Description

The invention relates to a method for operating a drive unit of a mobile element with a control / regulation and at least one non-volatile memory, as well as a position detection device that provides information on the position of the element over the entire route of the mobile element, which is determined by a reference and stored were. Furthermore, the invention relates to a drive unit which is operated with such a method for operating a mobile element.

By the DE 199 18 414 A1 is a drive unit for a gate with an electromechanical drive motor comprising a gear, by means of the output axis of the gate is movable and has a position detection unit consisting of an electronic control unit and a transmitter with uniform pulse train per revolution, with the output shaft and the electronic control unit interacts, has become known. In order to provide accurate control, which is universally applicable to a wide variety of types of doors, per revolution of an information carrier of the information transmitter is detected in the temporal length pulse detected in the electronic control unit non-volatile storage and further processed.

By the DE 10 2005 039 532 A1 is pointed to a drive unit for a door or a door, in particular a garage door in the way that an electric motor is used with an information transmitter for position detection, which provides the same pulses per revolution, wherein one of these pulses in the time length is changed. All recorded pulses are stored in a non-volatile memory. Further, an electronic control circuit is provided with an electric motor final stage, wherein in the control circuit in at least one memory different variable sequence programs are stored, wherein at least one program, a method for a programmable learning for the opening and closing direction the door, the door, in particular the garage door, includes. Furthermore, at least one further program is present in which the position detection pulses stored in the non-volatile memory are processed according to various methods and / or at least one further fixed program for force measurement and / or variable force adjustment at the main and / or secondary closing edges of the Door, the door, in particular the garage door, includes.

An optoelectronic rotation angle sensor comprising a multi-track digital encoding, an illuminated code disk coupled to the rotational motion of a rotor and a sensor array consisting of a plurality of different wall elements arranged transversely to the direction of movement of the code disk for sensing the encoding of the code wheel Code slice is determined by the fact that at least individual tracks of the codes located on the code disc are multiple and spaced apart, as by the DE 199 44 005 A1 disclosed.

With the DE 196 39 501 A1 An absolute rotary encoder for determining a vane position is disclosed, which is coupled to the output shaft of the electric motor and its data via an intermediate evaluation device to the control unit on. By using the absolute rotary encoder, the sash position is immediately available again even after a malfunction or interruption of the power supply. It is not necessary to approach a reference position and no search run according to this prior art.

In the DE 103 41 297 B3 a measuring system for determining an absolute position of an element moving along a rail of a horizontal sliding wall is described. In this case, a code band located in or on the rail is used, which is detected via an optical scanning system arranged in or on the element. A decoder determines an absolute position of the element based on a signal output from the optical scanning system.

Furthermore, in the DE 38 25 097 A1 a device for measuring the position of a crane and electric monorail system with a code carrier carrying along its length extension multi-valued code marks described. The code carrier cooperates with a code reading device. So that the code reading device does not give rise to erroneous reading results in relation to the code carrier, the code marks with the code carrier are arranged in a single line and formed in such a way that the code marks forming a code word are each directly adjacent to one another lie, long since the entire code carrier are arranged uniquely.

Of great importance in operating a portable element by a drive unit is always to know the exact position of the element in both the opening and closing movement at any time and at any travel position. This is especially true of greatest importance if no mechanical limit switches are available on such a system.

It is therefore an object of the invention to always know the exact position of the element in a movement of a movable element. Errors of the position determination arising and / or occurring during the position measurement should be canceled by a distance correction, without the mobile element having to move into a stop or into its pulling position. The use of limit switches should therefore be expressly waived.

The object is achieved by the method according to claims 1 and 2 and by a device in the form of a drive unit according to claims 10 and 11. The subclaims have further structural configurations and various possible applications of the solution principle according to the invention to the content.

At least once during an opening or closing travel of a portable element, which may be designed as a gate, door, garage door, sectional door, swing gate or the like, a check of the exact position should be performed. Should it turn out during the check of the current position of the mobile element that there is a deviation of the current position from stored reference information of this position, a correction to the stored reference value is automatically carried out. Such a correction may be carried out at arbitrary locations based on reference points, reference pulses or reference information along the route. The position information is constantly updated, for example, by a position detection device currently, with a suitable position detection device in a variety of designs z. B. with code strip or black and white marks or holes or the like may be formed.

As a result of a first reference travel, the end positions and the distances for particular reference information have become known to one another by the position detection device and have been stored in a non-volatile memory of the control system. This means that the homing must be performed for both the opening and the closing direction of the mobile element. To determine the reference information, for example, pulses, markings or the like can be detected. In the event of an error occurring during normal operation of the portable element, unnoticed by the user, a correction is automatically carried out by the method according to the invention. Such a correction quantity is dependent on the information of the position detection device used.

In the case of a position detection device which supplies pulses, for example, such a correction quantity is dependent on the pulses per revolution of the position detection device. It can be announced for this purpose, for example, the use of a code disk. In this case, for example, part of the information or pulses can be used as a correction variable so that no overflow can occur. This reference position is compared with a read-only memory in which the reference information determined during reference travel is stored. In this case, for example, in a position detection device which is designed as an incremental encoder, the increments during a movement to the previously determined and stored reference information or the like to behave synchronously. As a result of the automatic comparison of the stored reference information, an asynchronous behavior of the information can be used to easily correct the stored reference values. Thus, a permanent review and corrector is possible on the entire route. It is within the meaning of the invention that, however, only at certain positions a review takes place and if there are deviations a correction is performed. In this case, preferably this information and data are stored, so that it can be checked again and again in the automated operation of the mobile element, whether the correct position is maintained during operation.

In order to be able to carry out such a method, it is necessary for a detection of the information or signals to be carried out so that there is always a clear result. For this purpose, it is necessary that the information provided is such that misinterpretations are excluded or automatically filtered out and thus not used to determine the current position. This is necessary, for example, for pulses, both rising and falling edges. Likewise, a time measurement is carried out at the same time on the guideway. The reference information is subsequently generated from this processed data and information. Particular attention must be paid to the dynamics of such a mobile element during the acceleration phases or the deceleration phases over time. This leads simultaneously to the fact that, for example, a dynamic correction during the entire route of the mobile element can be performed.

In a further preferred embodiment, it is possible that only at selected reference positions a check is performed.

In order to apply such a method, it is necessary that a drive unit be used as a hardware component having a control unit having at least one nonvolatile memory in which detected reference values are stored. In such a memory, the corresponding information of the reference runs "open" and "closed" are stored.

By the drive unit, in conjunction with a suitable position detection device, it is possible to detect an entire movement of a movable element in the form of a gate, a door or the like completely over its entire path through the position detection device. At the same time, this also creates the possibility of controlling different parameters over the entire travel path of the mobile element and, if necessary, of correcting them by program sequences or program steps. By an absolute position detecting device, it is possible to know the absolute position of the mobile element on its entire chassis at any time.

Such a position detection device can consist, for example, of an information transmitter comprising an information carrier and a detection system. A suitable position detection device may be, for example, an incremental encoder which has a circular information carrier. In this case, in a first preferred embodiment uniform information contents are formed at regular intervals on the circular circumference of the information carrier or data transmitter. However, in order to have an absolute position detection means, it is necessary that a particular reference signal or reference information is output every revolution of the information transmitter. This is made possible, for example, by an uneven spacing of the information contents or by an uneven information content. The data provider supplies by a non-uniform distance a clear information content in each complete revolution of the information carrier. By this reference point, it is possible to determine exactly in both directions of rotation of the position of the movable element at each point, because the operating principle of the position detection device based on the fact that per revolution of the data transmitter in the time length changed pulse or information is detected. This is for example supported by the fact that the respective positive edges and negative edges are detected and evaluated separately depending on the direction of rotation.

By such a drive unit described above in combination with a position detection device, it is possible a movable element, for example in the form of a gate, wherein the gate can be made in one or more parts, along lateral guide rails vertically or horizontally or in one embodiment as a hinged door or rotary wing be formed so that a universal drive unit is used, which is coupled to one of the previously described position detection device.

Such a drive unit can be constructed very compact and be carried out regardless of the size of the mobile element. To ensure universal applicability, it makes sense that a standardized mounting option on the drive unit is available. As a result, a quick installation on different spatially variable elements is possible.

The invention is illustrated by way of example with reference to the embodiments shown schematically in the drawings. It should be noted in principle that in addition to the detection and processing of pulses and other absolute detection devices that can detect at certain points or points of the route by reference information a very unique position, fall under the inventive idea.

For the sake of clarity, in the following description of the selected preferred embodiments will be only talk of pulses, the invention, however, refers to all other possible embodiments of position sensing devices that can provide reference information in addition to the normal information about the route of the mobile element.

In the 1 is a possible signal detection for the example of a position detection device 122 delivered pulses. In a first block 1 a signal acquisition is carried out with a subsequent signal debouncing 2 accompanied. The signal debunking 2 is necessary for a clean, unambiguous impulse to be able to avoid false interpretations of an impulse or the like. In the subsequent block 3 a flank detection is performed. This causes that in the block 4 there is a counter that counts all positive edges. While in the block 5 there is a counter that detects all negative edges. Such a determination and evaluation of the edges according to "rising" and "falling" is extremely important since it also generates a time measurement. The separate execution and counting of the flanks makes half sense, because always on a rising edge a falling edge must come for a pulse. This is the only way to generate a clean impulse and thus a clear impulse. This happens in blocks 6 and 7 where the temporal result is automatically determined from this information. After a comparison, this information is obtained in the block 8th a usable pulse generation brought about. This also has the consequence that the reference pulses which are contained in the normal pulse sequence are filtered out here. This is particularly important in a dynamic operation with accelerations and delays of great importance, since only so a comparison of the pulses over time is possible. Normally, the ratio of the positive and negative edges always gives a ratio of 50:50. However, it must be remembered that relays or other components of the control / regulation can bounce here as well, or that switching operations are not carried out properly, so that it is extremely important, here the exact and unambiguous corresponding reference pulses 58 filter out.

Such a reference pulse generation can the 2 be removed. This is in the block 9 a measurement of a first delivered time pulse of the position detection device 122 carried out. This is followed by an evaluation of the positive and negative edges in the block 11 carried out. At the same time, in addition to the first impulse, the second impulse is also transmitted over the block for safety reasons 10 recorded and also afterwards in the block 12 an evaluation is carried out with regard to the positive and negative edges. Both the first and the second pulse are compared with each other and in the presence of a reference pulse 58 this will be automatically in the block 13 extracted out. Will not be a reference pulse 58 determined, the information is sent to the block 14 where a direction of travel detection 18 he follows.

In the presence of a reference pulse 58 is according to the block 13 this to the direction detection 18 passed. When deciding if a reference pulse 58 is present, the direction of travel is to be distinguished, namely, whether it is an opening or closing travel of the mobile element, as they are performed differently by the kinematics, which is due to the geometry of the mobile element. This information regarding the opening and closing drive is thus also stored. When driving direction detection is only the determined reference pulse 58 edited in chronological order. So will in the subsequent blocks 15 and 16 for the direction of travel "up" and direction of travel "to" a count of the reference pulses 58 then made in the memory 17 are stored and thus virtually as Urreferenz or reference pulse 58 due to the reference runs "open" and "closed".

Separated according to the directions "up" and "to" according to the blocks 19 and 20 be in the blocks 21 and 22 the determined reference pulses 58 recognized at their traditional waypoints and in the following comparison stages 23 and 24 stored for the opening and closing direction. In case of deviation, a correction will be made in the block 25 determined. This correction of the reference pulses 58 can be reflected in both a positive and a negative correction. In both cases, there is a specific reference pulse 58 has been clearly identified and it may be in the absence of a deviation according to the block 26 a smooth continuation without position correction can be performed.

However, if a deviation has been determined, then this is determined dynamically or in predefined fixed steps according to the block 27 corrected. When corrected, the value of the current stored reference position replaces the current information of the position detector 112 set. A storage of the current information is not performed in such a case. Rather, there is a correction during the opening or closing drive, so that the operator of the mobile element of this correction perceives nothing.

Due to the fact that during the run of the drive unit 31 for an automated mobile element a correction of the possibly occurring deviation of the current position, which may be of different nature, compared to the stored reference position, with a time and path correction the greatest possible safety and thus a trouble-free operation of a mobile element, without the case of the carriage for example, a gate or the like must be pressed in a stop or in a pulling position executed.

However, in order to be able to carry out such a method, it is necessary that a position detection device 112 is available, which also provides reference information.

In the 4 is a first preferred embodiment of the drive unit 31 played. This is an engine 47 with a gear 32 so actively connected that a drive shaft end 37 on one side and on the other side a drive shaft 33 is available for driving the portable element. To the transmission 32 is about fortifications 35 dissociates an electrotechnical board 34 which are essentially used for identifying and connecting an information provider 36 information provided. This is on the board 34 also a device 38 in a preferred embodiment, as a light barrier with a leg 39 is trained. In the space between the light barrier 38 dive the above information content 28 . 40 . 41 . 42 . 43 . 44 . 45 . 46 an information carrier 29 one.

An information provider 36 , contrary to the embodiment according to the 4 no angled information content 28 . 40 . 41 . 42 . 43 . 44 . 45 . 46 has, but is designed as a disc, the 6 be removed. Here are the information content 40 to 46 designed as uniform information content, whereas the information content 28 must be termed nonuniform, as it is substantially wider than the other uniform information contents 40 to 46 is. Through the detection of the device 38 can be a contactless scanning of the information content 28 . 40 to 46 respectively. Because of the information content 28 larger dimensioned, it has, for example, the information content 40 a short distance away. This irregularity becomes an impulse in the device 38 generated, which has a greater temporal length compared to the pulses, by the information content 40 to 46 be generated. Such a temporal course give the 7 and 8th again. The difference in the 7 and 8th lies in their direction of rotation 48 and 49 , In the figure representations 7 and 8th it is thus a revolution of the information provider 36 about the timing t.

In a further preferred embodiment is in the 9 another information provider 36 shown in which the information content 40 to 46 are the same and the information content 28 is subdivided into two smaller but equally sized informational content, pointing simultaneously to the information content 46 a greater distance. Like the representations of the 10 and 11 can make very clear, even in such a preferred embodiment according to the 9 at one revolution of the information provider 36 a clear detection of the different types of information content 28 done over the route.

Depending on the direction of rotation of the motor 47 can by the direction of rotation 48 in the 7 and 10 For example, be shown an opening trip of the mobile element. To the same extent would then 8th and 11 with the direction of rotation 49 represent the closing movement of the mobile element.

In the embodiment of the drive unit 31 according to the 4 would thus, for example, via the information provider 36 at each revolution of the information provider 36 Pulses are generated due to the uniform information content 40 to 46 have a same time course. Only the non-uniform information content 28 according to the 7 . 8th . 10 and 11 can be either shorter or longer. By this exemplary training, it is possible that by the different types of information content 28 corresponding reference pulses 58 be formed out. These reference pulses 58 are used in particular for the exact position determination of the mobile element via its travel path. Already at this point it is clear that even with a shutdown of the drive unit 31 and again start exactly the last observed position of the ortveränderlichen element found and taken again.

So that the drive unit 31 During a first startup, the exact route can be determined, a reference run in the opening and closing direction is performed. For this purpose, a corresponding program within the drive unit 31 activated. The detected pulses or the like are stored in a non-volatile memory and simultaneously from the total pulses, according to the methods already described, the corresponding reference pulses 58 filtered out and processed accordingly and then processed. Such a reference journey over the way or the time shows the 12 in which in this embodiment pulses 50 to 57 be generated. The impulse 53 is much shorter in its length and forms with the gap to the impulse 52 altogether the reference momentum 58 ,

In the 13 In one possible embodiment, this is a program sequence for operating the drive unit 31 have been shown by a flowchart. For the sake of clarity, it is no longer at this point on the procedure of 1 to 3 although these method steps are applied to all movements of the mobile element. Thereby becomes a command 59 given to open the mobile element. Based on the information provided by the information provider 36 become the impulses 50 to 58 measured and in the stage 63 the pulses are counted. About filtering in the stage 64 becomes the reference pulse 58 in the stage 65 extracted and stored. In the stage 66 the program will be both the reference pulses 58 as well as the other impulses 50 to 57 saved. When reaching the opening position 67 of the mobile element, the reference travel thus completed is completed.

In the same procedure is also the closing of the mobile element by a reference movement 76 according to the procedure 14 determined. This is necessary because, depending on the version of the ortsveränderlichen element here a completely different shape of the route over time can result. By a start command 68 The movable element is moved out of the open position and it will be the resulting pulses in this embodiment 50 to 58 in the stage 71 measured. In the subsequent stage 72 These pulses are counted and in the stage 73 the contained reference pulses are filtered out. In the stage 74 These filtered-out reference pulses are stored separately and in the stage 75 all pulses are stored. With the program point 76 will be the reference journey 76 completed.

According to the 15 may be a possible program sequence for operating the drive unit 31 be performed with a not displaceable element, not shown. For simplicity, in this flowchart, both the opening travel with the command 59 and the closing drive with the command 68 alike. After starting the drive unit 31 will be in the next program level 62 . 71 the pulses measured and in the next program level 63 . 72 counted accordingly and then in the stage 64 . 73 the reference pulses are filtered out. In the subsequent stage 78 there is a pulse comparison, so that a pulse deviation in the stage 79 can become vacant. If this is the case, then, according to the method described above, via a program or the like after a correction comparison 77 in the correction stage 80 a correction was made. If there is no correction specification, then according to the command 81 another measurement on the path of the pulses 62 . 71 performed.

Another preferred embodiment of the drive module 31 will be in the 5 shown. This drive module 31 is designed so that it is constructed as a very compact unit, in which case the position detection device 112 is interchangeable. The position detection device 112 is from a housing 103 enclosed. On the case 103 is a connection terminal 114 for connection to a control unit, not shown. Further, located on the housing 103 a sensor element 113 , which in conjunction with a release 115 a shutdown of the drive unit 31 , when the release is activated 115 , causes.

Distanced by spacers 111 is the case 103 present on a mounting device that has a base leg 108 in which on the one hand a slot 107 and a detent receptacle 106 are included. Starting from the baskelkel 108 are a mounting piece on the side 110 and a thigh 109 available. The spacer elements 111 are with the mounting piece 110 connected. At the output shaft, not shown here is a drive wheel 104 attached, over which the mobile element can be driven. Via terminals 118 becomes the engine 47 supplied with appropriate electrical energy.

Differently formed position detection devices, the reference information z. B. by black / white markings or codestrips or the like can also be used.

Like the representations of the 4 and 5 make clear, the drive unit can 31 be constructed in different embodiments, wherein in these embodiments, the position detection device 112 are designed as a rotating disk or as a bell.
