Definitions

  • the invention relates to a safety device for a multimobile elevator group, the collisions between several lifts operating in a shaft prevented.
  • EP 595 122 discloses an elevator installation with several Wells became known in which several vertical and horizontally self-propelled passenger transportation systems can run in the same shaft. Every cabin can horizontally from one shaft to another shaft drive and is with its own drive, for example provided with a friction wheel drive, the friction and Roll the guide wheels in the shaft corners. Every cabin also has an autonomous management control the cabin or destination calls, for what purpose the distance to a possibly above or below yourself located cabin is measured. In addition, as Security against overspeed or in the event of a crash The truck's lift truck is a common safety gear intended.
  • the invention has for its object a Safety device for a multimobile elevator group to propose of the type mentioned at the outset Collisions between those in the same shaft Cabins prevented.
  • the advantages achieved by the invention are in essential to see that through optimal Adjustment of the distances between the cabins using the Safety device the performance of the Multimobile elevator group can be fully used and that the security module is designed redundantly, so that the elevator system is not just one Security module must leave.
  • Safety device specified in claim 1 for a Multi lift group is particularly suitable Safety device for self-driving cabins. Furthermore, by arranging a Safety module on each cabin, other cabins, for example one following in the same shaft, monitor and trigger an emergency stop if at monitored cabin malfunction occurs.
  • FIG. 1 shows a schematic representation of a Multi-mobile elevator installation.
  • Several vertically and horizontally self-propelled elevator cars C1..CN run in one Elevator system with, for example, four shafts 1 and Floors E1..EN.
  • Each cabin C1..CN is of one own independent drive 1, for example from a frequency-controlled drive driven. Execution can, for example, in the form of EP 556 595 described friction wheel drive take place.
  • the bays 1 are at their upper and lower ends each with a connecting passage 3 connected with each other. This way the cabins C1..CN by changing the shaft in the direction of travel to change. A change in the direction of travel can also take place if there is only one cabin C1..CN in one Slot 1 is located.
  • a communication system 11 secures the Transmission of information between the elevator cars C1..CN and the security module 10.
  • the Security device further includes within the Security module 10 a decision module 12, which is responsible for determining the stop commands.
  • the decision module 12 continuously receives the Positions, speeds and stopping options from all cabins C1..CN.
  • the cabins C1..CN also send a stop request that decision module 12 processed and the cabin C1..CN the stop permit granted.
  • the normal stop for example, is one frequency-controlled drive controlled by the torque.
  • Holding brake for example, uses a drum brake.
  • the safety gear arranged directly on the cabin can be designed, for example, as a roller catching device.
  • a constant flow of data with the positions, Speeds and targets of the cabins C1..CN would need an infinite communication channel. For this The reason becomes a dynamic one in the security module 10 Integrated elevator model.
  • This model allows a very fast transmission of driving data (positions, Speeds and destinations) and enables that Decision module 12 an immediate determination and Transmission of stopping commands to cabins C1..CN.
  • the target floor allocation is restricted so that unnecessary stops and between floors E1..EN blocked cabins C1..CN can be avoided.
  • FIG. 3 shows a deceleration curve D for elevator cars C1..CN.
  • a cabin C1 drives through shaft 1 with the Nominal speed vn.
  • the drive control follows to be able to stop E1..EN the predetermined deceleration curve D, within one certain tolerance band Z, from the beginning of the delay with Nominal speed vn at point A to standstill vs the cabin C1 on the desired floor E1..EN at Point F of the deceleration curve D.
  • starts the cabin C1 from a point B closer to point F cannot be accelerated to the nominal speed vn, otherwise the cabin C1 is no longer used by the passengers reasonable delay values brought to a standstill can be.
  • the drive control follows Reaching point C of the deceleration curve D by Standstill vs at point F.
  • Fig. 4 shows a dynamic model of the elevator driving curves for a building with five floors f1-f5.
  • the deceleration curve D shown in FIG. 3 becomes the driving curves for all possible floor distances, accelerations and delays are shown in the dynamic model.
  • Selectors s i, j are the intersections between the Acceleration curves from the starting floors i and the Delay curves to the target floors j.
  • the point f k is the stop position on floor k.
  • the Information from all selectors and stop positions f form the transition period between these points the dynamic model of an elevator system.
  • Knowing the location of a relevant point Cabin C1..CN in the network is synonymous with that Knowing the current positions and speeds. This allows the future positions to be determined and the stopping options of the cabins C1..CN. Therefore a cabin C1..CN only needs the position of a certain one Brand on the network to view all of the Decision module 12 transmit the requested information to be able to.
  • Such a message can take the following form, for example: ! 365.4 C1 s3.4
  • Fig. 5 shows a schematic representation of the possible Braking behavior and the stopping commands of a cabin.
  • the the stop commands are sent quickly and easily through the decision module 12. As the most important The command must stop f k in the component Network that the cabin C1..CN must reach contain.
  • a stop command can take the following form, for example: !! 370.1 C1 f5
  • This stop command instructs the cabin C1 that To reach floor f5.
  • the double exclamation mark ! indicates that it is a stop command.
  • the time specification 370.1 is optional. It corresponds to the maximum arrival time on floor f5. This will implicitly stipulates the braking behavior (normal stop N, Emergency stop E and safety gear P).
  • the additional information [E] describes this Braking behavior, in this case an emergency stop E to cabin To be able to stop C1 on floor f5.
  • the stop commands are set implicitly.
  • the Decision module 12 may be a stop for a cabin C1..CN long before arriving at a selector f k Arrange. Therefore, the decision module 12 of any real-time problems, such as the Commands for the brakes etc., detached. Every cabin C1..CN is responsible for monitoring its Position and speed. The cabins are the same C1..CN responsible for the initiation of the Braking phase or for deceleration control until final stop, whereby the decision module 12 sent stop commands is followed.
  • FIG. 6 and 7 show schematic representations of the Cabin conditions for the decision module 12.
  • the Decision module 12 must monitor the Elevator dimensions of the cabs C1..CN, especially know their heights h.
  • the cabin height h is determined by the decision module 12 as the length of the in Fig.7 shown bar is taken into account.
  • Brands T represent the States of the cabins C1..CN in the network Configuration as in Fig.6 would be between cabin C2 in Approach to floor f4 and cabin C1 at the Departure from floor f4 due to the overlap (hatched area) of the two cabins C1, C2 one Cause collision.
  • Such system states can from Decision module 12 predicted and effective be prevented.
  • FIG. 8 shows a schematic representation of the components for the entire safety device. All cabins C1..CN share the one shown in Fig.4 dynamic model, or each cabin C1..CN implemented the dynamic model into a module M1. Also owns each cabin C1..CN a security module 10. By the redundant version of the security module 10 is the Security increased significantly since the elevator system not just rely on a single security module 10 got to.
  • the elevator control 20 sends a Stopping module 21 the request to a receiver unit 22.
  • the current Driving data especially the cabin position and Speed, based on shaft information 26 and the information provided by a real-time clock 27, certainly.
  • Position and speed are in one Processing unit 28 with the dynamic model the module M1 and to an information unit 29 Posted.
  • the data are made the receiver unit 22 (stop request), the Information unit 29 (position and speed) and another dynamic model from a module M2 processed and the braking behavior determined.
  • the braking behavior Command generator 30 passed, which the Stop command generated. This stop command will transmitted to a brake module 31 of the cabin C1..CN, which for forwarding the command or the Initiation of the braking phase is responsible.
  • each Cabin C1..CN has the option of its Control the stopping process yourself.
  • every cabin C1..CN other cabins monitor and trigger an emergency stop if at monitored cabin C1..CN malfunction occurs.
  • Each cabin C1..CN has sensors at the top and bottom, for example, infrared sensors arranged the Distances to above and below in shaft 1 Measure existing cabins C1..CN.
  • To determine the Positions of the cabins C1..CN can be one Shaft information system serve, for example in the form of measuring strips arranged in the shafts 1, which by light barriers attached to cabins C1..CN be scanned. In this way, the Speed and position of each cabin C1..CN be determined.
  • These driving data are also on Pass security modules 10 and then the Braking behavior of the cabins C1..CN determined.
  • These safety devices are also on other than self-driving multi-mobile elevator groups applicable, For example, on an elevator group with several in the same shaft 1 cab on cables C1..CN run. As compensation organs are at the rope ends Counterweights arranged. With such an elevator group each cabin C1..CN has its own independent Drive that is in a machine room above or attached below the shafts 1 or on the counterweight is.
  • the arrangement of the security modules 10 does not have to be mandatory in cabins C1..CN; You can also in the machine room or on floors E1..EN be accommodated.
