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 an elevator call assignment system at an important floor (specific floor) in a building or when the building is closed.

[0002]

2. Description of the Related Art A group management control technique for allocating two or more elevators to a hall call registration signal of the same hall of an elevator in the same group management group is described in, for example, Japanese Patent Application Laid-Open No. 55-26103. Something was done.
This prior art calculates an estimated waiting time required for an elevator assigned to a registered hall call to arrive, and if it is equal to or greater than a predetermined value, additionally allocates another elevator to the hall call. .

[0003] Another conventional technique is disclosed in, for example, Japanese Patent Publication No. 54-37744. This prior art is provided in a special hall call registration device for bringing in an elevator with a small number of passengers, and enables a service in which the degree of crowding 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 between a hall call registration device and an elevator to be allocated, there is one disclosed in, for example, Japanese Patent Application Laid-Open No. 4-197969. This prior art preferentially assigns an elevator close to a registered hall call.

[0005]

According to the first prior art, the number of additional elevators to be allocated is variable according to the estimated waiting time at the hall where the call is registered and the traffic demand state. On the other hand, it has no function to reflect the will of the elevator user.

[0006] In the second prior art, a special elevator call registration can be performed by a user's will. However, the hall call registration device needs to be different from a general hall call registration device. In addition, no consideration is given to the transport capacity, traffic demand, and usage time zone of the entire elevators that are group-managed, and abuse during elevator congestion becomes a problem, in particular. In the third prior art, an elevator close to the operated hall call registration device can be preferentially assigned while taking into consideration the operating efficiency of the entire group of elevators. Is possible, but it is impossible to call in the second and subsequent elevators at the discretion of the elevator user.

[0007] It is an object of the present invention to improve serviceability to users.
It is to provide an improved elevator control device.

[0008]

SUMMARY OF THE INVENTION The present invention is directed to a plurality of floors.
It is installed on the same floor with multiple elevators
Multiple hall call devices and registered hall calls
Select the elevator to service and call the hall
In the elevator control device which is configured to assign
One elevator is assigned to the hall call on the first floor
Operating on the same floor as the first hall call allocation means.
For registering different hall calls separately
And these multiple distinctly registered hall calls

Hitting means, and these two hall call allocating means.
It is characterized by using properly.

[0009]

In a preferred embodiment of the present invention, when a hall call occurs, the situation judgment device determines whether or not it is possible to allocate a plurality of elevators to the same hall in consideration of the current traffic demand and time. Judgment, for example, if the traffic demand is small and the preset permission time zone,
A plurality of elevators can be assigned to the same hall. This can be used, for example, in an assignment method when the use of an elevator is idle or on a holiday in a building where the elevator is installed.

[0010] In addition, if the hall call for a specific floor traffic demand has been set in advance even if to some extent many, Ru is also possible to allow the assignment of a plurality of elevator. This can be used to assign to the lobby floor at hotel check-in. In the above two examples, when a call is registered by the hall call registration device, it is desirable to turn on the answering light of the call registration device only for the target elevator.
No.

[0011] On the other hand, in the case other than those listed above, decided to assign the elevator of only one is conventionally the same hall, in one of the hall call of the operation of the first floor, the same of the same floor
All response lights in the direction will be turned on.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

Further, the command from the specific hall setting permission floor 2 for the same hall individual elevator allocation permission required for the situation determination device for determining the status of the elevator is transmitted to the group management control device 10 via the line 6.

FIG. 2 is a software configuration diagram showing an embodiment of the group management control device 10. Rule table SF for hall call allocation control as software configuration
An operation control program SF10 for directly instructing the call assignment process and the elevator group management control based on the information from 21 and controlling the group management operation is provided. Further, as input information of the program SF10, the machine control devices 20 to
Elevator control data table SF1 such as the position, direction, car call, etc. of the elevator transmitted from 22
1, a hall call table SF12, an elevator specification table SF13 such as an elevator group management number, a rule table, and a parameter table SF21.

Another program is a communication program SF20 for communication with a setting device for providing a control target and a control rule provided externally. The rule table and the parameter table record the rules received from the setting tool as input information of the 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.

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

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 / O)
It is assumed that it is managed under S).

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

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 a restart. First, an initial process such as a clear process of the elevator control data table SF11 and the like is executed in an initial process E10.

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

In step E15, the traffic demand mode and the current time calculated in the previous step E35 are input and compared with preset conditions to select an elevator operating method. In step E20, hall calls for all floors are input,
Sets and resets the hall call table SF12. In addition, a command to turn on and off the answering lamp in response to the hall call is issued. In step E30, communication data from the car controller is stored in the elevator control data table SF11.

In step E35, the mode of the current traffic demand is identified, and the state determination and the hall call assignment rule SF22 are selected and used for the state determination in step E15 accordingly.

At step E40, a call assignment process is performed.

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

FIG. 5 illustrates step E20 in the overall processing flowchart of FIG. This process performs hall call processing input / output and the hall call table
It sets and resets the SF12 and turns on and off the hall call answering lamp. E202, E20
The response light is turned on based on the judgment on whether the elevator can be individually assigned in the portions E3, E204 and E205, and E2
The response lights are turned off at the portions 06, E207, E208, and E209. Variables (m, j, i) from E202 to E211
Form a triple loop.

FIG. 6 is a detailed flowchart of the hall call assignment process in step E40 of FIG. Step F10 sets the number of repetitions of the inner loop of the process of step E40, and sets the loop variable to n.
In step F20, if there are unassigned hall calls, the hall calls are sorted in descending order of the hall call duration. The one with the largest hall call duration is set as the assigned hall call. In step F30, it is determined whether or not there are any passengers that are expected to be absent or not at the time of arrival at the hall among the elevators subject to group management. In step F40, an elevator assigned to the hall call is selected. In step F50, step F
It is determined that the elevator selected at 40 does not satisfy the following conditions. That is, it is expected that there will be no passengers when arriving at the hall.However, if there are many car calls and the expected waiting time for the hall passengers is longer than a predetermined value, or if the preceding position of the elevator is It is determined whether or not there is a possibility that the vehicle is over the hall where the call is generated. Elevators that meet the conditions are excluded from assignment targets. Here, the traffic demand of multiple elevators, time,
Whether the hall call belongs to the specific floor or the degree of congestion in the car may be used as a reference for re-determination. In step F60, the elevator finally selected is assigned to the hall call, and information such as reservation guidance is controlled by a hall display device, a hall voice guidance device, a hall alarm for each car, and the like. In step F70, the loop variable n is checked, and the end of this routine is determined.

FIG. 7 is a detailed flowchart of the hall call assignment elevator selection process in step F40 of FIG.

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

Here, in order to obtain the evaluation value, that is, the maximum other person waiting time evaluation value ΦHTM2 (k), etc., when various evaluation value tables are cleared or the best machine is selected in step G120. Initial processing such as setting an upper limit value to a required work SWK is also performed.
In step G20, the car k determines whether or not the assignment to the hall call of the corresponding floor i and direction j is permitted. If it is a new or additional allocation-disabled car, in step G100, an upper limit is set to the personal waiting time evaluation value ΦHTM1 (k) of the car, and the process proceeds to the next car. If the assignment is permitted, step G25
To G70, each evaluation element of the unit k is obtained.
At step 120, the one with the smallest overall evaluation value Φ (k) is selected as the service unit.

First, in step G25, the total evaluation value ΦP1 (k) of the person who has registered the hall call to be allocated is obtained. Next, in steps G30 to G70, the other person's overall evaluation value ΦP2 (k) for the hall call already assigned to the car k and the car call by the passengers in the car (collectively referred to as another person's call) is obtained.

First, in step G30, initialization of a loop process for obtaining an evaluation value of another person is performed. This loop processing is for a hall call for each floor and direction during a round of the car until it reaches the car floor jk, ik of this car, starting from the hall floor jn, in to be assigned. At step G40, the loop variable is changed, and at step G60, the other person's evaluation value is obtained. In step G70, it is determined whether or not the processing has been completed for all the other calls in the loop. If not, the process returns to G40 and proceeds to the next floor. Step G
If it is determined at 110 that all units have been completed, step G120
Calculates the total evaluation value Φ (k) of all the units, and selects the unit having the smallest total evaluation value as the assigned elevator.

FIG. 8 is a flowchart showing one embodiment of the personal evaluation value creation processing in step G25. In this processing, the control for preferentially assigning the elevator in proximity to the registered hall call registration device is performed in P610 and P610.
620. At P600, select the allocation rule based on the characteristics of the floor where the hall call occurred and the traffic demand. In step P610, the person's waiting time evaluation value ΦHTM1
(k) is sequentially processed. In step P620, the near-elevation 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 personal congestion degree ΦWG1 (k) is calculated in Step P6.
At 40, the person's predicted riding time evaluation value ΦCTM1 (k) is obtained.

A total evaluation value .PHI.P1 (k) of the person for each car is obtained from these evaluation factors 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 in FIG.

In step G60 of FIG. 7, the other person's waiting time evaluation value ΦHTM2 (k), the other person's comprehensive evaluation value ΦP2 (k), the other person congestion degree ΦWG2 (k), the other person's predicted riding time evaluation value ΦCT
M2 (k), the near-elevation evaluation value ΦHDTM2 (m, k), and the like need to be obtained, but can be obtained in the same manner as the method of calculating the principal evaluation value in step G25.

The final overall 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 others evaluation degree coefficient, the riding time priority value, and the proximity elevator priority value, respectively.
