Definitions

  • the invention relates to a method for controlling an elevator installation, the a passenger transporting between floors of a building Elevator car has.
  • the procedure provides that the travel wishes of the Passengers entered via a destination call control and from the destination call control be posted as destination calls.
  • a present in the elevator car instantaneous load of a load measuring device determined.
  • the invention further relates to an elevator installation, those with an elevator car, one in the elevator car instantaneous loading measuring device and a destination call control, by means of the travel wishes of passengers to be transported can be entered and booked as destination calls provided.
  • EP 0 301 173 A1 describes a group control for elevators, having a monitoring circuit, which the allocation of a Destination call to an elevator with overload prevented. It is however of a careful input of destination calls, since the overload based on the booked passengers.
  • the present invention has for its object to avoid the above problems with faulty operation of the destination call and to provide a method for controlling an elevator system and a lift system, with which the transport time optimize and maximize the transport capacity.
  • This object is achieved in a method for controlling an elevator system with the above features according to the invention in that the instantaneous load is compared with a full load parameter and is activated when exceeding a bypass function of the full load.
  • the bypass function is activated for floors for which destination calls are booked and which are still passed during a half round of the elevator car.
  • a half-round in the sense of the present invention is understood to mean a travel of the elevator car between the reversal points of the elevator car.
  • the invention is based on the idea that shock times in a predominantly downslope, also referred to as down-peak traffic, only occur at certain times. With the method according to the invention will be in these rush hours even with possibly faulty operation the destination call control uniform waiting times and an optimized Utilization of transport capacity achieved.
  • the bypass function is Ensures that a fully loaded elevator car directly to the next Drop-off destination drives and destination calls from passengers arriving in intermediate floors wait to be moved to a next elevator semis.
  • Advantageous embodiments of the method according to the invention are the Claims 1 to 8 and the elevator installation according to the claim 10 to remove.
  • the elevator car is at activated bypass function the floors for which from the destination call control booked destination calls are present and on which passengers of the semicircles do not want to get on until the moment load returns below the full load parameter. This will make it a full loaded elevator car on direct way from the higher floors to the ground floor or to a main hold floor drives without on already stop booked floors and thus waste transport time.
  • a priority half-round be moved with the same direction, preferably the Priority half-rounds from the elevator car following the first half-round is traversed. This will accomplish that upon arrival of the fully loaded Elevator cabin on the ground floor or on the main floor the elevator car goes directly to the upper floors and the Picking up passengers who were already assigned to this lift and due the fully loaded elevator car at the first downlink round not could be transported.
  • the elevator after serving all before the onset of the crossing of the full load parameter booked destination calls in a normal mode (operation without bypass function). This ensures that only after all non-promoted passengers from floors due to the bypass function were not approached, in the ground floor or in the main hold floor are transported to the elevator of the destination call control newly entered destination calls can be assigned again.
  • the measurement of the instantaneous load is advantageously at the time of Doors closed. Thus it is achieved that no change the load of the elevator can adjust more, so that at the Comparison of the instantaneous load of the elevator car with the full load parameter no errors can occur.
  • a number vacant seats from the outgoing and incoming booked by destination call control Passengers are charged, with the elevator car one floor only starts when the number of free seats is greater than the number of free seats Destination calls from passengers to boarding in the semi-round to be passed Floors is.
  • a counter which counts the launches of elevator car travel, in which the Instantaneous load is greater than the full load parameter.
  • the bypass function is in Such an embodiment is activated only when a predetermined, adjustable value for the maximum number of such Vollastfahrten exceeded becomes.
  • the value of the counter is decremented.
  • This will be an activation the bypass function avoided if it is not absolutely necessary to For example, if a fully loaded elevator car only accidental and not occurred within predetermined time periods or in typical situations is.
  • the activation of the bypass function be monitored by a period of time, the time being shared with the value of the counter for activation and / or deactivation the bypass function is used.
  • the time span for example set to 5 minutes
  • the value of the counter to activate the bypass function is periodically decremented every 2 minutes, for example.
  • the Bypass function is not deactivated until both the time span of 5 Minutes, as well as the value of the counter by the periodic Decrement below a value to activate the bypass function and no priority half rounds exists anymore.
  • the Activation of the bypass function is made at a counter value, the is greater than the value for deactivating the bypass function. In this way a hysteresis function is achieved, which is a non-beneficial back and forth Switching between activated and deactivated bypass function avoids.
  • the elevator installation comprises a group of elevators, with the bypass function for each Elevator of an elevator group can be activated separately, so that the to be inserted Priority half rounds for the carriage of those not transported Passengers on the unused floors of the concerned Lift alone or operated.
  • the bypass function for all elevators belonging to a group activated together with only a part of the lifts for the operation of the not approached floors with the waiting passengers during the Priority half rounds is used.
  • the others belonging to this group Elevators can therefore already work in normal mode again, or you can still work in the bypass function by using the Floor, in which the overload has occurred, is preferably operated.
  • Fig. 1 is schematically the problem of a faulty operation of Destination call control shown.
  • Fig. 1 symbolizes 18 floors of a building.
  • half rounds HR1 to HR5 are shown by arrows.
  • An elevator car EC is in floor 15. The following situation is conceivable to explain the problem.
  • Fig. 2 shows schematically the inventive method. It is again 18 floors shown, the elevator car EC is located in the Floor 15. The number of passengers is the same as in the previous one Fig. 1 illustrated example.
  • the bypass function activated, which the destination calls of the passengers in the floors 8 and 6 in the next priority half round HR3 and the up call of Floor 12 on floor 15 from the semicircle HR2 in the semicircle HR4 shifts. Also all newly entered destination calls, for example in Floor 10, according to the semicircles HR4, PHR5 after the Priority half circle PHR3 postponed.
  • the elevator car EC moves in Following the unloading of passengers in floor 1 upwards in the Floors 8, 6, 5 to carry the passengers due to the bypass function were not promoted on the first half-round HR1.
  • the passengers in floor 12 will be in the next upward round HR4 in the floor 15 transported. Only after all forgotten passengers carried are, later input destination calls from the floor 10 are taken into account. When allocating new destination calls, any further lifts will be used Lift system help to defuse the situation.
  • the deactivation of the bypass function can also be time-controlled become. For this purpose, a period TDP and the value CFLDP is used. The period of time TDP begins after the first time the full load parameter is exceeded to run. It can also be provided that the time span TDP only after the first start, in which the moment load of the elevator car EC is less than full load, starts to run.
  • the bypass function will However, only then deactivated, if in addition the value CFLDP a has reached predetermined value DPOFF. In this example, the value becomes CFLDP of the counter is periodically decremented.
  • bypass function can cause hysteresis in the values DPON and DPOFF to enable or disable the bypass function be implemented.
  • the above-described method for controlling an elevator system records by a tolerance against a faulty operation in the destination call control out. This is primarily due to the bypass function, which prevents a fully loaded elevator car during a Semi-circular HR stops on floors 8, 6, 5, for which destination calls are booked, but due to the loading of the elevator car EC no passengers can get in.
  • the method thus contributes to an optimized utilization the transport capacity of the elevator car EC and ensures In addition, a speedy transport of passengers.
