Description

The invention relates to a control unit for domestic installation for the wired remote control of a drive device for a darkening device or security device with the features of the preamble of claim 1, a drive arrangement for a darkening device or security device with the features of the preamble of claim 7, a method for wired remote control a driving device for a dimming device with the features of the preamble of claim 9 and a computer program with program code for carrying out the method according to claim 15.

The drive device in question can be used for a large number of dimming devices or the like. It is only essential that a movable closure element is present. Examples include roller shutters, blinds, awnings, but also safety devices such as gates and curtains, and in particular roller shutters and roller blinds. The following is the scope of the roller shutters in the foreground, but this is not to be understood as limiting.

From the prior art, a drive arrangement for a roller shutter is known in which a tubular motor is remotely controlled by a control unit wired. The tubular motor can in this case correspond to a variety of possible designs. All tubular motors in question here have in common that they are capacitor motors according to the drive principle. Capacitor motors are electric motors and work on the principle of the asynchronous motor, so have a squirrel cage rotor, which moves in a rotating field generated by a stator. In contrast to conventional asynchronous motors, however, the capacitor motor runs with single-phase alternating current.

The required additional phase is generated as follows: The first of two stator windings, the so-called main winding, is directly connected to the existing AC phase by the regularly external control unit. This main winding is connected via a so-called operating capacitor to the second stator winding, the so-called auxiliary winding. Through this Operating capacitor is formed on the auxiliary winding a phase-shifted voltage to the main winding AC voltage, which in turn creates the desired magnetic field in the induction motor.

A specific assignment of the AC phase to a stator winding as a main winding causes a rotational movement of the capacitor motor in a certain direction. Instead, to achieve movement of the capacitor motor in the opposite direction, the former auxiliary winding may instead be directly connected to the AC phase by the controller, thereby becoming the main winding. Also, because a simultaneous application of both stator windings is detrimental to the induction motor, the control unit in turn switches such that no direct loading of the former main winding takes place with the AC phase. Rather, a phase-shifted auxiliary phase is generated at this analog over the operating capacitor. The conversion of the direction reversal by a change made by the control unit of the directly connected to AC voltage stator winding is common to all capacitor motors relevant here.

Notwithstanding this common basic principle, however, there is a wide variety of tubular engine designs. Basically, the type of mechanical and electronic tubular motors are to be distinguished. In the mechanical tubular motors, the two phase terminals are regularly connected directly to the main and auxiliary windings, which is why a simultaneous connection of the two phase terminals to the alternating current phase must be necessarily prevented by the control unit. Electronic tubular motors have their own internal control electronics which, depending on the voltage at the phase terminals, generally only connect at most one phase terminal to the associated winding via an internal relay in each case. The electronic tubular motors in turn differ, depending on the manufacturer and model, both by their internal structure and by the breadth of the range of functions. So there are tubular motors whose control electronics allow an electronic programming of the end point setting. Other tubular motors do not provide these or similar functionality. These additional functionalities are addressed regularly via the control unit, which is usually installed spatially separated from the tubular motor and the Users should provide a central interface for the control and adjustment of the motor for the roller shutter.

A disadvantage of the control devices known from the prior art that although virtually any control unit can control each tubular motor in his direction by the same applicable to all tubular motors type of directional control, but for the control unit is not always recognizable whether the currently installed tubular motor supports some advanced functionality, such as the electronic endpoint setting. The control unit must then display such a possibility in its user interface, for example in a menu, with the risk that the tubular motor does not provide for this at all. In a user confronted with such a menu item and simultaneous inefficiency, the impression can arise that there is a defect either in the control unit or in the tubular motor or even in both devices.

The problem underlying the invention is thus a control device for domestic installation for the wired remote control of a drive device for a darkening device or security device, a drive assembly with such a control device, a method for wired remote control of a drive device for a darkening device or security device and a computer program for Implementation of such a method in such a way and further develop that a certain type of drive device can be identified via the existing possibilities of wired remote control.

The above problem is solved in a control device according to the preamble of claim 1 by the features of the characterizing part of claim 1, in a drive arrangement according to the preamble of claim 7 by the features of the characterizing part of claim 7, in a method for wired remote control of a drive device according to the preamble of claim 9 by the features of the characterizing part of claim 9 and in a computer program by a computer program having the features of claim 15.

It is essential to recognize that in certain electronic drive devices with capacitor motor and especially in tubular motors, the respective Auxiliary winding, which is not connected at the specific moment with the AC phase, can be used to identify the type and type of about the tubular motor. Thus, the phase terminals are not only connected to the windings of the actual capacitor motor, but also depending on the type with a rectifier circuit or other comparable circuit which provides the necessary supply voltage for the electronics of the tubular motor. Depending on the type of this circuit for generating the supply voltage follows from this also a different, detectable voltage behavior at the respective auxiliary winding associated phase terminal. Since both phase terminals are always electrically connected to the control unit, the control unit can thus detect the type, the manufacturer or the type of installed drive device by measuring the phase terminal not connected to the AC phase and, on this basis, the range of functions supported by this drive device unlock its user interface.

According to the proposal, the control unit therefore detects the voltage profile at the other phase terminal during the application of the phase terminal associated with the respective adjustment direction with the alternating current phase. By comparing the detected voltage curve, the controller can then determine the type, the manufacturer or even the exact type designation of the drive device and adjust both the control of the drive device as well as the representation of the user interface to the user.

The particularly preferred embodiments of the control device according to claims 3 and 4 and the method according to claims 11 and 12 are aimed at detecting an electronic tube motor with a bridge rectifier circuit. In such electronic tubular motors, the supply voltage necessary for the control electronics is provided by a bridge rectifier with smoothing capacitor. So that the bridge rectifier functions independently of the assignment of the alternating current phase to the two phase terminals, these are regularly brought together via a respective capacitor to the input of the bridge rectifier. However, this also means that a voltage characteristic that is typical for the bridge rectifier can be detected at the phase terminal that is not being acted upon by the alternating voltage phase.

The also particularly preferred embodiments of the control device according to claims 5 and 6 and the method according to claims 13 and 14 provide particularly suitable reactions to the detection of a particular type of tubular engine. For example, an electronic endpoint setting can be enabled and thus offered to the user in the user interface, for example as a menu item. Likewise, such an adjustment process can be started in the control unit, which would not or at least not produce the desired effect in another tubular motor type. Thus, known from the prior art ways for unlocking such adjustment options can be omitted, such as mechanically by means of a Ausbrechbrücke.

Particularly helpful is a proposed control unit in a drive assembly according to claim 8, wherein the controller is located outside the housing of the drive device and is connected only by a cable with the phase terminals with this. In such a case, the possibilities of otherwise establishing contact with the drive device are particularly limited.

In the following the invention will be explained in more detail with reference to a drawing showing only one exemplary embodiment. In the drawing shows:

one at a phase terminal, which is not connected to the AC phase, detected voltage signal which substantially corresponds to a predetermined voltage waveform in the form of a square wave voltage.

The proposed solution is in the drawing based on a control unit 1 for domestic installation for the wired remote control of a Antriebsvortung the upward movement of the shutter and the other possible adjustment accordingly the downward movement of the shutter.

The drive phase terminal 14 is that of the two phase terminals 14, 15 of the drive device 2, the application of which leads to the AC phase to a movement of the capacitor motor 5 in the desired adjustment direction. The antiphase terminal 15 is the other phase terminal.

The switching unit 16 is moreover configured to separate the outer conductor 11 from the antiphase terminal 15 of the two phase terminals 14, 15 assigned to an opposite direction of the adjustment direction.

In the tubular motor 2 shown here, the AC voltage now applied to the drive phase terminal 14 causes the first directional relay 17 to be closed and the second directional relay 18 to be opened. Thus, the main phase is applied to the first stator 7 and through the operating capacitor 5, the auxiliary phase is formed on the second stator winding 8. The third stator winding 9 in turn is connected to the neutral conductor 12.

The control unit 1 also comprises an evaluation unit 19, which is connected to both phase terminals 14, 15 regardless of the switching position of the switching unit 16 and is adapted to detect a voltage signal at the antiphase terminal 15 during the switching of the outer conductor 11 to the drive phase terminal 14. The detected voltage signal can be any type and in particular have any shape and length. The detected voltage signal may also represent only the filtered DC voltage value of the voltage applied to the antiphase terminal 15 or any other filtering of this voltage. The measurement of the voltage takes place relative to the neutral conductor 12.

Finally, the evaluation unit 19 is configured to detect a type of the drive device 2 from a predetermined set of possible designs based on the detected voltage signal. The type of construction may be the fundamental distinction between a mechanical and an electronic drive device, and specifically the distinction between a mechanical and an electronic tubular motor.

In a mechanical tubular motor, the main and auxiliary phases are often connected directly to the phase terminals. In an electronic tubular motor, however, in addition to a control electronics 31 regularly directional relay available, which selectively and alternately main and auxiliary phase connect to the terminals. Furthermore, the end point adjustment in mechanical tubular motors is often done by mechanical intervention, such as by adjusting a screw, whereas in electronic tubular motors, the end point adjustment can be done electronically.

However, the design can also indicate the presence or absence of individual further components in the drive device 2 or specific circuitry implementations of certain functionalities, such as the DC voltage supply. Finally, the specification of the type may also identify the manufacturer of the drive device 2 or determine the specific type of drive device of a manufacturer. In particular, the evaluation unit 19 may be configured to generate a signal indicating a type of the drive device 2 from a predetermined set of possible designs. This signal may be analog or digital and of any complexity and either in any form externally communicated by the controller 1 or used only within the controller 1.

It is particularly preferred that the predetermined quantity of possible designs comprises a tubular-motor electronic type, and in particular a tubular-motor electronic type with a bridge rectifier circuit 20. A bridge rectifier circuit 20 connected to the phase terminals 14, 15 shows a particularly clearly recognizable voltage behavior at the antiphase terminal 15.

According to a further particularly preferred embodiment, the evaluation unit 19 is configured to recognize a tubular electronic motor type and especially a tubular motor electronic type with bridge rectifier circuit 20 in the case of a detected voltage signal which corresponds to a predetermined voltage criterion. The predetermined voltage criterion characterizes the known voltage behavior of the associated electronic tubular motor design at the antiphase terminal 15, and may include any condition formulating the voltage waveform, either as a snapshot or over a longer detection period. Preferably, the evaluation unit 19 generates a signal indicative of a tubular motor electronic type, and more particularly, a tubular motor electronic type having a bridge rectifier circuit 20.

It is preferred that the predetermined voltage criterion comprises exceeding a predetermined minimum voltage level and falling below a predetermined maximum voltage level, either in combination or alternatively. In other words, the voltage criterion is met if the detected voltage signal either falls below a predetermined minimum voltage level and the voltage signal simultaneously or alternatively exceeds a predetermined maximum voltage level.

A voltage curve which is particularly suitable for the determination of an electronic tube motor type with bridge rectifier circuit essentially represents a square-wave voltage 21 with a predetermined amplitude and a frequency which corresponds to the frequency of the AC voltage on the outer conductor 11. Such a rectangular voltage 21 is in the Fig. 3 shown. In this case, the period 22 of the square-wave voltage 21 is identical to the period of the AC voltage on the outer conductor 11.

It is important that the voltage signal detected by the evaluation unit 19 does not have to correspond to such a square-wave voltage 21 in the sense of an identity, but also and in particular can correspond to the filtering of such a square-wave voltage 21. In this case, in particular, a high-pass filtering of such a rectangular voltage 21 comes into question.

It is further preferred that the evaluation unit 19 is adapted to transmit an electrical signal for electronic end point adjustment to the drive device 2 upon detection of a tubular motor electronic type, in particular when recognizing a tubular motor electronic type with bridge rectifier circuit 20. This signal can be transmitted to the drive device 2 in any way and in particular via the phase clamps 14, 15 become. It may be any signal which causes an end point adjustment in the drive device 2.

An equally preferred further embodiment provides that the evaluation unit 19 is adapted to receive a user input to the electronic endpoint setting upon detection of a tubular motor electronic type, in particular when recognizing a tubular motor electronic engine with bridge rectifier circuit 20. This user input can be used in particular as the basis for the generation of the electrical signal just described for transmission to the drive device 2 for the electronic endpoint adjustment.

Fig. 1 next to a proposed drive arrangement for a darkening device or safety device with the tubular motor 2, which is a drive device and a motor housing 23 which encloses it. The tubular motor 2 includes, as already described, the capacitor motor 5 with the two phase terminals 14, 15 and a rectifier circuit, here a bridge rectifier circuit 20, comprising a four-diode bridge rectifier 24 and a parallel circuit of a smoothing capacitor 25 and a voltage limiter 26, here a zener diode, at an output node 27 of the bridge rectifier 24. This parallel connection connects the output node 27 to the ground potential, which also corresponds to the potential of the other output node of the bridge rectifier 24.

The two phase terminals 14, 15 are each connected via a capacitor 28, 29 to an AC voltage input 30 of the bridge rectifier 24, wherein the other input node of the bridge rectifier 24 is connected to the neutral conductor 12.

The drive assembly further comprises a control electronics 31. In addition to various other functions, the control electronics 31 controls, for example, the switching behavior of the directional relay 17, 18. The output node 27 of the bridge rectifier 24 is connected to a supply voltage input of the control electronics 31. In this way, the control electronics 31 is supplied with a DC voltage for operation. In the in the FIG. 1 In the embodiment shown, the DC voltage at the output node 27 of the bridge rectifier 24 has an amount of 24 volts.

That in the Fig. 1 shown control unit 1 is a proposed control unit 1, and is connected in the drive arrangement shown with the two phase terminals 14, 15.

On the basis of in the Fig. 1 The drive arrangement shown will now be exemplified as the controller 1 performs the proposed recognition. Upon user input, the controller 1 is to cause a downward movement of the tube motor 2. The downward movement is effected by applying the main phase to the first stator winding 7 and the resulting auxiliary phase to the second stator winding 8.

Accordingly, the switching unit 16 switches for this purpose so that the outer conductor 11 is connected to the first phase terminal 14. Because then the first directional relay 17 closes, thus a connection between the outer conductor 11 and the first stator winding 7 is produced. Even before closing the first directional relay 17, the second directional relay 18 has been closed. At the second stator winding 8, the auxiliary phase is formed by means of the operating capacitor 6.

The provided by the outer conductor 11 AC voltage at the first phase terminal 14 passes, filtered by the capacitor 28, to the AC voltage input 30 of the bridge rectifier 24. Because the circuit of the bridge rectifier 24 with the capacitors 28, 29 symmetrically to the first phase terminal 14 and the second Phase terminal 15, the operation of the bridge rectifier circuit 20 is also the same, regardless of whether the first phase terminal 14 or the second phase terminal 15 is applied to the AC voltage of the outer conductor 11.

Through the bridge rectifier 24, a rectified voltage would basically arise at the output node 27 of the bridge rectifier 24, which is additionally limited by the blocking voltage of the zener diode 26, in this case to a value of 24 volts, and smoothed by the smoothing capacitor 25. The result is a DC voltage of 24 Volts to ground at the output node 27 of the bridge rectifier 27, which provides the rectifier circuit 20 as a supply voltage, for example, the control electronics 31 available.

Although the voltage at the AC voltage input 30 of the bridge rectifier 24 is caused by the voltage at the first phase terminal 14, as has been recognized according to the invention, the voltage profile at the second phase terminal 15, which is also connected to the AC voltage input 30 via a capacitor 29, determined substantially by the structure of the rectifier circuit 20 and described as follows:

It has already been established that in the steady state a DC voltage of 24 volts to ground is present at the output node 27 of the bridge rectifier 24. During the positive half-cycle of the 220 volt amplitude AC voltage at the first phase terminal 14, the voltage at the AC input 30 through the bridge rectifier 24 - specifically the diode between the AC input 30 and output node 27 - and the Zener diode 26 is limited to a value which is significant the reverse voltage of the zener diode 26, here 24 volts, plus the forward voltage of said diode corresponds.

Conversely, during the negative half cycle of the same AC voltage at the first phase terminal 14, the voltage at the AC input is limited by the diode of the bridge rectifier 24 between the ground and the AC input 30 to a value which substantially corresponds to the ground potential minus the forward voltage of this diode.

With further consideration of the DC decoupling by the capacitor 29 is thus formed on the second phase terminal 15 substantially a square wave voltage without DC component, depending on the dimensions optionally further high-pass filtered by the capacitor 29, with an amplitude which half of the blocking voltage of the Zener diode 26, so here 12 volts , plus the forward voltage of a diode of the bridge rectifier 24. Such a voltage profile at the respective phase terminal 15 which is not connected to the outer conductor 11 is therefore characteristic of this tubular motor 2. Consequently, in a preferred embodiment of the proposed embodiment Control unit 1, the predetermined voltage waveform of a square wave voltage having an amplitude substantially equal to half the reverse voltage of the Zener diode 26, here 12 volts, plus a diode forward voltage and a frequency corresponding to the frequency of the AC voltage on the outer conductor 11, in particular a frequency of 50 hertz.

Upon detection of such a voltage curve by the evaluation unit 19, this can thus recognize this special tubular motor 2 and in response to the user, for example by displaying a corresponding menu item on the screen 3, allow the input of a desired Endpunkteinstellung, which is then communicated to the tubular motor 2. Conversely, the presentation of this menu item can be omitted upon detection of a deviating from the described curve voltage, as well as the attempt of the electronic endpoint adjustment.

In a particularly preferred embodiment of the proposed drive arrangement, in any case, the two phase terminals 14, 15 are connected to the control unit 1 via a cable 32 routed out of the motor housing 23. In addition to the connection through the two phase terminals 14, 15 further electrical connections between the control unit 1 and the drive device 2 may exist. The cable 32 must be led out of the motor housing 23 only in the sense that it is at least partially outside the motor housing 23. Consequently, in this preferred embodiment, a spatial separation between the control unit 1 and the drive device 2 is provided. Precisely because the proposed recognition of the type of drive device 2 also works with such a spatial separation and requires only the already necessary wired connection, it is particularly advantageous in such a scenario.

In a particularly preferred embodiment, the evaluation unit 19 is additionally configured to detect a torque value for the torque output by the capacitor motor 5 and to run through a collision routine when a predetermined behavior of the torque value deviates. In this case, the evaluation unit 19 preferably derives the torque value from the voltage levels at the main and auxiliary phases, so that the hardware of the evaluation unit 19, which is present anyway, can be used for this purpose. The above described double use of the evaluation unit 19, in particular their hardware for the determination of voltage levels, leads to a particularly cost-effective solution. With regard to a possible implementation of the torque detection and the collision routine may refer to the German patent application DE 10 2010 012 181 referenced by the applicant, the content of which is the subject of the present application.

According to a further teaching of the invention, a method for wired remote control of a drive device, in particular a tubular motor, comprising a capacitor motor with two phase terminals for a darkening device or safety device is proposed. It comprises the steps of switching through an external conductor of an AC voltage source to the drive phase terminal of the two phase terminals assigned to an adjustment direction, separating the external conductor from the antiphase terminal of the two phase terminals assigned to an adjustment direction of the adjustment direction. The method is characterized by comprising the further steps of detecting a voltage signal at the antiphase terminal while switching the outer conductor to the drive phase terminal and detecting a type of drive device from a predetermined set of possible designs based on the detected voltage signal, preferably the predetermined one Quantity of possible designs a mechanical Rohrmotorbauart and a tubular motor electronic type, in particular with bridge rectifier circuit includes.

In a preferred embodiment of the method, it comprises the further step of generating a signal indicating the recognized type of drive device.

In a further preferred embodiment of the method, the recognition of a type of condenser motor comprises recognizing an electronic tube motor type, in particular with a bridge rectifier circuit, if the detected voltage signal corresponds to a predetermined voltage criterion, preferably corresponds to a predetermined voltage profile.

Yet another preferred embodiment of the method provides that the predetermined voltage criterion comprises falling below a predetermined minimum level and / or exceeding a predetermined maximum voltage level, preferably the predetermined voltage curve substantially corresponds to a square-wave voltage with a predetermined amplitude and a frequency of the voltage on the outer conductor.

An additional preferred embodiment of the method comprises the further step of transmitting an electrical signal to the electronic end point adjustment drive device upon detection of a tubular motor electronic type, preferably with a bridge rectifier circuit.

A further preferred embodiment of the method comprises, as a further step, the receipt of a user input for the electronic end point adjustment upon detection of a tubular motor electronic type, preferably with a bridge rectifier circuit.

According to yet another teaching of the invention, a computer program is proposed with program code for performing all method steps of the proposed method, when the computer program is executed in a computer. A computer in this sense is equally understood to mean a microcontroller or a similar processor system. Accordingly, the programmer program may also be provided for execution from a microcontroller or other processor.
