description

The invention relates to a method for controlling a motor drive of a door or the like, with programmable control hardware with a computer, using a programmed learning process.

In a control of an electromechanical swing door drive known from DE-OS 3 935 173, the use of a learning program is already known.

The tutorial runs in the initialization phase when the system is commissioned on site. There it is used for self-learning recording of the type of door used, i.e. one or two leaves, with or without a rollover, pendulum or hinged leaf, etc.

In the case of known door drives, the closing direction of automatic door drives is set via a separate DIL switch. A separate control input and corresponding hardware expenditure are required for this.

In other known automatic sliding door drives, depending on the desired closing direction, the door leaf is optionally connected to the lower or upper run of the drive belt running over two deflection rollers in order to set the closing direction. This requires a special connecting plate that is shaped so that it is suitable for both types of fastening or two differently shaped sheet metal parts must be used. The installer must ensure that the correct mounting or use of the correct sheet metal part is carried out. This is a disadvantage. In addition, with sliding door drives it is not always possible to connect the door leaf to the upper part of the drive belt. This applies particularly to drives in which the motor and control are mounted between the carrier or the building wall and the drive belt and the drive length and installation depth are to be kept low.

The invention is based on the object of using a control method of the type mentioned at the outset for entering the closing or opening direction or parameters dependent thereon while minimizing the use of hardware.

According to the invention, the object is achieved in that the learning or the direction of closing or opening or parameters dependent thereon are or are detected in a self-learning manner with the aid of the learning process.

The hardware expenditure is minimized by the self-learning detection of the closing or opening direction. The operator can be installed regardless of the closing direction of the door. With sliding doors, the connecting plate between the drive belt and sliding sash can be coupled to the lower run, regardless of the closing direction. With swing door drives, assembly can also be carried out as standard, regardless of the opening direction of the door. The assembly effort is universally reduced for different applications. The self-learning detection of the closing or opening direction or the parameters dependent on it can take place after installation and connection of the system on site during commissioning.

In preferred embodiments of the method, a sequence of steps a) to d) according to claim 2 is provided in the learning process, the door wing according to step a) can be set by hand. Steps b) and c) take place e.g. with motorized drive of the door leaf. The door leaf preferably runs in its end positions on stops, e.g. End position buffer, so that the door is stopped mechanically. Step d) can take place in the computer; the closing and opening direction determined in this way and parameters dependent thereon are stored.

The learning process is advantageously started by pressing a learning button. The motorized drive can be activated by pressing the learn button by supplying the drive with power immediately or after a specified waiting time. During the specified waiting time, steps of the learning process can be carried out that do not require the motor to be energized.

In a special embodiment of the method it is provided that with the aid of the learning process, a partial opening width of the door leaf for a special operating mode, e.g. the winter opening of winter operation is self-learning. Steps a) to d) are preferably provided according to claim 4. Step b) can take place according to claim 5 or 6, wherein the direction is reversed before reaching the end position if it is determined that the direction is not the closing direction or opening direction.

The learning process for detecting the partial opening width can also be started by pressing a learn button. The above-mentioned reversal of the direction according to claim 5 can also be carried out by pressing a learn button, preferably by pressing the same learn button.

The learning process according to the invention for detecting the closing or opening direction and dependent parameters is preferably integrated into a learning process with which other parameters, such as door weight, door type, etc., are also recorded in a self-learning manner. With the start via a learn button, several learn processes can be started at the same time. The learn button can be multifunctional. It can be operated several times with specific functions during the learning process.

Matically driven revolving door with left-hand hinging, the revolving door being shown in the open and closed positions.

The sliding door systems in FIGS. 1 to 3 are each one-wing. In its end positions, the sliding sash 1 comes with end position buffers 7 and 8 each. 1 and 3 are left-closing. This means that in FIGS. 1 and 3 the left buffers 7 are designed as buffers for the closed position and the right buffers 8 as buffers for the open position. In contrast to this, in the case of the right-closing sliding door in FIG. 2, the right buffer 8 is designed as a buffer for the closed position and the left buffer 7 as a buffer for the open position.

Regardless of the closing direction of the sliding door, the design and arrangement of the drive in FIGS. 1 to 3 is the same. The drive has a drive motor 2 and an electronic control unit 3. The drive 2 interacts with an incremental displacement sensor 9 which, in the exemplary embodiments in the figures, is coupled to the motor shaft at the front end of the drive motor. The output shaft of the motor 2 drives a drive belt 5 which is guided around the deflection rollers 4 by the output shaft being coupled to one of the deflection rollers 4. A connecting plate 6 is fastened to the lower run of the drive belt 5, to which the sliding sash 1 is preferably connected via a screw connection.

The drive with these components is arranged above the door leaf 1 on the wall or a wall-fixed support. The arrangement of the drive is relative to the end position buffers 7, 8, regardless of whether the sliding leaf 1 is left-closing, as in FIGS. 1 and 3, or right-closing, as in FIG. 2. The connecting plate 16 is connected to the lower run of the drive belt 5.

By programming the control according to the invention with the aid of a learning process which is explained in more detail below, the drive is set such that, in the case of left-closing sliding doors in the illustration in FIGS Sliding doors as shown in Fig. 2 drives when closing in a counterclockwise direction and when opening in a clockwise direction.

The entry of the closing or opening direction is self-learning on commissioning. The learning process proceeds as follows:

After installation and connection of the system, the fitter presses the learn button on the control unit 3, whereby the learn program is started. A waiting period predetermined in the program now runs, during which the drive motor 2 remains de-energized, so that the fitter has the opportunity to carry out any further necessary work steps. During this waiting period, the fitter pushes the door leaves into a position near the closing position by hand. He then removes any obstacles from the door's range of motion.

After the waiting time, the drive motor 2 moves the door leaf 1 in a specific direction A, which is predetermined by the learning program and by the connection direction of the motor.

The learning program can be designed so that the closing position is first searched for. First, the path S1 is measured, that of the door leaf

1 to a first anchor point in direction A, i.e. to buffer 8.

Then the direction of rotation of the motor

2 turned over by the program so that the door leaf 1 moves in the opposite direction B. Now the distance S2 is measured, which the door leaf 1 covers to a second attachment point in direction B, i.e. to the buffer 7.

The closed position or the closed direction can then be determined from the measured distances S1 and S2, since the door leaf 1 was in the immediate vicinity of this closed position at the time of the start and the control direction is known to the learning program (see FIGS. 1 and 2):

If S1 is smaller than S2-S1, the door is in the closed position in direction A, i.e. in the start direction (Fig. 2).

If S1 is greater than or equal to S2-S1, the closed position is in direction B, that is, in the opposite starting direction (FIG. 1).

The program described can be used for single-leaf and double-leaf sliding door drives as well as for swing door drives with a closing position stop and swing door drives.

The revolving door shown in FIG. 4 is a DIN-left swing leaf 10. In the closed position it stands on the closing stop 17 on the door frame side. In the open position it stands on a wall stop 18. The drive of the door is not closer in FIG. 4 shown. In accordance with the sliding door drives described above, it has a drive motor, an electronic control, an incremental displacement sensor and a corresponding drive coupling between the drive motor and the wing 10. The output shaft of the drive motor is preferably coupled to the door leaf 10 directly in the axis of rotation region 11. The tutorial during commissioning captures the closing or opening direction in a corresponding manner, as with the sliding door systems described above.

The learning process is also started by pressing the learn button. The waiting time then expires, in which the fitter brings the door leaf 10 close to the closed position and removes any obstacles from the movement area of the door leaf. After the waiting time has elapsed, the drive motor is energized and the door leaf 10 is first moved in direction A and then in direction B, in each case up to the end stop 18 or 17. When moving in direction A, the angle of rotation W1 is measured, and when moving in direction B, the angle of rotation W2 is measured. Then W1 and W2 are compared in a corresponding manner, like S1 and S2 in the previously described sliding doors of FIGS. 1 and 2, and the closing or opening direction is determined and stored.

opening width, e.g. For winter operation, without realizing additional hardware expenditure in the control, a modified learning program is used, in which the learning button, which is used to start the learning process, has a double function. The learning process then proceeds as follows for the sliding door shown in FIG. 3:

After installing and connecting the system, the installer presses the learn button. Immediately afterwards, a predetermined waiting time expires, during which the drive motor 2 remains de-energized, so that the fitter has the opportunity to carry out any further necessary work steps. During the waiting period, the fitter pushes the door leaf into the desired winter opening position by hand.

This opening width must be equal to or larger than a minimum opening width specified in the program, e.g. At least 60% of the maximum opening width, otherwise the winter opening width specified by the program is automatically set after the waiting period when the motor is energized. During the waiting time, any obstacles are removed from the movement area by the installer.

After the waiting time, the drive motor 2 is energized. He first moves the door leaf 1 again in the direction A. The path S1, which the door leaf 1 travels, is measured.

As long as the door leaf 1 moves in direction A, the fitter can reverse the direction of movement of the door leaf at any time by pressing the learn button and thus inform the program that the desired closing position is in direction B. The reversal point X can be selected by the installer by pressing a button while moving in direction A before reaching the end position.

If no key is pressed, stop 8 in direction A is assumed to be the desired closed position and distance S1, which has been traveled there, is saved as the winter opening distance.

If the desired closed position, as shown in Fig. 3, is in direction B, i.e. if the learn button is pressed and the direction of movement of the door leaf 1 is reversed, the distance S2 is measured, which is from the reversal point to the stop 7 in Direction B is covered. The distance S3 which results from the difference S2 to S1 is then stored as the winter opening width (see FIG. 3).

In a corresponding manner, other partial opening widths, e.g. for pharmacy creation, etc., self-learning. The detection of partial opening widths for special operating modes is possible in a corresponding manner with drives for sliding and revolving doors. Applications for multi-leaf sliding and revolving doors as well as for swing doors are also possible.
