Abstract

PURPOSE:To surely prevent the intrusion to a specific floor and permit the traveling from the specific floor to the other floor by judging that no passenger is present in a cage and directly traveling the cage when the getting-on field call on a specific floor where the destination call register is prohibited is registered. CONSTITUTION:When the intrusion to the third floor is prohibited, an intrusion permission signal 99 to the third floor is set at L, and even if a passenger who gets into an elevator cage which stops on the floor other than the third floor pushes a destination button to the third floor, destination call is not registered. Further, if a passenger is present in the cage, the nonload detection signal 0 becomes L, and even if the call registration signal 103A or 203A for the upper or lower getting-on field on the third floor is set at H, the elevator does not answer the rising or lowering call on the third floor. When a vacant cage is detected, the nonload detection signal 0 becomes H, and the elevator answers to the upper or lower getting-on field call on the third floor, and the cage directly travels to the third floor without answering the call on other floor.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is an office building where an unspecified number of people can come and go. This invention relates to an elevator security operation device that manages entry (exit).

[Prior Art] In recent years, elevators installed in office buildings, etc., especially elevators installed in rental office buildings, etc., where each floor has a different tenant, have been installed at a specified arbitrary location when the building's business is completed. By setting a floor as a specific floor, disabling the destination call in the car with that specific floor as the destination floor to prevent entry (getting off) from other floors, and validating the boarding call for the specific floor, the elevator can be used from this floor. There is a need for a crime prevention device for elevators that allows people to use the elevator to get out.

Conventionally, the third security operation device for such elevators was
The system shown in the figure is known.

This example is for the 1st to 4th floors, with the 3rd floor being the specific floor.

In the figure, the destination call registration device 300 includes destination button signals IB. 2B. 4B is directly input, and the third floor destination button signal 3B is an AND gate! It has been human powered through.

In addition to the destination button signal 3B for the third floor, the AND gate l has 3
A floor entry permission signal 99 has been input.

400 is the hall call registration device, and the up hall call button signal for the 1st and 3rd floors! 02 to 103 and down hall call button signals 202 to 204 for floors 2 to 4 are manually operated, respectively. 6
00 is an elevator operation control device, which is configured to manually input each call registration signal output from the destination call registration device 300 and the hall call registration device 400, and operate the elevator in response to the registered calls. .

In the conventional elevator security operation system configured as described above, if access to the third floor is permitted,
The entry permission signal 99 on the 3rd floor is “H°”, so 3
When the floor destination button is pressed, it is an AND gate! The output of “
H”, the destination call for the third floor is registered in the destination call registration device 300, the elevator serves the third floor, and passengers can get off at the third floor.In addition, the third floor down hall call button or up hall call button is pressed. When it is pressed and the corresponding hall call button signal 203 or 103 becomes "H", the hall call for the third floor down or up is registered in the hall call registration device 400, and the elevator responds to the call.
Passengers waiting on the third floor can ride the elevator to go to other floors.

Next, if entry to the third floor is prohibited, the third floor entry permission signal 99 is "L", so even if you press the third floor destination button 3B, the output of the AND gate 1 will be "L". Therefore, the destination call for the third floor is not registered in the destination call registration device 300. In other words, it is impossible to use the elevator to go to the third floor from other floors. However, if the hall call button 203 or 103 is pressed on the 3rd floor, the elevator will respond in the same way as when access to the 3rd floor is permitted, and passengers waiting on the 3rd floor can go to other floors. It is.

[Problem to be solved by the invention] In the conventional elevator security operation device as described above, even when entry to a specific floor is prohibited by the destination call,
Once the hall call for that specific floor is registered, the elevator will service that specific floor, so passengers in the car will be able to get off on the specific floor that they are prohibited from entering, which poses the problem of insufficient targeting effectiveness. Ta.

This invention was devised to solve such problems, and its purpose is to provide an elevator security operation device that reliably prevents people from entering a specific floor and allows access to other floors from the specific floor. shall be.

[Means for Solving the Problems] In order to achieve the above object, the elevator crime prevention operation device according to the present invention is provided with a security operation device for an elevator that prevents passengers from entering the car when a hall call for a specific floor for which destination call registration is prohibited is registered. The system is equipped with a means for determining that there is no one present, and causing the unmanned car to respond to a hall call on a specific floor and operate directly.

[Function] In this invention, when a landing call for a specific floor to which entry is prohibited is registered, it is determined that there are no passengers in the car,
Since an unmanned car is made to respond to a hall call on a specific floor, even if someone intentionally gets on the car with the purpose of entering a particular floor, that car will not respond to a hall call on a specific floor, and furthermore, during service, other cars may Since the hall call service on the floor is prohibited, boarding from intermediate floors can be prevented, and entry to a specific floor can be surely prevented.

[Example] Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. I is a block diagram showing an example of an elevator security operation device according to the present invention. In the same figure, 300 is 1
A destination call registration device that registers a destination call using the destination button signals IB to 4B for floors to 4th floor, 400 is the up hall button signals 101 to 103 for the 1st to 3rd floors and the down hall button signals 202 to 202 for the 2nd to 4th floors. 204 is a hall call registration device that registers a hall call; 500 is a hall call response permission determination device that determines whether to make the elevator respond to the hall call of each floor outputted from the hall call registration device 400; and 600 is a destination call registration device. Device 300 or hall call response determination device 50
An operation control device that controls the operating direction of the elevator, running and stopping, etc. by the destination call signal and hall call signal output from 0, and 0 is a no-load detection signal that becomes "H°" when the load in the car is no load. , 99 is an approach permission signal that becomes "H" when destination call registration for a specific floor (in this example, the 3rd floor is the specific floor) is permitted, and ■ is a destination button signal 3B and an approach permission signal for the 3rd floor. It is an AND gate that requires 2 people to operate 99.

FIG. 2 is a logic circuit diagram showing the circuit configuration of hall call response permission determination device 500. In the same figure,! 01A~1

~203A is the down-boarding hall call registration signal for the 2nd to 4th floors, 3~
8 is an AND gate, 2I to 23 are OR gates, 1] is an N
The OT gates I01B to 103B are up-hall call response command signals for the ■ to third floors, and 202B to 204B are down-hall call response command signals for the second to fourth floors.

Next, the operation of the elevator crime prevention device of this embodiment configured as described above will be explained. Specific floor (3rd floor)
If entry is permitted, the 3rd floor entry permission signal 9
9 is set to °H °. At this time, a passenger who boarded an elevator car that was stopped on a floor other than the 3rd floor
When the destination button for the floor is pressed, the destination button signal 3B for the third floor becomes "H", and the output of the AND gate 1 becomes "H".

As a result, the destination call registration device 300 registers the destination call for the third floor. 3 output from the destination call registration device Wl300
The floor destination call registration signal is sent to the operation control device 600, and as a result, the elevator responds to the third floor destination call, allowing the passengers in the car to alight at the third floor. Further, the third floor entry permission signal 99 set to "H" is also input manually to the OR gate 21.23 of the hall call response permission determination device 500, so the output of the OR gate 21.23 is “I1° is set. Accordingly, the output of OR gate 2I is applied to one input terminal of AND gate 3.4,
Further, the output of the OR gate 23 is applied to one input terminal of the AND gates 5 to 8. For this reason, AND gates 3 to 8
If any of the up hall call registration signals 101A to I03A for the I to 3rd floors and the down hall call registration signals 202A to 204A for the 2nd to 4th floors, which are applied to the other input terminals of the When the hall call registration signal becomes "H", the outputs of AND gates 3 to 8, which are input manually, become "H", and the AND
Hall call response command signal 101B corresponding to gates 3 to 8
-103B. 202B to 204B are operation control devices 600
will be sent to. As a result, the elevator responds to the hall call registered on each floor, and passengers waiting for the elevator on each floor can get into the car and move to another floor. In other words, when access to a specific floor is permitted, the user can board the elevator from any floor and travel to other floors.

Next, if entry to a specific floor is prohibited, :lW
The entry permission signal 99 for 1 is set to ゜L''.At this time, a passenger who has boarded an elevator car stopped at a floor other than the 3rd floor presses the 3rd floor destination button and the 3rd floor destination button signal 3B is activated. Even if it becomes "H", the output of the AND gate 1 remains at "L", so the destination call for the third floor is not registered. In other words, passengers in the elevator car cannot go to the third floor. Also, if there is a passenger in the car, the no-load detection signal 0 is "L", so the output of the OR gate 2l is "L". Therefore, the third floor which is the other human power of AND gate 3. Up or down hall call registration signal 103A
, 203A is set to ゜H゜, AND gate 3
．． The third floor up or down hall call response command signals 103B and 203B, which are the output signals of No. 4, remain at "L". In other words, the elevator does not respond to calls for going up or going down to the third floor. At this time, the third floor up or down hall call response command signal 103B. On gate 2 with 203B powered by two people
Since the output of 2 is “L”, it is a NOT gate! The output of + becomes “H”, and the output of the On gate 23 becomes “H”.
It is H°. Since the output "H" of this OR gate 23 is inputted to one input terminal of AND gates 5 to 8, the I, which is applied to the other input of AND gates 5 to 8,
2.4th floor landing call registration signal 101A. 202A, +0
If either 2A or 204A is "H", the corresponding output signal of AND gates 5 to 8 is 1, 2.4.

B,204BJ! +<“H°” and the operation control device Wl6
00. As a result, excluding the 3rd floor < 1, 2.4
The elevator answers the floor call.

Next, if entry to a specific floor is prohibited, and
If an unmanned car with no passengers inside the car is detected,
Since the no-load detection signal O applied to one input terminal of the R gate 2l becomes "H", the output of the OR gate 2l becomes "H°". 4, so when the third floor up or down hall call registration signal 103A.203A is set to "H°", the third floor up or down hall call registration signal 103A. Or down hall call response command signal 10
3B. 203B becomes "H". In other words, the elevator responds to the up or down hall call for the 3rd floor. Also, at this time, the 3rd floor up or down hall call response command signal 103B,
When 203B becomes “H”, the output of OR gate 22 becomes “H”.
Since it becomes H°, NOT gate! 1 becomes "L", and the output of OR gate 23 becomes "L". When the output of OR gate 23 becomes "L", the output signals of AND gates 5 to 8 become "L", so that l Floor. 2nd floor. 4th floor up or down hall call response command signal 101B, 102B. 20
2B. 204B becomes "L'. That is, 1st floor. 2nd floor, 4th floor.
The elevator will no longer respond to calls to go up or down floors. As a result, when an unloaded car is responding to an up or down landing call on the 3rd floor, it will go straight to the 3rd floor without responding to a landing call on another floor, leaving the elevator unattended. It will be possible to reach the third floor.

In the above embodiment, data obtained from the load inside the car is used as the no-load detection signal as the means for detecting an unmanned car, but means for detecting the presence or absence of a destination call button signal within the car may also be used. It is also possible to use a camera to detect the presence or absence of passengers, and the purpose of the present invention is not hindered by the unmanned car detection means. Although this embodiment has been described in the case of one elevator, the same effect can be achieved even if a group of elevators is managed.

[Effect of the invention] As explained above, the present invention provides an unmanned car detection signal,
A hall call response permission determination device is installed to process a signal prohibiting entry to a specific floor, thereby limiting the cars that respond to a hall call on a specific floor to unmanned cars, and driving these cars directly to the specific floor. As a result, it is possible to reliably prevent people from entering a specific floor, and also to prevent other disasters incidental thereto.
