Description

ILLUMINATION SYSTEM WITH ANALYSIS SIGNAL EVALUATION DESCRIPTION The present invention relates to a lighting system having a lighting device and a transmitting device, which is arranged in or directly on the lighting device, for transmitting a signal. Moreover, the present invention relates to a method for operating a corresponding illumination system.

So-called "beacons" can be combined with lights to provide light-specific or other information

provide. The beacon technology is based on a transmitter or transceiver system. A beacon (in German: beacon or beacon or

Peilsender) is a small, mostly battery-powered

Transmitter that emits a signal at (definable) time intervals, typically on the Bluetooth Low Energy Standard (BLE). The radio signal of each beacon is characterized by a unique identification number (so-called UUID). Beacons can be used to give objects and places a digital identification. Objects (where a beacon is installed) and locations (where a beacon is installed, for example, on a wall) can thus be identified by terminals (eg, smart devices) in the beacon's beacon.

For example, a beacon can be a place

be identified or carried out a location. Placement of one or more beacons in a building area creates a kind of radio-based grid in which a smart device can locate itself via the BLE interface and corresponding algorithms. The

individual identification numbers of the installed

Beacons give a location an identifier that allows a smart device to approximate its position

(basic send area of the beacon can be determined become) . Algorithms on the smart device can be the

Position accuracy z. B. improve signal strengths. It is necessary for the smart device to be able to access information in a repository (eg on a cloud server) (eg identification number and mapping). If a terminal, for example smart device, comes within the range of a transmitter, it can detect the identification number and, for example, determine the location via a server query. Among other things, the location algorithms access the received signal strength of the beacons in the vicinity, in particular as an indicator for the distance to the respective beacon.

Basically, as mentioned, beacons can be installed in lighting or lighting technology. In particular, the advantage is used that a light installation provides a permanent energy access to power the beacon with energy. This in turn results in the advantage that the battery of the beacon does not need to be replaced and thus appropriate

Life cycle costs or processes can be saved. In addition, parameterization of the beacon can be set with higher power consumption without reducing the lifetime of the beacon.

Installation processes of Beacon and lighting technology can also be standardized. Another advantage is a defined locking position of a beacon transmitter, which is well protected against manipulation. A place can thus be given a clear and secure identifier.

An overview of the potential benefits of integrating a beacon into a light installation can be found in the following list:

- It can be used to power the light installation instead of a battery to reduce the life cycle cost of the beacon. - The energy supply of the light installation can be used to adapt the transmission parameters to the service and not to the available residual energy or the parameters of the battery (for example, frequent transmission cycles generate a high accuracy of the services, but also higher energy consumption).

- The replacement of the battery Beacon conventional harbors

Risks, for example with regard to errors in handling.

- The non-availability of the services may be caused by a

Uninterruptible power supply of the beacon can be avoided.

- An installation location below the ceiling is ideal for signal propagation of the beacon.

- An installation location below the ceiling makes that

Overall system more robust against disturbances / shadowing by objects at level of the corridor level as opposed to one

Installation of the beacon itself at floor level.

- A beacon can prevent manipulation / third-party access

(inadvertently, wantonly) are protected.

- Lighting and services (eg location services) can be offered as a one-stop-shop system.

- It is possible to use the secure

Communication network of light installation to

For example, to configure the beacon or to network the beacons.

- A unification of the installation processes of Beacon and LichtInstallation is possible.

- Furthermore, there is the possibility to couple to other system elements of the peripheral building infrastructure via the communication network of light installation, z. B. to elements of safety technology.

- It can be provided a visually appealing system, since the beacon is not visible in the

Light installation can be accommodated.

Fig. 1 shows a schematic representation of the integration of a beacon in a light installation. A central beacon Bl is arranged on an electric lighting device BE, which indicates the physical connection PV1. The Beacon Bl is optionally a module M with

Data processing unit DV and data interface DS assigned. The Beacon Bl is wireless

Communication connection KVl with a terminal E in

Connection. It can also be several terminals for the

Communication with the Beacon Bl will be available. The beacon Bl together with the terminal or terminals E form a data transmission system DT.

The beacon Bl can be in communication connection KV2 with one or more further beacons B2. Furthermore, a communication link KV3 to a

Infrastructure IE, z. B. Internet or central services server exist. The infrastructure device can serve to control and / or transmit information. The local beacon Bl of the electric lighting device BV can serve as a pure transmitting device or as a combined transceiver device.

In a deployment example, people and equipment

Where appropriate, the challenge of orienting, navigating, or finding other local digital services within an area (eg, apps or app features, Google Maps, Lightyfy lighting control, etc.). The light installation with integrated beacon in one area becomes a location or orientation system for these potential benefits. With the thus realizable self-location of the terminal services can now be provided, such as navigation or the provision of location-specific information.

One aspect of beacon technology is the ability to configure typical parameters such as

Signal strength and transmission interval of the beacon. With Different configurations can be different

Application scenarios are supported individually. If a high quality of service (accurate localization in short

Distances) is required (such as in an indoor navigation), z. B. very short transmission intervals

configure.

Currently the Beacon batteries are used for the energy supply. The need to change these batteries in regular cycles, results in a high

Effort and correspondingly high life cycle costs for the beacon.

A high service quality - for example high

Locating accuracy, long range, short transmission interval - requires comparatively much energy at the transmitter module, so that the battery of a battery-powered beacon must be replaced after a short time (eg after one month). Any replacement of a battery also carries the risk that the functionality of the positioning system is adversely affected by a small change in position or incorrect handling of the beacon.

If necessary, there is a risk that the operator (eg owner of a supermarket) will face the energy shortage of the

Beacon is unaware or will not find the beacon if there is not enough residual energy left. However, the services of the beacon (eg navigation) should be permanently available to the user. This requires an uninterruptible power supply.

The installation or installation of the beacon on or in or as part of the light installation or of a light source would make it possible for a battery-operated beacon, the energy supply of the light installation (eg ballast of the light or the bulb) for the energy supply of the Beacon to use and thus the battery of the Beacon too Substitute and counteract the associated problems (see above).

Specifically, the light installations / lights or

Illuminant (hereafter briefly lighting device) with

integrated transceiving device or transmitting device (hereinafter briefly transmitting device, eg Beacon) in a service area, eg. B. Parking area for motor vehicles, such as a parking garage, installed. It exists the

The challenge is that, for example, an operator of a corresponding service area must determine whether a parking space is already occupied, ie. H. whether a motor vehicle is parked on it, or whether the parking lot is not occupied.

Conventional solutions for detecting the presence of a vehicle in a parking lot are complex and / or expensive.

The object of the present invention is therefore to provide a convenient monitoring option for a service area. For this purpose, a corresponding method should also be specified.

According to the invention this object is achieved by a

Lighting system according to claim 1 and a method according to claim 14. Advantageous developments of the invention will become apparent from the dependent claims.

According to the present invention, therefore, a lighting system with a lighting device and a transmitting device, which in or directly at the

Lighting device is arranged to send a

electromagnetic signal (in particular radio signal) having a specific for the transmitting device

Identification information provided. The

For example, transmitting device is integrated directly into the housing of the lighting device or attached to the housing of the lighting device. The transmitting device may be, for example, a beacon or a Wi-Fi transmitter. The identification information becomes used, for example, for locating in order to be able to determine at the receiving end from which transmitting device (whose position is known) the received signal originates. This signal can now be used simultaneously to detect the presence of an object. Alternatively, the

Identification information can also be used for a luminaire control. Furthermore, the transmitting device can be fed via the same power supply as the

Lighting device. For example, the transmitting device can be supplied with power from a ballast of the lighting device.

In addition, the lighting system includes a

Receiving device that (possibly physically from the

Transmitting device separated) in a fixed local

Relative to the transmitting device, for receiving an analysis signal caused by the signal and for generating a corresponding received signal. For example, the transmitting device is mounted at a first location and the receiving device at a second location. This solid

Local relationship of the two institutions to each other is important to appropriate transmission or

Quantitative and qualitative analysis of reflection signals.

Furthermore, the lighting system has a

Evaluation device for evaluating the received signal

in terms of signal strength. The signal based on a reflection is thus evaluated at least with regard to its signal strength. Possibly. However, evaluations with regard to running time, polarization and the like can also be carried out. Overall, by such a lighting system thus an area with the help of one or more

Lighting devices are monitored by reflections.

In one embodiment, the receiving device also has a transmitting unit for transmitting an electromagnetic

Signal and / or the transmitting device also a Receiving unit for receiving an electromagnetic

Signal on. Thus, a plurality of transceiver devices, each of which is the same design, can be used to monitor a service area.

Optionally, the transmitting device and the

Receiving device (optionally together with the

Lighting device) may also be integrated in a common housing. Preferably, the evaluation device is designed to perform a pattern analysis of the received signal in order to recognize a predetermined object. The receiving device is favorably designed in this embodiment so that it can take a two-dimensional image and generate a corresponding image signal as a received signal. The evaluation device then performs as part of a

Image processing through a pattern analysis. As an object, for example, a motor vehicle can be detected, whose

(metallic) surface provides for appropriate signal reflections.

The evaluation device can also be designed to determine a number and / or position of detected objects. This means that the image processing or

Pattern analysis is refined so that even individual

Objects in the image can be localized. From this a corresponding position can be determined.

In a further preferred embodiment is between the transmitting device and the receiving device a

in particular meshed communication network established. The transmitting device and the receiving device form nodes of such a meshed communication network. Of course, a plurality of other transmitting devices and / or

Receive receiving devices on the communication network. In particular, the transmitting equipment and

Receiving devices in this case be "mesh-capable" and can build the meshed communication network independently.

Furthermore, the evaluation device can be connected to the

Communication network to be connected, the

Receiving device, the received signal via the

Communication network transmits to the evaluation. The evaluation device is in this case a separate node of the communication network. In particular, such a central evaluation device can be installed, which the

Receive signals of all receiving devices receives and evaluates. Not everyone has to do this this way

Receiving device with an evaluation device

be equipped.

In addition, the evaluation device can be designed to receive a static object from a dynamic object

differ. The evaluation device can thus detect whether the object in the image is moved or not. This is favorable, for example, when a parking space is to be monitored.

In a special embodiment of the illumination system, the latter has, in addition to the transmitting device, at least one further transmitting device, but the receiving device is the only device of respective signals. This

means that a single receiving device receives the signals of all transmitting devices. As a result, a simplified reception and evaluation structure can be created.

In a special embodiment, the evaluation device is part of a ballast of the lighting device. In this case, the data processing capacity of the ballast for the evaluation of the received signals of

Receiving device used. This can be a

realize simplified signal processing structure. In a further embodiment, the

Evaluation device integrated into the transmitting device, and the received signal is transmitted via the communication network to the transmitting device. In this way, a module can be provided, wherein in a housing both the transmitting device and a corresponding

Evaluation are integrated. It can the

Evaluation device, the power supply of the

Use transmitting device.

Furthermore, the transmitting device and the

Receiving device to be set up to independently build a meshed network. This allows the

Transmitter and the receiving device can be easily integrated into a network or as

"Germ cell" build a new network.

Furthermore, the analysis signal may be a signal that has been generated by attenuation or reflection from the signal. For example, an object may reflect the signal, or the signal may shine through the object, so that the signal from the

Detection device registered signal is a reflection ^¬ or a damped transmission signal. In the context of a special application becomes a

Parking arrangement provided with a plurality of parking spaces and a lighting system with the above features, wherein the evaluation device free

Parking spaces can be determined. The evaluation device is thus designed so that it can determine from the received signal or the received signals whether a parking space is occupied or not. The evaluation system should be able to recognize primarily vehicles, but also possibly other objects. In a specific embodiment of the parking space arrangement, the lighting system has a plurality of lighting devices and a control device which is designed to lead to a free parking space by means of the lighting devices or to display it. The control device can thus control the lighting devices such that the

Lighting devices such as a running light lead to a free parking space. Alternatively or additionally, a free parking space can also be illuminated by a special lighting by means of the lighting devices.

The above object is also achieved by a method for operating a lighting system with a lighting device, a transmitting device, which is arranged in or directly on the lighting device for wireless transmission of a signal with a for the

Transmitter specific identification information, through

Receiving an analysis signal caused by the signal by a receiving device which (possibly physically separated from the transmitting device) is in a fixed local relationship with the transmitting device,

- Generating a corresponding received signal by the receiving device and

- Evaluating the received signal in terms of his

Signal strength by an evaluation.

The above related to the lighting system

addressed refinements and advantages are mutatis mutandis transferable to the inventive method. At the same time functional signs of resources of

Illumination system corresponding method features. The present invention will now be explained in more detail with reference to the accompanying drawings, in which:

Fig.6 a parking lot with dynamic detection.

The examples described in more detail below

It should be noted that the individual features not only the described feature combinations, but also in isolation or in other technically meaningful

Combinations can be realized.

With the present invention, for example, the

Presence of objects, eg. B. motor vehicles, on open spaces, z. B. can be achieved in parking lots. This succeeds

for example by means of a system of a primary

Transceiver or transmitter (hereafter short transmitter) in / on or as part of a

Light installation / luminaire or a light source

(hereinafter briefly lighting device, eg Beacon) and a secondary (transmitting) receiving device, the

in particular pronounced as a pure receiving device and can also be arranged on a light source. A reflected or transmitted signal (analysis signal) which was originally transmitted by the transmitting device (eg BLE signal) is detected by the receiving device and subsequently evaluated. The signal contains a unique identifier or identification information, with which it can be clearly assigned to the corresponding transmitting device.

In one embodiment, for example, a

Transmitting device (eg Beacon) to a lighting device (in particular on a ballast) mounted, wherein the transmitting device is powered by the lighting device with energy. One possibility in which no complex energy converter is required is the electrical connection of the transmitting device parallel to LED modules or to a group of LEDs or possibly to an LED carrier module. Another possibility is to use existing energy and communication interfaces

digitally controlled light installation for the

Power supply of a transmitting device to a

Lighting device to use, this interfaces primary side of the electronic ballast and

Comprises communication interfaces and / or combined energy and communication interfaces. Because the

digitally controlled light installation at the

Primary interface is always powered, even if the light z. B. is issued, an energy access for the transmitting device available. A transmitted or reflected signal originally transmitted by the primary transmitter (eg, BLE signal) is detected by the secondary device. In this case, a received signal, which may be an image signal for example, is generated.

For example, a pattern analysis of the

Receive signal determines whether or how many objects, such. B. motor vehicles are (at which position) in the area. An example of such a pattern analysis is the so-called fingerprinting method. Thus, by detecting changes in the received

Signal / reflected signal on the occupancy of an area, z. B. Parkplatzes, be inferred by a vehicle. An advantageous embodiment provides that both the primary Sendevorichtung and the secondary

Receiving device are part of an overall composite of lights or bulbs with integrated transceiver devices in a service area, the individual devices can each form both a primary and a secondary transceiver.

For example, the receiving one

System element around a beacon, which in turn acts as a sender.

Furthermore, a specific expression is proposed, which is a communication network between the

different participants (send and / or

Receiving devices) of the overall composite of transceiver devices or receiving devices in / on or im

Surrounding light installations / lights or bulbs. The communication network can be wired (eg DALI bus, Power-Over-Ethernet / Ethernet, Powerline etc.) or wireless (eg Bluethooth, WiFi,

Zigbee, etc.). In both cases, the network topologies are preferably "mesh" and / or "point-to-point" and / or serial, i. Bus architecture, feasible. Thus, the transmitted signal of a transmitting device after reflection on an object is received, for example, from another mesh-capable (transmitting) receiving device. This transmits the received data, for example, also via a mesh Net zwerk to a central

Information processing device. In this

Information processing device or evaluation then takes place the evaluation by means of pattern analysis (s).

Possibly. can also be distinguished between static and dynamic detection. For example, even moving objects, such. B. moving vehicles, are detected via the dynamic change of the transmitted or reflected signals, for. B. at the entrance / access to the service area. Possibly. the pattern analyzes have to be adapted. The transmitted or reflected in the service area signal is, as described, from a secondary

Receiving device (eg monitoring system) or (transmitting) receiving device resumed. For this purpose, different variants are proposed:

Version 1 :

Separate central monitoring system / receiving device that receives only the transmitted or reflected signals, and / or subsequently evaluates.

For example, for ten primary transmitting devices (e.g.

B. Beacon) in corresponding light installations a single

Monitoring system / a single receiving device for

Commitment. This one acts as a gateway to a central one

Server.

Variant 2 :

A secondary (transmitting) receiving device on a

Illuminant, as mentioned, if necessary, in turn, may occur as the primary transmitting (receiving) device itself.

Variant 3:

A primary transmitter is at the same time transmitter of the signal and receiver of the reflected signal.

Variant 4:

Objects, e.g. As automobiles, may themselves act as a transceiver (eg, beacon) and may be detected by the monitoring system.

The pattern analyzes for the identification of changes in the signal take place, for example, in one

Information processing device or a

Evaluation. This can be realized in various ways:

Version 1 : _Ί ,

1 b

Within the evaluation device in / on as part of

secondary transceiver device or

Receiving device. Variant 2 :

Within the evaluation device as part of the electronic ballast (ECG) of the light installation or the light in which the secondary (transmitting) receiving device is optionally integrated.

Variant 3:

Within a central information processing or evaluation device (eg a central service server), the pattern analysis is carried out, wherein a

Communication link between the secondary (transmit

) Receiving device with this central instance exists.

Within the evaluation device of the primary transmitting (receiving) device, the pattern analysis can also be performed. There is a communication network

between the different transceiver devices on the bulbs available, z. B. a mesh Net zwerk.

In one form, a (re-) notification of a

Presence information to the light installation / luminaire (eg to the electronic ballast ECG) in order to be able to access the

Light installations / lights free parking visually

to demarcate occupied parking spaces. The transmitting devices on the bulbs can be mesh-capable transmitting (receiving) devices that can build together a meshed network, i. each device may act as a network node that communicates with one or more other devices (primary and / or secondary) in the same installation area wirelessly and / or via the communication network of the

Light installations / lights is connected. Within this meshed network, the information is passed from node to node.

In the case of a communication link between

If there are several installed light installations with integrated transceivers (eg via a mesh network between several installed transceivers or via an additional external network), feedback of the presence information to the light installations can be used to inform the user, in particular the user Driver of the vehicle dynamically on the light installations to point the way to an unoccupied parking (parking guidance system by means of lighting). Hereinafter, various concepts of lighting systems will be described in detail in connection with FIGS. 2-5.

According to the concept of FIG. 2, a primary transmitting device SE (preferably with receiving functionality) is connected to a lighting device LE (cf.

Connection PV 1) emitted a signal SW (eg electromagnetic wave) and reflected or attenuated by an object OB, if present, in the considered service area. The reflected or attenuated signal RW is then from a secondary receiving device EE, which also

Send functionality may have received.

The schematic representation of Fig. 2 also shows the above-mentioned variant 1 (VI) and variant 3 (V3), i. at which point of the overall system, the pattern analysis MA for evaluating the received reflected signal RW done. In principle, the secondary (transmitting) receiving device EE can be in / on or as part of a light installation / luminaire or a lighting device, i. at the lighting device LE, housed or as a separate system element,

For example, be provided only as a receiving device. Variant 1 (VI) provides that the Pattern analysis MA (eg fingerprinting) on an information processing unit IV in the secondary

Receiving device EE takes place, whereas variant 3 (V3) is an evaluation of the signals in a central

Infrastructure IS for services provides. This can be, for example, the Internet or a central service server. Furthermore, in the here

described embodiment, a communication link KV4 between the secondary receiving device EE and the

Infrastructure IS necessary.

The illumination system of Fig. 2 shows further details. In particular, the lighting device LE, for example, an LED board LP, a ballast ECG and a

Energy interface ES on. There is a communication link KV5 between the LED board LP and the ballast ECG. In addition, from the power interface ES to the electronic ballast ECG

Power transmission channel EK1 and electronic

Ballast ECG to the LED board LP on

Energy transmission channel EK2.

The transmitting device SE has a

Information processing device IV and also an energy interface ES. Both are interconnected via a communication link KV6 and one

Power transmission channel EK3. Furthermore, there is between the power connection point ES and the electronic

Ballast ECG of the lighting device LE on

Energy transmission channel EK 4.

The receiving device EE has in addition to the

Information processing unit IV also a

Energy interface ES. Both components are connected via a KV7 communication link and a

Power transmission channel EK5 in contact with each other. In addition, an occupancy indication BZ can be provided for the area to be monitored, in particular a parking space. With their help, the occupied

Parking spaces are displayed. She stands here in one

Communication link KV8 with the infrastructure device IS.

Furthermore, a mains supply device NV is provided which supplies, for example, an AC voltage of 230 V. It has, for example, a power transmission channel EK6 to the energy interface ES of the lighting device LE, a power transmission channel EK7 to the infrastructure device IS, a power transmission channel EK8 to the

Occupancy indicator BZ and a power transmission channel EK9 to the power interface ES of the receiving device EE

(List not final).

In connection with FIG. 3, a further concept of a lighting system will now be explained. Compared to the concept of Fig. 2, the object OB (e.g.

Motor vehicle or road surface) reflected signal RW received from a monitoring system MS. It can be a

single monitoring system MS received signals from multiple primary transmitting devices SE. The

Evaluation, z. B. the pattern analysis, takes place in this

Embodiment within the monitoring system MS. Between the monitoring system MS and the occupancy indicator BZ, which is also provided in the present example, there is a communication link KV9. Further, a

Energy transfer channel EK10 from the

Power supply device NV provided to the monitoring system MS. With regard to the description of the rest

Components and connections of this embodiment will be referred to the description of Fig.2.

In the concept according to FIG. 4, it is provided that both the primary-side transmitting device SE and the secondary receiving device EE form part of an overall composite Lighting devices LEI, LE2 with integrated transceivers SEI and SE2 are in a service area.

In a specific case, the transmitting device SEI is used as a primary-side transmitting device and the transmitting device SE2 as a secondary-side receiving device. Conversely, of course, the transmitting device SE2 for sending and the transmitting device SEI serve to receive. In addition, the entire system here has a communication network KN between the individual subscribers SEI and SE2 (possibly further transceiver devices) at the lighting devices LEI, LE2, etc. By way of example, connection points "a" and "b" are provided in FIG. 4, which are each connected to one another. The communication network KN can in particular

wirelessly (eg BLE, WiFi, Zigbee, etc.). The net topologies "mesh" and / or "point-to-point" and / or "serial", ie BUS architecture, can be realized, thus the transmitted signal SW (eg electromagnetic wave) of the transceiver becomes After being reflected on the object OB, it is received by the other transceiver SE2 as a subscriber to the communication network KN, which transmits the received data, for example, via a mesh network as the communication network KN to a central transceiver

Information processing device ZI. This may be, for example, an infrastructure for services (eg

Internet or central service server).

In the central information processing device ZI, for example, the evaluation is carried out by means of

Pattern analysis MA. With regard to the other components and connections, reference is again made to the description of FIG. 2. In addition, in Fig. 4 nor the variant 2 of the pattern analysis MA indicated in the lighting device LEI or LE2 and in particular in the electrical

Ballasts ECG can take place. 5, a further concept of a lighting system is indicated, in which the signal RW reflected by the object OB is received by a monitoring system MS. The

Monitoring system MS is in / on or as part of a

Luminaire / light installation, ie. arranged on the lighting device LE2, which is the physical

Connection PV2 implies. In this case, the monitoring system MS can receive reflected signals RW from a plurality of transmission signals.

Receive devices or transmitting devices SE received.

The evaluation, z. As the pattern analysis is done in this embodiment within a central infrastructure IS for services (eg, Internet or central service server). There is a communication link KV10 between the monitoring system MS and the central

Information processing device IS. These

Communication link KV10 is designed, for example, wirelessly or by wire and can via the

Communication connections of the light installation / lights, i. the lighting devices LEI and LE2 take place. As in the example of FIG

Power transmission channel EKll of the

Power supply device NV to the power interface ES of the second lighting device LE2 be provided. Furthermore, a power transmission channel EK13 may consist of the electronic ballast ECG of the second lighting device LE2 to the monitoring system MS.

In addition, there is a power transmission channel EKll between the network supply device NV and the

Energy interface ES of the second lighting device LE2 and a power transmission channel EK12 between the

Mains supply device NV and the central

Information processing device ZI (see Fig. 4).

In connection with FIG. 6, the application of an illumination system described above for parking spaces will now be described. A parking lot PA has a variety at parking PP. Some of these parking lots are already occupied by motor vehicles KF. The park area PA has a driveway ZF and an exit AF. At the access ZF, a first lighting device LEI including transmitting device SEI is provided, the signal SW transmitted by the transmitting device SEI is reflected by the object OB, in this case a motor vehicle, and reaches a receiving device EE1 as a reflected wave or as a reflected signal RW.
