Before the commencement of the learning journey, a self-calibration of the motor control takes place, and the characteristic data is detected and stored in the memory.

Description

The invention relates to a method for the automatic operation of a mo Torically operated partition system according to the preamble of the patent claim 1.

DE 44 24 660 C1 describes a method for automatic operation a motorized partition system become known. The Partition system has individual elements in one on the ceiling attached guide rail are guided horizontally. Further a station is provided, in which the individual elements can be accessed by means of a switchable coupling device can be moved by motor in the parking position, the coupling device being operatively connected to a drive means stands, which is driven by a motor. To control the motori a programmable logic controller (PLC) is provided for operation see. The known method sees one before automatic operation Learning drive before, in which the number, the closing and parking positions of the Ele elements and the length of the route are determined and saved.

It has become more extensive especially in the case of door systems Expansion shown that the function is not in the ge desired dimensions is given. Depending on the outside temperature operational faults that may require manual intervention nen.

The object of the invention is to provide a method for automatic loading drive to provide a partition system in which a ma manual intervention is largely avoided, while at the same time Maximum security should be given.

This object of the invention is indicated by that in claim 1 Features resolved. Advantageous embodiments of the invention Procedures are specified in the subclaims.  

The self-calibration provided according to the invention makes criteria rien detected, which enable the PLC to z. B. select rend a circumstance interfering in the displacement process, the Stop the system immediately, with no other for the door movement usual monitoring devices such. B. radar sensors etc. necessary are. If a static error occurs, e.g. B. the failure of a functional means, the PLC can do this based on the detected and saved criteria Corresponding function-sensitive error messages indicate what the service of such systems is greatly facilitated, such errors messages for service purposes can also be saved in the PLC or elsewhere can be saved and retrieved at a later time or to a central office are communicable.

According to a further feature of the invention, self-calibration takes place the engine control advantageously by starting the coupling device from the boundary marks assigned to the guide rail of the individual elements. This determines the engine-dependent criteria.

According to the invention it is also advantageous if before or during the Learning trip a self-calibration also takes place at the coupling device which detects and stores the key data necessary for operation the coupling device at least one termination criterion for the termination a coupling process when static, dynamic errors occur and form drift errors. This ensures that the cup pel process is specifically monitored. Self-calibration of the dome device takes place according to a further feature of the invention, namely by engaging the coupling device. This means that ma the component-specific characteristics ten particularly determined, with simultaneous stiffness e.g. B. detected by abrasion or pollution, d. H. it finds one Dynamization of all parameters instead.

The control program is particularly clear if According to the invention, the dynamic for detecting the parking position Termination criterion of the partition system is used.  

It is particularly easy to adapt to different partition systems given if the door type of the respective element during the learning is detected according to the invention.

The learning trip can be carried out particularly reliably if according to the Invention during the learning drive when the closed position of the resp gene element the engagement of the coupling device sensory and / or is monitored by evaluating a further termination criterion and if after a preselectable number of failed attempts e.g. B. Failure safety, an error alarm is triggered or if the Coupling device the respective closed position is saved. This ge ensures safety for people and material.

Occurs during the learning drive due to a failed snap lock ches the coupling device on a fault alarm, according to the inven First, motor one from the current position by one preselectable deviation Δ approached reduced test position and from the coupling device for a preselectable number of repetitions repeated locking attempts programmable in number. If these snap-in attempts also fail, the pre-selectable number of repetitions the test position of the dome device motor shifted in preselectable increments. Then be Attempted snapping again and preselected when exceeding one then an error alarm is triggered, or at a successful snap-in attempt, the found true test position as that associated closing position stored for the element concerned.

Are the modes of operation according to a feature of the invention without previously The learn run cannot be activated, so it is very reliable given.  

According to another feature according to the invention ter learning trip, but before the intended motorized shift self-calibration of the elements of the partition system Approach the coupling device to that assigned to the guide rail Limiting marks carried out, and the saved closing position NEN according to the detected length of the route for the purpose of com to compensate for temperature-related changes no functional disturbances caused by temperature fluctuations occur more.

When moving the elements according to the invention, the Locking the coupling device sensory and / or by evaluation of the saved termination criterion is monitored and after a preselection A number of failed attempts triggered an error alarm. If successful chem snap the coupling device becomes the respective element Appropriate closing or parking position approached.

According to the invention, it is during operational motorized movement the door elements of the partition system are advantageous if fiction according to which the dynamic behavior of the displacement movement is detected and when the saved termination criterion is exceeded initially the shifting process is interrupted and after a preselectable time span is resumed, only after exceeding one predefinable number of faults an error alarm is triggered.

Injuries caused by traversing are effectively excluded the process as such is initially only interrupted and after a definable period of time, the partition system again Traversing process until a predefinable number of start-up attempts Chen is exceeded, whereupon an error alarm is triggered. Should However, if it is a serious mistake, be the entire system is shut down if an error occurs, so that it can only be restarted by authorized personnel is (single fault safety).  

According to the invention, the coupling device moves during operational mode in the event of a failed snap-in attempt on the individual door element is first motorized from the target position by a preselectable Deviation decreased test position, being at the location concerned a selectable number of repetitions of the coupling device Snap attempts is carried out. When exceeding the preselectable The number of repetitions becomes the test position of the coupling device moto shifted in preselectable increments. Only when crossing An abort criterion triggers an error alarm that is displayed locally shows and / or who is reported to a higher-level central office that can.

The invention is now based on the processes during the learning trip and when moving the elements as intended explained.

A self-calibration of the engine control is carried out before the learning run begins carried out. Characteristic data are detected, which are for the automati operation of the partition system at least one termination criterion for stopping the sliding movement of the coupling device at Occurrence of static, dynamic errors as well as drift errors and then form get saved. This happens, for example, that the Kup Limit device associated with the guide device starts. The changing motor current or the on drive change of mechanical limit marks occurring Speed serves as the basis for the termination criterion. While the motor current occurring as a criterion for the late tere monitoring of static errors, e.g. B. the failure of the engine or the voltage supply and for so-called drift errors the open-circuit chip can be used for later operational monitoring.

In addition to deriving electrical parameters, sensors can also be used are used to detect the deviations.  

The coupling device is also activated before or during the learning trip subjected to a self-calibration in which characteristic data is detected and ge stores that are necessary for the operation of the coupling device at least another termination criterion for canceling a coupling process if static, dynamic errors and drift errors occur. Most of the time, the coupling devices are electrical devices trained who engage in door segments, so that the termination criterion can be derived from the electrical parameters. Deflection It is important that the criterion is sufficiently informative about the order proper function of the coupling device and a successful intervention delivers. In addition to deriving electrical parameters, of course sensors are also used that detect a deviation or the loading detect driving condition.

The self-calibration of the coupling device can also be done by a Coupling process of the coupling device take place, i.e. the determination of the states "extended", "retracted" and the query in the received state whether a door segment was picked up, which corresponds to a sensor is detected.

During the learning drive, the dy Named termination criterion of the partition system used, see above soon the dome reaches the Element station. This can ent neither by deriving the current position in relation to the geo metric route conditions or via sensors or switches the door element station area can be activated.

The door type of the respective element is detected during the learn run animals. This is done by sensors that are uniquely assigned to the door type characteristics.

Also during the learning drive when the closed position of the each element, the engagement of the coupling device sensory and / or monitored by evaluating the further termination criterion, so that after a preselectable number of failed attempts, an error alarm triggered or if the coupling device clicks into place, the each because the closing position is saved.  

If the attempt to lock in during the learning drive fails, the Coupling device first motorized in one of the current Po test position reduced by a preselectable deviation and the attempt repeated. According to a preselectable repeat the coupling device carries out renewed snap-in attempts speaking of a preselectable number of repetitions. Were the one rest attempts unsuccessful, so the test position of the coupling device Motor-driven shifted in preselectable increments, then again Attempted snapping attempts and when exceeding a preselectable Abort criterion triggered an error alarm. Has been a valid closing position determined by a successful snap-in attempt, the found test position as the corresponding to the element concerned Closed position saved.

Only after you have completed the learn run and saved the parameters different operating modes can be activated.

After a learning trip has been carried out successfully, before the be Moving the elements of the separator in accordance with the mood wall system carries out a self-calibration. This is done by An move the coupling device to that assigned to the guide rail Boundary marks.

Then the closing positions saved during the learn run are removed according to the detected length of the route scaled to tempera compensate for door-related changes.

Then, according to the selected mode, opening the ge whole or part of the door front of the partition system, one inspection of the cell as well as a closing trip, the motorized movement of the Elements are done. According to the basic mode Open or Accordingly, the process begins with the closing or the Parking position of the relevant logically first element. Here is the Locking the coupling device sensory and / or by evaluation of the termination criterion is monitored and after a preselectable number of Failed attempts triggered an error alarm. Is the engagement process the Kup  succeeded, the corresponding to the respective door element approached closing or parking position.

During the operational moving of the door elements of the partition system, the dynamic behavior of the ver sliding movement detected and when the termination criterion is exceeded first the shifting process is interrupted. After a preselectable Time period, the shifting process is started again, after A fault alarm is exceeded if a predefinable number of faults occurs is triggered.

If the coupling device fails to snap into place first by motor one from the target position by a preselectable deviation reduced test position and the dome device according to a preselectable number of repetitions of latching search carried out. If the number of snap attempts exceeds the pre selected number of repetitions, the test position becomes the dome device motor shifted in preselectable increments and only when If an abort criterion is exceeded, an error alarm is triggered.

The PLC can be connected to a higher-level control center, the Ser vice and / or alarm function. Occurs in the operation of the partition wall stemes an error alarm due to a malfunction, the forwarded to the higher-level control center for further evaluation be det.

The operating modes are local and / or from the parent center selectable, with an existing local operating mode selector switch can be switched ineffective by the higher-level control center. This will it can also be used in safety-relevant areas if the head office or the PLC is networked with an access system.

From the higher-level control center, the operating parameters are both can be queried and specified.  

Status messages are saved in a log for service purposes worries about the service personnel in the form of a longer period service work to facilitate.

Furthermore, the method is able to recognize whether within the separation wall system an element is designed as a rotary wing, and whether this Automated rotary wing, d. H. provided with an appropriate drive is.
