Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
With the development of intelligent control technology, the lighting function of the lighting device is also extended wirelessly, for example: the lighting equipment can be switched on and off at fixed time, and the switching time of the lamp can be flexibly adjusted according to seasons and seasons; the lighting equipment has intelligent characteristics, can be combined with the illumination sensor technology, and can be automatically turned on in special weather (such as rainstorm and cloudy days); the lighting device can adjust light, automatically adjust to the maximum illumination when the flow of people is large, and automatically dim when the flow of people is rare or nobody exists.
The intelligent lighting control system composed of the intelligent controllable lighting equipment can enable the lighting effect of each lamp in the lighting system to be more beautiful and the lighting to be more intelligent, and the management of the light is more scientific. However, there are many implementation methods when the intelligent control of the lighting system is implemented, but most lighting devices are independently controlled and have no negotiation process, so that there is a difference in the overall lighting control effect of the lighting system.
In the conventional lighting control system, the sensor is controlled separately from the lighting module, and the change of the area of each lighting device cannot be accurately performed. For example, the illuminance sensor is disposed near the window to control a row of lighting lamp panels near the window, but the sensor is located at a position where the lighting position of the same light is controlled as much as possible when the sensor is disposed, but the more the lighting devices are controlled, the more obvious the lighting difference between different devices is, which is the worst experience part in practical application. The part controlled by the dynamic and static sensors can respond only when people reach the position of the sensors, the range of the controlled lighting equipment is generally much larger than the detection range of the sensors, so that the controlled lighting equipment cannot respond in time, the control area has no better light grading control, and the comfort level and the energy conservation are further improved.
The characteristics of the illumination deployment area are generally complex, such as an aisle, a corridor, a toilet, a front desk and the like, the scene processing through intelligent control is often complex, the illumination requirements of different areas are different, and the energy-saving targets are actually different.
In view of the foregoing problem, an embodiment of the present invention provides a lighting control system, and fig. 1 is a schematic structural diagram of a lighting control system according to an embodiment of the present invention, and as shown in fig. 1, an intelligent control system according to an embodiment of the present invention may include a plurality of lighting nodes 100 that can communicate with each other, where a wireless master control device 110, a driving device 120 connected to the wireless master control device 110, and at least one lighting unit 130 controlled by the driving device 120 may be disposed in the lighting nodes. The wireless master control device 110 is configured to detect the brightness of the current environment when detecting that a user exists within a specified range from the lighting node to which the wireless master control device belongs; the wireless master control device 110 is further configured to define a lighting scene for the lighting node based on the environment attribute of the lighting node to which the wireless master control device 110 belongs, adjust an output parameter of the driving device 120 in the lighting node according to the brightness of the current environment and the lighting scene currently defined by the lighting node, and control the lighting brightness of the lighting unit 130; and sends a light-up instruction to other lighting nodes of the lighting control system. The output parameter of the driving device 120 may be a brightness, a color temperature, etc. parameter of the lighting unit.
Preferably, the wireless master control device 110 may be preset with at least one lighting scene, and when defining a lighting scene for its belonging lighting node, one lighting scene may be selected from the at least one lighting scene as the lighting node lighting scene based on the environmental attribute of its belonging lighting node. For example, the lighting nodes may be disposed in a living room, an aisle, a corridor, a toilet, a front desk, etc., and different lighting scenes, such as safety lighting, night lighting, unmanned lighting, aisle lighting, etc., may be defined for the lighting nodes according to their actual environmental attributes.
Further, the wireless master control device 110 may also be configured to receive a light-up instruction sent by another lighting node in the lighting control system to the lighting node to which the wireless master control device 110 belongs, and adjust the lighting brightness of the lighting node according to the light-up instruction.
The embodiment of the invention provides a more flexible lighting control system, wherein the wireless main control equipment 110 is arranged in each lighting node 100 of the lighting control system, the environment near the lighting node is detected through the wireless main control equipment 110, the lighting brightness of the lighting node is adjusted to the optimal lighting state according to the detection result and the lighting scene currently defined by the lighting node, and a lighting instruction is sent to other lighting nodes in the lighting control system. In addition, the wireless master control device 110 may also receive a lighting instruction sent by another lighting node to the lighting node, and then the lighting instruction adjusts the lighting brightness of the lighting node.
In this embodiment, each lighting node 100 in the lighting control system may be a lighting device that works independently and is provided with the wireless master control device 110, the driving device 120 and the lighting unit 130, such as a lighting lamp independently installed in a living room or a bedroom; or the lighting nodes provided with a plurality of lighting units 130 may be controlled by one wireless main control device 110 and one driving device 120, for example, three spot lights in the foreground position are controlled by only one switch, so that the three spot lights as three lighting nodes can share one wireless main control device and one driving device, and the driving device automatically adapts to the loads of a plurality of LEDs. For example, for a ceiling lamp, the single wireless master device 110, the single driving device 120, and the one or more lighting units 130 controlled by the same driving device may be powered by a battery, or the one or more lighting units 130 may be controlled by a power supply through a wire, wherein the lighting units 130 may be spot lights, or the like.
The wireless master control device 110 may be a chip that integrates a wireless propagation function (such as bluetooth, WiFi, or ZigBee) and a logic processing function (such as a single chip microcomputer) at the same time. The driving device 120 provides power required for illumination to the entire illumination node 100, and converts the power voltage into an operating voltage required for the illumination node 100. The driving device 120 may be set according to different practical situations, such as constant current driving and voltage stabilization driving, which is not limited in the present invention. The driving device 120 in this embodiment supports a driving capability of a single lamp or multiple lamps, and can supply power to the wireless main control device 110 at 5V in practical application by plugging and unplugging the R, G, B, W, CW cable.
As introduced above, the wireless master device 110 may also combine the lighting scenes currently defined by its belonging lighting node when controlling the output parameters of the driving device 120 in its belonging lighting node. The lighting scene is related to the actual area where the lighting node is located, such as an aisle, a corridor, a toilet, a front desk and the like, and different scene modes are configured for different areas, such as safety lighting, wall washing lamps, night lighting, unmanned lighting, aisle lighting and the like. Preferably, the driving device 120 may be an automatically adaptable output load, which may also perform status, measurement and feedback of electrical quantities, fault detection, etc. Further, the driver device 120 may also power the wireless master device 110. The lighting unit 130 may have various forms, and a substrate and a light source may be provided in the lighting unit 130. When the lighting unit 140 is a ceiling lamp, it may include a chassis, a mask, and if it is a spotlight, it may include a base, a reflector, and a face ring, etc.

In practical application, the lighting instruction may carry a controlled target lighting node or a target lighting area, when the wireless master control device 110 in the controlled lighting node in the system receives the lighting instruction sent by another lighting node, the instruction may be analyzed to determine whether the lighting node or the lighting area to which the wireless master control device belongs is consistent with the target lighting node or the target lighting area in the lighting instruction, and when the lighting node or the lighting area to which the wireless master control device belongs is consistent with the target lighting node or the target lighting area in the lighting instruction, the lighting brightness of the lighting node to which the wireless master control device belongs is adjusted, preferably, the output parameter of the driving device in the lighting node to which the wireless master control device belongs is adjusted, so as.
Further, the wireless master control device 110 may be further configured to receive a light-up instruction sent by another lighting node in the lighting control system to the lighting node to which the non-wireless master control device belongs, and forward the light-up instruction. That is to say, the wireless main control device disposed in the lighting node 100 may receive a lighting instruction sent by any other lighting node, and after receiving the lighting instruction, determine whether the received lighting instruction is a lighting instruction for the lighting node to which the lighting instruction belongs (whether the lighting node sending the lighting instruction and the lighting node to which the lighting node belongs belong to the same lighting partition or other conditions), if the received lighting instruction is a lighting instruction for the lighting node to which the lighting node belongs, adjust the lighting brightness of the lighting node according to the lighting instruction, and if the received lighting instruction is not a lighting instruction for the lighting node to which the lighting node belongs, forward the lighting instruction.
As shown in fig. 2, the lighting control system according to the embodiment of the present invention may further include a configurator 200 configured with a preset matrix map, where the configurator 200 may establish a wireless connection with each lighting node in the lighting control system.

In addition, the intelligent control system can also send a brightness instruction to other illumination nodes to realize interconnection of the illumination nodes, flexibly control working states of different illumination nodes according to the positions of users, and enable intelligent control of the illumination nodes to be more flexible, accurate and energy-saving.
Further, after the step S504, the method may further include a step S508 of receiving a lighting instruction sent by another lighting node in the lighting control system to a lighting node other than the lighting node to which the wireless master control device belongs, and forwarding the lighting instruction. That is to say, the wireless main control device may receive a lighting instruction sent by any other lighting node, and after receiving the lighting instruction, may determine whether the received lighting instruction is a lighting instruction for the lighting node to which the lighting instruction belongs (whether the lighting node sending the lighting instruction and the lighting node to which the lighting node belongs belong to the same lighting partition or other conditions may be determined), and if the received lighting instruction is a lighting instruction for the lighting node to which the lighting node belongs, adjust the lighting brightness of the lighting node according to the lighting instruction, and if the received lighting instruction is not a lighting instruction for the lighting node to which the lighting node belongs, only forward the lighting instruction.
Optionally, the lighting control system may further include a configurator configured with a preset matrix map; the configurator may establish a wireless connection with each lighting node in the lighting control system. The lighting control method provided by the embodiment may further include:
step S1, the configurator identifies the lighting area of the lighting control system, and after the arrangement of each lighting node in the lighting control system is completed, the lighting control system is divided into a plurality of independent lighting subareas according to the actual area division;

The brightness instructions may be forwarded between different lighting zones, but not perform their own lighting output. When the matrix coordinates corresponding to each lighting node are transmitted to each lighting node, the matrix coordinates of each lighting node in the same lighting partition may be generated. The configurator may perform transmission one by one, or may perform transmission directly after generating the matrix coordinates of each lighting node, which is not limited in the present invention.
The step S2 may further include, when generating the matrix map for any lighting partition: selecting any lighting subarea, establishing communication connection with any lighting node in the lighting subarea, and deploying the lighting node serving as a matrix coordinate origin point into a preset matrix diagram; and sequentially carrying out communication connection with other lighting nodes in the lighting subarea, deploying the other lighting nodes into a preset matrix diagram according to the actual positions, and generating and recording matrix coordinates for the other lighting nodes.
Preferably, the method may further include step S5, if the configuration of the matrix coordinates of each lighting node is completed, generating a matrix map with each lighting node in the lighting partition as a matrix element based on the matrix coordinates of each lighting node in the lighting partition; and transmitting the matrix map to each lighting node, and storing the matrix map by the wireless master control equipment of each lighting node. The preset matrix map can be preferably a two-dimensional matrix; the configurator is preferably a mobile terminal. After the matrix map of the lighting partition is generated, the matrix map can be uniformly transmitted to each lighting node and stored by the wireless master control device of each lighting node.
Fig. 6 is a flowchart illustrating a method for generating a matrix map of any lighting partition by a mobile terminal according to an embodiment of the present invention, and as shown in fig. 6, the method for generating a matrix map of a lighting partition according to the present invention may include:
step S602, firstly, identifying an illumination area covered by an illumination control system, partitioning after the illumination nodes are deployed, and respectively performing matrix configuration on each illumination partition; such as open office areas, aisles, front desks, closed meeting rooms, etc.; each area light source does not influence the control of other areas; after each lighting node is powered on, the light source is defaulted to be undeployed, so that beacon signals can be broadcasted with low power consumption after each lighting node is powered on, and connection confirmation of the mobile terminal is waited;
step S604, when matrix deployment is carried out on any lighting partition, lighting nodes at corners in the lighting partition are selected as coordinate origin points of a matrix map and are deployed into a preset empty two-dimensional matrix map; the other lighting nodes in the lighting subarea are approached, the lighting nodes are correspondingly arranged in a matrix graph according to the actual positions of the lighting nodes with the origin of coordinates after one lighting node is obtained every time, the matrix coordinates are generated and recorded, and then the matrix coordinates are transmitted to the corresponding lighting nodes and are stored by the wireless master control equipment of each lighting node;
step S606, confirming whether the matrix coordinates of each lighting node in the lighting subarea are correct; if not, that is, the coordinate information is wrongly written, then the configuration needs to be re-performed within a short time after power-on, step S604 is repeated, and if yes, step S608 is executed;
step S608, determining whether the lighting nodes in the lighting partition are deployed, if not, repeating steps S604 to S606, and if yes, performing step S610;
step S610, after the matrix coordinates of all the lighting nodes in the lighting subarea are generated and correct, storing and recording the matrix coordinates in the mobile terminal; the matrix map of the illumination zones may be as shown in fig. 7;
step S612, transmitting the matrix map including the matrix coordinates of each lighting node to each lighting node, and completing the generation of the lighting partition matrix map.
The matrix map of each lighting partition may be not only a two-dimensional matrix map, but also a one-dimensional coordinate, such as a node of an aisle or a corridor; but also includes a single point, such as an independent light source node of a security exit or a wall washer, etc., and the present invention is not limited thereto.
In step S604, after the matrix coordinates of the lighting nodes are generated, only the matrix coordinates of each lighting node may be recorded locally, and after all the matrix coordinates of each lighting node in the whole lighting partition are generated, the coordinate information is transmitted to each lighting node through the wireless network in a unified manner.
The method provided based on the above embodiment can perform matrix configuration on each lighting partition in the lighting control system, and further generate a matrix map. After the configuration of the matrix of each lighting partition is completed, each matrix actually corresponds to different functional areas, corresponding scene collaborative matrix calculation control needs to be selected, and each lighting node defaults to have a plurality of common scenes, such as safety lighting, wall washing lamps, night lighting, unmanned lighting, aisle lighting and the like. After each lighting node is physically powered on, beacon broadcast packets can be transmitted at low power within a period of time, the configurator obtains the MAC address of each lighting node through proximity induction, meanwhile, corresponding matrix coordinates are transmitted to the lighting nodes, and the lighting nodes are restarted to enter a normal working mode after configuration is completed. And if the connection control of the configurator is not received within a certain time, entering a factory configuration mode. Each lighting partition is a two-dimensional matrix image after the matrix is deployed, and the matrix can be large or small.
In an embodiment of the invention, the defining of the lighting scene for each lighting zone is based on a matrix approach for the control application. Each lighting node has a common default scene setting, only a scene number needs to be selected, and each scene is formed by the following single scene control parameter or the combination of the scene control parameters. Therefore, after transmitting the matrix map and the matrix coordinates corresponding to each lighting node, the method may further include: setting one or more lighting scenes for the lighting nodes in each lighting subarea based on the attribute function of each lighting subarea and preset scene control parameters, and distributing scene numbers for the lighting scenes; wherein the scene control parameters include a plurality of brightness levels for each lighting node and a duration of each brightness level.
Preferably, as shown in fig. 8, the scene control parameters may include:
1. the maximum brightness Level (Maxlum Level) refers to the maximum brightness within a specified range from the lighting node until the presence of a user. In general, the illumination brightness of the new illumination node is generally not 100%, but about 80%; considering that the long-term use of the lighting node may cause the light of the LED to be degraded, the brightness level may be automatically increased to maintain the maximum brightness level if the brightness of the lighting needs to be maintained.
In addition, in consideration of balance between comfort and energy conservation, natural light compensation in daytime is performed, and the actual brightness of the LED with insufficient natural light is corrected by taking 80% as a target. For example, when the current 640lux is used, the target needs to be adjusted to 320lux, the target can be adjusted to 340 (5-10%) for the first time, then each region is independently fine-tuned, and the small region approaches until the satisfaction is reached;
2. a maximum brightness duration (Holdingtime) which is a holding time of a maximum brightness level when a user exists; if the wireless main control equipment does not detect the existence of the user within a certain time, the wireless main control equipment is switched to a stable low brightness level, and the brightness is automatically reduced to save energy. This time may be 10 seconds to 60 minutes, default to 10 minutes, to achieve a balance of energy saving and comfort.
3. A stable low brightness Level (lowum Level) which is a lighting Level that is maintained within a specified range from a lighting node regardless of the presence of a user; such as safety lighting, whether someone is required to maintain a non-zero level; when no person is in the passage at night, the brightness level is 10 percent; the unmanned elevator room or the elevator room after work also needs to be automatically maintained;
4. a steady low brightness duration (Lowlum Time), which refers to the hold Time before the light is completely turned off; default to 10 minutes;
5. a minimum brightness Level (minimum Level), which is the lowest brightness when the lighting node does not provide the lighting service; i.e. the lowest brightness for complete lamp shut-down, is substantially 0; when the duration time of the stable low brightness is reached, the illumination node can be automatically in a closed state, manual physical power-off and light-off in the off-duty time are not needed, and the time of a user is saved.
Through the scene control parameters, the lighting service can be automatically provided for the user according to the needs of the user under the condition that the user does not need to manually participate, and the user experience is further improved.
The above-mentioned scene control parameters may be combined to suit different lighting scenes and different lighting functions, such as closed meeting rooms, toilets, locker rooms, aisles, open office areas, etc. The scene control parameters are listed schematically, and in practical application, other scene control parameters can be set according to requirements to perform custom definition on a new lighting scene.
Preferably, the wireless master device in each lighting node may include: the system comprises a main controller, a first sensor and a second sensor, wherein the first sensor and the second sensor are connected with the main controller; the step S502 may further include: when a second sensor in the wireless master control equipment of any lighting node in the lighting system detects that a user exists in a specified range, a detection signal is transmitted to the master controller, the first sensor detects the brightness of the current environment, and the brightness of the current environment is converted into readable illumination data to be transmitted to the master controller; the step S504 may further include: and receiving readable illumination data transmitted by the first sensor and/or a detection signal transmitted by the second sensor by the main controller, and adjusting the illumination brightness of the illumination node to which the illumination node belongs based on the readable illumination data and/or the detection signal and the illumination scene currently defined by the illumination node. Alternatively, the first sensor 112 is preferably an illuminance sensor, and the second sensor 113 is preferably a dynamic-static sensor.
In the embodiment of the invention, the illumination sensor is combined with the illumination node, only the illumination of the node is corrected, and other illumination nodes in the illumination subarea are not controlled, so that the illumination node is more comfortable, and the effect influence caused by different positions such as a window, a wall and the like is greatly reduced. And through combining sound sensor and illumination node, make every illumination node all can in time, respond to user's existence fast, through the distance between the illumination node, can select the infrared sound sensor of the hot spot of suitable detection scope.
After the step S5023, a lighting instruction may also be sent to other lighting nodes of the lighting control system, where the lighting instruction carries the matrix coordinates of the lighting node to which the main controller belongs. In practical applications, when it is detected that the lighting nodes existing in the user independently provide the lighting brightness, the lighting effect is not ideal. In the above embodiment, after detecting that a user is present, the lighting node may send a lighting instruction to other lighting nodes, and the other lighting nodes assist in lighting.
In step S504, if the wireless main control device receives the lighting instruction sent by another lighting node, the lighting brightness of the lighting node to which the wireless main control device belongs may be controlled based on the lighting instruction. It may further comprise:
step S5041, if the main controller receives the lighting instructions sent by other lighting nodes, acquiring the matrix coordinates of the lighting nodes sending the lighting instructions;
step S5042, when the lighting node sending the lighting instruction and the lighting node to which the lighting node belongs belong to the same lighting partition, calculating the distance between the lighting node sending the lighting instruction and the lighting node to which the lighting node belongs;
step S5043, calculating a required brightness level of the lighting node based on the distance and the lighting scene currently defined by the lighting node, and adjusting the lighting brightness of the lighting node based on the brightness level.
In this embodiment, each lighting node serves as a master control to send a lighting instruction, and each lighting node includes its own matrix coordinate, except for its lighting output, the lighting nodes in the same area receive the lighting instruction, and calculate the distance according to its own coordinate, thereby calculating the output parameters of its own lighting node according to its respective currently defined lighting scene. If a plurality of lighting instructions are received, the output is executed according to the latest lighting instruction after calculation
The intensity level of a lighting node is related to the distance of the lighting node where the light command occurred. If a dynamic and static sensor of an illumination node detects that a user exists in the designated range, the illumination node closest to the user (namely the illumination node to which the dynamic and static sensor belongs) is 100% of the maximum output, and the brightness levels slightly far away are sequentially changed into 70%, 40%, 10% and 0, so that the light of the area where people are located is always kept in the most comfortable state, the far away light has little influence on people, and the illumination output can be reduced by saving energy. Each brightness level can be adjusted according to the actual application environment, and the invention is not limited.
Further, the above embodiment may further include step S5044, where if the main controller receives a light-on instruction sent by the multiple lighting nodes, the main controller obtains matrix coordinates of the multiple lighting nodes, respectively calculates distances between the lighting nodes belonging to the same lighting partition as the lighting node belonging to the lighting node, and ranks the calculated distances;
step S5045, calculating a brightness level required by the lighting node according to the shortest distance and the lighting scene currently defined by the lighting node, and adjusting the lighting brightness of the lighting node based on the brightness level.
When a plurality of users are in different positions in an application scene, a plurality of lighting nodes can simultaneously send a lighting instruction, and when the lighting nodes which do not detect the users simultaneously receive the lighting instructions, the lighting instruction sent by the lighting node closest to the lighting nodes is used as the standard, so as to assist in lighting.
The method provided by the embodiment of the invention can also automatically adjust the illumination brightness under the condition that no new light-on instruction is provided. Namely, the method may further include: and if the duration of the current brightness level of the lighting node to which the main controller belongs does not receive a new light-on command after the duration reaches the preset time, controlling the lighting node to switch to the next level of lighting brightness required by the currently defined lighting scene.
In addition, the lighting control system can also comprise a relay node which establishes wireless connection with each lighting node in the lighting control system; if the relay node receives any light-up instruction, the light-up instruction is forwarded; the relay node is preferably a wireless master control device. For example, in some field deployments where lighting is not required but where enhanced transmission of wireless signals is required, such as in a closed conference room or in a corner where attenuation or blockage of wireless signals may occur, the switching may be performed by the separate module.
The following is a detailed description of a specific embodiment. Fig. 9 is a flowchart illustrating a lighting control method according to an embodiment of the present invention, and as shown in fig. 9, the lighting control method according to an embodiment of the present invention may include:

step S904, if the lighting node is in the daytime, the luminance of the current environment is detected by the illuminance sensor, the data converted into readable data is transmitted to the main controller, and the main controller corrects the driving output of the lighting node by combining the compensation of natural light;
step S906, sending a lighting instruction carrying the matrix coordinate of the lighting node;
step S908, other lighting nodes receive the lighting instruction with the matrix coordinate, if the lighting node sending the lighting instruction is judged to be the same lighting subarea, the distance from the lighting node to the sending node is calculated, and the distance is calculated according to the optimal path algorithm;
coordinates of master control point (lighting node sending lighting instruction): (x0, y0)
Controlled point coordinates (lighting nodes receiving light-up instructions): (xi, yi)
Distance grade: d ═ x0 (xi-x0) + (yi-y0)
Step S910, calculating the brightness level required by the lighting node by other lighting nodes according to the calculated distance and the currently defined lighting scene, and switching to a new brightness level;
step S912, when the lighting node does not receive a new command after the maintaining time of the current brightness level is reached, switching to the next brightness level required by the current lighting scene;
the data of the lighting scene are for example as follows:
Maxlum＝100
Holdingtime＝10min
Level1＝100％，level2＝70％，level3＝40％，level4＝10％，level5～＝10％
Lowlum＝10％
Deep＝0％
LowlumTime＝10min
and obtaining corresponding target grade data according to the calculated distance. If a new command is received at a more recent level, a switch is made to the new level immediately, and if it is a dimming, the waiting duration is decreased slowly to the next level. The scene is suitable for a general commercial office environment, when a node detects a person, the maximum output of the nearest lamp node is 100%, and the sequential brightness change at a distance of a little far away is 70%, 40%, 10% and 0, so that the light in the area where the person is located is always in the most comfortable state, and far away has little influence on the person, thereby saving energy and reducing the illumination output.
