Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention is directed to the improvement of a liver flow control system for an elevator in which a destination button is provided at a landing.

[Technical background of the invention and its problems]

In an elevator group management control device that manages a plurality of elevators as a group, a landing button having up and down buttons is usually installed at the elevator landing. Passengers at the boarding station can press the button for the direction they want to go (
Passengers who want to go up press the up button, passengers who want to go down press the down button) to issue a hall call command and call for the car.

In recent years, group management control devices using microcomputers have been used to determine which elevator is the most rational to respond to.
The responding machine is determined by performing an evaluation calculation using a predetermined evaluation formula or the like. Among the hall lanterns on the floor of the elevator, the hall lantern in the same direction as the hall call lights up as a warning light to inform passengers that the elevator is scheduled to respond. When the basket responds to the call and approaches its base, the lit hall lantern flashes to indicate its arrival, and the door opens almost as soon as it lands. Passengers boarding the arriving car press the destination floor button on the car control panel to register the car call. The car again operates while responding to car calls and assigned landing calls.

However, in this method, the destination floor of a passenger at the landing is unknown until the passenger boards the car and presses the destination floor button on the car control panel, so the group management control device determines the destination floor of the passenger based on past statistical data. There was no choice but to guess based on the learning results. Therefore, it is not possible to operate the car in the near future by accurately considering the destination floor of the passengers at the landing, and when considering the building as a whole, the waiting time for the passengers at the landing becomes long. Also, when the car is crowded, people are often pushed to the back of the car before they can register the car call on the car control panel when boarding the car. It was necessary to come out and operate it, which made me feel shy and uncomfortable.

In order to improve this problem, it has been proposed to provide a destination button at the landing, as shown in FIG. In the example of 3 cars/group, IA, IB, and IC are the landing doors 2A and 2B on the 3rd floor of aircraft A to C, respectively.

2C is the hall lantern for ascending cars A to C, respectively.
3A, 3B, and 3G are also hall lanterns for getting off. , 4 are 1.2. Destination buttons H1 to H6 for the 4th to 6th floors are arranged, and the hall operation panels 5A, 5B, and 50 are used to register the corresponding calls respectively.
An indicator light is installed on the top of C and displays a number or letter corresponding to each floor, and is a destination indicator that indicates the destination of cars A to C when lit.

Now, with such a configuration, when the destination button (Hl, H2, H4, H5, H6 for the third floor) is pressed at each floor landing, these calls are assigned to each car by a well-known assignment device. .

In this way, the information from the landing, which was conventionally limited to only going up and getting off, is given as a more clear destination floor, so the accuracy of the allocation is increased, and the optimal car can be allocated to each car.

The results are displayed on the destination floor indicators 5A to 5C.

In the diagram, the 1st floor number is designated as C, the 4th floor is designated as B, and 5
The floor name indicates that it is assigned to A@ machine. Now, passengers going to the 1st floor will be put on the C train, passengers going to the 4th floor will be on the B train, and passengers going to the 5th floor will be on the A @ machine, so the number of stops will be minimized. be able to.

However, with this method, if a prank call Tj (such as intentionally pressing multiple buttons on floors other than the intended floor) occurs to the destination buttons H1 to H6, those calls would call only one elevator and Whereas the effect was only to stop the elevator once, multiple elevators will be called and stopped, and the floor where the destination button was pressed will also be stopped. Therefore, the destination button system has the disadvantage that it is strongly influenced by prank calls, reducing the efficiency of the entire system and increasing passengers' distrust of group management.

[Object of the present invention]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an elevator group management control system that eliminates the above-mentioned drawbacks and can minimize damage even if a mischievous call occurs.

[Summary of the invention]

In order to achieve the above object, the present invention provides a destination button on a hall operation panel installed in an elevator hall where a plurality of cars are installed, and by operating the destination button, a car is assigned to a registered call, and the car is in which the elevator is operated to a registered floor by operating the destination button, the number of passengers waiting at the elevator landing is detected by a detection device for detecting the number of passengers waiting at the elevator landing; A destination button operation number detection device that issues a corresponding output, and a destination button cancellation device that cancels registration of the destination button on the floor when a difference in output voltage of the device is equal to or greater than a predetermined value. This is a group management control device for elevators.

(Embodiments of the invention) Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a schematic diagram of an elevator landing in an embodiment of the present invention. As shown in FIG. 2, in this landing, a device 15 for detecting the number of waiting passengers is installed near the ceiling 11 of the landing.
It is configured such that the number of passengers 13, 14 on the floor 12 within the detection range 16 can be detected. In addition, 17
is the landing door, and 18 is the curtain board.

Various types of devices such as ultrasonic sensors, infrared detection devices, and microwave-applied devices are used as the device 15 for detecting the number of waiting passengers, but the device 15 detects the number of passengers as shown in FIG. 5, which is approximately proportional to the number of passengers within the detection range. Any device that produces a proportional electrical signal, such as a voltage output, may be used, and if necessary, a plurality of them may be distributed to cover the entire hole.

FIG. 3 is a control circuit diagram in one embodiment of the present invention. In the figure, 85L is the hall operation panel installed at the 3111 hall (
The response light 21 is built in the destination button H5 on the 5th floor in 4) in Figure 1 and lights up when the destination button H5 is pressed, and 21 remembers that the destination button H5 on 5N has been pressed. It is a storage device. 22 is, for example, JP-A-50-636.
A selection device 23A to 23C for selecting a response elevator disclosed in Publication No. 42 etc. is for machines A@ to C, respectively, and a storage device 3 stores the output of the selection device 122.
7A to 37G are the outputs of the memory devices [23A to 23C, respectively, and are assignment signals for instructing operation for calls on the floors corresponding to the outputs. 29A to 29C are output signals of OR gates 35A to 35C, which will be described later, 26 is an OR gate, and 38 is a 2G output line connected to the reset terminal of the storage device 21. 24A~24G are AND gates, 25A~
25C is a destination indicator light indicating the position of the fifth floor in the destination indicators 5A to 5C. 30A to 30C are A to C@ respectively.
This is a signal from the car that is constantly input, and when the car arrives at the third floor and closes the door for departure, the third floor door close signal is no longer output. Reference numeral 15 indicates a detection device for the number of waiting passengers installed on the third floor landing, and reference numeral 28 indicates an H level when the sum of a positive polarity (+) input signal and a negative polarity (-) input signal is negative, and an L level when it is positive. This is a comparator.

Further, 35A to 35G are the or gates, and 368 to 36G are the 5th floor arrival signals issued when the A to C bow machines respectively arrive at the 5th floor. 59 is an operational amplifier, 60R
is a variable resistor for bias adjustment, which is connected to, for example, a -15V stabilized power supply. 61R to 66R are input resistances,
67R is a feedback resistor, for example 61R to 66R
Select 100Ω, 67R to 10Ω, and 60R to 40Ω.
It is adjusted to Ω. The other end of 65R is line H5R.

That is, it is connected to the output line 21, and when this output line 21 is at H level, it is floV, and when it is at L level, it is Ov. HIR, H2R, H4R, H6R are each
Destination buttons H1, H2, H4, H6 on the hall operation panel
is connected to a memory element of a circuit (not shown). Therefore, as shown in FIG. 6, the characteristic has a nominal bias of 2111 times.

The circuit shown in Figure 3 is for the hall operation 1liI of 31111i.
Although the destination button for the fifth floor of No. 4 is shown above, the same ones are used for the other destination buttons H1, H2, H4, and H6, and they are provided corresponding to each floor.

Hereinafter, the operation of the elevator group management control device configured as described above will be explained.

Now, assume that the user presses the destination floor button H5 for the 5th floor in 311i. The storage device 21 stores this, and the response light 851 lights up. The selection device 22 selects the response number 611 by taking into account various evaluation factors such as the position of each car, the situation of the call assigned to the direction 9, and the degree of congestion.

This method is known in various ways and is not directly related to the gist of the present invention, so a description thereof will be omitted here.

If A@ machine currently on the 1st floor is selected, storage device 2
3A memorizes it and issues an assignment signal 37A for A@machine. This instructs /Ill to stop at the third floor and go to the fifth floor. At the same time, the output of the storage device 23A is input to the AND gate 24A;
Since there is no one on the third floor, the third floor door close signal 30A is also input to the AND gate 24A, so the AND gate 24A outputs an output, the destination indicator light 25A lights up, and the destination indicator 5A of the A@ machine on the third floor is Indicates that you are going to the 5th floor. In this state, if the car of car A is also assigned to a call on another floor, a message indicating that the car will go to that floor is displayed in the same way. On the other hand, the output 37A of the storage device 23A becomes the reset signal 38 of the storage device 21 through the OR gate 26, the storage device 21 is reset, the response light H5L of the destination button H5 on the 5th floor on the 3rd floor goes out, and the selection device 22 prepares for the next call. When the car of car A arrives at 3N, picks up the passenger, and closes the door, the 3rd floor door close signal 30A disappears, so the AND gate 24
The output of A also becomes L, and the destination indicator light 25A goes out.

On the other hand, the passenger hall waiting number detection device 15 monitors the number of passengers as shown in FIG. 2, and outputs the output shown in FIG. 5. On the other hand, since the number of registered destination buttons on this floor is output from the operational amplifier 59 as the output voltage shown in FIG. If the number of registered destination buttons is more than 2, the output will be H''
becomes. In other words, if there are three or more pieces than the number of people in the hall due to a prank, etc., it is assumed that it is a prank, and the output 69 of the comparator 59 becomes H11. Note that it has no effect when the output 69 is LIT. When the car of A@ machine arrives at 511i, the 5th floor arrival signal 36A is issued and the or gate 35A is sent.
The output 29A becomes "H", resetting the storage device 21 and returning to the initial state. On the other hand, if there is one passenger on the third floor who presses the call for all floors as a prank, the output of the number of waiting passengers in the hall detection device 15 is +1V, but the output of the comparator 59 is about -2V, 5, and the output of the comparator 28 becomes °H''.

Therefore, the outputs 29A, 29 of the OR gates 35A to 35C
B, 2'9G are both 'H', orage-to 35A
Since the output 29A becomes H'', the memory device 23A is set. Similarly, the calls for the H1, H2, H4, and H6 circuits are also canceled. Furthermore, the hall lantern 2A on the third floor of Car A flashes to indicate the arrival of a car at the landing when Car A starts decelerating to stop at 31ili, but this is not related to this invention. Therefore, it will be omitted.

The present invention is not limited to the embodiments described above, and may be modified as follows.

(1) In the above embodiment, the explanation was given using an example of an elevator in service of 3 elevators/group with 6 floors, but it is a matter of fact that the elevator does not depend on the number of elevators, the number of floors, the speed, etc.

(2) The selection device shown in Fig. 3 [22 can be any device that determines the responding aircraft and issues a response command signal to the corresponding aircraft when the destination button is operated. Showa 50-63641. Any publication such as JP-A-50-63643 may be used.

(3) Although the above embodiment has been described in terms of a hardware configuration, it is possible to make the whole or a part (for example, the selection device 22) a microcomputer-applied device.

(4) In the above embodiment, when the answering machine is determined, the storage device 21
(FIG. 3), a reset signal 38 is output to erase the display of the destination button. For example, as shown in FIG. 4, the input section of the OR gate 26 (see FIG. 3) may be changed to The output signal 37A and the 3rd floor door open signal 52A, which becomes H when the A car arrives and opens the door when the destination button H5 is pressed (3rd floor), are input to the AND gate 51A, and the output 53A is sent to the OR gate 26. It is also possible to input the .

As a result, the destination button H5 on the third floor landing is kept lit until the A car arrives at the third floor and the door is opened, making the display easy for users to understand.

(5) In the above embodiment, a plurality of (for example, 42)
When a destination button is operated, only one elevator may respond at once, or a plurality of elevators may be distributed to respond.

〔Effect of the invention〕

According to the present invention described above, selfish behavior such as registering a large number of destination buttons and trying to board the earliest arriving car, which is a prank mode at most boarding halls, is detected from the relationship between the numbers, which is called the number of people waiting. The present invention can be canceled by pressing the button, and the influence on group management can be improved to such an extent that it can be practically ignored.Therefore, the advantages of the destination button method can be brought out, and an elevator group management control device that can earn the trust of passengers can be provided.
