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, an elevator registers a hall call using an up or down button installed at the hall, and uses this hall call to summon a car. When the car arrives, a passenger gets on board and presses a destination button inside the car to register a car call, and the car responds to the car call and completes a series of services.

Recently, by installing a control panel with destination buttons at the landing and registering the destination call directly at the landing, it is possible to improve the operability of the buttons and to know the destination floor before the car responds to the landing. For example, Utility Model Publication No. 53-40843 aimed at improving management performance.
This is shown in the publication No.

Figure 13 is a diagram showing the second floor landing of the conventional group control elevator, in which X and Y are the landing doors of the first and second cars, respectively, and 10 is the destination button for the first floor and the third to eighth floors. 1A, 3A to 8A are arranged, and the corresponding destination call is registered in common for Units 1 and 2. 11X and 12X are the up and down arrival warning lights of Unit 1, and 11Y and 12Y are the same as 2. Arrival warning light of Unit 1, 13X, 13Y is 1
This is a destination floor indicator that displays the destination floors of Car No. 2 and Car No. 2.

That is, assume that the destination buttons 5A to 8A for the 5th to 8th floors are pressed at the landing on the 2nd floor. With this, the second floor landing call is registered, and at the same time, the destination calls by the destination buttons 5A to 8A are 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. In other words, a landing to be assigned to a car is selected and provisionally assigned to each car, the estimated service time for each of the landings already assigned to each car and the temporarily allocated landing is calculated, and the service status evaluation value for these is calculated. The evaluation value is calculated and the car is allocated based on the evaluation value (the calculation of the evaluation value will be described later).
As a result, if the destination calls for the 6th and 8th floors are assigned to Car No. 1, and the destination calls for the 5th and 7th floors are assigned to Car No. 2, these destination floors will be displayed on the destination floor displays 13X and 13Y, respectively. Ru. Now, after the No. 1 and No. 2 cars have each arrived at the second floor, they will head to their respective assigned floors.

[Problem that the invention seeks to solve]

In the conventional elevator group management device as described above, when many destination calls are registered for the same direction on the same floor, multiple cars are allocated when one car cannot handle the calls. At this time,
The destination floor will be displayed for each car, but passengers waiting at the landing must find out which car they should board from among the destination floor indicators 13X and 13Y. The problem with the display as shown in the figure is that when there are many cars and a large number of floors, it is difficult to find the car and waiting passengers move back and forth in the landing 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]

In the elevator group management device according to the present invention, when assigning a destination call to a car using a destination button provided at a landing, a floor overlap evaluation value indicates that the scheduled stop floors of the assigned cars overlap with each other. This system is equipped with a floor polymerization evaluation means that calculates and introduces this value to select a cage so that the degree of polymerization described above is reduced.

[Effect]

In this invention, by introducing the above-mentioned floor overlapping evaluation value and selecting cars so that the above-mentioned degree of overlapping is reduced, the chances of the destination floors displayed at the landings overlapping each other with the assigned cars are reduced, Increase the degree to which each destination floor is displayed consecutively.

[Embodiment] 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 1A, 3A to 8A, etc. are collectively referred to as A) installed at the boarding point is pressed, the destination call is registered. The destination call allocating means 16 calculates an 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 17, 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 13 at the landing (in this embodiment, a destination floor indicator using an indicator light is used). On the other hand, the floor overlap evaluation means 18 calculates a floor overlap evaluation value indicating that the scheduled stop floors of the assigned cars are overlapped with each other, and introduces this into the above-mentioned allocation evaluation value. It is configured to reduce the chance that the destination floors displayed on the display 13 overlap with each other in the assigned cars.

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

In the figure, 20 is a car control microcomputer (1
It has a configuration similar to that shown in, for example, Japanese Patent Application Laid-open No. 51-53354, and includes a central processing unit (hereinafter referred to as CPU) 20A,

It has a conversion device 20E that converts the signal level. 21 is a group management microcomputer that is also composed of microcomputers, and similarly
CPU21A, storage device 21B, transmission device 21C
It also has a conversion device 21D that converts the input/output level for the destination button A at the landing.

FIG. 3 shows two parts of the elevator according to the embodiment shown in FIG.
It is a front view of a floor landing.

In the figure, X, Y, 1A, 3A to 8A, 10 are the first
This is similar to Figure 3. Z is the landing door of Unit 3,
13X to 13Z are destination floor indicators for the first to third cars.

Figure 4 shows the destination call registration floor H registered for each hall operation panel on each floor, with the hall operation panel installed floors i (=1, 2, 3...8) in the vertical direction and the hall operation panel in the horizontal direction. Destination registration floor j (=1, 2, 3...
8) are shown respectively. For example, if Hij="1", this indicates that the destination call for the j-th floor row of the i-th floor landing is registered.

FIG. 5 shows the allocation status of each floor to the destination call for each car, and W ₁ to W ₃ indicate the assigned floors for cars No. 1 to No. 3, respectively. For example, W ₁ ij=
If it is "1", it indicates that the first car is assigned to the destination call on the j floor of the i floor landing.

In addition, the above destination call registration floor H and assigned floor W ₁ ~
W ₃ is the storage device 21B of the group management microcomputer 21.
The array is set in RAM.

FIG. 6 shows an example of the car allocation status and destination floor display. For example, 1st floor on 2nd floor, 4
For the destination calls for the 1st floor, 6th floor and 8th floor, the 1st floor destination call is for Unit 1, and the 4th and 6th floor destination calls are for Unit 2.
This indicates that the destination call for the 8th floor is assigned to Car No. 3. The first floor is displayed on the second floor destination floor display 13X, the fourth to sixth floors are displayed on the destination floor display 13Y, and the seventh and eighth floors are displayed on the destination floor display 13Z. Here, the 5th floor is not assigned to Unit 2, but by displaying the 4th to 6th floors consecutively, it will be easier for waiting customers to see.
It is displayed like this. 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 Unit 3, there is only the 8th floor assigned to the 2nd floor, but since the 8th floor is assigned to the 8th floor destination call on 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 may also do so. 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 overlap each other, as shown in assigned floors W ₁ to W ₃ . It is thought that it is better to allocate them consecutively and not allocate them simultaneously.

Also, considering the efficiency of group management, the destination floors of each car should not overlap each other, including not only the destination call on that floor, but also the floor where the car is scheduled to stop on the previous floor.
And continuous allocation is better. 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 group management microcomputer 21.
FIG. 8 shows a subprogram of the program stored in the ROM of the storage device 21B, and FIG. 9 shows details of one processing step in FIG. FIG. 10 is a flow chart of the operation according to the program stored in the storage device 20B of the car control microcomputer 20.

When destination button A is pressed at each floor landing, the above
The destination call registration operation is performed by a 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 31 of FIG. 7, the scanning installation floor i ₀ is set to zero, and in step 32, the scanning destination floor j ₀ is set to zero, thereby initializing the scanning installation floor and the scanning destination floor, respectively. In step 33, the scanning installation floor i ₀ is set to i ₀ +1, and in step 34, the scanning destination floor j ₀ is set to j ₀ +1, and the scanning installation floor and scanning destination floor are updated one floor at a time. In step 35, check whether the call for the i _0th floor boarding area to the j _0th floor is registered.
It is judged whether Hi ₀ j ₀ is _" 1" or not, and if it is registered, in step 36 _it is determined whether these destination floor calls are _unassigned or _{not .} The determination is made based on whether both ₀ and W ₃ i ₀ j ₀ are "0". That is,
i ₀ of the landing hall j ₀ It is determined whether the call to the 0 floor has been assigned, and if it is not assigned, in step 37, execute the subprogram WAR1 shown in FIG _.
Select the car to be assigned to the call bound for floor _j0 .
If in step 35 a call bound for the _j0 floor of the _i0th floor landing is not registered, and if in step 36 a car has already been assigned, step 37 is not executed and the process jumps to step 38. In step 38, it is determined whether the scanning of the destination floor has been completed, and if it has not been completed, the process returns to step 34 to continue scanning. If the scanning of the destination floor is completed, it is determined in step 39 whether the scanning of the installation floor is completed, and if it is not completed, the process returns to step 33 and the scanning is continued.

Next, in step 37A of FIG. 8, the allocated car number K is set to zero, the allocated car storage data is cleared, and in step 37B, the maximum value (the smaller the evaluation value, the better) is set in the memory that temporarily stores the result of the evaluation value _E. ). In step 37C, the scan number _k0 is set to zero to initialize the scan number, and in step 37D, the scan number _k0 is set to _k0.
As +1, the scanning number is updated one by one. In step 37E, the floor overlap evaluation value e(k ₀ ,
i ₀ , j ₀ , i) are calculated. This subprogram is shown in FIG. 9, and this floor polymerization evaluation value e(k ₀ , i ₀ ,
j ₀ , i) continuously captures the i _0th floor of car k ₀ and the scheduled stopping floor in front of it, and indicates the overlap with the scheduled stopping floors of other assigned cars.

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

This is calculated by adding the waiting time for all destination calls at each landing (including those not assigned to car k ₀ ) when the above allocation is made to car k ₀ , and the service time after boarding. Furthermore, a floor polymerization evaluation value e (k ₀ , i ₀ , j ₀ , i) is introduced to perform a comprehensive evaluation. Here, Rkij is the expected arrival time required for car K to arrive at floor i, Tij is the time since the call for floor j is registered on floor i, that is, the duration, and Skij is the time required for car K to arrive at floor i. Each indicates the time required to reach the j floor, that is, the service time (boarding time), and Wkij is each element of the assigned floor shown in Fig. 5. It is 1 when it is allocated, and it is 0 when it is not allocated.

In this way, the assigned evaluation value Ek ₀ is j ₀ on floor i ₀
Service evaluation value for the call to the floor (Rk ₀ i ₀ j ₀ + Ti ₀
j ₀ +Sk ₀ i ₀ j ₀ ), each destination call that has already been registered and assigned (assigned destination calls are i ₀ floor and
j By assigning a new call to floor ₀ ,
(Waiting and service times may be longer)
is evaluated by adding them all together using 〓 ^k 〓 ⁱ 〓 ^j (Rkij + Tij + Skij) × Wkij. Then, the floor polymerization evaluation value e (ki ₀ j ₀ i) obtained in step 37E is
By weighting with (predetermined numerical value) and adding all the floor overlap evaluation values, it is evaluated as bad when the i _0th floor and the floor scheduled to stop in front of it overlap with other units.

Note that the means for calculating Rkij and Tij are calculated in the same manner as a known group control device using normal elevator up and down calls, and Skij is calculated in exactly the same manner as Rkij. Therefore, although not shown in the figure, since the destination floor at floor i is known before arriving at floor i, it is not only possible to stop at the installation floor by assignment as a stop floor, but also to stop by calling the destination from the installation floor. It can be calculated by using the floor as a deterministic element.

Next, in step 37G, it is checked whether the assigned evaluation value Ek ₀ in step 37F is smaller than the best evaluation value E ₀ so far, and if it is smaller than the best evaluation value E ₀ , the basket k ₀ is assigned in step 37H. A new selection basket k is set, and the best evaluation value E ₀ is also updated to Ek ₀ . If the assigned evaluation value Ek ₀ is not smaller than the best evaluation value E ₀ in step 37G, step 37H is not executed. In step 37I, it is determined whether scanning has been completed for all machines, and if it has not been completed, the process returns to step 37D. Once scanning is complete, proceed to step 3
In step 7J, the best car k so far is set as the allocated car. Also, Wk ₀ i ₀ j ₀ is set to 1.

Next, the operation of calculating the floor polymerization evaluation value using the subprogram shown in FIG. 9 will be explained.

This means that if scanning machine k ₀ is assigned the call of destination floor j ₀ of installation floor i ₀ , the destination floor on installation floor i (floors 1 to 8) will overlap with other machines. This is used to check, and to set a floor polymerization evaluation value e (k ₀ i ₀ j ₀ i) if polymerization occurs. Here, the overlap with other cars on the destination floor refers to the service display section of each car, which will be described later. The service display section is set by considering the scheduled stop floor of each car as a continuous scheduled stop floor even if there is no plan to stop midway.For example, if the actual scheduled stop floor of a certain car is the 4th floor. , 4 for the 5th and 8th floors
All floors from the 8th floor to the 8th floor are considered to be the destination floors.

Furthermore, if you define the planned stop floor in detail, the assigned floor
On _W1 to _W3 , at least one set floor has a destination call assignment, all assigned destination call floors, and the car call floor already registered in the car. However, by the time the car arrives at installation floor i, it has been serviced by that car or another car, and i
Floors for which there is no longer a need for service after departure from the floor are excluded from the floors scheduled for stopping at the i floor.
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 manner, in FIG. 9, the overlap of the service display sections of each car is determined for each floor i. In this case, the floor polymerization evaluation value e (k ₀ i ₀ j ₀ i) has a value of 0, 1, or 2 since there are three cars.

Now, in step 37E1, initial setting of the scan setting floor is performed by setting the scanning installation floor i to zero, and in step 37E2
Set the scan setting floor i to i+1 and set the scan installation floor i to 1.
Update each floor. In step 37E3, the service display section J ₁ to _{J 2} on the installation floor of the scanning machine k ₀ is calculated.
Here, J ₁ is the lowest floor in the above section, and J ₂ is also the highest floor. In this case, both the i _0th floor and the j _0th floor are included as the scheduled stop floors. Step 37
In E4, the service display section at the installation floor i of the car other than scanning car number k ₀ is calculated. In this case, j ₀ on floor i ₀
Calls to the floor will not be considered. In step 37E5, the floor polymerization evaluation value e (k ₀ i ₀ j ₀ i) is reset to zero. In step 37E6, if a car other than the scan number k ₀ is scanned and its service display section overlaps with that of the scan number k ₀ , 1 is added to the floor overlap evaluation value e (k ₀ i ₀ j ₀ i). to add. In step 37E7, it is determined whether the scanning of the installation floor has been completed, and if it has not been completed, the process returns to step 37E2.

FIG. 10 shows the destination display control operation program for the destination floor indicators 13X to 13Z. Here, the assigned destination floor Wij for each installation floor sent from the group management microcomputer 21 to each car and the destination floor already registered as a car call are shown in FIG. Based on the destination call, it is determined whether or not to light up each destination floor display 13 at each landing, and the result is output to the destination floor display 13. That is, for each installation floor, if that floor is a planned stop floor, the above-mentioned service display section is determined for that floor, and all indicator lights corresponding to the destination floor within that section are turned on.

In step 41, the scanning installation floor is initialized, and in step 42, the scanning installation floor is updated one floor at a time. Step 4
In step 3, assign floor W ₁ (or
W ₂ , W ₃ ) Determine whether there is an installation floor to which a destination call is assigned above, or whether it is a floor with an assigned destination call or a floor with a destination call already registered in the car. Here, as explained in FIG.
<Is there an installation floor that has a destination call assigned?>
You can go alone.

In step 44, the service display sections J ₁ to J ₂ on the installation floor i are calculated in the same manner as explained in FIG. In step 45, the scanning destination floor is initialized, and in step 46
The scan destination floor is updated one floor at a time. In step 47, determine whether to display the route to the j floor from the i floor J ₁ ≦j≦J ₂
In other words, the j floor is the service display section J ₁ ~
Judgment will be made based on whether it is included in J ₂ . If it is determined that the display is to be displayed, the indicator light for the j floor on the i floor is turned on in step 48. If it is determined that it will not be displayed,
In step 49, the indicator light for the J floor on the i floor is turned off. In step 50, it is determined whether the destination floor scanning has been completed, and if it has not been completed, the process returns to step 46. 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 42. In addition, step 4
If it is determined in step 3 that the i floor is not the scheduled stop floor, all indicator lights for the i floor are turned off in step 52, and step 51
fly to

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

11 and 12 show other embodiments of the present invention, FIG. 11 is a front view of the destination floor display 13X, and FIG. 12 is a destination display control operation program,
This corresponds to FIG. 10. Here, the destination floor is displayed on the destination floor display 13X in the form of J _1st floor to J _2nd floor.

In step 61, the scanning installation floor is initialized, and in step 62, the scanning installation floor is updated one floor at a time. Step 6
In Step 3, it is determined whether the i floor is a scheduled stop floor, and if it is, in step 64, the service display sections J ₁ to J ₂ on the installation floor i are calculated. In step 65, the lowest floor J ₁
will be displayed on the left indicator light, and the top floor _J2 will be displayed on the right display, etc. In step 66, it is determined whether the scanning of the installation floor has been completed, and if it has not been completed, the process returns to step 62. If it is determined in step 63 that the i-th floor is not the planned stop floor, the i-th floor indicator light is turned off in step 67, and the process jumps to step 66.

Note that in each of the above embodiments, a destination floor indicator is used as the destination floor indicator, but audible notification may be made using a speaker or the like. Further, although one destination floor display device is shown for both up and down directions, separate display devices may be installed for each service direction of the car. Furthermore, it is also possible to display the name of the car being serviced on the destination floor.

In addition, in each of the above embodiments, only one car is allocated to one destination floor, but additional cars may be allocated when service display sections overlap as a result of allocation evaluation or when it is not possible to get through with just one car. There may be cases where you do this. In such a case, move the basket to 2
It is also possible to allocate more than one car and display the destination of a car other than the first car whose destination is 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 allocation evaluation for the registered destination call. It is.

〔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, a floor overlap evaluation value is calculated, which indicates that the scheduled stop floors of the assigned cars overlap with each other. ,
By introducing this, cars are allocated in such a way that the degree of overlap described above is reduced, and the destination floor of this allocated car is notified at the landing, thereby reducing the chance that the displayed destination floors overlap with each other. However, by increasing the number of consecutive destination floors, passengers waiting at the landing can easily find their own car.
