EP1418147A1 - Controller for elevator with multi-deck car - Google Patents

Abstract

The cage (4) for a passenger lift in accordance with the invention has two floors (5,6) one above the other and stops simultaneously at two floors. An escalator (7) may give passengers on the ground floor access to the first floor and the upper floor of the lift cage when the lift is at its lowest position (HH). There are lift call control panels (11) on each floor (1-40) of the building. A computer (8) is installed on the top floor with a Super Up Peak Unit control system (SU-PU). The computer receives inputs from sensors (9) on the lift drive motor (2) and comparison signals (13) and party line signals (14) from other lifts in the building.

Description

The invention relates to a control device with the features of The preamble of the appended claim 1, an elevator installation provided therewith having the features of the preamble of appended claim 11, and a method for controlling such an elevator system according to the Preamble of claim 12.

Such a control device, such an elevator installation, such Buildings and such a control method are known from US-A 5,086,883 known, to which express reference is made for further details.

a) Die Haupthaltestelle, dass heißt in der Regel der Gebäudeeingang (Lobby). Die Haupthaltestelle umfasst entsprechend der Kabinendeckanzahl der Mehrfachkabinen wenigstens zwei, meist die beiden untersten Haupthalte oder Haupthalteebenen. Die Haupthalte der Haupthaltestelle (Lobby) sind in der Regel mit Rolltreppen verbunden. Dort strömen täglich Tausende von Fahrgästen in und aus dem Gebäude. Für die Aufzugssteuerung ist hier das wichtigste Merkmal die immer gleiche Aufzugsposition beim Anhalten: Das unterste Deck hält in der untersten Haupthalteebene der Haupthaltestelle, also in der Regel der Lobby, an.

b) Die anderen Stockwerke, also beispielsweise die oberen Stockwerke oberhalb der Haupthaltestelle. Dort werden die Mehrfachkabinenaufzüge, bspw. Doppeldecker-Aufzüge, beim Zwischenstockverkehr so gesteuert, dass sie mit Vorteil gleichzeitig diejenigen zwei benachbarten Stockwerke bedienen, wo Passagiere ein- oder aussteigen. Der auf einem solchen Stockwerk wartende Passagier kann deshalb nicht wählen, mit welchem Deck er befördert wird.

All modern controls for elevator systems with multiple cabs, for example double cabs (double decker), aim to minimize the number of stops and thus the round trip time. With double-decker controls, the people getting on and off on two adjacent floors should therefore be served as simultaneously as possible. To accomplish this task, two zones must be considered separately for buildings equipped with multi-cabin elevators, for example double-decker elevators:

a) The main stop, which is usually called the building entrance (lobby). Depending on the number of cabins in the multiple cabins, the main stop comprises at least two, mostly the two lowest main stops or main levels. The main stops of the main stop (lobby) are usually connected by escalators. Thousands of passengers flock in and out of the building every day. For elevator control, the most important feature here is that the elevator position is always the same when stopping: the bottom deck stops in the lowest main level of the main stop, i.e. usually the lobby.

b) The other floors, for example the upper floors above the main stop. There, the multi-cabin elevators, for example double-decker elevators, are controlled for mezzanine traffic in such a way that they advantageously serve the two adjacent floors where passengers board or alight. The passenger waiting on such a floor can therefore not choose which deck to use.

Known control algorithms - see, for example, that from the EP 1 193 207 A1 known algorithm - offer more or less optimized Solutions for zone b).

The proposed invention fully optimizes control for the Trips from zone a).

For the timely "filling" of the building it is important that that of the Main stop starting elevators the "overlapping" stops (for example Avoid 13/14 and then 14/15). So far, this has been solved (see for example EP 0 301 178 A1) that on the lower main holding level only passengers boarding with the destination on odd floors and in the upper one those with the goals on straight floors. This Regulation applies both to the classic two-button controls and to the new destination call controls.

Other solutions have also been proposed. So in the EP 0 624 540 A1 a sensible elevator allocation by "preliminary information" proposed by the passenger. The passenger chooses to enter Elevators one of the locks, each lock having a floor zone assigned. The individual zones here consist of several floors.

Another solution is described in US Pat. No. 5,086,883, mentioned at the outset forms the preamble of the independent claims for destination call control. Accordingly, an elevator system, which is a double-decker elevator group includes, selectively divided so that about half the lifts belong to the even / odd subgroup and the second subgroup too odd / even. The multiple cabins will become dependent on the divisibility of the number of the target floor by the number of Cabin decks controlled per multiple cabin. With that every passenger should the use of the escalator is spared on both lobby floors, because it can always be assigned an elevator, regardless of the even number or odd number of the target floor. The single ones However, multiple cabins are always restricted Service "controlled, that means one of the cabin decks always stops in one even-numbered floor, the other on an odd-numbered floor. Correspondingly, the passenger is also assigned a specific one Destination, indicated by its destination call, currently the straight one Floor-serving cabin deck or one currently the odd Floor-serving cabin deck.

The known solutions have some disadvantages - the passenger must at least know what is called even and odd or then in which zone his target floor is located. With the zone locks, a regular one Building users do not have a behavioral stereotype in the same elevator group develop because different goals may be different Locks are to be used. Even the seemingly elegant solution dividing the elevator group into even / odd and odd / even subgroups hides the disadvantage that the waiting times for some passengers will be increased significantly.

The biggest problem arises when the floor names in the building do not match the numbering of the possible stops of the lifts. In such a case, the passenger's decision is correct Straightness / straightness of its target floor (general divisibility of the Target floor number due to the number of cabin decks) not with that which the control system uses based on the number of possible pairs of stops (Stop triples in triple cabins, etc.) considered. This Problem can also arise as soon as the elevator group or blind zones Express zones (that is, floors not served). Sometimes there are even several blind zones of different lengths and so can the choice of the cheapest stop pairs in relation to change even / odd or odd / even several times.

The object of the invention is to provide a control device, an elevator installation, a building as well as an elevator control of the in the preamble of independent claims mentioned type to improve such that the building filling with elevator passengers starting from the main stop goes faster.

This object is achieved by a control device with the features of claim 1, an elevator system with the features of the claim 11 and a control method with the features of the claim 12th

Advantageous embodiments of the invention are the subject of the dependent claims.

To control the operation with regard to zone a) is with the inventive solution for destination call control on the Main stop achieved a significant improvement. The controller uses according to the invention a dynamic conversion unit. advantageously, the conversion unit is adapted to the building layout.

The conversion unit or the control steps that can be carried out with it support the allotment and preferably also the Elevator allocation in an elevator group such that each elevator in the Distribution trip, starting from the main stop such as the lobby, only chooses the non-overlapping stops and accordingly the passengers allocated to the most suitable deck (and elevator). With that, the Turnaround times reduced, transport capacity increased, waiting times shortened. The passenger selects their destination floor, and on the display device, for example a display on the destination call registration device immediately the assigned deck (including the lower or upper lobby), the assigned elevator may also be displayed.

The advantage over previous solutions is that the passenger no decision about straightness / oddness (or other Divisibility by the number of cabin decks) of his target floor got to. Such a decision could be counterproductive. Another advantage can be seen in the fact that especially at "traffic peaks during peak traffic "passengers optimally on everyone Decks and, if necessary, elevators are distributed.

In the preferred embodiment, the term "dynamic" means that there is no static allocation of individual cabin decks Elevators to a specific floor group (e.g. even / odd) during an elevator ride there. The conversion unit can use it not only the problem of a discrepancy between the floor names in the building and a stop number within the Control, but also allows the grouping of the Passengers with even and odd destinations in one deck. Corresponding the function of the conversion unit, traffic peaks at from the lobby or similar main stop optimally starting (upward) journeys process, you could also call it different - for example SU-PU (Super Up Peak Unit).

An embodiment of the invention is explained below with reference to the accompanying drawings. It shows:

Fig. 3

is a schematic representation of an embodiment of an elevator control according to the invention for an elevator of an elevator group with double (decker) cabins.

In the following description as well as in the drawings are the numbering of floors or stops in quotes, to distinguish them from reference numerals.

Fig. 1 shows an elevator shaft 1 on the left, in which the respective by Elevator with double decker cabin indicated 4 floors are. To the right of this is the respective floor number in a first column GSNR specified. Next to the right is a possible one Control-internal floor numbering SINR specified. In another Columns are holding positions HPA of the double-decker cabin 4 (see FIG3) and provided with a possible stop number HNR. It is assumed that the corresponding elevator is on the floors "3" - "9" and "21" - "39" not operated. So these floors form the blind zones BZ or express zones that the elevator travels at high speed can happen.

The problem of the different numbering of the Floors from "building side" and "control internal" shown on the other hand. When looking at the illustration in FIG. 1, it can be seen that virtually any physical level in the building with multiple numbers can be designated. For example, the building floor is "40" (see above) as the passenger also knows) from the control point of view the "14" th served stop, but by the "15" th or also "16" possible stop of the double-decker cabin 4 can be operated. This must be taken into account by the control. The figure shows that the assignment of the lower cabin deck 5 to an odd Floor and the upper cabin deck 6 to a straight floor is not always practical. This would be the case with a destination call, for example the building floor "10" the double cabin 4 with the lower cabin deck 5 stop in the blind zone BZ of the unused floor "9".

2A and 2B are schematic representations of an elevator shaft shown. It is shown where the positions of the double cabin 4 could occur during a distribution trip at upward peak traffic. In both cases, for a better overview, only four passengers considered with the same driving wishes in both cases.

2A shows the previous solution with so-called "restricted service" (Even / Odd decision). It is believed that the passengers from the double decker lobby (floors "1" and "2" form the main holding levels) to the floors Want to drive "11", "12", "18" and "19". 2A are different Stopping positions of the double cabin of an elevator according to the state of the Technology shown when processing driving orders. So let's assume that at a main stop HH, which acts as a first main stop of floor "1" and, as a second stop level, floor "2" includes, passengers assigned to the destination floors "11", "12", "18" and "19" should be. The main stop HH is through the double roof elevator approached so that the lower cabin deck on the floor "1" stops and the upper cabin deck on the upper floor "2". The Both main levels "1" and "2" are by an escalator or the like connected, as will be explained in more detail below.

In the solution according to the prior art (Fig. 2A), the passengers enter the lower cabin deck with the target floors "11" and "19", those with the target floors "12" and "18" in the upper cabin deck. The elevator then stops at "11/12", taking the two passengers with it the destination floors "11" and "12" can get out at the same time. After that the elevator moves to position "17/18" to the passenger with the destination floor Let "18" get out in the upper cabin deck. Another short trip, which leads to position "18/19" is necessary to the passenger to be transported in the lower cabin deck to its target floor "19".

2B shows the possible stops for an elevator installation with a double cabin shown, which corresponds to the elevator car of Fig. 2A and the same travel orders to perform, but control them with a conversion unit SUPU is provided. This conversion unit divides the passengers who at the main stop HH your destination floor via a destination call registration device Enter 11, corresponding to those already assigned to the double cabin 4 Driving orders dynamically, with the possible allocations thereafter be compared which allocation the next trip the minimal stops.

The conversion unit SUPU optimizes based on that of the control module of the selected elevator delivered call situation the allocation of the passengers on the individual cabin decks. In this case, in the lower Cabin deck the passengers with the destination floors "11" and "18" and in the upper cabin deck the passengers with the destination floors "12" and "19" promoted. Thus, only two stops in the "11/12" and "18/19" necessary to transport all passengers to their destinations.

The advantages of the solution with the conversion unit SUPU (Fig. 2B) will be can be seen in a comparison with the previous double-decker controls with the so-called "Restricted Service" (shown in Fig. 2A), as described, for example, in EP 0 301 178 A1 or also in US-A 5,086,883 are known. On both pamphlets is for more details an exemplary hardware equipment one in question here upcoming elevator system expressly referenced.

When comparing the two representations according to FIGS. 2A and 2B, it becomes clear that that the use of the conversion unit SUPU the number of stops can reduce per round trip.

A concrete embodiment of a building serving a building according to FIG. 1 Elevator system with control is shown in Fig. 3.

3, an elevator shaft 1 of an elevator A is one of several Existing elevators group shown. A carrier 2 drives via a conveyor cable 3 one out of two in the elevator shaft 1 a common car frame arranged cabin decks 5, 6 formed Double cabin 4. It is assumed that the shown Elevator system in the building indicated at the far left in FIG. 1 at 41 Floors and with the interposition of blind zones BZ (in Fig. 3 not shown) served only a part of these floors of the building.

The distance between the two cabin decks 5, 6 from one another is chosen such that it corresponds to the distance between two adjacent floors, if you ignore the higher level "3". One in The main stop HH on the ground floor has a "1" floor value lower access L1 to lower cabin deck 5 and one on floor "2" upper access L2 to the upper cabin deck 6 of the double cabin 4. The two entrances L1, L2 are connected by an escalator 7.

The carrier 2 is e.g. in principle from EP-0 026 406 known drive control controlled, the setpoint generation, the Control function and the initiation of stop by means of a control device 8 takes place, which is designed as a microcomputer system. The control device 8 is connected to measuring and actuating elements 9 of the drive control. The control device 8 can also take on further tasks, as described and illustrated in detail in US-A 5,086,883 is. For example, there are also load measuring devices 10 with the control device 8 connected.

The floors are known, for example, from EP-A 0 320 583 Call registration device 11 is provided which has ten keyboards, by means of which calls are entered for trips to the desired destination floors can be. These are, as described in US-A 5,086,883 a data conductor 12 connected to the control device 8. The control devices 8 of the individual elevators in the group are above one first comparison device 13 and a known from EP-B-0 050 304 Partyline transmission system 14 known from EP-B 0 050 305 with one another in connection.

In the control device 8 there is a conversion unit by means of software modules SUPU formed in the control of the elevator system too minimizing the stops at one starting from the main stop HH Ride leads. The conversion unit SUPU has a second comparison device VE and a selection device AE.

At the main stop HH, for example, there is an area in front of the Escalator 7, where the paths to the two entrances L1 and L2 meet branch off, the corresponding call registration device 11. Here, a Enter the desired destination floor using the numeric keypad. With elevator A there are then possible assignments of passenger P. to the upper cabin deck 6 or the lower cabin deck 5. In the comparison device VE are already based on these two allocations travel orders assigned to the individual cabin decks with respect to one another the stop then necessary at the subsequent upward number is compared. The allocation that gives the least number of stops will be then selected by the selection device AE and passed to the passenger the display device 11a of the call registration device 11 is displayed. at In the example shown, an arrow "up" lights up for the upper cabin deck 6 on.

When comparing those to be carried out for a specific allocation Elevator stops are already the individual car decks of elevators A, B, C ... and the building structure, as can be seen from FIG. 1, are taken into account. This is done in the comparison facility for a specific allocation calculates at which of the holding positions HPA "1" - "16" the elevator car 4 would have to hold in this allocation. The corresponding stops are counted and with the holdings determined accordingly for the remaining allocations compared. Then the allocation that has the lowest number of total holdings, selected by the selection device AE and is displayed to the passenger P by the display device 11. Accordingly, In the example shown here, lamp "A" for elevator A.

The one that follows after the assignment and entry of passenger P. The trip is then minimized according to the allocation made Number of stops performed.
