Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management control device, and more particularly to a hall call reservation cancellation system for improving operation efficiency.

[0002]

2. Description of the Related Art Conventionally, as a method of canceling a reservation when an elevator other than the reserved elevator first arrives at the reserved floor by a car call for a reserved hall call of elevators in the same group management group, the following methods are available. Proposed.

Japanese Examined Patent Publication No. 61-53977 has a car arrival detection circuit which operates when the load in the car of the first-arriving car exceeds a predetermined value. When the car arrival detection circuit operates, it is assigned first. It is disclosed to cancel the reservation of the elevator.

Japanese Examined Patent Publication (Kokoku) No. 58-44595 discloses that the reservation hall call is canceled when the estimated arrival time of the reservation elevator is longer than a predetermined value.

Further, Japanese Patent Publication No. 59-4354 discloses a method of determining whether or not to cancel a reservation depending on the car that arrives first, the distance from the reservation elevator, and the presence or absence of obstacles.

[0006]

In the first prior art described above, since the predetermined value is fixed, the traffic demand at each time and the traffic demand for each floor are not taken into consideration.
Further, the car calls are reset in both the second and third prior arts, but there is still a problem that the traffic demand at each time and the traffic demand for each floor are not taken into consideration and the reservation cannot be canceled properly. . In addition, it is necessary to inform the passengers that the reservation has been changed so that the passengers can be moved smoothly and there is no leftover.

An object of the present invention is to efficiently change reservations in a group-controlled elevator in consideration of transportation capacity and traffic demand, and also consider travel time so that passengers will not be left over. By controlling
It is to provide an elevator group management control device with good operation efficiency.

[0008]

In order to achieve the above object, the present invention provides a hall call floor assigned to a first elevator, which is different from the hall call before the first elevator. First arrival detecting means for detecting that the vehicle arrives in the same traveling direction as the first elevator under the condition,
Allocation change to cancel the allocation and reservation of the first elevator before the second elevator arrives at the hall calling floor, and to allocate and reserve the second elevator to service the hall calling floor Means, means for extending the door opening time on the floor of the second elevator whose allocation has been changed, and notification means for notifying the waiting passengers of the first elevator hall of the hall calling floor that the allocation has been changed It was configured with. Further, in deciding the allocation change, the service availability of the first-arriving car when servicing the floor is judged from past traffic demand, etc., and based on the result of the judgment, it is decided whether or not to make the reservation change. Means are provided.

[0009]

When the hall call occurs, one elevator is first assigned and reserved. When it was found that the reserved elevator arrived late due to a car call on the middle floor, door opening extension, etc., and the elevator other than the reserved one arrived first due to the car call, the operating status and traffic demand were learned in advance at that time. Judging from the results, predicting the number of passengers waiting on that floor, if the value obtained by subtracting the weight inside the car from the congestion value obtained from the characteristic mode at that time is larger than the predicted passengers, passengers will arrive at the first-arriving elevator It is judged that all passengers can ride and cancel the reservation for hall call to prevent the reserved elevator from servicing the floor without passengers. In addition, by notifying passengers that the reservation has been changed so that the passengers can move smoothly, and by extending the door opening time of the first-arriving car on the floor so that no leftovers occur, good serviceability is achieved. In addition, it is possible to realize elevator group management control with improved operation efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a flowchart of the overall processing of the present invention.

The hardware configuration is a well-known microcomputer control method, and detailed description thereof is omitted here. In the overall process, after the power is turned on, the initial process of S10 is performed by restarting after an error. Next, in S20, data necessary for elevator operation control and learning such as the current operation state is input by signal reception processing from the machine controller. Next, in S30, a registration signal from the hall call registration device installed on each floor is input. Next, in S40, a predicted arrival time table is created for each unit, direction, and floor from the learning data up to the present and the current operation status. In S60, the allocation evaluation value is calculated, and in reference to this evaluation value, the hall call is allocated and reserved in S70. In S80, the occurrence of first-arriving car call is detected, and when the first-arriving car call occurs, it is determined and executed whether to cancel the allocation and reservation, or to reallocate the call to the first-arrival elevator. Then, in S90, hall call allocation and control signal transmission such as reservation cancellation are transmitted to the machine control device. In S100, display guidance data suitable for the operation state is created and transmitted to the display guidance device. It goes without saying that the transmission at this time may be performed via the machine controller. Such S20-S100
Repeat the above process until the power is shut off or a system error occurs.

FIG. 2 shows a flowchart of the first-arriving process of the car call in S80 described with reference to FIG.

First, in S810, the number of loops is set. In this embodiment, loop processing is performed for all units. Next, in S800, in order to grasp the current state, it is determined whether or not the vehicle is stopped at the hall call generation floor. When it is stopped at the hall call generation floor, the process proceeds to S801. When the vehicle is running or stopped by a car call, the process proceeds to S802. In S801, it is determined whether or not the elevator being processed has started to close the door, and if it has started to close the door, the process proceeds to S809 to end the processing of the vehicle. When the service is completed and the door is not closed, that is, when the vehicle is running or is in service on another floor and the stopped door is open, the process proceeds to S802. In S802, it is determined whether or not there is a hall call in the same direction as the arrival elevator on the arrival floor. If there is no hall call, S809
If there is, go to S803.

In step S803, it is determined whether or not there is a hall call on the planned floor or arrival floor of the elevator being processed. If there is no hall call, the process proceeds to step S809, and if there is a hall call, the process proceeds to step S804. In S804, it is determined whether or not the scheduled arrival floor is the special floor such as the standard floor, the lunch floor, the lunch floor, the centralized service floor, the VIP floor, etc., and if it is the special floor, the operation proceeds to S809, otherwise. Proceed to S805. S
In 805, if the arrival floor is the first-arrival reset permission floor, that is, if an elevator other than the reserved elevator arrives first,
It is determined whether or not the reservation can be canceled, and if it is a floor that can be canceled, go to S806. If it is not possible, go to S80.
Proceed to 9. In S806, the load in the car at the arrival of the first-arriving elevator is predicted, and if it is smaller than the predetermined value 1 represented by Formula 1, the process proceeds to S807, and if it is greater, the process proceeds to S812 to perform the door opening extension process, and the occurrence of people who cannot get on Therefore, the reservation cancellation process for the already-allocated elevator is not performed. In S807, it is determined whether or not the estimated arrival time of the assigned elevator is less than or equal to a predetermined value 2 that can be represented by the number 2. If it is less than or equal to the predetermined value, the process proceeds to S809, and if the reservation cancellation process is not performed, the process proceeds to S808. .

[0016]

[Equation 1] Predetermined value 1 = (capacity of car) × X1- (predicted number of passengers on the floor) (Equation 1)

[0017]

## EQU00002 ## Predetermined value 2 = (average waiting time) .times.X2 (Equation 2) In S808, it is determined whether or not the car to which the hall call is assigned is scheduled to stop at a floor in the vicinity of the scheduled floor. If there is no scheduled stop floor, the flow proceeds to S809. If there is a stop schedule, the flow proceeds to S811 to cancel the reservation of the machine reserved for the hall call and change the allocation to the first-arrival elevator, and the flow proceeds to S812.

In step S809, it is determined whether or not the processing for all units has been completed. If the processing has been completed, the first-come-first-served processing is completed. If not completed, the processing returns to S800 and the processing of the next machine is repeated. As described above, in the present process, it is determined whether or not the elevators to which calls have been assigned to the existing halls are scheduled to stop near the arrival floor, and cancellation of the reservation and extension of the door opening time are performed.

However, according to the present invention, the elevator scheduled to arrive in S806 predicts the load inside the car at the time of departure from the arrival floor, and when the load inside the car becomes a predetermined value 1 or more,
The process may proceed to S809, and when the value is less than or equal to the predetermined value, the process may proceed to S811 and the allocation may be changed, and the door opening time of the first-arriving elevator may be set to end the post-extension processing.

If it is determined in S805 that the floor is the first-arrival reset permission floor, the process proceeds to step S807, and if the expected arrival time of the car for which the hall call is reserved is a predetermined value 2 or more, the process proceeds to step S811 to reserve the hall call. Alternatively, the reservation of the elevator may be canceled, the reservation may be changed to the first-come-first elevator, the door opening time may be extended, and then the process may be terminated.

The above equations 1 and 2 are for calculating the predetermined values 1 and 2 in the processing of FIG. 2, and Table 1 shows the constants determined by the feature mode used for the calculation.

[0022]

[Table 1]

As described above, according to the present invention, when a first-arriving elevator is generated and a reservation is changed, the door opening time of the first-arriving elevator can be extended to prevent passengers from being late. Further, by making the reservation change at the hall calling floor until the first-come-first-served elevator starts to close the door, it is possible to prevent useless stop floors and improve operation efficiency.

FIG. 3 shows an example of display and guidance on the fifth floor of this embodiment. t1, t2, t3 indicate the passage of time, H1, H2, H3 are 4-panel displays from Units 1 to 3, and J1, J2, J3 are reserved lights and arrival lights from Units 1 to 3. That is, it turns on when making a reservation and blinks when arriving. K1 and K2 represent hall call registration devices. As you can see from J1-1, t
When it is 1, the hall call in the ascending direction on the 5th floor is assigned and reserved for Unit 1. At this time, the operation status of Unit 1 is represented by H1-1, H1-1A represents the traveling direction and the waiting time up to the fifth floor, H1-1B is the current synchronous floor, and H1-1C is the current. Shows the opening and closing status of the door. Summarizing this, it can be seen from the display of H1-1 that the operation status of Unit 1 is progressing in an upward direction, it still takes time to arrive on the 5th floor, and the door is currently open on the 3rd floor. Two
Reservation etc. for Unit No. 2 is that there is no reservation due to J2-1
Nothing is displayed in 2-1 because it is not a reserved elevator. As you can see from J3-1, Unit 3 is moving down the 5th floor and is arriving soon.

At time t2 after a lapse of time, the allocation and reservation are transferred to the No. 2 machine which is to be reset on a first-come-first-served basis by the processing of FIG. At this point, a display such as H2-2 is displayed, and it is understood that J2-2 has arrived on the fifth floor by blinking. Unit 2 is not a reserved elevator, so we arrived by car. Also, in order to smoothly move passengers from the front of the No. 1 door to the front of the No. 2 door, a display such as H1-2 is fluidly displayed by right shifting. At this time, the reservation lamp is not turned off immediately like J1-2, but is blinked for several seconds to call attention to passengers and then turned off. The blinking at this time is different from the blinking at arrival
F at the time of arrival by performing flicker with a short blinking time like 2
Make a difference with 1 flicker.

At time t3 when the time has further elapsed, the second car displays H2-3 to inform the waiting passengers that there are passengers getting off. Unit 1 continues to display H1-2 until Unit 2 begins to close. In addition, S1 "Reservation has been changed. Please take the elevator next door. The voice guidance such as “” enables passengers to move more smoothly and improves the effect of canceling reservations.

As described above, based on the number of passengers predicted for each floor according to the traffic demand at that time, it is determined whether or not to cancel the car call first arrival floor or the hall call reservation of the first arrival floor, It enables accurate car call first-come-first-served reset and enables efficient operation.

[0028]
