BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator group management control system for operating a plurality of elevators simultaneously.

0003

[Prior Art] In recent years, elevator systems installed in high-rise buildings etc. have been equipped with multiple elevators.
Monitor the operation status of each elevator, comprehensively manage all elevators based on the monitoring information, and predict and respond to hall calls by selecting the most suitable car to service the floor where the call occurs. As a result, group management control systems that aim to provide services to customers in the shortest possible time are becoming widely used. By using microcomputer software, this type of group management control is made more sophisticated, allowing it to respond flexibly to the demands of the building.

However, in the conventional elevator group management control device, during times when demand is concentrated in one direction, such as when commuting to work or during lunch hours, in order to ensure transportation capacity, the system is operated as shown in FIG. The elevator of each unit is stopped only on the floors marked with a circle, and the other floors are non-stop floors.We are implementing zoned operation with non-stop floors. When carrying out zone-divided operation, the following problems occurred when non-stop floors and stop floors were set so that service could be provided to the top floor of both the low-rise zone and the high-rise zone.

That is, as shown in FIG.
A descending hall call occurs on the 5th floor, and in response to this, machine No. 1 A is assigned, and the descending hall lantern 19D of this machine A lights up, and while waiting for the service car in front of this machine A. , another car, for example, No. 2 B, is 25
If a car arrives at a floor in the ascending direction and the car becomes empty after a passenger gets off, the car in Unit 2 B, which is in the ascending direction, will receive an additional call (mainly a hall call) that should stop on the 30th floor. If so, even if the car is empty, the ascending hall lantern 19U of the second car B will flicker, making it impossible for passengers waiting in the hall to ride. However, since the notification to the waiting customers in the hall was simply the flicker of the hall lantern 19U, there was a problem in that the waiting customers, especially those who were not used to using elevators, were left with a feeling of distrust. .

[0006]

SUMMARY OF THE INVENTION As described above, the conventional elevator group management control device has a problem that, depending on the situation, it can make users feel distrustful.

[0007] The present invention was developed in view of the above-mentioned conventional problems, and when performing zoned operation with non-stop floors during times when demand in one direction is concentrated, the halls on each floor are To provide a group management control device for elevators in which a hall display device is provided for each car and necessary information can be displayed so as not to make passengers feel distrustful.

[Configuration of the invention]

[0009]

[Means for Solving the Problems] The present invention is an elevator group management control device that operates a plurality of elevators at the same time and assigns and responds to a hall call on each floor by assigning the elevator of the optimum number. In an elevator equipped with a zone division operation function having floors, a hall display device is installed in the elevator hall of each floor, and when an elevator of a machine other than the assigned machine arrives in the ascending direction at the floor where a down call is occurring, the above-mentioned A display control device is provided for displaying information on the hall display device indicating that there is a call to be answered first.

0010

[Operation] In the elevator group management control device of the present invention,
Hall display devices installed in halls on each floor when zoned operation with non-stop floors is unavoidable in order to secure transportation capacity due to demand concentrated in one direction during work hours and lunch hours. is used to display information indicating that there is a call for another floor that should be answered first when an elevator of a car number other than the allocated one arrives at the floor where a down call is occurring in the up direction. Avoid creating a sense of distrust towards waiting customers.

Further, the quasi-car call command registration circuits 4A to 4H store the hall call command assigned to the car and are reset when the car arrives at the hall call command floor, and the signal synthesis circuits 5A to 4H store the hall call command assigned to the car. 5H is car call command registration circuit 3
It outputs the logical sum of the outputs of A to 3H and the outputs of quasi-car call command registration circuits 4A to 4H.

The decoding circuit 7 decodes the output signal of the output register 11, which will be described later, and sets the secondary car call command registration circuits 4A to 4H for the corresponding floor direction of the corresponding car.

The small computer 8 is, for example, a 12-bit microcomputer, and the small computer 8 has a hall call command registration circuit 9, a hall condition table (HCT), which will be described later, and a hall request counter (HRC).
T), and elevator operation control devices 1A to 1 for each unit.
Various types of information are input and output from the output register 10, input register 11, and output register 12 to and from H, and the elevators of each car are group-managed and controlled by evaluation calculations. In the hall call command registration circuit 9, registers corresponding to the floor and direction are set when the hall call command is registered, and are reset when the car arrives at the hall call command floor. , which holds the output until the next output is issued.

Note that the arrow lines connecting the registers and interface devices with the same function of the elevator operation control devices 1A to 1H provided in each elevator indicate a plurality of parallel signal lines, for example, 12 parallel signal lines. There is. Furthermore, all the registers have the number of bits equivalent to one word of the small computer 8.

In FIG. 1, 13U and 13D are hall call push button switches for ascending and descending directions provided in the elevator halls of each car on each floor from the 1st floor to the 30th floor, for example. A hall call signal can be generated by operating the button switches 13U and 13D.

Reference numeral 14 is a hole display device whose details will be described later. Reference numeral 15 is provided on the side of the small computer 8, and has the function of converting parallel data output as a command from the small computer 8 into serial data. Reference numeral 16 is provided on the elevator hall side of each floor, and is an interface that converts serial data into serial data. These interfaces 15 are interfaces that have the function of converting into data.
and the interface 16 are connected by a serial transmission line 17.

Reference numeral 18 denotes an input/output driver that inputs parallel data converted by the interface 16 to the hall display device 14 and outputs hall call signals from the hall call push button switches 13U and 13D. 19U
, 19D is a hall lantern for displaying the allocation display for each of the ascending direction and descending direction by continuous lighting, and also for displaying the arrival display for the ascending direction and descending direction by a flicker display. It is provided for each machine.

FIG. 2 is a block diagram showing the detailed internal configuration of the hall display device 14, which includes a control circuit 14a that performs control to display a predetermined display message at a predetermined timing on the display 20, A drive circuit 14b for driving the display operation is provided.

As shown in FIG. 4, the display 20 displayed by the hall display device 14 is provided above the door of each car A to H in the elevator hall of each floor, and is designed to display the necessary information. It has become. And Figure 5
As shown in FIG. 6, for example, machine No. 1 A is assigned to the hall call of the elevator hall on the 25th floor.
If Unit 2 B, which has stopped on the 25th floor in the ascending direction and is empty because all passengers have disembarked, is assigned a descending call from the 30th floor, the display 20 of Unit 2 B will display " A message such as "Customers waiting on the 30th floor will be served first" is displayed to avoid creating a sense of distrust among waiting customers.

The car status buffers 3A to 3H of each elevator operation control device 1A to 1H are provided with a car status table CCT as shown in FIG. Various information is stored.

In addition, the small computer 8 is equipped with a hall condition table HCT as shown in FIG. The 10th bit stores information about the presence or absence of an assigned call (1 if there is an assigned call), and the 11th bit stores information about the presence or absence of a hall call (1 if there is a hall call).

Next, the operation of the elevator group management control device having the above configuration will be explained. In the flowchart of FIG. 9, when the program starts, the small electronic computer 8 is initialized (step S1), and the program proceeds to the symbol RSP. In the symbol RSP, the car index J is set to 0, and the following processing is performed starting from the first car A (step S2).

First, in symbol A, the car status information of the first car A is read from the car status information table CCT, and when all cars are completed, the process advances to symbol A1 (step S
3, S4).

At symbol A1, a traffic pattern determination routine is entered to determine what the traffic pattern is, and the traffic pattern is determined based on the clock information (step S5).

This traffic pattern determination routine is shown in FIG.
As shown in detail in the flowchart, the clock information is read using the symbol A1 (step S51), and if the driver is driving at work, the traffic pattern is set at the time of work (step S5).
2, S54a), if the driving is at lunchtime, the traffic pattern is set for lunchtime (steps S53, S54b); otherwise, the traffic pattern is set for normal time (step S54c), and in both cases, the process proceeds to symbol A2, After outputting the traffic pattern (step S55), symbol A in FIG.
Return to 3.

At symbol A3, it is determined whether the traffic pattern is a pattern in which zoned operation with non-stop floors is implemented (S6). (In the following explanation, we will explain by implementing zoned operation where only lunch time driving has non-stop floors.) Therefore, if the traffic pattern is lunch time driving, proceed to symbol C, and If not, the process advances to symbol A0 (step S6).

For symbol C, as shown in FIG. 10, the car index C is set to 0 (step S7), and the first car A
, it is checked whether the car is in a low zone or not (step S8
), it is checked whether there is a call (hall call or car call) to stop on the 30th floor (step S9), and further 25
It is checked whether or not there is a call (hall call or car call) that stops in the ascending direction on the floor (step S10), and if all the above conditions are met, the hall display 20 shows a message as shown in FIG. The message is output and the process proceeds to symbol C1 (step S11).

[0029] Furthermore, at least one of the three conditions above is satisfied.
If this does not hold true, proceed to symbol C1, and from then on,
After repeating the same process until completion for all machines,
The process advances to symbol A0 shown in 1 (step S12).

In FIG. 11, proceeding to symbol A0,
In step S13, the hole index J is set to 0, that is, 30D, and in steps S14 and S15, the state of the hole 30D is set to <10 in the hole condition table HCT.
>, <11> The determination is made by checking the bits.

First, in step S14, HCT<10>,
If it is determined that <11> is "0, 0", there is no hall call and no service elevator, so in step S16 the hall request counter HRCT (0
) is cleared to 0 (step S16), the process proceeds to symbol E1, the hole index J is incremented by 1, and the same operation is repeated (step S19).

However, in step S14, HCT
If <10> and <11> are not "0, 0", step S
15, and in step S15, HCT<10>,<1
If 1> is not “0,0”, proceed to symbol E.

[0033] In step S15, HCT<10>
, <11> are "0, 1", since a hall call has occurred and the service elevator has not yet been determined, the process advances to symbol D, and the service elevator is determined in the responding car selection routine (step S17).

A detailed flowchart of this response machine selection routine is shown in FIG. 13. When the process advances to symbol D, the allocated hall calls (n1, . . . , nk) prior to the unallocated hall calls are sent out in step S171. Then, from step S172 onwards, the predicted arrival time T for each allocated hall call and unassigned hall call of each car is calculated.
RESP(ni) is calculated. In this case, in step S172, the car index J is 0 (car No. 1 A
), and in step S173, the estimated arrival time TRESP(ni) (where i=1 to k) is determined by the following equation.

[0035]

[Math 1]

[0036] Here, TRAN(αm, βm) is
It represents the traveling time from floor αm to floor βm, and TLOS
(βm) represents the total door opening/closing time and opening time on the βm floor. Further, p is the number of floors (including the ni floor) that the car stops on the way before reaching the ni floor.

[0037] As a result, for example, if an unallocated call for 30D occurs while the car of No. 1 A is ascending the 8th floor, and at that time, No. 1 A has an already allocated call of 27D, which is a descending call for the 27th floor. The arrival time of the assigned call of 27D is determined as follows.

TRESP(n2)=TRAN(8,30)+TLOS(3
0)+TRAN(30,27) Also, the arrival time of the unassigned call of 30D is determined as follows.

TRESP(n1)=TRAN(8,3
0) Once the predicted arrival time up to the unassigned call and the arrival time of the assigned hall call prior to the unassigned call are calculated in this way, they are converted into evaluation values in step S174. In this case, conversion to an evaluation value is obtained from the relationship between the predicted waiting time Tj and the evaluation value S (=f(Tj)) shown in FIG.

[0040] In step S175, it is determined whether the above processing has been carried out for all machines. If it is determined that it has been carried out for all machines, the process proceeds to symbol C3, and in step S176 of FIG. Looking for the number lantern, put the service basket in the hall and place it in the hall lantern 19U.
Or notify by continuously lighting 19D, Figure 1
The process returns to symbol E of 1 (step S177).

Proceeding to symbol E in FIG. 11, step S
At 18, the hall request counter HR of 30D
CT(0) is incremented by +1, the hole index J is set to +1, and the process moves to symbol E1.

[0042] When proceeding to symbol E1, it is determined in step S19 whether or not the above operation has been carried out on all floors, and when it is determined that it has been completed, the process returns to RSP in FIG. 9, and thereafter, Similarly, the process is repeated cyclically.

[0043] In this way, when zone division operation with non-stop floors is carried out, a car different from the one assigned to the hall call in the descending direction arrives at the floor where the hall call occurs in the ascending direction and all passengers get off. , even if the basket is empty.
If a call from a previous floor has already been assigned to that car, the hall display device will notify that there is an assigned floor first, and the user who made the descending hall call will say, ``That's it! ” to avoid a sense of distrust.

[0044]

Effects of the Invention As described above, according to the present invention, when a zoned operation with non-stop floors is performed, if a hall call in the downward direction is occurring on any stopping floor, this hall call Even when a car other than the car assigned to the hall arrives at the floor where the hall call occurs in the ascending direction and all the passengers are unloaded, and the car is empty, the car is already assigned to the hall from the floor ahead in the ascending direction. If a call has already been assigned, the hall display will notify you that there is an assigned floor first, so the user who made the descending hall call will be able to stop at the floor where he or she is waiting. Even though there was an empty car, I didn't answer the hall call I went to, closed the door and went up further, and I felt the same disbelief as before. This will help improve the quality of the service.
