Description

Description: TECHNICAL FIELD The present invention relates to an elevator driving device, and in particular, in a group control elevator of a system that selects and allocates an optimum car to a hall call, the hall call does not wait long. In addition to the above, there is a need to obtain a driving device of a system that permits only car call registration in a range that does not result in long waiting.

[Conventional technology]

In recent years, as a group management system for elevators, a system has been adopted in which an optimal car is selected for each generated hall call and assigned so as to be serviced.

In such a system, one elevator is assigned to hall calls on a plurality of floors, and in some cases, is assigned to a hall behind the car in the traveling direction.

The details will be described below with reference to FIG.

Figure 4 shows the elevator operation diagram for a 15-story building, where A is the car of Unit A, B is the car of Unit B,
These cars A and B can serve the 1st floor 1F and the 10th to 15th floors 10F to 15F. 2 is the express section corresponding to the 2nd floor to the 9th floor, and the circle 1C on the 1st floor 1F represents the car call on the 1st floor of car B, and the circle 14C on the 14th floor 14F is the car on the 14th floor of car A. It represents a car call, and the triangular mark 12U on the 12th floor represents an ascending hall call on the 12th floor.

Car A now has a car call on the 14th floor (last car call 14C) 1
He is traveling up the 3rd floor and is about to decide to stop on the 14th floor.

Assuming that car A is already assigned to the ascending landing call 12U on the 12th floor 12F, car A is the last car call 14C on the 14th floor.
When you stop at 12th floor, 12F
In the direction of, the vehicle stops inversion in the descending direction, and the descending arrival light indicating that is turned on at the hall.

However, while car A is open on the 14th floor, it is a fixed method except for basements and specific floors, and for cars that have stopped in a certain direction, the terminal floor in that direction is fixed. Since car call registration is possible, if a car call beyond the above-mentioned landing call occurs due to an unexpected passenger in a car that stopped in a direction to service the landing call, wait for that car call There is a problem that the service is given priority regardless of the situation, and as a result, a landing call waiting for a long time occurs, making the waiting passengers feel frustrated and degrading the service to the waiting passengers.

The present invention has been made to solve the above-mentioned conventional problems, and controls the direction when determining the direction so that the hall call does not wait long considering the conditions behind the hall call to which the car is assigned. At the same time, it is an object of the present invention to provide an elevator driving device that can promptly service a hall call assigned without being influenced by elevator operation due to unexpected car call generation.

[Means for solving problems]

An elevator operating system according to a first aspect of the present invention is
When the car stops at the last car call, the back call determination means that operates when there is an assigned hall call behind the driving direction of this car and the waiting time when the car responds directly to the assigned call behind the car A waiting time calculation means for calculating and a display means for holding the driving direction up to that time and displaying it in the hall when the car stops at the last car call when it is determined that this waiting time exceeds a predetermined value Be prepared.

Further, in the elevator driving apparatus according to the second aspect of the present invention, when the car stops at the final car call, there is a back call determining means that operates when there is an assigned hall call behind the car in the driving direction, and the car is behind. A first waiting time calculation means for predicting and calculating a waiting time when a call is directly made and responding to the assigned call, and a direction when the car stops at the final car call when the waiting time is determined to be less than or equal to a predetermined value. And a second waiting time calculating means for predicting and calculating a waiting time when responding to a car call registered in a car and then responding to an assigned call behind the car. And second display means for restraining the car call registration beyond the farthest car call whose waiting time is equal to or less than a predetermined value and displaying the car call registration at the hall.

[Action]

In the first aspect of the present invention, when it is predicted that the calculated waiting time of the back call exceeds a predetermined value, when the car stops at the last car call, the direction up to that time is maintained, and Since this is displayed at the landing, when the car stops for the final car call, passengers in the opposite direction do not board and the car can go straight to the back call.

Further, in the second invention, when the calculated waiting time of the back call is predicted to be less than or equal to a predetermined value, the direction is reversed when the car stops at the final car call, and further, the car call Since the waiting time for responding to a back call after responding to is less than the above predetermined value, the car call registration other than the car call is restricted. Therefore, the car call is also answered before responding to the back call.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a system configuration diagram showing an example of an elevator operating apparatus according to the present invention, in which 20 is a program memory,
A central processing unit (hereinafter referred to as CPU) that manages the control of data memory and input / output devices to perform the work required for elevator operation control, 21 is the control program required for elevator operation, and when the arrival light direction is determined Direction control and the memory of the ROM configuration that stores the control program of the arrival light direction determination routine that determines the car call registration range of the car assigned to the landing call, and 22 is the RAM that temporarily stores the calculation results in the CPU 20. Memory of the configuration, these memories 21 and 22 are bus
Connected to CPU 20 via 23. Also, 24 and 25 are buses
An interface connected to the CPU 20 via 23,
As shown in FIG. 3, the landing call registration button 26 provided on the front wall of the elevator hall is connected to the one interface 24, and the car status information 27 such as the car call registration button is input. Further, on the other interface 25, as shown in FIG. 3, the hall ascending direction arrival light 28U and the hall ascending direction arrival light 28D provided on the curtain plate 31 of the elevator doorway 30 and the hall for displaying the service floor. Destination floor display section 2
9 is connected.

Next, the operation of the present embodiment having the system configuration as described above will be described with reference to the flowchart shown in FIG. 2 and FIG.

FIG. 2 shows the arrival light direction determination routine in this invention.
This routine is added to a normal operation control program, and this routine is executed when the car is running in a certain direction and is stopped at the final car call.

Car A now has a car call on the 14th floor as shown in Fig. 14
If it is decided to stop at the 14th floor, the arrival light direction determination routine of FIG. 2 starts.

That is, in step S1, it is determined whether or not the car A is stopped at the final car call. Here, car A stops at the final car call to the 14th floor, so move to the next step S2 and move car A behind it.
It is determined whether there is a hall allocation call in the same direction as. Fourth
In the operation explanation diagram shown in the figure, there is a climbing allocation on the 12th floor in the back, so the determination result in step S2 is "YES", and the process moves to the next step S3 where the car A goes straight to the assigned hall call. Calculate the waiting time when responding. That is, after car A finishes the service for the car call on the 14th floor, the expected duration of the 12th floor ascending landing call is calculated when the car A goes straight to the 12th floor ascending landing call.

For example, the time that has already passed since the hall call was registered is 5 seconds, the time to stop on the 14th floor is 10 seconds, the traveling time from the 14th floor to the 13th floor is 2 seconds, and the traveling from the 13th floor to the 12th floor. If the time is 2 seconds, the predicted duration t is t = 5 + 10 + 2 + 2 = 19 seconds (1). However, in order to simplify the explanation, it is assumed that one stop time is 10 seconds and the traveling time from the Nth floor to the N + 1th floor is 2 seconds.

Then, the above calculation result is compared and determined with a predetermined value in the next step S4. Now, assuming that the predetermined value is 40 seconds, the determination result in step S4 is "YES", and step S5
By performing the reversal stop display processing after shifting to (1), the car A stops reversing, that is, stops in the descending direction.

Next, in step S6, the passengers board the car A on the 14th floor,
Assuming that a car call has occurred in the direction of the car A (downward direction), the waiting time of the assigned hall call is sequentially calculated from the farthest car call to the nearest car call.

For example, if car A stops on the 14th floor, and the passengers boarding the car register the car call on the farthest floor,
Similar to the above equation (1), the predicted duration t of the 12th floor ascending hall call is t = 5 + 10 + 2 + 2 + 2 + 2 + (2 × 9) +10+ (2 × 9) + 2 + 2 = 73 seconds. This calculation result is compared and determined with a predetermined value (for example, 40 seconds) in the next step S7, but since the determination result is "NO", the process returns to step S6 again, and the calculation is performed for a distant car call next. To do.

Here, if the next distant car call is on the 10th floor, the expected duration t of the 12th floor ascending hall call is similarly t = 5 + 10 + 2 + 2 + 2 + 2 + 10 + 2 + 2 = 37 seconds. This calculation result is compared and determined in step S7 as to whether it is less than or equal to a predetermined value. Since the duration t = 37 in this case is less than the predetermined value (40 seconds), the process proceeds to the next step S8, the 10th floor is selected as the farthest serviceable car call, and the 14th floor is selected in the next step S9. Car calls can be registered from the 10th floor to the 10th floor, and car calls from the 10th floor and beyond (9th floor ~
(1st floor) Registration is restricted, and in the next step S10, the fact that service is possible on the 10th to 14th floors is displayed on the hall destination floor display section 29 as shown in FIG.

In this way, when it is determined that the waiting time is short in step S4, the car call is answered as much as possible, and then the back call is answered.

Therefore, the car A lights the arrival light 28D at the hall on the 14th floor and stops in the descending direction, and it is possible to register the car call up to the 10th floor. If the car is stopped, it is planned to go to the 10th floor. When passengers board the vehicle, after traveling to the 10th floor, the direction is reversed and stopped on the 10th floor at the direction determination shown in step S13 of FIG. become. Also, if there is no passenger on the 14th floor, or if there is a passenger who wants to go to the 12th floor, the service will go straight to the 12th floor.

Also, if the predetermined value in step S4 is set to 15 seconds,
When the car A stops on the 14th floor, it proceeds to step S11 in FIG.
It will turn on 28U. As a result, if a car call does not occur in the ascending direction, after closing the door, you will go straight to the 12th floor, even if there are passengers in the descending direction on the 14th floor,
Since the driving direction is set to the ascending direction, passengers in the descending direction can service the assigned hall call on the 12th floor without being disturbed. Further, in this case, although the vehicle is stopped in the same direction in step S11, it is also possible to stop by turning off the arrival display at the hall (in this case, the arrival light 28U).

In this way, if it is determined in step S4 that the waiting time is long, it is possible to go straight to the back call unless a car call in the ascending direction occurs.

On the other hand, in the above step S2 when the 14th floor is stopped,
If "NO" is determined, the process proceeds to step S12, and it is determined whether or not a hall call in the opposite direction to the car A is assigned to the back, and if it is determined to be (decision assignment on the 13th floor)
Advances to step S13, the car A is stopped in the reverse direction (stopped in the descending direction), and the arrival light 28D is displayed to that effect.

Further, when the determination result in step S12 is "NO", the process proceeds to step S14, it is determined whether the basement or the specific floor, "Y
If "ES", the process proceeds to step S15 and a specific stop display is performed. If "NO", the process proceeds to step S11.

〔The invention's effect〕

As described above, according to the first aspect of the present invention, when stopping at the final car call when the waiting time of the back call is predicted to exceed the predetermined value, the direction up to that time is maintained and this is used as the hall. Since it is displayed, when the car stops at the last car call, passengers in the opposite direction do not get on board, the car can go straight to the back call, and it is possible to prevent waiting customers for back calls from waiting for a long time effective.

In the second invention, when it is predicted that the waiting time of the back call is less than or equal to a predetermined value, the direction is reversed when stopping at the final car call, and the car call is answered and then the back call is answered. The car call registration other than the car call whose waiting time is less than or equal to the above specified value is restricted, so that the car call is answered before the back call is answered, and the wait for the back call is not waited for a long time. In addition, car calls can be provided, and efficient elevator service can be provided, and the waiting time at the hall of the entire building can be shortened.
