Method and device for controlling a group of cars

The invention relates to a method and a device for controlling an elevator group of several Elevators in a building for parallel operation are arranged.

In a building in which several cars are used for parallel operation controlled by a group control device are provided, numerous modes of operation are possible to cope with the traffic, for example, when the traffic is strong, then the individual cars are essentially uniform within the entire operating area distributed, while with weak or partially intermittent traffic, all cars are controlled in such a way that they are on standby in a basement or on the ground floor and only initiate a journey if

81- (Item 29782) -KoF

Travel commands are issued. There are now numerous other modes used. Suppose, for example, that one of the upper floors a call or call command is given in a building with many storeys when the traffic is weak. Since one of the cars on the ground floor is in standby position are, in such a case essentially responds to the fetch or call command, the one at the Service floor stop on the upper floor Passenger stand impatiently until the car departing from the ground floor over numerous mezzanine floors reached the floor.

It is therefore the object of the present invention to provide a method and a device for controlling a plurality of Specify cars that have multiple service floor stops operate so that these cars are in a suitable manner for a standby position on various Floors are distributed, which reduces the waiting time for passengers and a more efficient parallel operation the car group is enabled, albeit the number of operational cars is reduced, then the remaining operational or operational or available cars should be Cars be distributed in a suitable manner in the standby position on the various floors. It facilities should also be provided which, if the previously Set, split standby mode due to the operation of one or more cars is abandoned. Commands for a split standby position issued so that the unsuitable cars disregarded and suitable cars selected for the standby position on the predetermined floors can be.

This object is achieved in that numerous cars in a suitable manner at least three special floors including a ground floor are distributed so that each car on upward call commands from the storeys that are between one storey below the storey of the next upper car and the floor on which the particular car is provided, and that each car is on downward puff commands of the floors that are between one floor above the floor level of the next lower car and the floor on which the special car is provided.

It is also advantageous that one or more cars that are outside the ground floor on their special Floors are distributed in readiness position, return to the basement, vrenn the number of available or operational cars decreases so much that it is no longer possible to do all of them beforehand as planned in this state, the cars are distributed across the special floors and the ground floor in stand-by position to leave. Another advantage of the invention is that several standby zones, each of which consists of several adjacent storeys, including one of the special storeys, are predetermined, and that the commands for a distributed standby position for one of the special cars is deleted and for another suitable car be transmitted when the special or special Fahrkox'b moves away from its own standby zone.

The invention is explained in more detail below with reference to the drawing. Show it·

The control method described below avoids the disadvantages mentioned above. The entire operating area of a group of cars is intended for one

Zones are divided, and the cars are distributed to the respective zones for a standby position. The number the storeys contained in each zone is generally four to six, although they depend on the type of building and the operating conditions of the cars. The car provided in the standby position in each zone responds to call or fetch commands that come from the floors belonging to this zone.

FIG. 1 shows, for example, the distribution of the cars in the method that has already been developed six cars A-F intended to serve seven service-floor stops in a building with seven floors. the

309833/0397

seven floors are divided into three zones Zl, Z2 and Z3. The first zone Zl comprises the first and second floors. The second zone Z2 comprises the third, fourth and fifth floors. The third zone Zj5 comprises the sixth and seventh floors. It should be assumed that the traffic is weak or partially intermittent, and that cars A, B, C and F are provided in standby position on the ground floor in zone Zl, while cars D and E each, as shown, are in standby position in zones Z2 and Z3. The cars D or E provided in the second or third zone in the standby position can be at rest in one of the floors of the zones, depending on the previous operating conditions. It should be assumed, for example, that cars D and E are in the standby position on the third and sixth floors, respectively. If such a downward command comes from the fifth floor, then car D responds to such a command, since it is in the ready position in zone Z2. However, since car G is on the third floor, which is the bottom floor of zone Z2, car D must move up to the fifth floor. After picking up a passenger, he reverses his direction of travel, which is shown by an arrow a, in order to drive down to the destination floor, aasVim FahrköfD-Kat ig was saved by the passenger.

Such an operation will now be compared with a case in which the car E, which is provided in the standby position in the zone Z3, responds to the downward command from the fifth floor and travels in a downward direction, which is indicated by an arrow b. In the situation shown, the last operating mode is much more advantageous compared to the aforementioned operating mode, although it does not affect the

309833/039?

Problem of the zoning described later can be closed. Furthermore, an upward command from the fourth or fifth floor. In such a pail is the first mode of operation is not effective, since the car D, which is dependent on the down command from the fifth floor in the direction of the arrow a has moved down, move up again depending on the up command from the fourth or fifth floor got to. In contrast, the last operating mode is considerably more advantageous, since the car D is dependent on the upward command from fourth or fifth floor can go up even after the car E, depending on the down command from the fifth Projectile has moved downwards in the direction of arrow b. However, the last mode of operation is theoretical and only not suitable for practical use as it does not know the meaning of the presetting or zoning.

In the present invention, at least three particular floors are selected on which the cars stand by are distributed. More precisely, the first floor, which can be the basement or the ground floor, is the third floor, fifth floor and seventh floor selected as special floors, as shown in FIG. 2 .is shown. In this arrangement, the number of special floors is three. Cars A, B and C are respectively on the seventh, fifth and third floors in readiness position. The car E is on the first floor as first, dispatching car provided in standby position.

In the present invention, each car is further arranged to respond to upward commands from the floors that responds in the area of the storey below the

309833/0397

The lap position of the next upper car extends to the floor on which the particular car is located and that it is on Responds to downward commands from the floors in the area from the floor above the floor level of the next lower car to the floor where the special one Car is provided. If the car C, for example, as shown in FIG. 2, in the standby position on third floor is provided, then the upward and downward fetch command response zones of this car are determined in such a way that that it responds to upward commands from the upward fetch command response zone, i.e., to commands from projectiles coming from the fourth Floor, namely one floor level below the fifth floor, where the next upward car B is provided in the standby position, extends to the third floor, where the car C is located, and that this is on downward commands from the Down-fetch command response zone responds, i.e. to commands from the floors, those from the second floor, the one floor level is above the first floor, in which the next lower car D is provided in the standby position, up to on the third floor where the car is located. The command response zones of the individual cars are indicated by arrows in the Fig. 2 and indicated in the following table:

The arrangement of the cars and the determination of the command response zones in this way precludes inefficient operation as described above, and ensures very efficient operation of the cars on commands from all floors.

If in the present invention the direction of travel .von any one of the cars is designated, then one of its up and down command response zones becomes one of the commands can come in the opposite direction to the direction of travel of the car, deleted, and one of the downward and Up command response zones of the next upper or lower. The car in front of this special, moving car is expanded, to cover the deleted part of the command response zone. The extended command response zone of the next The car is of course extended to commands for a direction of travel that correspond to the direction of travel of the first mentioned Car opposite fet.

This change in the command response zones is explained in more detail below with reference to FIG. Suppose, for example, that a down command represented by a character V comes from the fifth floor and car B, responsive to this command, begins its downward journey. In such a case, the up command response zone from which reverse commands for car B can come, ie, in this case, up commands from the fifth and sixth floors, is deleted and the up command response zone of the next lower car C, which is in front of or below the Car B is, as shown, expanded. In Fig. J> , car B cannot respond to upward commands from the fifth and sixth floors, which were in the command response zone of car B, since the direction of travel of car B is downward. Therefore, it becomes the up command response zone

309833/0397

of the car C in the upward direction so expanded that it covers such fetch commands. As a result of this change in the command response zones, car C can make the stops on the fifth or sixth floor without increasing the waiting time for passengers, even if an order from fifth or sixth floor comes after a down command from the fifth floor.

If, in the present invention, any of the cars after the determination of its direction of travel and after the expansion of the one response zone of the car that is closest in the "forward direction" so that it covers the deleted zone of the moving car, as described above with reference to FIG has started its travel to another floor, then one of the downward and upward command response zones from which commands can come in the direction opposite to the direction of travel of the car ₄ and at least part of the other zone is canceled, and the downward and upward command - The response zone of the next lower or higher car behind this particular, moving car is expanded in order to cover the deleted part of the "other" zone. The command response zone of the next car is extended so that it responds to original commands in the direction of travel.

This change in command response zones is described below explained in more detail with reference to FIG. In Fig. 4, the car B responding to the down command from the fifth floor started its descent. In such a case, the reverse command for car B, i.e., here In the case of the downward command from the fifth floor, deleted, and the downward command response zone of the next upper car A, the is behind or above car B, as shown

309833/0397

represents, extended. In Flg. 4 the door of car B at the stop on the fifth floor was closed, and car B began its descent. Since this car B does not respond to a down command from a later floor than the fifth floor becomes the down command response zone of the car A expanded so that it covers such a fetch command. In the illustrated embodiment the cars are distributed so that they are on four special floors including the ground floor in the building with seven floors are distributed. The distance between these particular floors is small or the same as the distance between two storeys. However, in an actual elevator system, the number of floors is large, and there is a larger one Distance between these particular floors. Therefore, the descent of car B must be one of the special Floors to the next lower special floor go through numerous mezzanine floors and the command response zone changes when the car travels through these mezzanines.

If one of the cars does not respond to fetch commands from its command response zones because of travel in any direction can respond, then the command response zones of another, most suitable car must be extended. If one of the cars does not respond to fetch commands for other reasons not caused by its location can, then the command response zones of another, most appropriate car must be expanded in a similar manner. For example, if car B in Figure 2 is loaded at its maximum weight, then it becomes the up command response zone of car D expanded to cover up commands from the first to fourth floors and the down command response zone of car B is expanded in such a way that it

309833/0397

commands from the second and third floors covered while car C operated depending on the car cage commands that are stored in the car cage by the passengers.

In Fig. 5, a state is shown in which the car B, who, as shown in FIG. 4, has moved down, is at rest on the fourth floor, and in which the Car B has moved up to the fifth floor. Needless to say, the cars should be controlled so that their up and down command response zones despite possible changes in relative Layers of the cars are most suitable for their locations. Therefore it is provided that each car is on upward commands can respond from a fetch command response zone from the storeys from the storey below the storey position of the next Upper car extends to the floor where the particular car is provided, and that each car on Down commands from a down-fetch command response zone, which consists of the projectiles, which from a Floor above the floor level of the next lower car extends to the floor on which the special car is intended is independent of any changes in the relative positions of the cars. Therefore, with the present Invention changes the command response zones of the cars in a manner indicated by thin solid lines in Fig. 5 are shown. The following table applies to the new response zones:

These command response zones change sequentially with the operation of the cars _f so that they can be continuously maintained in a manner most suitable for a given situation. One problem is whether the first dispatch orders in de *. Car E or F should be fed, which are provided on the ground floor in standby 'position when the situation shown in FIG. 5 is present. However, no further reference is made to this as this problem does not concern the present invention.

In the above description, the term "floor on which a car is provided" was used to denote such a special floor to indicate that a car is in a position in which it will respond to a fetch command from the special floor can address. Even if, for example, the position of a car is very close to the third floor, then this will be Car considered as belonging to the position of the fourth floor if this car already has the has passed through the third floor, or when this car is traveling at a high speed and not on the third floor can stop even though its position is between the second and third floors.

Furthermore, the terms "next upper car" and "next lower car" are used for such cars those in the next upper and next lower layer in relation to a particular car (a car under consideration) lie. In the case of the car C shown in FIG. 5, no cars are provided below, since the cars E

309833/0397

and F cut off from the power supply and inoperative are. In such a case, the search direction is reversed, and that on the fourth floor Car B is considered to be the next lower car for car C. Under the next car above, this will be same understood.

The number of special projectiles is at least three in the present invention, as already described became. These particular floors should include the basement or ground floor. The term "basement" denotes generally the ground floor where the number of passengers is greatest and there are several cars there in standby position. In the present invention, however, the basement is one of the special floors is not necessarily the floor where the number of passengers is greatest. It can also be another suitable one Projectile in the vicinity of such a projectile can be selected.

The above explanations related to an improved standby device and the determination of the command response zones. However, this standby mode is not fixed, but flexible. So if one of the cars has driven into an unsuitable position, then the distributed »ready position commands for this car deleted and transferred to another suitable car.

For example, the car B in FIG. 4 is not included fifth floor, and this car is considered to be on the fourth floor as described above. In this In the situation, there is no car on the special floor in between or on the fifth floor in standby position, although cars A and C are each on the upper, special floor or seventh floor and on the lower, special

309833/0397

first floor or third floor are in readiness position. In such a case, it is not desirable to feed the distributed standby commands immediately into another car. The fifth floor Exiting car B can stop on the fourth floor and end its operation after the passengers have alighted. In In this case, the efficiency is higher when the car B drives back up to the fifth floor than when one another car is given a command to travel to the fifth floor. The same applies to other cars, the are provided on the special floors in standby position.

As already described above, the present invention is intended for an apparatus in which a plurality of cars in Readiness positions are distributed over at least three special floors, specify a facility that allows the distributed » Deletes standby commands for one of the cars and transfers these commands to another suitable car. The deletion of the distributed * standby commands for one of the cars and the transmission of such Commands to another suitable car, which is one of the features of the present invention, will be referred to below of Fig. 6 described.

In Fig. 6 a standby zone ZJ is provided, which consists of several adjacent floors, ie, aiis the floors from the second to the fourth floor, including the lower, special floor or the third floor. The distributed standby commands for the car C provided on the lower, special floor in the standby position are not deleted if the car C does not move out of the standby zone Zj5, which consists of the second, third and fourth floors. That's why

309833/0397

the car C moves back to the third floor and remains in the standby position on this floor after it has carried out all orders from floors of the standby zone Z3. On the other hand, when the car C depends from a command from the standby zone Zj5 then the distributed ^ standby commands for car B deleted. In this case, the efficiency is increased if the commands in another, suitable car can be fed. After the car C has left the ready position zone Z3, the Commands are fed into another, most suitable car so that it goes to the lower, special floor moves and remains there in standby position. To this end, a search operation is performed to find the car to determine who is present in the ready position zone Zj5 and can drive to the third floor. If such a If the car is found in zone Z3, then it is advisable to feed the commands into it. If such a Car is not found in the ready position zone Z ^, then the commands can be transferred to car E are fed, which is provided on the basement in standby position, so that it goes to the third floor. With this type of pre-setting or zoning, the desired deletion and transfer of the distributed » Readiness commands are carried out. However, this operating mode may lead to a situation in which no Car is provided in standby position on the basement floor if the remaining car F is used to transport Passengers go up to the upper floors or on the feed of distributed »standby commands appeals to.

In general, the requests for cars are in a building so that the drive request for a transport from

309833/0397

Ground floor, as essentially equivalent to other floors considered with the request for a transport between the mezzanine floors with the exception of the ground floor can be. That is why there should always be at least one car in standby position on the basement floor. It should therefore always be brought back to the basement floor at least one car of the distributed cars, if has reduced the number of cars in standby on the basement floor to a certain number, which can be zero or 1. Furthermore, the energy supply for the limit relay arrangement or the motor of the car, which is in 'standby position on the basement or on other, special Bullets are provided, generally interrupted after a predetermined period of time after being in this standby position have driven. The return of a stand-by device on one of the special floors, switched off car requires the excitation of its limit relay arrangement. Therefore only the car should Drive to the basement, whose limit relay arrangement is energized is. If the due to the disconnection of their limit relay arrangements in the standby position on the basement If the cars are not in operation, the distributed »standby commands should not be deleted in such a case even if the cars distributed to the respective standby zones are from these zones can move out.

In the case of the distributed standby mode of operation of the type described above, the operational failure of one or more cars due to maintenance and monitoring work, for example, leads to malfunctions or accidents

309833/0397

insufficient operation of the entire elevator system, and special measures must be taken to prevent such To cope with the situation. Therefore, if the number of operable cars decreases for these reasons, then the distributed standby mode must be appropriately modified so as not to service the passengers disturb.

This is described in more detail with reference to FIG. If one of the cars is inoperable then the elevator system will is controlled to establish a mode in which the cars E or F in Fig. 2 are excluded. At this Control mode, the desired operation can be realized except for the case where the number of the basement stop waiting for passengers is unusually high. In Fig. 8, the state is shown in which the Car E or F is excluded from the arrangement shown in FIG.

If two of the cars are inoperable, then

the car that is in standby at the lower, special Ge vccc / esenete car

shot ^ (car C in Fig. 2) in addition to car E or F excluded, and the command response zones of the remaining cars are changed as shown in FIG is. If three cars are inoperable, then the one in the open position will be added in the same way on the special floor in between Car (car B in Fig. 2) excluded. The result is shown in FIG.

In general, the travel requests for cars are in a building in such a way that the drive request for a transport from the basement to other floors is essentially as can be considered equivalent to the driving desire for a

309833/0397

Transport between the mezzanines, with the exception of the ground floor. There should therefore be several cars be available on the ground floor under all circumstances. On the other hand, through the distributed Standby system, the waiting time for any call or call commands can be reduced. Therefore too large a lower limit for the number of cars that are provided in the standby position on the basement floor should, not desirable, since then the operation of call commands coming from mezzanines deteriorates when the number of operable cars decreases. Therefore, the lower limit of the number of cars, which are provided on the ground floor in readiness position are carefully selected in order to achieve the best result.

In one application of the present invention to a group control system for controlling a group of cars with fewer than ten cars a good result can be obtained if the lower limit for the number of in The stand-by position provided on the basement floor is set to two cars.

In a group control system for controlling a Group of six cars, as shown in Figr 2, is setting the lower limit of the number of standby Cars provided on the basement floor are effective when two of the six cars are not in operation and if the car is excluded, the one on the lower, special floor in standby position. that is closest to the basement. This leads to the operating mode shown in FIG. The two

309833/0397

contrary requirements, which have been described above, can thereby be met in a suitable manner. A situation in which more than two cars are inoperable at the same time does not occur in practice. if however, should such a situation arise, the distributed standby mode in the in the manner shown in Fig. 10 can be changed.

In the following an embodiment of the invention Device explained in more detail with reference to FIGS. 11-16. For the sake of simplicity it should be assumed that a car group from six cars A, B, C, D, E and F in a building with seven floors to operate the floor stops from the first floor (ground floor) to the seventh floor. Although the basement and attic are not are considered, they should nevertheless be included in the service area of the cars. Although still no elevator system with express zones is described, the present invention can nevertheless be applied to such an elevator system be applied. Furthermore, the present invention

en

can be applied to other elevator systems with different arrangements.

There are two types of traffic, namely weak or partially intermittent traffic during the day and one Peak traffic, when the traffic is relatively heavy during the rest of the day. The number of special Floors to which the cars are initially distributed in standby position is appropriately selected, depending on the number of cars, the number of service floor stops, depending on the possible EiI zones and the properties or weights of the projectiles (both

309833/0397

for example, a heavy traffic due to offices of the management of a company). However, the following describes a case where in which the three cars are distributed so that everyone is in standby on the upper, special floor or seventh floor, on the intermediate, special floor or fifth floor and on the lower, special floor or third floor are provided, and that the other three cars are in standby on the ground floor.

Before the system is described in more detail, the names and modes of operation of the various relays are described in more detail explained. The relays and contacts with the suffixes A, B, C, D, E, and F in Figures 11-16 are for the cars, respectively A, B, C, D, E and F are provided, while the relays and contacts that do not have suffixes A, B, C, D, E and F are common for all cars A, B, C, D, E and F. To simplify the description, only the'dem Relays and contacts assigned to car A are explained in more detail. Furthermore, to simplify the illustration, only the circuits associated with cars A and F and the circuits associated with the first and seventh floors are shown. The cars B-E and circuits associated with the mezzanine floors are shown in phantom or not. However, it is obviously that appropriate circuits are suitable for this.

The operating relay 1OA is explained in more detail below.

This relay is energized when car A is controlled. This relay is not energized when car A is on Reason for a malfunction, repair and maintenance, accident or short circuit, for example

309833/0397

Control is ready for operation.

The relays 41A-47A for position detection are explained in more detail below.

The second number of these relays indicates the number of the floor. The position of the car is determined by the front Contactor detected on the car. If car A is at rest on one of the floors, it is that floor The corresponding position detection relay is energized, while the car A moves the one corresponding to the next floor Position detection relay is energized, at which the moving car A can stop. Therefore this situation changes depending the actual, physical position of the car and the travel speed of the car. For example the position sensing relay 44A is energized when the fourth floor car A is at rest. But when If car A is traveling up to the fourth floor, relays 45A, 46A and 47A are energized when the speed of car A is respectively low, medium and high. Furthermore, the excitation and disconnection of this position detection relay occurs necessarily with a suitable overlap. For example, the position detecting relay is 44A switched off after the activation of the position detection relay 45A, when car A moves up from the fourth floor to the fifth floor.

In the following the relay 4j5A is used for the lower, special Floor explained in more detail.

This relay is energized when one of the position sensing relays 42A, 43A and 44A is energized.

309833/0397

1) Selection of the cars that are processed on the ground floor to be in standby position on the upper, middle and to be on the lower floor.

To simplify the description, it should be assumed that a command for "weak" traffic is entered when all the cars are ready to run for controlled operation and are in the standby position on the ground floor. (In fact, however, "heavy" traffic changes to "light" traffic and the distributed standby arrangement is also used in "heavy" traffic. Therefore, the situation in which all cars are on standby at the basement is not general ). Under the above condition, relays 4lA - 4lF and relays 10A - IGF are energized in all cars. If there is "light" traffic, then car A is given the command to be the first to depart in the manner already initiated, and the first dispatch relay 70A is energized. The relays 1OH, ION and 1OL are each (Fig. 11) via the paths © - »IOD-4—» 10E-4 - »■ lOF-4—» coil from 1OH— > IT-2 -> 0, (T. ) --- »IOC-3 - * IOD-3 -> IOE-3 -> 10P-3 -> coil

Simultaneously relay contacts 67A-I and 67A-2 connect the relays 65A and 63A, so that the command cannot be given to car A, standby at the middle and lower to be a special floor. The relay contacts also lock 67A-4, 67A-5 and 67A-6 relays 67B, 67c, 67D, 67E and 67F, so that the other cars B-F are not

The relay HA is for upward travel of car A to the upper, special floor or seventh floor is excited. When the front contactor When car A reaches the level of the sixth floor, relay 46A and relay 57A (Fig. 12) are energized. Then the delay relay 57TA for the upper special floor is energized with a predetermined delay time (FIG. 12).

When the front contactor on car A reaches the seventh floor level, relay 47A is energized. The relay 2.1 A is switched off from its energized state due to the opening of the contact 47A-3 (FIG. 15). When the car A reaches the braking position for the seventh floor determined by the travel speed, the contact 13A-I of the relay 13A is closed.

upward travel is given. After stopping on that floor the car moves back to the seventh floor. It should for example assume that an up command is stored at the fourth floor landing before the front contactor on car A reaches the level of the fourth floor. In this case the relay 4UP is energized Once the front contactor on car A reaches the fourth floor level, relay 44A is energized to

Then the relay I5A energized and car A decelerates to stop at the fourth floor. After that for getting on and off the passengers required time the door is closed and locked again. Car A goes to the top floor, there the relay 21A is kept energized.

The following is the selection of the next car for a standby position on the middle, special floor described in more detail.

After the departure of car A to the seventh floor, the first dispatch orders for car A in the already suggested way deleted. The command for the first dispatch car is now given to car B.

At the same time, relay contacts 65B-I and 65B-2 lock the Relays 67B and 63B for a ready position of the upper and lower, special floor, so that the car B does not have the command for a standby position at the upper and lower, special floor must be entered. Relay contacts 65B-4, 65B-5 and 65B-6 lock the relays 65A, 65B, 65D, 65E and 65F, so that the remaining cars A, C, D, E and F are not commanded to be ready must be entered for the middle, special floor.

After a command for a standby position for car B at the middle special floor, relay 21B becomes for an upward travel selection

If then the front contactor on car B is the level of the fifth floor reached, then the relay 45B for the detection of the Location of the fifth floor excited. The relay 21B for a downward travel selection is switched off from its energized state, since contacts 45B-3, 45B-4 and 45B-5 are open are. When car B reaches the braking position of the fifth floor determined by its driving speed, then becomes contact I3B-I of relay IjJB for the braking position closed. The stop relay I5B is via the path (+) -> llB-2— ^

Coil of I5B— ^ IjJB-I »-21B-2> 22B-2 -» (£) ^ excites. The relay

I5B maintains itself through its contact I5B-I, and the car B is slowed down to stop at the fifth floor. Car B, moving up to the fifth floor, speaks to a call command from one of the mezzanine floors, if such a command is present during the upward journey. After stopping at such a floor, the car moves back to the fifth floor, as shown above of car A has been described in more detail. If there is still an operator request from a floor above the fifth floor is saved before the car B at the exit

Braking position of the fifth floor arrives, then the car B leads directly to this floor without stopping at the fifth floor. Suppose, for example, that an up call command is stored at the fourth floor stop by a passenger who wants to travel from the fourth floor to the sixth floor. In such a case, car B responds to an up call command from the fourth floor and stops at the fourth floor. After the storage of a car cage command with a driving intention for the sixth floor of the driving runs _r basket up to the sixth floor. When the front contactor on car B reaches the level of the fifth floor, then the relay 21B for an upward travel selection is not turned off even if the relay 45B for detecting the position of the fifth floor is energized, there is on

the stop relay 15B is not energized and the car B does not stop at the fifth floor even if the car B reaches the decelerated position of the fifth floor and the decelerated relay 13B is energized. Finally, the car B is braked in order to stop in the manner described above on the sixth floor when the front contactor on car B reaches the level of the sixth floor. After the car B has stopped on the sixth floor, the relay 22B is used for a descent selection via the path 0-11B-1

The relay 22B for the descent selection is made of the excited state through the opening of contacts 45B-1, 45B-2 and 45B-3 turned off. If the car B by its Driving speed reaches a certain braking position of the fifth floor, then the contact 13B-1 of the relay I3B closed for a braking position, and the car B is braked in the manner described above to reach the fifth floor to stop, the following is the selection of the next car for a standby position at the lower, special Floor described.

After the departure of car B to the fifth floor, the first dispatch orders for car B deleted in the manner already indicated. The car C the command for the first dispatch car is entered. Since the command continues to cars A and B was entered for a standby position on the upper and middle, special floor, these are Relay 67P and relay 65E each via the paths (Fig. 14)

The relay I5C keeps its state above its Contact I5C-I, and car C is braked to at Car E, moving up to the third floor, responds to a call command from the mezzanine on when such a command occurs during upward travel. After stopping at one of these On the 1st floor, the car moves back to the third floor, as was explained in more detail above with reference to car A. if Furthermore, a travel request for a floor above the third floor is stored before the car C is in the braking position the third floor arrives, then the car C drives directly without stopping at the third floor to such Floor, as explained in more detail above for car B.

From the above description it can be seen that the cars A, B and C in the standby position each on the upper, special Storey above the seventh storey, on the middle, special storey or fifth storey and on the lower, special one Floor or third floor are provided, and that the other cars D, E and F in standby on Are on the ground floor. This state is shown in Fig. 2, and the car D is in the standby position The command entered for the cars standing on the ground floor to be the first car to be processed.

Position on the upper, middle and lower, special floor and the cars provided on the ground floor explained in more detail. To the The order was given to car A to be on the standby position on the special upper floor. He is now on standby on the seventh floor. Therefore relays 16A, 47A, 57A, 57TA, 67A, 69A and 47TN are energized. To the Car B was given the command to be on standby on the special middle floor. He is in now Stand-by position on the fifth floor in a state in which it is ready to drive in any direction of travel. That's why, are the relays 16B, 45B, 55B, 55TB, 65B, 69B, 45UP and 45DN excited. The command was given to car C to be in the standby position on the lower, special floor. He is now in standby position on the third floor in a state in which it is ready to drive in every direction of travel. That's why are the relays l6c, 43C, 53C, 53TC, 63T, 69C, 43UP and 43DN energized. Furthermore, the command was given to car D to be the first car to be processed. He is now in standby position on the ground floor. This is why the limit relay 16D, the relays 4ID, 41E and 41F are used for position detection, the first dispatch relay 7OD and relay 4IUP energized. The relays 69D, 69E and 69F for readiness are switched off. Furthermore, the relay 4IP for a standby position in the hall, the relay 65P and the relay 67P are energized. The common limit relay 79P is switched off.

In the car arrangement described above, the call command response zone is of car A determined by the circles (Fig.15) O— »14A-2—» 47A-6—> 47DN-1—> 7DN and G—>

6UP determined. Thereby the up call commands are from the fifth and sixth floor in the up call command response zone of the next lower car C, so that these commands can be answered by car C. This state is

309833/0397

indicated by a thin line in Fig. J5.

When the front contactor on the car. B the plane the fourth floor after departure from the fifth floor for the transportation of the passenger to the fourth floor reached, then the relays 44B and 45B for detecting the position are energized and turned off, respectively, and the relays 44DN and 45DN for the common location are also energized, respectively and switched off. As a result, contact 44DN-2 is open in car B and contact 45DN-2 is closed, so that down call commands from the fifth floor are no longer answered by car B. In this case the

Circle 0 * 14A-2> 47A-6> 47DN-1 * 46DN-1 -> 45DN-1>

5DN in addition to the circles Q _ ^ 14A-2—> 47A-6— ^ 47DN-1—> 7DN and Q—> 14A-2— ^ 47A-6 —- * 47DN-1—? 46D »for ^D1 car A closed. In this way, the down call commands from the fifth floor are contained in the down call command response zone of the next upper car A, so that this down command is answered by car A. This state is shown in FIG.

If, for example, the car A provided in the standby position on the seventh floor continues up to his If full capacity is loaded with passengers who want to be transported down, then the relay 14A of the car is A energized, and its normally closed or normally closed contact is 14A-2 opened (Fig. 15). In this case, car A does not respond to any call commands. He has no call command response zone. Furthermore, since the normally closed or normally closed contact 14A-3 of the relay 14A is open (FIG. 16), none of the relays is for one common position excited by the relay of car A to detect the position. Therefore the previously energized relay 47DN shut down for a common location, and the circles

The up and down call command response zones of the The cars provided in the standby position on the special floors will be changed or restored,

purulent

depending on the determination of the direction of travel of a "car, dependent on the change in the position of such a car in relation to the other cars, and dependent whether one of the cars is fully loaded.

In fact, before such a change in the fetch command response zone occurs when two or more cars are in operation at the same time and when one of the cars is in standby on the basement floor. In other words, the fetch command response zones are continuously changed so that satisfactory operation can always be offered depending on the direction of travel, the position and the load on the cars _/ regardless of the initially distributed positions and the number of cars. This is evident from the above description with reference to FIG. 5, so that it does not have to be discussed in more detail.

As can be seen from the above description, the method according to the invention for distributing the cars is distinguished and to determine their command response zones by avoiding redundant operation by avoiding efficient Control of the car group is guaranteed and that the waiting time for passengers is reduced at the service floor stops wait.

309833/0397

3) Exchange of the distributed cars

When a down call command comes from the floor in one of the command response zones of car A, which is provided in the standby position at the upper, special floor, then car A departs from the seventh floor in the manner described above, depending on the stored command. As soon as the front contactor on car A is assigned to the upper, special floor, that is, if the relay 57A of the upper, special floor is held in the energized state, then the command for a standby position of car A on the upper, special floor is maintained, If However, the front contactor on car A is not assigned to the upper, special floor, that is, if & s relay 57A is switched off, then the commands for car A are cleared, and another, suitable car is the command for a standby position on the upper, special Floor entered instead of car A. According to the first condition, the command for a standby position on the upper, special floor is input to another car if such a car travels through the upper standby zone and the assigned relay for the upper, special floor is energized. According to the second condition, the first dispatch car, which is provided in the standby position on the basement floor, is given the command for a standby position on the upper, special floor if no car is provided in the upper standby zone and none of the relays of the upper, special floor is energized is. Car A, in which the commands for a standby position have been deleted, returns to the basement floor after the necessary controls have been offered.

309833/0397

Let us assume, for example, that a call or Pick up command at the stop on the seventh floor is stored by a passenger coming from the seventh floor wants to be promoted to the third floor. Since the car A is provided in the ready position on the seventh floor is, and there is a downward call command driving request to one other floor from the seventh floor is included in the command response zone of car A, relay 24A is over the circle (Fig. 15) 0 _ ^. 21A-4—> 31A-2—> 23A-1— *

Q excited. The relay 32A is energized to the call down command light to excite, which indicates to the passenger that the car A is ready for a descent. Simultaneously the door is opened. When the passenger then enters car A and a car cage command (3CA) for a travel request to the third floor stores, then the relay 22A

over the circle (+) - ^ HA-I— ^ 2IA-I> 3IA-1 »coil of

22A- »4IA-2 ^ 4lA-3> 4IA-4> 42A-1—> 42A-2— ^ 42A-3>

42A-4> 43A-1> 43A-2—> 3CA—>. 0 excited. After the to enter of the car required by the passenger, the door is closed and locked. The relay 12A will excited for the descent of car A to the third floor. When the front contactor on car A is the level of the fifth floor reached from the level of the sixth floor, as shown in FIG. 6, then the relay 45A is energized and the relay 46A is switched off. As a result, the relay 57A is turned off. The relay 57TA is turned off with a predetermined delay time. The standby relay 67A (Fig. 13) on the upper special floor will go out of its energized state switched off because the normally open contact 57A-1 of the relay 57A is opened, and because the normally closed or normally closed contacts 67A-5 and 67A-6 of relay 67A are closed, so that another suitable car is now ready for a standby position can be selected on the upper, special floor. It should

309833/0397

For example, it can be assumed that during this time the car P is in operation in the upper standby zone is like this in the Pig. 6 is shown. Then relay 57P is the special upper floor for the Car F energized and relay 67P of car F for a standby position on the upper, special floor

is over the circle Q ->lOF-6> 41P-6— ? 57F-2 ->63F-I—>

If there is no car in the upper standby zone, then the relay 67P for determining the standby position of the upper, special floor is switched off with a predetermined delay time after the switching off of the relay 67A for car A. By switching off the relay 67P, the relay 67D of the upper, special floor for the first handling car D, which is provided in the standby position on the basement floor, is via the circle (+) -> IOD-6— ^ 7OD-I -> 67P- 4—>63D-1—>65D-2—> coil of 67D—> 67E-4 ->. 67P-4— ^ 67A-6—> 67B-6— ^ 67Ct6— ϊ 10H-l-> Q energized. The car D is given a command for a standby position on the upper, special floor. He drives from the basement to the seventh floor.

The relay 69A is switched off for the car A in which the commands for a standby position have been canceled. The car A stops on the third floor depending on the car bkäfig-Be. After the passengers leave the car will have relay 22A via the circle (+) - j-lIA-l— ■ ^.

to cause the descent of car A to the ground floor.

309833/0397

Cars A and F are each in the standby position provided on the ground floor and on the seventh floor, as shown in FIG.

Car B is in the ready position on the middle, special floor or fifth floor. If this car B drives out of the middle safety zone with the fourth, fifth and sixth floors depending on calls from such a floor, then another suitable car is given the command for a standby position on the middle, special floor in the manner described above. This is entered in car C, which is provided in the standby position on the lower, special floor or third floor, and in the other cars.

The readiness commands for one of the cars that are in readiness at the upper, middle and lower, special floor will not be deleted if he stops the service floor on his own Safety zone served depending on an order from such a zone. The car moves back to the special floor back to be in readiness position on this floor after serving a travel request. However, if the special car depending on a command that requests a ride to a floor outside of one's own safety zone contains, drives out of its own safety zone, then a command for another suitable car is issued entered a standby position on the special floor, and the special car returns after the operation of the travel request back to the Grundgesehoss and is there on standby.

If there is still no car in standby position on

309833/0397

Ground floor is provided or if the number of on standby The cars present on the basement floor fall below a lower limit value, since they are in the standby position Exit the existing cars on the ground floor one after the other from the ground floor in order to avoid numerous passengers to move, then the readiness commands for the car or cars that are at the top, middle and lower, special floors are provided so that these cars can return to the basement. A command for a standby position on the special floors is sent to the rest of the car or cars entered.

• It should be assumed, for example, that the cars D, E and F provided in the standby position on the ground floor depart one after the other from the ground floor (cf. FIG. 2). Then the relays 41B, 41E and 41F of the respective cars D, E and F are switched off. The relay 41P is switched off. (Fig. 14). By opening the contacts 41P-1, 41P-2 and 41P-3 of the relay 41P, the relays 67A, 65B and 63c of the cars A, B and C provided in the standby position on the upper, middle and lower floors are switched off (Fig . IJ>), and the relays 69A, 69B and 69c of the respective cars A, B and C are switched off, so that these cars move to the ground floor. Simultaneously, contacts 69D-I, 69E-I and 69F-1 are closed by energizing relays 69D, 69E and 69F for cars D, E and F which have departed from the basement. A command for a standby position on the special floors is now input to these cars.

When the traffic is less and the orders from the ready areas of the cars for a certain period of time

309 8 3 3/0397

then the limit relay arrangement of each car is switched off after a predetermined period of time, and In this state, the cars are in the ready position. If one of the top, middle and bottom, special Floor in the standby position provided cars from its standby zone depending on a command drives out of this zone in a state in which all cars that are in standby position are provided on the basement floor are, the limit relay is switched off, then the standby commands for the special Car not deleted, and the particular car returns to the previously entered command after the operation of the drive request back to the special floor. If everyone is still on standby on the basement floor provided cars for serving a large number of passengers depart from the basement in a state in which the limit relays of all the cars provided in the standby position on the upper, middle and lower, special floor are switched off, then the dispatched cars are not given a command for a standby position to the special Shot entered. You return to the basement after serving the passengers.

It should be assumed, for example, that the cars provided in the standby position on the basement floor D, E and F, the limit relay arrangements are switched off in the state shown in FIG. Than are the limit relays 16D, 16E and 16F of those cars D, E and F are turned off and the common limit relay 79P is over

the circle (Fig. 14) © _ »69A-2—> 69B-2> -69C-2> 16D-2 ^

16E-2—3> 16F-2 -? - coil of 79P_ ^ Q energized. The relays 67A, 67B and 67c for cars A, B and C keep their state via contacts 79E-1, 79P-2 and 79P-J5 (Fig. 13). This state is maintained, although the

309833/0397

Drive cars out of their own standby zones.

Furthermore, the switching off of the limit relay arrangements of cars A, B and C, which are in standby position on the upper, middle and lower, special floor are, an opening of the contacts 16A-1, I6B-I and I6C-I of the respective limit relays ΐβΑ, 16B and 16C. In this way the relays 67A, 65B and 63c of these cars are not switched off. The commands for a standby position remain fed into these cars, even if all Cars, which are provided in standby position on the ground floor, depart from the ground floor, and the relay 41P is switched off.

As can be seen from the above description, a feature of the invention is that in a car system for Control of several cars, which are in readiness position on several special (not fixed and changeable) Floors are distributed, several standby zones, each of which includes several adjacent floors, lent one of the special projectiles is provided, and that the readiness commands for one of the special Cars are deleted and transferred to another suitable car when the particular car is out of its own standby zone. This arrangement is advantageous in that it downsizes an extensive operation and the cars can be effectively distributed.

4) Change of the distributed cars, depending on the number of operational cars

The distributed standby mode is changed in the manner described below when

309833/0397

one or more of the cars are inoperable.

The relays 1OA, 1OB, IOC, IOD, 1OE and 1OF are switched off, if the respective cars A, B, C, D, E and F are inoperable, for example due to repair work and an inspection, may be based on a malfunction or an accident. That shown in FIG Relay 1OH for operation with three cars is energized when three of the six cars for operation to be ready. Similarly, relays 1OM and 1OL are energized for four and five car operation, respectively, when four and five cars out of the six cars are ready for operation. That's why everyone is these relays 1OH, 1OM and 1OL are energized even if one of the six relays is switched off for an operating state. the Relays 1OM and 1OH are energized and relay 1OL is switched off when two of the six relays have an operating status are switched off. The relay 6L is only energized when three of the six relays are switched off for an operating state. Furthermore, all of these relays 6L, 6M and 6H are switched off when four of the six relays are switched off for an operating state are.

In Fig. IJ> the contact 10L-1 of the relay 1OL is closed for operation with five cars depending on the excitation of this relay 1OL, and the command circuit for a standby position on the lower, special floor is switched on when at least five of the six Cars are operational. Contact 10M-1 of relay 1OM is closed depending on the excitation of this relay 1OM. The command circuit for a readiness position of the middle, special floor is excited when at least four of the six cars are ready for operation. In a similar way it is

309833/0397

the contact 10H-1 of the relay 1OH depending on the excitation this relay 1OH is closed, and the command circuit for a readiness position of the upper, special floor is energized when at least three of the six cars are operational.

For example, if four of the six cars are operational are, then the command circles for a readiness position of the upper and the middle, special Floor excited, so that optionally one of the cars the command for a standby position on the upper, special Floor is entered, so that the command for a standby position at the middle, special floor is entered, and so that finally the other two cars are given a command for a standby position on the ground floor.

In other words, if at least two cars are in the ready position are provided on the ground floor despite a short circuit in one of the other cars, then the distributed standby arrangement not changed. if However, if this condition is not met, the standby commands are issued for the cars provided in the standby position on the middle floor one after the other cleared, starting with the car closest to the ground floor to preferably ensure that the required cars are on the ground floor.

Depending on the switch-off of the relay for the operating condition of one of the cars A, B, C, D, E and F, contacts lOA-5, lOB-5, lOC-5, lOD-5, lOE-5 or lOF-5 (Fig. 16) opened so that the relays for a common position, which are excited depending on the stop position of the car,

309833/0397

sr

cannot be excited. Therefore, this car cannot have a standby zone. If the The number of operational cars decreases and the standby commands are deleted accordingly, where for example the ready position commands must first be deleted for the car provided in the standby position on the lower, special floor (Fig. 15) then the car in the standby position on the third floor returns to the ground floor, to be ready there now. In this situation, up call commands are from the third and fourth Floor contained in the upward call command response zone of the first handling car, which is in standby position is provided on the basement. Furthermore, downward call commands are from the third and second floors in the downward call command response zone of the car, which is in standby position on the middle, special floor or fifth Projectile is provided, as shown in FIG. In the case of weak or intermittent traffic, at least one car is always provided in the standby position on the hall or basement floor, and at least two cars are provided arranged in the standby position in the special floors, as shown in FIG. To this In this way, the passengers can be served by the cars without any significant waiting time. It will be an economical one and satisfactory operation offered.

The above description related to a change in the distributed standby mode, depending on the number of operational cars, if however one of these cars is not ready for operation in the above operating mode, then this car is switched from the ready position in the manner described above

309833/0397

closed and the distributed standby mode is changed depending on the number of operational cars.

In the case of heavy traffic, the number of passengers who want to be carried up is essentially the same the number of passengers who want to be carried down. The mode of operation for such "traffic is explained in more detail below.

If the traffic changes from "weak" to "strong" with an increasing number of passengers, then will the relay IT switched off and the relay BT energized. The relay 1OL for operation with five cars is open Reason for the opening of contact IL-I of relay IT (Fig. 11) switched off while the relay 1OH for an operation with

and

three cars ^ the relay 1OM for operation with four Cars are kept energized by contact BT-2 of relay BT. As a result, contact is IOL-1 of the relay 1OL opened (Fig. 13) and the command circuit for a standby position the lower, special floor is switched off. For example, although the command circle for a The readiness position of the lower, special floor was switched off, for example, the command circle for a standby position of the upper or middle, special floor can be switched off, and the special

Bullets for a standby position can easily be gees

will be changed. To put it more precisely, ν the car (FIG. 9) provided in the standby position on the fifth floor can be brought to the fourth floor to be there in standby. position to be. It is also possible to bring the car provided in the ready position on the seventh floor (FIG. 10) to the fifth or sixth floor in order to be there in the ready position. At least one of the cars

309833/0397

is always on standby on the ground floor, as provided in the case of weak or intermittent traffic is so that this car can work together with another car, which is a command for a permanent standby position is entered on the upper, special floor. A command for a standby position on the middle, special floor can always be given to another car, so that it responds to call commands from these command response zones and to car cage commands. That's why everyone speaks the car on forward call commands from the zone which, in νβΗ of the direction of travel of the car, leads to the position of another, previous car is enough, the one in the same direction moves if such a previous car is available. On the other hand, if there is no previous car in the forward direction such a car is provided, then the last car speaks to forward call commands from the floors in its forward direction and reverse call commands for another car in the opposite direction Direction behind the floor next to this car. For example, if one of the cars goes up to the second Floor moves and when the next car behind the fifth floor moves to the sixth floor, then the first speaks Car on upward commands from the second, third, fourth and fifth floors. On the other hand, if one of the cars moves up behind the fifth floor to the sixth floor, then there is no previous car in the same Direction provided. Another car, the position of which is closest to this in the opposite direction, moves on down behind the fifth floor. The first-named car speaks on upward commands from the floors above and including the sixth floor. He continues to respond to downward commands from the floors above and including the sixth floor. Therefore changed

309833/0397

the car, its direction of travel and returns to the basement back when there are no forward call commands from its own command response areas in spite of the generation of other forward call commands are present (in other words, 'if such commands are in the command response zones of the preceding Contained in the car and answered by it), if no car commands are saved, and if the particular car has not entered a standby command on any of the particular floors will. In this way, the individual cars can be operated in a suitable, distributed relationship to one another to ensure good service, so that the passengers waiting at the various floor stops have essentially the same waiting times.

In a temporary state in which the traffic goes from "strong" to "weak" because of a decrease in number the passenger changes, are the command circles for a readiness position of the upper and middle, special floor excited. Therefore, the cars are appropriately distributed, with no more cars than necessary on Ground floor are provided. The cars provided in the standby position on the special floors speak quickly responding to orders from passengers waiting on the upper and middle floors. This allows the passengers without significant Waiting times are served by the cars.

According to the present invention, the distributed standby mode appropriately modified to not only have a "weak" but also a "strong" To serve traffic, and to improve operation in "heavy" traffic.
