Abstract

PURPOSE:To aim at at enhancing the service for waiting quests in a hall by giving an appropriate information by a voice message to the quests in the hall in accordance with a waiting tie determined from an optimum elevator running condition. CONSTITUTION:When a demand call is given from a hall by means of push- button switches 12U, 12D, a group-control device 8 determines a time until a servicing elevator responds and an expected arrival time and the presence of a change of servicing elevators in accordance with data of cage conditions from running control devices 1A through 1H and a cage registration signal. Further, each time when the result of the determination is given, the corresponding message is read from memory in which different kinds of messages as voice data are stored, and is issued by voice from a loud speaker 27 laid in the hall so as to give an information for an expected waiting time until arrival of an optimum elevator to guests in the hall.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention provides group management control of elevators, which allocates elevators that can respond to hall calls from each floor and performs group management control. The present invention relates to an elevator group management control device including a hall guide device that announces a message according to the operating status of an elevator assigned to a hall call.

(Prior art) When multiple elevators are operated in parallel, responses to hall calls from halls on each floor are appropriately assigned to each elevator in order to improve elevator operating efficiency and passenger service. A group management control system for elevators is being considered.

Moreover, recently it is common to instantly determine the optimal elevator when a hall call occurs and display a forecast in the hall.

In elevators with a forecast display based on group management control, the most suitable car is displayed when a hall call occurs, but it is not announced how long the most suitable car will wait before responding. Thinking that something was coming, I waited nervously in front of the forecast car stop.

(Problem to be solved by the invention) Therefore, it is conceivable to install a forecast display device using a counter system to show the wait time in the elevator hall of each floor, which shows how long it will take for the optimum car to arrive. Currently, very few buildings have put this into practical use because it is difficult to count down the waiting time according to the operation status, and the waiting time sometimes stops counting down halfway through, or the countdown suddenly slows down.

Therefore, even though it is known how long the optimal elevator will be at the time of a hall call, customers waiting in the hall are not informed of the waiting time even if there is a forecast for the optimal elevator. It just wasn't good enough.

The present invention provides elevator group management that can improve service to hall customers by sending appropriate messages as voices to the hall customers in accordance with the waiting time determined from the optimal elevator operation status. The purpose is to provide a control device.

[Structure of the Invention (Means for Solving the Problems)] In order to achieve the above-mentioned object, the present invention provides a system in which, in response to a hall call from each floor using a plurality of elevators, the car In an elevator group management control device that calculates an evaluation value based on the condition and car call registration signal, and performs group management control by assigning the most suitable elevator as a service elevator from this evaluation value, a memory in which a plurality of messages with different contents prepared by the operator are stored as voice data; and various information representing the elevator car status taken from the elevator operation control device in response to a hall call;
Understand the operating status of each elevator from the car call registration signal,
Whether the time from the generation of the hall call until the service elevator responds is less than or equal to a predetermined value, and based on the evaluation value, the predicted arrival time from when the optimal elevator is assigned as the service elevator until it arrives at the floor where the hall call is generated. determining means for respectively determining whether or not the value is below a predetermined value and whether or not the service elevator has been changed; and each time the determining means outputs a determination result, it instructs to read the corresponding message stored in the memory. and a hall guide device that reproduces the audio data of the corresponding message read from the memory according to the command from the command means and announces it as a voice from a speaker installed in the hall. It is something.

(Function) Therefore, in the elevator group management control device having such a configuration, when a hall call occurs, various information indicating the car status obtained from the operation control device of each elevator and a car call registration signal are also sent. Depending on the operation status of the elevator ascertained by the operator, the time from the generation of a hall call until the service elevator responds, and the predicted arrival time from the time the service elevator is assigned to the floor where the hall call is generated until the elevator arrives.

It is determined whether or not there has been a change in the service elevator, and each time the determination result is issued, a command is issued to read the corresponding message from the memory in which multiple different messages have been stored as audio data, so the audio data is sent to the hall. This will be announced as a voice from the installed speakers, allowing customers waiting in the hall to predict the waiting time until the most suitable elevator car arrives.

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

First, an example of the configuration of a system to which the present invention is applied will be explained with reference to FIG. In FIG. 1, IA to IH are, for example, 8

Quasi-car call command registration circuit 48~4H, signal synthesis circuit 5A~
5H is provided separately for each. Here, the car status buffers 2A to 2H are buffers that input the car status to a wiper select circuit 6, which will be described later. The car call command registration circuits 3A to 3H are set when a car call command is registered, and are reset when the car arrives at the call registration command floor. The sub-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. The signal synthesis circuits 5A to 5H are the 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.

6 is a wiper select circuit, and 7 is a decoding circuit, which decodes the output signal of the output register 11, which will be described later, and registers sub-car call command registration circuits 4A to 4A for the corresponding floor direction of the corresponding car.
This is to set 4H.

Output register 9. between IA and IH. It inputs and outputs various information from an input register 10 and an output register 11, and performs group management control of the elevators of each car by performing evaluation calculations. Here, in the hall call command registration circuit, registers for the corresponding floor and direction are set when a hall call command is registered, and are reset when the car arrives at the hall call command floor. Also, the output register 11
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 2A to 2H, which are provided in each elevator, indicate a plurality of parallel signal lines, for example, 12 lines. Furthermore, all the registers have the number of bits equivalent to one word of the small computer 8.

On the other hand, 12U and 12D are, for example, the ascending direction provided in the elevator hall of each car on each floor from the 1st floor to the 10th floor.
Each hall call push button switch 12U is a downward direction hall call push button switch.

A hall call signal is generated by operating 12D. Further, 13A to 13J are auto-announcement devices whose details will be described later. Reference numeral 14 is an interface provided on the side of the small electronic computer 8, which has the function of converting parallel data output as commands from the computer 8 into serial data. Reference numeral 15 is provided on the elevator hall side of each floor, and is an interface that converts serial data into parallel data. These interfaces 14 have the function of converting into
and interface 15 is serial transmission line 1.
They are connected by 6. Further, 17A to 17J are input/output drivers that input serial data converted by the interface 16 to the auto-announcers 13A to 13J and output hall call signals from the hall call pushbutton switches 12U and 12D.

FIG. 2 shows an example of the configuration inside the auto-announcer 13A using a block circuit. That is, as shown in FIG. 2, the auto-announcement device 13A sends a plurality of messages with different contents depending on the waiting time of the elevator prepared in advance to the elevator hall customers, for example, a message as shown in FIG. 3.

is installed.

Next, FIG. 5 shows the car status table (CCT) of each elevator operation control device IA~IH car status buffer 38~3H.
), which stores various information such as door opening/closing, running, direction, car position, load, etc.

FIG. 6 shows a hall condition table (HCT) that represents the state of the hall provided in the small computer 9. Here, it shows the presence or absence (hall call or Car call) information is stored,
Whether or not there is an assigned call in the 10th bit (rl if there is an assigned call)

FIG. 7 shows a hall request counter (HRCT) provided in the small electronic computer 9, which stores the elapsed time from the generation of a hall call for each floor and direction.

Next, the operation of the elevator group management control system constructed as described above will be explained with reference to the flowchart shown in FIG. In FIG. 8(a), when the program starts, the small computer 8 is initialized in step A1, and the program proceeds to a repeat start point (RSP). RSP
, the car index J is set to 0 in step A2,
The following processing is performed starting from machine A. First, in step A3, the car status information OCT of car A is read, and in step A4, it is determined whether the door status has changed from closed to open this time. If it has not changed to open, the process advances to symbol AOO. If the door status changes from closed to open for the first time, the car position CP(0) of car A including directionality is determined from the car position and direction using the following formulas (1) and (2).

Here, if the car position of car A is replaced with car B, . . . H, the car position can be obtained in the same way.

[When the car direction is up]

CP (0) - A car position + (FMAX-2)・
......■ [When the car direction is down] CP (0)-FMAX-A car position...
・■Here, FMAX is the number of floors of the building, and is set to 10 in this embodiment.

Based on the CP (0) obtained using the 0.0 formula, it is determined whether or not car A is currently a service car for the hall call on the floor where the door has begun to open, and if it is not a service car, the process proceeds to symbol AOO. In addition, if it is a service car, the process proceeds to step A7, and it is determined based on the hall request counter whether or not the time elapsed from the occurrence of a hall call until the service elevator responds exceeds a certain value, and a predetermined value is determined based on the hall request counter. within (usually 6
0 seconds or less), the interface 14. issues a command to the auto-announcement device on the hall CP (J) floor to output the message No. 3 shown in FIG. It is transmitted through serial transmission line 16 and interface 15. Further, if the predetermined value is exceeded in step A7, that is, if HRCT [CP(J))>LIMIT3, a command is issued to the interface 14 to output the message No. 4 in FIG. 3 in the same manner as described above. It is transmitted through serial transmission line 16 and interface 15.

It is determined in step A8 whether or not the above processing has been performed for all machines, and when it is completed, the process advances to symbol Ao.

In FIG. 8(b), when the symbol Ao is reached, the hole index J is set to O (i.e., 10D) in step A8,
Step A9. In step A10, the condition of the hole 10D is set to <10> in the hole condition table HCT.
, <11> bits are checked.

First, in step A9, HCT<10>, <11> is '0
．． 0", there is no hall call and there is no service elevator, so clear the hall request counter HRCR (0) to 0 in step All, proceed to symbol El, increment the hall index J by 1, and in step AIO set HCT<10>.

11> is “0, 1°.

Furthermore, in step AIO, HCT<10>.

11> is determined to be 0.1°, a hall call is generated and the service elevator is undetermined, so step D
Then, the service elevator is determined in the responding machine selection routine.

Here, the details of the response machine selection routine are shown in Figure 8 (
This will be explained according to the flowcharts shown in c) and (d).

That is, in FIG. 8(C), when proceeding to symbol D, the allocated hall calls (nl, . Predicted arrival time for each assigned hall call and unassigned hall call for each machine THESP (n
i) is calculated. In this case, in step A122, the car index J is set to O (car No. A),
In step A123, the estimated arrival time TRESP is determined by the following formula.
(ni) (where i −1 to k) is obtained.

σ Here, TRAN (am, βm) represents the travel time from the am floor to the βm floor, and TLO8 (βm) represents the total of the door opening/closing time and opening time at the βm floor. Also,
g is the number of floors (including nt) that the car stops on its way to n1lJji.

As a result, for example, while the car of car A is ascending to the 8th floor,
When an unallocated call of D occurs and at that time, car A has an allocated call of 7D on the 7th floor DOWN, the arrival time of the allocated call of 7D is determined as follows.

TRASP (n2) ■TRA N (8,10)+ T L OS (1
0)+ T R A N (10,7)
...... ■Also, the arrival time of the unallocated call of 10D is determined as follows.

TRAS P (n 1) = TRAN (8, 10) --
■If we calculate the predicted arrival time up to the unassigned call and the predicted arrival time of the allocated hall call before the unassigned call in this way,
In step A124, conversion into an evaluation value is performed. In this case, conversion to an evaluation value is obtained from the relationship between the predicted waiting time Tj and the evaluation value f(Tj) shown in FIG.

It is determined in step A125 whether the above process has been carried out for all machines, and if it is determined that it has been carried out for all machines, the process advances to symbol C3, and step A12
In step A127, it is determined whether the predicted arrival time to the hall 10D with the evaluation value S of 0PTC is less than or equal to a predetermined value.

If the predicted arrival time of 0PTC to 10D is less than a predetermined value (LIMIT is usually set to 30 seconds), a command is issued to the interface 14. to output the message NO, 1 shown in FIG. It is transmitted to the auto-announcer device through a serial transmission line 16 and an interface 15. Also, if the predicted arrival time of 0PTC to 10D exceeds LIMIT, NO as shown in FIG.

Interface 1 commands to output message 2.
4. It is transmitted to the auto-announcer device through a serial transmission line 16 and an interface 15. When such a command is issued, the process advances to symbol C4, and further, in step A128, a service basket (OPT) is placed in the hall.
C) is announced by a hall lantern, Figure 8 (b) 4v
Proceed to symbol E.

Proceeding to symbol E in FIG. 8(b), the hall request counter HRCT (0
) is incremented by +1, and the hole index J is +
1 and move on to check 9D.

On the other hand, symbol D1 (i.e. HCT
When <10> and <11> are "11" or "10")
In step A14, HCT<10>, <11
> is 111", and if it is "11", the process advances to symbol F and moves to the long-term matching routine in step A15. Here, when HCT<10> and <11> are 10", the service Since the elevator has started to decelerate to 10D, the process does not proceed to the long-term waiting routine, but in step A13, the hall request counter HRCT (0) is incremented by +1, and the process proceeds to check the next floor.

Here, the processing contents of the long-term maintenance routine will be described with reference to the flowchart shown in FIG. 8(e). That is, in FIG. 8(e), 10D in step A151.
The elapsed time (HRCT (J)) from the generation of a hall call is set to a predetermined value (usually 40 to 5 at LIMIT2).
Set a value between 0 seconds) to determine whether the value has been exceeded,
If not, proceed to symbol E. Moreover, if it exceeds a predetermined value, it is determined in step A152 whether or not it is better to change the forecast. In this case, various methods have been proposed to determine whether it is better to change the forecast (for example, the difference between the predicted arrival time of the service elevator to 10D and the predicted arrival time of other elevators) In this embodiment, the process is performed when the forecast is changed, so a detailed explanation thereof will be omitted.

Therefore, the hole request counter HRCT of 10D
When (0) exceeds LIMIT2, step A153
At the same time, the forecast change output is output by N01 shown in Figure 3.
Interface 1 commands to output message 5.
°4. Serial transmission line 16 and interface 15
The signal is then transmitted to the auto-announcer through the signal line and proceeds to symbol E in FIG. 8(b).

Proceeding to symbol E in FIG. 8(b), it is determined in step A16 whether or not the above-described processing has been carried out on all floors, and if it is determined that the processing has been completed, the process moves to the repeat start point (R9P). After returning, the same process is repeated cyclically.

In this way, in the process of elevator group management control, the auto-announcer 13A is activated every time the time required for a service elevator to arrive at the hall call floor for a hall call is determined.
~13H was given a command to select the messages shown in Nos. 1 to 5 in Figure 3, and a voice announcement was made from the speaker 27, so that the customers waiting in the hall would know that the car in the most suitable elevator had arrived. It becomes possible to predict the waiting time until the waiting time, which eliminates anxiety for waiting customers and improves the service.

[Effects of the Invention] As described above, according to the present invention, an appropriate message is played as voice to the customers waiting in the hall according to the waiting time determined from the optimal operating state of the elevator. It is possible to provide an elevator group management control device that can improve the service of elevators.
