Definitions

• the invention relates to a method and a system for reading, monitoring and / or controlling the sequence of movements of a door leaf which is movable by motor, in particular driven by an electric motor, between its closed and open positions, preferably a one-piece or removable movable door leaf a plurality of panels of door leaf which are articulated to one another, the motor drive unit of which can be operated in a controlled manner in at least two different speeds or torque ranges and has an incremental encoder which inputs a series of pulses which represent the movement distance into a storage and counting device which, depending on the Pulse number and thus the distance of the door leaf controls its movement.
• motorized door leaves - this can be one or more pieces, in particular door leaves that can be moved overhead, for example also overhead link, roller and lifting gates - switching devices are provided that are in place and Place the retraction of the door leaf into the respective end position - closed or open position - display and corresponding signals to the control device for the door drive submit.
• the drive is directly influenced by the door leaf position itself, which has proven itself.
• path simulators i.e. devices which map the movement distance of the door leaf in a small space, for which purpose signals, which are dependent on the door leaf position or the drive control, are used reproduce the highly translated path in relation to the door leaf movement in the sense of a reduction, for example in the form of a worm gear.
• this object is achieved in that the door leaf, after it has been attached at the place of use, is driven with a low kinetic energy from any starting position in the direction of one of the end positions - closed or open position , whereupon the storage and counting device recognizes and marks it as one of the end positions when starting into this end position by a mechanical stop and the resulting change in the drive parameters, whereupon the door leaf is operated in the opposite direction of movement again with the low kinetic energy in the opposite end position is moved, namely counting the movement distance pulses emitted by the incremental encoder, until after this opposite end position has been reached, the changes in the drive parameters of the storage and counting device occur again by mechanical stop is recognized and stored as a mark of this other end division, whereupon the intended operating cycle of the door leaf movement is evaluated by evaluating the end position markings and the stored pulses describing the movement distance between the end positions with respect to the movement sequence of the door leaf in such a way that the door leaf between the end positions or at least before
• a system for carrying out the method is characterized by a memory, counting and control device with a memory input for receiving the incremental encoder of the drive unit for the gate. leaf in dependence on the movement distance, with a monitoring device which records the values of the energy supply of the drive unit and with a control device which determines the movement sequence of the door leaf as a function of the stored distance impulses.
• the actual final state assumed in each case by mechanical limitation of the movement sequence of the door leaf in the open position and / or the closed position of the door leaf is recorded and used for the subsequent control of the operating sequence of the door leaf movement.
• the prerequisite for this is the use of a drive unit, the motor - in particular electric motor - of which can be operated in at least two stages, in which relatively different energies are applied to the door leaf or by the door leaf to the mechanical stop approached in the respective end position
• pole-changing motors can be used, one can work with phase control or, in a particularly preferred manner, with a direct current motor, the speed control of which is known.
• the drive unit is provided with an incremental encoder, that is to say a device which emits pulses as a function of the rotational movement of a shaft of this unit, so that the number of pulses reflects the movement distance of the door leaf between the end positions. Delays are noticeable through larger time intervals in the pulse train. It is therefore fundamentally possible to monitor this time interval between impulses for determining the end position of the door leaf and to derive the signal for reaching the end position if the door leaf is at a standstill.

Delays are noticeable through larger time intervals in the pulse train. It is therefore fundamentally possible to monitor this time interval between impulses for determining the end position of the door leaf and to derive the signal for reaching the end position if the door leaf is at a standstill.
• the reaching of the end position and therefore the standstill of the door leaf is determined by a mechanical stop in that the power consumption of the drive unit changes accordingly, that is to say in In the case of a direct current motor, for example due to the torque requirement which has increased to infinity, a corresponding current consumption occurs.
• This change in the absorbed energy can be determined very quickly, can be used to switch off the drive unit, and can be stored as a mark for the end position of the door leaf.
• the door leaf is deliberately driven into the respective end position and is only controlled with respect to the drive unit after feedback of a mechanical stop that has taken place there.
• This procedure is used at least when the installed door is put into operation in order to determine and save the end positions. Since the increment encoder of the drive unit also stores or counts the pulse number of the increment encoder representing the distance, the subsequent operating movements of the door leaf can be controlled according to this pulse number by the storage, counting and control device.
• the procedure according to the invention comprises an initial phase for ascertaining the end positions of the door leaf in such a way that it is driven from any initial position into one of the end positions, specifically at a low speed or torque of the drive unit.
• the door leaf thus reaches the actuated end position and, in response to the drive or its energy values recorded, indicates the mechanically forced stop state, which is stored as one of the two end positions in the storage, counting and control device.
• the drive direction is then switched over so that the door leaf in turn travels the entire movement distance to the other end position with low drive energy.
• the number of pulses emitted by the incremental encoder is stored as a "movement distance mirror".
• the door leaf In the other end position started in this way, the door leaf is in turn stopped by a stop and the power changes occurring in the drive unit for marking the second end position are stored. If the door leaf is already in one of the end positions during this running-in process (reading in the operating parameters of the movement path), this is recognized as the first end position when the drive unit is running in the appropriate direction or is not perceived in the opposite drive direction, so that the "start-up" takes place arbitrary position of the door leaf "in this case assumes one end position and the door leaf moves back and forth through both movements runs to enter the two end positions in the memory.
• the gate can subsequently be force-controlled on the basis of these entered parameters, i.e. it is driven with high torque or high speed over the majority of the movement to be covered in each case.
• the reduction in the energy quantity entered into the door leaf towards the end of the respective movement sequence is not only useful for a gentle or gentle entry into the closed position, but also for the new marking of the end position in the above sense.
• the monitoring of the time interval between successive pulses, but in particular the electrical energy supply of the drive unit - current as a function of the torque - can also be used to switch off or reverse the movement of the drive unit if the movement of the door leaf is impaired by an obstacle in its path of movement.

• FIG. 1 shows, under the title "Sequence of movements during the measurement run", the phase of commissioning a newly installed door leaf with reading in the number of pulses for the movement distance and the end positions of the door leaf.
• I. Movement in the diagram of speed over distance (v over s)
• v over s an initial movement from a central position of the door leaf between its end positions is assumed and a movement in the direction of the arrow to the left is assumed.
• the movement takes place at low speed and ends with a mechanical stop in the first end position (e.g. closed position of the door leaf).
• “2nd movement” shows the movement sequence of the door leaf in the opposite direction of movement after the start-up in the first end position according to FIG.
• the drive Shortly before reaching the end position recorded first, the drive is switched back to the low speed intended for reading in, depending on the route, in that a few pulses are subtracted from the number of pulses recorded under "2nd movement" for the entire movement distance, so that for the operating speed vmax a lower Str e is specified.
• FIG. 2 shows a possible embodiment of the circuit arrangement in which the drive motor M is shown as a DC motor with an incremental encoder.
• the symbols and their names largely speak for themselves and are basically known in their individual configuration.
• a power supply unit for converting an AC line voltage into a 24 V DC voltage feeds the drive motor via a power unit, a subsequent gear and in particular the door leaf driven thereby are not shown.
• the motor operates, rigidly coupled, an incremental encoder in the form of a perforated disk, which is queried by an electro-optical scanning system in particular and thus emits a pulse for each angular path given by the hole spacing.
• a control processor monitors, among other things, the pulses given by the increment encoder and displays an alarm if they occur without a switch-on command - break-in.

• “Parking aid” is to be understood as a laser device that provides a guideline or a guiding field for the driver of a vehicle as an orientation aid in the case of a garage door, for example when an opening command is given.
