Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an elevator group management control device.

(Prior Art) In recent years, it has become common for group management control devices to control a plurality of elevators to use small computers such as microcomputers.

In such an elevator group management control device, a so-called evaluation formula is used to determine a service car that responds to a generated hall call command.

Although various evaluation formulas are used, the evaluation formula f is usually expressed by the following formula (1).

f-F (MX, KXa+ax)
−(1) However, KXmax −KX, +T.

J MX: Predicted arrival time to assigned hall call KX,: Expected arrival time to assigned call KXmax: Maximum predicted arrival time of already allocated calls It is.

In general, the service index for elevator group management control is the time from the time a hall call occurs until the elevator arrives in response to that hall call (hereinafter referred to as
Conventional group management control devices have short average waiting times (referred to as waiting times), small maximum waiting times, and averaged individual waiting times. When allocating service numbers, an attempt was made to average waiting times by using the maximum value of the predicted arrival time of already allocated calls for each machine as an evaluation element.

In this group management control system, after a hall call is generated, a service elevator number is determined using the above-mentioned evaluation formula (1), and the service elevator number is displayed in the form of a lantern forecast display.

However, in this group management control method, the optimal elevator is selected regardless of the standing position of the elevator user, so the position of the elevator determined as the service number may be far away from the position where the user is standing. In such cases, the elevator user presses the hall call button, the service number is determined based on the evaluation formula, and then the elevator user presses the hall call button. There was a problem in that the elevator users would have to move again to the front of the elevator, which would place an extra burden on the elevator users.

This also means that in recent years, performance such as door opening/closing time has improved significantly, and if a service elevator is waiting on the floor, there are cases where elevator users may miss the service elevator. Ta.

Therefore, by correctly predicting the service elevator number that the user will be assigned in advance and pressing the hall call button near that elevator number, the user can avoid having to move again to the front of the assigned service elevator number. It was hoped that the company would be able to improve its services.

(Problems to be Solved by the Invention) As described above, in the conventional elevator group management control device, the optimal service number is determined regardless of the waiting position of the elevator user, and the service number is determined at any position in the elevator hall. Since it is not possible to predict in advance what the service number will be, there is a problem in that when the user presses the hall call button and the service number is determined, the user has to move to the front of the service number again.

This invention was made in view of these conventional problems, and involves putting multiple elevators into service for multiple service floors, and providing a predetermined response to newly generated hall calls that are common to each elevator. Instead of an elevator group management control method that determines the service elevator number using the evaluation calculation method, the computer always assumes that a hall call will occur even if no hall call actually occurs, and responds to the assumed hall call. By displaying the service car number as a tentatively allocated car number, a person who is planning to use the elevator who comes to the elevator hall can see this display and move to the hall near the door of the car number to which he or she is expected to be allocated if he or she makes a hall call. To provide a group management control device for elevators that can perform a hall call operation and improve service by eliminating the need to move again to the position of the assigned car after the hall call operation. purpose.

[Structure of the Invention (Means for Solving the Problems) This invention involves putting a plurality of elevators into service for a plurality of service floors, and performing predetermined evaluation calculations for hall calls common to each elevator. In the elevator group management control device, the elevator group management control device determines the allocated car that will respond to the hall call and lights up the allocation schedule indicator light installed in the hall on the floor where the hall call occurs. provisional assignment evaluation means for determining the elevator number to be assigned for each floor based on the evaluation calculation for the provisional hall call; and provisional assignment evaluation means installed in the hall of each floor to predict the provisional assignment number determined by the provisional assignment evaluation means. It is equipped with a provisional allocation indicator light.

(Function) In the elevator group management control device of the present invention, a plurality of elevators are put into service for a plurality of service floors, and a predetermined evaluation calculation is performed for a hall call common to each elevator. Determine which car will be assigned to answer the call and have it head to the floor where the hall call occurs, and at the same time, turn on the allocation schedule indicator light installed in the hall on the floor where the hall call occurs, and use the hall to find out which car is answering. inform the person.

In such an elevator group management control device, the tentative assignment evaluation means constantly assumes that a hall call occurs on each floor, and determines the elevator number to be assigned to the tentative hall call for each floor by the above-mentioned evaluation calculation. In order to predict the provisional allocation number determined by this provisional allocation evaluation means, the provisional allocation indicator light installed in the hall of each floor is displayed, and the elevator of which number responds to your own hall call. Before operating the hall call button, the hall users should be able to know what the call button is, so that when they are actually assigned, they will have to rush back to the elevator, which is far away from where they are standing. Eliminate the inconvenience of having to move.

(Example) Hereinafter, embodiments of the present invention will be explained in detail based on the drawings.

The car condition storage circuits 3A to 3D are buffers for storing car positions, driving directions, load signals, and the like. Further, the car call storage circuits 4A to 4D are set when a car call command is registered, and are reset when the car arrives at the floor where the call command is registered.

Further, the hall call assignment storage circuits 5A to 5D are buffers that store an assignment signal and driving direction when an actual hall call assignment is made to the own machine. Further, the hall call reservation assignment storage circuits 6A to 6D are buffers that store reservation assignment signals and driving directions when a tentative assignment, which will be described later, is made to the own car.

7 is a hall condition storage circuit, which stores the data of the hall call storage circuit 1 and the hall call allocation storage circuits 5A to 5A.
This buffer generates a hole condition signal by combining 5D data using a method described later.

Reference numeral 8 is a mask condition storage circuit, and the mask condition storage circuit stores whether the group management control device of this elevator is actually in a group management control operation state, or whether it is in an independent operation state such as inspection operation or operation by an operator. This is a buffer for application data.

Note that the arrow lines connecting the circuits in FIG. 2 indicate a plurality of, for example eight, parallel signal lines. Furthermore, all the registers have the number of bits equivalent to one word of the microcomputer 10.

Next, the operation of the elevator group management control device having the above configuration will be explained.

The wiper select circuit 9 is activated by the sub-address signal 11a output from the output register 11 of the microcomputer 10, and sequentially selects predetermined traffic data from the traffic data group according to the select code that can be output from the output register 11. External information is stored in predetermined storage sections 16 to 19 of the RAM 15 in the microcomputer 10 via the 10 input registers 12 . Then, based on this information, the service machine that responds to the generated hall call command is determined and output from the output register 13.

That is, in FIG. 2, the mask condition table (MCT) stored in the mask condition storage unit 16 in the RAM 15, the car condition table (MCT) stored in the car condition storage unit 17
CCT), the hall condition table (HCT) stored in the hall condition storage section 18, and the car call table (HCT) stored in the car call storage section 19.
KCT) and the predicted arrival time Y of each aircraft stored in the predicted arrival time storage unit 20 as the base EST, the evaluation value calculation unit 22 calculates the evaluation value according to the evaluation formula (1), and then calculates the evaluation value. The evaluation value is stored in the storage unit 21 for each car. Then, even if there is no hall call, the optimal elevator calculation unit 23 periodically assumes that a hall call has occurred at that time even if there is no hall call, and allocates the provisionally assigned car number for the assumed hall call to the hall call number. An evaluation calculation is performed to determine the machine number, and the output register 14 outputs it to the decoding circuit 26.

The data 14g outputted from the output register 14 is decoded by the decoding circuit 26 and stored as a reservation allocated call in the hole call allocation storage circuit 6A to 6D corresponding to the provisionally allocated machine number, and at the same time, as described later, The hall lanterns of the assigned hall numbers will be dimly lit and displayed via a dimmer.

Thereafter, when a new hall call for that floor actually occurs, the service elevator number for that hall call is determined based on the data in the evaluation value storage section 23 that has already been calculated, and is output from the output register 13.

The data output from the output register 13 is decoded by the decoding circuit 25 shown in FIG. The forecast is displayed on the hall lantern.

The data in the hall call allocation storage circuits 5A to 5D is combined with the data in the hall call storage circuit 1 to form the data in the hall condition storage circuit 7, and this data is passed through the wiper selection circuit 9 to the microcomputer 10.
It is stored in the hole condition storage section 18 in the RAM 15 of.

Here, the car condition storage circuits 4A to 4D and the hall condition storage circuit 7 are stored in the car condition storage section 17 and the hall condition storage section 18 in the RAM 15 of the microcomputer 10 via the wiper selection circuit 9. The car condition table (CCT) and the hall condition table (HCT) inputted into the RAM 15 from the car condition table (CCT) have a data structure as shown in FIG.

In the hall condition table HCT, the seventh bit indicates that there is a hall call command when it is "1" and that there is no hall call command when it is "0".

In the car condition table CCT, bit 0 indicates running or stopping; "1" indicates running, and "0" indicates stopping. The 1st and 2nd bits indicate the moving direction of the elevator, and when it is "01" it is the upward direction.
“When it is 10°, it is in the descending direction, and when it is “00”, it is in no direction. Bits 3 to 7 indicate the elevator position,
For example, when it is “00001”, you are on the first floor, and “0001
0" indicates that you are on the 2nd floor, and "01010" indicates that you are on the 10th floor.

Further, the hole condition table (HCT) stored in the hole condition storage section 18 of the RAMI 5 has a data structure as shown in FIG. The 0th to 3rd bits indicate that each elevator is assigned as a set pit for hall call commands, and the 6th bit indicates that the assignment is complete when it is "1".
When it is "O", it indicates that the allocation has not been completed. Also, the 7th bit is “
When the value is 1, there is a hall call command, and when it is 0°, there is no hall call command.

In the above-mentioned elevator group management control system, a hall call is now generated at an arbitrary floor, and the processing operation until a service elevator number is determined in response to the hall call will be explained.

In FIG. 5, the process starts from step Q1, and in step Q2, the RAM initialization subroutine entry address is set. Next, in step Q3, the data of select codes 8 to 11 shown in FIG.
It is stored in the car condition storage section 17 and the car call storage section 19 in M15.

In the following step Q4, a hole index J for scanning the hole state is initialized, and an evaluation function f1, which will be described later, is selected to be used to determine the allocation of a newly generated hole call. Now let's set the hole index J-1 and the downhole call (IO) on the 10th floor.
When checking D), the presence or absence of a hall call command is determined by the “1” or “0” of the 7th bit shown in FIG. 4 of the hall condition table HCT of the hall condition storage unit 18 shown in FIG. The presence or absence of assignment for the hall call command is given by the 6th bit "1" and "02" shown in FIG. Judge the hole condition.

“00”・・・No hall call 1 No assignment “0”
1”・・・Hole call 1 No assignment “11°
・・・・・・There is a hall call and there is 1 quota “10°...”
...With no hole call 1 allocation With the combination of the data of the 6th and 7th bits of the HCT shown in FIG. 4 stored in the hole condition storage section 18 shown in FIG. Perform each process.

(a) In the case of "002," the hall call duration counter (not shown) is set to Tj-0 in step Q6, and the process proceeds to C.

In steps Qll and Q12, the evaluation values of all machines for the hypothetical hall call corresponding to the hall index J are calculated based on evaluation formula (1) and stored in the evaluation value storage section 21 shown in FIG.

In step Q13, the optimum car corresponding to the hole index J is selected based on the value in the evaluation value storage section 21, and the output register 4 shown in FIG.
Output to.

(b) If “10”, T, -Tj in step Q9
Go to D as +1.

(c) If "01", T, -T in step Q8
j+x, the process proceeds to step Q18, where the optimum car is determined based on the evaluation value of each car already calculated in step Q13, and is output to the output register 3 in FIG.

(d) If "11", step Q7 and T.

” Proceed to D as Tj+1.

In this way, the hole index J-1 to J-1
For hall calls on all floors up to 8, the provisionally assigned car number is always determined, and when a hall call actually occurs, the service elevator is determined with the provisionally allocated car number as the actual service car number.

Next, in step Q15, it is checked whether the execution of hole indexes J-1 to J-18 has been completed, and if it has been completed, the process returns to the repeat start point A. However, if it has not finished, step Q
At step 14, the process returns to repeat start point B as J-J+1, and the processing from step Q5 onwards is repeated.

Next, a specific lantern display control device will be explained based on FIG. 6. Note that FIG. 6 shows a lantern control circuit for one of the elevators A to D, and in reality, this lantern control circuit is prepared for each elevator.

Now, suppose that a hall call in the downward direction on the 10th floor is reserved and allocated to car A. In FIG. 2, the reservation allocation of 10D is stored in the hall call reservation allocation storage circuit 6A of car A in FIG. A signal is input to the 10D dimmer 3O-NOD, thereby lighting the 10D lantern 3l-10D dimly and brightly.

Thereafter, when an IOD hall call occurs, car A is normally determined to be the service elevator, and the allocation determination is stored in the hall call allocation storage circuit 5A shown in FIG.
This signal is output as the IOD assignment signal shown in the figure, and this signal causes the IOC dimming device 130. -10D is fully ignited,
10D lantern 3l-10D is brightly lit. In other words, when there is no actual hall call, the IOD lantern 3l-10D lights dimly and brightly to indicate that the machine is provisionally assigned, and then when an actual hall call occurs, it lights brightly to indicate that the actual assignment has been made. It will now display what has happened.

FIG. 7 shows an embodiment in which a service schedule direction display device 32 is provided separately from the hall lanterns of each car in the elevator halls arranged opposite each other as shown in FIG. That is, as shown in FIG. 7, for each set of machines A, B, and C1D arranged on the left and right sides, the left side down direction driver 33DL and the right side down direction driver are determined by the OR value of the temporary assignment signal. 33DR, or by driving the left side up direction driver 33UL and right side up direction driver 33UR, the left side down direction provisional assignment light 34DL and the right side down direction provisional assignment provided inside the service scheduled direction display device 32 are displayed. Light 34DR or left side up temporary assigned light 34UL
, the right side up direction temporary assignment light 34UR is turned on.

In addition, 35AD to 35DD, 35AU to 35DU are normal hall call lantern drivers, and 36AD to 36
DD, 36AU to 36DU are normal hall call schedule display lanterns, and when an actual hall call occurs,
The allocation will be displayed by lighting up the lantern of the allocated machine.

In this way, the planned service direction display device 32 informs the prospective user of which elevator on the left or right side of the elevator hall is scheduled to respond before the hall is called, and the prospective user is displayed. By operating the hall call button on the wall on the side where you are, there is no need to move again after assignment.

It should be noted that the present invention is not limited to the above-described embodiments, and all of the operations described above may be performed by a software program of a microcomputer.

[Effects of the Invention] As described above, according to the present invention, a plurality of elevators are put into service for a plurality of service floors, and a predetermined evaluation calculation method is applied to newly generated hall calls common to each elevator. In an elevator group management control device that determines service elevators using The service forecast for the tentatively assigned car is displayed at all times, so those who come to the elevator hall and plan to use the elevator can see the tentatively assigned forecast display and see if they are tentatively assigned in the direction they want to go. You can make a hall call by operating the hall call button near the elevator of the car you are currently assigned to, and as a result, after the hall call operation, there is no need to move again to the front of the service car where the actual assignment was. This eliminates cases where the door closes during the journey, improving service.
