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 have boarded the arriving car register a car call using a destination button installed inside the car, and then 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, a destination button has been installed that allows you to directly register the floor you want to go to at the boarding point.
This is proposed in Publication No. 24310. This elevator has advantages such as improved group management performance and more 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 operate the destination button at the landing, if you do not get on the car or if you end up getting 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 result in longer waiting times. In addition, some people operate the destination button for fun, so the above phenomenon is likely to occur, and this is considered to be a drawback of elevators that register the destination floor at the landing. In the above case, if the timing of floor registration (car call registration) for the car to stop is delayed, the above disadvantages can be alleviated, but on the other hand, the advantage mentioned above of being able to know the destination floor of the waiting customer at an early stage can be improved. It disappears.

[Summary of the invention]

This invention is intended to improve the above-mentioned problem. Even if a destination call is registered as a car call, if no passenger gets on the car, the car call for the destination floor operated on that floor is canceled, thereby reducing the waste of the car. By reducing the number of stops and eliminating discomfort for passengers inside the car,
An object of the present invention is to provide an elevator operating device that improves operating efficiency.

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

42-47 are R-S flip-flops (hereinafter referred to as memory), 48 and 49 are OR gates, 50-6
3 is an AND gate, 64 to 69 are OR gates, 70
-75 is the same memory as above, 76 is an OR gate, 77 counts the number of input signals that become "H" among the input signals, and when the count value is "1" or "2", the output of terminal 1 A counter whose output signal at terminal 3 becomes "H" when the signal becomes "H" and the count value is "3" or more. For example, using a well-known scanner and counter, the input signal is scanned by the scanner. It can be constructed by converting it into a time series pulse and counting it with a counter. 78 is an OR gate, 79 and 80 are AND gates, and 81 is an OR gate.

Next, the operation of this embodiment will be explained.

Now, car 1 is on the first floor with an upward direction, and car 3
If a waiting customer who wants to go to the 5th floor at the landing on the floor operates the 5th floor destination button 3A5, the 5th floor destination button signal 3b5 becomes "H". At this time, the third floor car position signal 13 is "L" and the output signal of the AND gate 40 is also "L", so the memory 45
is set, and the destination call registration signal 3c5 for the fifth floor becomes "H". This signal 3c5 may cause a destination call registration light (not shown) built in the destination button 3A5 on the 5th floor to be turned on. At this time,
Since the car position signal 11 on the first floor is "H", OR
Since the output signal of the gate 48 is "H" and the upstream signal 8 is also "H", the output signal of the AND gate 56 is "H". Now AND gate 60
The output signal becomes "H", the memory 72 is set, the output signal becomes "H", and the car call registration signal 35 on the 5th floor, which is the output of the OR gate 76, is set.
becomes "H".

Now, the destination call registration signal 3c5 for the 5th floor has a function as an up call signal for the 5th floor (details are omitted), and the car 1 ascends and is called to the 3rd floor.
When the car 1 arrives at the third floor, the car position signal 13 on the third floor becomes "H", so the output signal of the AND gate 40 becomes "H", the memory 45 is reset, and the destination call registration signal 3c5 for the fifth floor is output. becomes "L".

Assume now that a passenger has boarded the car, so 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 20, becomes "H" (the no-load signal 23a is "L"), and the OR
The output signal of gate 78 becomes "H". On the other hand, 5
Since the floor car call registration signal 35 is "H", the count value of the counter 77 is "1", the output signal of terminal 1 is "H", and the output signal of terminal 3 is "L". Become. Therefore, AND gate 79,
All the output signals of 80 become "L", and the car call release signal 22 which is the output signal of OR gate 81
remains at "L". That is, OR gate 7
8 and AND gates 79 and 80 constitute a comparison device, which compares the total number of passengers in car 1 and the number of car calls. Now, the output signal of the AND gate 52 becomes "L", and the output signal of the OR gate 66 also becomes "L".
Therefore, the memory 72 is not reset and the 5th floor car call registration signal 35 is held at "H". When car 1 rises in response to the car call registration signal 35 on the 5th floor and reaches the 5th floor, the car position signal 15 on the 5th floor is activated.
becomes "H", the output signal of the OR gate 66 becomes "H", the memory 72 is reset, and the car call registration signal 35 for the fifth floor becomes "L". This means that the destination call for the 5th floor has been serviced.

However, at the landing on the third floor, 5 cars arrived before car 1 arrived.
Destination buttons 3A6, 3A7 for the 6th and 7th floors outside the floor
Let's also assume that it was manipulated as a prank. Although the circuit is not shown, not only the car call registration signal 35 on the 5th floor, but also the car call registration signals 36, 37 on the 6th and 7th floors.
also becomes "H", the count value of the counter 77 becomes "3", the output signal of terminal 3 becomes "H", and the output signal of terminal 1 becomes "H".
The output signal of becomes "L". If car 1 arrives at the third floor and one passenger gets on board, reducing the total number of passengers to two, the small load signal 23b becomes "H" as described above, so the output signal of the OR gate 78 becomes "H". ”. Therefore, when the door starts to close and the door closing signal 21 becomes "H", the AND gate 8
The output signal of 0 becomes "H", and the car call release signal 22 which is the output of the OR gate 81 becomes "H". Now, since the car position signal 13 on the third floor is "H", the output signal of the AND gate 52 is "H".
The output signal of the OR gate 66 also becomes "H" and the memory 72 is reset, so the car call registration signal 35 for the fifth floor 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 "L". For example, if a passenger boarding from the 2nd floor has already registered a destination call for the 5th floor, the 5th floor destination call signal 2c5 will be "H", and the output signal of the OR gate 59 will also be "H". , memory 71 has been set. Therefore, even if the memory 72 is reset, the car call registration signal 35 on the 5th floor remains "L".
It won't be. That is, when a passenger who has registered a mischievous call gets on the train, only the calls registered by that passenger that were not registered at other landings are canceled. Even if the car call is canceled as a prank call, a normal destination button is provided 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.

5 and 6 show other embodiments of the invention, and FIGS. 2 and 3 are used as they are.

In the figure, 2A is a light projector of a passenger detection device that is installed near the entrance of the car 1 and emits a light beam 2Aa that crosses the doorway, 2B is a light receiver of the passenger detection device that also receives the light beam 2Aa, and 24 is a light receiver 2B that emits a light beam. 2
25a is a load increase signal that becomes "H" when the output of the load detection device 20 increases; 85 and 86 are inputs. When the signal is "L", the output signal also becomes "L", and when the input signal becomes "H", the output signal becomes "H" after a certain period of time (for example, 2 seconds). Delay circuits 87 and 88 are similar to those described above. Memories 89 and 90 are AND gates.

Now, when the destination button 3A5 for the 5th floor is operated on the 3rd floor and the car call for the 5th floor is registered, and a passenger gets on board, the light beam 2Aa from the floodlight 2A will be blocked.
During this time, the beam cutoff signal 24 becomes "H", the memory 88 is set, and its output signal becomes "H". This state continues until the output signal of the delay circuit 86 becomes "H" two seconds later. When a passenger enters the car 1, the load detection device 20 outputs a load increase signal 2.
5a becomes "H", the output signal of AND gate 89 becomes "H", memory 87 is reset, and its output signal becomes "L". Therefore, even if the door closed signal 21 becomes "H", AND
Car call release signal 2 which is the output signal of gate 90
2 remains at "L". Two seconds after the door closing signal 21 becomes "H", the output signal of the delay circuit 85 becomes "H", and the memory 87 is set.
The output signal becomes "H", but by then the door has been closed and the door closed signal 21 has become "L", so the car call release signal 22 also becomes "L".

However, if there are no passengers on the third floor, the beam cutoff signal 24 will not become "H", so
Memory 88 is not set. Even if a passenger gets off the train and the light beam interruption signal 24 becomes "H", the load increase signal 25a does not become "H". In any case, the output signal of the AND gate 89 is "L", the memory 87 remains set, and when the door closed signal 21 becomes "H", the output signal of the AND gate 90 is the car call signal. The release signal 22 is “H”
Therefore, the car call registration signal 35 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, 25b is a small load increase signal that becomes "H" when the load for one person increases by the load detection device 20, and 25c is a large load increase signal that becomes "H" when the load for two or more people increases. Signal, 93 is an OR gate, 94 counts the number of times the input signal becomes "H", and when the count value is "1" or more, the output signal of terminal 1 becomes "H", and the count value is "3" or more. a counter whose contents become zero when the output signal of terminal 3 becomes "H" and the input signal of terminal R becomes "H";
96 is an AND gate, and the input circle indicates that the signal level is inverted. 97 is an OR gate.

When the 5th floor destination button 3A5 is operated on the 3rd floor, the 5th floor destination button signal 3b5 becomes "H", so the output signal of the OR gate 93 becomes "H", indicating that the counter 94 has been reset. if,
The count value becomes "1", the output signal of terminal 1 becomes "H", and the output signal of terminal 3 becomes "L".
Here, when car 1 arrives at the third floor and one passenger gets on board, the small load increase signal 25b becomes "H" and the large load increase signal 25c becomes "L".
The output signals of AND gates 95 and 96 both become "L", and the car call release signal 22, which is the output of OR gate 97, remains "L".

However, before Car 1 arrives on the 3rd floor, not only the destination button 3A5 for the 5th floor, but also the 4th and 6th floors are pressed on the 3rd floor.
If the floor destination buttons 3A4 and 3A6 are also operated, the count value of the counter 94 will be "3",
The output signal of terminal 3 becomes "H", and the output signal of terminal "1" becomes "L". Here, when one passenger gets on board, the small load increase signal 25b only becomes "H" and the large load increase signal 25c does not become "H", so the output of the AND gate 96 becomes "H".
The car call release signal 22 becomes "H" and the car call on the 5th floor is released. If two or more passengers get on board, the large load increase signal 25c becomes "H",
The output signal of the AND gate 96 becomes "L",
The car call release signal 22 becomes "L". That is, the AND gates 95 and 96 constitute a comparison device, and compare the number of passengers who have boarded the train and the number of registered destination calls. If the number of registered destination calls is greater than the number of passengers who have boarded the car, it is determined that this is a prank call and the car is not called as a car call.

Note that FIGS. 1, 2, and 5 show diagrams and circuits related to the 3rd floor, FIG. 3 shows the circuits related to the 5th floor, and FIG. 6 only shows 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.

Further, 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.

[Effects of the Invention] As described above, in this invention, when the destination button provided at the 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 registration is stopped. Since the registered car calls are canceled by the destination button operated by the passenger, it is possible to reduce the number of car stops due to unnecessary calls and eliminate the discomfort of passengers in the car. It is possible to improve the operating efficiency of Further, it is possible to eliminate the need to cancel the car call for passengers already on board, which may confuse them.

Further, since the car call is canceled when the number of passengers from the landing is less than the number of car calls or destination calls, it is possible to prevent the car from stopping due to unnecessary calls at any time and accurately.
