Description

The present invention relates to a control device for at least one leaf of a door, window, or the like. The present invention also relates to a system comprising such a control device. Such a control device is used, for example, to receive signals from a central smoke and heat exhaust ventilation system (SHEVS) and forward them to drives and locking units of doors, windows, or the like. In the event of a fire, for instance, doors or windows should be opened to ensure proper smoke extraction or a good supply of fresh air. Since these are safety components, it is essential that the doors and windows can be reliably opened in an emergency. Therefore, it must be ensured that the locking mechanisms of any door or window designed to open will reliably unlock even in the event of a fire, allowing the operating mechanisms to open them. The applicant already markets such a control device under the name "MST 212". Figure 5 shows such a control device as a block diagram. The control device has a first connection for a supply voltage from a power supply unit and a second connection for connection to the smoke and heat exhaust ventilation system (SHEVS), which provides a supply voltage in case of fire / emergency. Furthermore, the control device has a supply voltage connection that can be connected to an interlock unit and an enable connection (designated RLS1) for activation. The voltage supplied by the SHEVS is stepped up to 24 V via a linear voltage regulator if the voltage exceeds this value. This control device serves as an interface between the smoke and heat exhaust ventilation system (SHEVS) and the components of the door to be opened, particularly the locking mechanism and the drive. Although this control device has proven itself in practice, the desire for further simplification on the one hand and increased reliability on the other remains. Furthermore, it would be desirable if the control device could be used universally for different locking mechanisms and drives (with regard to higher power output and different supply voltages). From DE10 2021 109 154 A1, a control device for electric door locking devices is known, characterized by a compact design with a single integrated component. The device includes several analog and digital inputs and outputs, a programmable processor, and an integrated or external power supply unit. The integration of all components into a single IC allows for the direct control of a variety of electrical actuators, such as door openers or motorized locks. Furthermore, universal adaptability to different locking types is provided through selectable programs and parameter sets. German patent DE10 2009 023 491 A1 relates to a safety circuit for electrical devices such as door locks, designed to ensure a safe switching state in emergencies. The circuit uses a control circuit with data inputs and a sensor to detect the actual state of a controlled circuit and compare it to a target state. If a deviation occurs, the controlled circuit is switched to the desired state without any feedback. Optocouplers are preferably used to isolate the control circuits. The solution is particularly suitable for emergency stop circuits in escape doors and can be implemented modularly as a microprocessor or integrated circuit. Against this background, the object of the present invention is to provide a control device for at least one leaf of a door, window, or the like, which enables the simple and safe use of various locking units, even in combination with different systems, for example, access control systems or emergency exit systems (ERS). In addition, the safety and flexibility of the control device are to be increased. The problem underlying the invention is solved by a control device having the following features: a first connection with two connection points for supplying a supply voltage, in particular 24 V; a second connection with two connection points for connection to a higher-level control system, in particular a smoke and heat exhaust ventilation system (SHEVS); a first supply voltage connection with two connection points for connection to a first locking unit assigned to at least one wing; a first release connection with two connection points for connection to the first locking device; a second release connection with two connection points for connection to an external release unit;a controllable switching device designed to connect one terminal of the first enable terminal to the other terminal of the first enable terminal or to a terminal of the second enable terminal; and a boost converter whose input is connected to the first terminal and the second terminal, and whose output is connected to the first supply voltage terminal, the boost converter being designed to provide a predetermined voltage, preferably 24 V, at the output. The control device according to the invention has, among other advantages, the provision of a stable output voltage for unlocking and operation. In particular, the provided boost converter ensures that a constant voltage, e.g., 24 V, is available at the output even when the voltage from the smoke and heat exhaust ventilation (SHEV) control unit (emergency power supply) drops. This enables reliable unlocking. A further advantage of the control device according to the invention is that, for example, power supplies can be connected via the various connections to provide the voltage for the locking units during normal operation (not in an emergency). Furthermore, it is also possible, for example, to connect an external DC / DC converter to reduce the supplied voltage from 24 V to 12 V, which is required by certain locking units. Finally, the control device according to the invention allows for simple and safe wiring of the components used on a single-leaf or double-leaf door, a single-leaf or double-leaf window, or the like. For example, smoke and heat exhaust ventilation (SHEV) lever drives as part of so-called supply air systems, as well as locking units required for locking the doors, power supplies for the locking units during normal operation, smoke and heat exhaust ventilation (SHEV) systems, access control systems, a SHEV control panel, and also automatic door drives for daily use can be connected to the control device according to the invention. It should be noted at this point that even if the following refers “only” to a door or a door leaf, this is not to be understood as restrictive in the context of this description, but always also includes windows, gates or the like. The problem is thus completely solved. In a preferred further training, the other connection point of the first release connection is connected to the other connection point of the second release connection. In a preferred embodiment, a voltage rectifier is provided, the two inputs of which are connected to the two terminals of the second terminal and the two outputs of which are connected to the input of the boost converter, wherein the voltage rectifier is designed to provide an output voltage with fixed polarity independent of the polarity of the input voltage. This measure has the advantage that the locking units continue to be supplied with power and a reliable reset is ensured, even if the emergency power supply is reversed when resetting the smoke and heat exhaust ventilation (SHEV) control unit after a fire. In a preferred further development, a time delay device is provided which is connected to at least one terminal point of the second terminal in order to receive an input signal, and is designed to generate a switching signal with a time delay depending on this input signal and to supply it to the switching device for switching. This measure delays the release signal from the smoke and heat exhaust ventilation (SHEV) control unit (the voltage supplied by the SHEV control unit) to the switching device, giving the locking unit's electronics time to boot up and process the release signal. Under normal operating conditions, the locking unit is powered by a mains supply, and the time delays are omitted to avoid negatively impacting ease of use. It should be noted that in the event of a fire, the locking units' power supply is taken over by the SHEV control unit's emergency power function. During this switchover, the locking units may be briefly without power. When power is restored, the locking unit's electronics may need to reboot before control signals can be processed and executed. In practice, a delay of 0.5 seconds for the time delay device has proven sufficient. Of course, the delay could also be within a range of 0.1 to 1 second. Alternatively, the delay could be adjustable, for example, within a range of 0.1 to 1 second. In a preferred embodiment, a second supply voltage connection with two connection points for connection to a second locking unit, which is assigned to a second wing, is provided; a third release connection with two connection points for connection to the second locking device; and a fourth release connection with two connection points for connection to an external release unit. The switching device is further configured to connect one connection point of the third release connection to its second connection or to a connection point of the fourth release connection. Preferably, the other connection point of the third release connection is connected to the other connection point of the fourth release connection. This measure has the advantage that the control device can also control two locking units of a double-leaf door. In a preferred embodiment, a DC-DC converter is provided, the input of which is connected to the first supply voltage terminal and the output of which can be connected to the first and / or second locking units, wherein the DC-DC converter is designed to convert the DC voltage at the input, preferably 24 V, to a lower DC voltage, preferably 12 V. This measure has the advantage that locking units operating at a lower voltage, for example 12 V, rather than 24 V, can also be connected to the control device according to the invention. In particular, the interaction between the boost converter, DC-DC converter, and time delay results in a control device with significant advantages. In a preferred further development, the controllable switching device is designed as a relay, in particular as a monostable relay. This measure has proven to be particularly advantageous in practice; in particular, the use of relays is more advantageous than electronic switching elements in this application. In a preferred further development, a housing is provided that accommodates at least the controllable switching device, the boost converter, the voltage rectifier and the time delay device. This measure has the advantage of providing a compact, easy-to-handle unit that simplifies cabling and connection to the various components. It should also be noted that the aforementioned components, such as the rectifier and time delay device, can also be used independently without the boost converter. The problem underlying the invention is also solved by a system comprising the control device according to the invention, at least one leaf of a door, window, or the like, a drive designed to open and / or close the leaf and connected to a control device, and a locking device associated with the leaf and designed to lock the door and unlock it upon receiving a release signal, wherein the release signal is provided by the control device. "Provided" in this context means that the release signal is received, for example, by the control device and passed on to the locking device, i.e., looped through. Of course, it would also be conceivable for the release signal to be generated by the control device itself, for example, upon or after receiving a control signal from an external source. The system preferably further includes a smoke and heat exhaust ventilation system (SHEVS) that provides a supply voltage to the control device in case of emergency. The door preferably has two leaves, one of which is the active leaf and the other the inactive leaf. A further preferably included drive, preferably a swing door drive, is designed to open and / or close the leaf and is connected to the control device. In such a system configuration, the control device according to the invention can be used particularly advantageously. It is understood that the features mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present invention. Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings. These show: Fig. 1 a schematic block diagram of a system according to the invention; Fig. 2A a schematic block diagram of a control device according to the invention in a first operating mode (normal case); Fig. 2B a schematic block diagram of a control device according to the invention in a second operating mode (smoke and heat exhaust ventilation case); Fig. 3 a schematic block diagram illustrating electrical connections in the normal case and in the smoke and heat exhaust ventilation case; Figs. 4A-D schematic block diagrams illustrating different system configurations; Fig. 5 a schematic block diagram of a control device according to the prior art. Figure 1 shows a system as a block diagram, labeled with reference numeral 10. This system is used in buildings to open doors, windows, or the like, for example in case of fire, so that fresh air can be supplied, e.g., by a chimney effect. Annex 10 features a door 12, which in this example consists of two leaves, namely a fixed leaf 14 and an active leaf 16. It should be noted, however, that the door 12 represents building elements such as doors, windows, or gates used in buildings to close openings. Both the fixed leaf 14 and the active leaf 16 are each assigned an operator 22 or 20, respectively, to open and, if necessary, close the respective leaf in the event of a fire. The two operators 20 and 22 are, for example, lever-operated door operators integrated into a supply air system, while the door remains freely accessible under normal circumstances. Of course, in addition to such lever-operated door operators of a supply air system, each leaf can also be assigned another operator for opening and closing, which normally opens and closes the door automatically. It is also conceivable that each leaf could be assigned a mechanical door closer that closes the door automatically after it has been manually opened. Each active and inactive leaf can be assigned an additional drive 80, 82 to open and / or close the respective leaf electrically or mechanically. The drive can, for example, be a swing door drive 82, which has an electric motor for opening and / or closing the leaf. Alternatively, the drive can also be designed as a mechanical door closer 80, which closes the door mechanically. The aforementioned drives 20, 22 are responsible for opening the leaves in an emergency, while the drives 80, 82 operate the leaves during normal operation, i.e., opening and / or closing them. To lock the two leaves 14, 16 in the closed state, so-called locking devices or locking units 24, 26 are assigned to both leaves, whereby a locking unit can be designed, for example, as a motor lock or door opener. A control device 30 is provided to control both the two drives 20, 22 and the locking units 24, 26. This control device 30, which will be explained in detail later, sends, among other things, release signals to the locking units 24, 26 via electrical connections to initiate unlocking. It also sends opening signals to the drives 20, 22 to open the respective leaves. Such an opening signal can be provided in the form of a supply voltage for the drive or as an independent start signal to start the drive. The control device 30 is further connected to a smoke and heat exhaust ventilation (SHEV) control panel 40, which takes over the emergency power supply in an emergency, for example a fire, i.e., supplies the control device 30 with a supply voltage, preferably from a battery. At the same time, this supply voltage ensures the provision of the enable signals. The control device 30 is also connected to an access control system 50, which is used to allow only authorized persons to open the doors. Typically, such an access control system 50 includes, for example, card readers or RFID readers. For clarity, these readers are not shown in Fig. 1. A switch 52 can be provided to unlock the doors. This switch is connected to the control device 30 and can thus transmit an opening signal to it. Unlocking the door then allows, for example, manual opening of the door or opening of the door by the swing door drive 82. Finally, Fig. 1 shows a power supply unit 60 that supplies a voltage, for example 24 V, to the control device 30. This voltage normally serves as the power supply for the locking units 24 and 26, as well as the control device 30. Unlike the swing door drives 82, the two drives 20 and 22 are not normally supplied with a voltage. As mentioned previously, in the event of a fire, i.e., in the event of smoke and heat exhaust ventilation (SHEV) activation, the power supply is no longer provided by the power supply unit 60 but by the SHEV control panel 40, at which point the two drives 20 and 22 are supplied with a voltage. With reference to the two figures 2A and 2B, the structure of the control device 30 is described in detail below. In Fig. 2A, the control device 30 is shown in the form of two blocks 31 and 32. It should be understood that the division into two blocks 31 and 32 is exemplary and does not mean that the physical structure is also designed in two parts. The functions provided in the two blocks 31 and 32 can also be provided in a single physical unit. Block 31, which is designed, for example, as a circuit board, has several connections, which can be in the form of connection contacts or terminals. A first connection 33 has two connection points 33.1 and 33.2, to which a supply voltage can be applied. For example, the power supply 60 can be connected to the two connection points 33.1 and 33.2. Block 31 also has a second connection 34 with two connection points 34.1 and 34.2. This connection 34 can be connected to the smoke and heat exhaust ventilation (SHEV) control unit 40. In other words, an emergency voltage is present at this connection 34. As briefly mentioned earlier, this emergency voltage can change its polarity when the emergency is reset. Block 31 also has two supply voltage terminals 35 and 36, each with two connection points 35.1 and 35.2, and 36.1 and 36.2, respectively. The first supply voltage terminal 35 can be connected to the first locking unit 26 of the active leaf 16, while the second supply voltage terminal 36 is then connected to the second locking unit 24. The locking units receive the voltage required for locking and unlocking via these supply voltage terminals. Figure 2A shows a DC / DC converter 38, which is connected between the first supply voltage terminal 35 and the locking unit 26. The converter 38 can be provided if the locking unit 26 requires a lower voltage, for example 12 V, and cannot operate with the higher voltage of 24 V applied to the supply voltage terminal 35. Block 31 also has a third connection 39, which also includes two connection points 39.1 and 39.2. The two drives 20 and 22, for example, can be connected to this connection 39. Block 31 includes a boost converter 42, the input of which is connected to the two terminals of the first terminal 33 and the second terminal 34. In other words, the boost converter 42 receives the voltage applied to terminal 33 and terminal 34. A rectifier 44 is also provided in the connection between the two terminals 34.1 and 34.2 of the second terminal, which ensures that no polarity change occurs at its output when the polarity at the second terminal 34 changes. The output of the boost converter 42 is connected to the two supply voltage terminals 35,36, so that the voltage provided by the boost converter 42 can be transferred to the two locking units. The function of the boost converter 42 is, in particular, to condition the voltage supplied by the smoke and heat exhaust ventilation (SHEV) control unit 40 in the event of a fire, specifically to bring it up to the desired voltage value, for example, 24 V. This conditioning of the voltage is necessary because the emergency power supply of the SHEV control unit delivers between 18 V and 28 V, depending on the battery level. However, a voltage of 24 V ±15% is required to unlock the locking mechanisms, so without this conditioning, unlocking might not occur. The boost converter 42 is therefore designed to convert a voltage in the range of, for example, 11 V to 28 V to a voltage of approximately 24 V ±15%. Finally, block 31 also includes a time delay device 46, the input of which is connected to the second terminal 34. The output of the time delay device 46 is connected to a switching device 48, which is part of the second block 32. The function of the time-delay device 46 is to transmit the voltage signal at terminal 34 to the switching device 48 (to trigger a switching operation) with a time delay. In other words, in the event of a fire, when the smoke and heat exhaust ventilation (SHEV) control panel applies a voltage to terminal 34, this voltage is transmitted with a time delay to the switching device 48. The voltage applied to terminal 34 in the event of a fire therefore does not cause the switching device 48 to switch immediately. Rather, the switching occurs with a time delay, for example, with a delay of 0.1–1 second, preferably 0.5 seconds. Block 32 has several enable terminals 54, 56, 58, and 62, each with two connection points. The two connection points of each terminal are labeled RLS 1 and RLS 2. As shown in the figure, the two connection points RLS 2 of terminals 54 and 56 are connected to each other. The same applies to the two connection points RLS 2 of terminals 58 and 62. The two connection points RLS 1 of the two terminals 54 and 56, as well as of the two terminals 58 and 62, can be connected to each other via the switching device 48. In the case shown in Fig. 2A, the connection points RLS1 of the two terminals 54 and 56, as well as of the terminals 58 and 62, are connected to each other. The switching device 48, which is preferably designed as a monostable relay, is thus in a first switching state, which is reached when using a relay in the de-energized state. Figure 2A shows that terminals 54 and 58 are connected to locking units 24 and 26, respectively. Both locking units also have release terminals, each with two connection points, RLS1 and RLS2. The other two terminals, 56 and 62, are each connected to external release switches 64 and 66. These two release switches represent switches that connect the two connection points RLS1 and RLS2. Such switches can be found, for example, in a surface-mounted push button, such as switch 52, or in more complex access control systems 50, or, for example, in a door operator. Closing a release switch 64 or 66 generates a release signal that is sent to the locking unit 24 or 26, respectively, and causes it to unlock. In the case shown in Fig. 2A, for example, the locking unit 26 of the swing leaf 16 can be unlocked by pressing the switch 52, so that the door can be opened either manually or via a drive. Figure 3 shows in detail the case shown in Figure 2A, which can be described as the normal case, with regard to the electrical connections. It is clearly visible that the respective connection points RLS 1 and RLS 2 of terminals 54 and 58 are connected to those of terminals 56 and 62 via the switching device 48. If a positive potential supplied by the supply voltage is present at connection point RLS 2 of a locking unit 24 or 26, this potential is always applied to connection point RLS 1 of the locking units 24 and 26 whenever one of the release switches 64 or 66 is pressed. In addition to this normal case, there is also the previously described fire or smoke and heat exhaust ventilation (SHEV) scenario, in which the power supply is no longer provided by the power supply unit 60 but by the SHEV control unit 40. This scenario is illustrated in Fig. 2B. It can be seen that the switching device 48 is brought into a second switching state by a voltage supplied by the time-delay device 46, in which the two connection points RLS1 and RLS2 of the two terminals 54 and 58 are connected to each other. In other words, the enabling switches 64 and 66 can no longer have any effect, since the connection points RLS1 of the two enabling switches 64 and 66 are no longer connected to the other two connection points RLS1 of terminals 54 and 58. Figure 3 illustrates this case, referred to as the smoke and heat exhaust ventilation (SHEV) case. It shows that the potential at connection point RLS2 of the locking units 24, 26 is routed via the switching device 48 to the release connection point RLS1 of the locking units 24, 26. In other words, switching the switching device 48 from the first switching state to the second switching state generates a release signal, just as the two release switches 64, 66 did previously to unlock the locking units. Due to the time delay device 46, the switching signal for the shutdown device 48 is transmitted with a time delay, so that the supply voltage provided by the smoke and heat exhaust ventilation (SHEV) control unit is already present at the locking units 24 and 26 before the switching device 48 is activated. This gives the two locking units time to reboot if they were previously switched off by disconnecting the supply voltage via the power supply unit 60. This time delay device 46 thus ensures that the switching of the switching device 48 is reliably recognized as an activation signal by the locking units 24 and 26. Otherwise, opening the door would not be possible. The following describes four different scenarios for how plant 10 can be constructed. In the scenario shown in Fig. 4A, the door 12 is provided with two leaves 14, 16, each leaf 14, 16 being assigned a folding lever drive 22, 20 for opening. A door closer 80 is provided for each leaf to close it, for example, mechanically. The two locking units 26, 24 operate with a 24 V supply voltage and have the previously mentioned release connection points RLS1 and RLS2. Both locking units 24, 26 are connected to the control device 30. Figure 4A further shows that the smoke and heat exhaust ventilation (SHEV) control unit 40 supplies a voltage to the two connection points 34.1 and 34.2 of the control device 30. This voltage is passed on to the drives, in particular the lever drives 20 and 22. In other words, in the event of a fire, when the SHEV control unit transmits this voltage to the connection points 34.1 and 34.2, the lever drives 20 and 22 are also supplied with voltage and then open the doors. At the same time, as explained previously, the locking units 24 and 26 are also activated to unlock the doors. In the scenario shown in Fig. 4A, no external power supply 60 is provided. In other words, the doors can only be opened in the event of a fire, since only the smoke and heat exhaust ventilation control unit 40 supplies the required voltage for the lever actuators 20, 22. The scenario shown in Fig. 4B includes a power supply 60 that transmits a supply voltage to the control device 30. Furthermore, an enabling switch 64 is provided, which can be used to unlock at least the gate leaf 16 and then open it manually. The appropriate supply voltage can be transmitted to the locking units 26, which operate at 12 V, via the power supply 60 and the voltage converter 38. The second locking unit 24 operates at 24 V, so a voltage converter 38 is not required here, as the control device 30 can directly provide this 24 V. The operation of this system 10 corresponds to that described with reference to Figures 2A, 2B, and 3. Here too, in the event of a fire, the switching device in the control unit 30 is switched so that the release switch 64 no longer functions and the two locking units 24 and 26 receive a release signal. The folding lever actuators 20 and 22 are then actuated via the voltage supplied by the smoke and heat exhaust ventilation (SHEV) control unit. In the scenario shown in Fig. 4C, a power supply 60 is again provided, which in this case supplies 24 V to the control device 30. Additionally, each of the two door leaves 14, 16 has a swing door drive 82, with which the two door leaves 14, 16 can be opened and / or closed independently of the lever drives 20, 22. The two swing door drives 82 are enabled via enable signals at connection points RLS1 and RLS2. Finally, Fig. 4D shows another scenario, in which, in addition to a power supply 60, an access control system 50 and a remote access control (RAC) system 51 are also provided. In addition to the two locking units 24, 26, each of the two door leaves 14, 16 is assigned locking elements 84, which are, for example, in the form of holding magnets. These two locking elements 84 are connected to the RAC system 51. As long as they are supplied with a 24 V voltage via the RAC system, these locking elements 84 exert a holding force sufficient to keep the doors 14, 16 securely in their closed position. The rotary actuators 82, which are also provided, can be released both via the control device 30 and via the RAC system 51. Overall, it is evident that the control device 30, with its various connections, allows for simple and flexible wiring. The electrical components provided in the two blocks 31 and 32 supply the required voltages and enable signals, thus ensuring safe unlocking and opening of the doors in the event of a fire. Figures 4A to 4D above show that the control device 30 according to the invention can be used in different system scenarios, regardless of whether, for example, the locking units 24 and 26 operate at 12V or 24V.
