Description

The invention relates to a control device for electric locking devices of a door according to the features of the preamble of claim 1.

In practice, there is often a need to electronically control tumblers on a door or locking devices on a door. For example, door openers or locks should be provided with sensors, or the locking elements of locks or door openers should be electronically controllable from different sources or by means of digital bus systems.

From the DE 10 2011 121 702 C5 an electronic control device for operating an electric door opener, which has an electromagnet, is known. In addition to a microprocessor, the electrical control device includes a number of electronic components in order to supply a door opener with pulsed voltage, and thus to improve shaking of the door opener when there is a high initial load or when there is magnetic remanence.

the DE 10 2006 001 078 A1 shows a door opener system for authorization-dependent access control systems on a door. This system also includes several electronic components to control a door opener accordingly.

The invention is based on the object of providing a control device for electric locking devices of a door, which can be used in a variety of ways, has a compact design and is designed in particular for controlling different electric locking devices.

According to the invention, this object is achieved by a control device for electric locking devices of a door with the features of claim 1 .

• - zumindest einen analogen und/oder digitalen Eingang zum Anschluss eines Sensors oder Schalters und
• - zumindest einen analogen Ausgang und/oder digitalen Ausgang zur Ansteuerung einer Anzeige oder eines Eingangs einer weiteren Schaltung oder einer Schnittstelle,
• - zumindest einen analogen Leistungsausgang und/oder digitalen Leistungsausgang zum Ansteuern eines Aktors oder eines Elektromagneten oder eines Motors,
• - einen programmierbaren Rechenkern, vorzugsweise einen Prozessor, und
• - einen elektronisch beschreibbaren Speicher.

According to the invention, a control device for electrical locking devices of a door, preferably door openers and/or locks or tumblers, is proposed, wherein the control device can be looped into a power supply line of such an electronic locking device or can be connected to a power supply line or control line of an electrical locking device of a door and at least the following electronic ones Components includes:

• - At least one analogue and/or digital input for connecting a sensor or switch and
• - at least one analog output and/or digital output for controlling a display or an input of a further circuit or an interface,
• - at least one analog power output and/or digital power output for controlling an actuator or an electromagnet or a motor,
• - a programmable computing core, preferably a processor, and
• - an electronically writable memory.

It is essential that the electronic components are all integrated into a single integrated module and the at least one analog power output and/or the at least one digital power output directly controls and/or switches and/or drives an actuator or motor or electromagnet.

This enables a very compact design, since the required electronic components are combined in a single integrated module (IC) and therefore only require a very small amount of space. It is also possible to optimize the electronic efficiency, i.e. the efficiency of the components, since the power requirements of the components can be better optimized in a single integrated module. By providing load outputs or power outputs which directly control and/or switch and/or drive an actuator or motor or electromagnet, the circuit design is further simplified. As a result, external driver modules can be omitted and relatively power-hungry consumers or inductive loads such as motors, in particular stepper motors, or holding magnets or lifting magnets can be connected directly to the IC and controlled and supplied by it.

In particular, a door is understood to mean a single-leaf door or a multi-leaf door, which can be designed, for example, as a revolving door or as a sliding door or as a swinging door.

In particular, locking devices of a door are understood to mean electrically controllable components arranged on a door or in cooperation with a door, which can lock or release the door in the closed position and/or an open position.

In particular, door openers are understood to mean electrically controllable door openers that release or lock a door opener latch by means of an electrically switchable actuator by applying an electrical voltage.

Locks or door locks are preferably understood to mean all types of locks in or on a door. For example, built-on locks or mortise locks or multiple locks or panic locks and the like.

In particular, tumblers are understood to mean devices for locking a door for escape routes and/or fire protection doors, which can be switched electrically. For example holding magnets or escape door openers or locking devices or the like.

The control device can preferably be designed to control a single locking device. Alternatively, the control device can be designed to control two or more locking devices, for example a door lock and a door opener.

For example, a power supply unit can be provided, which can be connected to a power supply line or control line of an electrical locking device of a door and supplies electrical energy to the electronic components, preferably all electronic components of the integrated module. As a result, the circuit complexity can be further reduced since all consumers and the controller can be supplied with electrical energy via one and the same power supply unit.

In particular, it can be provided that the power supply unit also supplies power to at least one connected actuator or motor or electromagnet of an electrical locking device of a door via the integrated module. A plurality of connected actuators and/or motors and/or electromagnets of an electrical locking device of a door can preferably also be supplied with power by the power supply unit via the integrated module. This means that there is no need for a separate power supply for the connected components, since they are supplied with power via the integrated module.

For example, it can be provided that the power supply unit is provided as a discrete unit. The power supply unit can be embodied as a module or consist of several discrete components and be embodied next to the integrated component.

In a preferred configuration, it can be provided that the power supply unit is designed to be integrated in the single integrated module. This further reduces the circuit complexity.

Provision can be made for protective devices, for example with diodes, Z diodes or Transil diodes and/or correspondingly connected transistors or FETs (field effect transistors), to protect against overvoltages or to protect against reverse polarity. As a result, the integrated component can be protected against damage caused by overvoltages. These protection devices can be embodied as discrete protection devices or as protection devices integrated into the integrated chip.

In one embodiment it can be provided that the integrated module is arranged on a printed circuit board, that the control device has only a single printed circuit board and the integrated module is arranged on this printed circuit board. In an exemplary embodiment, it can also be provided that no further active components, preferably transistors or FETs, are arranged on the printed circuit board in addition to the integrated component and components for safeguarding the power supply. This makes it possible to achieve a particularly compact design. The current requirement can also be optimized since no further active components are required which would also consume electronic current. In particular, it is preferably also provided that components such as pull-up or pull-down resistors at the inputs and/or at the outputs are designed to be integrated in the single integrated module. It is also conceivable under the inventive concept that large capacitances and/or inductances and/or load resistances are arranged on the printed circuit board in addition to the single integrated component. Protective elements such as transil diodes can also be additionally arranged on the printed circuit board. Furthermore, connecting elements such as plug connectors and/or screw connectors and/or solder connectors can be arranged on the printed circuit board in order to connect the printed circuit board, for example, to external cable connections or to other components of an electrical locking device. The printed circuit board can be designed as a single layer or multi-layer printed circuit board.

In a preferred embodiment it can be provided that the power supply unit supplies the electronic components, preferably all electronic components of the integrated module, with electrical energy. This enables a particularly simple structure, since with different power requirements of the electronic components, they all have a single power supply supply unit, which is integrated in the integrated module, can be supplied with power. Even with different current and/or voltage requirements, provision is made for the power supply unit to be able to take over the supply of electrical energy. In particular, the integrated module and/or the power supply unit has a single power supply connection.

It can advantageously be provided that the power supply unit has a rectifier and supplies the integrated module or the electronic components of the integrated module with power, regardless of whether the control device and/or the power supply unit is connected to a DC voltage line or to an AC voltage line. The operation of the control device is therefore independent of whether DC voltage or AC voltage is provided for supplying an electrical locking device.

In one configuration, it can advantageously be provided that the power supply unit has a step-up and/or step-down regulator (step-up and/or step-down converter) and obtains the power supply for the electronic components of the integrated module from a DC voltage line or from an AC voltage line, whose voltage can be below or above the required supply voltage of the integrated module or the electronic components of the integrated module. The control device can be connected to a line via the outward regulator or step-up converter or the downward regulator or step-down converter, regardless of its voltage level. It is thus possible to use different voltage lines to supply the control device. For example, it can be provided that the control device or the input of the power supply unit can be connected to a DC voltage line with a voltage between 3.3 volts and 48 volts, or to an AC voltage line with a voltage between 3.3 volts and 48 volts.

For example, the power supply unit can have a voltage converter and provide at least two different voltages for supplying the processor or the programmable computing core and for supplying the at least one analog output or digital output or the at least one analog power output and/or digital power output. As a result, the processor or the programmable computing core can be operated with a low voltage and with low power loss. At the same time, consumers connected via the load outputs, such as motors or electromagnets, can be subjected to a higher voltage in order to achieve higher outputs.

In order to ensure universal connectivity, one embodiment can provide for the single integrated module to have an analog/digital converter as a further integrated electronic component, to which the at least one analog input is connected, preferably the at least one analog input can be connected directly to an input voltage in the range from 1 volt to 48 volts. It can of course also be provided that a plurality of analog/digital converters are provided for a plurality of analog inputs or that an analog/digital converter is provided which scans a plurality of inputs in rapid succession. In particular, it can be provided that the integrated module has a number of analog and/or digital inputs, for example up to 8 or 12 or 16 analog and/or digital inputs. In particular, the inputs of the integrated module, or some of the inputs of the integrated module, can be reprogrammed or defined as analog or digital inputs by software and/or by parameters.

In an advantageous embodiment, it can be provided that the single integrated module has a wired and/or serial bus interface, in particular a CAN bus interface, as a further integrated electronic component. This makes it possible to digitally control the control device for electronic locking devices in a simple manner via a bus system, for example a field bus system, in particular a CAN bus or a Hi-O bus.

In an advantageous embodiment it can be provided that the single integrated module has a transceiver as a further integrated electronic component, in particular a transceiver designed as a Bluetooth interface or a transceiver designed as a ZigBee interface or a transceiver designed as a wireless LAN interface. This makes it possible for the control device to be controlled and/or programmed and/or parameterized wirelessly. It is just as conceivable that the control device communicates wirelessly with other components of the door control and/or mobile devices and/or transponders, for example in order to implement access control.

In a preferred embodiment, it can be provided that the electronically writable memory is an electronically writable working memory, in particular RAM Has memory, and/or has a protected electronically writable program memory and/or an application memory, in particular flash memory. It can preferably be provided that several executable programs and/or parameter sets for the programmable computing core are stored in the electronically writable memory, in particular in the application memory, with one of these programs and/or one of these parameter sets for controlling a type or a type family of electrical Locking devices of a door is formed, and wherein one of these programs and / or one of these parameter sets can be selected by means of switches or by configuring the programmable processor core in order to control a specific type or a specific type family of electric locking devices of a door.

In one configuration, the electronically writable memory can include a non-volatile memory. Data such as error messages or permanently valid parameters can be stored in the non-volatile memory. The non-volatile memory can also be used for documentation for service purposes, for example by storing a switch-on time and/or operating time and/or maintenance work carried out in the non-volatile memory.

In particular, it can be provided that several executable programs and/or parameter sets for the programmable computing core are stored in the electronically writable memory, in particular in the application memory, one of these programs and/or these parameter sets for controlling a type or a type family of electrical locking devices of a door, and wherein the programmable processor core is designed to recognize a connected type or a connected type family of electrical locking devices of a door in order to program and/or the appropriate program for the connected type or for the connected type family of electrical locking devices of a door Select parameter set automatically.

A specific type of electrical locking device is understood to mean, for example, a special door lock or a special door opener. The program and/or parameter set for controlling this type is used to determine which outputs or which inputs of the control device are connected in order to control this type, as well as what power requirement, in particular what voltage level the respective type requires and what type of actuators and/or sensors are usually present. By means of the parameter sets for the special type of locking device, for example, voltage ranges and/or current ranges and/or temperature ranges can be defined within which the type of electrical locking device for a door is usually to be operated. A family of types of electrical locking devices for a door can, for example, comprise a number of individual types of door opener or door lock, which differ mechanically in their detailed configurations but can be controlled electrically together.

In an advantageous embodiment it can be provided that the programmable computing core or processor determines a connected type or connected type family by measuring a resistance of the connecting line and/or by reading out an identifier. For example, when a voltage is applied, the processor or the programmable computing core can automatically read an identifier from the connected electrical locking device and can use this identifier to selectively select a specific program or a specific set of parameters.

In an advantageous embodiment, it can be provided that at least one of the analog and/or digital outputs is designed as a load output in such a way that it can drive inductive loads and/or ohmic loads and/or capacitive loads. Preferably in the range between 0 mA and 50 mA, preferably in the range between 0 mA and 500 mA, most preferably in the range between 0 mA and 200 mA. As a result, even current-intensive consumers, such as motors and/or actuators and/or holding magnets, can be controlled directly by the control device without additional drivers and/or output stages being required.

In an advantageous embodiment it can be provided that the power supply unit supplies the load output(s) with power. This further simplifies the construction, since no additional power supply is required even when power-hungry consumers such as motors or stepping motors or electromagnets are connected.

In particular, it can be provided that the load outputs are designed as PWM outputs in order to drive a coil or a motor or a stepping motor or a display directly, preferably with a selectable voltage, in particular with a selectable voltage in the range between 6 V and 48 V head for. By designing the load outputs as pulse width modulation outputs, the Pro processor or computer core, the required output voltage can be set at the respective load output. It is thus possible, independently of the input voltage of the control device or the line to which the control device is connected, to operate loads with a voltage level that differs therefrom. For example, 6 V consumers, ie consumers with a lower voltage level, but also consumers with, for example, 24 V, ie consumers with a higher voltage level, can be connected to a 12 V line in this way. For this purpose, it is preferably provided that the power supply unit has an integrated step-up or step-down controller in order to provide the required voltage level and by controlling the PWM output that the voltage level required for a specific current requirement of the consumer is set.

In order to dissipate the waste heat generated in the integrated module, it can be provided that the circuit board has a cooling surface or several cooling surfaces for the integrated module and/or the power outputs and the integrated module and/or the power outputs are connected to the cooling surface or the cooling surfaces, to dissipate waste heat via these cooling surfaces.

For example, a copper surface of correspondingly large dimensions can serve as the cooling surface. For example, a cooling surface can be designed as a broadened strip conductor that is electrically and thermally conductively connected to a power output.

The printed circuit board can preferably have a thermally conductive core, in particular an aluminum core, or be mounted on an aluminum plate. In order to dissipate the waste heat from the integrated module, provision can be made for waste heat to be routed from the integrated module to the thermally conductive core and/or the aluminum plate via thermal vias.

An application of the control device according to the invention according to one of the examples described above provides that it be used in conjunction with an electric door opener for locking a door (electric door opener for locking or releasing a door with a door opener housing in which a door opener latch that can be released or locked via an electric actuator is movable is mounted) is used, in which it is provided that a control device according to one of the preceding claims is accommodated in the door opener housing. Thus, an electric door opener with an integrated control device is provided, which is suitable for different applications. Due to the high level of integration of the control device, it is possible to integrate it completely into the existing housing of an electric door opener without having to increase the size of the door opener. This makes it easy to upgrade or retrofit existing systems.

In order to ensure good cooling, it can be provided that the integrated module is thermally conductively connected to the door opener housing. For example, the housing of the integrated module can rest directly on the door opener housing or be connected to the door opener housing via a good heat conductor, for example an aluminum block, a copper block or a thermally conductive mat.

A further preferred application of the control device according to the invention can provide that a door lock, in particular a motor lock, for locking or releasing a door has a lock case in which a sensor and/or a locking element that can be moved via an electric actuator is movably mounted. It is essential that a control device according to one of the preceding claims is accommodated in the lock case.

In order to ensure good cooling here as well, it can be provided that the integrated module is thermally conductively connected to the lock case. For example, the housing of the integrated module can rest directly on the lock case or be connected to the lock case via a good heat conductor, for example an aluminum block or a copper block.

A further possibility of the control device according to the invention provides a method for retrofitting an electric locking device (method for upgrading an electric locking device, in particular a door opener or a door lock arranged on a door). What is essential here is that a control device according to one of the preceding claims is connected to a power supply line of the electrical locking device and to a sensor and/or an actuator of the electrical locking device, or that a power supply line of the electrical locking device is separated and a control device according to one of the preceding claims in the power supply line is looped in. In this way, existing systems can easily be retrofitted with a control device according to the invention.

Furthermore, an application of the inventive control device includes a method for expanding a locking device of a door, with a digital BUS interface, in particular a door opener or a door lock arranged on a door. What is essential here is that a control device according to one of the preceding claims is looped into a power supply line or a control line of the electrical locking device or is connected to it. In this way, existing systems can easily be expanded to include a digital bus interface and/or a wireless interface, without the existing systems having to be extensively modified.

The electrical locking components of the door include a door lock 81 as well as a door opener 82 and a holding magnet 83. The output line 4 includes several wires corresponding to the connecting wires that are required to control the door lock 81 or the door opener 82 or the holding magnet 83. The output line 4, which leads to the door lock 81, has a flexible cable transition 41 in order to lead it over the door frame 91 to the movably mounted door leaf 9. In other configurations, the control device 1 can be designed to control a single locking device, for example a door opener 82 or a door lock 81 or a tumbler 83 .

The door lock 81 has a door handle 811 via which it is possible to unlock the door lock 81 manually in order to open the door leaf 9 .

The door opener 82 is arranged sunk on the door frame 91 and interacts with a latch bolt 821 or a catch 821 to lock the door leaf 9 in a closed position. The retaining magnet 83 is arranged in an engaging manner between the door frame and the movable door leaf and is intended to form an additional locking point which locks the door leaf 9 in its closed position and where there is authorization or in the event of an alarm, for example a fire alarm or any other event for anyone to give freely. Otherwise, the holding magnet 83 enables the door leaf to be opened if authorization is present, for example in the form of a key or a transponder that is read in via the control device 1 .

In the 1 it is provided that the electrical control device controls several electrical locking devices at the same time.

Apart from that, it can also be provided that each electric locking device is controlled by means of its own control device 1, or that the control device 1 controls two locking devices.

the 2 shows an embodiment of the control device 1 according to the invention for controlling a door opener 82. The door opener 82 has a door opener housing in which a door opener latch 822 is movably mounted. An electrical actuator is arranged inside the door opener housing and interacts with the door opener latch 822 in such a way that the door opener latch 822 can be switched, released and/or locked via the electrical actuator. The control device 1 is arranged inside the door opener housing. The control device 1 has a printed circuit board 5 which is completely surrounded by the housing of the door opener 82 . The only integrated component 2 of the control device 1 is arranged on the printed circuit board 5 . The control device 1 is connected with its output to the actuator of the door opener. The power supply line 7 of the control device 1 is connected to the connection block of the door opener 82 and tied to the installation line of the door opener 82 with this. In the 2 the connection block of the door opener 82 is not shown. It can be a connection block with screwable connection terminals or with clampable wire connections.

The control device 1 is arranged with its printed circuit board 5 completely within the lock case of the door lock 81 and is surrounded on all sides by the lock case. The door lock 81 can be actuated manually via a door handle 811 . Inside the door lock 81, a lock bolt 812 and a lock latch 813 are movably mounted as locking elements. The lock bolt and/or the lock latch can be moved via a digital actuator. For example, a motor is provided which moves the lock bolt 812 into the closed position, ie into a position protruding from the lock housing, or pulls the lock bolt 812 back into the lock housing. The output of the control device 1 is connected to the actuator of the lock 81, not shown in the figure, in order to control it. Sensors can also be arranged in the lock case of door lock 81, for example a closed position sensor for detecting the closed position of the door and a bolt sensor for detecting the locked or open state of the door lock and/or a handle sensor for detecting a position of the follower. The control device can be connected to the sensors and queries them via their analog or digital inputs.

In the 4 a schematic overview of an embodiment of the control device according to the invention is shown. The control device 1 has a circuit board 5 on which the single integrated module 2 is arranged with all the electronic components of the control device 1 in the integrated power supply unit 12a. A power supply connection 7 connects the integrated module 2 and the power supply unit 12a arranged in the integrated module 2 to a power supply line and/or control line 7 .

the 5 is a schematic overview of a further embodiment of the control device according to the invention. Unlike that 4 Here the power supply unit 12b is designed as a discrete power supply unit 12b, ie not integrated in the integrated module 2. The power supply unit 12b is connected to a power supply line via the power supply connector 7 . The power supply unit 12b has a voltage converter and makes two different voltages available at its output. The first voltage 121 is provided to supply the outputs 14, 18 of the integrated module 2 via a separate connection. The voltage level of the voltage 121 is above the voltage level of the second voltage 122, which is provided via a dedicated connection 122 to supply the electrical components, such as the processor 11, memory 19, 111, 112, 113. For example, the first voltage can be 12V or 18V or 24V. The second voltage 122 can be 3.3V or 5V.

At the in 4 In the exemplary embodiment shown, the integrated power supply unit 12a supplies the outputs 14, 18 and the electrical components such as processor 11 and memory 19 via internal lines. Otherwise, the embodiments agree 4 and 5 match.

A writable memory 19 is arranged in the integrated module 2 in addition to a programmable computing core 11 or processor 11 . The writable memory has an application memory 111 , a main memory 112 and a flash memory 113 . In the application memory 111, one or more control programs and/or sets of parameters can be stored for a specific application or for the type or type family of electric locking devices of a door that is controlled in each case. The working memory 112 is designed for the temporary storage of working values that the processor 11 needs when executing an application program. Further program modules and/or drivers and/or an operating system for operating the processor 11 can be stored in the flash memory 113 .

Furthermore, the integrated module 2 includes a programming interface 15, via which the programs and/or application modules and/or parameter sets stored in the electronic memory 19 can be changed and/or stored. A computer or laptop, for example, can be connected to the programming interface 15 . In particular in order to test and/or program and/or initialize the electronic control device 1 .

Furthermore, a serial interface 16 is arranged in the integrated module 2 in order to connect the control device 1 to a CAN bus, for example. A transceiver 17 is also integrated in the integrated module 2 in order to connect the module to other devices and/or a wireless network via a wireless bidirectional interface, preferably a low-energy Bluetooth interface.

Furthermore, the integrated module 2 has a number of inputs which are connected to the processor 11 via an input unit 13 . For example, sensors such as door contacts, bolt contacts, closed position sensors and/or analog sensors such as position sensors or temperature sensors can be connected to the inputs. The inputs of the analog sensors are routed via an analog-to-digital converter in order to translate their analog values into digital values that the processor 11 can read.

Furthermore, the control device 1 or the integrated module 2 has digital outputs 14 in order to control further components or, for example, to control LEDs. Furthermore, 2 load outputs 18 are integrated in the integrated module. The load outputs 18 are designed in such a way that these coils or double coils or motors or stepper motors or holding magnets can be controlled directly. The load outputs are in the form of PWM (pulse width modulation outputs) and, in addition to a high load of up to 1 A or preferably up to 2 A, can also supply a voltage that can be set via a corresponding pulse width modulation.

The power supply unit 12a, 12b is designed to supply all electrical components integrated in the module 2 with power. Furthermore, the power supply unit 12a, 12b is designed to also supply the load outputs 18 and the loads connected to the load outputs with power. For this purpose, the power supply unit 12a, 12b has a combined step-up and step-down converter in order to provide a wide-range input with regard to the voltage supply.

The power supply unit 12a, 12b is designed to cover a voltage range of 3.3 V to 50 V, preferably 6 V to 48 V, and to supply the components of the integrated module 2 and the loads connected to the load outputs 18 with the corresponding voltage. For example, the power supply unit 12a, 12b is designed in such a way that when the supply voltage of 6 V is connected to the power supply unit, the loads connected to the load outputs can be supplied with an operating voltage of 12 V or 24 V. In this case, the power supply unit 12a, 12b converts the input voltage from 6 V to the corresponding output voltage via the step-up regulator.

The power supply unit 12a, 12b is just as well designed in such a way that, given a high input voltage, for example 48 V, it can supply consumers with 12 V that are connected to the load outputs. In this case, the power supply unit 12a, 12b converts the high connected supply voltage to the lower operating voltage of 12 V or to 24 V by means of a step-down regulator.

In order to adapt the control device 1 to a specific electrical locking device, for example to a specific door opener or a specific door lock, it is provided that corresponding switches and/or jumpers are arranged on the printed circuit board 5, via which a specific type of locking device, i.e. a specific Door opener or a specific door lock is adjustable. Based on this jumper setting, the processor 11 retrieves the corresponding application program and/or the corresponding parameter set for controlling the specific door opener type or lock type from the application memory in order to control it correctly. This makes it possible to use the control device 1 according to the invention to control a wide variety of types of locking devices of a door without having to change the hardware of the control device.

On the one hand, the electrical locking devices can be connected to the load outputs 18 for driving motors or coils via an output line 4, or via the digital outputs 14, to control simple LEDs or a status display. Corresponding sensors of the electrical locking devices can be connected to the control device via the inputs 13 so that the sensors can be used, for example, to read an operating state of the connected door opener or the connected door lock from the control device 1 is. The control device 1 is thus able, for example via the CAN interface 16, to report an operating state of the connected door opener or an operating state of the connected door lock to a higher-level control system.
