Description

The invention relates to a method and a device for operating Rolling systems and lifting systems.

Such rolling systems can be used in particular for roller shutters, roller shutters, blinds, Awnings and movie screens should be formed. Generally, such is Roll system driven by a drive, in particular an electric motor, which causes the rolling system to move upwards depending on the control or makes a downward move. With an awning is the downward movement as an outward movement and the upward movement as an inward movement educated. In the case of roller shutters and roller shutters, this means an upward movement opening a window, gate or the like while using the Downward movement a closing operation is carried out.

Lifting systems of this type are generally systems with linearly guided actuators, which, for example, have linear motors as drives. This Systems perform lifting movements, which are generally linear Movements are to be understood. An example of such a lifting system is a tilt gate.

Known systems of this type are controlled without contact, in particular Radio systems used to control the rolling systems or lifting systems become. Such radio systems include transceiver units with one transmitter integrated in a handheld device and a respective drive Rolling system or lifting system assigned receiver.

The transmitter sends transmission signals by operating buttons on the handheld device to the receiver, causing the movement of the rolling system or lifting system is controllable.

In the case of a multiple arrangement of rolling systems or lifting systems, the individual rolling systems or lifting systems controlled by separate transmitters, whereby a receiver is preferably assigned to each transmitter.

One difficulty with such arrangements is to find an appropriate one Define the assignment of the transmitter to the individual receiver. typically, Such an assignment can take place in a learning phase in which an identification number from a transmitter into the assigned receiver or the like is entered, on the basis of which the transmitter can be identified.

This procedure is not problematic as long as only one pair of transmitters and receivers exists because then the assignment of the receiver to the transmitter to be taught is clear. In the event that multiple rolling systems or lifting systems are provided, which are controlled with separate transmitter-receiver pairs, such a clear assignment is only given if the Power supply for the rolling systems or lifting systems can be switched on and off individually are. Only then can a clear assignment be made during the learning phase a transmitter to a receiver can be manufactured if only the rolling system or lifting system with the receiver to be read in a power supply is connected, all other rolling systems or lifting systems are switched off by switching off their power supply. In In practice, however, this configuration can only be implemented in the rarest of cases, since all rolling systems are connected to a common power supply are.

A system of roller doors and the like is known from EP 0 867 848 B1, which are controlled without contact by means of transmitter-receiver pairs, in which the respective transmitter sends radio signals to a roller shutter Recipient sends. So that the sender only the assigned receiver control, an identification number must be provided in this in a single phase be stored, which serves to identify the assigned transmitter. This requires the use of a second transmitter, by means of which one Test identification number is read into the receiver to be parameterized becomes. This test identification number must be in the receiver as a parameter value be deposited. As soon as the recipient receives the test identification number, it is put into a learning mode, in which this of the assigned transmitter whose identification number is read.

The disadvantage of this method is, on the one hand, that for carrying out the Teach-in process in which a receiver is on a particular transmitter is taught, an additional transmitter is required.

This leads to an undesirably high level of operating effort during implementation of the learning process.

Another disadvantage is that the test identification number of the additional Transmitter must first be taught in the receiver. This sets you up further teach-in process ahead, which also includes suitable controls must be provided on the recipient side. These controls lead to increased design effort on the receiving side.

The invention has for its object a method and a device of the type mentioned in the introduction to make commissioning as simple as possible for a contactlessly controlled arrangement of rolling systems and lifting systems.

The features of claims 2 and 15 are provided to achieve this object. Advantageous embodiments and expedient developments of the Invention are described in the subclaims.

The invention relates to an arrangement of rolling systems or lifting systems, each rolling system or lifting system being controlled by means of a transmitter is in which this transmission signals in a the drive of the respective rolling system or recipients assigned to the lifting system. By issuing a The start signal using a transmitter becomes the receiver of the rolling systems or lifting systems in a learning mode in which the rolling systems or lifting systems independently of each other a cyclic reference movement To run. The recipient of a rolling system or lifting system is assigned to the transmitter if it is within a specified time window within a cycle of the reference movement one sent by the transmitter Activation signal received.

The invention can be used in the same way for rolling systems and lifting systems. In the following, the invention is used solely for the use of rolling systems explained, these statements in the same way for lifting systems are.

The basic idea of the invention is that the assignment of a transmitter to one of the recipients of the individual rolling systems on the basis of the Rolling systems carried out reference movements, which by the Sending the start signal of the transmitter to be taught in to the individual Rolling system receivers are triggered. It is essential that the cyclical reference movements are the same for all rolling systems, however, these are carried out independently of one another, in particular being out of phase to each other.

For example, one cycle of a reference movement is an upward movement and a downward movement of a rolling system, each are separated by a break. Here is the duration of an upward movement preferably identical to the duration of the subsequent downward movement. There for Execution of these reference movements of the rolling systems separate drives and control units are provided in the individual rolling systems the reference movements due to the always existing tolerances in these components executed with time-varying phase offsets.

For the cycle mentioned as an example, this means that if a rolling system a next upward movement starts from its lower end point, the other roller systems, for example, stand still or are currently in one Downward movement.

The assignment of the transmitter to be taught to a given receiver takes place in that this receiver from the transmitter within a predetermined Time window receives the activation signal.

It is crucial here that this time window for the operator operating the transmitter Operator can be identified on the basis of the reference movement known to them.

For the cycle mentioned as an example, the time window can just start an upward movement of a rolling system in the computer unit of this rolling system be opened.

The operator then only needs the individual's reference movements Track rolling systems. As soon as the rolling system to be selected by him its upward movement within a cycle of the reference movement starts, the operator triggers one using a control button Handheld device in which the transmitter is integrated, the transmission of the activation signal out.

As is guaranteed by the asynchronous reference movements, that the time window is only open for the selected rolling system, that is Activation signal only integrated in the computer unit of this rolling system and stored, thereby assigning the transmitter to the receiver, the is assigned to this computing unit.

The activation signal preferably contains the respective transmitter identifying identification number. Through this identification number is given a clear assignment of the transmitter to the respective recipient.

In a particularly advantageous development of the invention, the following is described on the activation signal a second activation signal from the transmitter in the Receiver fed. The second activation signal is advantageously received analogous to the first activation signal within a time window. The time window can then be opened for the cycle mentioned as an example when a rolling system is just initiating a downward movement.

In contrast to the first activation signal, the second activation signal serves for setting operating parameters of the rolling system. For example can by means of the second activation signal by controlling the drive the direction of movement of the rolling system can be specified. This ensures in particular that in the contactless control of the Roll systems using a handheld device in which the respective transmitter is integrated is when pressing an operating button on the handheld device for the up or Downward movement is actually the corresponding movement of the rolling system is initiated.

The rolling system particularly advantageously interrupts its reference movement, as soon as the activation signal in its computer unit within the time window has been imported. As a result, the operator can immediately see that the learning process has been successfully completed.

The teach-in mode, which is triggered by the start signal of the transmitter to be taught-in extends over a preferably fixed time interval, this being particularly advantageous for several cycles of reference movements includes. This relatively long period of time ensures that within the learning mode due to the component tolerances of the components of the Roll systems whose reference movements to each other are sufficient have a large phase shift so that it is guaranteed that at a time within the teach-in mode, only the time window for one rolling system is opened in the assigned computer unit. This ensures that the activation signal sent by the transmitter only in the computer unit a rolling system is registered.

By repeating the learning phase with different transmitters these one after the other to the recipients of the desired roll systems be assigned.

A major advantage of the method according to the invention is that none for teaching a transmitter to a receiver of a rolling system mechanical or electrical connection means are necessary. The learning process can rather be completely contactless via the teach-in transmitter to be controlled. With the method according to the invention an error-free and simple assignment of a transmitter to a freely selectable one Recipient feasible.

FIG. 1 shows an arrangement of contactlessly controlled rolling systems. in the In the present case, three roller doors 1 are provided as roller systems. in principle any number of rolling systems can be provided, these as Roller shutters, shutters, blinds, awnings, film screens and the like are formed could be.

Each roller door 1 is driven by a drive 2, which is connected to a common, not shown power supply is connected. Conveniently, the drives 2 are each formed by an electric motor.

The roller doors 1 can perform an upward and downward movement, whereby a gate is closed or opened by means of a roller door 1 can.

A computer unit 3 is assigned to each drive 2. The computing unit 3 is Part of a control unit 4, which controls the movement of a roller shutter 1 serves. The computer unit 3 has a microprocessor, not shown and a storage unit, also not shown.

The control commands for controlling a roller shutter 1 are carried out by means of a transceiver generated. This has a transmitter 5 and one to the respective Computer unit 3 connected receiver 6. The transmitter 5 transmits Broadcast signals 7 generally in the form of electromagnetic waves to the assigned receiver 6. In the assigned computer unit 3, the received transmission signals 7 for controlling the movement of the associated Rolling gates 1 evaluated. The transmitter sends 5 radio signals particularly advantageously to the assigned receiver 6.

As can be seen from FIG. 1, each transmitter 5 is integrated in a hand-held device 8. The handheld device 8 has several operating buttons 9a-9d. The ones with "up" and "Ab" marked control buttons 9a, 9b are used to trigger an upward or a downward movement of the roller shutter 1. With the one marked "Stop" Operating button 9c, the roller shutter 1 can be stopped. With "Teach" designated control button 9d is used to initiate a teach-in process.

A transmitter 5 is assigned to a receiver 6 on the basis of a Coding, in particular an identification number, which is in the transmitter 5 and in Receiver 6 is deposited. In the present case it is the identification number for a receiver 6 in the memory unit of the connected computer unit 3 deposited.

The assignment of the identification number of a transmitter 5 to the respective one Receiver 6 takes place during the learning process. Teaching the transmitter 5 on a receiver 6 is controlled via the transmitter 5 itself without contact.

The learning process is started by an operator in that the control button 9d marked "Teach" on the handheld device 8, in which the transmitter 5 is integrated, presses. As a result, the transmitter 5 sends a start signal from which is received by all receivers 6. By receiving the Start signal change the roller doors 1 assigned to the receivers 6 into one Learning mode. In this, the roller doors 1 lead during a predetermined A cyclical reference movement.

The reference movement is of the same design for all roller doors 1. The Cycles of the reference movements of the roller doors 1 are shown schematically in FIG. 3 shown.

A cycle comprises an upward and a downward movement of the roller shutter 1, the upward movement of a roller shutter 1 being denoted by +1 in FIG. 3 and a downward movement being denoted by -1. There is a pause between the upward and downward movement, during which the roller shutter 1 stands still. This is designated 0 in the diagrams in FIG. The duration Δt _{1 of} an upward movement within a cycle corresponds to the duration Δt _{1 of} a downward movement. The time interval Δt ₁ is preferably of the order of 1 sec. The duration of a pause is Δt ₂ and is of the same order of magnitude.

The total duration of the learning phase is chosen so that it spans several cycles includes. The duration of the learning phase is preferably about 30 seconds.

Since the reference movements of the roller shutters 1 are carried out independently of one another and because the components used for this, especially the respective Control unit 4 and the respective drive 2 significant due to the system Construction tolerances are the movements of the individual cycles Reference movements are not completely identical. As a result, the reference movements run of the individual roller doors 1 with time-varying phase offsets from, which are shown in Figure 3.

This can easily be observed by the operator because the individual roller shutters 1 at a time due to the phase offsets different positions and movements.

As the duration of the learning phase progresses, these phase offsets increase more pronounced.

To reinforce this effect, the specification of the reference movements of the Rolling gates 1 via the control unit 4 through different parameter assignments already done slightly differently.

A time window of predetermined duration is opened in each computer unit 3 at a predetermined point in time within a cycle of the reference movement. The time windows are labeled F ₁ , F ₂ , F _{3 in} FIG. ₃ , the time durations of which are preferably identical. In the present case, a time window F ₁ , F ₂ or F ₃ is opened just when the roller shutter 1 starts its upward movement. The duration of a time window is considerably shorter than the time interval Δt _{1 of} the upward movement of the roller shutter 1.

As can be seen from Figure 3, the choice of the sizes of the time windows as well through the phase offsets of the reference movements of the individual roller doors 1 ensures that only one time window for a roller shutter 1 at a time, but not two time windows are open at the same time.

The positions of the time windows are known to the operator and based on the Observation of the reference movements of the roller doors 1 can be identified in a simple manner. In the present case, the operator knows that the time window is open for a roller shutter 1 if it stops after a pause starts with the upward movement.

Based on this, the operator takes the assignment of what is to be taught in by him Receiver 6 of a particular roller shutter 1 before.

To do this, the operator presses the control button 9a labeled "Open", as soon as the operator recognizes that the roller door 1 with the one to be selected Receiver 6 is just beginning the upward movement. By pressing this control button 9a, the transmitter 5 sends out an activation signal. The activation signal preferably contains the identification number. In principle, the Identification number also sent after the activation signal become.

The activation signal is sent from the transmitter 5 to all receivers 6. however the activation signal is only in the computer unit 3 of the roller shutter 1 evaluated for which the time window is currently open. In the others Computer units 3, the activation signal is discarded.

Since the time window is only open in the computer unit 3 that the rolling gate 1 controls which is currently starting the upward movement, is alone in this Computer unit 3 received the activation signal and evaluated, wherein in particular the identification number transmitted with the activation signal of the transmitter 5 is stored in the memory unit of the computer unit 3 becomes. This means that the transmitter 5 is assigned to the relevant receiver 6 performed.

To avoid timing problems when recording the activation signal within the time window is preferred in the computer unit 3 an edge evaluation was carried out. For this purpose, it is checked whether the rising Edge of the activation signal lies within the respective time window.

As soon as the activation signal in a computer unit 3 within a time window has been registered and by reading the identification number the assignment of the respective receiver 6 to the transmitter 5 to be taught has taken place, the roller door 1 assigned to this computer unit 3 is stopped. In this way, the operator can easily determine that the learning process has been successfully completed.
