Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention relates to an elevator notification device, and in particular to an elevator in which a monitoring interphone is called by operating a hall call button on a floor set as a non-stop floor or an interphone call button in the car. The present invention relates to a notification device.

0002

[Prior Art] In elevators, for example, a so-called canned food accident, in which a passenger is trapped in a car, may occur due to a power outage. If a floor with no access to other floors is set as a non-stop floor, an accident may occur in which passengers are trapped in the landing on that floor.

[0003] In order to deal with the occurrence of such accidents,
In Utility Model Application Publication No. 58-23867, an elevator system in which a monitoring intercom installed in the control room of the building where the elevator is installed is called by operating a call button at a landing on a floor set as a non-stop floor. A notification device is disclosed.

0004

[Problems to be Solved by the Invention] In the above-mentioned conventional notification device, a passenger who is trapped in a landing on a floor that is set as a non-stop floor and has no access route to another floor, When the call button is operated, the intercom for monitoring the control room is called. However, the monitoring intercom can also be called using the intercom call button installed inside the elevator car, so the monitoring intercom's ringing sound alone cannot be used.
The manager cannot determine whether the intercom was called from inside the car or from a landing on a non-stop floor. Further, even if a passenger in the car operates the intercom call button, the passenger may be unable to respond to the manager's question because, for example, the passenger has a hearing impairment. For this reason, the manager who hears the ringing sound of the monitoring intercom may be confused as to whether the passenger is trapped in the car or in a landing on a non-stop floor. In some cases, the rescue of trapped passengers was delayed due to inadequate response measures.

The present invention was made in view of the current state of elevator notification devices as described above, and its purpose is to detect whether a passenger is trapped in a car or not by the ringing sound of a monitoring intercom. To provide an elevator notification device that can easily determine whether a person is trapped in a landing on a non-stop floor.

[0006]

[Means for Solving the Problems] The object is to provide a call button installed in an elevator equipped with a non-stop floor setting means for setting a non-stop floor, a call button provided in a landing, and an intercom call button provided in a car. , an elevator notification device that is provided at a monitoring position of the elevator and includes an elevator monitoring interphone that is called by operating the call button of a floor set as a non-stop floor or the interphone call button, This is achieved by adopting a configuration including a ring tone generating means that causes the interphone to generate different ring tones depending on the operation of the interphone call button and the operation of the interphone call button.

[0007]

[Operation] With this structure, the ring tone generating means is activated when the monitoring intercom is called, and when the passenger operates the intercom call button in the car, and when the intercom is set to a non-stop floor. When operating the call button of the landing on a different floor, different ring tones are generated from the intercom. Therefore, it is possible to determine from where the customer made the emergency call just by hearing the ringing tone of the elevator monitoring intercom.

Embodiment An embodiment of the present invention will be described below with reference to FIG. Here, FIG. 1 is a circuit diagram showing the configuration of an embodiment. For the sake of simplicity, FIG. 1 shows only the circuit parts necessary for explaining the case where the second floor is set as a non-stop floor.

As shown in FIG. 1, a non-stop floor setting switch SW and a non-stop floor setting relay NA are connected between DC power supply terminals P and N.
are connected in series with each other, and similarly, between the DC power terminals P and N, the call button 2U for the ascending direction of the second floor landing, the normally open contact NA1a of the non-stop floor setting relay NA, and the ascending relay 2 are connected to each other in series.
The HUs are connected in series with each other. A normally closed contact N of the non-stop floor setting relay NA is connected between the connection point of the upward direction nominal button 2U and the normally open contact NA1a and the DC power supply terminal N.
A1b and non-stop floor call relay NST are connected in series.

Further, a call button 2D for the descending direction of the second floor landing, a normally open contact NA2a of the non-stop floor setting relay NA, and a descending relay 2HD are connected in series between the DC power terminals P and N. Between the connection point of button 2D and normally open contact NA2a and the connection point of normally closed contact NA1b and nonstop floor call relay NST, normally closed contact NA2b of nonstop floor setting relay NA is connected.
is connected. The normally open contact NST1 of the non-stop floor call relay NST and the landing position display lamp LP of the non-stop floor placed in the landing indicator are connected in series between the DC power terminals P and N. Similarly, a monitoring interphone INT is connected between DC power supply terminals P and N.

[0011] This interphone INT includes a first ring tone generating circuit T1 which is activated by operating an interphone call button CALL provided in the car, and a non-stop floor call relay N.
A second ringing tone generating circuit T2 is provided which is activated when the up direction call button 2U or the down direction call button 2D is operated when ST is energized. The interphone is configured to generate different ring tones when the first ring tone generation circuit T1 is activated and when the second ring tone generation circuit T2 is activated.

In an embodiment with such a configuration, a non-stop floor setting switch SW, a non-stop floor setting relay NA, normally open contacts NA1a, NA2a, and normally closed contacts NA1b, NA2b
constitutes the non-stop floor setting means of the invention, and the first ringing tone generating circuit T1 and the second ringing tone generating circuit T2 constitute the ringing tone generating means of the invention.

Next, the operation of the embodiment having such a configuration will be explained.

When the second floor is not set as a non-stop floor, the non-stop floor setting switch SW is switched to the terminal b side, so the non-stop floor setting relay NA is energized and the normally open contacts NA1a, NA2a is closed, normally closed contacts NA1b, N
A2b is open. In this state, when a passenger operates the call button 2U in the ascending direction at the landing on the second floor, the DC power terminal P, the call button 2U, the normally open contact NA1a, and the ascending relay 2H
A closed circuit is formed between U and the DC power supply terminal N, and the ascending relay 2HU is energized, so that the elevator stops at the second floor in response to the call for the second floor and then ascends. Similarly, when a passenger operates the call button 2D in the descending direction at the landing on the second floor, the DC power terminal P, call button 2D, normally open contact NA
2a, a closed circuit is formed by the descending relay 2HD and the DC power terminal N, and the descending relay 2HD is energized, so that the elevator stops at the second floor in response to a call for the second floor and then moves downward.

By the way, in order to set the second floor as a non-stop floor, when the non-stop floor setting switch SW is switched to the terminal a side, the non-stop floor setting relay NA is deenergized, so the normally open contact NA
1a and NA2a are opened, and normally closed contacts NA1b and NA2b are closed. In this state, even if a passenger operates the call button 2U in the ascending direction on the second floor landing, the ascending relay 2HU will not be energized, but the DC power terminal P, the call button 2U, the normally closed contact NA1b,
A closed circuit is formed by the non-stop floor call relay NST and the DC power supply terminal N, and the non-stop floor call relay NST is energized.

In this way, the non-stop floor call relay NS
When T is energized, the normally open contact NST1 is closed and the hall position display lamp LP of the non-stop floor provided in the hall indicator lights up. In addition, the normally open contact NST2 is closed by energizing the non-stop floor call relay NST, so the second ring tone generation circuit T2 is activated and is installed in the control room of the building where the elevator is installed. Monitoring intercom IN
T rings on a second ring.

In this case, even if the passenger operates the call button 2D in the descending direction at the landing on the second floor, the descending relay 2HD is not energized, but the DC power terminal P, the call button 2D, the normally closed contact NA2b,
A closed circuit is formed by the non-stop floor call relay NST and the DC power supply terminal N, and the non-stop floor call relay NST is energized. Therefore, in the same way as when the call button 2U in the upward direction is operated, the landing position display lamp LP for the non-stop floor lights up.
In addition, the second ringing tone generation circuit T2 is activated, and the monitoring interphone INT rings with the second ringing tone. On the other hand, when a passenger in the car operates the intercom call button, the normally open contact CALL is closed, the first ring tone generating circuit T1 is activated, and the monitoring interphone INT is switched to the second ring tone generating circuit T1. A first ring tone having a different frequency from the ring tone sounds.

As described above, according to the embodiment, the manager of the building where the elevator is installed can hear the ringing sound of the monitoring intercom INT installed in the control room, and the manager can hear the calls from the passengers in the elevator car. It is possible to accurately and quickly determine whether the call is from a passenger who is trapped in a landing on a floor set as a non-stop floor, and the system can quickly take optimal measures in the event of a trapping accident. It becomes possible to rescue the customer. Furthermore, in the embodiment, even if a passenger in the car has a hearing impairment and is unable to talk to the caretaker via the intercom INT, the caretaker who receives the call will be able to confirm that the call is correct. It is possible to know from the customers inside what has been done due to the occurrence of an emergency situation, and to deal with it appropriately and quickly.

[0019] In the embodiment, a case where the second floor is set as a non-stop floor has been explained, but the present invention is not limited to the embodiment, and it is also possible to set floors other than the entrance/exit floor as a non-stop floor. can. Further, in the embodiment, a case has been described in which the first ring tone and the second ring tone have different frequencies, but this is not limited to the embodiment, and for example, continuous ring tone and intermittent ring tone may be distinguished. is also possible.

[0020]

Effects of the Invention As described above in detail, in the present invention, the operation of the intercom call button for monitoring is performed by operating the call button at the landing of the floor set as a non-stop floor and by operating the intercom call button in the car. Since we installed a ring tone generating means that generates different ring tones for each vehicle, it is possible to tell whether a call is coming from inside the car or from a landing on a non-stop floor just by listening to the ring tone of the monitoring intercom. , it becomes possible to take the necessary measures accurately and quickly and quickly rescue trapped passengers.
