The subject matter disclosed herein relates generally to the field of elevator systems, and specifically to a method and apparatus for coordinating the operation of multiple elevator systems split into groups.
Commonly, elevator cars are organized into elevator groups serving a range of landings of a building rather than each elevator car serving every floor of a building. Once established, the ranges of landings typically remain unchanged due to physical constraints in the elevator system. In conventional elevator systems, a building may have several groups where the floors served by one group do not overlap with the floors served by any other group except, perhaps, the main lobby or other special floors.
According to an embodiment, a method of operating a building elevator system within a building having a plurality of landings is provided. The method including: controlling a first elevator group including one or more elevator systems, wherein each of the one or more elevator systems of the first elevator group includes an elevator car configured to serve a first range of landings; controlling a second elevator group including one or more elevator systems, wherein each of the one or more elevator systems of the second elevator group include an elevator car configured to serve a second range of landings; detecting at least one of a predicted passenger response time, a time of day, an amount of traffic received by the first elevator group, an amount of traffic received by the second elevator group, an amount of traffic within the first range of landings, an amount of traffic within the second range of landings, the amount of traffic received by the first elevator group relative to the amount of traffic received by the second elevator group, and the amount of traffic within the first range of landings relative to the amount of traffic within the second range of landings; and adjusting a range of landings served by one or more elevator systems of the second elevator group in response to at least one of the predicted passenger response time, the time of day, the amount of traffic received by the first elevator group, the amount of traffic received by the second elevator group, the amount of traffic within the first range of landings, the amount of traffic within the second range of landings, the amount of traffic received by the first elevator group relative to the amount of traffic received by the second elevator group, and the amount of traffic within the first range of landings relative to an amount of traffic within the second range of landings.

It should be understood, however, that the following description and drawings are intended to be illustrative and explanatory in nature and non-limiting.
The present disclosure is illustrated by way of example and not limited in the accompanying figures in which like reference numerals indicate similar elements.
The tension member 107 engages the machine 111, which is part of an overhead structure of the elevator system 101. The machine 111 is configured to control movement between the elevator car 103 and the counterweight 105. The position reference system 113 may be mounted on a fixed part at the top of the elevator shaft 117, such as on a support or guide rail, and may be configured to provide position signals related to a position of the elevator car 103 within the elevator shaft 117. In other embodiments, the position reference system 113 may be directly mounted to a moving component of the machine 111, or may be located in other positions and/or configurations as known in the art. The position reference system 113 can be any device or mechanism for monitoring a position of an elevator car and/or counter weight, as known in the art. For example, without limitation, the position reference system 113 can be an encoder, sensor, or other system and can include velocity sensing, absolute position sensing, etc., as will be appreciated by those of skill in the art.
The controller 115 is located, as shown, in a controller room 121 of the elevator shaft 117 and is configured to control the operation of the elevator system 101, and particularly the elevator car 103. For example, the controller 115 may provide drive signals to the machine 111 to control the acceleration, deceleration, leveling, stopping, etc. of the elevator car 103. The controller 115 may also be configured to receive position signals from the position reference system 113 or any other desired position reference device. When moving up or down within the elevator shaft 117 along guide rail 109, the elevator car 103 may stop at one or more landings 125 as controlled by the controller 115. Although shown in a controller room 121, those of skill in the art will appreciate that the controller 115 can be located and/or configured in other locations or positions within the elevator system 101. In one embodiment, the controller may be located remotely or in the cloud.
The machine 111 may include a motor or similar driving mechanism. In accordance with embodiments of the disclosure, the machine 111 is configured to include an electrically driven motor. The power supply for the motor may be any power source, including a power grid, which, in combination with other components, is supplied to the motor. The machine 111 may include a traction sheave that imparts force to tension member 107 to move the elevator car 103 within elevator shaft 117.
Although shown and described with a roping system including tension member 107, elevator systems that employ other methods and mechanisms of moving an elevator car within an elevator shaft may employ embodiments of the present disclosure. For example, embodiments may be employed in ropeless elevator systems using a linear motor to impart motion to an elevator car. Embodiments may also be employed in ropeless elevator systems using a hydraulic lift to impart motion to an elevator car.

Each landing 125a-125z in the building 102 of
The redirector 110 may be in communication with the controller 115a-115j of each elevator system 101a-101j through a dispatcher 210a-210b and a server 212a-212b, as shown in
The servers 212a-212b are similar to a redirector 110 being that the servers 212a-212b manages the destination entry devices 89a-89z related to a particular group 112a-112b (e.g., the redirector 110 interfaces with destination entry devices 89a-89z that are shared between groups 112a-112b). In an embodiment, the servers 212a-212b may be configured to operate as a pass through between the redirector 110 and the dispatcher 210a-210b associated with the server 212a-212b.
The controllers 115a-115j can be combined, local, remote, cloud, etc. The redirector 110 is configured to control and coordinate operation of multiple elevator systems 101a-101j. The redirector 110 may be an electronic controller including a processor and an associated memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform various operations. The processor may be, but is not limited to, a single-processor or multi-processor system of any of a wide array of possible architectures, including field programmable gate array (FPGA), central processing unit (CPU), application specific integrated circuits (ASIC), digital signal processor (DSP) or graphics processing unit (GPU) hardware arranged homogenously or heterogeneously. The memory may be but is not limited to a random access memory (RAM), read only memory (ROM), or other electronic, optical, magnetic or any other computer readable medium.
The redirector 110 is in communication with each of the elevator destination entry devices 89a-89z of the building elevator system 100, which are shared by more than one group 112a-112b. The first range of landings 250a or the second range of landings 250b may be adjusted in response to at least one of a time of day and an intensity of traffic within each of the first range of landings 250a and the second first range of landings 250b. If the redirector 110 is monitoring the elevator calls 310 coming in from the elevator destination entry devices 89a-89z and determines that the one of the elevator groups 112a-112b needs additional assistances answering the calls then the redirector 110 may adjust the range of landings served by one or more elevator systems 101. The redirector may be remote, local, cloud, or any combinations thereof.
As shown in the example of
As shown in the example of
The redirector 110 may also be configured to adjust the range of landings served by one or more elevator systems 101 in accordance with a preset schedule by the time of day (i.e., known traffic patterns due to history) or in accordance with the prevailing traffic pattern.

At block 404, a first elevator group 112a comprising one or more elevator system 101a-101e is controlled. Each of the one or more elevator systems 101a-101e of the first elevator group 112a comprises an elevator car 103a-103e configured to serve a first range of landings 250a.
At block 406, a second elevator group 112b comprising one or more elevator system 101f-101j is controlled. Each of the one or more elevator systems 101f-101j of the second elevator group 112b comprises an elevator car 103f-103j configured to serve a second range of landings 250b. In an embodiment, the first range of landings 250a does not include landings within the second range of landings 250b with the exception of an egress landing 125a.
In another embodiment, first range of landings 250a is a lower range of landings and the second range of landings 250b is a higher range of landings located at a higher elevation than the lower range of landings with the exception of an egress landing 125a.
At block 408, at least one of a predicted passenger response time, a time of day, an amount of traffic received by the first elevator group 112a, an amount of traffic received by the second elevator group 112b, an amount of traffic within the first range of landings 250a, an amount of traffic within the second range of landings 250b, the amount of traffic received by the first elevator group 112a relative to the amount of traffic received by the second elevator group 112b, and the amount of traffic within the first range of landings 250a relative to the amount of traffic within the second range of landings 250b is detected.
The predicted passenger response time (e.g., waiting time or time to destination) could be based on the conditions of each elevator system 101 within an elevator group 250a-250b at the time of the call. The predicted passenger response time to a new call for given elevator system 101 may be calculated so that it is understand the likely waiting time (or time to destination) if an elevator call were to be assigned to the elevator system 101. The general application of a predicted passenger response time calculation is by running that calculation through each of the eligible elevator systems 101a-101j at the time when an elevator call 310 is received. Note that a less computationally-intensive predicted passenger response time could be based purely on the time of day by learning the response times from historical data.
For example, the decision on whether or not to consider an elevator car 103f-103h to receive a call involving landing 125l-125m might be based on predicting the response time to serve a given elevator call 310. If one of elevator systems 101a-101e can best serve the elevator call 310, then the elevator call 310 should be assigned to one of those elevator systems 101a-101e; whereas, if one of the elevator systems 101f-101h can best serve the elevator call 310, the elevator call 310 should be assigned accordingly. There may be variations, such as if the predicted passenger response time by service from elevator systems 101a-101e is within an acceptable threshold, then assign to one of those elevator systems 101a-101e but otherwise, consider the predicted passenger response time of elevator systems 101f-101h as well when block 270 is enabled.
The amount of traffic may be based on the volume of elevator car 103 traffic within a timeframe. For example, the amount of traffic could be the total volume of traffic within the timeframe, the volume of traffic from an origin landing within the time frame, the volume of traffic to a destination floor within the timeframe, the volume of traffic between a subset of landings to another subset of landings within the timeframe. The amount of traffic may also be not just a volume, but also a relative proportion of elevator car 103 traffic. In the example of
At block 410, a range of landings 125 (e.g., see block 270 in
The method 500 may further comprise: receiving an elevator call for a landing 125m-125l within the first range of landings 250a; determining an elevator car 103a-103e of the one or more elevator systems 101a-101e of the first elevator group 112a or an elevator car 103f-103h of the one or more elevator systems 101f-101h of the second elevator group 112b to best serve the elevator call 310 in response to a relative amount of traffic with the first range of landings 250a and the second range of landings 210; and moving the elevator car determined to the landing 125m-125l within the first range of landings 250a.
In an embodiment, the range of landings served by one or more elevator systems 101 of the second elevator group 112b may be adjusted to serve one or more landings gravitationally above the second range of landings 250b and/or gravitationally below the second range of landings 250b. In another embodiment, the range of landings served by one or more elevator systems 101 of the second elevator group 112b may be adjusted to serve one or more landings of the first range of landings 250a.
