Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] This invention relates to an improvement in a device for operating an elevator.

[Prior art]

Normally, an elevator registers a hall call using an up button or a down button installed at the hall, and uses this hall call to summon a car. Passengers who board the car upon arrival register a car call using a destination button installed inside the car, and drive the car to the desired floor. In this way, in conventional elevators, it is necessary to operate call buttons at the landing and in the car.

Therefore, in recent years, for example, Japanese Patent Publication No. 57-24310 has proposed a system that provides a destination button for directly registering the desired floor at the landing. This elevator has advantages such as improved group management performance and accurate waiting time display because there is no need to operate the destination button inside the car and the destination floor of the waiting customer can be known early on. There is.

However, even if you press the destination button at the landing, if you do not get on the car or get on another car, the car that has arrived will end up needlessly stopping, making the passengers in the car uncomfortable, or leaving the car at the landing. This may lengthen the waiting time.

Also, some people operate the destination button in a complicated way, so
The above phenomenon is likely to occur, and this is considered to be a drawback of elevators in which the destination floor is registered at the landing. In the above case, if the timing of floor registration (car call registration) for the car to stop is delayed by Jf, the disadvantage described in E will be alleviated, but on the other hand, the destination floor of the waiting customer mentioned at the beginning can be known earlier. The advantage disappears.

[Summary of the invention]

This invention is intended to improve the above-mentioned problem. Even if the destination call is registered as a car call, if no passengers board the car,
To provide an elevator operating device which reduces unnecessary stops of a car, eliminates discomfort for passengers in the car, and improves operating efficiency by canceling a car call for a destination floor operated on that floor. The purpose is to

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

[Embodiments of the invention]

In the figure, (1) is the elevator car, (3Al), (

In the above case, the output signal of terminal 3 is rHJ.
For example, using a well-known scanner and counter, the input signal is scanned by the scanner to form a time series pulse, and the counter is used to convert it into a time series pulse.
It can be constructed by counting. (78) is an OR gate,
('79), (80) are AND gates, (81) are OR gates
It is a gate.

Next, the operation of this embodiment will be explained.

Car (1) is currently on the 1st floor with the up direction, and a waiting customer who wants to go to the 5th floor at the landing on the 3rd floor can press the 5th floor destination button (3A).
5), the 5th floor destination button signal (3
b5) It becomes ldrHJ. At this time, the third floor car position signal 03 is rLJ, and the output signal of the AND gate θO is also rLJ, so the memory IC9 is set and the fifth floor destination call registration signal (3C5) becomes rHJ. This signal (3c5) may turn on a destination call registration light (not shown) built into the destination button (3A5) on the 5th floor. At this time, the first floor car position signal aη is rHJ
Therefore, the output signal of the OR gate is rHJ, and the upstream signal (8) is also rHJ, so the AND gate (
The output signal of 56) is rHJ. Now, the output signal of AND game) (60) becomes rHJ, and memo IJ (7
2) is set, its output signal becomes rHJ, and OR
The fifth floor car call registration signal cq, which is the output of the gate ('i'6), becomes rHJ.

Now, the 5th floor destination call registration signal (3C5) has a function as an upbound call signal for the 5th floor (details are omitted), car <
1) I-]: Ascend and be called to the third floor. Basket (
1) arrives at the third floor, the car position signal on the third floor becomes J3barHJ, so the output signal of AND gate θO becomes rH
J, the memory (c) is reset, and the 5th floor destination call registration signal (3c5) becomes "L".

Now, assume that because a passenger has boarded the car, the total number of passengers in car (1) is now two. Therefore, the small load signal (23b), which is the output signal of the load detection device Aya, becomes rn'' (
No-load signal (23a) is "L"), OR gate (78)
The output signal becomes VirHJ. On the other hand, the call registration signal (to) on the 5th floor is rHJ, so there are several plays (W).
The count value of is "l", the output signal of terminal 1 is "H", and the output signal of terminal 3 is "L". therefore,
The output signals of the AND game ('79) and (80) both become "L", and whether it is the output signal of the OR game (81) or the call cancellation signal (a), the signal remains as rLJ. That is, OR gate (78) and AND gate ('i'9
) and (80) constitute a comparison device, and the basket (1
) Compare the total number of passengers and the number of passengers. With this, AN
The output signal of the D gate (52) is rLJ, the output signal of the OR gate (66) is also "L", and the memory ('72
) is not reset, and the 5th floor call registration signal (c) is held at "H". When the car (1) ascends in response to the call registration signal (to) on the 5th floor and reaches the 5th floor, the car position signal QG on the 5th floor becomes "rn", and the OR gate (66)
The output signal becomes "H", memo 1 buff 2) is reset, and the call registration signal (to) on the 5th floor becomes rLJ. This means that the destination call for the 5th floor has been serviced.

However, suppose that the destination buttons (3A6), (3A)) for the 6th and 7th floors outside of the 5th floor were also manipulated as a prank at the landing on the 3rd floor, before the arrival of car (1). Although the circuit is not shown,
Since not only the 5th floor heel call registration signal) but also the 6th and 7th floor heel call registration signals (to) and @ become rHJ, the count value of the counter (77) becomes "3" and the terminal 3 The output signal of terminal l is rHJ, and the output signal of terminal l is rLJ.

If car (1) arrives at the third floor and one passenger gets on board, making the total number of passengers two, as mentioned above, the /J'i load signal (23b) becomes rI (J, so the OR gate (7
The output signal of 8) becomes rHJ. Therefore, when the door starts to close and the door close raw signal C1) becomes rHJ, A11D
The output signal of the gate (80) becomes rHJ, and the call release signal P15 becomes the output of the OR gate (81).
becomes. Now, the output signal t-t of the car position signal on the third floor (since Shima is rHJ, AND game) (52):
rHJ, and the output signal of OR game) (66) also becomes [H
J and the memory (72) is reset, so 5
The floor call registration signal G-8 becomes "L".

What I would like to emphasize here is that if the car call on the 5th floor has already been registered on another floor, the car call registration signal on the 5th floor will not become rLJ. For example, if passengers who have gathered from the 2nd floor have already registered a destination call for the 5th floor, the 5th floor destination call signal (205) will be "H" and the OR
The output signal of the game) (59) also becomes rHJ, and the memory (
71) is set. Therefore, memory (72
) is reset, the call registration signal on the 5th floor (
) does not become rLJ. That is, when a passenger who has registered a prank call gets on the train, the number of calls registered by that passenger that were not registered at other landings is divided by 1. Even if the car call is canceled as a prank call, there is a normal destination button inside the car, so by operating that button, the car call can be registered. Since this is a well-known operation, detailed explanation will be omitted.

FIGS. 5 and 6 show other embodiments of the present invention, and FIGS.
The figures and FIG. 3 will be used as is.

In the figure, % (2A) is installed near the entrance of the basket (1).
The light emitter of the passenger detection device emits the light beam (2Aa) that crosses the entrance/exit, (2B) the light receiver of the passenger detection device that also receives the light beam (2Aa), and (c) the light receiver (2B) is the light @
(25a) is a load increase signal that becomes "rn" when the output of the load detection device increases, (85) .

(86) is a delay circuit in which when the input signal is "L", the output signal becomes "L", and when the input signal becomes "ra", the output signal becomes rHJK after a certain period of time (for example, 2 seconds), (87
), (8B) are the same memories as above, (89), (
90) is an A N D gate.

Now, the 5th floor destination button (3A5) is being operated on the 3rd floor.
When the floor car call is registered and a passenger gets on board, the floodlight (
Since the light beam (2Aa) from 2 people) is blocked, the light beam cutoff signal I:24 becomes rHJ during that time, and the memory (88)
is set and its output signal becomes rHJ. This state continues until the output signal of the delay circuit (86) reaches 1&KrHJ for 2 seconds. When a passenger enters the heel (1), the load increase signal (25a) is set to rH by the load detection device 1t (1).
J, so the output signal of the AND gate (89) is "I
( ), the memory (87) is reset, and its output signal becomes "L". Therefore, the door closed raw signal Ql)
Even if becomes rHJ, the output signal of AND game (90) or the call release signal (a) is jt of "L". The output signal of the delay circuit (85) becomes "H" two seconds after the door close raw signal (al) becomes "January", and the output signal of the delay circuit (85) becomes "H".
) is set, and the outgoing signal becomes "town," but by then the door has closed and the door closed signal (c) has become "L," so it is the call release signal (a). becomes rLJ.

However, if no passengers boarded on the third floor, light @
Since the cutoff signal (c) does not become "H", the memory (8th) is not set. Even if there are passengers getting off the train and the light beam cutoff signal (c) becomes rHJ, the load increase signal (25a)
) does not become a town. In any case, the AND gate (
The output signal of 89) is "L", the memory (8)) remains set, and when the door close signal (21) becomes rHJ, the AND game) (90) is output. The call release signal (A) becomes rHJ, and the call registration signal (C) for the fifth floor becomes "L".

FIG. 7 also shows another embodiment of the present invention, and FIGS. 1 to 3 are used as they are.

In the figure, (251)) is the load boy signal that becomes "H" when the load for one person increases due to the load detection bag @Kan, (25c
) is a load increase signal that becomes "H" when the load for two or more people increases, (93) is an OR goo), (94) is a signal that counts the number of input signals that become rHJ, and the counted value is When the value is "1" or more, the output signal of terminal 1 becomes "H" and the count value becomes "
a counter whose contents become zero when the output signal of the terminal 3 becomes "H" when the value is 3" or more and the input signal of the terminal R becomes rHJ;
<95), (96) is an AND gate, and the input circle indicates that the signal level is inverted, and (97) is an OR gate.

When the 5th floor destination button (3A5) is operated on the 3rd floor,
The destination button signal (sb5) for the 5th floor is rHJ, so
The output signal of the OR gate (93) becomes "H", and if the counter (94) had been reset, the count value would be "1".
'', the output signal of terminal 1 becomes ra'', and the output signal of terminal 3 becomes rLJ. Here, when the car (1) arrives at the third floor and one passenger gets on board, the load boy signal (2
5b) becomes rHJ, and the load increase signal (25c) bar
Since it becomes LJ, AND gate (95), (96)
The output signal of b deviation is also "L", and OR goo) (9'
The car call release signal (a), which is the output of step 7), remains at "L".

However, before Kato (1) arrived on the 3rd floor, he operated not only the 5th floor destination button (3A5) on the 3rd floor, but also the 4th and 6th floor destination buttons (3A4) and (3A6). Then, the count value of the counter (94) is "3", and the terminal 3
The output signal of terminal "1" is rHJ, and the output signal of terminal "1" is rHJ.
Becomes LJ. Here, when one passenger gets on board, the load brat signal (251) only becomes "H" and the large load increase signal (25c) does not become "H", so the AND game) (
96) becomes the output rHJ, and the car call release signal (2)
becomes "H" and the 5th floor call is canceled. 2Å
If more than 100 passengers get on board, the large load increase signal (z5c) ld
rHJ, and output signal 1j of ANDgeni) (96)
rLJ, and the car call release signal becomes rLJ.

That is, the AAND gates (95) and (95) constitute a comparison device, which compares the number of passengers who have boarded the train and the number of registered destination calls.

When the number of registered destination calls is greater than the number of passengers who have boarded the train, it is determined that the call is a prank call, and the call is treated as a car call.

Note that Figures 1, 2, and 5 are diagrams and circuits related to the 3rd floor, Figure 3 is the circuit related to the 5th floor, and Figure 6 is only the passenger detection circuit going upward from the 3rd floor landing. Circuits on other floors may be similarly configured.

Further, although the number of cars (1) is one, it is also possible to easily control a plurality of cars.

Furthermore, if the passenger detection device uses a television camera and a pattern recognition device to count the number of passengers waiting at the hall and the number of passengers boarding the train, even more accurate detection will be possible.

〔Effect of the invention〕

As described above, in this invention, when a destination button provided at an elevator landing is operated, this is registered as a car call, and when it is detected that there are no passengers boarding from the elevator landing, the registered car call is Since the registration is canceled by the destination button operated by the passenger inside the car, it is possible to reduce the number of stops of the car due to unnecessary calls, eliminate discomfort for the passengers inside the car, and improve the efficiency of car operation. can be improved. Additionally, it is possible to cancel the car call for passengers who are already on board, thereby eliminating confusion.

In addition, since the car call is canceled when the number of passengers from the landing is less than the number of calls or destination calls, it is possible to more accurately prevent the car from stopping due to unnecessary calls.
