Description

Description: TECHNICAL FIELD The present invention relates to an elevator call registration device that efficiently processes call registration between a plurality of elevator banks operating under group control.

[Prior Art] FIG. 3 shows two group management elevator banks (hereinafter, simply referred to as banks) in the same elevator hall constructed based on the conventional elevator call registration device disclosed in Japanese Utility Model Publication No. 50-68470. (Abbreviated as) is a circuit diagram of an elevator call registration device when installed, and is an example of a hall-up call on the second floor.

In the figure, (+) and (-) are the anode and cathode sides of the DC power supply, and (2
A) is the second floor ascending button on the A bank side, and (2B) is the second floor ascending button on the B bank side.

Hereinafter, the reference characters A and B are added to the end of each reference sign to distinguish between the A bank side and the B bank side.

(2H) is the 2nd floor landing call registration relay, (2Ha) ~ (2H
c) is the normally closed contact of the 2nd floor landing call registration relay (2H), (2Hd) is the normally closed contact of the 2nd floor landing call registration relay (2H), and (2R) is one of the elevators in the bank When the car decides to stop for the second floor ascending call, the response relay contact opens, and (2L) is the second floor ascending call registration light.

Next, the operation of the hall call registration device configured as described above will be described.

First, when the landing button (2A) of the A bank on the second floor is pressed, DC power supply (+) side-landing button (2A) -normally closed contact (2HdB) -response relay contact (2RA) -landing call registration A current flows through the relay (2HA) -DC power supply (-) side path, the second floor hall call registration relay (2HA) is energized, and the normally open contact (2HaA) of the relay (2H) closes and holds itself. . The normally open contacts (2HbA) and (2HcA) are also closed, so the DC power supply (+) side-normally open contact (2HbA) -2 floor hall rise call registration light (2LA) -DC power supply (-) side route Current flows through
The 2nd floor hall call registration light (2LA) of Bank A lights up,
In addition, the DC power supply (+) side-normally open contact (2HcA) -2nd floor landing call registration light (2LB) -DC current (-) side current flows, the second bank landing landing call registration light of B bank (2LB)
Lights up.

On the other hand, since the normally closed contact (2HdA) of the relay (2H) is opened, the function of the second floor hall up button (2B) of bank B is restricted while the relay (2HA) is energized.

Next, when the elevator of Bank A decides to stop at the 2nd floor landing call registration relay (2HA), the response relay contact (2R
A) opens and relay (2HA) deactivates.

Since the response to the hall call is outside the scope of the present invention, its detailed description is omitted.

As described above, in the conventional hall call registration device, when two banks A and B are arranged adjacent to each other or face-to-face in the same elevator hall, the waiting passengers of the elevator are registered in both banks and the elevator hall concerned is registered. Since it often happens that the passenger who arrives earlier arrives at the elevator, when the hall call registration is registered in one of multiple banks in the elevator hall on the same floor, the elevator that can answer the hall call for that floor Is configured to be limited to one.

[Problems to be Solved by the Invention] Since the conventional hall call registration device is configured as described above, while double registration of hall calls can be prevented, one bank operates all units. In some cases, the other bank operates group control operation only for half of the units, which may cause an imbalance in elevator service capacity between the two banks. In such a case, if only half of the units are in group management operation, that is, if the hall call registration is concentrated in the bank with the lower elevator service capacity, the operation of the bank with the higher capacity is restricted. However, there was a problem that the service of the entire building was extremely deteriorated.

The present invention has been made to solve the above problems, and is a case where interlocking control of hall calls is performed between banks, and the number of cars in group management operation of each bank is It is an object of the present invention to obtain an elevator call registration device capable of appropriately controlling the interlocking control of hall call registration when a balance occurs and preventing the deterioration of the elevator service of the entire building.

[Means for Solving Problems] An elevator call registration apparatus according to the present invention has a number of cars that are operating in group management between corresponding banks that perform interlocking control of hall call registration, and a predetermined condition or more. In case of unbalance, the registration restraint invalidating means for invalidating the hall call registration restraint that regulates the hall call registration of the other bank in the same floor and the same direction in accordance with the hall call registration of the other bank is provided. It is a thing.

[Operation] In the elevator call registration device according to the present invention,
The registration restraint invalidation means determines the unbalanced state of the number of cars in group management operation while performing interlocking control of hall call registration between banks, and based on the difference in elevator service capacity between the banks, It is determined to be valid or invalid for each case, and in particular, even when registration calls are concentrated in a bank with a low elevator capacity, it acts to suppress deterioration of service of the entire building.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a conceptual configuration diagram of an elevator call registration device of the present invention.

In the figure, (10) is a hall call registration means provided for each of a first elevator bank and a second elevator bank having different group management control systems installed in the same elevator hall, and (11) is for one elevator bank. Mutual input means for inputting the registration signal from the hall call registration means (10) to the other elevator bank, and (12) is the other when the registration signal for one elevator bank is input by this mutual input means (11). (13) is a hall call registration restraining means for restraining the hall call registration in the same floor of the elevator bank in the same direction to make registration impossible, and (13) is a predetermined number of cars in the group management operation of one elevator bank. The hall call that enables the hall call registration of the other elevator bank by invalidating the constraint by the hall call registration restraint means when Recording is a restraint invalid means.

Next, FIG. 2 shows an elevator call registration device embodying the conceptual configuration diagram of the present invention.

That is, this example shows an elevator registration call device in which two group management elevators X, Y, and Z are installed in two banks.

In the figure, contacts (Xa), (Xb), contacts (Ya), (Y
b), contacts (Za), (Zb) are normally closed contacts of the group management running detection relays (not shown) of Units X, Y, and Z, respectively, and are open during group management operation and group management If it is excluded from internal driving, it will be closed.

(HC) is a relay for detecting the number of operating units in the group management, and is activated when the number of operating units in the group management becomes 1 or less.
(HCa) is its normally open contact.

As in FIG. 3 showing the conventional example, the reference numerals A and B are added to the end of each reference numeral in the drawing to distinguish the constituent elements of the A bank from the constituent elements of the B bank.

Next, the operation of the above configuration will be described.

First, for example, if the X and Y units of three A banks are operating in the group management, the contacts (XaA), (XbA), (YbA) are open, so the group management operating number detection relay ( HCA) remains de-energized. Therefore, since the contact point (HCaA) is open and the contact point (2HdA) is open when the hall call of the A bank is registered, the constraint of the hall call registration to the B bank is effective.

If X and Y units of three A banks are excluded from the group management operation, the contacts (XaA) and (YaA) are opened,
DC power supply (+) side-Contact (XaA) -Contact (YaA) -Group control operation number detection relay (HcA) -DC power supply (-) side relay (HCA) is energized, contact (HCaA) Closes. Therefore, even if the landing call for Bank A is registered and the contact (2HdA) is open, the DC power supply (+) side-Board landing button (2B) -Contact (HCaA) -Contact (2RB) on Bank B
-Relay (2HB) -Direction of the DC power supply (-) side allows the hall call of Bank B to be registered.

In short, the elevator call registration device according to the present invention, when the number of cars in the group management operation in the bank becomes a predetermined value or less and one of the hall calls is registered on the bank side where the service capacity has deteriorated, the other That is, the landing call of the other bank can be called without restraining the registration of the landing call of the other bank so that the service of the entire building is not deteriorated.

In this embodiment, the X and Y machines in the A bank are taken as an example, but it goes without saying that the same operation is performed for the combination with other machines and the B bank. Furthermore, the number of banks in the bank is not limited to three, but a plurality of banks can be used, and the floor to be controlled is not limited to the second floor.

[Effects of the Invention] As described above, according to the present invention, a plurality of elevator banks are installed in the same elevator hall, a hall call registration means is provided for each of these banks, and hall calls of one elevator bank are registered. In this case, in a call registration device that restricts registration of hall calls in the same direction on the same floor of the other elevator bank to make registration impossible, the number of cars in operation of one elevator bank under management is less than or equal to a predetermined number. When it becomes, it became possible to register by invalidating the restriction of hall call registration of the other elevator bank, so if the number of cars in operation exceeds the prescribed number in any elevator bank, It is possible to prevent duplicate registration of hall calls, which can suppress the deterioration of the service capacity of the elevator and also to When the number of cars in operation falls below the prescribed number, it is possible to register the hall calls in duplicate, which allows waiting passengers to wait without waiting for a long time to arrive at the elevator bank car whose number has decreased. It is possible to use the car of the elevator bank that arrives early, and it is possible to effectively suppress the deterioration of the service capacity of the elevator.
