It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.

Fig. 1 shows a schematic structural diagram of a coordinated control system for dimming areas according to an embodiment of the invention. The dimming area cooperative control system comprises a lighting assembly 11, a sensing assembly 12 and a control module 13.

The lighting assembly 11 comprises a plurality of lighting lamp groups located in different lighting areas; the sensing assembly 12 includes a plurality of illuminance sensors disposed in different illumination areas for detecting illuminance values of the illumination areas; the control module 13 establishes communication connection with the lighting assembly 11 and the sensing assembly 12 respectively; the sensing component 12 transmits the illuminance values of the different illumination areas detected by the sensing component to the control module 13, so that the control module adjusts the illuminance of the different illumination areas according to a preset illuminance value under the condition that the ambient illuminance and/or the illuminance of the adjacent illumination areas are overlapped.

It should be noted that, the control module 13, the sensing assembly 12 and the lighting assembly 11 may be communicatively connected through an integrated communication module, and the communication mode includes a wireless communication connection and a wired communication connection, for example: a bluetooth communication module, a WiFi communication module, a mobile network communication module, a ZigBee communication module, an NB-IoT communication module, or a MavLink communication module, etc., which is not limited in this embodiment.

Specifically, each lighting lamp group in the lighting assembly 11 includes at least one lighting lamp including, but not limited to, one or more combinations of ceiling lamps, wall lamps, spot lamps, desk lamps, floor lamps, classroom lamps, building lamps, and mining lamps. The control module 13 may be a separately established hardware processing element, or may be implemented by hardware devices such as a system-on-a-chip (SOC) integrated on the chip, and has a signal processing capability. The control module includes, but is not limited to, a Central Processing Unit (CPU), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component, and the like.

The lighting lamp groups may be grouped according to rules such as lighting areas and layout manners, for example: setting the lighting lamps divided into the same lighting area as the same lighting lamp group; or, the same row of lighting lamps transversely arranged in the indoor lighting lamp are set as the same lighting lamp group; or, the same row of lighting lamps longitudinally arranged in the indoor lighting lamps are set as the same lighting lamp group. The control module 13 can uniformly regulate and control the illuminance adjustment of the whole lighting lamp group in groups, and can also separately and respectively regulate and control the illuminance adjustment of one or more lighting lamps in the lighting lamp group, and each lighting lamp completes the illuminance compensation of the lighting area under the regulation and control of the control module.

For convenience of understanding, the technical solution of the present invention is further explained below with reference to a flow chart of adjusting the dimming area cooperative control system shown in fig. 2 and a schematic diagram of an indoor environment layout shown in fig. 3.

In this embodiment, three groups of lighting assemblies are disposed in an indoor environment of a restaurant, where the three groups of lighting assemblies respectively correspond to three lighting areas, namely, a lighting area A1 near a window, a lighting area A2 in the middle, and a lighting area A3 near a wall, and a window near the lighting area A1 is greatly affected by changes of natural light sources and has uneven illuminance; the illumination of the illumination area A2 is less influenced by the change of a natural light source, but indoor spaces exist on two sides of the illumination area A2 and are influenced by light rays of the illumination lamp groups on the two sides; the wall surface is arranged on one side of the illumination area A3 close to the wall, the indoor space is arranged on the other side of the illumination area A3 close to the wall, the influence of the natural light source change is small, and the influence of the illumination lamp of the illumination area A2 can be realized.

The illumination sensors are respectively arranged on the roof of the restaurant corresponding to the illumination areas A1, A2 and A3, and each illumination sensor is used for detecting the illumination value of each indoor illumination area in real time and transmitting the illumination value of each illumination area to the control module.

When the light-dimming area cooperative control system in a restaurant is actually used, a preset illuminance value in the indoor environment of the restaurant is set firstly, a low-color-temperature light source is selected for restaurant illumination for creating a comfortable and relaxing atmosphere, the preset illuminance value is set to be 300lx, an indoor illuminating lamp set is turned on for indoor illumination, the illuminance sensors respectively perform illuminance detection on an illuminating area A1, an illuminating area A2 and an illuminating area A3, and the illuminance values of the illuminating areas are transmitted to the control module.

Specifically, the illuminance of the illumination area A1 mainly depends on the mutual superposition of the ambient light of the illumination area A1, the light of the lamp group 1, and the light of the lamp group 2; the illumination of the illumination area A2 mainly depends on the mutual superposition of the illumination area A2, the light of the lamp group 1, the light of the lamp group 2 and the light of the lamp group 3; the illuminance of the illumination area A3 mainly depends on the mutual superposition of the illumination area A3, the light of the lamp group 2, and the light of the lamp group 3.

Wherein, 1/N sensors are used for detecting the illumination values of different illumination areas in the room, and the sensors include but are not limited to an illumination sensor. The illumination sensor is preferentially arranged on an indoor wall/roof position, and besides collecting illumination values of different illumination areas in an indoor environment in real time, the illumination sensor can also collect color temperature and color rendering index of the illumination areas. In some embodiments, the illuminance sensors can be communicatively interconnected and share information. It is understood that by illumination value is meant in particular an illumination intensity value, illumination intensity being a physical term referring to the luminous flux of the received visible light per unit area, in Lux or lx, for indicating the intensity of the illumination and the amount of illumination of the surface area of the object.

In this embodiment, the actual usage process of the dimming area cooperative control system is as follows:

firstly, setting a preset illuminance value of an indoor space, and detecting the illuminance value of any illumination area (such as an illumination area A1); and if a difference value exists between the actually measured illumination value of the illumination area A1 and the preset illumination value, controlling and adjusting the illumination of the illumination area A1 according to the difference value until the illumination value of the illumination area A1 is equal to the preset illumination value.

Secondly, after the actually measured illuminance value of the illumination area A1 is consistent with the preset illuminance value, under the condition of superposing the illuminance of the illumination area A1, detecting the illuminance value of the illumination area A2 and correspondingly adjusting the illuminance value until the illuminance value of the illumination area A2 is equal to the preset illuminance value under the condition that the illumination area A1 maintains the preset illuminance value.

Finally, considering the mutual influence among the light sources of the lighting lamp groups in different lighting areas, when the lighting areas A1 and A2 are adjusted, the illumination superposition amount of the lighting area A3 needs to be considered, the illumination detection is carried out on the lighting area A3, the illumination value is adjusted, and after the adjustment is finished, whether the illumination of the working lighting area A1 and the lighting area A2 still meets the standard requirement or not needs to be verified again after the illumination is changed; and when more than three groups of lighting lamp groups exist, sequentially detecting the illuminance values of all the indoor lighting areas A3-AN by repeating the steps, and controlling the illuminance adjustment of the lighting areas until the illuminance values of all the lighting areas of the indoor environment exist.

In some examples, when the sensing component 12 detects that the illuminance value variation of the indoor environment exceeds a preset range, the control module 13 controls the lighting components 11 correspondingly to compensate the ambient illuminance variation, that is, to control an increase or a decrease of the luminous flux of the lighting fixture, so as to ensure that the lamp compensation range is not too large, so as not to cause flickering and discomfort, and to keep the indoor environment under a constant illuminance.

In some examples, the illuminance adjustment of the lighting area may be implemented by group dimming, that is, each lighting lamp group is used as a uniform dimming object, the dimming manner is simple, efficient and convenient, and the dimming level may be set to be stepless dimming between 0% and 100%, for example, 0%, 20%, 40%, 60%, 80%, 100%, and the like, which is not limited in this embodiment.

In some examples, the illuminance adjustment of the illumination area may be achieved by single-lamp dimming, that is, the illumination lamps in the illumination lamp group are respectively adjusted, one or more illumination lamps in the illumination lamp group may be dimmed, and the dimming level may also be set to be stepless dimming between 0% and 100%, for example, 0%, 20%, 40%, 60%, 80%, 100%, and the like, which is not limited in this embodiment.

In some examples, the dimming area cooperative control system further comprises a shading device, wherein the shading device is arranged at the incident position of the natural light source and is used for cooperatively adjusting the illumination of the dimming area by shading the natural light. The opening level of the shading device comprises full opening, full closing, half opening and the like, for example, the opening degree is adjusted by adjusting the light transmittance of the shading device, the full transmittance indicates that the shading device is fully opened, the semi-transmittance indicates that the shading device is half opened, the non-transmittance indicates that the shading device is fully closed and the like. Further, the shading device may be provided with a driving mechanism, and after the shading device receives the control signal sent by the control module, the driving mechanism acts to realize the opening level control of the shading device.

In some examples, the control module of the dimming area coordinated control system performs any one or combination of illuminance setting, lighting area setting, and lighting scene setting on the dimming area. It should be understood that the illumination setting refers to setting a preset illumination for the light-adjusting region; the illumination area setting refers to setting indoor illumination subareas and area illumination; the lighting scene setting means setting a lighting mode according to an actual usage scene, including but not limited to an atmosphere mode, a class mode, a projection mode, a class mode, a full-off mode, a constant illumination mode, and the like. For example, in a classroom lighting environment, a constant illumination mode is turned on, a preset illumination value is set to be 500lx, indoor lighting is divided into four lighting areas, and group dimming control can be performed on three of the lighting areas.

Taking the indoor layout shown in fig. 3 as an example, 5 groups of lighting lamp sets are arranged in a classroom, including three groups of classroom lighting lamp sets located in a learning area, which correspond to a lighting area A1 near a window, a lighting area A2 in the middle, and a lighting area A3 near a wall, respectively; the blackboard lighting device also comprises two groups of blackboard lamp groups positioned in a teaching area (blackboard lighting area), and the two groups of blackboard lamp groups respectively correspond to a lighting area A4 and a lighting area A5 on two sides of the blackboard.

In this embodiment, each classroom lighting lamp group is respectively provided with 3 classroom lamps which are longitudinally arranged in an indoor space and respectively correspondingly illuminate the lighting area A1, the lighting area A2 and the lighting area A3. The two blackboard illumination lamp groups are respectively provided with a blackboard lamp arranged near the blackboard and correspondingly illuminate an illumination area A4 and an illumination area A5. The beam of the classroom is provided with illumination sensors corresponding to the illumination areas respectively, and the illumination sensors are used for detecting the illumination values of the illumination areas in the room in real time and transmitting the illumination values of the illumination areas to the control module.

Preferably, the dimming area cooperative control system may set lighting area setting, lighting scene setting, lighting brightness, and the like when actually used, and the preset illuminance value in the classroom environment is preferably set to 500lx in consideration of the influence of indoor lighting on the eyesight of students. The indoor classroom lamp and the indoor blackboard lamp are started to carry out indoor illumination, each illumination sensor carries out illumination detection on an illumination area A1, an illumination area A2, an illumination area A3, an illumination area A4 and an illumination area A5 respectively, and transmits an illumination value of each illumination area to the control module, and the control module sequentially controls and adjusts all the illumination areas according to the difference value of the illumination value of each illumination area and a preset illumination value until the preset illumination value is maintained indoors at 500lx.

The present embodiment further performs mode setting for different illuminance modes, which is specifically as follows: in the class mode, the blackboard lighting lamp group and the classroom lighting lamp group are adjusted to the strongest dimming level; in the projection mode, the blackboard lighting lamp group is adjusted to the weakest dimming level, and the classroom lighting lamp group is adjusted to the weaker dimming level; in the class-room mode, the blackboard lighting lamp group is adjusted to the weakest dimming level, and the classroom lighting lamp group is adjusted to the stronger dimming level; under the constant illumination mode, the blackboard lighting lamp group and the classroom lighting lamp group are adjusted to the strongest dimming level. For example: in the class mode, the dimming level of the blackboard lighting lamp set is adjusted to be 100%, and the dimming level of the classroom lighting lamp set is also adjusted to be 100%; in a projection mode, adjusting the dimming level of a blackboard lighting lamp group to be 0% and adjusting the dimming level of a classroom lighting lamp group to be 20%; in the class-room mode, the dimming level of the blackboard lighting lamp group is adjusted to be 0%, and the dimming level of the classroom lighting lamp group is adjusted to be 60%; in the constant illuminance mode, the dimming level of the blackboard illumination lamp set is adjusted to 100%, and the dimming level of the classroom illumination lamp set is also adjusted to 100%. When the lighting system is in the constant illumination mode, the light dimming area cooperative control system detects the indoor actual illumination value in real time according to the light dimming area cooperative control adjusting method and adjusts the luminous flux of the lighting lamp group, so that the preset illumination value is always maintained in each lighting area and classroom, and the constant illumination lighting state is kept.

It is worth noting that in the existing indoor lighting of buildings, the situation that only one group of lighting lamp groups is turned on indoors rarely exists, and most of the lighting lamp groups are matched with a plurality of lighting lamp groups; moreover, even in the case of multiple lighting lamp groups, a single lighting lamp or a group of lighting lamp groups is adjusted without considering the influence of adjacent lighting lamp groups on the current lamp group. Therefore, when the control module performs illumination adjustment, the joint influence of two lighting lamp groups, three lighting lamp groups, or even N lighting lamp groups on different lighting areas needs to be considered. Because the illumination influence of the artificial light source on a certain working surface is simple linear superposition, when the combined illumination influence among different lighting lamp groups is calculated, only the illumination values at the position need to be added.

Fig. 4 is a flow chart illustrating a coordinated control method for dimming areas according to an embodiment of the invention. It should be noted that the coordinated control method for the dimming region of the present embodiment can be applied to various controllers, such as an ARM (Advanced RISC Machines) controller, an FPGA (Field Programmable Gate Array) controller, an SoC (System on Chip) controller, a DSP (Digital Signal Processing) controller, or an MCU (micro controller Unit) controller; the method can also be applied to some intelligent terminals, such as desktop computers, notebook computers, pad computers, smart phones, wearable intelligent terminals (such as smart bracelets, smart watches, smart helmets, etc.); the method can also be applied to a server, and the server executes the light dimming area cooperative control method and then issues corresponding lamp control instructions to the lighting lamp; the servers may be arranged on one or more physical servers according to various factors such as functions, loads, etc., or may be formed of a distributed or centralized server cluster.

In the present embodiment, the method for cooperatively controlling a dimming area includes steps S41 to S44, and the implementation process and principle of each step will be explained in detail below.

Step S41: an indoor space is divided into a plurality of illumination areas.

Step S42: and selecting any illumination area as a first illumination area for illumination value detection, and adjusting the illumination value of the illumination area according to a preset illumination value until the illumination value is consistent with the preset illumination value.

Step S43: and under the illumination superposition of the illumination areas with the adjusted illumination values, detecting the actual measurement illumination values of the adjacent illumination areas one by one, adjusting the actual measurement illumination values to be consistent with the preset illumination values according to the preset illumination values until the actual measurement illumination values of all the illumination areas in the indoor space are adjusted to be consistent with the preset illumination values.

It should be noted that, when detecting the illuminance value of the first illumination area, only the influence of the ambient light on the illuminance of the first illumination area needs to be considered, but when detecting the illuminance of other illumination areas, the influence of the illuminance of the adjacent area on the first illumination area needs to be considered, that is, the superimposed influence of the illuminance of the adjacent area needs to be considered.

Step S44: and starting to perform illumination detection and adjustment again from the first illumination area until the actually measured illumination value of the whole indoor space is consistent with the preset illumination value. It should be understood that, since the illuminance between the illumination areas may be overlapped and influenced, although the area where the illuminance adjustment is first completed is adjusted to the preset illuminance value, the illumination area that is adjusted later may adversely influence the illumination area that is first adjusted, so that after one round of illuminance adjustment is completed, one or more rounds of repeated adjustment may be required to achieve the brightness balance of the entire indoor space and the brightness balance may be consistent with the preset illuminance.

Taking A1-AN illumination areas in AN indoor space as AN example, the process of the coordinated control method for the dimming areas is as follows:

step A) presetting AN illuminance value X of AN indoor environment, and dividing AN indoor space into A1-AN lighting areas.

And B) selecting any lighting area as a first lighting area, for example, selecting the lighting area A1, detecting that the actually measured illuminance value of the lighting area A1 is X1, comparing the difference value between the illuminance value of the lighting area A1 and a preset illuminance value, and controlling and adjusting the illuminance of the lighting area A1 according to the difference value if the illuminance value is not equal to the preset illuminance value until the illuminance value of the lighting area A1 is equal to the preset illuminance value.

And C) detecting the illuminance value of an adjacent illumination area A2 of the illumination area A1 under the condition of superposing the illuminance of the illumination area A1, comparing the difference value between the illumination area A2 and a preset illuminance value, and controlling and adjusting the illuminance of the illumination area A2 according to the difference value if the illuminance value is not equal to the preset illuminance value until the illuminance value of the illumination area A2 is equal to the preset illuminance value under the condition that the illumination area A1 maintains the preset illuminance value.

And D) repeating the step C to sequentially detect the illumination values of all the indoor illumination areas A3-AN and control the illumination adjustment of the illumination areas until all the illumination areas of the indoor environment reach the preset illumination values.

And E) detecting the real-time illuminance value of the indoor environment, and repeating the steps B-D when the real-time illuminance value does not maintain the preset illuminance value.

In some examples, the dimming area cooperative control method further includes: and when the change amplitude of the ambient light illumination value in the indoor space is detected to exceed a preset amplitude value, carrying out corresponding illumination compensation on the lighting lamp group in the indoor space so as to ensure that the lamp compensation amplitude is not too large, avoid flickering and darkness and discomfort and enable the indoor environment to be in a constant illumination.

In some examples, adjusting the illumination values of different illumination areas to a preset illumination value (illumination compensation value) may be specifically implemented by establishing a mathematical algorithm model, for example, repeatedly learning and training the collected illumination values at different positions as input values of a neural network, obtaining a prediction model of the illumination values, predicting the illumination value of a certain indoor illumination area according to the illumination value prediction model, reversely predicting the illumination value of the illumination area to adjust to the illumination compensation value required by the preset illumination value according to the illumination value in the indoor environment collected in real time, generating a control signal by using the illumination compensation value as a target value, sending the control signal to the illumination assembly of the corresponding illumination area, allowing the illumination assembly to adjust its illumination state after receiving the control signal until the illumination area always maintains a preset constant illumination, sequentially detecting the illumination values of the illumination areas one by one and calculating the illumination compensation value according to the division of the illumination areas, and allowing all the illumination areas in the indoor space to maintain the preset illumination value.

In some examples, the dimming area cooperative control method further includes: and taking each lighting lamp group as a uniform dimming object, and dimming according to a preset dimming level. For example, the dimming level can be set to be stepless dimming between 0% and 100%, such as 0%, 20%, 40%, 60%, 80%, 100%, etc., and the dimming mode is simple, efficient and convenient.

In some examples, the dimming area cooperative control method further includes: the illuminance of the illumination area is adjusted by adjusting the illumination of one or more lighting fixtures in the lighting lamp group. For example, one or more lighting fixtures in the lighting lamp group may be dimmed, and the dimming level may be set to be stepless dimming between 0% and 100%, for example, 0%, 20%, 40%, 60%, 80%, 100%, etc., which is not limited in the present embodiment.
