Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator control device, and more particularly to a group management control device that selectively allocates hall calls to elevators.

It is preferable for control and usage that all elevators have the same service floor. However, for reasons such as building facilities or economic considerations, the service floors may be different depending on the elevators, such as basement floors or rooftop floors. Figure 1 shows a schematic vertical section of the building, with elevators A to C being 1
This is an example of a discrepancy in the service floors where the 10th floor is the service floor for D-F, B ₂ and B ₁ , and the 1st to 10th floors are service floors, and the underground B ₂ and B ₁ floors are only serviceable for 3 out of 6 vehicles. ing.

In such a case, for example, even if you register a descending hall call for the 9th floor to go from the 9th floor to the basement B _1st floor, the most suitable one from A to F will be selected and assigned service. It is not always possible to be assigned an elevator that can take you to the _B1 floor of the basement. For this reason, if you are assigned to an elevator that cannot service the B _1st floor underground, you will need to take that elevator and change to an elevator that takes you to the B _1st floor midway through (for example, the 1st floor).
Or, I had the inconvenience of having to re-register my call several times until I was assigned an elevator that could service the _B1 floor of the basement.

For this reason, in addition to the general hall call (hereinafter referred to as general call) button, special hall call (hereinafter referred to as special call) buttons for going to different floors such as B ₂ and B _1st floor are installed on the required floors. When a general call is registered, the service is assigned to the most suitable elevator from among all the elevators A to F that can service that floor, and when a specific call is registered, the service is assigned to a specific elevator specified in advance (e.g., Elevator D). Alternatively, a method has been proposed in which the service is assigned to the most suitable elevator from among a plurality of elevators (D to F) specified in advance.

However, if a general call and a specific call are registered together, two elevators will be allocated for each call, one for each call.
There are cases where unnecessary stoppages occur. For example, a general call is registered and assigned to Unit D, which can go underground.
After that, when a specific call is registered, it is assigned to machine E or F, which can go underground, and one machine ends up being idle. The same thing can be said when a specific call is first registered and then a general call is registered.

Therefore, if one call is registered and assigned to a specific elevator, a method may be considered in which no new assignment is made even if the other call is subsequently registered. However, in this method, even if a call is registered, there is no answer back, which gives a very strange feeling to waiting customers and may cause confusion.

An object of the present invention is to provide an elevator control device that can improve the above-mentioned problems.

According to the present invention, when either a general hall call or a specific hall call is registered and a specific elevator is assigned, the other hall call is automatically registered and the assignment to the other hall call is blocked. , and the answering light of the other hall call device is turned on.

Hereinafter, the present invention will be explained in detail with reference to an illustrated embodiment. In this example, the elevator is A,
There are 6 cars: B, C, D, E, and F. The service floors are A to C on the 1st to 10th floors, D to F on _B2 , _B1 ,
1st to 10th floors.

FIG. 2 is a circuit diagram of the A car that calculates the predicted waiting time for each floor, and the other cars have similar circuit configurations. In the diagram, UPAa and DNAa are relay contacts that close when Unit A is in ascending and descending operation, respectively, and H1
UAa to H9UAa, H2DAa to H10DAa are relay contacts C1 that close when the 1st floor up, 9th floor up, 2nd floor down, and 10th floor down hall calls are registered, and machine A is assigned to service.
Aa to C10Aa are relay contacts that close when a car call from the 1st floor to the 10th floor of car A is registered, F1
For UAb~F9UAb, F2DAb~F10DAb, Unit A ascends from 1st floor to 9th floor, descends from 2nd floor to 10th floor, respectively.
Relay contacts that open when the floor is descending (actual floor position or the nearest floor position where it can be stopped while traveling), A1UA1 to A9UA1, A2DA1 to A
10DA1, A1UA2 ~ A9UA2, A2DA2
~A10DA2, A1UA3 ~A9UA3, A2
DA3 to A10DA3 are analog adders that add and output input signals, and V _R is a voltage signal corresponding to the time required for the elevator to travel to the first floor.It varies depending on the traveling speed and floor distance, but generally it is 2 seconds. Any voltage signal corresponding to the degree may be used.
V _B is a voltage signal corresponding to the time required for a running elevator to stop each time in response to a call, etc. It is necessary for acceleration/deceleration, opening/closing of doors, getting on and off passengers, etc., and this also depends on the running speed etc. Although it varies depending on the situation, generally a voltage corresponding to about 10 seconds is sufficient.

Now, Unit A is on the first floor and relay contact F1 is on.
Suppose UAb is open circuit. At this time, the signal V _R is transmitted to adders A2UA2, A3UA2...
In addition, the output signal of adder A2UA2 is sent to adder A3UA2 through relay contact F2UAb.
The output signal of 3UA2 is sequentially transmitted to adder A4UA2 (not shown) through relay contact F3UAb and then to adder A1UA2. However, since relay contact F1UAb is open, no further transmission occurs. Therefore, adders A2UA2, A3UA2,
The output signals _{of .} On the other hand, if there is a call for the 8th floor in the car and a 2nd floor ascending hall call is assigned, then the signal V _B is relay contact H2UAa → adder A3UA1 → relay contact F3UAb adder A4UA1 → ... → relay contact F
7UAb→adder A8UA1→... (not shown), and the output signals of adders A2UA1 to A8UA1 become _VB . Furthermore, since the signal V _B is input to the adder A9UA1 through the relay contact H8UAa, its output becomes 2V _B , which changes from the relay contact F8UAb to the adder A9UA1 to the relay contact F9.
It is transmitted to UAb→...→adder A1UA1, and the output of adders A9UA1 to A1UA1 is set to 2V _B. However, since relay contact F1UAb is open,
No further information will be transmitted. Therefore adder A2UA
The output signals of 1, A3UA1, . . . become voltages corresponding to the number of stops between the elevator and the elevator.

Furthermore, the output signals of adders A1UA1 to A10DA1 and adders A1UA2 to A10UA2 are input to adders A1UA3 to A10UA3 and added.
Its output becomes signals n1UA to n10DA through relay contacts F1UAb to F10DAb. In the above example, relay contact F1UAb is open, so
n1UA, n2UA, n3UA, ... are respectively,
0, V _R + V _B , 2 V _R + V _B , ..., and therefore A
A voltage signal corresponding to the time required for the car to reach the first floor, second floor, third floor, etc., that is, the predicted waiting time, is obtained.

Figure 3 shows a circuit for descending to the 9th floor to select the elevator with the minimum expected waiting time from A to F in order to select a service elevator for a general call, and similar circuits are installed on other floors. There is. In the figure, CMA to CMF are analog comparators, (input voltage of terminal X) ≧ (input voltage of terminal Y)
The output signal is “1” when , and “0” when the opposite is true.
This is the result. r ₀ is a resistor, DA to DF are diodes, and constitute a minimum time selection circuit MIN. m9DA to m9DF are A to F units 9
This is a signal that becomes "1" when the service is selected to be optimal for descending the floor. Relay contact FULAb~
FULFb is a normally closed relay contact that opens when machines A to F are full or cannot be serviced.

The predicted waiting times n9DA to n9DF for descending to the 9th floor of the A car calculated by the circuit in Figure 2 and the 9th floor descent times n9DF of the B to F cars calculated by a similar circuit are connected to the minimum time selection circuit MIN shown by the chain line in Figure 3. Enter through FULAb~FULFb and select the minimum value and its elevator. For example, if the signals n9DA to n9DF are respectively 3V, 1V, 2V, 4V, 3V, and 2V, and the forward voltage drop of the diodes DA to DF is 0.5V, then
Toward the signal n9DB which is the minimum voltage (+V) - r ₀
-DB-n9DB current flows, only the diode DB becomes conductive, and the voltage on the commonly connected anode side, that is, the input voltage to the terminals X of the comparators CMA to CMF becomes 1.5V. Therefore, (input voltage at terminal X) > (input voltage at terminal Y) Comparator CMB
Only the output signal m9DB becomes "1", which means that car B has been selected as the elevator with the minimum predicted waiting time.

Additionally, if any of the elevators A to F is full and the relay contacts FULAb to FULFb are open, the signals n9DA to n9DF for that elevator will not be input to the minimum time selection circuit MIN, and will therefore be excluded from the minimum selection. It turns out.

Figure 4 is a circuit for descending to the 9th floor to select the elevator with the minimum expected waiting time from among pre-designated cars D to F in order to select a service elevator for a specific call. There are similar circuits on other floors.
In the figure, MIN' is the minimum term selection circuit in Figure 3.
This circuit operates in the same way as MIN, and other same symbols operate in the same way. That is, as in FIG. 3, the smallest elevator among the input signals n9DD to n9DF is selected and the corresponding output signals m9DD' to m9DF' are set to "1".

Figure 5 shows that when a general call occurs, the call is assigned to the elevator most suitable for servicing the call.
This is the holding circuit for the 9th floor descending general call that holds it. In the figure, m9DA to m9DF are the signals of cars A to F from FIG. 3 that become "1" when the elevator is selected as the most suitable elevator to service a general call going down to the 9th floor. hh9D is a general call signal that becomes “1” when the 9th floor descending general call is registered and becomes “0” when it is serviced, AND
1, AND2 is an AND element, OR1 to OR4 are OR elements, NOT1 is a NOT element, S9DA to S9DF
is a signal that becomes “1” when a general call for descending on the 9th floor is assigned to cars A to F. It is used to stop the elevator at that floor or to display guidance in the hall, and the relay contact H9DA _a ～H9
DF _a is opened and closed by this signal. In addition, l9D is a signal that becomes "1" only when assigned to a pre-specified D to F machine for a general call to descend to the 9th floor, and l9D' is a signal that becomes "1" only when assigned to a car from D to F specified in advance for a specific call to descend to the 9th floor. This is the signal from FIG. 6 that becomes "1" only when assigned to machine F.

Now, in order to service the 9th floor descending general call,
Unit A is optimal, that is, signal m9DA is “1”
Assume that a general call for descending to the 9th floor occurs at the same time (assuming that the output of the NOT element NOT1 is still "1"). At this time, both the two inputs of the AND element AND1 of the minimum term selection circuit MEA become "1", so its output also becomes "1", which is transmitted to the OR element OR1, and its output also becomes "1" (AND element AND
2 output signal S9DA is “0”). on the other hand,
A general call for descending to the 9th floor is registered, and the signal hh9
Since D is “1”, the AND element AND
The two inputs of 2 become “1” and the output signal S9
Set DA to “1”. Furthermore, AND element AND2
The output signal of “1” is OR element OR2, OR3
The output is set to “1” and the node element
In order to set the output of NOT1 to “0”, the signal m
9DA, that is, signal S9DA becomes "1" regardless of the output signal of AND element AND1 (OR element OR1
(because one input is “1”), the 9th floor down call is serviced by Unit A, and signal
Since 9D becomes “0”, signal S9DA becomes “1”
continue to hold. As a result of the above, the general call for descending to the 9th floor was assigned to Aircraft A. In addition, in the holding circuit shown in FIG.
When the signals S9DD to S9DF become "1", this is transmitted to FIG. 6 through the OR element OR4.

However, if a specific call to descend to the 9th floor has already occurred before the general call to descend to the 9th floor is generated, and it has been assigned to the pre-designated machines D to F,
In FIG. 5, since the signal l9D' from FIG. 6 is "1", the output of the OR element OR3 is "1", the output of the NOT element NOT1 is "0", and the minimum term selection circuit MEA~ AND element in MEF
The output of AND1 will never be "1". As a result, a general call for descending to the 9th floor was issued and the signal hh9D was issued.
Even if the signal S9DA to S9DF becomes "1", the signals S9DA to S9DF do not become "1". In other words, no elevator will be assigned to a general call going down to the 9th floor.

FIG. 6 shows a holding circuit for a 9th floor down designated call that, when a specific call occurs, allocates the call to the elevator most suitable for servicing the call from pre-designated cars D to F and holds it. In the figure, m9DD' to m9DF' are the signals of cars D to F from FIG. 4, which become "1" when the elevator is selected as the most suitable elevator to service the specific call for descending to the 9th floor. hh9D' becomes "1" when a specific call for descending to the 9th floor is registered, and becomes "0" when it is serviced.
A specific call signal, AND3 and AND4 are AND elements, OR5 to OR7 are OR elements, NOT2 is a NOT element, and MED' to MEF' are MEA to MEF in Figure 5.
This is a memory circuit that operates in the same way as .

A specific call for descending to the 9th floor is now registered and signal hh9
When D' becomes "1", the operation is similar to that shown in Fig. 5 above,
Signals S9DD' to S9DF' corresponding to machines D to F become "1". Then, the signals S9DD' to S9
When DF′ becomes “1”, the signal l is passed through the OR element 6.
It is conveyed in FIG. 5 as 9D'.

However, if a general call for descending to the 9th floor has already occurred before the specific call for descending to the 9th floor and has been assigned to the pre-specified machines D to F, then in FIG. 6, the signal from FIG. l9
Since D is “1”, the output of OR element OR7 is “1” and the output of NOT element NOT2 is “0”.
Therefore, the output of the AND element AND3 in the minimum term selection circuits MED' to MEF' never becomes "1".
As a result, a specific call for descending to the 9th floor occurred and the signal hh9
Even if D' becomes "1", signals S9DD' to S9DF' never become "1". In other words, the specific call for descending to the 9th floor will not be assigned.

Signals S9DD to S9DF in FIGS. 5 and 6 and S
9DD' to S9DF' all stop the elevator descending to the 9th floor, display guidance in the hall, and relay contacts H9DD _a , H9 as shown in Figure 2.
It closes DF _a , and it goes without saying that both may be connected in parallel.

FIG. 7 shows the hall call registration circuit for the 9th floor descending direction. In the figure, S9D _b is a normally closed contact for general hall call reset that opens when the elevator to which the 9th floor descending hall call (general call) is assigned stops for service, and S9D _b ' is the above-mentioned S9
Normally closed contact for specific hall call reset similar to D _b ,
B9D is a general hall call registration button installed in the elevator hall to register the 9th floor descending hall call (general call). It is a normally open contact that closes when pressed. B9D' is for specific hall call registration similar to B9D above. Normally open contact, HH9D, when the 9th floor descending hall call (general call) is registered.
This is a general hall call relay coil that is turned ON and turned OFF after being serviced. When this relay is turned ON, the signal hh9D shown in FIG. 5 becomes "1". HH
9D' is a specific hall call relay coil similar to HH9D above, and when this relay is turned on,
The signal hh9D' in FIG. 6 becomes "1". L9
D _a is the 9th floor descending hall call (general call) is D
~ _L9D'a is a regular contact that is assigned to machine F and closes when signal l9D shown in Fig. 5 becomes "1", and the hall call (specific call) in the downward direction on the 9th floor is assigned to machines D to F and is connected to the above-mentioned Signal l9D′ in Figure 6 is “1”
It is a normally open contact that closes when .

Now, if we register a general call in the direction of descending to the 9th floor, contact B9D will close, so -S9D _b -
Relay HH9 by circuit HH9D-B9D-
D turns ON and its contact HH9D _a closes, so
Thereafter, relay HH9D continues to be turned on by the circuit -S9D _b -HH9D-HH9D _a -. As a result, as explained in FIGS. 2 to 6, the elevator most suitable for the service is selected and assigned.

For example, if signal S9DA in FIG. 5 becomes "1" and is assigned to machine A, signal l9D
Since remains “0”, contact L9D _a does not close,
Relay HH9D' does not turn ON. However, for example, if the signal S9DE in FIG. 5 becomes "1" and is assigned to machine E, the signal l9D becomes "1",
Therefore, contact L9D _a is closed, and −S9D _b ′−
Relay HH9 is activated by the circuit HH9D'-L9D _a -.
D' turns on and its contact HH9D _a ' closes, so
-S9D' _b -HH9D'-HH9D' _a - Relay HH9D' is maintained in the ON state by the circuit. In other words, the specific call is automatically registered as a general call.

Furthermore, if a specific call in the direction of descending to the 9th floor is now registered, it is clear that the general call will now be automatically registered as a specific call, similar to the above general call.

In addition, from the point of view of answering back to waiting customers, it is not necessarily necessary for the other hall call to be registered as in the above embodiment. For example, if a specific elevator is assigned by one hall call, the hall call is registered in the assigned circuit, etc. Instead of transmitting the hall call signal to the control circuit of the other hall call, only the response light for the other hall call may be turned on.

As explained above, according to the present invention, the problems of the prior art described above can be improved, and there is no need to worry about giving a strange feeling to waiting customers and causing confusion.
