Abstract

PURPOSE:To attempt previous prevention of long waiting and improvement of operation efficiency by providing a reassignment means for reassigning all elevator hall calls assigned to an elevator or elevator hall calls under specific conditions when door opening is continued for specific periods or more or when an opening extending button is operated. CONSTITUTION:Conditions for performing reassignment by a reassignment request detecting program SF15 are detected in an operation control program SF14 on the basis of input information. When the conditions are satisfied, the request of reassignment is output to a call assignment program SF16. That is, door opening information of an elevator and a door opening extending button information are input from an elevator controlling data table. And reassignment request command is output to the control program after detecting the fact that the specific time passes. In the call assignment program SF16, the optimum elevator call is assigned according to the reassignment request on the basis of the arrival expected time to be output from an arrival expected time calculating program SF17.

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 reallocation means for reallocating a hall call in the intentional continuation of door opening (loading and unloading).

[0002]

2. Description of the Related Art Conventionally, if a door is intentionally kept open (carrying in and out of luggage, etc.), the prediction will be incorrect, so that the hall call assigned to the elevator tends to wait long. As means for solving it, as described in JP-A-1-43486, when the open extension button is operated,
There was a method of temporarily excluding from the group management and assigning all assigned hall calls to other units.

[0003]

The above-mentioned prior art is related to the opening extension button, and there is no known example of other intentional continuation of door opening. Further, in the above-mentioned conventional technology, since all assigned hall calls are assigned to other units, there is a drawback that even hall calls with a short waiting time that are unnecessary for reallocation are reassigned.
In particular, in the case of an elevator that uses an immediate reservation system, reservation changes will occur frequently, resulting in deterioration of service to waiting customers.

An object of the present invention is to solve the above-mentioned problems of the prior art, to prevent long waiting for intentional continuation of door opening (carrying in / out of luggage, etc.) and to improve operation efficiency.

[0005]

Reassignment means for reassigning all the hall calls assigned to the elevator or hall calls under a predetermined condition when the door is continuously opened for a predetermined time or when the opening extension button is operated. Is provided.

[0006]

The re-allocating means predicts in advance that a hall call already assigned to the elevator will wait long, and re-allocates the hall call, so that long waiting can be prevented. In addition, the entire balance can be maintained without reallocating hall calls that do not require reallocation with a short waiting time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to specific examples shown in FIGS.

FIG. 2 is an overall hardware configuration diagram of an embodiment of the present invention.

The elevator group control device MA includes a microcomputer M1 that controls elevator operation and a microcomputer M2 that controls simulation. Data communication is performed between the microcomputers M1 and M2 by a serial processor SDAc via a communication line CMc. . The detailed structure and operation of the SDAc are disclosed in JP-A-56-37972 and JP-A-56-37973. Although the microcomputer M2 is also used in this embodiment, the microcomputer M1 may be entirely used.

A call signal HC from a hall call device HD is connected to a microcomputer M1 for controlling elevator operation via a parallel input / output circuit PIA, and door opening / closing, car acceleration / deceleration commands, etc. No. control microcomputers E _{1 to} En for controlling the elevator (herein, the elevator is assumed to be the nth machine) are connected to the same serial communication processors SDA _{1 to} SDAn as above through communication lines CM _{1 to} CMn. I am doing it.

On the other hand, the microcomputer M2 inputs / outputs in parallel a signal PM from the power-saving target setting device PD, which gives information necessary for determining the optimum operation control parameter for simulation.

Further, in the machine control microcomputers E _{1 to} En, control input / output elements EIθ _{1 to} EIθn composed of car call information necessary for control, various elevator safety limit switches, relays, and response lamps are connected to communication lines. SI θ ₁ ~ SI
They are connected via θn.

FIG. 1 is an overall configuration diagram of software, which is roughly divided into operation control system software SF1 and learning system software SF2. It should be noted that the operation control system software alone may be used.

The operation control system software SF1 is composed of an operation control program SF14 for directly instructing and controlling the elevator group management control such as the call assignment process and the fractional waiting process of the elevator. An elevator control data table SF11 for the position, direction, car call, etc. of the elevator transmitted from the number control program, a hall call table SF12, an elevator specification table SF13 such as the number of elevators managed, and learning system software SF2 are calculated and output. There are data such as optimum operation method selection parameters and call assignment control parameters.

In the operation control program SF14, the reallocation request detection program SF15 is based on the above input information.
Detects a condition for reassignment and outputs a request for reassignment to the calling program SF16 when the condition is satisfied. That is, the door opening information of the elevator and the door opening extension button information are input from the elevator control data table, it is detected that a predetermined time has elapsed, and a reassignment request command is output to the call assignment control program. The call allocation program SF16 allocates an optimum elevator call based on the estimated arrival time output from the estimated arrival time calculation program SF17 in response to the reallocation request. Other programs SF18 include distributed standby processing.

On the other hand, the learning system software SF12 performs learning of traffic demand, simulation, statistical processing, etc., calculates various parameters necessary for operation control, and outputs them to the operation control system software SF1.

The program described below is a system program that divides the program into a plurality of tasks and performs efficient control, that is, an operating system (O
It shall be managed under S).

Therefore, the program can be started freely from the system timer or from another program.

FIG. 3 shows the operation control system software S of FIG.
The table configuration diagram of F1 is roughly divided into blocks of an elevator control table SF11, a hall call table SF12, and an elevator specification table SF13.

FIG. 4 is a flow chart of the estimated arrival time calculation program SF17 which also calculates the estimated arrival time to an arbitrary floor of the elevator, which becomes the reference data for the waiting time evaluation value calculation. This program is periodically activated, for example, every one second, and calculates the estimated arrival time from the current position of the elevator to any floor for all floors and all elevators.

In FIG. 4, steps E10 and E90 are performed.
Indicates that loop processing is performed for all elevators. In step E20, first, an initial value is set in the work time table T, and the contents thereof are set in the estimated arrival time table of the control table SF11 in FIG.
As the initial value, it is possible to consider how many seconds can be left after the door is opened and closed, and a predetermined time until startup when the elevator is stopped.

Next, go up one floor (step E30),
It is compared whether the floor has become the same as the elevator position (step E40). If they are the same, it means that the estimated arrival time table of one elevator has been calculated, the process jumps to step E90, and the same processing is repeated for other elevators. On the other hand, if "NO" in step E40, the first floor traveling time Tr is added to the time table T (step E50). Then, this time table T is set in the estimated arrival time table (step E60). Next, it is determined whether there is a car call or an assigned hall call, that is, a call to be serviced by the elevator of interest (step E70). If there is, the elevator stops, so the stop time Ta
Is added to the time table (step E80). next,
It jumps to (step E30) and repeats this process about all the floors.

The first floor running time Tr and the single stop time Ta in steps E50 and E80 are given as one of the optimum operation control parameters by the learning software SF2.

FIG. 5 is a flow chart of the call allocation program SF16. This program is activated when a hall call is generated, a reallocation request is detected, or periodically. When a hall call occurs, first, in step H05, the type of hall call is designated. Next, in step H10, the generated hall call is read from the outside. Then, in steps H30 and H70, a loop process is performed for the floor and the direction. In step H40, it is determined whether there is a generated hall call or a call with a reallocation request. If not, the process jumps to step H70 to process all floors and directions. If “YES” in the step H40, in a step H50, a call assignment elevator is selected by a single call assignment algorithm or a plurality of call assignment algorithms (long wait minimum call assignment, wait time distributed minimum call assignment, etc.) to call the optimum elevator. Allocate (Step H6
0).

Then, in step H80, it is determined whether or not all types of hall calls have been processed. For example, general calls, special calls, wheelchair calls (hall calls that call one of a plurality of elevators that can use a wheelchair). Perform processing.

The call assignment algorithm in step H50 can be changed according to the type of hall call.

FIG. 6 shows the reallocation request detection program SF.
15 is a flowchart of 15. This program is activated periodically and loops for all elevators at J10 and J50.

First, at step J20, it is judged whether the door opening time is a predetermined time or longer. If "YES", the process goes to step J30, and if "NO", it is judged whether the opening extension button is operated (step J25). If "YES", the process goes to step J30, and if "NO", the process of the elevator is finished.

Next, in step J30, a reassignment request is output to the hall call already assigned to the elevator, and in step J40, the call assignment program is started to perform reassignment. Next, the procedure goes to step J50 to repeat this process for all elevators.

Incidentally, step J20 and step J25
May be either one.

As described above, the long wait can be prevented in advance by the relatively simple logic.

[0032]

EFFECTS OF THE INVENTION Re-allocating a hall call when the door is continuously opened for a predetermined time or longer predicts in advance that a hall call already assigned to the elevator will be re-allocated. Can be prevented in advance. Also, in the elevator with the opening extension button,
Since the hall call is reassigned when the open extension button is operated, it is possible to prevent long waiting while keeping the overall balance.
