Abstract

PURPOSE:To make improvements in serviceability to users by allocating an elevator in consideration of the current traffic demand, time and so on whenever a hall call occurs. CONSTITUTION:A command out of an identical hall individual elevator allotment permitting specific floor-time zone setter 2 necessary for a status judging device 2 judging the status of each elevator is transmitted to a group control unit 10 via a line 6. In addition, when a hall call is generated, this status judging device judges whether plural units of elevators are able to be allotted to the same hall or not in consideration of the current traffic demand, time and the like, and if the traffic demand is little and it is the permitted time zone set in advance, by way of example, these plural elevators are allotted to the same hall. In addition, even in the case where the traffic demand is many to some extent, these plural elevators are allottable if it is the hall call of a specific floor. With this constitution, serviceability to users is thus improvable in this way.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a group management control device for elevators, and more particularly to a call assignment system for elevators at an important floor (specific floor) in a building or at a quiet time.

[0002]

2. Description of the Related Art A group management control technique for allocating two or more elevators to hall call registration signals of the same hall of elevators in the same group management group is disclosed in, for example, Japanese Patent Laid-Open No. 55-26103. There was something that was done.
In this conventional technique, a predicted waiting time required for an elevator assigned to a registered hall call to arrive is calculated, and if it is a predetermined value or more, another elevator is additionally assigned to the hall call. .

Another conventional technique is disclosed in Japanese Patent Publication No. 54-37744. This conventional technology is provided in a special hall call registration device for calling an elevator with a small number of passengers, and enables a service in which the degree of congestion of the elevator is more important than the waiting time.

Further, as a prior art relating to a group management control device which takes into consideration the horizontal distance of the hall call registration device and the elevator to be assigned, there is, for example, one disclosed in Japanese Patent Laid-Open No. 4-197969. This prior art preferentially assigns elevators close to registered hall calls.

[0005]

In the first prior art, although the number of elevators to be additionally allocated is variable according to the estimated waiting time at the hall where the call is registered and the traffic demand state, the additional allocation function is In contrast, it does not have a function to reflect the intentions of elevator users.

In the second prior art, a special elevator call registration can be performed by the user's will, but the hall call registration device must be different from a general hall call registration device. In addition, no consideration is given to the transportation capacity, traffic demand, and time of use of the group-controlled elevators in particular, and abuse is a problem especially when the elevators are crowded. In the third conventional technique, the elevators close to the operated hall call registration device can be preferentially assigned while considering the operation efficiency of the group-controlled elevators as a whole. However, it is impossible to call the second and subsequent elevators at the discretion of the elevator user.

An object of the present invention is to solve the above-mentioned problems of the prior art, to individually register a plurality of hall call signals from a plurality of hall call registration devices in the same hall, and to transport in an elevator that is group-managed. It is an object of the present invention to provide an elevator group management control device capable of selecting and executing an appropriate elevator operation method in consideration of capacity, traffic demand, and the intention of elevator users in halls.

[0008]

According to the present invention, the above object is to independently input and output a plurality of hall call registration devices to the same hall and a plurality of hall call registration signals from the hall call registration device. Call signal registration device, a status determination device that determines the status of the elevator that is the target of group management, and the status determination device that displays the traffic demand of the elevator, the current time, and the registered hall call signal. This is achieved by providing a function of determining whether or not the vehicle belongs to a specific floor, and by considering a predicted arrival time of the assigned elevator and a function of considering the degree of congestion in the car when arriving at the hall.

[0009]

When the hall call occurs, the situation determination device considers the current traffic demand, time, etc. to determine whether or not it is possible to allocate a plurality of elevators to the same hall. It is possible to allocate multiple elevators to the same hall within the set permitted hours. This can be used, for example, in an allocation method when the elevator is used quietly, on holidays in a building where the elevator is installed, and the like.

Further, even when the traffic demand is high to some extent, the allocation of a plurality of elevators is permitted if the hall call is on a specific floor set in advance. This can be used for allocation to the lobby floor at check-in at the hotel. In the above two examples, when a call is registered by the hall call registration device, the response light of the call registration device of only the target elevator is turned on.

On the other hand, in cases other than the above, only one elevator is assigned to the same hall as before,
All hall call answering lights will be turned on.

[0012]

FIG. 2 is a software configuration diagram showing an embodiment of the group management control device 10. As a software configuration, a rule table SF for hall call allocation control
It has an operation control program SF10 for directly issuing an instruction to perform call assignment processing and elevator group management control based on the information from 21, and performing group management operation control. Further, as the input information of this program SF10, the machine control device 20-
Elevator control data table SF1 such as elevator position, direction, car call, etc. sent from 22
1, a hall call table SF12, an elevator specification table SF13 such as a group management number of elevators, a rule table, and a parameter table SF21.

Another program is a communication program SF20 with a setting device which gives a control target and a control rule provided externally, and a rule table and a parameter table in which the rule received from the setting tool is recorded as input information of this program. Has SF21.

FIG. 3 is a table configuration diagram of software used in the group management control device 10. Elevator control data table SF11, hall call table
Each table of SF12, elevator specification table SF13, rule table, and parameter table SF21 is composed of each block shown in the figure.

Here, the variables k, m, j, and i respectively indicate the elevator number, the hall call registration device number in the same hall, the hall call direction, and the hall floor.

Further, the programs SF10 and SF20 are divided into a plurality of tasks, and a system program for performing efficient control, that is, an operating system (O
It shall be managed under S).

Therefore, it is possible to freely start this program from the system timer or from another program.

FIG. 4 is an overall processing flowchart of the operation control program.

The operation control program E5 is started after the power is turned on or by restarting. First, in the initial process E10, an initial process such as a clear process for the elevator control data table SF11 and the like is executed.

Next, steps E15 to E50 are repeatedly executed until the power is turned off or a program abnormality occurs, and the group management control is executed.

At step E15, the traffic demand mode calculated at step E35 last time and the current time are input and compared with preset conditions to select an elevator operation method. In step E20, enter the hall call for all floors,
Set and reset the hall call table SF12. It also issues commands to turn on and off the response lamps for hall calls. At step E30, the communication data from the machine control device is stored in the elevator control data table SF11.

At step E35, the mode of the current traffic demand is identified, and the situation determination or hall call assignment rule SF22 is selected accordingly and used for the situation determination at step E15.

In step E40, call assignment processing is performed.

In step E50, guidance services such as the contents of the control currently being performed, elevator services such as arrival guidance, and guidance information such as in-building guidance information from the building management device 11 are performed.

FIG. 5 illustrates step E20 in the overall processing flowchart of FIG. This processing performs hall call processing input / output, and hall call table
Performs setting and resetting to SF12, as well as turning on and off the hall call response lamp. E202, E20
The response lights are turned on based on the judgment of whether or not the elevators can be individually allocated at the portions E3, E204, and E205.
The response lamp is turned off at the portions 06, E207, E208, and E209. Variables (m, j, i) from E202 to E211
Constitutes a triple loop.

FIG. 6 is a detailed flowchart of the hall call allocation process of step E40 of FIG. Step F10 sets the number of iterations of the inner loop of the process of step E40, and the loop variable is n.
In step F20, if there are unallocated hall calls, the hall calls are sorted in descending order of duration. The hall call with the longest duration is set as the assigned hall call. A step F30 decides whether or not there is an elevator among the target elevators under the group management when there is no passenger at the time of arrival at the hall or it is predicted that there will be no passengers. In step F40, the elevator to be assigned to the hall call is selected. In Step F50, Step F
It is determined that the elevator selected in 40 does not satisfy the following conditions. In other words, it is expected that there will be no passengers when arriving at the hall, but there are many car calls currently occurring, and the elevator is such that the expected waiting time of the hall passengers is greater than or equal to a specified value. It is judged whether or not there is a possibility that the call is over the hole in which it is occurring. Elevators that meet the conditions are excluded from allocation. In addition, here, traffic demand of multiple elevators, time,
The hall call may belong to a specific floor, or may be used as a criterion for re-determination of the degree of congestion in the car. In step F60, the finally selected elevator is assigned to the hall call, and notification control such as reservation guidance is performed by the hall display device, the hall voice guidance device, the hall warning device for each machine, and the like. In step F70, the loop variable n is checked to determine the end of this routine.

FIG. 7 is a detailed flow chart of the hall call allocation elevator selection process of step F40 of FIG.

In steps G10 and G110, processing for all units is repeated.

Further, here, when various evaluation value tables are cleared or the best machine is selected in step G120 in order to obtain an evaluation value, that is, the maximum stranger waiting time evaluation value ΦHTM2 (k) and the like. Initial processing such as setting an upper limit value for the required work SWK is also performed.
In step G20, the number k determines whether or not the assignment to the hall call of the corresponding floor i and direction j is permitted. If the new or additional allocation is not permitted, an upper limit is set in the personal waiting time evaluation value ΦHTM1 (k) of that machine in step G100, and the process proceeds to the next machine. If allocation is permitted, step G25
~ G70 obtains each evaluation element of the machine k, and step G
At 120, the one having the smallest total evaluation value Φ (k) is selected as the service machine.

First, in step G25, an overall evaluation value ΦP1 (k) of the person who registered the assigned hall call is obtained. Next, in steps G30 to G70, the stranger overall evaluation value ΦP2 (k) for the hall call and the car call by the passengers in the car (these are collectively called a stranger call) already assigned to the car k is obtained.

First, in step G30, initialization of loop processing for obtaining an evaluation value of another person is performed. This loop processing starts with the assigned hall call floors jn, in and continues until the car floors jk and ik of this car are reached, and the floor calls and hall calls are classified by direction. The loop variable is changed in step G40, and the stranger evaluation value is obtained in step G60. In step G70, it is determined whether or not the processing has been completed for all the strangers in the loop, and if not completed, the processing returns to G40 and proceeds to the next floor. Step G
If it is judged at 110 that all the units are finished, step G120
Calculates the overall evaluation value Φ (k) of all units and selects the unit with the smallest overall evaluation value as the assigned elevator.

FIG. 8 is a flow chart showing an embodiment of the personal evaluation value creation processing in step G25. In this process, the control for preferentially allocating the elevators that are close to the registered hall call registration device to P610 and P
620. In P600, select the allocation rule based on the characteristics such as the floor where the hall call occurred and the traffic demand. In step P610, the waiting time evaluation value ΦHTM1 of the person
(k) is sequentially processed. In Step P620, the proximity electric evaluation value ΦHDTM1 (m, k) based on the horizontal distance between the hall call registration device and the elevator is referred to. In Step P630, the congestion degree ΦWG1 (k) of the person is set in Step P6.
At 40, the predicted passenger riding time evaluation value ΦCTM1 (k) is calculated.

From each of these evaluation factors, the overall evaluation value ΦP1 (k) of the individual for each machine is obtained immediately before the end of step G25 or in step G120. Here, the loop variable k used for the array k is set and updated in steps G10 and G110 of FIG.

In step G60 of FIG. 7, the waiting time evaluation value ΦHTM2 (k) for others, the overall evaluation value ΦP2 (k) for other people, the congestion degree ΦWG2 (k) for other people, and the estimated passenger boarding time evaluation value ΦCT.
Although it is necessary to obtain M2 (k), the near-elevation evaluation value ΦHDTM2 (m, k), etc., it can be obtained in the same manner as the method of calculating the personal evaluation value in step G25.

The final comprehensive evaluation value Φ (k) can be obtained by the following equation.

Φ (k) = ΦHTM1 (k) + k1 * ΦHTM2 (k) + ΦWG1 (k) + k1 * ΦWG2 (k) + ΦCTM (k) + k1 * k2 * ΦCTM (k) + k3 * ΦHDTM1 (m, k) + k1 * k3 * ΦHDTM2 (m, k) Here, k1, k2, and k3 are parameters representing the other person evaluation degree coefficient, the boarding time priority value, and the proximity elevator priority value, respectively.
