Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an elevator operation system, and in particular, in a group control elevator that selects and allocates an optimal car for a hall call, it is possible to avoid long waiting times for hall calls. To provide an operating device of a system that prevents car calls from occurring and permits only car call registration within a range that does not result in long waiting times.

[Conventional technology]

In recent years, a system has been adopted for group management of elevators, in which an optimal car is selected and assigned to serve each hall call that occurs.

In such a system, one elevator is assigned to a hall call on multiple floors, and sometimes to a hall behind the car in the traveling direction.

The details will be explained below with reference to FIG.

Figure 4 shows an explanatory diagram of the operation of an elevator in a 15-story building. Floor 10F
~15F can now be serviced. 2 is the express section corresponding to the 2nd floor to the 9th floor, and the round IC on the 1st floor IF represents the 1st floor car call of car B, and the 14th floor 14F
The circle mark 14C represents the car call on the 14th floor of car A, and the triangle mark 12U on the 12th floor represents the ascending hall call on the 12th floor.

Car A is currently traveling up the 13th floor with a car call on the 14th floor (last car call 14C), and is about to decide to stop at the 14th floor.

Here, assuming that car A has already been assigned to the ascending hall call 12U on the 12th floor 12F, when car A stops at the final car call 14C on the 14th floor, the next direction to depart from is the 12th floor 12F. The train will turn around and stop in the direction of exit, and the exit direction arrival light will be lit at the landing to indicate this.

However, if there is a passenger exiting the car at the landing while the door of car A is open on the 14th floor, that passenger will board car A and press the car call button for his/her destination. If the passenger's destination floor was the 1st floor IF, car A would descend to the 1st floor without turning around on the 12th floor in order to service the 12th floor ascending hall call, and after traveling to the 1st floor. Then, the vehicle turns around and travels up to the 12th floor, and then responds to the call at the ascending hall. As a result, passengers on the 12th floor will have to wait for a long time to get up, which is undesirable as it makes passengers on that floor feel anxious.

In addition, in recent years elevators have already turned on service guide lights that indicate which car will be assigned and serviced for a hall call. Changing the number is undesirable because passengers waiting in front of the service plane will have to move again.

[Problem that the invention seeks to solve]

As mentioned above, in the conventional elevator operation system, the direction in which the elevator stops when a decision is made to stop is fixed, except for basements and specific floors. , it is possible to register car calls up to the terminal floor in that direction, so if a car that has stopped in a direction to service a hall call receives a car call from the above-mentioned hall call or beyond by an unexpected passenger. , the car call will be given priority service regardless of the waiting time for the hall call,
As a result, there is a problem in that some passengers have to wait for a long time, which makes waiting passengers feel irritated, and the service provided to passengers waiting in the hall is degraded.

This invention was made in order to solve the conventional problem as described above, and it takes into account the conditions behind the hall call to which a car is assigned and controls the direction when determining the direction so that the hall call does not have to wait for a long time. In addition, it is an object of the present invention to provide an elevator operating device that can quickly service assigned hall calls without having elevator operation affected by unexpected occurrences of car calls.

[Means for solving problems]

The elevator operating device according to the present invention has a function of determining whether or not there is a hall call assigned behind the elevator car when the elevator car stops at the final car call, and a function of determining whether there is a hall call assigned behind the elevator car and whether the car to which the hall call has been assigned is the last car call. A function that predicts and calculates the duration from the end of the service until the assigned hall call is serviced, and when the duration of the hall call is predicted to be within a predetermined value, the car The vehicle is provided with a control means having a function of stopping and displaying the direction opposite to the direction in which the vehicle should start traveling next time.

[For production]

In this invention, if the duration of the hall call calculated by the control means is predicted to be longer than a predetermined time, the car that served the last car call has a direction opposite to the direction in which it should depart next. to avoid disrupting elevator operation by restricting car call registration due to new landings occurring for more than a predetermined time on that floor, and to avoid long waiting times for assigned hall calls. It will be served.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is a system configuration diagram showing an example of an elevator operating device according to the present invention, in which 20 is a program memory 2 that controls and manages data memory, input/output devices, etc., and executes tasks necessary for controlling elevator operation. A central processing unit (hereinafter referred to as CPU), 21, is a lll1m program necessary for operating the elevator.

A memory composed of a ROM that stores a control program, etc. for the direction control when determining the direction of the arrival light and the arrival light direction determination routine that determines the car call entry RtliH of the car assigned to the hall call, 22 is the calculation result of the CPU 20, etc. It is a RAM-configured memory that temporarily stores 21.22
is connected to the 1" CPU 20 via the bus 23. Also, 24 and 25 are interfaces connected to the CPU 20 via the bus 23, and one of the interfaces 24 has an elevator as shown in FIG. A hall call registration button 26 provided on the front wall of the hall is connected to input car status information 27 such as a car call registration button, and the other interface 25 is connected to the car status information 27 as shown in FIG. As shown, a landing direction arrival light 28U and a landing direction arrival direction arrival light 2 provided on the curtain plate 31 of the elevator entrance 30 are provided.
8D is connected to a hall destination floor display section 29 that displays the service floor.

Next, the operation of this embodiment using the system configuration as described above will be explained with reference to the flowchart shown in FIG. 2 and FIG. 4.

Figure 2 shows the arrival light direction regulation routine in this invention.
This routine is added to the normal operation control program, and is executed when the car stops at the final car call while the car is moving in a certain direction.

Now, if car A receives a car call on the 14th floor and decides to stop at 14F on the 14th floor as shown in FIG. 4, the arrival light direction determination routine shown in FIG. 2 starts.

That is, in step S1, car A is the last car call.

Determine whether or not to stop. At this point, car A stops at the final car call to the 14th floor, so it moves to the next step S2.
It is determined whether there is a hall assignment call in the same direction as the car A behind it. In the operation diagram shown in Figure 4, there is a 12th floor ascending assignment in the background, so the determination result in step S2 is r
YESJ, move to the next step S3 and move to the next step S3.
Calculate the waiting time when the person answers the assigned hall call directly. That is, the predicted duration of the 12th floor ascending hall call is calculated in the case where car A, after servicing the 14th floor car call, goes directly to service the 12th floor ascending hall call.

For example, the time that has already passed since the hall call was registered is 5 seconds, the time to stop at 14M is 10 seconds, the time to travel from the 14th floor to the 13th floor is 2 seconds, and the time to travel from the 13th floor to the 12th floor. Assuming that 2 seconds, the predicted duration t is: t,=5+10+2+2=19 seconds...-(1). However, to simplify the explanation, the time for one stop is 10 seconds, and the time for traveling from the N floor to the N+1 floor is 2 seconds.

Then, the above calculation result is compared with a predetermined value in the next step S4. Now, if the predetermined value is 40 seconds, the determination result in step S4 is YESJ, and by moving to step S5 and executing the reversal stop display process, car A is reversed and stopped, that is, stopped in the downhill direction. It turns out.

Next, in step S6, assuming that a passenger boards car A on the 14th floor and a car call occurs in the direction of car A (disembarking direction), the waiting time of the assigned landing call is calculated from the farthest car call. Calculations are performed sequentially for the nearest car call.

For example, when car A stops on the 14th floor, assuming that the passenger who boarded the car has registered a car call on the farthest floor, the prediction for the 12th floor ascending hall call is calculated as in equation (1) above. The duration t is t=5+10+2+2+2+2+(2x9)+10+(
2×9)+2+2=73 seconds. This calculation result is compared with a predetermined value (for example, 40 seconds) in the next step S7, but since the determination result is rNOJ, the process returns to step S6 and the next calculation is performed for a distant car call.

Here, if the next farthest car call is on the 10th floor, then 1
Similarly, the predicted duration t of the second-floor ascending hall call is t=5+10+2+2+2+2+10+2+2=37 seconds. This calculation result is compared to determine whether it is below a predetermined value in step S7. Duration time t=3 in this case
7 is less than the predetermined value (40 seconds), so the next step S
Go to 8 and then 10 as the furthest serviceable car call.
Select a floor, and in the next step S9 enable car call registration in the range from the 14th floor to the 10th floor, restrict car call registration on the 10th floor and above (9th floor to 1st floor), and then proceed to the next step At 310, a message indicating that service is available on the 10th to 14th floors is displayed on the hall destination floor display section 29 as shown in FIG.

Therefore, car A lights up the 14th floor factorial arrival light 28D, stops in the direction of descent, and registers a car call up to the 10th floor.If car call service reaches the 10th floor and the car stops. If a passenger planning to go to the 9th floor boards the aircraft while
After traveling to the 9th floor, the direction is reversed and stopped at the direction shown in step S5 of FIG. 2 on the 9th floor, and the train returns to the ascending direction, where it will service the hall call on the 12th floor again. Also, 14
If no one gets on board at Pl, or if a passenger who wants to go to the 12th floor gets on board, the train will go straight to the 12th floor for service.

In addition, if the predetermined value in step S4 is set to 15 seconds, when the car A stops on the 14th floor, step S4 in FIG.
ll, the aircraft will stop in the same direction, go up to the 14th floor, stop in the ascending direction, and turn on the arrival light 28U. As a result, if there is no car call in the ascending direction, the car will go directly to the 12th floor after closing the door, and even if there are passengers descending on the 14th floor, the service will not be disrupted by these passengers. Allocated boarding service. Also, in this case, step 31
1, the vehicle was stopped in the same direction, but it is also possible to stop the vehicle by turning off the arrival display at the landing (in this case, the arrival light 28U).

On the other hand, if the determination in step S2 is "NO", the process proceeds to step 312, where it is determined whether or not a hall call in the opposite direction to car A is assigned behind the car. (15th floor descending assignment) proceeds to step 813, where the car A is reversed and stopped (stopped in the ascending direction), and this is indicated by the arrival light 28U.

If the determination result in step 812 is "NO", the process proceeds to step 314, where it is determined whether the location is underground or on a specific floor.If rYEsJ, the process proceeds to step 315, where a specific stop display is performed. If rNOJ, step 81
Move to 1.

〔Effect of the invention〕

As described above, according to the present invention, when the waiting time at the assigned landing call for a car is likely to be longer due to an unexpected car call, the waiting time is prevented from increasing by allowing the car to go directly to that landing. When the elevator is within a certain range, it is possible to quickly reach the destination floor even if the number of passengers is reduced as much as possible by calling, so it is possible to reduce the number of long waiting hall calls and to provide efficient elevator service. This makes it possible to shorten the waiting time at the boarding stations throughout the building.
