Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an elevator or response system suitable for responding to a landing call using an appropriate evaluation function by using a plurality of elevators for a plurality of floors. Relating to a group management control method for elevators that determines and responds to elevators,
In particular, this relates to control when designating the first mover on the standard floor.

In recent years, as buildings have become larger and taller, group management control of elevators that service several elevators as a group has been carried out.Group management control has a control method that switches the operation system according to traffic demand. However, the importance of this method is decreasing due to improvements in group management control technology. However, it is extremely effective when trying to operate elevators with a small amount of equipment at maximum efficiency at all times, and it is necessary to switch the operating system at least during peak and off-peak times of traffic demand.

Recently, group management using microcombinations has been developed, and the sixth data processing for detecting traffic demand can now be performed without the use of conventional complicated equipment. A control scheme such as that described above can be implemented in the container.

Generally, in office buildings, when dispatched in the morning, the demand from the standard floor is extremely high, and each elevator machine reverses its maximum call, and after returning to the standard floor, one elevator waits with the door open and becomes the designated first elevator, and other elevators Unit 0 is waiting with the door closed. After the above-mentioned morning dispatch demand is over, normal operation is resumed, there is no longer a designation for the first mover to wait with the door open on the standard floor, and when the hall call is pressed, the most suitable car is selected and responds.

Furthermore, in recent years, as hotels have become larger and more high-rise, group management control of elevators has also been implemented in hotel buildings.

The traffic demand for hotel buildings is different from that for office buildings. Generally speaking, the demand from the standard floor is not extremely high only in the morning, and since the standard floor has the front desk, lobby, etc., there is always only one aircraft on the standard floor. Increasingly, there are specifications in which the driver waits with the door open and designates the starting pitcher. Additionally, as a result of this, there are cases in which one aircraft is always on standby with the door open on the standard floor and designated as the first one, even for office flights.

In elevator group management control, an evaluation formula in an appropriate form is calculated for each car, that is, for each car, for the floor where a hall call has occurred, and the optimal car number is determined. During the A and F peak patterns, which are suitable for traffic demand where demand is extremely high, each elevator returns to the standard floor after responding to the highest call, but if there is a hall call for a floor other than the standard floor, the non-first standard There are cases where the call is assigned to a waiting car on a floor, and the call is answered from the standard floor while it is empty, resulting in a drop in service compared to the demand on the standard floor.

Also, ah! During non-peak hours, demand from the standard floor is not dominant, so there is no option other than to have the designated leading cars on the standard floor waiting to open their doors depart one after another at regular intervals. In such a demand situation, if there is a hall call for a floor other than the standard floor, the hall call may be assigned to the first machine, and the door may be closed while the standby machine on the standard floor is empty. If a call from another floor is answered, a non-starting car waiting on the standard floor or a car on another floor opens the door on the standard floor and becomes the leading car.
In this way, when specifying the first door open standby on the standard floor during normal times, the first car may shift without meeting the demand from the standard floor. However, the drawback was that it was extremely confusing for passengers. This is especially undesirable in hotels where the lobby, front desk, etc. are located on the standard floor, and there are door staff.

The present invention has been made against the background of the above-mentioned circumstances, and effectively prevents the inconvenience caused by the assignment of a hall call on another floor to the first aircraft or non-first aircraft on the standard floor when designating the first one to wait for door opening on the standard floor. The purpose of this invention is to provide a group management control method for elevators that can improve service and operational efficiency.

That is, the feature of the present invention for achieving such an object is to use a plurality of elevators for a plurality of floors and determine a response machine based on a predetermined evaluation formula for a hall call that occurs. In an elevator group management control method, when specifying the first door open standby on a standard floor, there is a mode in which the evaluation value is corrected for the first machine on the standard floor to limit allocation to hall calls on other floors, and a mode in which the first machine on the first machine on the standard floor is assigned to a hall call on another floor is restricted. At least two of the three control modes: a mode in which the evaluation value is corrected for the aircraft and its allocation to hall calls on other floors is restricted, and a mode in which the evaluation value is not corrected for either the starting aircraft or the non-starting aircraft. It has various control modes, and these control modes can be selected and switched according to traffic demand.

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

In FIG. 1, digits 1 to 9 are logic circuits, and 10 is a micro combination, a micro combination, and an input. Of the two circuits, 1 is a master condition memory circuit that stores information such as the Δ turn of operation and whether or not group control is activated for each elevator. The information table MCT is comprised of the following information table MCT. 21 Hall call memory circuits that store common hall calls for each floor as they are, JA~3H are the inter 7 chair sections of each elevator car, and car status memory circuits 4A~3H are respectively
4H, car call storage circuits 5A-jH, and hall call allocation storage circuits 6A-6H. Although FIG. 1 shows the case of eight elevator types (No. ANH), in the following explanation, the subscripts A to H corresponding to each elevator type will be omitted unless it is particularly necessary. The car status memory circuit 4 is a 12-bit register, and as shown in FIG.
Indicate the running direction, car position, car load, etc. as @O” or 1.
1” is stored as digital information, and all basket numbers are stored =
1 to 8). The car call storage circuit 5 stores the car call registration destination floors registered in each car. The hall call assignment storage circuit 6 stores the floor to which the hall call is assigned, when the hall call is the most suitable for a common hall call on each floor via the combination 10, that is, when the hall number is assigned as the optimum hall call.

7 is a hall condition memory circuit, car call memory circuits 5A to 5H, and hall call allocation memory circuits 6A to 6.
H and the information of the hall call memory circuit 22 are collected and the fourth
As shown in the figure, the fragrance of the running decision car for each destination floor and running direction, the presence or absence of a hall call for each floor and direction, and whether or not the assignment has been completed are stored, and the hall condition information table HCT is created as a whole. (index number j=l-ts).

Note that FIG. 4 shows a case where the number of floors is 10.

Reference numeral 8 denotes a wine selection circuit, which selects the information table MCT according to the designation of the selection register 11 of the computer 10.
, CCT (i) and HCT (j) are sequentially read into a RAM (random access memory) 13 via an input register 12. Reference numeral 9 denotes a decoding circuit, which determines that the elevator is the most suitable for a common hall call, and outputs it from the output register 15, and outputs the friend car number information to the index number 1 (1-1 to 8) of the corresponding car.
) and input the hall call floor numbers assigned to the memory circuits 6A to 6H for the hall call assignment of each car No. M to H.

The combination 10 includes the above-mentioned input register 12, selection register 11, output register 151RAM IJ, arithmetic circuit 14, waiting time counter 16, and other combinations,
- Contains the basic circuitry (not shown) necessary for normal operation.

The RAM J 3 stores various information obtained through the input register 12 and provides i4') meter information to the arithmetic circuit 14.

The arithmetic circuit 14 calculates the service appropriateness evaluation value f of each elevator machine using a predetermined measurement formula for each hall call based on the above-mentioned/armpit meter information, and selects the car with the smallest evaluation value f as the optimal car. and outputs it via the output register 16. The output register 15 is also composed of 12 pits and information bits as shown in FIG. 5, for example.

The waiting time counter 16 counts the number of ringing after the call registration for each floor, and calculates the waiting time count Tj for each floor.
is giving.

Next, the operation of the combination in one embodiment of the present invention applied to such a configuration will be explained with reference to a flowchart.

FIG. 6(,)(b) is a flowchart showing the main part of the overall operation, and FIG. 7 is a flowchart showing details of standard floor correction for designation of the first mover.

When the start of group control is commanded, the master controller with the configuration shown in Figure 2 is first activated as explained in Figure 1.
The condition information table MCT is read into the computer, and master conditions such as driver turn are set. Group control will not be performed unless the number of units assigned to group control reaches a predetermined number. When it is determined that group control is possible, the car status information table COT (i)
and the whole-contice information table HCT (J
) is read.

Next, if the designated starting machine is not designated, p7t
I Determine the designated car from the car status information table OCT (j) based on the status of the car status information table (j), and output the designated car from the car.

Next, the hall calls on each floor are sampled in sequence. First, the hall index j-1, that is, the down call on the top floor is checked. The presence or absence of hall calls is determined by the hall condition.
The 12th bit of the hall call information table HOT is indicated by @1"-01, and whether or not the hall call allocation is completed is given by the 1111 bit, bit @IZ@0", so the hall call discriminator determines the 11th bit. The 12th bit combination determines @00'' (no hole call), ``01'' (hole call, allocation not completed)''11'C11'C hole call completed).

In the case of 100#, the waiting time is set to Tj=0 and the process moves to the next sampling.

In the case of "11", the hall call allocation has been completed, but the waiting time count Tj is incremented by 1 every sampling cycle until the car allocated due to fullness or other conditions arrives at the floor of the hall call. It takes a long time 1)
When Tj≧L is reached, the i++ outputs a cancel signal and cancels the hall call of the car that has already been assigned to the hall call.

Hall call cancellation is performed by setting the third pin of the output register shown in FIG. 5 to 10''.

In the case of “01”, first wait time count ffj=1(
j = 1), and then begins evaluation calculations for each elevator. Assuming corner number j=l, it is determined whether this hall call can be serviced for machine A.

Then, only those machines that can be serviced move to the #f value calculation step.

Next, standard floor correction for designating the first mover is performed on the calculated evaluation value f (details will be described later).

When the process is completed for all cars, the car with the smallest evaluation value f is selected, and that car is assigned to the hall call.

When the hall call assignment is completed for j = 1, that is, the down call on the top floor, as described above, the same process is performed for j = J + 1-2, and when the optimal assignment for all hall calls is completed, Starting point, that is, the first master condition information table MC
Return to T reading and repeat sampling.

Here, an example of the standard floor correction method for designation of first mover is shown in the 7th section.
This will be explained with reference to the figures.

First, the call that is currently being evaluated using the hole index j in the connector M1.O is the standard floor ara! Since this is a correction for a hall call on a floor other than the standard floor where a judgment is made as to whether it is a call or not, if it is a call on the standard floor A or f, Δ is skipped and the process moves to the connector M. Otherwise, the next judgment is made.

That is, if it is not a standard floor up call, then the position of each car is determined based on the information in the car status information table CCT (i) reading routine.

In this case, the evaluation value 'f is corrected for the standby cars on the standard floor, and only those located on the standard floor are subject to evaluation. And, at the time of A, Pupeek/Mother turn,
Since there is a lot of demand on the standard floor, the first planes depart at fairly regular intervals. In order to limit other floor hall call assignments for cars that have returned to the standard floor, connector B1 determines whether the car currently being determined is the leading car, and a predetermined evaluation value is assigned to the non-leading car in connector ms. f・
By adding the correction value HFH08EI to the evaluation value f, the hall call assignment on other floors is restricted. (HFHOBEI'> 0)
During a mid-turn, the starting machine on the standard floor is
Considering that the demand does not always depart at regular intervals, and in order to avoid the shift of the first machine due to demand from other floors, restrictions are placed on the allocation of hall calls from other floors to the first machine. . That is, the connector B determines whether it is the first car or not, and for the first car, the connector B sets the correction value HF to the predetermined evaluation value f@.
By adding H081CI and correcting the evaluation value f,
Restrictions will be placed on hall call assignments on other floors.

In other words, since the evaluation value f is corrected for the first car or the non-first car on the standard floor, it is possible to control appropriately according to traffic demand when always specifying the first car on the standard floor. It becomes possible.

In this way, when a common hall call is assigned by determining the optimal elevator using combinations and elevators, and when the elevator group management control device performs advance designation at the standard floor, the demand from the standard floor is By restricting the assignment of other floor calls to non-starting machines on the standard floor for the extremely frequent A and A turns, we can prevent service deterioration on the standard floor and at the same time operate the entire system efficiently. is now possible, and also non-A! During peak-to-peak turns, by restricting the assignment of other floor calls to the first car on the standard floor, it is possible to prevent wasteful switching of the first car designation on the standard floor and to efficiently control the first car designation. becomes.

Note that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without changing the gist thereof.

For example, in the above embodiment, when a non-A, f peak pattern occurs, the evaluation value for the preceding aircraft on the reference floor is corrected to limit the call assignment to other floors, and, A,! During peak and temporary turns, evaluation values for non-starting aircraft on the standard floor are corrected to limit call assignments to other floors. Practically sufficient effects can be obtained even by combining them. In short, at least two modes, one that restricts the assignment of calls to other floors to the leading aircraft or non-first aircraft on the standard floor, and one that does not restrict the allocation to any of them, are set in 7, not only during Zopeak/# turns, etc. The selection can be changed according to traffic demand.

As described in detail above, according to the present invention, inconveniences due to hall call assignments on other floors to first or non-first planes on the standard floor when designating the first one to wait for door opening on the standard floor can be effectively prevented, and the service and It is possible to provide an elevator group management control method that can improve operating efficiency.
