This is a latch circuit that is reset by the output of .

In FIG. 5, A1 to A4 are status signals issued when the first to fourth units are in a state where they can become dedicated, respectively.
1 is a memory circuit that is set when the output 43a of the detection device 4 is input and reset when the output 44a is input;
52A to 52D are dedicated selection condition detection circuits 53 are dedicated car number detection circuits, and 54A to 54D are gate circuits, which are opened by time signals 11 to t4 given to each car as shown in FIG. 6.

55A to 55D are dedicated car memory circuits, 56 is a hall call detection circuit that detects that a hall call has been registered, and 57 is a well-known hall call assignment circuit that allocates a car to a registered hall call. If output 57a is output and assigned to units 2 to 4 in the same way, output 57b will be generated respectively.
~57d is emitted.

Next, the operation of this embodiment will be explained.

The number of passengers getting off the car at a specific floor is detected by a passenger number detection device 1, and an alighting passenger number signal 1a is generated.

The subtracter 22 compares this with the constant signal 21a, and the signal 1a
If ≧signal 21a, an output is generated and the timer 23 is driven.

The gate circuit 24 is opened by the output of the timer 23, and the alighting passenger number signal 1a is input to the adder 25, added to the contents of the register 26, and stored in the register 26.

In this way, each time a car arrives, the timer 23 is reset, the number of alighting passengers is sequentially added, and the register 26
stored within.

If the timer 23 is in operation, the number of passengers getting off the train is added up through the gate circuit 24 even if the number of passengers getting off the train is less than the specified number.

This is to prevent variations in the number of people attending the meeting, and to account for the number of people who arrive late.

After the predetermined time has elapsed, the timer 23 no longer emits the output 23b, so the gate circuit 24 is closed and the number of passengers getting off the train is no longer added.

Further, the gate circuit 27 is opened by the output 23a, and the content of the register 26 which is the result of the addition up to that point, that is, the number of scheduled usages is outputted to the dedicated car number calculation device 3 as the output 27a.

At the same time, the output 23a of the timer 23 is sent to the operation timing detection device 4 as a start signal for a meeting, lecture, etc.

Further, the output 23a of the timer 23 is delayed for a certain period of time by a delay circuit 28 and output, and after the contents of the register 26 have been sufficiently output, the register 26 is reset to prepare for the next operation.

The output 27a of the expected number of customers detecting device 2 is input to the storage circuit 31 of the dedicated car number calculation device 3, and is compared with the constant signals 32a to 32c in the comparison circuit 33 to calculate the number of dedicated cars.

Now, the relationship between the magnitudes of the constant signals 32a to 32c is expressed as 32a<
If 32b<32c, when 31a≦32a, output 33a (zero cars), when 32a<31a≦32b, output 33b (one car), 3 2 b < 3 1 a
When ≦32c, output 33c (2 cars), 31a≦3
1a, output 33d (3 cars) is output to the dedicated car operating device 5.

When the output 33a is output, the operation timing detection device 4 and the memory circuit 31 are reset.

As a result, the car remains in normal operation and is not operated using a dedicated car.

The other output 23a of the expected number of customers detecting device 2 is input to the latch circuit 45 of the operation timing detecting device 4, and the latch circuit 45
is set and the gate circuit 43 is opened.

On the other hand, the passenger signal 1b from the boarding/alighting passenger number detection circuit 1 and the constant signal 41a are compared by a subtracter 42.

However, if a conference or lecture is currently being held, 1 b
<4 1 a.

At this time, the subtracter 42 does not produce an output.

Therefore, even if the gate circuit 43 is opened, it does not produce any output and does not affect the operation of the car.

Incidentally, when the number of passengers getting off at a particular floor is small and the comparator circuit 33 in FIG. 3 calculates that the dedicated car is in the zero range and outputs the output 33a, the latch circuit 45 is reset and everything returns to its initial state.

In other words, in this case, the number of people gathered is small, and the dedicated vehicle is not allocated and normal operation is performed.

Now that the meetings, lectures, etc. have ended, the number of passengers has increased, and 1
When b≧41a, the subtracter 42 outputs an output, and the gate circuit 43 outputs an output 43a to the dedicated car operating device 5.

As a result, the memory circuit 51 is set, and its output opens the selection condition detection circuits 52A to 52D.

Now, let us assume that the condition that can be used as a dedicated car is that the car is on standby, and that cars No. 1, No. 3, and No. 4 are on standby.

Further, it is assumed that the dedicated car number calculation device 3 emits an output 33c, indicating that the number of dedicated cars is two.

Therefore, the status signals AI, A3)A4 are input, and the detection circuits 52A, 52C, and 52D each issue an output.

Time t in FIG. If the output 43a is input to
A time signal t1 is first emitted.

As a result, the gate circuit 54A is opened, the dedicated car storage device 55A is set, and its output is input to the dedicated car number detection circuit 53.

However, since the designated number of dedicated units is two, no output is issued and the next dedicated unit is selected.

Next, the gate circuit 54B is opened by the time signal t2, but since the status signal A2 is not inputted, it does not indicate whether the second machine is dedicated.

Next, the gate circuit 54C is opened by the time signal t3, and since the state signal A3 is input, it outputs an output, the memory device 55C is set, and its output is input to the detection circuit 53.

Now, the detection circuit 53 detects that the number of dedicated circuits has become two and outputs an output, so the gate circuits 54A to 54D
are all closed, restricting Units 2 and 4 from being used exclusively.

The outputs of the storage devices 55A and 55C are sent to the hall call allocation circuit 57.
It is assigned only to the hall call of the specific floor detected by the hall call detection circuit 56, and outputs 57a and 57c are issued.

As a result, cars No. 1 and No. 3 go directly to a specific floor as if they are reserved for exclusive use, and do not respond to calls from other floors.

A dedicated car picks up passengers on a specific floor, responds only to car calls that the passenger has registered in the car, and when all car calls have been answered, reverses the driving direction and heads straight to the specific floor again, en route. Do not respond to calls on the floor.

This operation is repeated to transport passengers from a specific floor.

When a predetermined time has elapsed since the timer 44 of the operation timing detection device 4 was activated, the output 44a is generated and the latch circuit 45 is reset.

In addition, the memory circuit 31 of the dedicated car number calculation circuit 3, the memory circuit 51 of the dedicated car operation device 5, and the dedicated car memory circuit 5
5A to 55D are also reset and return to the initial state, the dedicated car operation is completed, and the car returns to normal.

The constants set in the constant storage circuits 21, 32, and 41 may not only be artificially given, but also may vary depending on the characteristics of the floor,
It is also possible to comprehensively judge the traffic situation of the entire building, the use of conference rooms and auditoriums, etc., and change the value each time.

Furthermore, by using modern advanced electronic technology such as computers, it is also possible to predict the number of attendees at meetings, lectures, etc. based on the increase in the number of passengers getting off the train.

Furthermore, the number of dedicated cars can be changed by predicting the time until the end of the dedicated operation from the expected number of customers and the number of dedicated cars, measuring the time from the start of the dedicated operation, and comparing it with the predicted time.

In the above embodiment, the timer 44 is used to issue a special operation end command, but the number of cars in which the passenger signal 1b is less than the constant signal 41a is counted, and when the number reaches a predetermined number, the end command is given. It's okay.

In the above embodiment, the dedicated car is selected from among the waiting cars. However, it is of course possible to predetermine the cars to be designated as dedicated cars, and select the specified number of cars as dedicated cars in order. It is possible.

In addition, the conditions that can be used as a dedicated basket are not limited to being on standby.
It is also possible to set it to other conditions, and it is also possible to comprehensively judge the traffic situation of the entire building and change the conditions each time by introducing a computer or the like.

Additionally, a conditional circuit can be provided to switch between dedicated cages.

As explained above, the present invention accumulates the number of passengers alighting from an elevator car to a specific floor, calculates the number of dedicated elevators sufficient to transport the cumulative number of alighting passengers, and, on the other hand, when the number of passengers reaches a predetermined number, The dedicated aircraft calculated above is placed in service on a specific floor to transport passengers from that specific floor.

As a result, at the end of a meeting, lecture, etc., a large number of passengers concentrated at a landing on a particular floor can be transported to their desired floor in a short time.
