Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an elevator control device.

(Prior Art) Elevators that have multiple entrances and exits on the same floor have been known for a long time, but generally speaking, in an elevator control device that controls the operation of an elevator that has multiple entrances and exits on the same floor, If the vehicle lands and stops on a floor with multiple entrances and exits, it is prohibited for safety reasons to open both the front and rear doors at the same time. Priorities are determined in the following order: car calls, rear car calls, front hall calls, and rear hall calls, and consideration is given to controlling responses in the order of priority.

FIG. 4 shows an elevator system equipped with such a plurality of entrances on the second floor, and the elevator car 1 has entrances on both the front side and the back side on the second floor. Respond to any hall call or car call,
You can open and close the door of the entrance/exit on the responding side.

(Problem to be Solved by the Invention) However, in such a conventional elevator control device that controls the operation of an elevator equipped with a plurality of entrances and exits, the fourth
As shown in the figure, if there are passengers waiting on both the front and back sides of the second floor, and each of them operates the hall call button to register a hall call in the same descending direction, the passenger in the car will be waiting at the front of the second floor. When the car call button on the side is selected and car 1 lands on the second floor in the descending direction and the door on the front side of the second floor is opened, the passengers waiting at the landing on the second floor will hear the door on their side being opened. However, the passenger waiting on the back side of the second floor is unable to get into car 1 because the front door is open even though the car selected in the descending direction has landed on the second floor. The door on the side of the car will not open, so you cannot get into car 1 right away. Then, after the front door closes, the rear door is finally opened, and the passengers waiting on the rear side can board the car.

For this reason, in elevator control devices for elevators with multiple entrances on the same floor, priority is determined based on the order in which the doors open, so if you operate the hall call button on the side with the lowest priority. Customers may be forced to wait for a long time, and in such cases they are not informed of the reason, creating a sense of distrust and anxiety in the customers, wondering, ``Will this door ever open?'' There was a problem.

This invention was made in view of these conventional problems, and the elevator is stopped on a floor where multiple entrances can be opened and closed, and the door on the opposite side from the side where you are waiting is open. Sometimes, when the waiting passengers are called to the platform, the notification means is used to inform them that the door on the other side is open, so please wait a little longer, thereby creating a sense of distrust and anxiety among the waiting passengers. It is an object of the present invention to provide an elevator control device that does not cause

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an elevator control device that controls the operation of an elevator that has a plurality of entrances and exits on the same floor. a car position detection means for detecting that the car has stopped on a floor with the plurality of entrances; and a door opening/closing detection means for detecting the opening and closing of the door on each entrance/exit side. ,
A notification means for notifying a message to the effect that the door on the opposite side is open and to wait for a while, and a door to one side of the car being opened, and a landing call from a landing on the other side are registered. and a control means for causing the notification means to perform a notification operation when the notification is detected.

(Function) In the elevator control device of the present invention, when an elevator reaches the floor and stops on a floor with multiple entrances and exits,
When a hall call is registered in the same direction from each entrance/exit on the floor, the control means operates the notification means to notify the passengers waiting at the entrance on the opposite side of the entrance with the door open. It is possible to prevent waiting customers from feeling distrustful or anxious by informing them that the door on the other side is open and that they should wait for a while.

(Example) Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.

FIG. 1 shows an embodiment of the present invention, and is an embodiment of an elevator control device for an elevator having entrances on the front side and the rear side on the second floor as shown in FIG. A front hall call button 11 is provided at the front landing, and a rear hall call button 12 is provided at the rear landing. The signals from these hall call buttons 11 and 12 are input to a hall call registration circuit 13, where elevator hall call registration processing is performed.

Furthermore, the elevator control device of this embodiment includes a car position detection circuit 14 for detecting the position of the elevator car 1, and a door open detection circuit 15 for detecting whether the front door or the back door is open. , an indicator light lighting circuit 16 as a notification means for notifying when the door on the opposite side is open; a hall call registration status of the hall call registration circuit 13; a car position detection status of the car position detection circuit 14; and a comparison circuit 17 as a control means for inputting the door open side detection status of the door open side detection circuit 15 and controlling the operation of the indicator light lighting circuit 16.

Figure 2 shows the exterior of the hall on the front side of the second floor, with a front hall call button 11 on the wall near the elevator door 18, an indicator 19 that displays the position of the elevator car, and a message saying, ``Open the door on the opposite side.''It's open. Please wait a moment."
An indicator light 20 that displays the following is installed.

Next, the operation of the elevator control device having the above configuration will be explained.

Passengers waiting at the platform should press the platform call button 11 from the platform on the side they are on.
．． When you press 12 to register a hall call, this is input to the hall call registration circuit 13, where the hall call buttons 11 and 12 are pressed.
At the same time as determining which one of the buttons was pressed, the hall call is registered and passed to the elevator operation control device (not shown), and the elevator operation control device receives the signal and then sends the car call of the passenger in the car. After receiving the registration, the elevator car is moved to the floor where the car call or hall call has been registered according to a predetermined procedure.

When the car position detection circuit 14 detects that the elevator car approaches a predetermined stop floor, the elevator operation control device slows down the car speed, enters a landing position, and stops when the car reaches a predetermined stop position.

When the car stops, the doors are opened, and the order in which the doors are opened is prioritized in the following order: front car call, rear car call, front hall call, and rear hall call. Accordingly, the door with the higher priority will be opened, and the door open side detection circuit 15 detects which side of the door is open and provides it to the comparison circuit 17.

The comparison circuit 17 detects from the signal from the car position detection circuit 13 that hall calls are registered simultaneously from the front and rear sides of the second floor, which has multiple entrances, in the same direction. When a signal is received to detect that the car has stopped on the second floor, and a detection signal indicating whether the front door or the rear door is open is input from the door open side detection circuit 15, Giving a lighting command to the indicator light lighting circuit 16 on the side opposite to the side where the door is currently opened,
A message is sent to the passengers waiting for the platform to call, ``The door on the other side is open. Please wait for a while.''

The operation of this elevator control device will be explained in more detail according to the flowchart shown in FIG. Note that this flowchart explains the operations when the front door is opened first according to the priority order, but when the rear door is opened first, the operations shown in 0 will be performed. .

It is first determined whether the elevator car has stopped on a floor with a plurality of entrances and exits (Step S1), and when the elevator car has stopped on a floor with a plurality of entrances and exits, the front door is opened according to the priority order (Step S2).

Next, it is determined whether or not the rear hall call is registered (step S3). If there is a call registered from the rear hall call, the indicator light lighting circuit for the rear hall is activated, and the "opposite side" The message "The door is open. Please wait for a while." is displayed to inform the waiting passengers at the rear boarding area (step S4).

Next, when the front door is closed, the rear door is opened and the indicator light lighting circuit that was turned on until then is turned off.
Make the message invisible (steps S5 and S6).

In this way, in an elevator with multiple entrances and exits, when hall calls are registered from multiple entrances at the same time, there is a priority order, and even if a car arrives, the door cannot be opened immediately. It is possible to kindly inform the passengers waiting at the boarding station of the reason, thereby preventing them from feeling distrustful or anxious.

In the above embodiment, a message is displayed, but the message may be announced by voice along with the message display or alone.

[Effects of the Invention] As described above, according to the present invention, when a hall call is registered from a plurality of entrances on a floor with a plurality of entrances and exits, when a car lands on the floor and When the door on that side is open, passengers waiting at the landing on the side where the other door is located are informed that they should wait for a while because the door on the other side is open. Therefore, customers who are waiting may become suspicious if the car is stopped on the floor they are on but the door will not open, or they may be worried that they will be forced to wait for a long time for no reason. This will help improve the quality of the service.
