Definitions

  • the invention relates to an evacuation system for lifts in objects, in particular in buildings, structures, high-rise buildings, underground train stations, shopping centers, tunnel structures, industrial complexes or ships, wherein a device for hazard reporting is connected to an elevator control which, in the event of danger, evacuates a predetermined trip Emergency stop station triggers.
  • the invention further relates to a method for controlling elevators in objects in the event of danger.
  • Elevators that are in operation when an alarm is triggered are particularly problematic here because, for example, the exits of the elevators, ie the elevator doors and the corresponding vestibules, cannot be used due to fire. There is also the risk that the proper function of the elevators is no longer ensured due to the effects of fire, for example.
  • a fire alarm is activated internally in the event of a fire, which controls the elevator to a floor specified by the fire service, in the case of high-rise buildings generally the ground floor, opens the door and then locks the elevator control.
  • the purpose of this measure is the resulting possibility for the arriving fire department to be able to control all the lifts on one level.
  • the ground floor is chosen as the fire stop so that the people in the elevators can quickly escape to the outside.
  • the elevator In the case of a fire, the elevator always moves to the bottom floor in accordance with the Elevator Ordinance in order to keep the hydraulic lines free of pressure and prevent the cabin from dropping if pressure is lost due to fire.
  • the elevator control also has a hazard control, which exclusively takes over control of the elevator when a hazard signal is received from the device for hazard reporting and controls the elevator to a safe stop as a function of the hazard signal.
  • the device for hazard reporting is preferably a fire alarm system and / or smoke detectors, so that any existing systems can be modified accordingly.
  • the evacuation system can also be retrofitted in existing objects or buildings.
  • the security of the system is additionally increased in that additional smoke detectors are arranged on elevator doors and / or elevator door vestibules and are connected to the elevator control; optical sensors are provided on elevator doors, the maximum spectral sensitivity of which lies outside the absorption spectrum of smoke arising in the event of a fire; and the optical sensors are infrared light barriers, in particular infrared laser light barriers.
  • an additional push-pull circuit is advantageously provided on the elevator doors, which forcibly closes the elevator doors while excluding the risk of injury to persons. Additional safety and flexibility is provided by a manual door closing switch provided in the elevator, which has a higher priority than door sensors in the event of danger.
  • Adequate interference immunity over at least a predetermined period of time after the alarm is triggered is achieved in that all lines and devices belonging to the hazard control and controlled by it in the event of an emergency are designed for at least 30 minutes of functional maintenance after the occurrence of a hazard signal. Furthermore, it is advantageous if all the lines and devices belonging to the danger control and controlled by it in the event of danger are connected to network substitutes for energy supply in the event of a power failure and optionally additional main power supply lines of the elevator are equipped with smoke detectors throughout.
  • display means are provided at at least one emergency stop, in particular the highest priority emergency stop, which display the current location of the elevator.
  • step (e) blocking the emergency stop set in step (c) in the list of emergency stops and repeating steps (c) and (d) if the result of step (d) is positive, and
  • the evacuation process is advantageously supported and accelerated.
  • an announcement is made which prompts the user to leave the elevator and use the escape routes located nearby.
  • step (d2) Setting a predetermined emergency stop, in particular the highest priority emergency stop, and proceeding to step (f) if the result of step (dl) is positive.
  • the rescue and aid personnel are supported in that a current elevator location at the danger emergency stop with the highest and / or second highest priority is displayed.
  • step (f) it is advantageous if an evacuation trip is not carried out or a lift trip that is just beginning is not permitted. This takes into account the following additional steps before step (f) and / or step (b):
  • step (e2) Set the elevator to an “out of operation” state and, if necessary, open elevator doors at the moment the elevator stops, if the result of step (el) is negative.
  • step (f) A minimization of the travel time of the evacuation trip and an increase in safety is achieved in that in step (f) all stop requests on one route are ignored while the elevator is traveling to the emergency stop set.

  • Additional smoke detectors 40, 42, 44, 46, 48 and 50 are arranged in each of the floors 28, 30, 32, 34, 36 and 38 and are connected to the hazard control unit 20 via signal lines 24. A signal on at least one of these signal lines 24 activates the hazard control 20, which then deactivates the elevator control 18 and takes over the control of the elevator 12.

If necessary, the loop of the Steps 66, 70, and 82 are set as a safe stop.
  • step 78 in that all stops in the list 90 are blocked. If this is the case, the method continues with step 80, in which, regardless of the block in list 90, a predetermined stop is set and subsequently in step 72 the evacuation trip with the final steps 74 and 76 takes place.

  • the new evacuation system stipulates that all elevators that cross several fire compartments perform a dynamically controlled evacuation trip in the event of an evacuation of a building or some parts of a building.
  • the aim of the dynamic evacuation trip is to immediately move the elevators to a specified floor that is not affected by the fire, on which the people in the elevators can reach a safe staircase or the open space by the shortest route.
  • the dynamic evacuation trip can be carried out using a fire alarm system (BMA) or an additional one Cabin doors 29, 31, 33, 35, 37, 39 installed smoke detectors 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50 are triggered.
  • BMA fire alarm system
  • the control of the elevators is modified in such a way that in the event of a fire alarm triggered by the BMA or if there is no BMA from smoke detectors installed on each floor, a predetermined floor, the fire stop (BFH), is automatically approached.
  • the car doors are opened and the elevator goes into the "Out of service” state with the doors open. The doors must remain open so that the location and condition of the elevator can be seen immediately by the fire brigade without having to open the cabin door with heavy tools when looking for injuries.
  • the location of the fire stop must be determined in individual cases, since the risk of a drop in pressure loss is estimated to be lower than the elevator ride to a smoky floor.
  • the pressure loss to be expected in the system is secondary here, since if the hydraulic lines are appropriately exposed to fire, no escaping people are to be expected. If the elevator sinks slowly later due to a leak caused by the fire, there is no longer any risk to people. Possibly. the locking valve, which is located as close as possible to the hydraulic ram, has been designed to be fire-protected.
  • the dynamic evacuation run is always carried out when a fire message comes from the BMA, ie the lifts that are waiting on any floor close the doors and move to the fire stop, usually the ground floor. If the source of the fire is on the ground floor, the elevator stops on the next smoke-free floor above. For example, the EBFH's priorities are distributed automatically from bottom to top, so that the elevator always only keeps a minimal number of levels from the ground floor.
  • the separating feature is the completely closed car door (limit switch) in conjunction with a pressed one-touch dial button, i. H. If this state has not yet been reached when the fire message arrives, the door opens again and the elevator goes into the "Out of service" state with the door open.
  • the optical sensors (light curtains or light barriers) for controlling the cabin door should have their maximum spectral responsiveness outside the absorption range of the smoke that arises in the event of a fire (e.g. infrared light barriers), so that the cabin door can be closed at all times even in the event of heavy smoke .
  • the power of the transmitting elements must be increased compared to conventional systems (IR laser instead of IR LED, avoidance of reflex light barriers).
  • the PIR motion detector installed in some elevators on the cabin door has the same function as the light barrier; it should prevent the door from closing if there is movement in front of the cabin door within a distance of approx. 2 m (e.g. wheelchair users).
  • the detector has the same priority as the light barrier. Since the PIR detector would be affected by heat radiation in the event of a fire and the cabin door could not be closed, the detector must also have a lower priority when the fire switch is used.
  • a jostle switch multiple closing attempts with reversal of movement
  • the cabin door can be closed with "gentle force" in the event of a fire, bypassing the light grids and the motor current limit, without the risk of injury to persons.
  • the pushbutton for closing the door that is already on the control panel in some elevators can be provided with a higher priority than the light barrier and motion detector in an evacuation trip, so that the door can be closed immediately in an emergency, whereby the protection of any people standing in the door must be taken into account (e.g. no-time jostling). If this button is not available, it can preferably be retrofitted.
  • an automatic announcement is made via the cabin loudspeaker when the elevator is switched off or when the fire stop is reached, with the request to exit the elevator and information on using the safe staircase or emergency exit.
  • the main power supply lines to the operating room of the passenger lifts should be monitored area-wide by smoke detectors, which also trigger an evacuation trip, because if the power supply is interrupted, an evacuation trip is no longer possible and the elevator between the floors can remain in the shaft. In this case, a hazard to people in the elevator from smoke rising in the elevator shaft cannot be ruled out.
  • the respective location and the condition of the elevators are preferably visually marked on a circuit diagram or monitor so that in the event of a fire, the fire brigade can immediately see whether all elevators have performed the dynamic evacuation run properly or whether further measures are required .
  • floor indicators are preferably arranged on the outer cabin door, so that the fire department on site is always informed about the location of the lift without any questions at the central office if the lift has moved to a replacement fire stop or another one Floor stands.
  • Escalators and conveyor belts or moving walks stop slowly when there is a smoke alarm in the assigned fire compartment so that they can be used as an escape route in both directions of movement and tripping of walking people at the end of the conveyor belt or stairs is avoided. It must be ensured that the belts cannot start up again automatically.
  • a dynamically controlled evacuation trip of elevators in the event of a fire enables safe and quick evacuation of people within a few minutes after the first fire report to a structurally secured fire stop.
  • By passing on the information about the source of the fire from the BMA to the elevator control it can be reliably prevented that the elevator stops on a smoky and fire-affected floor and opens the doors.
  • After reaching the BFH the people in the elevator are prompted via an automatic announcement to leave the elevator.
  • Function maintenance and monitoring of the feed lines of the elevator guarantee reliable functioning of the dynamic evacuation run in the event of a fire.
