Description

Technical environment

The invention relates to an automatic door, such as a sliding door, a revolving door or the like comprising at least one door leaf, which is drivable by means of a control device via a drive device, and wherein on the inside and / or outside of the automatic door presence sensors are provided for monitoring the passage area the door.

State of the art

Automatic doors, such as sliding door systems are known from the prior art, in which the door program output / automatic and open can be selected. In the door program output and automatic, the door opens to a signal from radar outside or from inside the radar, which automatically closes after expiry of the hold-open time. In door program Open, the door remains open as long as the door program Open is selected.

The closing process is safeguarded by occupancy sensors, which are mounted inside and outside the sliding door system. At each closing phase, the function of the sensors is checked, whereby the complete passage through the door is monitored by the occupancy sensors. If an object is detected during the closing drive, the sliding door opens immediately. The applied mains voltage for operating the sliding door system is permanently monitored by the control. In case of failure of the mains voltage is inevitably switched to the battery voltage. With the help of the stored energy in the battery, the sliding door can still be moved, z. B. the door can be closed and locked. The sliding door can optionally be opened via the button in the event of a power failure.

Such a sliding door system is for example from the DE 10 2006 020 372 B4 known. There, a sliding door system with at least one sliding door leaf is described, which is drivable by means of a driven by an electric control device drive means. The door system is can be used as an escape and rescue route by the drive device is designed so that the sliding door is opened in the presence of an emergency signal to release an escape route and the sliding door system is lockable at least in an operating state by a locking device. A release device is available for unlocking the locking device. In this known from the prior art sliding door system the way is released for people in case of flight.

Another door system is from the DE 10 2010 002 870 A1 known, with this sliding door system also a release for releasing an escape and rescue route is available. The same applies to the known in the prior art DE 10 2010 024 755 A1 , which also provides the function of an escape door, by means of which a person can operate the door drive during the disturbance operation to perform an opening or closing cycle of the sliding door leaf from the indexed by the fire protection function closing position.

These known from the prior art sliding door systems that meet the required features for an escape and rescue route in their function are not suitable for use as a fire door / firewall to vorzuhalten a fire barrier, for example in buildings, as is the case with mechanical fire doors , These act together with mechanical energy storage, which close in case of a fire, the door or the sliding door and seal off the building area such that it is required to strike through fire.

task

The invention thus presents the problem of providing here a door control for an automatic door such as a sliding door, a revolving door or the like, which has the function of a self-closing degree z. B. a fire door or a fire protection, without having to provide provisions and applications for the actual automatic door operation.

solution

According to the invention the problem is solved with the features of the main claim. Advantageous developments emerge from the subclaims.

The additional control according to the invention directs regardless of the set door program on the door control the closing drive at a signal of the signaling device z. B. in case of fire immediately. The additional control separates in this phase of the signal the drive train, that is, that the motor lines or one or two drive trains are electrically separated from the door control of the basic control. The additional control switches to this, so that the additional control and not the basic control of the door control is electrically connected to the drive train.

Optionally, a communication can take place between the so-called basic control and the additional control in order to provide structural components for a redundantly designed control of the additional control in this way.

The additional control can close the door in the phase of the signal, taking into account optional safety sensors connected to the additional control, such as closing area monitoring, occupancy sensors, or even blanking them.

If the presence sensors are ignored in the signal phase, there is a risk to persons during the closing drive. This is to be avoided by the additional control closes the automatic door with a low speed and under load cut-off by motor current. The low speed should be chosen so that a hazard can be excluded normatively. If the closing drive is under evaluation of the safety sensors optionally connected to the additional control, the door can be moved at normal speed. Triggering the occupancy sensors in this closing phase causes the door to stop immediately. If the optional safety sensors connected to the auxiliary control are occupied for an extended period in this phase, the signal is ignored by the control and the door closes at low speed as described above.

If the closing movement takes place without evaluation of the presence sensors, the door closes only at low speed. A personal risk is therefore not given.

The automatic door then locks the closed position via a controllable by the additional control and / or switchable lock, the lock prevents the sliding of the automatic door in at least one position to the entire area of the door. Opening attempts by the door control are prevented by the separation of the drive units.

Are obstacles in the passage area in an emergency z. B. given a fire alarm, so the automatic door opens on the obstacle. According to a particularly advantageous embodiment of the invention, the additional control is designed for the case such that sets a cyclic closing of the automatic door and the door then tries to end the closing process.

A reset or a recommissioning of the automatic door on the additional control can only take place when the emergency closing signal stops, so that then a manual operation of the program switch and / or other switching elements can be made only.

When errors occur on the drive or on the additional control closing is always ensured due to the design, so that the automatic door always closes and locks. The status of the error message can be visually displayed. The safe closure of the system is based on the fact that either a redundancy is implemented on the additional controller or that the additional controller communicates with the basic controller for redundancy.

If an obstacle is detected on defective safety sensors, which are optionally connected to the additional control, such as closing range monitoring and presence sensors during closing, the drive stops. The closing process is automatically restarted with a time delay. After z. If there are five failed attempts, the drive stops at the obstacle and switches off. The number of failed attempts can be changed here. However, if a fire message occurs, it will continue to be cyclically tested.

If there is a continuous release of the optional safety sensors connected to the auxiliary control during the intended closing operation, then this signal is visually and / or acoustically displayed by the additional control unit after a time x. If in this time a signal from the signaling device z. As a fire, then the additional control closes the door, however, at a reduced speed. This speed ensures that a personal hazard is not present. The sliding door is automatically locked after reaching the closed position and the additional control switches off. A new operation is only possible again when the user consciously starts the additional control again and the additional control does not detect a fault in the system.

A critical error would be z. As a failure or a fault in the main computer or a failure or a fault in the main drive. This fall situation would lead to the closing drive being effected, if possible, via the main drive or the emergency drive. If the optional safety sensors connected to the auxiliary control can not be evaluated, the automatic door closes at reduced speed. This reduced speed is chosen so that there is no danger to persons. The automatic sliding door is locked after reaching the closed position and the additional control switches off. A new operation is only possible again when the user deliberately starts the door again and the door detects no error in the system.

According to the invention feature is proposed that for the control of the door as a basic control additional control is provided which is connected to a signaling device, for example with a fire alarm or a smoke detector and triggers the closing drive at a signal of the signaling device immediately regardless of the basic control. The additional control on the automatic door is equipped with a signaling device z. B. a fire alarm panel or a smoke detector, wherein a control of the signal of the signaling device via a host and / or a control computer evaluates, regardless of the set and programmed state of the basic control of the automatic door via the controller causes the immediate closing movement of the door or, for Providing the automatic door as a fire door or firewall, if not via the communication and monitoring of the Movement of the door control a closure of the auxiliary control can be guaranteed. This is ensured by the separation and switching of the drive train from the door control.

Due to this design ensures that the extended by the additional control automatic door can also be used as a fire sliding door or fire protection or can be used. The automatic door does not require the equipment of mechanical means such as a spring-loaded or a weight memory to z. B. in case of fire bring about a fire barrier. In the case of the automatic door according to the invention, this is provided via the electronic additional control.

According to an advantageous embodiment of the invention, the closing movement takes place at low speed and under load shutdown. The automatic door locks automatically when closed. In a further development, the additional control of the automatic door in the event of an obstacle in the passage area causes a cyclic closing drive is performed. If the obstacle in the passage area remains, the door switches off. However, opening by the door control is prevented.

In a further development of the invention occurs in case of failure of the additional control or in case of failure in the main computer, or in case of failure of the power supply, the closing movement of the automatic door via a redundant path to close the door. This ensures that if z. B. in case of fire, the power supply or the drive unit or the controls completely fail, the shutdown is still done.

According to a particularly advantageous embodiment of the invention, an error is displayed optically in case of failure of the controller. A restart of the automatic door can only be done in the absence of a fire alarm. When commissioning the automatic door, this can only be done with manual operation of the additional control. If it is necessary to open the protective door, there is still the possibility to open it manually, whereby a closing mechanism is generally always given by the controller in case of fire.

Another particularly advantageous embodiment of the invention ensures the reliability of the closure to the effect that a safety-related communication between basic control and additional control part of the redundancy is on the additional control and a second part is on the basic control. This has the consequence that a closure or a fire protection with low component costs can be achieved. This also applies if the basic control or additional control is subject to a critical error.

If errors occur on the drive or on the additional control, a closure is ensured due to the redundant design, so that the automatic door always closes and locks. The state of the error message can be displayed optically and / or acoustically.

embodiments

The FIG. 1 shows a door control 1 for an automatic door, such as a sliding door, a revolving door or the like. This comprises at least one door leaf which is driven by means of a motor 2 and / or a motor 3. The door control 1 in this case comprises a basic control 4 and an additional control 5, both of which are connected via a switchover 6 to the motors 2, 3. The switching 6 is in the FIG. 3 and in the FIG. 5 shown in more detail here.

The basic control 4 normally drives the automatic door, unless the switchover 6 is actuated by a redundant system 7 of the additional control 4. With the redundant system 7 is a power supply 9 and a battery 8 and a trigger 10 such. B. connected a fire detector. The redundant system 7 is in operative connection with the switch 6 and is thus connected to the motors 2, 3 and the latch 11. In addition, a closing range monitoring 12 can be connected to the redundant system 7.

If the triggering 10 is actuated as a result of a signal, the motors 2, 3 are disconnected from the basic control 4 of the door control 1 by means of the switchover 6 and switched to the additional control 5 according to the invention. The additional control 5 directly causes the closing movement of the door or the door to use in this way the automatic door 1 as a fire door or fire.

The FIG. 2 shows the additional controller 5 and in particular the redundant system 7 in more detail for an automatic door, such as a sliding door, a revolving door or the like. This comprises at least one door leaf which is driven by means of a motor 2, 3. The door control 1 is connected via the switch 6 to the motors 2, 3 and can drive them normally, unless the redundant system 7, consisting of a battery charge 13, a control computer 14 and a motor drive 15, not the switch 10 is actuated. The system 7 here consists of a main computer 16 and a control computer 14, which monitor each other and so operate the redundant motor drive 15 consisting of motor output stage 17 and emergency 18 and press the switch 6. The system 7 is powered by the power supply 9 or the battery 8, so that a permanent supply is guaranteed. With the system 7 and thus in each case with the main computer 16 and the control computer 14 is directly the trigger 10, via which the signal is received, connected. An optional additional closing area monitor 12 is also connected to the system 7. As already mentioned, the motor drive 15 consists of the motor output stage 17 and the emergency stage 18, which are supplied by the power pack 9 or the battery 8. The supply here is via the switchover 6 in connection with the motors 2, 3.

By virtue of the redundancy contained in the motor drive 15, the motor or motors 2, 3 can drive the motor or motors 2, 3 even if one component, for example the engine output stage 17, fails so that a secure closure is possible.

Furthermore, the lock 11 is connected to the changeover 6, so that it can be controlled by the additional control 5.

If the triggering 10 is actuated as a result of a signal, the motors 2, 3 are disconnected from the door control 1 by the switchover 6 from the basic control 4 and switched to the additional control 5 according to the invention. The additional control 5 will now directly effect the closing movement of the door leaf, taking into account the closing area monitoring 12, to use in this way the automatic door 1 as a fire door or as a firewall to ensure the conclusion. In this case, the main computer 16 and / or the control computer 14 are driven, so that in each case the signal for the motor output stage 17 or an emergency 18 for the commissioning of the motors 2, 3 is passed.

The FIG. 3 shows the switching 6 contained in the auxiliary control 5 according to the invention by way of example. The changeover 6 consists of a voltage changeover 19, a motor changeover 20, a lock changeover 21 and a motor drive changeover 22 which are in operative connection with the system 7 of the basic control 4, the motors 2, 3, the motor control 15 and the battery 8 and the lock is in communication.

The battery 8 and the power supply 9 can be switched by the system 7 via the voltage switch 19 to the motor driver 15. This ensures that the motor drive 15 always with voltage is supplied. When the basic control 4 of the standard door control is disconnected from the motor or motors 2, 3 via the motor drive switch 22 and the system 7, the redundant powered motor drive 15 can drive the motors 2, 3 to close. By means of the motor drive change-over 22, the system 7 selects one or both of the motors 2, 3 in order to perform the closure, so that if one of the two motors 2 or 3 fails, it is ensured that a closure nevertheless takes place.

The FIG. 4 and 5 show in a further embodiment, the door control 1 consisting of basic control 4 and additional control 5, wherein between the additional control 5 and the basic control 4, the possibility of communication is to ensure in this way the redundancy of the additional control 5. The advantage of this design is that component components such as the main computer 16 and the motor output stage 17 can be saved.

The in the FIGS. 4 and 5 described and illustrated embodiment behaves in such a way that when the trigger 10 is actuated as a result of a signal, a Schfießbefehl is given by the additional control 5 via the communication of the basic control 4. This closing movement is monitored by the additional control 5. If it is noted that no closure is effected by the basic control 4, the motors 2, 3 are disconnected from the basic control 4 of the door control 1 by means of the changeover 6 and switched to the additional control 5 according to the invention. The additional control 5 directly causes the closing movement of the door or the door to use in this way the automatic door 1 as a fire door or fire.
