba of a call button as an operating device (not shown), a contact Hb of a handset H of a notification device (not completely shown), and a bell ringing relay 1.
are connected in series, and a series connection circuit of contacts 1al and 5b is connected in parallel to contact 2Ba. Similarly, between the DC power terminals P and N, a contact Ha of the handset H and a notification device T of the notification device, which is not completely shown, are connected.
U are connected in series.

Further, a contact 1a2 and an operating bell 2A of a notification device, which is not completely shown, are connected in series to the DC power terminals P and Nf. Further, between the DC power terminals P and N, a contact 6θb of a relay (not shown) is energized when the car door is opened/closed, a contact 6cb of a relay (not shown) and a relay 5 are energized when the hall door is opened/closed. are connected in series.

In this embodiment of the second invention, the contact 6θb and the contact 6c
b constitutes an open detection means, and the relay 5 and contact 5b constitute an invalidating means.

The operation of the embodiment of the second invention described above will be explained.

When the elevator stops in the middle of the hoistway and a so-called canned food accident occurs, when a passenger presses a call button (not shown) that is an operator inside the car, contact 2Ba is turned ON.

When contact 2Ba turns ON, DC power terminal P and contact 2B
A, a contact Hb of the handset H, the bell ringing relay 1 and the DC power supply terminal N form a closed circuit, and the bell ringing relay 1 is energized.

When the bell ringing relay 1 is energized, the contact 1al is turned on, and the DC power terminal P, the contact 1a1, the contact 5b, and the contact H
b. Since a closed circuit is formed between the bell ringing relay 1 and the DC power supply terminal N, the bell ringing relay 1 is self-held even if the passenger stops operating the call button.

When the bell ringing relay 1 is energized, the contact 1a2 turns ON, and a closed circuit is formed by the DC power terminal P, the contact 1a2, the operating bell 2A, and the DC power terminal N. The operating bell 2A rings.

At the time of a canned food accident, neither the car door nor the hall door is opening or closing, so the contact 6θb or the contact 6cb will not turn OFF. Therefore, in this state, a closed circuit is formed by DC power supply terminal P, contact 6θb, contact 6cb, relay 5, and DC power supply terminal N, and since relay 5 is energized, contact 5b maintains the ON state. ing.

Therefore, unless the manager picks up the handset H installed in the management room, the bell ringing relay 1 remains energized and the operating bell 2A continues ringing. When the administrator picks up the handset H, contact Hb turns OFF.
The bell ringing relay 1 is deenergized and the activation bell 2A stops ringing.9 At the same time, the contact Ha is turned on, so the caretaker can talk to the passengers in the car through the alarm TU and listen to the situation of the abnormal situation. appropriate measures can be taken.

When the elevator door is opened or passengers are getting on and off the elevator, when a passenger touches the control device due to congestion and the control device is operated, or if the control device is tampered with in this state. Explain the operation.

In this case, when passengers finish getting on and off, the elevator door closes, and the operation is performed, contact 6θb and contact cb turn OFF.
Therefore, in order to deenergize relay 5, contact 5b is turned OFF.
F, and the bell ringing relay 1 is not self-holding. Therefore, when the passenger's body moves away from the operating device or the mischievous operation is stopped, the ringing of the operating bell 2A stops.

If the passenger's body touches the operating device while the elevator is operating,
Alternatively, if the operating device is tampered with, when the elevator arrives at the nearest stop floor and the elevator door is opened, contacts 6θb and 6cb are turned OFF, and the bell ringing relay 1 is turned off. Not self-maintained. In this case as well, the activation bell 2A stops ringing when the passenger's body moves away from the operating device or the mischievous operation is stopped.

In the second invention as well, the continuation of the operation of the notification device is disabled in the event of erroneous operation or tampering with the operating device, so the manager can pick up the handset H and respond only when an abnormal situation occurs in the elevator. This can significantly reduce the mental and physical burden on the manager.

In the embodiments of the first and second inventions, the case where the manager manages the elevators in the management room has been described, but this invention is applicable to the case where the elevators are managed at the monitoring center via a telephone line. can also be applied.

<Effects of the Invention> As explained in detail above, according to the present invention, the elevator management organization can distinguish between malfunctions and mischievous operations of the notification device.
It is possible to provide an elevator notification device that can respond efficiently only when an abnormal situation occurs in an elevator, and can significantly reduce the mental and physical burden on managers and supervisors. Become.
