Abstract

PURPOSE:To smoothen people getting on and off of an elevator by judging at arrival of elevator cage whether any passenger is getting off in accordance with the cage call information, and if anybody is, informing the people at the hall that there is a passenger or passengers who are getting off. CONSTITUTION:A cage call register circuit 3A and a subsidiary cage call register circuit 4A are furnished in elevator operation control devices 1A-1H for floor, and when a cage arrives at the command floor, they will be reset. Hall call push button switches 12U, 12D and auto-anouncing devices 13A-13J are furnished at each floor, and speaker is installed in devices 13A-13J. When a cage call is registrated, it undergoes a computation by a small computer and is converted into serial data by an interface 14. When the hall call push buttons 12U, 12D are pushed, on the other hand, the signal is converted into parallel data by another interface 15, which is connected with the interface 14 by a transmission line 16 through an input/output driver 17. The data is notified to the people at the hall from the speaker 27 through the input/output driver 17.

[Purpose of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guiding method in elevator group management control.

0002

[Prior Art] In recent years, elevator systems installed in high-rise buildings, etc., monitor the operation status of each elevator installed in a plurality of elevators and comprehensively manage all elevators based on the monitoring information. In response to a call, a group management control system that predicts and selects the most suitable car to serve on that floor and responds, thereby providing service to customers in a short time, has become widely used. It's coming. Control using software from microcomputers has made them highly functional, making it possible to respond to building demands with flexible control.

0003

[Problem to be solved by the invention] On floors with a large number of users, such as the standard floor, cafeteria floor, and transfer floor, boarding and alighting are carried out frequently, so there is often confusion between passengers trying to board and passengers trying to get off. There is a risk of unexpected accidents such as collisions with other vehicles, and if unnecessary time is spent getting on and off, there is a problem that services on other floors will deteriorate.

[0004] An object of the present invention is to provide an elevator guidance method that can improve the service to elevator users by appropriately broadcasting information to the users waiting in the hall, such as informing them that there are people getting off. It is to provide. [Structure of the invention]

[0005]

[Means and operations for solving the problems] In order to achieve the above object, the present invention performs group management control for allocating optimal car numbers to hall calls on a plurality of floors. When the elevator arrives at a floor, it detects whether there are people getting off at that floor (whether there is a car call or not), and guides and informs the users waiting in the hall that there are people getting off. Service to users can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 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, 1A to 1H are elevator operation control devices provided for each of eight elevators, for example, and car status buffers 2A to 2H are
, car call command registration circuits 3A to 3H, quasi-car call command registration circuits 4A to 4H, and signal synthesis circuits 5A to 5H are provided separately. 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. Signal synthesis circuit 5
A to 5H output the logical sum of the outputs of the car call command registration circuits 3A to 3H and the outputs of the 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 sets the quasi-car call command registration circuits 4A to 4H in the corresponding floor direction of the corresponding car. It is. 8 is a small computer using, for example, a 12-bit microcomputer, and this small computer 8 is equipped with a hall call command registration circuit, a hall condition table (HCT), and a hall request counter (HRCT), and is connected to the elevator operation control device 1A of each car. to 1H, various types of information are input and output from the output register 9, input register 10, and output register 11, and the elevators of each car are group-managed and controlled by 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. Further, the output register 11 holds the output until the next output is output.

Note that the arrow lines connecting the registers and interface devices with the same function of the elevator operation control devices 2A to 2H provided in each elevator indicate a plurality of parallel signal lines, for example, 12. There is. 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, 1
Hall call push button switches for ascending and descending directions are provided in the elevator hall of each car on each floor up to the 0th floor, and a hall call signal is generated by operating each of these hall call push button switches 12U and 12D. Also, 13A~
13J is an auto-announcement device whose details will be described later. Reference numeral 14 is provided on the side of the small electronic computer 8, and is an interface having a function of converting parallel data outputted as a command from the computer 8 into serial data. Reference numeral 15 is provided on the elevator hall side of each floor, and is used to convert serial data into parallel data. These interfaces 14 and 15 are connected by a serial transmission line 16. Furthermore, 17A to 17J are interface 1
The serial data converted in step 6 is input to the auto-announcement devices 13A to 13J, and the hall call pushbutton switch 1
This is an input/output driver that outputs hall call signals from 2U and 12D.

FIG. 2 shows a block circuit example of the internal structure of the auto-announcer 13A. That is, as shown in FIG. 2, the auto-announcement device 13A sends a message in advance to users waiting in the elevator hall to report if there is a person getting off when the car arrives (there is a car call), for example, as shown in FIG. When command data is inputted through the memory 18, the input/output buffer 19, and the input/output port 20 in which a message as shown in FIG.
8, a parallel/serial conversion circuit 22 that inputs the audio data read out by the CPU 21 through the input/output port 20 and converts it into a serial signal, and converts the audio data into a bit rate serially converted by the parallel/serial conversion circuit 22. A decoding device 23 decodes a synchronized digital signal into an analog signal according to predetermined rules, and an amplifier 24 and a high-pass/low-pass filter 2
5, a speaker 27 that outputs audio via a main amplifier 26.

FIG. 4 is a front view of a hall on the second floor, for example, in which the hall call pushbutton switches 12U, 12 in the ascending direction and descending direction are shown.
The above-mentioned auto-announcement device 13 is placed on the hoistway side next to D.
B is set, and a speaker 27 is attached toward the front of the hall.

Next, FIG. 5 shows each elevator operation control device 1.
This shows the car status table (CCT) of the car status buffers 3A to 3H of A to 1H, in which various information such as door opening/closing, running, direction, car position, load, etc. are stored.

FIG. 6 shows a hole condition table (H
CT), and here the 0 to 7 bits store information on whether each floor and car is scheduled to stop (hall call or car call), and the 10th bit indicates whether there is an assigned call or not (if there is an assigned call). 1) Information indicating the presence or absence of a hall call (1 if there is a hall call) is stored in the 11th bit. Next, the present invention will be explained with reference to flowcharts shown in FIG. 7 and subsequent figures.

That is, when the program starts, it initializes the small computer and then proceeds to the symbol RSP. RSP
Now, the car index J is set to 0, and the following processing is performed starting from car A. First, at symbol A, the car state information CCT of car No. A is read and when all cars are completed, the process proceeds to symbol C.

In FIG. 8, the car index C is set to 0 with symbol C, and it is checked whether there is a car call in car A and whether there is a hall call in the same direction on the floor where the car call is located, and if all the above conditions are met. When this is true, the auto-announcer 13A outputs a voice message at the timing when the car starts decelerating to stop at that floor, and the process proceeds to symbol C1. Next, it is determined whether or not the above-described processing has been performed for all machines, and if it is determined that the processing has been completed, the process advances to symbol A0.

In FIG. 9, when the symbol A0 is reached, the hole index J is set to 0 in step A8, and step A
9. In step A10, the state of the hole is determined by checking bits <10> and <11> of the hole condition table HCT. First, step A9
If it is determined that HCT<10> and <11> are "0,0", there is no hall call and there is no service elevator, so clear the hall request counter HRCT(0) to 0 in step A11 and proceed to symbol E1. The hole index J is incremented by 1, and the hole condition table HCT for the next hole is checked. In step A10, HCT<10>, <11> is “0,”
1". In this step A10, H
If CT<10> and <11> are not "0, 1", proceed to symbol E. Furthermore, in step A10, HCT
If it is determined that <10> and <11> are "0, 1", a hall call has occurred and a service elevator has not yet been determined, so the process proceeds to step D, and a service elevator is determined in a responding car selection routine.

The details of the response machine selection routine will now be explained with reference to the flowcharts shown in FIGS. 10 and 11. That is, in FIG. 10, when proceeding to symbol D, the allocated hall calls (n1,...nk) ahead of the unallocated hall calls are selected in step A121, and then in step A12
2 From then on, the predicted arrival time TRESP(ni) is calculated for each assigned hall call and unassigned hall call for each car. In this case, in step A122, the car index J is set to 0 (car No. A), and in step A123, the estimated arrival time TRESP(ni
) (where i=1 to k) is calculated.

Here, TRAN (αm, βm) represents the traveling time from the αm floor to the βm floor, and TLOS (βm) represents the total of the door opening/closing time and opening time at the βm floor. Further, l is the number of floors (including ni) that the car stops on the way before going to the ni floor. As a result, for example, if an unassigned call of 10D occurs while the car of car A is ascending the 3rd floor, and car A has an assigned call of 7D on the 7th floor DOWN at that time, the arrival of the assigned call of 7D. The time can be calculated as follows. TRASP(n2)=TRAN(3,10)+TL
OS (10)
+TRAN(10,7)
...(2) Also, the arrival time of the unallocated call of 10D is determined as follows. TRASP(n1)=TRAN(3,10)
...(3)

[0020]
Once the predicted arrival time up to the unassigned call and the predicted arrival time of the assigned hall call ahead of the unassigned call are calculated in this way, conversion into an evaluation value is performed in step A124. 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 or not 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;
At step A126, the evaluation value S is the smallest machine (OPTC
), the service car (OPTC) is announced to the hall using the hall lantern, and the process proceeds to symbol E in FIG.

Proceeding to symbol E in FIG. 9, step A1
3, the hall request counter HRCT of 10D (
0) is incremented by +1 and proceed to symbol E1. In step A16, it is determined whether or not the above-described processing has been carried out on all floors. When it is determined that the processing has been completed, the process returns to the repeat start point RSP, and the same processing is repeated thereafter.

[0023]
