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 in the boarding area that allows you to directly register the floor you want to go to.
-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 a drawback of elevators that register the destination floor at the landing.

[Summary of the invention]

This invention improves the above-mentioned drawbacks by confirming that the car has arrived at the landing and that a passenger has boarded the car, and then registering the car call on the destination floor, thereby reducing unnecessary stops of the car. An object of the present invention is to provide an elevator operating device that eliminates discomfort for passengers in a car and improves operating efficiency.

is the same memory as above, 53 is the input signal is "L"
When this happens, 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). A delay circuit 54 is an AND gate.

Next, the operation of this embodiment will be explained.

Car 1 is currently on the 1st floor, and if a waiting passenger who wants to go to the 5th floor at the landing on the 3rd floor operates the 5th floor destination button 3A5, the 5th floor destination button signal 3b5 becomes "H". At this time, the car position signal 13 is "L" and the output signal of the AND gate 31 is also "L", so the memory 36 is set and the
The floor destination call registration signal 3c5 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 point, as mentioned above, 3
Since the floor car position signal 13 is "L",
The output signal of the AND gate 43 does not become "H",
The car call registration signal 23 on the 5th floor does not become "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), the up direction signal 8 becomes "H", and the car 1 moves upward to the 3rd floor. be summoned. When the car arrives at the third floor, the car position signal 13 on the third floor becomes "H".
Therefore, the output signal of AND gate 43 is "H"
Therefore, the output signal of the OR gate 47 also becomes "H", the memory 48 is set, and its output signal 48 becomes "H".
a becomes "H". Now, the output signal of the AND gate 31 becomes "H", the memory 36 is reset, and the destination call registration signal 3c5 for the fifth floor becomes "L".

Here, when a passenger gets on the car 1, the light beam 2a from the floodlight 2A is blocked, so the light beam cutoff signal 24 becomes "H" during that time, the memory 51 is set, and its output signal becomes "H". . When a passenger enters the car 1, the load detection device 20 causes the load increase signal 25a to become "H", so the memory 52 is set and its output signal becomes "H".
Passenger detection signal 22 which is the output of AND gate 54
becomes "H". Now, the output of the AND gate 49 becomes "H", so the memory 50 is set, and its output is the car call registration signal 23 on the 5th floor.
becomes "H". The output signal of the memory 51 is “H”
When two seconds have elapsed since the start, the output signal of the delay circuit 53 becomes "H", the memory 51 is reset, and its output signal becomes "L". Therefore, the passenger detection signal 22 which is the output of the AND gate 54 becomes "L", and the output signal of the AND gate 49 also becomes "L".

As mentioned above, since the car call on the 5th floor has been registered, the door of car 1 begins to close, and when the door closing signal 21 becomes "H", the memories 48 and 52 are reset, and the respective output signals become "L". ”. Once the door has been closed, car 1 will again ascend and head towards the 5th floor.
When the car 1 arrives at the 5th floor, the 5th floor car position signal 15 becomes "H", so the memory 50 is reset and the 5th floor car call registration signal becomes "L".

If there were no passengers on the third floor, the beam cutoff signal 24 would not become "H".
The passenger detection signal 22 also does not become "H". 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", so the memory 52 is not set and the passenger detection signal 22 does not become "H". Therefore, the car call registration signal 23 on the 5th floor remains "L",
The car call is not registered and no unnecessary stop to the 5th floor is performed (unless a car call for the 5th floor is registered in car 1).

FIG. 5 shows another embodiment of the invention. However, FIGS. 1 to 3 will be 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. 61 is an OR gate, 62 counts the number of times the input signal of terminal C becomes "H", and when the count value is "1" or more, the output signal of terminal 1 becomes "H", and the count value becomes "H". 3" or more, the output signal of terminal 3 becomes "H", and when the input signal of terminal R becomes "H", the content becomes zero. By calculating the logical sum of the outputs of the well-known counter, ” signal is created. 6
3 is an OR gate, 64 and 65 are AND gates, 66
is an OR gate. Other than the above, it is the same as in FIG. 4.

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 61 becomes "H", indicating that the counter 62 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".
When car 1 arrives at the third floor and one passenger gets on board, the small load increase signal 25b becomes "H".
The outputs of the OR gate 63 and the AND gate 64 become "H", and the passenger detection signal 22, which is the output of the OR gate 66, becomes "H". . Now, as described above, the car call registration signal 23 on the 5th floor becomes "H".

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 62 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 signals of the AND gates 64 and 65 both become "H". ”, the passenger detection signal 22 is “L”,
The car call registration signal 23 on the 5th floor does not become "H". When two or more passengers board, the large load increase signal 25c becomes "H", the output of the AND gate 65 becomes "H", the passenger detection signal 22 becomes "H", and the car call registration signal on the 5th floor is output. 23 becomes "H". That is, OR gate 63 and AND gate 6
Reference numerals 4 and 65 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 destination calls registered is considerably larger than the number of passengers boarding the car, it is determined that a prank call is included, and the call is not registered as a car call.

Note that although Figures 1 and 2 show diagrams and circuits related to the 3rd floor, Figure 3 shows the circuits related to the 5th floor, and Figure 5 only shows the passenger detection circuit going upward from the 3rd floor landing, The circuit may be similarly configured.

Further, although the case where one car 1 is installed is shown, 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.

〔Effect of the invention〕

As described above, in this invention, a destination button is provided at the elevator landing, and when the car arrives at the landing,
And when it is detected that a passenger has boarded the car,
Since the destination call registered using the destination button above is registered as a car call, it is possible to reduce the number of car stops due to unnecessary calls, eliminate discomfort for passengers in the car, and improve car operation efficiency. can be done.

In addition, when the number of boarding passengers is close to or greater than the number of destination calls, the destination call is registered as a car call, so it is possible to accurately prevent the car from stopping due to unnecessary calls. .
