EP3130736B1 - Set comprising an automatic door, such as a sliding door, a revolving door or the like, and a signalling device, for example a fire alarm control panel or a smoke detector - Google Patents

Description

technical environment

The invention relates to a set comprising an automatic door, such as a sliding door, a revolving door or the like, and a signaling device, for example a fire alarm control panel or a smoke detector, the automatic door comprising at least one door leaf which can be driven by means of a control via a drive device, and wherein presence sensors are provided on the inside and/or outside of the automatic door for monitoring the passage area of the door.

State of the art

Automatic doors, such as sliding door systems, are known from the state of the art, where the door program Exit/Automatic and Open can be selected. In the Exit and Automatic door program, the door opens in response to a signal from the radar outside or from the radar inside, and closes automatically after the hold-open time has elapsed. In the Open door program, the door remains open as long as the Open door program is selected.

The closing movement is secured by presence sensors that are mounted inside and outside the sliding door system. The function of the sensors is checked during each closing phase, with the presence sensors monitoring the entire passage through the door. If an object is detected during the closing movement, the sliding door opens immediately. The mains voltage used to operate the sliding door system is constantly monitored by the control system. If the mains voltage fails, the system automatically switches to battery voltage. The energy stored in the battery can still be used to move the sliding door, e.g. the door can be closed and locked. The sliding door can optionally be opened using 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 There, a sliding door system with at least one sliding door leaf is described, which can be driven by means of a drive device controlled by an electrical control device. The door system is Can be used as an escape and rescue route, as the drive device is designed in such a way that the sliding door leaf is opened when an emergency signal is received to clear an escape route and the sliding door system can be locked by a locking device at least in one operating state. An unlocking device is provided for unlocking the locking device. With this sliding door system known from the state of the art, the path is cleared for people in the event of an escape.

Another door system is from the DE 10 2010 002 870 A1 known, whereby this sliding door system also has a release for opening an escape and rescue route. The same applies to the state-of-the-art DE 10 2010 024 755 A1 , which also provides the function of an escape route door, by means of which a person can operate the door drive during fault operation in order to carry out an opening or closing cycle of the sliding door leaf from the closed position indicated by the fire protection function device.

These sliding door systems, which are known from the state of the art and which meet the required features for an escape and rescue route, are not suitable for use as fire doors/fire barriers to provide a fire barrier in buildings, for example, as is the case with mechanical fire doors. These work together with mechanical energy storage devices which, in the event of a fire alarm, close the door or sliding door and seal off the building area in such a way that it is protected against fire penetrating through.

Task

The invention therefore addresses the problem of providing a door control for an automatic door such as a sliding door, a revolving door or the like, which fulfils the function of a self-closing closure, e.g. a fire protection sliding 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 further developments emerge from the subclaims.

The additional control according to the invention initiates the closing movement immediately when a signal from the signaling device is received, e.g. in the event of a fire, regardless of the door program set on the door control. In this phase of the signal, the additional control disconnects the drive train, i.e. the motor cables or one or two drive trains are electrically disconnected from the door control of the basic control. The additional control switches over to itself so that the additional control and not the basic control of the door control is electrically connected to the drive train.

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

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, presence sensors or even by ignoring them.

If the presence sensors are ignored in the signal phase, there is a risk to people during the closing movement. This should be avoided by the additional control closing the automatic door at a low speed and with load shutdown by motor current. The low speed must be selected so that a risk can be ruled out by standards. If the closing movement takes place while evaluating the safety sensors optionally connected to the additional control, the door can be moved at normal speed. If the presence sensors are triggered in this closing phase, the door immediately stops. If the safety sensors optionally connected to the additional control are occupied for a longer period of time in this phase, the signal is ignored by the control and the door continues to close at a low speed as described above.

If the closing movement takes place without evaluating the presence sensors, the door closes only at a low speed. There is therefore no danger to people.

The automatic door then locks in the closed position using a locking mechanism that can be controlled and/or switched by the additional control system, whereby the locking mechanism prevents the automatic door from being pushed open in at least one position up to the entire area of the door. Attempts to open the door using the door control system are prevented by separating the drive units.

If there are obstacles in the passage area during an emergency closure, e.g. a fire alarm, the automatic door will drive towards the obstacle. According to a particularly advantageous embodiment of the invention, the additional control is designed in such a way that the automatic door closes cyclically and the door then tries to end the closing process.

The automatic door can only be reset or restarted using the additional control when the emergency closing signal is no longer triggered, so that manual operation of the program switch and/or other switching elements can only then be carried out.

If errors occur in the drive or in the additional control, closure is always guaranteed due to the design, so that the automatic door always closes and locks. The status of the error message can be displayed visually. The secure closure of the system is based on either redundancy being implemented on the additional control or on the additional control communicating with the basic control for redundancy.

If an obstacle is detected during the closing movement by defective safety sensors optionally connected to the additional control, such as closing area monitoring and presence sensors, the drive stops. The closing process is automatically restarted after a time delay. After, for example, five failed attempts, the drive stops at the obstacle and switches off. The number of failed attempts can be changed. However, if a fire alarm occurs, attempts to close will continue cyclically.

If the safety sensors optionally connected to the additional control are continuously triggered during the intended closing movement, this signal is indicated optically and/or acoustically by the additional control after a time x. If a signal is received from the signaling device during this time, e.g. a fire alarm, the additional control closes the door at a reduced speed. This speed ensures that there is no danger to people. The sliding door is automatically locked after reaching the closed position and the additional control switches off. Renewed operation is only possible when the user consciously starts the additional control again and the additional control does not detect any error in the system.

A critical error would be, for example, a failure or error in the main computer or a failure or error in the main drive. This situation would result in the closing movement being carried out via the main drive or the emergency drive if possible. If the safety sensors optionally connected to the additional control cannot be evaluated, the automatic door is closed at a reduced speed. This reduced speed is selected so that there is no danger to people. The automatic sliding door is locked after the closed position is reached and the additional control switches off. Renewed operation is only possible when the user consciously starts the door again and the door does not detect any error in the system.

According to the invention, it is proposed that an additional control is provided for controlling the door as a basic control, which is connected to a signaling device, for example to a fire alarm control panel or a smoke detector, and which, independently of the basic control, immediately triggers the closing movement when the signaling device receives a signal. The additional control on the automatic door is connected to a signaling device, for example to a fire alarm control panel or a smoke detector, whereby a control evaluates the signal from the signaling device via a main computer and a control computer, which, regardless of the set and programmed state of the basic control of the automatic door, causes the immediate closing movement of the door leaf or leaves via the control, in order to provide the automatic door as a fire protection door or fire barrier, unless the communication and monitoring of the Movement of the door control ensures that the additional control system closes the door. This is ensured by separating and switching the drive train from the door control.

This design means that the automatic door, which has been extended by the additional control, can also be used as a fire protection sliding door or fire protection. The automatic door does not need to be equipped with mechanical means such as a spring accumulator or a weight accumulator, for example, to create a fire barrier in the event of a fire. In the automatic door according to the invention, this is provided by the additional electronic control.

According to an advantageous embodiment of the invention, the closing movement takes place at low speed and with load switching off. The automatic door locks automatically when closed. In a further development, the additional control of the automatic door causes a cyclical closing movement in the event of an obstacle in the passage area. If the obstacle remains in the passage area, the door switches off. Opening by the door control is prevented, however.

In a further development of the invention, if the additional control fails or if there is an error in the main computer, or if there is an error in the main drive, or if the power supply fails, the automatic door closes via a redundant path to close the door. This ensures that if, for example, the power supply or the drive unit or the controls fail completely in the event of a fire, the shutdown still occurs.

According to a particularly advantageous embodiment of the invention, an error is indicated visually if the control system fails. The automatic door can only be restarted if there is no fire alarm. When the automatic door is restarted, this can only be done by manually operating the additional control system. If it is necessary to open the safety door, it is still possible to open it manually, although in the event of a fire the control system always provides a closing mechanism.

Another particularly advantageous embodiment of the invention ensures the reliability of the closure in that, via safety-relevant communication between the basic control and the additional control, part of the redundancy is on the additional control and a second part is on the basic control. This means that a closure or a fire protection closure can be achieved with little component effort. This also applies if the basic control or additional control is subject to a critical error.

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

implementation examples

The Figure 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 a motor 2 and/or a motor 3. The door control 1 comprises a basic control 4 and an additional control 5, both of which are connected to the motors 2, 3 via a switch 6. The switch 6 is in the Figure 3 and in the Figure 5 presented in more detail here.

The basic control 4 normally drives the automatic door unless the switch 6 is operated by a redundant system 7 of the additional control 5. A power supply 9, a battery 8 and a trigger 10 such as a fire alarm are connected to the redundant system 7. The redundant system 7 is operatively connected to the switch 6 and is thus connected to the motors 2, 3 and the locking mechanism 11. In addition, a closing area monitoring system 12 can be connected to the redundant system 7.

If the release 10 is activated as a result of a signal, the motors 2, 3 are separated from the basic control 4 of the door control 1 by means of the switch 6 and switched to the additional control 5 according to the invention. The additional control 5 immediately causes the closing movement of the door leaf or leaves in order to use the automatic door 1 as a fire door or as a fire barrier.

The Figure 2 shows the additional control 5 and here 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 a motor 2, 3. The door control 1 is connected to the motors 2, 3 via the switch 6 and can normally drive them unless the redundant system 7, consisting of a battery charge 13, a control computer 14 and a motor control 15, does not operate the switch 10. The system 7 consists of a main computer 16 and a control computer 14, which monitor each other and thus operate the redundant motor control 15 consisting of the motor output stage 17 and the emergency stage 18 and which operate the switch 6. The system 7 is supplied by the power supply 9 or the battery 8, so that a permanent supply is guaranteed. The trigger 10, via which the signal is received, is directly connected to the system 7 and thus to the main computer 16 and the control computer 14. An optional additional closing area monitor 12 is also connected to the system 7. The motor control 15 consists, as already mentioned, 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 is connected to the motors 2, 3 via the switch 6.

Due to the redundancy contained in the motor control 15, the motor(s) 2, 3 can still drive the motor(s) 2, 3 even if a component, for example the motor output stage 17, fails, so that a safe closure is possible.

Furthermore, the locking mechanism 11 is connected to the switch 6 so that it can be controlled by the additional control 5.

If the release 10 is activated as a result of a signal, the motors 2, 3 of the door control 1 are separated from the basic control 4 by the switch 6 and switched to the additional control 5 according to the invention. The additional control 5 will then immediately cause the closing movement of the door leaf or leaves, taking into account the closing area monitoring 12, in order to use the automatic door 1 as a fire door or as a fire barrier to ensure closure. The main computer 16 and/or the control computer 14 are controlled so that the signal for the motor output stage 17 or an emergency stage 18 is passed on to start up the motors 2, 3.

The Figure 3 shows, by way of example, the switch 6 contained in the additional control 5 according to the invention. The switch 6 consists of a voltage switch 19, a motor switch 20, a locking switch 21 and a motor control switch 22, which is operatively connected to the system 7 of the basic control 4, the motors 2, 3, the motor control 15 and the battery 8 and the locking.

The battery 8 and the power supply 9 can be switched from the system 7 to the motor control 15 via the voltage switch 19. This ensures that the motor control 15 is always supplied with voltage If the basic control 4 of the standard door control is separated from the motor(s) 2, 3 via the motor control switch 22 and the system 7, the redundantly supplied motor control 15 can drive the motors 2, 3 to close. The motor control switch 22 enables the system 7 to select one of the two or both motors 2, 3 to close the door, so that if one of the two motors 2 or 3 is defective, it is guaranteed that the door will still close.

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

The Figures 4 and 5 The embodiment described and shown behaves in such a way that when the trigger 10 is activated as a result of a signal, a closing command 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 determined that no closing is carried out by the basic control 4, the motors 2, 3 are separated from the basic control 4 of the door control 1 by means of the switch 6 and switched to the additional control 5 according to the invention. The additional control 5 immediately causes the closing movement of the door leaf or leaves in order to use the automatic door 1 as a fire door or as a fire barrier.
