description
CONTROL DEVICE FOR LIGHT SOURCES WITH MICROPROCESSOR AND PROGRAMMING INTERFACE
The invention relates to a largely and essentially freely configurable ballast for at least one lamp and in particular an LED by a user.
For this purpose, the ballast has a programmable microprocessor, which has a relatively large computing power and in different ways, i. can communicate with the aid of a large number of interfaces. A DALI, SPI, DSI, WLAN, Bluetooth, LAN and / or USB interface can be provided for this purpose.
Both sensors and signal generators can be connected to the ballast and the microprocessor is connected to the interfaces in order, for example, to evaluate sensor signals and signals from signal generators. Based on incoming signals from sensors and / or signal transmitters, or signals incoming via the interfaces, the microprocessor can then, for example, change the operating properties of the ballast and thus e.g. affect the light emission or other functionalities of the ballast. Communication with external communication partners is possible, for example, via LAN, Bluetooth, USB, DALI, WLAN, ...
In particular, the ballast has a programming interface via which application software can be transmitted to a memory unit provided in the ballast. This is a software and / or software component that can be executed and run by the microprocessor and that can be part of firmware and / or the operating system or be executed as a result. The application software is then executed, among other things, by the microprocessor. In particular, the operating system manages a memory area which can be subdivided into a user area (“user space”) and an operating system core area (“kernel space”). This division is used to allow protection of parts of the memory area. The operating system kernel area is then reserved for executing the operating system kernel, while the user area is provided for executing application software and / or drivers for interfaces and / or devices connected to the microprocessor. The memory area can be part of a memory provided by the memory unit.
By transferring the application software in the memory of the ballast and preferably the user area, a user can influence the way and determine how the ballast behaves or how, for example, signals from sensors or signal generators are evaluated and to control the at least a lamp can be used. It can also be configured how an evaluation for the control of components connected to the ballast via the interfaces is processed.
In particular, the evaluation and processing of input signals can be configured or changed by means of the application software and, in particular, a lighting control can be defined as a function of detected signals.
[0007] The invention thus provides a ballast and a lamp according to the independent claims. Developments of the invention are the subject of the dependent claims.
In a first aspect, a ballast for lighting means is provided, in particular LEDs, comprising a microprocessor with at least one memory unit and a board with at least one edge, on which at least one programming interface accessible from outside the ballast and at least one signaling interface, which preferably also is accessible from outside the ballast, are attached, the microprocessor being configurable via the programming interface, and at least one application software executable by the microprocessor being transferable to the at least one storage unit via the programming interface, the application software being
software influences at least one of the following functionalities of the ballast: interaction with sensors, evaluation of signals transmitted to the signaling interface, control of the light source, activation / deactivation of interfaces of the ballast, activation / deactivation of communication protocols, operating parameters of the ballast.
[0009] The at least one application software can provide an application programming interface, make it available and / or change it.
The microprocessor can execute a hardware abstraction subsystem via which the at least one application software accesses the programming interface and / or the signaling interface.
The programming interface can be a wireless and / or wired interface, in particular a Bluetooth, WLAN, LAN, GPIO, and / or Zigbee interface.
The signaling interface can serve to connect at least one signaling unit, e.g. a switch, a button, a timer, a remote control, an active or passive sensor, e.g. a presence detector, a brightness sensor, a humidity sensor, a temperature sensor, and / or a microphone.
[0013] The signaling interface can be designed as a USB, DALI, DSI, SPI and / or 1 ° C interface.
The ballast can be set up to control the lighting means, in particular the LED, preferably depending on a functionality specified by the application software.
[0015] The programming interface can be blocked and can be activated by entering and / or transmitting a code.
The ballast can communicate with other ballasts and / or at least one converter via at least one interface, in particular wirelessly and / or wired, e.g. by means of a bus (DALI bus) and / or by radio transmission.
The application software can enable and / or block a function provided at least by the programming interface, the signaling interface and / or the application programming interface.
[0018] All interfaces can be arranged on the at least one edge of the board. The microprocessor can be a one-chip system.
In a further aspect, a sensor for a lighting system is provided, comprising a microprocessor with at least one memory unit and a circuit board on which at least one programming interface, preferably accessible from outside the sensor, and at least one signaling interface, which is preferably also accessible from outside the sensor is attached, the microprocessor being configurable via the programming interface, and at least one application software executable by the microprocessor being transferable to the at least one memory unit via the programming interface, the application software influencing at least one of the following functionalities of the sensor: Interaction with other sensors and participants in the lighting system, evaluation of signals transmitted to the signaling interface, control of one or more ballasts, activation / deactivation ng of interfaces of the sensor, activation / deactivation of communication protocols, and acquisition, setting and / or evaluation of operating parameters of the sensor (IS) and / or the other sensors.
In yet another aspect, a lighting system or a lamp with a ballast, as described above, and / or a sensor, as described above, is provided.
The invention will now also be described with a view to the figures. The figures show: [0023] FIG. 1 a schematic overview of the invention,
Fig. 2 shows exemplary arrangements and
3 shows an embodiment of the invention.
In the ballast, a microprocessor is provided which is connected to at least one memory unit so that it can access the memory unit and read data from there and write data into it.
The microprocessor (e.g. ARM Cortex-A5x, ARM Cortex-A7x, ...) is preferably provided on a circuit board which has at least one edge and on which the memory unit can also be attached. The microprocessor and / or the memory unit can also be provided on a separate circuit board which is connected to the circuit board, e.g. by means of a socket connection. The board has a programming interface on the at least one edge and at least one signaling interface, which can also be attached to the at least one edge of the board, but also on a further edge of the board.
At least the programming interface is accessible from outside the ballast. The programming interface can be set up for wired and / or wireless communication. In particular, the programming interface can be a radio interface (Bluetooth, WLAN, ZigBee, RFID, ...) and / or a wired (parallel, RS323, USB, JTAG, GPIO, ...) interface. It is therefore not always necessary, for example, for the programming interface to be exposed to the outside. Rather, the programming interface can also be accessed inductively from the outside, for example, in order to transmit data from a programming device to the memory unit and / or the microprocessor by means of the programming interface, for example. This ensures that the ballast can be configured appropriately for its location and, for example, can have a prescribed degree of protection (International Protection Code (IP) certification).
It is of course also possible that the programming interface is exposed to the outside. The programming interface can thus be accessed via a wired connection. A programming device can thus be connected to the programming interface by means of a cable and data can be transmitted to or from the storage unit and / or the microprocessor.
Data transmitted via the programming interface, which can then be stored in the memory unit, can be configured for the microprocessor or its information processing. In particular, application software (also called "app") can be transferred to or into the memory unit. This application software is then executed by the microprocessor, it being understood that the microprocessor can also execute a large number of application software components.
The application software stored in the memory unit, which is executed by the microprocessor, can then influence one of the following functionalities of the ballast.
For example, the interaction or the evaluation of sensor data, which are supplied by sensors interacting with the ballast, can be defined or changed. In particular, the sensors can transmit signals to the ballast via the signaling interface. These signals are then evaluated by the at least one application software and processed in accordance with a definition given by the application software.
Instead of sensors, other signal generators such as switches, buttons, or control input devices (also generally called "controls" in the field of the invention) can of course deliver signals via the signaling interface to the ballast. These signals can, as described above for the signals supplied by sensors,
then likewise evaluated and processed according to the specifications defined by the at least one application software.
The application software can, however, also specify how the ballast interacts with the connected signal sources (sensors, signal generators, ...). In particular, it can be determined which signals are evaluated or processed and with which type of signal generator the ballast works together. In this way, the signal sources can be defined whose signals are evaluated at all. Signal sources or interfaces can also be blocked or released and it is possible, for example, that the functional scope of the ballast can be expanded or limited in this way.
The at least one application software can also influence the control with which the ballast controls the at least one lamp, for example. Thus, in particular depending on the incoming signals from the signal sources, the lighting means can be controlled by the application software. Here, too, the behavior of the connected lighting means and / or devices can be changed, for example by transferring new application software. Application software that is stored in the storage unit of the ballast can of course also change the evaluation of the signals.
Another functionality of the application software is that it can also be used to change the functionality provided by the ballast, and in particular interfaces provided can be activated or deactivated. The functional scope of the ballast can also be controlled in this way. Communication protocols that are provided for the communication between the ballast and communication partners, for example other operating devices or control centers, can also be activated or deactivated. The ballast can be adapted for different application scenarios, for example by only requiring individual communication protocols. On the other hand, the functionality of the ballast can also be expanded if additional communication protocols have to be added or deactivated. This can be the case, for example, if the application scenario for the ballast changes. Overall, the application software thus allows the operating parameters of the ballast to be defined and changed.
It is to be understood that the at least one application software in the memory unit can also be updated and changed. This can then also be done via the programming interface. In addition, it is possible for more than one application software to be stored in the memory unit and executed by the microprocessor. Additional features of the ballast can be activated or deactivated by adding application software. For example, it is possible for an application to provide only a basic functionality, while further application software deactivates or activates additional functionalities of the operating device.
The application software can also provide, make available or change an application programming interface. This application programming interface can then be used to add further software components to the application software which also relate to functionalities of the operating device, and in particular to activate or deactivate functions.
The microprocessor preferably executes a hardware abstraction subsystem (HAL, Hardware Abstraction Layer). The application software then preferably accesses the programming interface and / or the signaling interface via the hardware abstraction subsystem. The programming interface can be a wireless and / or wired interface.
The signaling interface can also be a DALI or DSI, SPI and / or 1 ° C. interface.
The programming interface can also be designed so that programming or the transmission of application software is initially not possible. A
Programming interface that is initially blocked in this way may require a code or an activation key, e.g. a cryptographic key to which the ballast must be transmitted in order to activate the programming interface. In particular, the programming interface can only be activated (for example for a predetermined period of time) when the programming interface has been activated accordingly.
In addition, the programming interface can only be activated if, for example, a programming device is positioned at a certain distance from the programming interface or is connected to the programming interface. The programming device can then automatically transmit an identifier or a key via the programming interface to the microprocessor, which is recognized by the latter (e.g. by means of the NEC). The microprocessor can then enable data to be transferred to the memory unit and thus enable the programming interface to be activated.
The ballast can also have wired and / or wireless communication interfaces, for example to communicate with other ballasts or operating devices. These communication interfaces are also attached to one edge of the board. The ballast can also have a converter interface via which one or more converters can be connected to the ballast.
The application software or the microprocessor can thus control one or more converters connected to the ballast. The microprocessor is in particular a one-chip system (system on a chip, SoC). The interfaces made available in the ballast are in particular all attached to at least one edge of the board.
The shape of the board corresponds essentially to an n-gon. For example, the circuit board can be substantially triangular or trapezoidal in shape, and the interfaces provided can be arranged accordingly along the edges of the circuit board. The microprocessor with memory unit can be connected to the circuit board wirelessly or by wire.
A corresponding exemplary illustration is shown in FIG. 1. Fig. 1 shows a circuit board 1 of a ballast V, on which a microprocessor 2 and a memory unit 3 are arranged. The essentially trapezoidal configuration of the board 1 shown as an example has four edges, which are identified by a, b, c and d. Different interfaces can now be attached to the edges a, b, c, d of the board 1, which interfaces can also be assigned to different functional groups. For example, the interfaces on a first edge can be set up for communication with converters or lighting systems. At the first edge a, interfaces are shown as examples, which e.g. communication using DALI, SPI and / or 1 ° C (Inter-Integrated Circuit) buses / protocols are designed as the communication interface. On the other hand, interfaces for communication with control units (“controls”) can be provided on a second edge b; a DALI, a Bluetooth (Bluetooth Low Energy, BLE) and a LAN interface are shown by way of example on the second edge third edge c an interface P is provided.
The interface P is preferably the programming interface. As already mentioned, this can be protected against access by mechanical or software measures, or it can be selectively activated. A programming device 4 is also shown by way of example, from which at least one application software A can be transmitted to and / or from the interface P, which can also be a Bluetooth (e.g. BLE) interface. Finally, at a fourth edge d interfaces are provided which e.g. serve to connect sensors and / or other hardware that are to be connected to the ballast. A WLAN (or WiFi), a USB and a serial RS232 interface are shown here as examples. These can e.g. enable communication with a microphone arrangement 5, a moisture sensor 6 and / or a presence sensor 7. The sensors can be active or passive.
In Fig. 1, a converter or lighting system 8 is also shown, which can be communicatively connected to one of the interfaces on the first edge a. In this respect, the interfaces at edge a can also be referred to as converter interfaces. With the interfaces at the second edge b, e.g. a coupling element 9 (e.g. a switch or router), via which the ballast can be connected to other components / ballasts. A time control circuit 10 or time switch can also be connected to one of the interfaces at the second edge b. In addition, communication with a remote control 11 via radio or infrared and corresponding interfaces is also possible. In addition, the signaling interface is designated by S as an example. In principle, any interface different from the programming interface is to be regarded as the signaling interface S.
It is to be understood that the circuit board 1 does not have to be a regular geometrical body. The interfaces arranged on the at least one edge can also be arranged one above the other in the manner of a pyramid. In particular, a further interface arranged above / below an interface can be arranged slightly offset to the interior of the board 1. The programming interface can be protected against misuse in that it can be separated in terms of hardware and / or cryptographically secured.
The signaling interface can be used to connect switches, timers, remote controls, etc. A separate interface can be provided for other signal transmitters such as sensors (motion sensor, brightness sensor, humidity sensor, microphones, presence sensor, ...). The corresponding signals can, however, also be fed to the signal recording interface.
The signaling interface and other further interfaces are preferably USB interfaces or also DALI interfaces. The microprocessor can provide suitable microprocessor interfaces for connecting the interfaces. The processing by the microprocessor can be configured via the application software, as explained above, and the application software can thus change the ballast and in particular a lighting system or its functionality. It is thus possible for a user to create application software which then enables specific functionalities of the ballast. Using the hardware abstraction subsystem, the at least one application software can then be used independently of an implementation of the interfaces and configurations used. For example, the microprocessor can be connected to a converter via a fourth interface. This interface can be designed as a DALI, SPI, or I ° C interface. Alternatively, the microprocessor can also be integrated in the converter.
In addition to the communication options already mentioned, other communication paths are also possible, for example via the signaling of the light emitted by the lighting means or via communication by means of PLC (Power Line Communication).
2 shows an example of a possibility in which the microprocessor 2 communicates with one or more converters 20, 21, 22, 23. In FIG. 2a) a lamp 24 with a converter 20 is shown, which has the microprocessor 2 and the memory unit 3.
Further converters 21, 22, 23 of lights (not shown) are also shown, each of which has only one converter but does not provide a microprocessor itself. Communication between the various converters can then take place via a DALI bus, for example. However, only one of the lights or one of the ballasts can be expanded using the application software. However, the application software can also determine the control of the other converters, so that, for example, depending on the configuration of the converter 20 by the application software, a configuration or such an operation can take place that is appropriate to the situation and the place of use.
As shown in Fig. 2b), the microprocessor 2 does not necessarily have to be housed in a lamp or in a ballast, but can also be provided externally. The microprocessor can by means of the coupling element 9 with several stations
be connected to several ballasts, converters or lights 25, 26, 27 in a network, the coupling element 9 being, for example, a WLAN router or a DALI bus master to which several ballasts, converters or lights 25, 26, 27 can be connected. The communication to the ballasts, converters or lights 25, 26, 27 can then be digital via the connection provided, e.g. using DALI or DSI protocol. A microprocessor can of course also be provided in each ballast or in each lamp.
For example, parameters can be set in the ballast by the application software, which for example set a dimming / light level for a room and / or a maximum / minimum operating temperature, or define when an incoming signal is evaluated as a detection of a presence in a room becomes. In addition, the limit and / or threshold values for a humidity, an air pressure, a CO 2 content or a noise level of the environment can be defined, and when they are reached, the application software should then carry out certain actions. The application software can also specify, for example, that an image is recorded via a camera module when certain parameters (for example those supplied by a presence sensor) exceed a threshold value or level.
A DALI interface, a Bluetooth interface, a LAN interface, a PLC interface and / or a USB interface can be provided on the hardware side for communication. One or more microphones can also be provided. As already stated, the application software can also determine how incoming signals are evaluated. For example, filters (noise filters, echo filters, etc.) can be applied to the signals. Parameters and evaluations can also be defined for specific application scenarios (for example, a large room with a large number of office room dividers (cubicles)) or situations for order picking. For example, the size of the room in which an installation is to take place or the number of lights can be defined in an application software, which can then be selected or specified accordingly. The application software can also be used to run test programs.
Various techniques and programming languages can be used as the programming platform for the application software. For example, the application software can be created in JAVA, PYTHON, PEARL, C, C ++, C #, RUBY, GO ....
It should be understood that the above-mentioned ballast is mentioned as a representative of converters, converters, sensors, lights and other participants in a lighting system. The techniques, configurations and protocols listed for the interfaces are essentially interchangeable. The interfaces can either be open to the outside or be covered. A selectively open and close cover of the respective interfaces is of course also possible.
While the board 1 was described above mainly as being arranged in the ballast, it is to be understood that the board 1 can alternatively or additionally also be arranged in other components of a lighting system, for example the lighting system 8. For example, the circuit board 1 can also be part of a sensor or an actuator.
In the following, an intelligent sensor IS is described which comprises the circuit board 1 as described above. Consequently, the description of the ballast V and FIG. 1 essentially also applies to the intelligent sensor IS.
In FIG. 3, an integration of the intelligent sensor IS into a lighting system BS is shown as an example. The intelligent sensor can be connected to the lighting system BS. The intelligent sensor IS can also be connected to a higher-level bus system (e.g. an IPv6 bus system, overlay network, ...) and have a microprocessor 2, a memory unit 3 and, in particular, application software A. Furthermore, the intelligent sensor IS can communicate with the microprocessor 2 in a wired or wireless manner (
dashed double arrow). The microprocessor 2 does not necessarily have to be part of the intelligent sensor IS. The intelligent sensor IS can receive data from several connected sensors NIS which have no intelligence, i.e. in particular no microprocessor and memory, read out and store wired via a bus line BL or wirelessly. Read out data can be processed by the microprocessor 2. The lighting system BS can also have further intelligent sensors and thus connect at least two sensors to one another.
The intelligent sensor IS can also specify or assume functions and / or limit values for the non-intelligent sensors NIS or other intelligent sensors IS. The intelligent sensor IS can have one or more converters depending on the recorded data, e.g. from the non-intelligent sensors NIS and / or own data, control and / or configure.
For example, the non-intelligent sensors NIS can be designed as simple motion detectors or light sensors (e.g. LDR). The intelligent sensor IS can be a thermal imaging camera.
If a detection event is detected by a non-intelligent sensor NIS, the latter can transmit information to the intelligent sensor IS about the fact that a detection event was detected. The application software A of the intelligent sensor IS can evaluate the transmitted information in an application-specific manner and, as a function thereof, control at least one other subscriber T of the lighting system BS, preferably a converter.
The intelligent sensor IS and / or the non-intelligent sensors NIS can also be integrated in one or more converters.
