Definitions

  • the subject matter disclosed herein generally relates to elevator systems and, more particularly, to emergency operation of elevator systems.
  • Elevator systems are designed to convey passengers between floors or landings within a building. During emergencies, it is important to transport passengers to an evacuation landing to enable safe exit from the building. For example, during a fire emergency at a floor within a building, passengers within an elevator should be conveyed to an evacuation landing that is away from the landing having the fire. Typically, elevator systems will perform a current movement, e.g., travel to a preselected or entered destination landing, and then travel to the evacuation landing, to enable the passengers to exit an elevator car at the evacuation landing. Improved systems for delivering passengers to evacuation landings may be advantageous.
  • control methods for elevator systems include receiving emergency information at an elevator controller, activating an emergency mode of operation of the elevator system, determining a position and direction of travel of an elevator car within an elevator shaft with an absolute positioning system, wherein the determination is made in real-time, and controlling operation of the elevator car to travel to an evacuation landing when the emergency mode of operation is activated.
  • further embodiments of the methods may include that the emergency information includes information identifying a landing having an emergency.
  • further embodiments of the methods may include that the elevator controller determines a direction of travel of the elevator car based on information obtained from the absolute positioning system.
  • the methods further include, when the elevator car is determined to be traveling in a direction away from the evacuation landing, the elevator controller changes direction of travel of the elevator car to a direction toward the evacuation landing.
  • further embodiments of the methods may include that the absolute positioning system includes a position encoder in communication with the elevator controller.
  • further embodiments of the methods may include that the elevator car is at a first position when the emergency mode of operation is activated, wherein when the elevator is traveling to a destination floor in a direction away from the evacuation landing, the controller changes a direction of travel of the elevator car at a second position wherein the second position is a location closer to the evacuation landing than the destination floor.
  • controlling operation of the elevator car comprises slowing movement of the elevator car within the elevator shaft, stopping the elevator car, and directing the elevator car to the evacuation landing.
  • elevator systems include an elevator car within an elevator shaft and moveable between a plurality of landings, an absolute positioning system arranged to detect an absolute position and direction of travel of the elevator car within the elevator shaft, wherein the detection is made in real-time, and an elevator controller in operable communication with an emergency system.
  • the elevator controller is configured to receive emergency information from the emergency system, activate an emergency mode of operation, receive position information of the elevator car within the elevator shaft from the absolute positioning system, wherein the information is received in real-time, and control operation of the elevator car to travel to an evacuation landing when the emergency mode of operation is activated.
  • further embodiments of the elevator systems may include that the emergency information includes information identifying a landing having an emergency.
  • further embodiments of the elevator systems may include that the elevator controller determines a direction of travel of the elevator car based on information obtained from the absolute positioning system, the elevator controller further configured to change a direction of travel of the elevator car to a direction toward the evacuation landing when the elevator car is determined to be traveling in a direction away from the evacuation landing.

  • further embodiments of the elevator systems may include that controlling operation of the elevator car comprises slowing movement of the elevator car within the elevator shaft, stopping the elevator car, and directing the elevator car to the evacuation landing.
  • FIG. 1 is a perspective view of an elevator system 101 including an elevator car 103, a counterweight 105, a roping 107, a guide rail 109, a machine 111, a position encoder 113, and a controller 115.
  • the elevator car 103 and counterweight 105 are connected to each other by the roping 107.
  • the roping 107 may include or be configured as, for example, ropes, steel cables, and/or coated-steel belts.
  • the counterweight 105 is configured to balance a load of the elevator car 103 and is configured to facilitate movement of the elevator car 103 concurrently and in an opposite direction with respect to the counterweight 105 within an elevator shaft 117 and along the guide rail 109.
  • the roping 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 encoder 113 may be mounted on an upper sheave of a speed-governor system 119 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 encoder 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 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.
  • 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 encoder 113.
  • the elevator car 103 may stop at one or more landings 125 as controlled by the controller 115.
  • the controller 115 can be located and/or configured in other locations or positions within the elevator system 101.
  • the machine 111 may include a motor or similar driving mechanism.
  • 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 buffers 129 may be secured in the pit 127 of the elevator shaft 117, and may be secured to the guide rail 109, e.g., on a vertical portion or a horizontal portion of the guide rail 109, as shown in FIG. 1 .
  • the buffers 129 may be hydraulic or foam type buffers, as known in the art, or may take other configurations.
  • the buffers 129 are configured to impact a bottom surface of the elevator car 103 in the event the elevator car 103 falls within the elevator shaft 117.
  • the buffers 129 may be configured or fastened directly on or to a floor of the pit 127.
  • the buffers may be affixed to the bottom of the elevator car 103 instead of or in addition to the pit buffers 129 shown in FIG. 1 .
  • FIG. 1 is merely a non-limiting example presented for illustrative and explanatory purposes.
  • the elevator system 101 is designed to convey passengers between the landings 125 within a building. During emergencies, it is important to transport passengers to an evacuation landing to enable safe exit from the building.
  • the evacuation landing will be a landing different from a landing where the emergency is occurring. For example, during a fire emergency at a floor within a building, passengers within the elevator car 103 should be conveyed to an evacuation landing that is away from the landing having the fire.
  • elevator systems will complete a current travel pattern, e.g., travel to a preselected or entered destination landing by one of the passengers within the elevator car 103, and then travel to the evacuation landing.
  • an emergency mode of operation of the elevator system 101 activates. If the elevator car 103 is traveling in a direction opposite to the level set for evacuation, the elevator car 103 will continue to run until the next landing and then move to the landing configured for evacuation.
  • These systems rely upon identifying the position of the elevator car 103 based on a given landing, and thus additional travel time may be required before the direction of travel of the elevator car 103 is reversed to perform an evacuation operation.
  • FIG. 2 a schematic illustration of an elevator system 201 having a typical emergency operation procedure is shown.
  • the elevator system 201 includes an elevator car 203 that is arranged to travel within an elevator shaft 217 between a number of landings located along the elevator shaft 217.
  • the elevator system 201 includes a first landing 225a, a second landing 225b, and a third landing 225c.
  • FIG. 2 is merely schematic and more landings may be provided along the elevator shaft, and a landing interval 231 may include additional landings not shown.
  • a landing interval, as used herein, is a vertical span or distance within an elevator shaft between any two given landings.
  • a landing interval may be a distance between two sequential landings, e.g., a distance between Floor 1 and Floor 2.
  • the landing interval may be significantly greater, for example, in systems for high-rise buildings that have a ground floor lobby (e.g., Floor 1) and then the first stop for a specific elevator shaft may be Floor 20 (with the specific elevator car providing travel to Floors 20-29, and a different elevator or elevators providing service to floors 2-19).
  • the landing interval may include additional intermediate landings, such as a distance between Floor 1 and Floor 5, with Floors 2-4 (and landings/landing doors) being present but encompassed in the Floor 1 to Floor 5 landing interval.
  • the landing interval is merely a distance between landings within an elevator shaft, and is not to be limited by a specific arrangement of floors and/or landings of a given elevator system.
  • the movement or travel of the elevator car 203 is controlled by a controller 215, as will be appreciated by those of skill in the art.
  • the controller 215 can be arranged to receive destination inputs from users of the elevator system 201, with inputs being received from the landings and/or within the elevator car 203, for example, as appreciated by those of skill in the art.
  • the controller 215 may further be operably connected to and/or in communication with an emergency system of a building in which the elevator system 201 is located, and thus emergency signals or identification information can be received by the controller 215 to enable specific control modes of the elevator system 201.
  • the elevator car 203 is traveling from the first landing 225a to the second landing 225b, and thus, in the illustration, the elevator car 203 is shown at a first position 203'.
  • Such direction of travel may be initiated by a passenger request by a passenger within the elevator car 203.
  • an emergency 233 such as a fire, is located at the second landing 225b.
  • the emergency 233 may be at the second landing 225b or on the floor of the second landing 225b.
  • the emergency 233 can be identified by a fire alarm, automatically or manually activated, which identifies the landing at which the emergency 233 is occurring.
  • the fire alarm or other emergency system of the building can provide information to the controller 215 to prompt an emergency mode of operation of the elevator system 201.
  • the elevator system 201 When an emergency is identified, the elevator system 201 will enter an emergency mode of operation that is operated by the controller 215. In such mode, the elevator car 203 will be controlled to travel to the third landing 225c (evacuation landing). In operation, the position and direction of the travel of the elevator car 203 is determined and specific action is taken based on such information.
  • the elevator car 203 will not travel to any new destinations, and the elevator car doors will open to allow passages to evacuate. If the elevator car 203 is traveling in a direction of the third landing 225c, whether the third landing 225c is the actual destination or not, the elevator car 203 will travel to and stop at the third landing 225c to allow passengers to evacuate. If in such situation a different landing was selected by a passenger, the selected floor will be bypassed or not stopped at, and the elevator car 203 will only travel to the evacuation floor (third landing 225c). Finally, if the elevator car 203 is traveling in a direction away from the third landing 225c at the time of activation of the emergency mode of operation as shown in FIG.
  • the elevator car 203 will change direction of motion, without stopping at a landing and opening of the elevator doors. For example, at a second position 203", which is at the current destination landing 225b, the elevator car 203 will stop, the doors will not open, and then immediately be diverted to the evacuation landing (e.g., the third landing 225c), indicated as a third position 203"'.
  • the controller 215 will prevent elevator doors from opening at the second landing 225b because of the emergency 233, and will convey any passengers within the elevator car 203 to the third landing 225c (i.e., the evacuation landing).
  • the elevator car 203 If the elevator car 203 is traveling from the first landing 225a to the second landing 225b and the emergency operation is activated, and there are additional landings between the first landing 225a and the second landing 225b, the elevator car 203 will stop at the next landing in the direction of travel, stop, the doors will not open, and then change direction to move to the third landing 225c, with the destination landing never reached.
  • the control system may be improved upon by quickly adjusting a direction of travel of the elevator car when an emergency is identified.
  • embodiments described herein are directed to elevator control systems that can provide increased security and safety to passengers within an elevator car during an emergency because an evacuation may be more quickly achieved.
  • the elevator car during an emergency mode of operation, may not be required to continue to travel to the next landing in a direction of travel, but rather may change direction immediately, even if the elevator car is located between landings or traveling within a large landing interval (e.g., within landing interval 231 shown in FIG. 2 ).
  • the elevator system 301 includes an elevator car 303 that is arranged to travel within an elevator shaft 317 between a plurality of landings.
  • the elevator system 301 includes a first landing 325a, a second landing 325b, and a third landing 325c.
  • FIG. 3 is merely schematic and more landings may be provided along the elevator shaft, and a landing interval 331 may include additional landings not shown.
  • the movement or travel of the elevator car 303 is controlled by a controller 315, as will be appreciated by those of skill in the art.
  • the controller 315 can be arranged to receive destination inputs from users of the elevator system 301, with inputs being received from the landings and/or within the elevator car 303, for example, as appreciated by those of skill in the art.
  • the controller 315 may further be operably connected to and/or in communication with an emergency system of a building in which the elevator system 301 is located, and thus emergency signals or identification information can be received by the controller 315 to enable specific control modes of the elevator system 301.
  • the elevator car 303 is traveling from the first landing 325a to the second landing 325b, and thus, in the illustration, the elevator car 303 is shown at a first position 303'.
  • Such direction of travel may be initiated by a passenger request by a passenger within the elevator car 303.
  • an emergency 333 such as a fire, is located at the second landing 325b.
  • the emergency 333 may be at the second landing 325b or on the floor of the second landing 325b.
  • the emergency 333 can be identified by a fire alarm, automatically or manually activated, which identifies the landing at which the emergency 333 is occurring.
  • the fire alarm or other emergency system of the building can provide information to the controller 315 to prompt an emergency mode of operation of the elevator system 301.
  • the elevator system 301 When an emergency is identified, the elevator system 301 will enter an emergency mode of operation that is operated by the controller 315. In such mode, the elevator car 303 immediately, or substantially immediately, changes position from a direction toward the emergency 333 and/or away from an evacuation landing to a direction toward the evacuation landing. For example, as shown, a second position 303" of the elevator car 303 is shown substantially overlapping with the first position 303' of the elevator car 303, thus indicating an immediate diversion to an evacuation landing (e.g., the third landing 325c), indicated as a third position 303"'. As used herein, the term “immediately" is used in the context of elevator operation, and consideration made with respect to the safety of passengers within an elevator car.
  • the change in direction occurs with the speed of operation of components of the elevator system.
  • brakes of the elevator car will be engaged to slow the travel of the elevator car to bring the elevator car to a complete stop.
  • the stopped position may be a position between landings of an elevator shaft, and does not have to be a landing position as used by prior systems.
  • the elevator car will change direction of travel to convey passengers to an evacuation landing (e.g., the third landing 325c).
  • embodiments provided herein enable a prompt transition to move the elevator car to the evacuation landing. For example, if the elevator car is at a position between Floors 5 and 6 of an elevator shaft, with a current destination being Floor 7, and an emergency occurs at Floor 3 and the evacuation landing is Floor 1, the elevator car will slow to a stop before reaching Floor 6 (or proximate Floor 6) without reaching Floor 7. At this time, once stopped, the elevator car will be conveyed downward to the evacuation landing, passing by Floor 3 without stopping.
  • the immediate control and change in direction of travel of the elevator car 303 can be achieved through integration or inclusion of absolute positioning systems that are part of the elevator system 301. That is, using an absolute position system, such as an encoder system located on the elevator car 303, the controller 315 can immediately identify the position of the elevator car 303 within the elevator shaft 317 and appropriately control the travel of the elevator car 303 to the third landing 325c in a timely manner, thus saving time and providing additional safety to passengers within the elevator car 303.
  • the absolute positioning system may be any absolute positioning system as known in the art, including encoders, optical systems, mechanical systems, etc. that provide real-time position data associated with the position of the elevator car 303 within the elevator shaft 317 to the controller 315.
  • the elevator car 303 is located at the first position 303' when the emergency mode of operation is activated. Because the elevator car 303 is traveling toward a destination floor in the direction of the emergency 333 (or to the second landing 325b having the emergency) the elevator car will travel to the second position 303" which is toward the destination floor, with the second position 303" being a location closer to the evacuation landing (e.g., third landing 325c) than the destination floor (e.g., second landing 325b). That is, the elevator car 303 will not travel to the destination floor prior to being directed to the evacuation floor. Further, it is noted that in this illustrative embodiment, the elevator car 303 is traveling in a direction away from the evacuation landing and the control process is arranged to redirect the travel of the elevator car in a direction toward the evacuation landing.
