Description

LUMINAIRE CONTROLLER WITH RULE ENGINE Field of Invention The field of the invention relates to luminaire controllers for use in luminaire networks comprising one or more luminaires. Particular embodiments relate to luminaire controllers for controlling one or more luminaire components, and in particular a light source, of a luminaire.

Background The development of luminaire networks has increased significantly over the last couple of years and such networks are being installed using luminaires in cities or along roads. The node of an outdoor luminaire network typically comprises an outdoor lighting controller (OLC), also called a luminaire controller, capable of managing one or more lighting devices and/or other luminaire components, such as one or more sensors.

The OLCs may form a large mesh network in which the communication links are based e.g. on IEEE802.15.4. The network may be managed from the backend by means of a plurality of segment controllers connecting the mesh networks with the Internet. In such a solution an OLC includes a CPU and a communication interface based on IEEE802.15.4. In addition or alternatively, the OLC itself may be capable of communicating directly with the Internet.

Often it is desirable to control the light source and other luminaire components in function of certain inputs, such as the time, the angle of the sun, an environmental input such as a weather related input, a movement related input, etc. For example, it may be desirable to only power a light source when there is insufficient sunlight and when a person or a vehicle is passing near the luminaire, or when there is an emergency situation, or when there is a lot of traffic, etc. Also, the light level may be adjusted in function of various inputs, such as e.g. the weather conditions, the traffic conditions, etc. For example, it may be desirable to have a higher light level in case of bad weather and/or in case of heavy traffic. Also, it may be desirable to control a camera based on one or more inputs.

Monitoring of environment data such as audio, video, image, air quality data is being implemented more and more often in luminaires and it is desirable to be able to control various laminaire components in function of the monitored data. Such controlling may provide a sense of safety and security in public spaces, e.g. parks, roadways, etc.

In existing solutions luminaire components, such as a light module, are controlled by a luminaire controller based on locally sensed data and/or based on data received from a remote location. However, when a sensor is added or when it is desirable to change the controlling, the controller need to be adapted, and this cannot be done in a flexible manner.

Summary The object of embodiments of the invention is to provide a luminaire controller which provides a structured and flexible way of controlling one or more luminaire components.

According to a first aspect there is provided a luminaire controller for controlling one or more luminaire components based on one or more inputs, said luminaire controller comprising a control means configured to control a luminaire component of the one or more luminaire components in accordance with a rule set comprising a plurality of rules. A rule of the rule set comprises: - a priority indication, 5 - at least one control output, - an optional condition requirement for at least one input of the one or more inputs. The control means is configured to determine a rule of said rule set by selecting the rule with the highest priority indication out of all rules for which the condition requirement is fulfilled or for which no condition requirement is present, and to control the luminaire component based on the at least one control output of the determined rule.

The one or more inputs may be “physical” inputs, such as data locally sensed in the luminaire, and/or “virtual” inputs, such as inputs received from a remote device. The physical inputs may be obtained in a wired or wireless manner from a local sensor. The virtual inputs may be data computed inside or outside of the luminaire and/or data created outside of the luminaire and provided to the luminaire.

By defining rules in this manner, there is provided a structured way of controlling a luminaire component. Indeed, when e.g. a sensor, e.g. a light sensor, is added and it is desirable to control the luminaire component, e.g. a light module, in function of an input of the light sensor, it is possible to add a rule to the rule set with an appropriate priority indication, at least one appropriate output such as a light intensity value to be set by the light module, and a condition requirement defining a condition for the at least one input. For example, an additional rule may be added to switch on the light module (e.g. corresponding with a control output “light level = 90%") when the sensed light is below a certain level, and this rule may be added with a higher priority than the already installed rules.

According to an exemplary embodiment, the luminaire component is a light module, and the at least one control output comprises at least one light related output.

In many luminaires a light module may be controlled according to a dimming profile, and this dimming profile may depend on a number of “physical” or “virtual” inputs such as time, the angle of the sun, etc. By working with rules with different priorities, such dimming profiles can be defined in a convenient and flexible manner.

Preferably, the at least one light related output comprises any one or more of the following: a light level, alight temperature, a light colour, a light pattern.

To implement a dimming profile dependent on various inputs, such as an input from a light sensor, the light intensity can be used as a control output in a number of rules of a rule set. However, in addition or alternatively, also other settings of the light module may be varied such as a light temperature, a light colour, a light pattern. For example, a control output related to a light pattern may be set based on a rule using as an input a measurement of a detection sensor configured to detect whether a person or vehicle is passing. Also, the light temperature and/or the light colour may be varied in function of at least one input e.g. the date. Again, rule sets with a plurality of rules as defined above, allow implementing this way of controlling by using rules with different priorities.

According to an exemplary embodiment, the one or more luminaire components comprise any one of the following: an environmental sensor such as an image capturing device, a sensor, an irrigation means, an audio capturing device, a communication device, a solar panel, an advertising device.

Indeed, also those components may be controlled advantageously using a rule set as defined above. For example, an audio capturing device or a camera or an irrigation means may be switched on only if a certain trigger is received. The condition of the rule can then be a condition dependent on the trigger, the control output can then be “switch on”, and the priority should be higher than that of another rule putting the audio capturing device in the switched off state.

According to an exemplary embodiment, the at least one control output comprises an output indicating whether the laminaire component has to be switched on or off.

This is an output which may be useful for many luminaire components, see also the example given above for the audio capturing device.

According to an exemplary embodiment, the one or more inputs comprise any one or more of the following: a time, sensor data, such as light sensor data, an angle of the sun, an input for indicating an emergency, a pollution related input, a weather related input, an energy consumption related input.

Preferably, at least one of the rules of the rule set comprises a condition requirement for at least one input of the one or more inputs.

Indeed, embodiments of the invention are particularly advantageous when defining rules with condition requirement, as this can be done in a structured and flexible way using the priority indication. According to an exemplary embodiment, the luminaire controller comprises storage means for storing a plurality of rule sets, wherein each rule set is associated with a rule set priority indication, and wherein the control means is configured to control the luminaire component in accordance with the rule set with the highest rule set priority indication.

In that manner, two levels of priority indications are provided, one priority indication within rules of a rule set, and one within the plurality of rule sets. In that manner, the implementation is rendered even more flexible, as a new rule set can be defined and added to overwrite a previous one, by giving the new rule set a higher rule set priority.

According to an exemplary embodiment, the control means is configured to control multiple luminaire components in accordance with multiple rule sets as defined above.

For example, a light source, a camera and an irrigations means may be controlled using three different rule sets. The one or more inputs may be the same or different.

According to another aspect there is provided a luminaire system comprising one or more luminaire components, a laminaire controller according to any one of the previous embodiments for controlling at least one luminaire component of said one or more luminaire components based on one or more inputs, and one or more measurement devices, wherein the one or more inputs comprise one or more input values measured by the one or more measurement devices. The at least one luminaire component may comprise a light source. Preferably, the one or more measurement devices comprise any one of the following: a clock, an astronomical clock, a sensor such as a light sensor or a particle sensor or a fire detector, an image capturing device, an audio and/or noise capturing device.

According to another aspect there is provided a computer program configured for providing a user interface to a user to allow a user to enter, for each rule of a rule set with a plurality of rules, the following information: - a priority indication, 5 - at least one control output, - an optional condition requirement for at least one input. The computer program is further configured for generating a code for said rule set based on said information, and for sending said code for said rule set to a luminaire controller.

In that manner, a user can easily define the rules of a rule set through the provided user IO interface.

According to an exemplary embodiment, the luminaire controller is configured to receive the code defining the rule set through a network such as a cellular network, a mesh network, a star network, etc.

According to an exemplary embodiment, the luminaire controller is included in a luminaire network system comprising an edge routing luminaire controller configured to transmit data through a cellular network, and the laminaire controller is configured to communicate with the edge routing luminaire controller through a mesh or star network.

This will allow transmitting data indirectly to a back-end server via the edge routing luminaire controller or receiving data indirectly from a back-end server. In such networks, a plurality of luminaires may be connected through a mesh network, e.g. a Zigbee network, or through a star network, such as LoRaWAN, with only some edge luminaire controllers capable of performing communication through a cellular network. The data is then first transmitted through the mesh or star network to the edge luminaire controller, and from there to the back-end server, or vice versa.

According to an exemplary embodiment, the luminaire controller is configured to transmit or receive data using an IEEE 802.15.4-based protocol, preferably a Zigbee protocol.

According to a further aspect of the invention, there is provided a computer program comprising computer-executable instructions to perform or control the steps performed by the luminaire controller, when the program is run on a computer, according to any one of the embodiments of the fuminaire controller disclosed above. According to a further aspect of the invention, there is provided a computer device or other hardware device programmed to perform or control the steps performed by the luminaire controller of any one of the embodiments disclosed above. According to another aspect there is provided a data storage device encoding a program in machine-readable and machine-executable form to perform or control the steps performed by the luminaire controller of any one of the embodiments disclosed above. Brief description of the figures The accompanying drawings are used to illustrate presently preferred non-limiting exemplary embodiments of devices of the present invention. The above and other advantages of the featares and objects of the invention will become more apparent and the invention will be better understood from the following detailed description when read in conjunction with the accompanying drawings, IO mn which: Figure 1 is a schematic diagram of an exemplary embodiment of a luminaire network; Figure 2 illustrates a dimming profile and the corresponding rule set according to an exemplary embodiment; and Figures 3-5 are tables of possible rule sets according to various exemplary embodiments.

Description of embodiments Figure 1 illustrates a luminaire network system comprising a plurality of luminaires 1000, a remote device 2000, and a cellular network 3000. A luminaire 1000 is provided with a luminaire controller

100. The luminaire controller 100 is configured for controlling one or more luminaire components 200, 200° based on one or more inputs I, I’, I”. The one or more luminaire components may comprise a light module 200 with a light source 210 and a driver 220 for driving the light source

210. Also one or more other luminaire components 200° may be controlled by the luminaire controller 100, such as any one of the following: an environmental sensor such as an image capturing device, a sensor, an audio capturing device, a communication device, a solar panel, an advertising device, etc. The luminaire 1000 may be provided with the one or more measurement devices 300, 300°, 300” comprising e.g. any one of the following: a clock, an astronomical clock, a sensor such as a light sensor or a particle sensor or a fire detector or visibility sensor, an image capturing device, an audio and/or noise capturing device, etc. A measurement device 300 may be configured to provide an input I to the luminaire controller 100 and to receive a control output S” of the luminaire controller 100. In other words, a measurement device 300 may also be a luminaire component which is controlled by a control output of a determined rule. However, other measurement devices 300’, 300” may provide only an input I’, 1”.

The luminaire controller 100 comprises a control means configured to control a luminaire component, here the light module 200, in accordance with a rule set comprising a plurality of rules. A rule of the rule set comprises: - a priority indication, - at least one control output, - an optional condition requirement for at least one input of the one or more inputs. The control means is configured to determine a rule of said rule set by selecting the rule with the highest priority indication out of all rules for which the condition requirement is fulfilled or for which no condition requirement is present, and to apply the at least one control output {S) of the determined rule to control the luminaire component 200.

A simple example is illustrated in figure 2. The graph of figure 2 illustrates a desired dimming profile. This dimming profile may be implemented using the rule set included in the table of figure

2. The rule set includes four rules. The first rule “RULE 17 is a default rule which is pre- programmed but this rule will never be applicable in the present case, as RULE 2 has a higher priority and no condition requirement set. RULE 2 defines that the light level is 100% with a priority indication of 131. RULE 3 has a higher priority indication of 132, has a condition that the time has to be between 7 pm and 5 am, and has a control output putting the light level on 70%. Thus, between 7 pm and 5 am, the control output of RULE 3 will be applied as RULE 3 has a higher priority than RULE 2. RULE 4 has a higher priority indication of 133, has a condition that the time has to be between 5 am and 12 am, and has a control output putting the light level on 40%. Thus, between 5 am and 12 am, the control output of RULE 4 will be applied as RULE 4 has a higher priority than RULE 2.

In the example of figure 2, the control output includes only a light level. However, additionally or alternatively the control output may include any other light related output for controlling the light module 200, such as a light temperature, a light colour, a light pattern.

The example of figure 2 relates to the controlling of a light module. However, also other luminaire components 200° may be controlled. The control output for such other luminaire components may comprises an output indicating whether the luminaire component has to be switched on or off. For example, the other luminaire component could be a camera which needs to be switched on under certain conditions or a plant Hrigation means which needs to be triggered when certain conditions are fulfilled. Using a plurality of rules, as defined above, also such other luminaire components can be controlled in a structured and flexible manner.

In the example of figure 2 only the time is used as an input. Additionally or alternatively, the one or more inputs I, I’, I” may comprise any one or more of the following: sensor data, such as light sensor data, motion/presence detection data, an angle of the sun, an input for indicating an emergency, a pollution related input, a weather related input, an energy consumption related input, etc. To that end, the luminaire controller may be provided with the one or more measurement devices 300, 300°, 300” as described above.

Figures 3-5 illustrate some further examples of possible rule sets. In the example of figure 3, RULE 1 is identical to RULE 1 of the example of figure 2. RULE 2 has a higher priority indication than RULE 1 and sets a light level of 0, i.e. the light module will be switched off when this rule is applicable. RULE 3 has an even higher priority indication of 132, has a condition that a sensor value has to be higher than a threshold, and has a control output putting the light level on 40%. Thus, when the sensor value is higher than the threshold, the control output of RULE 3 will be applied as RULE 3 has a higher priority than RULE 2. The sensor may be e.g. a movement sensor, and RULE 3 may thus be applicable when movement is detected.

In the example of figure 4, RULES 1 and 2 are identical to the RULES 1 and 2 of the example of figure 2. RULE 3 has a higher priority indication of 134, has a condition that the angle o of the sun and the time have to fulfil certain conditions (e.g. higher than -3° for sunset, i.e. after 12 am, and higher than -2,5° for sunrise, i.e. before 12 am; in other words in this example ol is 2,5° and a2 is 3°), and has a control output putting the light level on 0%. RULE 4 has a higher priority indication of 135, has a condition that the angle 0 of the sun has to be higher than 0°, and has a control output putting the light level on 0%. Thus, when the angle « of the sun is higher than 0°, the control output of RULE 4 will be applied as RULE 4 has a higher priority than RULE 2 and RULE 3.

When the angle o of the sun is between 0° and -3° after 12 am or between 0° and -2,5° before 12 am, the light level 0% is also applied. Thus, for certain angles Ot of the sun, the light module is switched off.

In the example of figure 5, RULES 1 and 2 are identical to the RULES 1 and 2 of the example of figure 2, with this difference that the light level of RULE 2 is 70%. RULE 3 has a higher priority indication of 134, has a condition that the date DATE has to correspond with a certain date (e.g. 25 December), and has a control output putting the light level at 45%. RULE 4 has a higher priority indication of 137, has a condition that the sensed movement SENSED MOVEMENT is higher than a threshold, and has a control output putting the light level at 70%. RULE 5 has a higher priority indication of 143, has a condition that the date DATE has to correspond with a certain date (e.g. 1 January), and has a control output putting the light level at 90%. RULE 6 has a higher priority indication of 149, has a condition that the angle « of the sun, the time t, the sensed light SENSED LIGHT, and a pre-set dimming level DIM LEVEL have to fulfil certain conditions (e.g. when the dimming level is not 0 and the angle a is higher than - al for sunrise, i.e. before 12 am, and when sensed light is higher than a threshold, RULE 6 applies, OR, when the dimming level is not 0 and the angle OQ is higher than - 022 for sunset, i.e. after 12 am, and when the sensed light is higher than a threshold, RULE 6 applies, OR, when the dimming level is 0, RULE 6 applies), and has a control output putting the light level on 0%. RULE 7 has a higher priority indication of 149, has a condition that the angle of the sun Ot has to be higher than 0°, and has a control output putting the light level at 0%. RULE 8 has a higher priority indication of 151, has a condition that the sensed light has to be higher than a threshold, and has a control output putting the light level at 0%. Figure 6 illustrates a further example for a luminaire system comprising irrigation means configured to irrigate plants.

The rule set uses as inputs a humidity value HUMIDITY from a ground humidity sensor; an angle « of the sun from an astronomical clock, a timer value TIME for switching on the irrigation means, and a manual command MANUAL CMD (REMOTE) for switching on the irrigation means, and provides as an output a switch level signal SWITCH LEVEL for activating the plant irrigation.

RULE 1 is a default rule with a priority level of 128 which sets the switch level signal in an OFF state.

RULE 2 has a higher priority level of 130, and has a condition that if the humidity value HUMIDITY is below a predetermined setpoint and if the angle « of the sun is below 0° in the evening, and if the timer value TIME is larger than 0, the switch level signal will be triggered in an ON state for a period of time corresponding with the timer value provided as an input, e.g. 10 Minutes.

RULE 3 has an even higher priority level of 131, and switches on the irrigation means based on a manual command from a remote city management system MANUAL CMD (REMOTE). In that way a manual command from a remote city management system can oversteer at any time, i.e. the manual command will be decisive in that case.

Figure 7 illustrates a further example for a luminaire system comprising a camera.

The rule set uses as inputs a motion value MOTION from a motion sensor, and a hold-timer value HOLD TIMER, and provides as an output a relay trigger value CAM RECORD TRIGGER to enable the camera to record for period of time.

RULE 1 is a default rule with a priority level of 128 which sets the relay trigger value CAM RECORD TRIGGER in an OFF state.

RULE 3 has the highest priority level of 135, and has a condition that if the motion sensor is triggered (i.e.

MOTION = TRUE), the relay trigger value

CAM RECORD TRIGGER will be triggered in an ON state. RULE 2 has a priority level of 134, and makes sure that the camera remains triggered in an ON state, even if the motion sensor is no longer sensing motion (MOTION = FALSE) as long as the hold-timer provided as an input is larger than 0.

It is noted that the same input may be used in different rule sets. For example, the motion value MOTION may be used to trigger the camera and to increase the light level. In that regard it is noted that the “SENSED MOVEMENT > THRESHOLD” condition of figure 5 may be the same as the “MOTION = TRUE” condition of figure 7. Further it is noted that multiple rule sets may be IO operating in parallel to control different luminaire components. The luminaire controller 100 comprises storage means for storing one or more rule sets. In a further developed embodiment, each rule set may be associated with a rule set priority indication, and the control means may be configured to control the laminaire component in accordance with i5 the rule set with the highest rule set priority indication. sE This is illustrated with an example in the table above. In this example, three rule sets RSI, RS2, RS3 are stored. The rule set may be as defined above. E.g. rale set RSI may correspond with the rule set of figure 2, RS2 with the rule set of figure 3, and RS3 with the rule set of figure 4. RS3 has the highest priority, so this rule set will be used by the luminaire controller. In that manner, it is possible to switch between rule sets by changing the rule set priority of a rule set. This provides an additional degree of flexibility to the implementation of different rules. According to non-illustrated embodiments the invention relates to a computer program configured for providing a user interface to a user allowing a user to enter, for each rule of a rule set with a plurality of rules, the following information: - a priority indication, - at least one control output, - an optional condition requirement for at least one input, The computer program is further configured for generating a code for said rule set based on said information, and for sending said code for said rule set to a luminaire controller 100. In other words, the code for a rule set may be prepared on a user interface device, such as a remote server or mobile device 2000, and this code may be transmitted to the luminaire controller 100 via a network 3000, see figure 1 In a possible embodiment, all luminaire controllers are configured to communicate directly over a cellular network. However, in other embodiments, the luminaire network system comprises a plurality of luminaires 1000 and an edge system. The edge system may be a luminaire, or may be a device which only comprises an edge luminaire controller. The latter is often called a segment controller. The luminaire controllers 100 may then be configured to transmit the plurality of messages to the edge luminaire controller using an IEEE 802. 15.4-based protocol, such as a Zigbee protocol. In that case, the luminaire controllers 100 will be configured to transmit data to the edge luminaire controller using a wireless personal area network (WPAN), preferably as defined in the IEEE 802.15.4 standard. In that manner, the luminaire controllers 100 may communicate with each other as in a mesh network, whilst the edge luminaire controllers may additionally communicate with a remote device 2000 through the cellular network.

A person of skill in the art would readily recognize that steps performed by the luminaire controller or by the edge luminaire controller or by the remote device or mobile device can be performed by programmed computers. Herein, some embodiments are also intended to cover program storage devices, e.g., digital data storage media, which are machine or computer readable and encode machine-executable or computer-executable programs of instructions, wherein said instructions perform some or all of the steps. The program storage devices may be, e.g., digital memories, magnetic storage media such as a magnetic disks and magnetic tapes, hard drives, or optically readable digital data storage media. The embodiments are also intended to cover computers programmed to perform said steps.

The functions of the various elements shown in the figures, including any functional blocks labelled as “controllers” or “control means”, may be provided through the use of dedicated hardware as well as hardware capable of executing software in association with appropriate software. When provided by a processor, the functions may be provided by a single dedicated processor, by a single shared processor, or by a plurality of individual processors, some of which may be shared. Moreover, explicit use of the term “controller” or “control means” should not be construed to refer exclusively to hardware capable of executing software, and may implicitly include, without limitation, digital signal processor (DSP) hardware, network processor, application specific integrated circuit (ASIC), field programmable gate array (FPGA), read only memory (ROM) for storing software, random access memory (RAM), and non volatile storage. Other hardware, conventional and/or custom, may also be included. Similarly, any switches shown in the FIGS. are conceptual only. Their function may be carried out through the operation of program logic, through dedicated logic, through the interaction of program control and dedicated logic, or even manually, the particular technique being selectable by the implementer as more specifically understood from the context.

Whilst the principles of the invention have been set out above in connection with specific embodiments, it is to be understood that this description is merely made by way of example and not as a limitation of the scope of protection which is determined by the appended claims.
