BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control system, and more particularly to an elevator control system that can set a non-stop floor for which a car is prohibited from stopping.

0002

[Prior Art] In so-called multi-tenant buildings used by an unspecified number of users, each user leaves the building at different times, so special consideration must be given to crime prevention according to the leaving time of each user. is necessary. For this purpose, for example,
As disclosed in Japanese Utility Model Publication No. 23867 and Japanese Utility Model Application Publication No. 2378, an elevator control device has been proposed that is equipped with a setting switch that sets a non-stop floor that prohibits the car from stopping on a standard floor for the purpose of crime prevention. has been done. According to the control device according to this disclosure, when a user leaves a specific floor, the last person leaving can set the specific floor being used as a non-stop floor by operating a setting switch on the reference floor. In this way, the car will operate without stopping on the specific floor set as a non-stop floor, so visitors will not be able to get off on the specific floor that everyone has left, and security considerations will be taken into consideration. The elevators will be operated.

0003

[Problems to be Solved by the Invention] In the control device according to the above disclosure, when the last person leaving the specific floor operates a setting switch on the reference floor to set the specific floor being used as a non-stop floor, If by chance the car call for the specific floor has already been registered and the car is in a deceleration state at that time, the car will stop at the specific floor and the elevator door will be in the open state. In this state, once a visitor to a specific floor in the car gets off at the specific floor and the car departs from the specific floor, the elevator will operate without responding to the platform call or car call for the specific floor. Therefore, this visitor is left stranded on a specific floor without being able to use the elevator.

The present invention was developed in view of the current state of this type of elevator control device as described above, and its purpose is to ensure that after a specific floor is set as a non-stop floor, a car call has already been registered and the car is To provide a control device for an elevator that prevents passengers in a car from getting off to a specific floor even if the car is in a deceleration state.

[0005]

[Means for Solving the Problems] The object is to operate a car between multiple floors in response to car call registration and landing call registration, and when the car stops at a registered floor, a door control device The opening and closing of elevator doors is controlled by
Further, a setting switch for setting a non-stop floor for prohibiting the stopping of the car is installed in the elevator control device on the reference floor, and the door control device is installed at the non-stop floor set by the operation of the setting switch. This is achieved by providing a disabling means to disable the operation.

[Operation] With this structure, when the setting switch is operated on the standard floor and a specific floor is set as a non-stop floor, the invalidating means is activated and the operation on the specific floor set as a non-stop floor is activated. The operation of the door control device is disabled. Therefore, even if the car call for the specific floor is already registered when the setting switch is operated, and the car is in deceleration mode at that time and stops at the specific floor, the elevator door will not open and the car will not open. Passengers cannot get off to specific floors set as non-stop floors.

[0006] Therefore, a visitor to a specific floor where all the users have left will not get off the car and be left stranded on the specific floor, and the visitor will not be left behind on the specific floor where all the users have left. Elevators operate without responding to calls and platform calls, and are operated with security considerations in mind.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings (FIG. 1). FIG. 1 is a circuit diagram showing the configuration of the main parts of the embodiment.

As shown in FIG.
A setting switch 2S and a setting relay 2F for setting the second floor as a non-stop floor are connected in series between the DC power terminals P and N on the floor). A setting switch 3S and a setting relay 3F for setting the third floor as a non-stop floor are connected in series with each other. Similarly, a series connection circuit of a setting switch 4F and a setting relay 4F for setting the 4th floor as a non-stop floor;
A series connection circuit of a setting switch 5S and a setting relay 5F for setting a floor to a non-stop floor is connected in parallel between DC power terminals P and N.

Normally closed contact 5Fb is connected between DC power terminals P and N.
2. The normally open contact 5Da and the door controller D are connected in series, and the normally open contact 4Fb2 and the normally open contact 4Da are connected between the connection point of the normally open contact 5Da and the door controller D and the DC power terminal P. A series connection circuit between the normally closed contact 3Fb2 and the normally open contact 3Da, a series connection circuit between the normally closed contact 2Fb2 and the normally open contact 2Da, and the normally open contact 1Da are connected in parallel with each other. Also, between DC power terminals P and N,
Series connection circuit between normally closed contact 5Fb1 and nominal circuit 5C, series connection circuit between normally closed contact 4Fb1 and nominal circuit 4C, series connection circuit between normally closed contact 3Fb1 and nominal circuit 3C, normally closed contact 2Fb1 and nominal circuit 2C The series connection circuit and the calling circuit 1C are connected in parallel with each other.

Here, the normally closed contacts 2Fb2 to 5Fb2 and the normally closed contacts 2Fb1 to 5Fb1 are connected to the setting relay 2F, respectively.
~5F are normally closed contacts, and normally open contacts 1Da to 5Da are normally open contacts of relays (not shown) that are energized when the car is located in the door opening zone of the 1st to 5th floors, respectively. Device D has a function of opening and closing the elevator door when a car arrives at the landing, and call circuits 1C to 5C have functions of registering car calls and landing calls for the 1st to 5th floors, respectively. ing.

In the embodiment configured as described above, the setting relays 2F to 5F and the normally closed contacts 2Fb2 to 5Fb2 constitute the inhibiting means of the invention.

The operation of the embodiment having such a configuration will be explained next. First, when each floor of the building is in use and the last person to leave has not left any floor, the setting switches 2S to 5S are not operated and remain open, and the setting relay is deenergized. For this reason, normally closed contact 2Fb2~
5Fb2, 2Fb1 to 5Fb1 are kept in a closed state, call circuits 1C to 5C and door control device D are in an operable state, and the elevator operates in response to hall calls and car calls for all floors. When the car approaches the stop floor and is located in the door opening zone, a relay (not shown) is energized and one of the normally open contacts 1Da to 5Da is closed, and the door control device D is activated to open the elevator door. Opening and closing are also performed normally.

[0013] For example, assume that the use of the 5th floor has been completed, and
When the last user of the floor to leave operates the setting switch 5S provided on the first floor, which is the reference floor, to the closed state, the setting relay 5F is energized and the normally closed contacts 5Fb2 and 5Fb1 are opened. When the normally closed contacts 5Fb2 and 5Fb1 are opened in this way, the call circuit 5C for the 5th floor becomes inactive, and the elevator operates without responding to car calls and platform calls for the 5th floor. Even if D does not operate and the car stops at the 5th floor, the elevator door will not open.

Therefore, when the last user on the 5th floor to leave operates the setting switch 5S, the car call on the 5th floor has already been registered and even if the car, which is in the deceleration state, stops on the 5th floor, the car call on the 5th floor is already registered. Since the elevator door does not open on the floor, visitors to the fifth floor will not get off the car and be left behind on the fifth floor without being able to use the elevator. Furthermore, since the elevator operates without responding to car calls and platform calls on the 5th floor, where all users have left, the elevator is operated with a crime prevention effect.

[0015]

Effects of the Invention As explained in detail above, the present invention is provided with a disabling means for disabling the operation of the door control device at the non-stop floor set by operating the setting switch. When setting a non-stop floor, a car call has already been registered for that non-stop floor, and even if a car that is in deceleration mode stops at that non-stop floor, the elevator door will not open and the passenger will not be able to stop. No longer will you be stranded on a non-stop floor without being able to use the elevator. In addition, the elevator operates without responding to car calls and platform calls for floors that are set to not stop, and the elevator is operated with security considerations in mind.
