Definitions
- the present invention relates to a method for operating an elevator system with a car, which is moved in an elevator shaft, wherein the car stops in a holding floor, wherein the holding floor is stopped on the holding floor, in the course of which an energy flow interruption and / or a service brake activation is carried out, wherein in the case of energy flow interruption, an energy flow of a drive of the car is interrupted and wherein in the case of service brake activation a service brake is activated and wherein readjustment on the maintenance floor readjustment of a car position of the car is performed, wherein in the course of readjustment the car position in the elevator shaft is adjusted relative to the holding floor.
- Point 12.7 of EN 81-1 concerns “stopping the drive and monitoring its stoppage". For example, according to point 12.7.3. ("Supply and control of three-phase or DC motors by static means") requires that "one of the following measures be Section taken: a) The flow of energy to the engine is interrupted by two independent contactors. If the main contactors of one of the two contactors do not open when the lift is shut down, a restart must be prevented at the latest at the next change of direction. b) A circuit consisting of
- Supporting cables to which the car is suspended constitute a spring system when the car is loaded. Cable lengths of the support cables may vary at different loads in the car change. If the load in the car increases (or decreases), the rope length of the suspension ropes may increase (decrease).
- Such a change in rope length during a stopping stop may result in unfounding of the car in which the car position of the car in the hoistway changes relative to the stopping floor.
- a step between the car door threshold and shaft door threshold may arise, ie a step between the floor of the car and the floor of the landing floor.
- the car position is regulated or readjusted relative to the holding floor. This can be done for example on the basis of an absolute positioning system. Such readjustment ensures, for example, that the step between car door threshold and landing door threshold does not exceed a permissible limit value.
- point 12.12 of EN 81-1 requires a stopping accuracy of ⁇ 10 mm and a readjustment accuracy of ⁇ 20 mm.
- a stop of a car lift is performed after a fixed predetermined sequence.
- the car is shut down.
- a service brake is activated and the power flow interruption is performed.
- the contactors are switched off accordingly and the drive is thus deactivated.
- the car position can be determined by means of position measuring sensors. If an unbalance is detected, the readjustment will be carried out.
- one must certain turn-on cycle are performed to re-activate the drive of the car.
- the contactors are initially controlled accordingly.
- a drive torque or engine torque of the drive is set according to a current loading of the car.
- the current load of the car is determined, for example by means of a load measuring sensor.
- the drive torque is adjusted accordingly.
- the service brake is released and the readjustment can be performed.
- the elevator system comprises a car which can be moved in an elevator shaft or a car which can be moved in the elevator shaft.
- the car stops in a holding floor. Under a stop, in particular, to understand that the car enters the holding floor and there performs an operational stop. In particular, a stop is the time interval between an arrival time at which the car enters the holding floor and a departure time at which the car leaves the holding floor. The car is stopped on the landing floor. In the course of this shutdown done an energy flow interruption and / or a service brake activation. In the case of the power flow interruption, an energy flow of a drive of the car is interrupted. In the case of service brake activation, a service brake is activated. In particular, first is the service brake activation and then the power flow interruption. Alternatively, the service brake can be activated without interrupting the power flow.
- a readjustment of a car position is carried out on the landing floor.
- the car position in the hoistway is adjusted relative to the hold floor.
- at least one operating parameter relating to a loading change of the car is detected.
- this at least one operating parameter is determined at least before stopping the car, if there is a need for readjustment on the landing floor.
- This at least one operating parameter relates or describes, in particular, a load change which will occur in the car during the stop of the stop.
- the readjustment can be carried out in particular before the car is shut down. Alternatively, the readjustment can also be carried out after the car has been shut down.
- the car position is regulated to a corresponding desired car position or holding position.
- the energy flow interruption is carried out in particular according to the initially explained standard EN 81, in particular according to point 12.7 of EN 81-1.
- the drive of the elevator system for example as a traction sheave drive may be formed, in particular via a convenient connection circuit connected to a power supply network.
- this connection circuit may comprise two independent contactors or, more particularly, a contactor, a control device and a monitoring device.
- a service brake is first activated and then the contactor or the contactors are switched off accordingly and the drive is thus deactivated.
- the elevator system should not be restricted to a car, but in particular may also be designed as an elevator system with a plurality of cars (generally referred to as "multicar system”).
- the elevator system can comprise two cars that can be moved in a common elevator shaft ("twin system").
- the invention and its embodiments are particularly suitable for each car of an elevator system with several cars.
- the readjustment and the power flow interruption can be optimally matched. Depending on the current situation or depending on the determined readjustment requirement, it is expedient to carry out first the readjustment and then the power flow interruption or vice versa. The same applies additionally or alternatively to the power flow interruption for the service brake activation, without this being explicitly mentioned below.
- the readjustment is performed before the power flow interruption.
- the drive is not deactivated before the readjustment has been completed.
- the power flow interruption is possible only once per stop and not unnecessarily often.
- the detection of the at least one operating parameter and the determination of the readjustment requirement are carried out prior to carrying out the holder stop, in particular before the car arrives in the holding floor.
- it is not only checked on the holding floor during the stop to stop whether the car position changes so much that a readjustment must be carried out. Instead, it is determined in advance before the halt stop, whether on the landing floor such a case will occur. Thus, it is determined as early as possible whether a readjustment will be necessary on the landing floor.
- the readjustment of the car is carried out before stopping in a determined readjustment.
- the drive remains initially active after the car enters the hold floor.
- a corresponding holding drive torque is set on the drive.
- the car position is regulated to a corresponding desired car position or holding position. Does that change? Car position due to the discontinuity or due to a corresponding load change in the car, the readjustment is performed automatically.
- the readjustment can be carried out automatically and as quickly as possible. The readjustment can thus be carried out with the greatest possible readjustment accuracy.
- the drive of the car does not have to be activated first from a deactivated mode. Furthermore, in particular, a switch-on cycle does not have to be carried out first before the readjustment can be carried out. Thus, no delay times have to be taken into account, with which individual steps of the duty cycle are connected. A delay time between detection of the Tinbillion and the carried out Nachregultechnik is thus considerably reduced.
- switch-on cycles of conventional elevator systems there is the problem that a drive torque can not or at least hardly be set precisely and that a jerky movement of the elevator car can occur when releasing service brakes.
- Control technology it is generally much more difficult to regulate a stationary drive to a desired car position, as to keep a running, active, controlled drive to a desired car position. Since the drive of the car can remain activated before a readjustment to be carried out, the readjustment can be carried out as gently as possible for the drive and brake components, precisely and with increased ride comfort. Since the drive is active and already adjusted before a readjustment to be carried out, "sets" or jerky movements of the car can be prevented. In particular, it is thus avoided that a step between the car door threshold and shaft door threshold or a step between the floor of the car and the floor of the retaining floor is created. A risk of tripping for passengers is best avoided.
- the readjustment can be started in this case, for example, immediately at the beginning of the stop after the car enters the hold floor.
- it can also be determined on the basis of the at least one operating parameter and / or on the basis of further operating parameters of the elevator system when the readjustment is started.
- these further operating parameters are detected, in particular, during the stop of the stop and, based on these detected operating parameters, it is determined during the stop of stopping when the readjustment is necessary and when it is started.
- a load and / or a load change in the car can be monitored as such further operating parameters. As soon as the load and / or load change exceed a predetermined value, it is assessed that the readjustment is started.
- the at least one operating parameter and / or on the basis of the further operating parameters it can be determined during the stop of the stop how long the readjustment is carried out. For example, once the load and / or load change in the car fall below a predetermined value, for example, it can be evaluated that the readjustment is terminated.
- the shutdown of the car can be carried out in this case, in particular immediately after the end of the readjustment.
- the power flow interruption and / or the service brake activation take place as soon as the readjustment is completed.
- After the end of readjustment Wait a certain time interval before the shutdown of the car is performed.
- an anticipated change in the loading of the car is determined.
- it can be determined on the basis of this probable load change, when the readjustment is started during the stop of the stop.
- it can also be determined how long the readjustment will be carried out.
- the car is preferably shut down after the readjustment has taken place in accordance with the anticipated change in load determined.
- the at least one operating parameter for determining the readjustment requirement is subjected to a threshold value comparison, in particular a limit value comparison. If the at least one operating parameter reaches a threshold value, it is determined, in particular, that a readjustment requirement exists.
- a first load change by which a load of the car in the hold floor is reduced, and / or a second load change, by which the load of the car in the hold floor is increased, determined as the at least one operating parameter.
- the elevator system or the elevator control for example, by destination selection control already known before the start of the stop, how many passengers leave or enter the car in the course of the stop.
- a corresponding load change can be determined or extrapolated.
- Such operating parameters are particularly suitable for passenger lifts. For example, in the case of freight or freight elevators, a freight which is loaded into or unloaded from the car in the course of the stop is determined as the corresponding load change or operating parameter.
- the readjustment is to be carried out if the first and / or the second load change exceed a respective limit value.
- these limit values are each chosen such that the unfitness or the change in the car position relative to the holding floor does not exceed a corresponding maximum value due to the corresponding load change. This prevents a step between the car door sill and the shaft sill, ie between the floor of the car and the floor of the retaining floor. Demanded standards can thus be met or even exceeded in terms of increased safety, since the control process can proceed much more dynamic.
- the readjustment at a start of the stop of stopping and the stopping of the car at an end of the stop of stop are performed.
- a point in time is to be understood, at which the regular stop of the car begins in the holding floor.
- the arrival time at which the car enters the stopping floor is to be understood as the arrival time at which the car enters the stopping floor.
- an opening time is understood to open the doors of the car.
- the end of the stop is a time at which the regular stop of the car in the landing floor ends. In particular, this is to be understood as the departure time at which the car leaves the holding floor. In particular, at the end of the stop, a closing time to understand, close to which the doors of the car.
- the readjustment from the beginning of the hold stop to the entire stop of holding is carried out until the end of the hold stop and at the end of the hold stop the car is stopped. This version is particularly suitable if the readjustment is necessary during the entire stop.
- a first time is determined at which the readjustment is carried out, and a second time point is determined at which the shut-down of the car is performed.
- This first and second time will depend in particular on the at least one Operating parameters of the elevator system determined. In particular, this determination of the first and second times is performed before the car begins the stop of stopping.
- the first time may be before the second time, on the other hand, conversely, the second time may be before the first. If it is determined that no readjustment is to be performed, no first time is determined. In this case, in particular, only the second time is determined.
- a concrete, fixed, absolute time is not necessarily determined in each case as this first and second time.
- a time frame can also be determined as the first and second time during which the readjustment or shutdown is carried out or during which the start of the readjustment or shutdown is started.
- the first and the second time points can each be selected flexibly and in dependence on the current situation of the elevator system or on the ascertained readjustment requirement.
- the power flow interruption and the shutdown can be performed at the most favorable convenient times.
- a start of the stop is determined as the first time at which the readjustment is performed.
- the start of the stop-stop is determined as the first time when the first load change, the second load change, the first number of passengers and / or the second number of passengers the exceed the respective limit.
- it is monitored from the first time on the basis of the at least one operating parameter and / or on the basis of the further operating parameters when the readjustment is started.
- the second time at which the car is stopped is after the end of the readjustment when the start of the stop is determined as the first time.
- the second time may be immediately after the end of the readjustment.
- a certain time interval can be waited for before the car is shut down.
- an end of the hold stop is determined as the second time when the start of the hold stop is determined as the first time.
- the beginning of the hold stop is determined as the second time.
- the first time in this case is preferably after the end of the power flow interruption.
- the end of the hold stop in this case may be determined as the first time.
- the beginning of the stop is determined in the absence of readjustment requirement as the second time. Lack of readjustment requirement means that it is determined that there is no need for readjustment.
- the determination of the readjustment requirement is carried out as a function of the at least one operating parameter of the elevator system, which is determined by means of a destination selection control of the elevator system.
- the elevator control is aware of how many passengers are leaving the car in the hold floor in the course of the stop and how many are entering the car.
- the first and second number of passgates and, in particular, the first and second load changes can thus be determined in each case as operating parameters. If, for example, the evaluation of the destination selection control information indicates that the first and second numbers each exceed a limit in the stopping floor, ie that comparatively many passengers leave and enter the car, the readjustment is preferably carried out before the car is shut down.
- the readjustment at the beginning of Garstopps and stopping at the end of Garstopps be performed.
- the start of the hold stop is determined in particular as the first time and the end of the hold stop as the second time.
- the car is operated in particular during the entire stop of the stop in the readjustment.
- the evaluation of the destination selection control shows that the first and second numbers do not exceed the possible limit value, ie that comparatively little or no passengers leave or enter the car, it is determined in particular that there is no readjustment requirement. In this case, no readjustment will be carried out.
- the shutdown of the car is performed in this case, preferably at the beginning of the stop.
- the beginning of the stop is in this case preferably determined as the second time.
- the determination of the readjustment requirement is carried out as a function of the at least one operating parameter of the elevator system, which is preferably determined by means of a utilization profile of the elevator system.
- a utilization profile can for example be learned automatically by the elevator system or by the elevator control and / or determined by means of statistical methods.
- the utilization profile can also be predetermined and describe, for example, known scenarios or known peak times.
- Such a utilization profile describes in particular the utilization of the elevator system as a function of specific times, for example as a function of the time of day and / or the day of the week. In particular, the utilization profile describes at what times (both with regard to the times of the day and the day of the week) there are peak times.
- the method according to the invention is always configured permanently on a main retaining floor, for example the lobby, whereby in particular the power flow interruption and / or service brake activation takes place after the readjustment.
- the mentioned utilization profile can be designed to be adaptive, for example it can learn the utilization depending on the time of day, depending on the week or calendar days. Also, corresponding specifications are possible after manual or automatic statistical evaluation. In the simplest case, a manual configuration depending on certain times of the day and / or certain stops of the elevator system can take place.
- the determination of the readjustment requirement is carried out as a function of the at least one operating parameter, which is preferably determined by means of a personal and / or load-specific sensor signal.
- Such a person or load-specific sensor signal is to be understood as meaning a sensor signal which gives information about passengers or loads which are located in the car or in the holding floor.
- a suitable sensor monitors in particular an area in front of the car in the holding floor and / or the interior of the car itself.
- a suitable camera as such a sensor picks up an image signal and / or a video signal as such a personal or load-specific sensor signal.
- an optical or especially an infrared sensor to record an optical or infrared signal
- an ultrasonic sensor to record an ultrasound signal which in each case permits load-related or person-related statements.
- the second load change and / or the second number of passengers by which the load of the car in the stopping floor is increased can be determined.
- a load or cargo can be detected, which should be loaded in the hold floor in the car or the second number of passengers who want to enter the car.
- a sensor is preferably in the form of a load-measuring sensor (for example a load cell or an optical force / spring travel sensor) for measuring the load of the car.
- the load-measuring sensor records a load-measuring signal as such a sensor-specific and / or load-specific sensor signal.
- the at least one operating parameter is preferably determined by means of such a load measurement of the car.
- the current load in the car is determined as the at least one operating parameter.
- Such a load measurement is suitable for example in freight or freight elevators. If the load measurement shows that the car is empty before arriving in the holding floor, this means that a load or cargo is loaded into the car in the stopping floor and thus a second load change will take place. In this case, in particular the beginning of the stop is determined as the first time.
- the load measurement shows that the car is not empty before arriving at the stopping floor, this means that a load or cargo is being transported out of the car in the stopping floor and thus a first load change will take place.
- the beginning of the stop is determined as the first time.
- the energy flow interruption can also be carried out at the beginning of the stop of holding, and the post-regulation can be carried out immediately after the end of the energy flow interruption.
- the power flow interruption is performed during the stop of stopping, it is checked whether the power flow of the car drive is actually interrupted. If this is not the case, a re-start of the car is prevented for safety reasons in accordance with the standard EN 81 in particular.
