Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for group management of elevators operated by destination buttons installed at a landing.

[Conventional technology]

Normally, in an elevator, a hall call is registered using an up or down button installed at the hall, and a car is summoned by this hall call. When the car arrives, passengers board the car and press the destination button inside the car to register the car call.
The car completes a series of services in response to this car call.

Recently, by installing a control panel with a destination button at the landing and registering the destination call directly at the landing, the operability of the button has been improved and the management Btit system allows the destination floor to be known before the car responds to the landing. The one that aims to improve the
For example, Jikko 53-. It is shown in Japanese Patent No. 40843.

Fig. 13 is a diagram showing the landing on the second floor of the conventional group control elevator, in which r and Y are the landing doors of i1 and 2, respectively, and αO is the destination of the 1st floor and the 3rd to 8th floors. Button (LA)
, (3A) to (8A) are arranged, and the landing operation panel registers the destination call for each S in both the first and second cars. (IIK) and (12K) are the upper and lower seats of the first car. The arrival warning lights, (IIY) and (12Y) are also the arrival warning lights of Unit 2, and (13x) and (13Y) are the arrival forecast lights of Units 1 and 2.
This is a destination floor indicator that displays the destination floor of the car.

In other words, at the landing on the 2nd floor, press the destination button (5A) for the 5th to 8th floors.
) to (8A) are pressed. Now, the 2nd floor landing call is registered and at the same time the destination buttons (5A) - (
A destination call according to 8A) is assigned to each car. Various types of this allocation method have been proposed, and for example, as shown in Japanese Patent Publication No. 58-32154, there is a method in which cars are allocated based on allocation evaluation values. That is, the landings to be assigned to the cars are selected and provisionally allocated to each car, the predicted service times for the landings already allocated to each car and the landings temporarily allocated above are calculated, and the service status is evaluated for these. The evaluation value is calculated and the car allocation is performed based on this value (the calculation of the evaluation value will be described later). As a result, 6
Assuming that the destination calls for the 5th and 8th floors are assigned to Unit 1, and the destination calls for the 5th and 7th floors are assigned to Unit 2,
These destination floors are the destination floor indicators (13x) and (13x), respectively.
Y).

Now, after the first and second cars arrive at the a2 floor, they will head to their respective assigned floors.

[Problem that the invention seeks to solve]

In the conventional elevator group control device as described above, when many destination calls are registered for the same direction on the same floor, multiple cars are assigned when one power car cannot handle the calls. It will be done. At this time, the destination floor will be displayed for each car, and passengers waiting at the landing can tell which car they should board by using the destination floor display (13K) or (13Y).
However, with the display shown in Figure 13, if there are a large number of cars and floors, it is difficult to find the car, and there is a problem in that waiting passengers move back and forth around the boarding area.

This invention was made to solve the above-mentioned problem, and even when many destination calls are registered for the same direction on the same floor, it is possible for passengers waiting at the landing to easily find the car they should board. The purpose of the present invention is to provide a group management device for elevators.

[Means for solving problems]

The elevator group management device according to the present invention, when allocating a destination call from a destination button provided at a landing to a car based on an allocation evaluation value, ensures that the scheduled stop floors of the allocated car □ overlap with each other of the allocated cars. This system is provided with a floor polymerization evaluation means that calculates a floor polymerization evaluation value representing , and introduces this value into the above-mentioned assigned evaluation first shift.

[Effect]

In this invention, by introducing the above-mentioned floor overlap evaluation value into the assigned evaluation value), the chances of the destination floors displayed at the landing being overlapped with each other in the assigned cars are reduced, and each destination floor is displayed consecutively. Increase the degree.

〔Example〕

FIG. 1 is an overall configuration diagram of an embodiment of an elevator group management device according to the present invention. As is clear from FIG. 1, in this embodiment, when the destination button A (destination buttons (LA), (3A) to (8A), etc. are collectively referred to as A) installed at the landing is pressed, Destination call registration means α9
The destination call allocation means αQ calculates the allocation evaluation value for each car's destination call, and based on this, the destination call is allocated to one of the cars. The assigned car is driven and controlled by the drive control device αη, and is caused to respond to the floor indicated by the destination call. At the same time, this destination floor is displayed on a destination floor indicator (to) at the landing (in this embodiment, a destination floor indicator using an indicator light is used). On the other hand, in the α frame of the floor overlap evaluation method, a floor overlap evaluation value indicating that the floors on which the assigned cars are scheduled to stop are overlapped with each other for each assigned car is calculated, this is introduced into the above allocation evaluation value, and the destination Floor display 1 (1
The destination floors displayed in No. 3 are configured to reduce the chance that the assigned cars overlap with each other.

FIG. 2 is a block circuit diagram of the embodiment of FIG. 1.

In the figure, the cage control microcomputer (only one unit is shown) is composed of a microcomputer (hereinafter referred to as microcomputer).
For example, it has a configuration similar to that shown in Japanese Patent Application Laid-Open No. 51-53354.

, a transmission device (21C) and a variable IIL device (21D) for converting the input/output level for the destination button A at the landing.

FIG. 3 is a front view of the second floor landing of the two-passenger car according to the embodiment of FIG. 1.

In the figure, x, Y, (LA), (3A) ~ (8A
), α0 are the same as in FIG. 2 is the landing door of No. 3 car, and (13X) to (13Z) are the destination floor indicators of No. 1 to No. 38 cars.

Figure 4 shows the destination call registration floors yo registered for each hall operation panel on each floor, and vertically shows the installation floor t (=x,
2.3...8) and the destination registration floor j (=1, 2.3...8) of floor 1 where the hall operation panel is installed in the horizontal direction. For example, if H1j=rlj, it indicates that the destination call for the jth floor row of the first floor landing is registered.

Figure 5 shows the allocation status of each floor to the destination call for each car, so W1 to W3 indicate the assigned floors for cars 1 to 3, respectively.For example, if W, ij = "1", , indicates that Car No. 1 is assigned to the J floor destination call of the 1st floor landing.

The destination call registration floor H and the assigned floors W1 to W3 are arranged and set in the RAM of the storage device (21B) of the group management microcomputer 2°C.

FIG. 6 shows an example of the car allocation status and destination floor display. For example, the destination calls for the 1st, 4th, 6th, and 8th floors on the 2nd floor are the 1st floor destination call, the 4th and 6th floor destination calls, and the 8th floor destination calls, respectively. is 3
This indicates that it is assigned to the machine number. and,
The destination floor indicator (13M) on the 2nd floor shows the 1st floor, the destination floor indicator (13Y) shows the 4th to 6th floors, and the destination floor indicator (13Z) shows the 1st floor.
) respectively display the 7th and 8th floors. here,
Although the 5th floor is not assigned to 28 aircraft, it is displayed in this way because it is easier for customers to wait by displaying the 4th to 6th floors consecutively. In addition, in order to encourage waiting customers to register a destination call, it is also possible to display floors other than the assigned floor or change the display format. In addition, in the 38 aircraft, there is only the 8th floor assigned destination call on the 2nd floor,
Since the destination call for the 8th floor is assigned to the 7th floor in front of the 2nd floor, the 7th floor is also displayed. In this example, we will show an example in which the destination floors are displayed including all the floors scheduled to stop on the front floor, but the floors scheduled to stop other than the registered destination call on the floor where the landing operation panel is installed are not displayed. You can also do this. If the destination floors are displayed consecutively in this way, it will be easier to see, but in order to do this, when assigning destination calls, the assigned destination calls for each car should not overlap each other, as shown in assigned floors W1 to W3. , and it is considered best to allocate them consecutively.

Also, considering the effectiveness of group management, it is important to ensure that the destination floors of each car do not overlap with each other and that continuous VC is provided, including not only the destination call on that floor, but also the scheduled stop floor on the previous floor. A better allocation would be For this reason, the present invention attempts to evaluate the overlapping of assigned destination calls for each car as a negative factor and introduce it into the assignment evaluation value.

Next, the operation of this embodiment will be explained with reference to FIGS. 7 to 10. Figure 7 shows the storage device (
21B), FIG. 8 shows a subprogram thereof, and FIG. 9 shows details of one processing step in FIG. 8.

Figure 10 shows the storage device (20B) of the car control microcomputer (1).
) is a flowchart of operations performed by a program stored in .

When the destination button A is pressed at each floor landing, a destination call registration operation is performed by the program stored in the ROM. However, since this is a well-known operation in elevator operation, a detailed explanation using a flowchart of the operation will be omitted.

Now, in step G1J of Fig. 7, set the scanning installation floor 1° to zero,
Set the scanning destination floor j to zero in step (a), set the scanning installation floor 1 to 1+1 in step 5 (end) of initializing the scanning installation floor and scanning destination floor, and set the scanning destination floor j in step (b). As j+1, the scanning installation floor and scanning destination floor are updated one floor at a time. In step (to), check whether the call for the 50th floor of the 1st floor landing is registered. It is judged whether jo is "1" or not, and if it is registered, in the procedure (to) it is determined whether these destination floor calls are unassigned by -1゜j, Wij and W.
0 2o where both 31゜jo are “0”
.

Judge whether or not. That is, it is determined whether or not a call for the 50th floor of the 1st floor landing is assigned, and if it is not assigned, the subprogram WA shown in FIG. 8 is executed in step (b).
Execute Rl to select whether to divide the call from the 1st floor to the 50th floor. If the call for the 50th floor of the 1st floor landing is not registered in step (To), and if a car has already been assigned in step (To), do not execute step (B) and proceed to step (To). fly to In step (to), it is determined whether scanning of the destination floor has been completed, and if it has not been completed, the process returns to step (b)) to continue scanning. When the scanning of the destination floor is completed, it is determined in the procedure screen whether the scanning of the installation floor has been completed, and if it is not completed, the process returns to step (to) and continues scanning.

Next, in the step (37A) of FIG. 8, the 8 assigned cars K are set to zero, the assigned car memory data is cleared, and the assigned car memory data is cleared, and the assigned car memory data is cleared.
), set the maximum value (the smaller the evaluation value, the better) in the memory that temporarily stores the result of the evaluation value E.

In step (37C), the scan number is set to zero to initialize the scan number, and in step (37D), the scan number is set to +1 and the scan number is updated one by one. In step (37E), a floor overlap evaluation value e(ko, i., jo, i) indicating that the scheduled stopping floors of the assigned cars overlap with each other is calculated. This subprogram is shown in FIG. 9, and this floor polymerization evaluation 1e (ko, i., jo, 1) continuously captures the 1° floor of 0 in the car and the floor scheduled to stop in front of it. This shows the overlap with the planned stopping floor of other cracking corners.

Next, an allocation evaluation value is calculated in step (37F).

This is calculated by adding the waiting time for all destination calls at each landing (including those not assigned to car 0) when the above-mentioned allocation is made to car 0, and the service time after boarding. , furthermore, the floor polymerization evaluation value θ(k, i , j, t
) will be introduced for comprehensive evaluation. Here, R
kij is the expected arrival time required for car K to arrive at the 1st floor, Tij is the time from when the call for floor j is registered on the 1st floor - 1, that is, the duration time, and 5kij is the expected arrival time for car k to arrive at the j floor from the 1st floor. Wkij is each element of the assigned floor shown in Fig. 5, and when car k is assigned to a call bound for floor j on the 1st floor, It becomes 1, and becomes 0 when it is not allocated.

In this way, the assigned evaluation value Ek0 is Sat. Service evaluation value for the call to the 50th floor (Rk0 courtesy j. 10 Ti.

j0+5ko1ojo'), each destination call that has already been registered and assigned (as for the assigned destination calls, waiting time and service time may become longer by assigning new calls to the 10th floor and the j floor) ), (37
The floor polymerization evaluation value e (kioj, i) obtained in K) is α
By weighting it by a predetermined number (predetermined number) and adding all the floor overlap evaluation values, it is evaluated as bad when the 10th floor and the floor scheduled to stop in front of it overlap with other cars.

Note that the means for calculating Rkij and Tij are calculated in the same manner as in a known group control device using normal elevator up and down calls, and Skj is also calculated in exactly the same manner as Rkij. Therefore, although it is not shown in the diagram, the destination floor on the 1st floor is known before the arrival on the 1st floor, so not only can the destination be stopped at the installation floor by being assigned as the stop floor, but also the destination can be stopped by calling the destination from the installation floor. Next, in step (37G), it is checked whether the allocation evaluation [xko] in step (37F) is smaller than the best evaluation value E0 so far, and the best evaluation f If it is smaller than E0, hand +1i!
At (37H), the car k is made the new selected car k, and the best evaluation value E0 is also updated to Eiko. If the allocation evaluation f value Ek0 is not smaller than the best evaluation value E0 in step (37G), step (37H) is not executed. Hand l1li (37
In d), it is determined whether scanning has been completed for all machines, and if it has not been completed, the process returns to step (3?D). When the scanning is completed, the best car k so far is set as the allocated car in step (37J). ! Ta, Wkoi. After setting Jo to 1, the operation of calculating the floor polymerization evaluation value using the subprogram shown in FIG. 9 will be explained.

This means that the scanning number is set to 0, and if the installation method is 1゜, the destination floor j
This is to check the overlap with other units for the destination floor in the installation method i (floors from the 1st to the 8th floor) when the designation is assigned, and if there is overlap, the floor overlap evaluation value e (koi
ojoi).

Here, the overlap with other cars on the destination floor refers to the overlap of service display sections of each car, which will be described later.

The service display section is set by considering the scheduled stopping floor of each car as a continuous scheduled stopping floor even if there is no plan to stop on the way.For example, if the actual scheduled stopping floor of a certain car is 4. , the 5th floor, and the 8th floor, all of the 4th to 8th floors are considered to be the destination floors.

Furthermore, when the planned stop floors are defined in detail, the assigned floors W1 to W
3, the set floor to which at least one destination call is assigned, all assigned destination call floors, and the call floors that are currently already registered in the car. However, floors that have been serviced by that car or other cars before the car arrives at installation method 1 and are no longer required to be serviced after departing from the 1st floor are excluded from the floors where the car is scheduled to stop on the 1st floor. be done.

Further, the scheduled stop floor needs to be determined by taking into consideration the service direction of the car, but this is easily inferred from conventional elevator technology, so the description will be omitted.

In this way, in FIG. 9, the overlap of the service display sections of each car is determined for each floor 1. In this case, the floor polymerization evaluation value e(kol.jol) is 0, since there are 3 cars.
The eyes will be either 1 or 2.

Now, in Step II (37Kl), the scanning setting technique 1 is set to zero to initialize the scanning setting floor, and in step (37E2), the scanning setting technique 1 is set to 1+1 and the scanning setting technique 1 is updated one floor at a time. In the procedure (37 to 3), the service display sections J, to J2 with the setting method of 0 in the scanning number are calculated. Here, Jl
is the lowest floor in the above section, and J2 is also the highest floor. In this case, both the 1° floor and the -0 floor are included as the scheduled stop floors.
Calculate the service display section for other car installation techniques 1. In this case, the floor type joint evaluation l1llIi@θ(
kol. , joi) to zero. Procedure (37E
In step 6), a car other than 0 is scanned for the scanning number, and if the service display section overlaps with that for the scanning number 0, 1 is added to the floor overlap evaluation cylinder e (koi.jol). Hand 1
In step 11i (37 to 7), it is determined whether the installation technique scan is completed, and if it is not completed, the process returns to step (37 to 2).

Figure 1Q shows the destination display control operation program for the destination floor indicators (13K) to (13Z). Judging from the destination call registered as a call, it is determined whether each destination floor display [alpha] at each landing is to be turned on or not, and the result is output to the destination floor display α3. That is, in each installation method, if that floor is a planned stop floor, the service display section is determined for that floor, and all indicator lights corresponding to the destination floor within that section are turned on.

Perform the initial settings for the scanning installation technique in step (6), and then proceed to step (6).
The scanning installation method is updated one floor at a time. In step III (to), check whether the 1st floor is the scheduled stop floor or not by assigning floor W1 (or W2.
3) Determine whether there is a way to install a destination call on the floor where the destination call is assigned, or whether it is the floor of the assigned destination call or the floor of the destination call that has already been registered in the car. Here, as explained in FIG. 6, it is also possible to judge whether the floor is the planned stop or not only by determining whether there is an installation method that allows the destination call to be assigned.

The service display sections J1 to J2 for the installation technique i are calculated in the same manner as explained in FIG. 9 in the procedure (Foundation). In step θ), the scanning destination floor is initialized (b), and in step θ, the scanning destination floor is updated one floor at a time. In step 0η, it is determined whether or not to display the bound for the jth floor of the 1st floor based on whether J1≦j≦J2, that is, whether the jth floor is included in the service display section J1-J2.5 It is determined that the display should be displayed. And hand l'l@(
Step 7) Turn on the indicator light for floor J on the 1st floor. If it is determined that the display is not to be displayed, turn off the J-bound indicator light on the 1st floor in step (to).In step 5 (to), it is determined whether the destination floor scanning has been completed, and if it has not been completed, the process proceeds to step O. return. If it has been completed, it is determined in step (51) whether the scanning of the installation floor has been completed, and if it has not been completed, the process returns to step (c). In addition, the procedure □□□
If it is determined that the 1st floor is not the scheduled stop floor, step (52)
), all the indicator lights on the 1st floor go out and jump to step (51).

In this way, the destination floor is displayed on the destination floor indicators (13K) to (13Y), for example, as shown in Figure 6, so that continuous display is provided without overlapping each unit. . Therefore, waiting customers can easily find their own car.

11 and 12 show other embodiments of the invention,
FIG. 11 is a front view of the destination floor display (13x), and FIG. 12 is a destination display control operation program, which corresponds to FIG. 10. Here, the destination floor is displayed on the destination floor display (13M) in a format from the 5th floor to the 52nd floor.

Initial setting of the scanning installation floor is carried out in Hand Ill (61), and the scanning installation floor is updated one floor at a time in Hand Ill (62). In step (63), it is determined whether the first floor is the planned stop floor, and if it is, the service display sections J1 to J2 on the installation floor 1 are calculated in step II (64). In step (65), the lowest floor J1 is displayed on the left indicator light, and the highest floor J2 is displayed on the right indicator light. In step (66), it is determined whether the scanning of the installation floor has been completed, and if it has not been completed, a thousand one (one hundred (62)
Return to If it is determined in step (63) that the first floor is not the planned stop floor, the indicator light for the first floor is turned off in step (67), and the process jumps to step (66).

In each of the embodiments described above, a destination floor indicator is used as the destination floor indicator, but a voice notification may be made using a speaker or the like. In addition, although one destination floor indicator is installed for both going up and going down, separate indicators may be installed for each direction of car service. It is also possible to display the following.

In addition, in each of the above embodiments, only one car was allocated to one destination floor, but as a result of 11 allocation evaluations, service display sections may overlap, or when only one car cannot be multiplied by 9. There may be cases where additional baskets are allocated. In such a case, two or more cars may be assigned and the destination of a car other than the first car whose destination is displayed may be displayed. In addition, if the service display sections overlap here, 2
Allocation of more than one car means that the above destination call is additionally allocated to other cars whose service display section overlaps with the service display section of the car assigned as a result of the allocation evaluation for the registered destination call. It is to be.

〔Effect of the invention〕

As described above, in this invention, when assigning a destination call using a destination button provided at a landing to a car based on an assignment evaluation value, a floor indicating that the scheduled stop floors of the assigned cars overlap with each other The overlapping evaluation value is calculated, this is taken into consideration in the allocation evaluation value above, and the cars are allocated, and the destination floor of this allocated car is notified at the landing, so that the displayed destination floors overlap with each other. This has the effect of making it possible for passengers waiting at the landing to easily find the car they should ride by reducing the number of opportunities for them to board the car and by increasing the number of times each destination floor is displayed consecutively.
