2. Description of the Related Art Conventionally, a plurality of elevators are installed side by side,
In an elevator group management system in which an optimal elevator is assigned to a common hall call, if there is a significant demand in the upward direction from the main floor when going to work, non-advanced cars on the main floor will have calls of other floors. By limiting the quota,
The main floor is prevented from degrading the service and the whole is operated efficiently. As a conventional elevator group management device of this type, for example, there is a technique disclosed in Japanese Patent Laid-Open No. 58-22277.

This is a mode in which when the elevator car stands by in a door open state on the standard floor, the evaluation value of the starting car on the standard floor is corrected to limit the allocation to hall calls on other floors, and the non-standard mode. Of the three control modes, the mode that corrects the evaluation value for the starting car and limits the allocation to hall calls on other floors, and the mode that does not correct the evaluation value for both the starting car and the non-starting car , Has at least two types of control modes, and selectively switches these control modes according to traffic demand.

[0004]

SUMMARY OF THE INVENTION In the conventional elevator group management apparatus as described above, when the demand from the main floor is high in the up direction such as when going to work, the down hall call or the basement floor of the main floor is required. The starting car was sometimes assigned to the call.

However, in the case where the starting car has already registered a car call or allocation above the main floor, after servicing the registered car call or allocation, the descending hall of the main floor In order to service a call or a call to a basement floor, a user who made a landing call on the main floor or a call to the basement had to wait a long time.

Therefore, the present invention reduces the waiting time for a call in the downward direction on the main floor or a call on the basement floor even when demand is high in the upward direction from the main floor, such as when working.
An object of the present invention is to provide an elevator group management device that does not deteriorate the service of the main floor in the upward direction.

[0007]

An elevator group management device according to the present invention is an elevator group management control means for allocating a generated hall call to a predetermined elevator from a plurality of elevators using a predetermined evaluation formula. And, in an operating state in which there is a large amount of demand in the upward direction from the main floor, the presence or absence of call registration for judging whether or not the elevator car waiting in the door open state on the main floor is registered and whether other floors are allocated Determination means, a hall call position detection means for detecting whether the newly generated hall call is a call for the basement floor or a down call for the main floor, and the determination result of the call registration presence / absence determination means and the hall call position detection means According to the above, there is provided an assigned car excluding means for excluding the elevator car on the main floor waiting for the door to open from the target of the assignment evaluation calculation.

[0008]

In the elevator group control system of the present invention,
When there is a large amount of demand in the upward direction from the main floor, the call registration presence / absence determining means determines whether or not the elevator car waiting on the main floor with the door open and the call registration and allocation of other floors. The hall call position detecting means detects whether the newly generated hall call is a basement floor call or a main floor down call, and based on the determination results of the call registration presence / absence determining means 5 and the hall call position detecting means, Since the allocation car excluding means excludes the elevator car on the main floor waiting for the door to open from the target of the allocation evaluation calculation, when the operating condition is high from the main floor in the upward direction, For elevator cars waiting in the door open state, for car calls above the main floor, a predetermined elevator car is assigned from the multiple elevators according to a predetermined evaluation formula, and the elevator car goes down the main floor. For directions and hall calls on the basement floor An elevator car that call assignment or cage above the main floor is already registered, irrespective of the starting cage or non starter cage, are excluded from the car assignment.

The interface is connected to the drive control device 11 and converts input / output signal levels. Reference numeral 10 is a group management control unit which is also composed of a microcomputer. Similarly, the CPU 10A, the memory 10C, the interface 10B for transmitting / receiving data to / from the car control unit 9, and the interface connected to the hall button 4 for converting input / output signal levels. It has 10D. Reference numeral 11 is a drive control device for driving the elevator car 1.

Next, the operation of the elevator group supervisory control system of this embodiment will be described with reference to FIGS. 3 is a flowchart showing an operation of setting an allocation candidate car by the elevator group management system according to an embodiment of the present invention, and FIG. 4 is a flowchart showing an operation of excluding allocation targets during the operation of FIG. A program for performing each operation in FIG. 4 is stored in the memory 10C in FIG. The allocation candidate car setting program shown in FIG. 3 is activated each time the hall button is operated.

In the figure, it is determined in step S1 whether the hall call for which the hall button 4 has been operated is a new hall call. If the hall call has already been registered, the process proceeds to step S6. , The allocation candidate car is cleared to 0, and this processing ends. In the case of a new hall call, it is determined in step S2 whether the floor on which the hall button 4 is operated is a floor below the main floor or the down direction of the main floor, and the hall button 4 is operated. If the determined floor is above the main floor or in the up direction, the process proceeds to step S7 and all elevator cars 1
Is set in the allocation candidate car, and this processing ends. On the other hand, if the floor on which the hall button 4 is operated is the floor below the main floor or the down direction of the main floor, it is determined in step S3 whether or not the vehicle is driving at work, and the vehicle is not driving at work. In this case, the process proceeds to step S7, all elevator cars 1 are set as the allocation candidate cars, and this process ends. When driving at work, the number of cars excluded from allocation or the number of cars excluded from allocation is set by the allocation exclusion process (see FIG. 4) in step S4, and the number of exclusion-excluded cars set by the above allocation exclusion process in step S5. And the number of elevator cars 1 installed are the same, and if the number of excluded cars set in the allocation exclusion process and the number of installed elevator cars 1 are different, the process proceeds to step S8 and the allocation exclusion process is performed. The elevator car 1 other than the allocation-excluded car set in step 1 is set as the allocation candidate car, and this process ends. Also,
If the number of cars excluded from allocation set in the allocation exclusion process and the number of installed elevator cars 1 are the same, step S
In step 7, all elevator cars 1 are set as allocation candidate cars, and this process ends.

Here, the operation for excluding the allocation target in step S4 will be described. FIG. 4 is a flowchart showing the allocation object exclusion processing operation in operation in FIG. 3, which is an allocation exclusion program for a plurality of elevator cars 1 waiting in the door open state on the main floor.

In the figure, in step S11, the car number of interest, the number of cars excluded from allocation, and the cars excluded from allocation are cleared to 0,
The car number of interest is the elevator car 1 in step S12.
It is determined whether the number is smaller than the installed number of. If the car number of the car of interest is equal to or greater than the number of elevator cars 1 installed, the process ends. On the other hand, when the car number of the car of interest is smaller than the number of installed elevator cars 1, it is determined in step S13 whether the car position of the car of interest is in the upward direction of the main floor and the car state of the car of interest is waiting in the door open state. If the car of interest is in the upward direction of the main floor and the car of the car of interest is in the door open state and is not on standby, the car number of interest is incremented in step S17, and the process returns to step S12. .. Further, when the car position of the car of interest is in the ascending direction of the main floor and the car of the car of interest is on standby with the car open, it is determined in step S14 whether or not there is an assignment or car call registration to the car of interest. If there is no car assigned or car call registered to the car of interest, the car number of the car of interest is incremented in step S17, and the process returns to step S12. If the car of interest has an allocation or car call registration, the car of interest is set as an exclusion car in step S15, the number of cars excluded from allocation is incremented in step S16, and the car number of the car of interest is incremented in step S17. Then, the process returns to step S12. In this way, the process is repeated until the car of interest reaches the number of cars installed or more.

As described above, the elevator group supervisory control apparatus of the present embodiment assigns the generated hall call to the most appropriate elevator from a plurality of elevators using a predetermined evaluation formula, Elevator group management control means 3 that appropriately manages the elevator car 1 that is the allocation evaluation calculation target from the assigned car excluding means 6 as group management information, and there is a large demand in the upward direction from the main floor such as when driving at work. In the operating state, the call registration presence / absence determining means 5 for determining the car call registration of the elevator car 1 waiting in the door open state on the main floor and the presence / absence of allocation of another floor, and a newly generated hall call Is a call to the basement floor or a call to the downstairs floor, the hall call position detecting means 7 for performing the processing of steps S1 and S2 in FIG. 3, the call registration presence / absence determining means 5 and The assigned car excluding means 6 for performing the processes of steps S4 to S8 of FIG. 3 for excluding the elevator car 1 on the main floor waiting for the door to open from the target of the assignment evaluation calculation based on the determination result of the place call position detection means 7. Is equipped with.

That is, in the elevator group management system of this embodiment, the call registration presence / absence determining means 5 is provided on the main floor during operation such as at the time of work when there is a large demand in the upward direction from the main floor. The car call registration of the elevator car 1 waiting in the door open state and the presence / absence of allocation of another floor are determined, and the hall call position detecting means 7 is provided.
It is detected whether the hall call newly generated in 1 is a basement floor call or a main floor down call, and this call registration presence / absence determining means 5 is detected.
According to the determination result of the hall call position detecting means 7, the assigned car excluding means 6 excludes the elevator car 1 on the main floor waiting for the door open from the target of the assignment evaluation calculation.

Therefore, the elevator car 1 waiting in the door open state on the main floor at the time of operation at the time of work is a plurality of elevator cars according to a predetermined evaluation formula for a car call above the main floor. A predetermined elevator car 1 is assigned from the above, and for the landing call on the main floor in the down direction and on the basement floor, the elevator car 1 that is assigned above the main floor or the car call is already registered is , Regardless of whether it is a starting car or a non-starting car, it is excluded from the target of car allocation.
That is, when the main floor is in an operating state in which there is a large amount of demand in the up direction, in response to a call for a down hall on the main floor or a call for the basement floor,
The unassigned elevator cars 1 other than the already assigned elevator car 1 are assigned. For this reason, when driving to work, the advance car above the main floor with a registered car call or quota will service the registered car call or quota, and the main floor downhill For calls and calls on the basement floor, a car call above the main floor or an elevator car 1 other than the elevator car 1 for which the allocation is already registered is assigned and serviced. Therefore, when there is significant demand in the upward direction from the main floor, such as when driving at work, as in the conventional case, the advance car with a car call or allocation above the main floor is already registered on the main floor. Since it is not assigned to a down hall call or a basement floor call, it is not necessary for a user who has made a down hall call or a basement floor call on the main floor to wait for a long time. As a result, when going to work, etc., the waiting time for a call in the downward direction on the main floor or a call on the basement floor decreases,
Moreover, the service in the upward direction on the main floor does not deteriorate.
