Memory cell

In the present embodiment, the storage unit 40 is capable of acquiring the behavior of the light units 10 under the control of the single-lamp control unit 30 and generating a work log of the acquired behavior data, specifically, the behavior data of the light units 10 may be acquired according to actual usage requirements, and the work log includes ON-OFF, dimming, and toning information of each light unit 10 associated with a time and mapping information of a data channel in the first channel.

In the present embodiment, the storage unit 40 is in communication connection with the light unit 10, specifically, the storage unit 40 is a node in a mesh network, and thus, the data in the storage unit 40 can be called and used by any node in the mesh network, and the limitation on the setting position and the setting number of the storage unit 40 is removed, which may be set as multiple or one, and may be integrated in the light unit 10 or the group control unit 20, or may be set as one node independently, thereby saving the cost of constructing the lighting system and making the construction mode of the lighting system more diversified.

In the present embodiment, the storage unit 40 can also store control group information and scene information obtained by the processing unit 50 processing the work logs.

Processing unit

The processing unit 50 is communicatively connected to the storage unit 40 and the optical unit 10, specifically, the processing unit 50 is a node in a mesh network, and the processing unit 50 is capable of analyzing the working log, it should be noted that the processing unit 50 analyzes the working log based on a certain logic, and an operation logic of the working log is formulated according to a requirement of a user, and the following examples of the embodiment are not limiting on the operation logic of the present technical solution.

Method flow

The embodiment also provides a control method applicable to the lighting system.

When the control group information of the light unit 10 is not stored in the storage unit 40 or needs to be updated, the control method of the lighting system provided by the embodiment can generate or update the grouping scheme according to the user requirement, and specifically, as shown in fig. 7, the control method includes the following steps:

s1, storing the work log of the light unit 10 under the control of the single-lamp control unit 30 in the storage unit 40;

in the present embodiment, as shown in fig. 6, a work log stored in the storage unit 40 is graphically shown by specifically taking a periodic unit of the work log, that is, work data in a natural day, as a reference, where:

the names of the first to fourth lamps are longitudinally shown in the table;

the horizontal numerical designations in the table represent 24 hours of natural day equally divided by standard time, for example: 1 represents 0: 00-1: 00, 2 represents 1: 00-2: 00, …, 24 represents 23: 00-0: 00;

the white squares in the table represent that the light unit 10 is in the OFF state for the corresponding period; the black square and the gray square represent that the light unit 10 is in an ON state in the corresponding period, specifically, the black square represents that the light unit 10 emits light with a color of yellow, the square with oblique lines represents that the light unit 10 emits light with a color of white, further, each square is divided into two parts, and different light emitting states are respectively displayed by a full cell and a half cell, wherein the full cell is black/oblique lines representing that the light unit 10 is lit with 100% brightness, and the half cell is black/oblique lines representing that the light unit 10 is lit with 50% brightness.

The present embodiment shows a grouping logic of the optical unit 10: if the working time of at least two light units 10, such as the first light 101 and the second light 102, exceeds the preset time T1(T1< T) within the preset time T, the first light 101 and the second light 102 are considered to be frequently working together, and are divided into the same control group for group control; when the number of the qualified control groups is more than four, that is, the number of the scene keys of the grouping control unit 20 is more than the maximum number, the actual common working time T2 is compared, and the information of the four groups of control groups with the longest actual common working time is stored in the storage unit 40.

In the present embodiment, the behavior of the light units 10 that are not grouped is set by the user.

In some embodiments, the user may also formulate rules and filter groupings according to other data in the working log in combination with actual needs, for example, in another embodiment, the grouping logic of the light unit 10 differs from that shown above in this embodiment in that: the same light unit 10 can only be selected effectively once and only for the first time; the grouping order of the control groups is formed in sequence according to the natural time order of the periodic units; for example, when the first lamp 101 and the second lamp 102 are operated at the earliest time when the common operation time exceeds the preset time by 4 hours, for example, AM7:00, between 0:00 and 24:00, the first lamp 101 and the second lamp 102 are considered to be frequently operated together, and the processing unit 50 divides the operation into a first control group; next, at AM11:00, when the working time of the second lamp 102, the third lamp 103, and the fourth lamp 104 exceeds 4 hours, it is determined that the second lamp 102, the third lamp 103, and the fourth lamp 104 are often working together, but since the second lamp 102 has been selected and divided into the first control group, it cannot be selected again, the processing unit 50 divides the third lamp 103 and the fourth lamp 104 into the second control group, under the grouping logic, it can be ensured that the light units 10 in each control group are not duplicated, in other embodiments, the user can also set up other grouping logics to achieve more diversified needs.

Specifically, referring to fig. 6, in the present embodiment, the preset time T is a natural day, i.e., 24 hours, the preset time T1 is 4 hours, and the preset time T2 is 6 hours.

It should be noted that the cooperative work defined in this embodiment may be continuous cooperative work or cumulative cooperative work, and T, T1 and T2 are only shown as specific examples in this embodiment, and those skilled in the art can define specific durations of T and T1 by themselves according to needs, theoretically, the longer the T is set, the closer the user habit is to reality, the shorter the T is set, the higher the efficiency of generating the job log for reference is, and users can balance themselves according to actual needs without further details.

S2, based on the results of analyzing the work log, a control group of light units 10 is generated or adjusted.

According to the work log shown in fig. 6, the processing unit 50 divides the light units 10 into three control groups, respectively:

the first control group: a first signal lamp 101, a second signal lamp 102;

and control group two: a first lamp 101, a fourth lamp 104;

and a control group III: a second lamp 102 and a third lamp 103.

In this embodiment, a scene may also be created for the generated or adjusted control group, and the creation mode of the scene is as follows: the scene is generated based on the control group information and the behavior data of the light units 10 within the same control group within the common working time period.

Specifically, taking the working log shown in fig. 6 as an example, a scenario is created:

scene one:

3: 00-5: 00, a first lamp 101 with yellow luminous color and 50% brightness; a second lamp 102, which has white light emitting color and 50% brightness;

9: 00-13: 00, a first lamp 101 with yellow luminous color and 100% brightness; the second lamp 102 has yellow light color and 100% brightness.

Scene two:

13: 00-16: 00, a first lamp 101, the luminous color is yellow, and the brightness is 100%; a fourth lamp 104 with white light and 100% brightness;

16: 00-17: 00, a first lamp 101, the luminous color is yellow, and the brightness is 100%; a fourth lamp 104 with yellow color and 50% brightness;

scene three:

19: 00-23: 00, 102, yellow luminous color and 50% brightness; the third lamp 103 is white in light emitting color and 100% in brightness.

The control group information and the scene information are generated and then stored in the storage unit 40.

It should be noted that, in the present embodiment, the creation of the scene corresponds to the control group, for example, the scene one is created based on the control group one, and the behavior data of the light units 10 in the scene one selected in the control group one in the common working time period specifically includes: time period information in which each light unit 10 is in the ON state; emission color information of each light unit 10; luminance information of each light unit 10.

In some embodiments, the user may also select other information or create scenes in other manners, for example, the user may create multiple scenes for the same control group, for example, four scenes, namely scene one to scene four, where the scene one is generated based on the work log of the user in the periodic unit, and the scene two to scene four are directly set by the user according to the use requirement, specifically, taking the work log shown in fig. 6 as an example, that is:

the first control group:

scene one: 3: 00-5: 00, a first lamp 101 with yellow luminous color and 50% brightness; a second lamp 102, which has white light emitting color and 50% brightness;

Scene two to scene four: and (4) user-defined setting.

And control group two:

scene one: 13: 00-16: 00, a first lamp 101, the luminous color is yellow, and the brightness is 100%; a fourth lamp 104 with white light and 100% brightness;

scene two to scene four: and (4) user-defined setting.

And a control group III:

scene one:

Scene two to scene four: and (4) user-defined setting.

Further, in some embodiments, a large scene is created according to the behavior of the light units 10 in at least one control group, and specifically, the large scene includes large scenes one to four, where the large scene one is a set of behaviors of all the light units 10 in each control group (i.e., scene one of the control groups one to three) in the periodic unit, and the large scenes two to four are a set of behaviors of the light units 10 in at least one of the scenes one to four of at least one of the control groups one to three.

In this embodiment, the method for controlling an illumination system further includes:

s3, the grouping control unit 20 retrieves the control group information and performs grouping control on the light units 10.

In this embodiment, the grouping control unit 20 stores the control group information and the scene information corresponding to the control group information, and allocates the control group information and the scene information to the scene control 21, specifically, allocates the scene one to the scene one key 211 control, allocates the scene to the scene two key 212 control, and allocates the scene three to the scene three key 213 control.

In this embodiment, the behavior of the light units 10 in the scene is controlled according to the time interval, and if the time for triggering the scene key is within the first time interval, the operating state of each light unit 10 in the first time interval is called to create the scene.

For example, when the user is pressing scene one key 211:

if the current time is within a time period of 3: 00-5: 00, the first signal lamp 101 is turned into/kept in an ON state, the light emitting color is yellow, and the brightness is 50%; the second lamp 102 is turned ON and remains ON, and emits white light with a brightness of 50%.

If the current time is within the time interval of 9: 00-13: 00, the first signal lamp 101 is turned into/kept in an ON state, the light emitting color is yellow, and the brightness is 100%; the second lamp 102 is turned ON and remains ON, and emits yellow light with a brightness of 100%.

If the current time is out of the above two periods, the behavior is defined by the user, and some defining manners are given as illustrations in the present embodiment, but not as limitations of the present embodiment, for example: the first and

second lamps

101 and 102 are set to behave the same as one of the above two periods or the first and

second lamps

101 and 102 are set to be unresponsive.

It should be noted that the work log content, the control group grouping logic, the scene generation logic, and the behavior logic of the light unit 10 in the scene given in the present embodiment are all exemplary and not limiting, and some equivalent or equivalent substitutions may be made by the user according to the technical teaching given in the present embodiment.

When the control group information of the light unit 10 is stored in the storage unit 40, step S2 of the control method of the lighting system according to the present embodiment further includes: the original control group information and the scene information are replaced with new control group information and scene information obtained according to the latest work log analysis, so as to adjust the control group of the light unit 10.

In the preferred technical solution of the present embodiment, the single-lamp control unit 30 and the packet control unit 20 are integrated in the same multifunctional control unit 3020, and the multifunctional control unit 3020 can implement single-lamp control on the light unit 10 and can also implement packet control on the bluetooth communication module 20BLE in the bluetooth network, so that the manufacturing cost is saved and convenience is provided for the user.

And the grouping model is perfected in a machine learning mode, and a grouping scheme more close to the habit of the user can be obtained based on continuously updated original data.

So far, the technical solutions of the present invention have been described with reference to the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific technical solutions.
