Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an elevator group management device.

Conventionally, in many group control elevators, the first car (usually one car) is selected from among the cars arriving at the main floor.
A method is adopted in which the car selected as the first car departs from the main floor in order.

In this system, in order to inform passengers of the first car and the other car (hereinafter referred to as the non-first car), the first car is equipped with a leading light that displays a message such as ``Departing first'' at the landing or inside the car. or light up the
The hall lanterns of non-starting cars are not lit, and only the hall lanterns of starting cars are lit (or blinking) to provide guidance.

This type of system guides passengers to the first car and allows many passengers to be carried at once.
When traffic on the main floor is relatively congested, such as when commuting to work in the morning, it is possible to operate with high transportation efficiency, and passengers can clearly see which car will leave first. This has advantages in terms of passenger service, such as being able to calmly select a car and board the car.

On the other hand, in modern group control elevators, when a hall call is registered, a car is immediately assigned to service the call, the hall lantern of the assigned car is lit, and the service car is displayed to the passengers waiting at the hall (hereinafter referred to as A method called "forecasting" has come to be adopted.

With this method, passengers can safely wait for the car to arrive in front of the predicted car because it is known in advance which car will serve them before the car arrives.

However, in a group control elevator that employs both of the above methods at the same time, when a car predicted for a landing call on the main floor arrives at the main floor, if multiple cars are on the main floor, Problems would occur because the above forecast would not necessarily be selected immediately for the first basket.

In other words, when selecting the starting car from among multiple cars, conventionally, for example, cars were selected in order from the lowest car number, or in the order in which they arrived at the main floor. If a car arrives at the main floor later than other cars, such as by answering a new intermediate call, the other car will be selected as the first car first, and the forecast car will be selected as the first car. Passengers who had trusted the forecast lights and waited in front of the forecast car landing area would not only arrive late, but also be unable to depart even after boarding the forecast car. It was doubly leading to poor service for passengers.

This invention has been made in order to eliminate the above-mentioned conventional drawbacks, and provides an elevator group management device that does not impair service to passengers waiting for the platform even if the forecast car arrives late at the main floor. With the goal.

The forecast flags W(1, 1) to W(4, 1) are "1" when the first to fourth cars are assigned to the up call on the first floor, and "0" otherwise. 0" (other call assignments are not shown).

FIG. 3 is a diagram showing the entire program of the group management device 1 of FIG. 1. In this Figure 3, 21
2 is an input program that takes input signals from the input circuit 5 into the RAM 3 and sets them; 22 is a known allocation program that allocates a car to service a hall call and sets allocation data and a forecast flag; This is a first car selection/cancellation program that selects and cancels cars and sets first order command data NEXT(1) to NEXT(4).

Further, 24 is an output program that outputs the set allocation data and advance command data via the output circuit 6. The programs 21 to 24 are executed in this order at a rate of once per second.

FIG. 4 is a flowchart showing the operation flow of the allocation program 22 shown in FIG.
7 is the operation procedure of the portion of the allocation program 22 that sets the forecast flag.

Further, FIG. 5 is a flowchart showing the operation flow of the first car selection cancellation program 23 of FIG. Reference numerals 30 to 47 in FIG. 5 indicate the operating procedure of the first car selection cancellation program 23.

Furthermore, Figure 6 is a circuit diagram of the hall lantern on the 1st floor of Unit 4. Among the car control devices 10 of Unit 4, the lighting circuit for the upbound hall lantern installed at the landing on the 1st floor also applies to other units. Consists of similar circuits.

51 in FIG. 6 is an assignment signal that becomes "H" when No. 4 is assigned to the first floor up call;
52 is a 1st floor car position signal that becomes "H" only when No. 4 car is on the 1st floor; 53 is an up direction signal that becomes "H" when No. 4 car is set in the up direction;
Reference numeral 54 denotes an advance command signal which becomes "H" when car No. 4 is selected as the advance car, and 55 denotes a periodic pulse signal having a waveform as shown in FIG. 7 for blinking the hall lantern.

This periodic pulse signal is set, for example, to have an "H" time of 0.5 seconds and a "L" time of 0.2 seconds.

In addition, 56 to 58 in Fig. 6 are respectively
The AND gate, 59 is the NOT gate, 60 is the OR gate, and 61 is the hall lantern installed on the first floor landing of Unit 4.

Next, the operation of the elevator group management apparatus of the present invention configured as described above will be explained. It is now assumed that Unit No. 1 is on the first floor (main floor), is set to face up, and the door is open. Furthermore, although Car No. 4 is assigned to the first floor up call and is forecast, it has just left the third floor and has not yet arrived at the first floor, and Car No. 1 is selected as the first car. do.

At this time, in FIG. 6, the first floor car position signal 52 of car No. 4 is "L", and the upstream direction signal 53 is "L".
Therefore, the output of the AND gate 56 is "L",
Since the output of the NOT gate 59 is "H" and the assignment signal 51 of the first floor up call of the No. 4 machine is "H", the output of the AND gate 57 is "H", and therefore the output of the OR gate 60 is "H". Becomes "H", 4
Hall lantern 61 on the first floor of the car is lit.

On the other hand, in the starting car selection cancellation program 23 of the group control device 1, the flag FLAG is set to 0 in step 30.
In addition, in step 31, the machine number 1 is initialized in the counter I.

In step 32, car No. 1 (I=1) has P(1, 1) = 1 and U(1) = 1, so it proceeds to step 34, where car No. 1 is the first car and NEXT(1) = 1. So,
Further, proceed to step 35, where FLAG indicating that there is a starting car is set to 1.

In step 36, the counter I increments the machine number by one as I=1+1=2, and in step 37, since I(=2)<5, the process returns to step 32 again. Since the No. 2 machine is not on the first floor, the process now proceeds to step 33, where the advance command data NEXT(2) of the No. 2 machine is set to 0.

In the same way, follow steps 32-33- for both Unit 3 and Unit 4.
Proceed to 36, advance command data NEXT (3), NEXT
(4) Both are set to 0, and in step 36 I=4+1=5
If it is set, after the determination in step 37, proceed to step 38.

Since FLAG=1 in step 38, the car proceeds directly to the exit, and steps 39 to 47 for selecting the starting car are not executed.

Next, when Unit 4 arrives on the first floor, 1 of Unit 4
Floor car position signal 52 is “H”, up direction signal 53
is "H", so the output of AND gate 56 is "H", the output of NOT gate 59 is "L", and the output of AND gate 57 is "L". Furthermore, since the preceding command data NEXT(4)=0, the preceding command signal 54 is also "L", and the output of the AND gate 58 is also "L". Therefore, the output of the OR gate 60 becomes "L", and the up hall lantern 61 on the first floor of the No. 4 machine goes out.

Now, it is assumed that before car No. 1, which is the starting car, departs from the first floor, car No. 2, following car No. 4, also arrives on the first floor. Immediately after the first car departs from the first floor, the first car selection cancellation program 23 selects the first floor car position data P(I, 1)= Since it becomes 0, the process proceeds to step 33, where the preceding command data NEXT(1) is reset to 0.

For Units 2 and 4 (I=2, 4), follow step 32
-34-36, and in the case of car No. 3 (I=3), steps 32-33-36 are followed, so the flag FLAG remains set to 0, and it turns out that the starting car is not on the first floor. This means that it has been detected.

In step 38, since FLAG=0, the process proceeds to step 39, where the counter I is initialized to 1.
In step 40, since Unit 1 is not on the first floor, P(1,
1)=0, so proceed to steps 41-42-40.

When I=2, in step 40, P(2, 1)
= 1, U(2) = 1, but since Unit 2 is not assigned to the 1st floor up call, the forecast flag Y
Since (2)=0, the process proceeds to steps 41-42-40, and car No. 2 is not selected as the starting car.

When I = 3, in step 42, the 3rd unit is 1
Since it is not on the floor, P (3, 1) = 0, so step 41
-42-40, and machine No. 3 was not selected as the starting basket.

When I = 4, in step 40, the No. 4 machine is on the 1st floor, is set for the up direction, and is assigned to the 1st floor up call, so P(4, 1) = 1, U(4) =
1, Y(4) = 1, and the process proceeds to step 43. Here, the advance command data NEXT(4) is set to 1, and the predicted No. 4 car is prioritized over the No. 2 car and selected as the first car. It turns out.

Here, the forecast flag Y(I) set in the allocation program 22 will be explained. Fourth
In the figure, when the forecast flag Y(I) is assigned to the up call on the 1st floor, the forecast flag Y(I) starts from step 12.
15 and is set to "1", and the forecast flag Y(I )
is held as 1, and when a departure command is issued and departure command data S(I) is set to 1, Y(I) is reset to 0.

If the up call for the first floor is not registered,
If there is no allocation forecast for Unit 4, that is,
If there are Units 2 and 4 on the 1st floor, Units 1~
Since the forecast flags Y(1) to Y(4) of the No. 4 car are all 0, the procedure proceeds from step 40 to step 41 to step 42 while I=1 to 4.

When I=5 and the process proceeds to step 44, the counter I is initialized to 1 in step 44. When I=2, Unit 1 is not on the first floor, that is, P
Since (1, 1) = 0, step 45 - step 46 - step
47-Proceed to step 45.

When I = 2, Unit 2 is on the 1st floor and is set in the upward direction, that is, P (2, 1) =
1. Since U(2) = 1, proceed to step 43, where the advance command data NEXT(2) is set to 1, and the No. 2 car, which has a lower car number than the No. 4 car, is selected as the first car. become.

When the No. 4 car is selected as the first car, the first car command data NEXT(4) is output by the output program 24 through the output circuit 6 as the first car command signal 54. Therefore, the advance command signal 54="H",
The output of the AND gate 56 becomes "H", so when the periodic pulse signal 55 becomes "H", the output of the AND gate 58 becomes "H", the output of the OR gate 60 becomes "H", and the upper hall on the first floor When the lantern 61 lights up and the periodic pulse signal 55 becomes "L",
The output of AND gate 58 is "L", OR gate 60
The output becomes "L" and the hall lantern 61 goes out.

In the end, while machine No. 4 was selected as the starting basket,
The hall lantern 61 will repeatedly blink.

When Car No. 4 departs from the first floor, in steps 30 to 37 of the first car selection cancellation program 23, I=
4, the process proceeds from step 32 to step 33, where the first car designation data NEXT(4) is reset to 0, and the first car designation is canceled.

As explained above, in this embodiment, even if the forecast car is delayed and arrives at the main floor, it is selected as the first car ahead of other non-forecast cars and the hall lantern is flashed. Therefore, passengers who were waiting in front of the forecast car can get on the forecast car without getting confused.

In the above embodiment, when a car arrives at the main floor, the hall lantern of the first car is made to flash, and the hall lantern of the car that is not the first car is not blinked. The point that the operations are made different is not limited to the above embodiment.

For example, if the first car can leave immediately, but the non-first car cannot leave until it becomes the first car, or the first car can leave 10 seconds after the door is opened, but the non-first car can leave the door. If you set a difference in departure time, such as not being able to depart until 20 seconds have passed after opening is complete,
Alternatively, various cases can be considered, such as hall lanterns, arrival gongs, and other information displays announcing the arrival of a car, such as when the first car is displayed at the start of deceleration, and the car that is not the first car is displayed at the beginning of the door opening. It will be done.

As detailed above, according to the elevator group management device of the present invention, even if a forecasted car arrives at the main floor late, it is selected as the first car with priority over other non-forecasted cars. As a result, it is possible to avoid deteriorating the service to passengers waiting in front of the forecast cart.
