Definitions
- the present invention relates to a multiple level building and, more particularly, to an elevator system utilizing an emergency elevator evacuation control system that allows the use of the elevators as a means of reliable egress and evacuation during an emergency.
- high-rise buildings In multiple level buildings it is difficult to evacuate building occupants via the stairs.
- mid-rise buildings There are two classifications of buildings relative to fire and life safety: high-rise buildings and mid-rise buildings. The major distinction is that a standard hook and ladder type fire apparatus can only reach the point of a building about 75 feet or 6 floors above the ground, so "high-rise” buildings, those above about 6 floors, must be evacuated from within the building.
- the building's occupants are forced to either use an exit stairway to evacuate or remain in the burning building until rescued by the fire department.
- the stairway doors are typically propped open with fire hoses, thereby allowing smoke from the fire floor to enter the stairway. Accordingly, that stairway is not suitable for evacuation of the building occupants during an emergency.
- the evacuation of people is the primary responsibility of the fire department.
- the fire department personnel do not begin a fire attack until the building occupants are safe.
- Conventional evacuation of building occupants is a very time consuming process. During a fire, the chaotic environment increases the complexity and danger of an evacuation procedure, which also usually increases the time required to evacuate the building. It is even more difficult and time consuming to evacuate the non-ambulatory, injured, and disabled occupants.
- an alarm signal is manually or automatically provided to the fire department.
- the fire department Upon receiving the alarm signal, the fire department only knows that an alarm has been activated, but it does not know the status of the building systems until the response team arrives at the building and access the building's fire alarm panel or other data information bank. As a result, the response team loses valuable time with respect to controlling the building conditions and establishing a desired building evacuation sequence and emergency response strategy for the particular building.
- an incident command post is established in the main floor lobby upon arrival by the fire department.
- the fire department personnel can then override the elevator system and use the elevators to send an investigation team to a safe point several floors below the fire floor.
- the investigation team then takes the stairs to the fire floor to assess the extent of the fire involvement and determine the necessary evacuation procedures.
- Fire Department personnel and equipment are then typically staged two floors below the fire floor and a rescue assistance area is established four floors below the fire floor. Building occupants are then initially evacuated through the stairway to the rescue assistance area.
- a multiple floor building contains a vertical elevator shaft defined by a top, bottom and vertical structural walls through which an elevator car travels between floors.
- An opening in one of the structural walls at each floor forms a hoistway entrance through which building occupants can safely pass into and out of the elevator car when the elevator car is adjacent to the hoistway entrance during non-emergency conditions.
- An interlock mechanism connects the elevator car door to the hoistway door when the elevator car is adjacent to the hoistway entrance and the elevator car door opened or closed.
- the elevator car's vertical travel in the hoistway is controlled by a conventional elevator control system.
- the elevator control system typically includes a motion controller and a car controller that receives signals from hall call stations located on each floor.
- the elevator control system is adapted to position the car adjacent the signaling floor to allow passengers to enter or exit the car.
- a "send" or "floor destination” button within the car is activated, a signal is sent to the elevator control system, which in turn moves the car to the designated floor and opens the door to allow passengers to exit the car.
- the elevator control system permits the building occupants to quickly and efficiently travel between floors of the multi level building during normal conditions.
- the typical high-rise building has a fire alarm/smoke detection system, such as a system manufactured by the Simplex Corporation.
- the fire alarm/smoke detection system is comprised of a plurality of smoke and heat sensing devices which are remotely located throughout the building and capable of detecting the early signs of a building fire. These remote detectors are electrically connected to a central fire alarm panel and are functional to either open or close a series of relay contacts, thereby capable of sending a signal to a building security station, to the fire department, and to an alarm system that alerts the building occupants with audible and strobe alarms.
- the central fire alarm panel also initiates the operation of fire doors, air conditioning systems, and the like within the building.
- the fire alarm/smoke detection system also has an auxiliary relay contact as a backup system that is functionally connected to the elevator control system.
- the elevator control system is programmed, such that when it receives a distinctive signal from the central fire alarm panel, the elevator control system recalls all elevator cars to a predesignated floor, e.g., the lobby floor, and prevents elevator cars from stopping at a floor where smoke has been detected.
- a smoke detection system that is designed and installed in accordance with industry standards. At least one smoke detector is located in each elevator lobby and is functionally connected to the elevator control system. Additional remote smoke detectors may be located throughout the building and are functionally connected to the elevator control system.
- an alarm signal activates building emergency systems, which results in the closing of certain predetermined doors, sounding audible alarms, and the like.
- the elevator recall function is activated either automatically or manually, and the elevator control system deactivates the hall call stations and the car destination buttons.
- the elevator control system de-energizes the motion controller, stops the car's ascent, and activates the motion controller to position the car at a predesignated egress floor. If the car is moving downwardly, the elevator control system activates the motion controller to continue the decent to the predesignated egress floor.
- An elevator car to be used as an emergency means of egress, which are not all provided by conventional elevator systems: reliable power, a smoke free hoistway shaft, no unshielded electronics in the hoistway or machine room that can be damaged by water, and the ability of the elevator system to respond to changing building conditions due to migrating smoke. Power outages can stall the elevator car, trapping passengers within the hoistway shaft and further consuming fire department resources to locate the stalled car and evacuate the trapped passengers.
- An emergency power source is only a mandatory building code requirement in buildings above 75 feet to the highest occupied level. Accordingly, there is a need for an elevator system that is usable for emergency evacuation of building occupants during a building fire or other emergency.
- At least one model building code in the United States prescribes an enclosed elevator lobby in all buildings to separate the hoistway shaft from the remainder of the building in an effort to control smoke.
- Some building code jurisdictions allow an air pressurization system utilizing the elevator hoistway shaft to create positive air flow from the shaft into the fire floor to blow smoke out of and away from the hoistway shaft.
- An automatically deployable hoistway door gasketing system is described in U.S. Patent Nos. 5,195,594 and 5,383,510 to keep smoke from entering the hoistway. Additional methods of providing a smoke barrier at the hoistway door are described in my co- pending U.S. applications, namely, U.S. Patent Application No. 08/732,129, filed October 18, 1996, and U.S. Patent Application No. 08/423,958, filed April 18, 1995, each of which is incorporated herein by reference in their entireties.
- Water used for fire suppression such as from automatic fire sprinklers or from the fire department hoses, is usually present during a building fire. Water can enter the hoistway and short circuit the car controls located on the top of the elevator car. A raised sill at the hoistway door or a slight slope of the lobby floor away from the hoistway door can help prevent water from draining into the hoistway shaft. Water entering the hoistway shaft can also be controlled by the water shield/drainage system for the hoistway door, described in my co-pending U.S. Patent Application No. 08/751,306, filed November 18, 1996, which is incorporated herein by reference in its entirety.
- the evacuation time as calculated in the "Routine Analysis of the People Movement Time for Elevator Evacuation" is about forty minutes for an eleven story building using a single elevator. A twenty-one story building was estimated to take three hours to evacuate. Interviews of building occupants after actual fire incidents indicate the initiation time from first hearing an alarm to beginning any evacuation sequence may exceed thirty minutes. Therefore, the use of the conventional elevator systems for evacuation is neither efficient nor realistic in its present configuration.
- the present invention is directed toward a transportation system with an emergency evacuation control system that overcomes problems experienced in the prior art and provides additional benefits.
- One embodiment of the invention provides a multistory building having a plurality of floors, a plurality of detectors, such as smoke detectors, and a vertical transportation system that is usable for moving building occupants between selected floors during an emergency condition in the building.
- the building includes an air handling system, an emergency suppression system, and a signal control system.
- the signal control system is coupled to the detectors to receive a detection signal, and is coupled to the vertical transports system, the air handling system, or the emergency suppression, each of which provides a status signal to the signal control system.
- the signal control system has a communication mechanism connectable to a remote communication system at a location remote from the building, such as a fire department.
- the communication mechanism sends the detection signal and at least one of the status signals to the remote communication system to provide building status information to the location remote from the building.
- the vertical transportation system includes a transport unit that is positionable in the building at locations adjacent to selected floors.
- a transport controller is coupled to the transport unit to move the transport unit to the locations adjacent to the selected floors.
- a control unit is coupled to the transport controller to send a selected control signal to the transport controller to move the transport unit to one of the floors.
- the control unit is coupled to the detectors to receive a detector signal from a signaling detector that has detected an emergency condition in the building.
- the control unit is programmed to identify the floor where the signaling detector is located and defines that floor as a signaling floor.
- the control unit is also programmed to define an evacuation zone in a portion of the building relative to the signaling floor.
- the evacuation zone includes the signaling floor, a priority evacuation floor located one floor away from the signaling floor, and an evacuation assistance floor that is spaced apart from the signaling floor and the priority evacuation floor.
- the control unit is also programmed to send the control signal to the transport controller to move the transport unit within the evacuation zone and to evacuate the building occupants from the signaling floor and the priority evacuation floor to the evacuation assistance floor during the emergency condition.
- the information defining the emergency evacuation assistance floor and the signaling floor is included in the vertical transportation system's status signal sent to the remote communication system.
- Another embodiment of the invention is an evacuation control system having an elevator controller that controls the activities of an elevator car during a building fire or other emergency situation for reliable and continuous elevator operation during the emergency situation.
- the elevator controller for each elevator car is operationally connected to the signal control system.
- the signal control system is a central fire alarm panel.
- the elevator controller is programmed to position the elevator car in selected locations in the emergency evacuation zone during an emergency situation, so as to aid in the emergency evacuation of the building occupants.
- a smoke detector or preestablished compilation of sensing devices sends the building into an alarm state, thereby initiating the closing of fire doors and dampers, and starting the air handling equipment to provide positive pressure in the vertical shafts and enclosed elevator lobby areas.
- other building systems such as emergency suppression systems (i.e., sprinkler system).
- emergency suppression systems i.e., sprinkler system
- source-identifying alarm signals from the sensing devices are received by the signal control system, the signals are sent to a central processing unit, translated, and sent to the elevator controller, which is programmed to respond to these distinctive signals.
- Status signals from the building systems such as the fire doors and dampers and air handling equipment, are also provided to the signal control system and sent to the remote communication system.
- the elevator controller is programmed to identify a first signaling floor, e.g., the floor from which the alarm signal is generated, as the probable fire floor.
- the elevator controller is also programmed to define and designate an emergency evacuation zone within the building relative to the first signaling floor (i.e., the fire floor).
- the emergency evacuation zone is defined by the probable fire floor, the two floors above the fire floor, and one floor below the fire floor.
- the elevator controller is also programmed to provide evacuation priorities, wherein the first priority is evacuation of the fire floor, and the second priority is evacuation of the floor directly above the fire floor.
- the third priority is evacuation of the floor directly below the fire floor, and the fourth priority is evacuation of the floor two floors above the fire floor.
- the elevator controller is also programmed to establish a rescue assistance floor at a selected location away from the fire floor, such as four floors below the fire floor.
- Information defining the priority evacuation floors and the rescue assistance floor is provided to the signal control system and sent to the remote communication system. Accordingly, the elevators are used to evacuate the building occupants to the rescue assistance floor during the emergency situation, wherein the occupants can be attended to by emergency personnel and evacuated from the building if required. Status information regarding such evacuation is provided to the emergency personnel even before they arrive at the building.
- the elevator controller positions the elevator car or cars at the first signaling floor in a ready state with the car and hoistway doors in an open position. Only the hall call stations in the emergency evacuation zone are operable, and the other hall call stations are deactivated. The hall call stations within the emergency evacuation zone provide a visual notification of the emergency evacuation status by continuously blinking the down button. Audible notification is given by the continuous intermittent sounding of the elevator car arrival bell. A fan located in the elevator car is energized to blow tenable air from the hoistway shaft through the open doors thereby preventing smoke from entering the elevator car.
- the elevator controller closes the elevator doors, moves the elevator car to the predetermined rescue assistance floor, and opens the doors to allow egress out of the car.
- the elevator cars are equipped with a recorded-voice enunciator that provides audible instructions to reinforce the egress activity. After the occupants exit the elevator car, the elevator controller closes the doors and repositions the elevator car at the first signaling floor as described above, and awaits a call signal from a floor within the emergency evacuation zone.
- the elevator controller moves the car from the first signaling floor to the calling floor and opens the car and hoistway doors, thereby allowing the occupant to enter the elevator car.
- the elevator controller then closes the doors, moves the elevator car to the rescue assistance floor, and opens the doors to allow the occupants to exit the car.
- the elevator car is then returned to the first signaling floor and awaits another call signal.
- the smoke detectors throughout the building are polled by the signal control system. If a 10
- a signal is provided to the signal control system, e.g., the central alarm panel, and the central alarm panel notifies the elevator controller.
- the signal is also provided to the signal control system and can be provided to the signal control system and can be provided to the remote communication system to inform emergency personnel about the status of the emergency.
- the elevator controller also de-energizes the hall call station on the floor where smoke was detected in the elevator lobby and prevents the elevator car from opening its door when on that floor.
- the smoke detectors continue to be polled and if smoke is detected within the hoistway shaft or at the elevator car, the elevator controller automatically recalls all elevators traveling within the hoistway to the main lobby floor. At this time all hall call stations and car buttons are de-energized.
- the fire department can override the emergency evacuation sequence from the main lobby or the central fire alarm panel and recall the desired number of elevators to the main lobby.
- the fire department can designate additional evacuation floors thereby increasing the size of the emergency evacuation zone, and if desired, to eventually include all floors within the building.

- a conventional load sensor is attached to the motion controller 72 and is operatively connected to the elevator communication system 18 and to the elevator controller 16.
- the elevator controller 16 is programmed to evaluate the available load capacity of the elevator car 20 by determining a live load weight within the car as established by the load sensor and comparing this weight to the predetermined total live load capacity of the car. As the elevator car 20 responds to the activation of hall call stations 104 within a run, the car will stop at signaling floors until the safe operating capacity of the car has been reached, at which time the elevator car will not respond to additional signaling hall call stations.
- the elevator controller 16 When a live load weight exceeds the capacity, the elevator controller 16 activates the audible car notification device 96 and does not permit the motion controller 72 to energize the door motion controller 130. After the load sensor indicates a live load below the safe operating capacity, the elevator controller 16 de-activates the audible car notification device 96 and allows the motion controller 72 to energize the door motion controller 130.
- the elevator controller 16 is preprogrammed to respond to additional hall call stations 104 that are activated in the traveling direction while the elevator car 20 is traveling to one of the desired floor 21. Once the elevator car 20 has reached the furthest activated hall call station 104, the elevator controller 16 deactivates all activated floor destination buttons and reverses the car's travel direction.

- the elevator recall switch 186 may be automatically activated, such as when a detector 22 is activated.
- the elevator recall switch 186 may also be manually activated, such as during a non-fire emergency.
- the elevator recall switch 186 provides a signal to the elevator controller 16, which de-activates all hall call stations 104 and destination buttons 86 in all elevator cars 20 and energizes the motion controller 72 to move all elevator cars to a predesignated recall floor 188, typically established as the ground floor with a ready exit from the building 2.
- a recall floor smoke detector 190 is strategically located at the predesignated recall floor 188 and connected to the elevator communication system 18, which is operatively connected to the elevator controller 16, as described above.
- the recall floor smoke detector 190 detects smoke, a distinctive signal is sent to the elevator controller 16 which energizes the motion controller 72 to move the elevator cars 20 to a predesignated alternate recall floor 192, typically established as a floor located two floors above the ground floor.
- the fire alarm panel 26 polls and monitors the smoke/fire detectors 22 and selected other building systems. As best seen in Figure 5, in the event of a building fire, smoke or heat from the fire is detected by one or more detectors 22, the detector sends a distinctive first alarm signal 200 to the fire alarm panel 26.
- the first alarm signal 200 is transmitted by the fire alarm panel 26 through the interconnection communication system 10 to the CPU 38 and translated by the BACnet protocol language, thereby initiating an emergency elevator evacuation sequence 194.
- the components of the building egress system 4 of the exemplary embodiment, as described herein and schematically illustrated in Figure 2 work together in an emergency elevator evacuation sequence that utilizes the one or more elevator cars 20 to evacuate selected portions of the building 2.
- the interconnection system's CPU 38 is engineered and programmed to initiate a preprogrammed emergency elevator evacuation sequence.
- the CPU 38 sends distinctive output signals to the elevator controller 16 in response to distinctive input signals received from the fire alarm panel 26.
- the elevator controller 16 strategically positions one or more elevator cars 20 at selected floors to evacuate portions of the building 2.
- the CPU 38 also sends distinctive output signals to the fire alarm panel 26 in response to distinctive input signals initiated by the elevator controller 16, thereby notifying the fire alarm panel 26 of the status of all elevator cars 20. As discussed in greater detail below, the fire alarm panel 26 also contacts the fire department or other remote emergency response team and provides information as to the current status of the building 2. The emergency evacuation sequence is then initiated.
- the Emergency Evacuation Sequence establishes an emergency evacuation zone 202, as best seen in Figure 1, encompassing a four floor area around a first signaling floor (FSF) 206 on which a first signaling remote smoke/fire detector 204 of the detectors 22 is located.
- the first signaling floor 206 is assigned by the CPU 38 a first priority during the evacuation of the emergency evacuation zone 202.
- the emergency evacuation zone 202 also includes a second evacuation priority floor 208 located one floor above the first signaling floor 206, a third evacuation priority floor 210 located one floor below the first signaling floor, and a fourth priority evacuation floor 212 located two floors above the first signaling floor.
- the emergency evacuation zone 202 also includes an evacuation assistance floor 214 located four floors below the first signaling floor 206.
- the floors 21 outside the emergency evacuation zone 202 are 20
- the evacuation assistance floor (EAF) 214 is established as the predesignated recall floor 188 (usually the ground floor).
- the configuration of the emergency zone 202 may be changed depending upon air flow direction in the hoistway shaft 42.
- an air flow sensing device 216 shown in Figure 1, is mounted in the hoistway shaft 42, and is operatively connected to the CPU 38 of the interconnection system operator 34.
- the air flow sensing device 216 identifies the direction of air flow in the hoistway shaft 42.
- the air flow sensing device 216 has an upper sensor 218 connected to the wall structure 50 of the hoistway shaft 42 near the upper limit 44 thereof and a lower sensor 220 connected to the wall structure 50 of the hoistway shaft 42 near the lower limit 46 thereof, each operationally connected to the interconnection communication system 36.
- the emergency evacuation zone 202 is as described above. If, however, the airflow is downward, so smoke would travel downwardly toward lower floors, the CPU 38 is programmed to reverse the order of floors in the emergency evacuation zone 202 described above. Accordingly, the evacuation assistance floor 214 is located four floors above the first signaling floor 206.
- the second evacuation priority floor 208 is one floor below the first signaling floor 206
- the third evacuation priority floor 210 is two floors below the first signaling floor
- the fourth evacuation priority floor is one floor above the first signaling floor.
- the evacuation time is therefore relative to elevator travel within this six floor zone and not relative to elevator car travel within the entire height of the building 2.
- the detector When one of the detectors 22 detects smoke or the like, as best schematically illustrated in Figure 5, the detector sends a first alarm signal 200 to the interconnection system operator's CPU 38, and the CPU initiates the emergency elevator evacuation sequence 194.

- the elevator 21 the elevator 21
- the controller polls the hall call stations 104 of the floors in the emergency evacuation zone 202, and in step 226, deactivates all hall call stations of floors outside of the emergency evacuation zone.
- the elevator controller further energizes the down direction light 114 in the hall call stations 104 located within the emergency evacuated zone 202 to blink in a continuous intermittent manner.
- the elevator controller 16 further deactivates all destination floor buttons 86 in the elevator car 20.
- the elevator controller 16 also polls in step 232 the car status and determines in step 234 if the elevator car 20 is moving. If the elevator car is not moving, in step 236 the elevator controller 16 sends a distinctive signal to the motion controller 72 which in step 238 moves the elevator car to the first signaling floor 206.
- the elevator controller 16 initiates an evacuation-ready mode in step 240 in which the hoistway and car door assemblies 56 and 68 are moved to the open position, the down direction light is intermittently blinked, and the car arrival notification device 122 is energized to ring in a continuous intermittent manner. If the elevator car 20 is moving, in step 242 the elevator controller 16 polls in step 244 the car's direction of travel.
- step 246 the elevator controller 16 polls in step 248 the elevator car's location relative to the evacuation assistance floor 214. If in step 250 the elevator car is above the evacuation assistance floor 214, the elevator controller stops the car's ascent in step 252, in step 254 energizes the car destination button 86 for the evacuation assistance floor 214, and in step 256 moves the car to the evacuation assistance floor.

- step 280 the elevator controller 16 closes the hoistway and car door assemblies 56 and 68, in step 282 moves the elevator car from the first signaling floor 206 to the evacuation assistance floor 214, and in step 284 initiates the ingress/egress cycle to allow the passengers to exit from the car.
- the elevator controller in step 286 then moves the elevator car back to the first signaling floor 206 and in step 240 restarts the evacuation-ready mode of step 240.
- the elevator car 20 remains at the first signaling floor 206 for a predetermined amount of time, such as thirty seconds, in the evacuation-ready mode.
- step 288 a car button 86, 88, or 90 is not manually or automatically activated within the predetermined amount of time, the elevator car is then available to respond to the activation of hall call stations 104 on other floors within the emergency evacuation zone 202.
- step 290 a hall call station 104 is activated on another floor within the emergency evacuation zone 202
- step 292 the elevator controller 16 closes the hoistway and car door assemblies 56 and 68 and moves the car to the floor on which the hall call station was activated.
- the elevator controller then initiates the evacuation-ready mode of step 240, as described above. If hall call stations 104 are activated on more than one floor in the emergency evacuation zone 202, the elevator controller 16 moves the elevator car to the floor having the highest priority of the second evacuation priority floor 208, the third evacuation priority floor 210 or the fourth priority evacuation floor 212.
- step 294 a passenger activates a car destination button 86 or if the load sensor detects additional weight in the elevator car within the predetermined 23

- the elevator controller in step 280 closes the hoistway and car door assemblies 56 and 68, in step 282 moves the elevator car to the evacuation assistance floor 214, and in step 284 initiates the ingress/egress cycle.
- the elevator controller in step 240 then moves the elevator car 20 back to the first signaling floor 206 and initiates the evacuation-ready mode.
- step 296 the elevator car is in the evacuation-ready mode of step 240 on a floor other than the first signaling floor 206 and a destination car button 86 is not manually or automatically activated within the predetermined amount of time
- the elevator controller 16 in step 298 closes the hoistway and car doors 56 and 68, in step 300 moves the car back to the first signaling floor 206, opens the door assemblies, and initiates the evacuation-ready mode of step 240.
- the elevator car remains in step 288 in the evacuation-ready mode of step 240 on the first signaling floor 206 until a car button 86, 88, or 90 is activated, or in step 290 the load sensor detects additional weight within the car, or a hall call station 104 within the emergency evacuation zone 202 is activated.

- a signal is sent to the CPU 38 where it is translated and sent to the elevator controller 16.
- controller 16 in step 312 then deactivates the hall call station 104 on the floor where the lobby smoke/fire detector was activated, thereby preventing the car door assemblies 68 from opening at that floor. As a result, the occupants on that floor must use the stairway for evacuation to the evacuation assistance floor 214.
- audible recorded instructions are played over the recorded-voice enunciator system so as to provide instructions to occupants to proceed to the stairwell for evacuation, because the elevators are out of service.
- the car smoke detector 176 detects smoke or in step 178 the hoistway smoke detector 178 detects smoke, in step 314 that smoke detector sends a third distinctive detection signal to the fire alarm panel 26, which sends the signal to the interconnection system operator's CPU 38.
- the CPU 38 translates the signal and sends it to the elevator controller 16.
- the elevator controller 16 in step 316 then initiates an emergency recall sequence in which all hall call stations 104 and car destination buttons 86 are deactivated and all cars are moved and parked at the predesignated recall floor 188.
- the elevator controller then powers down, thereby taking the car out of service.
- Audible instructions are played over the recorded-voice enunciator on the floors of the emergency evacuation zone 202 to proceed to the stairwells for evacuation, because the elevators are out of service. All remaining building occupants must await the arrival of the fire department for rescue or use the building exit stairways for evacuation.
