Method for operating a lifting device and corresponding lifting device

The present invention relates to a method for operating a lifting apparatus according to the preamble of the first aspect of the patent application, the lifting apparatus having two lifting carriages arranged in the same lifting shaft and independently driven by each other; A lifting device that can be operated correspondingly according to the preamble of claim 9 of the scope of the patent application.

There are a variety of different lifting devices that include a plurality of elevator cars in a hoistway. Lifting devices (also referred to as multi-mobile lifts) having a plurality of lift cars in the same hoistway are typically each equipped with a respective drive and brake system.

Therefore, based on the respective configurations of the elevator cars, for example, a so-called zone operation in which each of the elevator cars is assigned to an area and a transfer floor for transferring passengers between the elevator cars in a plurality of different zones will be realized. It is arranged between these areas. A method for performing regional operations of such lifting devices is described in the patent application EP 1526103-A1.

There are a large number of transportation needs, especially in high-rise buildings. To meet this transportation need, a mobile body lifting device as described above can be installed.

However, current problems and capacity constraints can occur especially during peak hours. For example, in the morning, hundreds of people will enter the entrance area of the building and want to go to a higher floor, or there will be a large number of people going to work. The lowest floor to leave this building.

There are a number of different solutions for increasing transportation capacity to be able to respond to this "spike load". Thus, for example, an increase in the speed or acceleration of the elevator car or a shortening of the door opening time can be utilized. However, lifting equipment is generally not an over-designer in terms of motor output and power supply, so that an increase in cabin speed/acceleration can only be considered to a very limited extent. In addition, increasing the acceleration of the cars can have a negative impact on the person's operational feel, so the increase in transportation energy can only be achieved to a very limited extent. The shortening or optimization of the opening time has also been implemented as a standard in many lifting devices. Therefore, these measures do not bring about an obvious increase in the actual transportation energy.

Obviously, the entire lifting device in the building can also be sized so that it can handle the "spike load". However, this has the disadvantage that the lifting devices are slightly oversized during normal operation. On the one hand, such oversized lifting devices are therefore unnecessarily more expensive, and on the other hand they occupy a very large proportion of the space of one of the buildings.

The purpose of the invention is to: A method is proposed in which a multi-mobile lifting device can be used to achieve an improvement in downstream and/or upward transport energy without providing an oversized lifting device; a multi-mobile lifting device that can be operated according to this method is created device.

Implementation of this purpose As far as the method is concerned, it is disclosed in the first paragraph of the patent application scope. The feature is achieved; and as far as the lifting device is concerned, it is achieved by the features disclosed in claim 9 of the patent application.

Advantageous embodiments of the invention and several developments are defined by the respective scope of the patent application.

This new lifting device includes at least one upper lift car and a lower lift car. The two lift carriages are preferably movable vertically and upwardly in a manner substantially independent of one another in a common hoistway of the lift apparatus.

The overlap area is created by the configuration of the two lift cars. The upper lift compartment serves an area extending from the uppermost parking station of the lifting apparatus to a lower parking station disposed above the lowest parking station of the lower lifting compartment. In contrast, the lower lift car preferably serves an area extending from the upper stop station below the uppermost stop station of the upper lift car to the lowest stop station of the lift device.

The present invention is particularly distinctive due to the fact that the corresponding lifting device can operate in a normal mode and an alternate mode (e.g., a downlink replacement mode and/or an uplink replacement mode). In the normal mode, the lower lift car is primarily provided to passengers who have indicated their desire to travel to the lowest stop by the destination call. Conversely, in the down-substitution mode, the upper lift car is additionally used for passengers who want to stop at the bottom. These passengers are then transported in the upper lift car, wherein the passengers will only know during the transport that the lift car is now heading to a stop station located above the lowest stop station.

On the contrary, in the optional uplink replacement mode, the lower lift car is For those who want to travel to the top of the station. These passengers are then transported in the lower lift car, wherein the passengers will only know during the transport that the lift car is now heading to a stop station located below the uppermost stop station.

To determine if the transition from normal mode to alternate mode is to be performed, it will be checked if at least one release condition has been met.

Further details and advantages of the present invention will be described hereinafter based on an embodiment and with reference to the drawings.

Figure 1 shows, in a simplified diagram, a lifting device 10 which, as described above, is a conventional multi-mobile lifting device. The lifting device 10 includes a hoistway 11 and an upper hoisting compartment DU and a lower hoisting compartment LU are vertically movable in the hoistway.

For example, overlapping areas A and B are generated due to the arrangement of the two lift cars LU and DU. The upper lift compartment DU serves a zone B which extends from the uppermost stop station 13.n of the lifting device 10 to the lower stop station 13.2 which is placed above the lowest stop station 13.1 of the lower lift compartment LU 13.2 . On the contrary, the lower lift car LU serves an area A which extends from the upper stop station 13.n-1 below the uppermost stop station 13.n of the upper lift car DU to the lifting device 10 At the bottom stop station 13.1. If the hoistway 11 is, for example, 100 stories high, the upper lift compartment DU covers the floors 1-100, and the lower lift compartment LU covers the floors 0-99.

As long as a critical minimum distance is maintained between the two lift cars DU and LU, the lift cars DU and LU can move independently of each other in the lift In the hoistway 11.

The upper lift car DU has a first drive and brake system that includes a first hold brake (preferably a motor brake). The lower lift car LU has a second drive and brake system that includes a second hold brake (preferably a motor brake). The drive means are, for example, drive pulley drives for driving the pulleys, and the drive pulleys connect the lift cars DU, LU to the counterweight by means of the conveyor. For the sake of clarity, the drive devices and the transport devices and counterweights are not shown in FIG.

The lifting device 10 additionally preferably includes a collision protection system to prevent collision between the two elevator cars DU and LU.

Advantageously, the lifting device 10 arranges the transportation of the passengers by means of a so-called destination call control device. In this case, the elevator car is called by the input destination from the location of the building where the passenger is located (for example, in the lobby in front of the hoistway). These destination calls are thus entered by the passengers through the destination call input device. In this case, a destination call contains at least one information about the location of the destination entry and at least one information about the desired destination. The destination call input devices then transfer the destination call information to a lift control device or another lift assembly for storing and/or further processing the entered destination calls. In the case of a call car, the lift control device includes at least details about the desired travel destination (especially the floor or floor group) and details about the location (e.g., floor) of the building in which the passenger is located. In particular, this will determine which destination call input device will be activated by the passenger. This destination call control device is therefore significantly different from the conventional ones in the case of calling the car without any relevant passengers. A car call control device of any detail of the destination. In the case of the conventional control device, the input to the destination is carried out in the elevator car and is therefore after the elevator car is assigned to a destination call.

For the sake of clarity, no destination call input device is shown in Figure 1. The destination call input device can be fixedly mounted at the entrance 14.n of the lifting device 10 on the floors 13.1 to 13.n, which for example has a decimal keypad and/or a touch screen, but it can also be Mobile devices, such as mobile phones carried by passengers, cards with RF-ID devices, or the like.

The elevation control device 20, which is strongly shown in Fig. 1, receives information on the destination call input location and the destination of the trip (referred to as destination call information) by the destination call input device. This destination call information is shown in Fig. 1 by an arrow pointing to the elevation control device 20. These arrows are labeled according to the following scheme. A destination call indicating that the passenger wants to go to the lowest floor 13.1 (the lowest stop station) is represented by Z.1. Z.2 represents the destination call of the second lowest floor 13.2, Zn-1 represents the destination call of floor 13.n-1, and Zn represents the uppermost floor 13.n (the top stop station) Destination call.

As previously mentioned, in addition to this destination information, there is also input information at the elevation control device 20, and this information is used to indicate the location (e.g., floor) of the corresponding passenger at the time.

Such destination call profiles can be used to optimize the transportation energy of the lifting device 10 at any point in time, as will be described below based on different forms of embodiment.

Thus, based on this destination call profile, it can be determined how many passengers are currently making a destination call for, for example, going to the lowest stop station 13.1 of the building, and where the passengers are located in the building. According to the invention, in the normal mode, the lower lift car LU will be used to transport the passenger to the lowest stop station 13.1, since this stop station 13.1 cannot be reached by the upper lift car DU. If the elevation control device 20 confirms that the destination call Z.1 that is input to the lowest stop station is so large that the lower lift car LU is at a given time point, the transport position is in a state that may cause the passenger to wait for a long time, The lifting device 10 will then switch to the so-called lower row replacement mode. In this down-replacement mode, the upper lift car DU is used in a supplementary/assisted manner to transport passengers who wish to travel to the lowest stop station 13.1.

For this purpose, the upper lift car DU is provided at the corresponding floor and allows the passenger to board. Only after the passenger has entered the upper lift compartment DU or when this has been set in motion, the passengers are notified that the lift carriage DU only runs to a stop, for example, on the first floor above the lowest stop station 13.1. Station 13.2. After leaving the elevator car DU, the passengers can then walk through the remaining downlink route to the lowermost floor 13.1 by, for example, a (moving) staircase. In an alternative embodiment form, the passenger is informed that the lift car DU only reaches the stop stations 13.n-1 to 13.2 located in the area covered by the two lift cars DU, LU. The passengers leave the lift compartment DU on this floor and wait until the lower lift compartment LU stops so that the passengers can be taken to the lowermost floor 13.1. Therefore, the floors 13.n-1 to 13.2 which are reached by the upper lift compartment DU can be regarded as the transfer floor.

By means of this control measure, the lifting device 10 can be significantly increased Capacity, because passengers who want to reach the lowest stop station 13.1 at the same time are no longer only guided to the lower lift car LU.

According to the invention, this downstream alternative mode is used, inter alia, temporarily and in the case of special needs. In this case, according to the present invention, when one or more conditions (referred to as a start condition) are satisfied, an automatic transition from the normal mode to the downlink substitute mode can be initiated.

In the form of the first embodiment of the present invention in which the lift control device 20 relating to the amount of traffic is provided, it is determined based on the destination call Z.1-Zn whether or not those who wish to reach the passenger of the lowest stop station 13.1 The number of calls Z.1 is greater than the line transport limit LUmax of the lower lift car LU. If so, the lifting device 10 switches to the downlink replacement mode.

In this first embodiment form, the lower transport compartment LU lower line transport limit LUmax is used as the starting condition. The destination call Z.1-Z.n determined by the passenger will be detected. Then, by comparing the downstream transport limit LUmax with the currently existing destination call Z.1 to the lowest stop station 13.1, it is checked whether the number of destination calls of the passengers who want to reach the lowermost floor 13.1 is larger than this downward. Transportation limits LUmax. If so, the lift control device 20 will initiate a change from the normal mode to the downlink substitute mode.

In a second embodiment form of the invention in which the automatic lift control device 20 is provided, it will be determined based on previously determined information whether the lifting device 10 should be switched to the downlink override mode. For example, the lifting device 10 can be programmed for workdays so that the lifting device 10 can be operated from 16 pm to 16:30 pm (referred to as startup time). Under the downside replacement mode, this is because there are a large number of passengers wishing to leave the building at this point in time.

In addition to or as an alternative to this time-related design of the present invention, the downlink replacement mode can also be enabled in an emergency situation. If, for example, the building has to be evacuated, the transport energy can therefore be significantly increased.

In another form of embodiment of the invention, a so-called up-substitution mode will be used in addition to or as an alternative to the downlink replacement mode. In this case, the lifting device can be operated in the following modes: 1) normal mode or uplink replacement mode; 2) normal mode or downlink replacement mode; or 3) normal mode or downlink substitute mode and uplink substitute mode.

According to the invention, this uplink replacement mode is used, inter alia, temporarily and in situations where there are special needs. In this case, according to the present invention, when one or more conditions (referred to as start conditions) are satisfied, automatic transition from the normal mode to the uplink substitute mode can be initiated.

In the form of the third embodiment of the present invention in which the lift control device relating to the traffic amount is provided, the destination of the passenger who wants to reach the uppermost parking station 13.n will be determined based on the destination call Z.1-Zn. Whether the number of called Zn is greater than the upstream transport limit DUmax of the upper lift compartment DU. If so, the lifting device 10 will switch to the uplink override mode.

In the form of the third embodiment of the present invention, it is determined whether the number of destination call Zns existing is greater than the upstream transportation limit by comparing the upstream transportation limit DUmax with the destination call Zn currently presenting the uppermost floor 13.n. DUmax so that it can then be changed to the uplink substitute mode.

In a form of the fourth embodiment of the invention in which the automatic lift control device 20 is provided, it will be determined based on previously determined information whether the lifting device 10 should be switched to the uplink override mode. For example, the lifting device 10 can be programmed for the working day so that the lifting device is always operated in the uplink replacement mode between 7 am and 8 am, because there will be a large amount at this point in time. Passengers enter the building.

In accordance with the present invention, the lift control device 20 and/or the destination call device will coordinate or collectively coordinate all of the lift LUs, DUs. For this purpose, the destination call control device can be connected to the elevation control device 20 by known and proven means. Control of the drive unit occurs on the lift control unit 20 by a corresponding signal or other control amount, as indicated by arrows A1 and B1 in FIG.

The present invention is distinguished by the fact that there is no change at the overlapping areas of the individual lift cars LU, DU. Conversely, the setting of each of the elevator cars LU and DU will increase the downstream and/or uplink transportation energy, which is caused by the use of a less suitable elevator car to transport passengers, although the elevator car does not arrive completely. The destination of hope.

The method according to the invention is obviously optimally operated when the two lift cars LU, DU are identical, so that the passengers do not know that the trip will not take them completely when entering the lift cars LU, DU. The destination entered by the destination call control device.

Depending on various embodiments of the present invention, the lifting device 10 may return to the normal mode after satisfying the so-called reset condition. In the form of an embodiment relating to traffic volume, additional limiting values may be used, such as LUmin and/or DUmin to switch to normal mode when falling below these limit values.

In an embodiment form that operates in a time dependent manner, another time may be presented as a reset condition.

The embodiment of the invention shown in Fig. 1 includes a destination call device (not shown) that is connected to the lift control device 20 in an operational state, wherein the connection is designed such that the lift control device 20 can be The destination call Z.1-Zn is received from this destination call device and the status of these calls for evaluation is provided.

It is schematically shown in Fig. 1 that the lift control device 20 can include a software and/or hardware module 21 that contains a number of necessary components for performing the comparison operation. However, the software and/or hardware module 21 can also be configured at any desired location. The software and/or hardware module 21 can also include a temporary memory that temporarily stores the incoming destination calls Z.1-Z.n. This memory is then eliminated each time the passenger has been shipped. A so-called (shift) register is particularly suitable in which destination calls are arranged and processed in series.

The principle of this (shift) register is illustrated in Figures 2A and 2B based on two typical cases. A situation is shown in Figure 2A in which the number of destination calls Z.1 (shown as black horizontal stripes) to the lowest stop station 13.1 is less than the downstream transport limit LUmax. The corresponding destination call Z.1 is queued in the scratchpad 22. Since the instant shown in Fig. 2A does not exceed the downstream transport limit LUmax, it does not change to the downlink replacement mode, and the register 23 of the upper lift compartment DU remains empty.

In Fig. 2B, a situation is shown in which the number of destination calls Z.1 of the trips in the register 22 to the lowest stop station 13.1 is greater than the downstream transport limit LUmax. Since this downstream transport limit LUmax has been exceeded, the change to the downlink override mode will be changed, and the register 23 of the upper lift compartment DU will take over a portion of the destination call Z.1 from the register 22, as indicated by arrow 24.

If the lifting device 10 is configured in the down or upside replacement mode according to the invention, the passenger will only know that the elevator car at the moment does not reach the desired floor after the boarding of the car or during the transportation, but will only arrive A stop at a distance close to this floor. The elevator cars DU, LU may be equipped with suitable means for correlating the passengers in an audio and/or video manner.

Thus, for example, in the case of the downlink replacement mode, the passenger may be stated as follows before reaching the parking station 13.2: if the user wants to reach the lowermost floor 13.1, he or she must leave the compartment DU at the first floor and use the descending stairs. Or an escalator. More audio and/or video devices may be installed in the area in front of the corresponding hoistway 11 so that the passenger exiting at the first floor 13.2 can indicate the path to the lowermost floor 13.1. For example, a signal can be sent to a stationary escalator so that the escalator begins to run shortly before the passenger begins to take the alternative trip.

In an alternative embodiment form, the passengers are stated shortly before the stop stations 13.n-1 to 13.2 in the common travel area of the upper and lower lift cars DU, LU, as follows: if the user wants to reach the lowermost floor 13.1 , etc., must leave the compartment DU at the floors 13.n-1 to 13.2 that will arrive and transfer to Lower lift compartment LU. More audio and/or video devices can be installed in the area in front of the corresponding hoistway 11 to facilitate notification of passengers getting off at transfer floors 13.n-1 to 13.2. When the lower lift car LU is ready to go to the bottom Floor 13.1.

From the uppermost floor 13.n-1, the way to use the stairs or escalators from the service of the lower lift car LU to the floor 13.n above it can be similarly applied to the uplink alternative travel. In addition, the previous description regarding the transfer from the lower lift car LU to the upper lift car DU on the transfer floors 13.2 to 13.n-1 of the common travel areas of the two lift cars LU, DU is similarly applicable to the case of the uplink substitute travel. under. Finally, the audio and/or video device can similarly be used for this downstream alternative trip.

After understanding the present invention, an expert can operate one or more lifting devices in accordance with the present invention within a building.
