Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 11.
  • shading systems, awnings or other devices comparable to them for example roller shutters, roller shutters or the like, have a type of curtain or the awning cover, which is wound on a shaft and can be removed more or less completely from it, if desired .
  • awning In connection with shading systems or awnings, and in the following the term awning is used exclusively, without this being to be understood as being restrictive with regard to other possible applications of the present invention, more automated control systems are also known which, when they are in the automated operating mode are, depending on whether the sun is shining or not, extend the awning, the sunshine exposure can be detected by means of suitable photo sensors or the like.
  • the present invention has for its object to increase the useful life of an awning, even if a wind force is determined that would otherwise lead to the awning being completely retracted, and at the same time ensure that, regardless of the operating mode, the awning control is operated in each case (automatically or manually), the respective wind force action is always given priority, so it is ensured under all circumstances that wind forces acting do not damage the awning or the awning cover.
  • the invention solves this problem with the characterizing features of the main claim and has the advantage that the awning maintains its function as a sun protection system even when a certain speed of wind occurs at the same time, to which the control must necessarily react.
  • the control system decides that the awning is retracted, but only up to a position such that the then correspondingly reduced fabric area can easily absorb the wind load acting on it, so that it remains safely free of damage.
  • a correspondingly partial retracted awning can therefore have a larger, sometimes much greater wind resistance while maintaining its function as a sun protection system.
  • the reaction and the inclusion of the wind data have absolute priority in the entire control mechanism of the awning, i. H.
  • the awning can only be extended as far as is ensured on the basis of stored comparison values or when adjusting basic values that the awning wind resistance can withstand the load.
  • the extending awning then stops automatically at predetermined points, even if the extend command is maintained.
  • This also applies to the fully automatic operating sequence of an awning, that is to say those awnings which, when switched manually into this fully automatic operating mode, automatically extend when the sun exposure lasts for a predetermined period of time. In this case too, the respective wind speed is included in the extension process and the end position of the awning is determined from the wind load that can still be tolerated.
  • Such a quick shutdown has a mechanical memory that stores the position of the winding shaft up to a predetermined number (e.g. 10 revolutions) beyond an actual shutdown point.
  • a limit switch for storing the two middle intermediate positions these can be freely set by the end user.
  • the adjustment of these positions is not critical because, in addition to being freely adjustable, the respective wind speeds to which they relate always vary within a predetermined range, so that it is neither expedient nor necessary to work with more precise values.
  • the awning control unit thus formed is then able to specify four different positions of the awning for the four position sensors available, depending on the correspondingly quantized wind speeds, for example, detected by an anemometer .
  • the basic idea of the present invention is to create intermediate positions in a motor-driven awning or shading system that relate to the prevailing wind speed and thus to ensure that the optimal function as a sun protection system is maintained, while at the same time optimal protection of the awning against acting wind load.
  • a preferred embodiment of the present invention comprises the quantized, that is to say step-by-step, actuating movement of the awning over the entire stroke of the extension movement, so that, as illustrated in more detail in a simplified exemplary embodiment explained below, in addition to the two anyway in the control range of a motor-driven awning integrated limit switches (retracted position - maximum extended position) Intermediate position sensors are provided, which here detect two intermediate positions E2 and E3 in addition to the fully retracted end position E1 and the fully extended end position E4 (FIG. 1).
  • two additional sensors are provided, which, in a simplified embodiment, are designed and switched so that a sensor responsive to the position E2 adjacent to the winding tube then supplies a high, i.e. electrical, signal from 0 to high (high) when it is retracted Position E2 is exceeded; the sensor then maintains the high output signal, the sensor output signal changing from high to 0 when extending position E2 in this extending direction.
  • a sensor responsive to the position E2 adjacent to the winding tube then supplies a high, i.e. electrical, signal from 0 to high (high) when it is retracted Position E2 is exceeded; the sensor then maintains the high output signal, the sensor output signal changing from high to 0 when extending position E2 in this extending direction.
  • the second position sensor then serves to determine the intermediate position E3 located approximately between position E2 and the fully extended end position E4, as indicated in FIG. 1, and is designed such that it changes a high-level output signal to 0 when retracting and in the opposite direction when extending Direction, wherein, as can also be seen from the illustration in FIG. 1, the signal of the intermediate sensor for position E2, which is referred to below as sensor S E2 , is high between positions E1 and E2 and zero value between positions E2 to E4 has, while the sensor S E3 from position E1 to position E3 has a zero value and lies high between E3 and E4.
  • the sensor signals In the first case there are necessarily constant sensor signals which, as shown in FIG. 4, can be discriminated for determining the position of the awning, while in the second case the sensor signals have a jumping behavior when positions E2 or E3 are reached or exceeded, i.e. either go down or go up so that the corresponding drive control signals for the motor can be obtained in this way.
  • the two intermediate sensors can be designed in any way; it is preferably an electromechanical switch that responds to a predetermined number of revolutions of the winding shaft and then changes to its other switching state.
  • FIG. 3 A simplified flowchart which shows the basic control sequence according to the invention in one possible implementation form is shown in Fig. 3; Starting from a wind sensor block, which is explained in more detail below with reference to FIG. 5 and which provides an analog control circuit or a microprocessor, for example four setpoint values for the awning position, which are dependent on the respective wind strength, it is first determined at decision block II that whether the awning control system is in automatic mode or whether manual intervention has taken place or is in progress.
  • decision block III can be used to determine whether there is solar radiation or not. If there is no solar radiation, the awning is retracted via circuit block IV; If the sun is shining, the awning is commanded to move to block V, but taking into account the wind conditions, which have absolute priority. Decision block VI therefore determines whether there is wind or not; if this is the case, the setpoint position x p prescribed by the sensor block I in accordance with the wind conditions is compared with the actual actual value position x ist . If the actual value position is above the desired value position, the control unit determines via circuit block VI that the awning is retracted until decision block VII determines that the actual value position of the awning essentially corresponds to the wind speed desired value position.
  • the loop returns to the input of decision block V and continuously monitors whether the actual position of the awning now taken still corresponds to the wind conditions or whether the position has to be reduced further when the wind is refreshing.
  • a further decision block can follow after completion of a first retracting operation of the awning, which is labeled VIII and determines whether it will soon be possible to extend the awning again when the wind blows decreases or goes towards 0.
  • this decision block VIII is equipped in such a way that an extension command is only issued if the position setpoint given by the current wind speed is one step higher than the actual position of the awning, so that it actually moves to the next higher step, for example from the Can move position E2 to position E3 or from this to position E4.
  • an extension command is issued to the next position level in accordance with block IX and, at the same time, the loop is formed to the input of block IV, which compares the new actual awning position with the new wind-related new awning setpoint position.
  • control system determines at decision block X whether the awning is extended; when it is extended, the circle closes at the entrance to decision block VI.
  • converted position output signals x p , x p-1 selectively reach high potential or it is also possible to have a common output signal to create, which has a different amplitude value depending on the wind speed, with which then continue to work - for example, an output voltage of 0 volts can be generated when there is no wind, 2 volts in weak winds, 4 volts in medium winds and immediately.
  • the actual value of the awning position can be determined in accordance with the representation in FIG. 4, which corresponds approximately to a flow chart; a first decision block XI determines whether the awning is extended at all, which can be determined by one of the limit switches already present; If this limit switch has responded (awning completely retracted), then the awning position is determined according to FIG. 1 to E1 and a corresponding output travel signal can be x o .
  • the sensor signal S E3 is checked; if this is high, for example, then the awning must be between positions E3 and E4; If there is a zero potential at sensor S3, it is then determined whether sensor S2 shows high potential. If this is the case, the awning is between the positions E2 and E3, while if the sensor S2 also shows zero potential, the awning must necessarily be between the positions E2 and E3.
  • This position determination allows a problem-free evaluation of the sensor signals and the creation of the corresponding extend or retract commands by the control unit, the position determination of FIG. 4 starting from a steady state and the Determination also enables any intermediate position of the awning. From the output signals obtained in this way, it is then determined whether these correspond to the respective wind-determined setpoint position signals x p - if there are differences, the awning moves to the next position in each case.
  • the control unit reacts to the signal change, i.e. the edge in the output signals of the intermediate position sensors S E2 or S E3 , and in this case, for example when extending the awning, immediately stops after passing position E2 when the corresponding wind-determined position signal predominantly indicates average wind which only allows an extension to this position.
  • a memory for example an EPROM, for the control decisions, to which the respective operating states, i.e. wind-determined awning setpoints and position-determined actual awning values, and, when switching to automatic operation, a signal as to whether solar radiation is present, are fed to its inputs and which then specifies the output control signals according to its addressed, stored values.
  • a memory for example an EPROM
  • a logic control circuit including a suitable diode matrix coding circuit or a microprocessor with memory (EPROM) or also another logic control circuit which has semiconductor switches 11 connected in series at its two outputs (for extending the awning) or 11 '(for retracting the awning) issues the control commands, which then cause the drive motor to be actuated in one or the other direction of rotation via downstream relay circuits 12 or 12'.
  • the control of the semiconductors 11, 11 ' can take place via light emitting diodes 13, 13', so that the direction of movement is shown on the outside of a display.
  • the sensor Since the entrance movement and the exit movement of the awning each act on the intermediate position sensors S2 and S3 in different ways - the sensor jumps in its output signal either from high to low or vice versa - it can make sense to add memory depending on the entry or exit movement set, each of which maintains one or the other switching state until the respective sensor is "run over" in the opposite direction - this also makes sense if the response of the sensors is only triggered by the awning movement, i.e. tripping takes place, which takes place further The run goes out again.
  • position sensors can be designed in a variety of ways and do not necessarily have to be physical individual switches.
  • a preferred possibility for realizing position sensors could also be, for example, Incremental encoder controlled by the winding shaft speed or simply to provide a counter which, when certain counter readings are reached, emits a signal E1, E2, E3 ... corresponding to the actual position of the awning.
