Description

Technical Field

[0001] The present invention relates to the field of lighting dimming computer control, and in particular to a dimming compatible control method and a lighting system, a control device, and a storage medium. Background Art

[0002] In the exhibition hall, various lighting fixtures can be arranged on the ceiling or side walls, and the staff can place the exhibits in different areas of the exhibition hall. Generally speaking, different exhibits have different characteristics such as colors, and the required lighting requirements vary according to the effects that the staff want to show to the audience. In addition, when the staff place the exhibits, there will generally be at least one light-emitting module near a certain exhibit that projects on the exhibit. However, the staff needs to consider that the light emitted by the light-emitting modules around the exhibit that project on other exhibits will also have a certain impact on the illumination of the exhibit area.

[0003] Therefore, every time the staff adds a new exhibit or changes the position of an exhibit in the exhibition hall, the staff needs to re-plan the lighting system of the entire exhibition hall and reset the luminous illumination value of each light-emitting module. The light-emitting module then emits light according to the set luminous illumination value. However, this process requires a lot of time and manpower, which does not meet the fast-paced exhibition requirements of today's exhibition halls. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a dimming compatible control method and a lighting system, a control device, and a storage medium, which are fast and convenient to process, have low operating costs, effectively meet the illumination requirements of exhibits, and are simple and reliable to use.

[0005] A dimming compatible control method according to an embodiment of the first aspect of the present invention is applied to a lighting system, wherein the lighting system includes a plurality of light-emitting modules and a plurality of marking terminals that are communicatively connected to each other, wherein the marking terminals are used to set a light demand value, and wherein the light-emitting modules are provided with a communication range, wherein the light-emitting modules can be wirelessly connected to each marking terminal within the communication range, and wherein the light-emitting modules can obtain distance information and light demand values ​​of each marking terminal within the communication range; the dimming compatible control method includes:

[0006] Counting the number of identifications of all light-emitting modules, where the number of identifications is the number of marking terminals within the communication range corresponding to the light-emitting module;

[0007] Determine the priority of each light-emitting module according to the number of identifications, and sort the light-emitting modules from high to low according to the priority, wherein the light-emitting module with a large number of identifications has a higher priority;

[0008] Each light-emitting module sequentially performs a dimming correction step, wherein the dimming correction step includes: screening out the mark terminal closest to the light-emitting module within the communication range; obtaining a weighted value of each mark terminal according to the distance information of each mark terminal within the communication range, wherein the weighted value of the mark terminal closer to the light-emitting module is larger, and the weighted value of the mark terminal farther from the light-emitting module is smaller, and a total light weighted value is obtained by weighted calculation using the light requirement value and the weighted value of each mark terminal; obtaining a luminous illumination value of the light-emitting module based on a light attenuation model using the total light weighted value and the distance information of the mark terminal closest to the light-emitting module; the light-emitting module emits light according to the luminous illumination value, and obtains a light influence value of each mark terminal based on a light attenuation model using the luminous illumination value of the light-emitting module and the distance information of each mark terminal within the communication range, and corrects the light requirement value of each mark terminal using the light influence value, and the dimming correction step of the light-emitting module ends;

[0009] The next light-emitting module performs the dimming correction step, and marks the illumination requirement value of the terminal as the illumination requirement value corrected in the last dimming correction step.

[0010] A dimming compatible control method according to an embodiment of the present invention has at least the following beneficial effects:

[0011] In the dimming compatible control method of the present invention, the marking terminal can be set on the exhibits one by one, and the lighting requirement value required by the corresponding exhibits is recorded. The staff can add the exhibits together with the marking terminal to the exhibition hall, remove them from the exhibition hall, or move them. At this time, each light-emitting module that is connected to each other automatically executes the dimming compatible control method to adjust its own luminous illumination value. Each light-emitting module can set a communication range, which can be regarded as the area range that the light emitted by the light-emitting module can affect. The illumination of the position corresponding to the marking terminal within the communication range will be affected by the light-emitting module. The more the number of marked terminals within the communication range, the more exhibits will be affected when dimming the light module. Therefore, the priority of each light module is determined according to the number of marks. The light module with a large number of marks has a higher priority. The light modules with higher priorities are first dimmed. In the dimming correction step, considering that the light module is usually relatively close to an exhibit for targeted projection, of course, the light emitted by the light module will also affect the lighting of other exhibits. Therefore, the marked terminal closest to the light module within the communication range is first screened out. At the same time, the weighted value of each marker terminal is obtained according to the distance information of each marker terminal within the communication range, among which the weighted value of the marker terminal closer to the light-emitting module is larger, while the weighted value of the marker terminal farther from the light-emitting module is smaller. Finally, the weighted calculation is performed to obtain the total light weighted value. At this time, the total light weighted value and the distance information of the marker terminal closest to the light-emitting module are used to obtain the luminous illumination value of the light-emitting module based on the light attenuation model. The luminous illumination value not only meets the illumination demand for the closest exhibit, but also can provide appropriate illumination for the surrounding exhibits. At this time, the surrounding exhibits provide Partial illumination is obtained, so the luminous illumination value of the light-emitting module needs to be corrected. After the correction, the next light-emitting module continues to perform the dimming correction step, and so on. It can be understood that when there are fewer mark terminals within the communication range of some light-emitting modules, then after the dimming correction of the light-emitting modules with a higher order is completed, the light-emitting modules with a lower order will also perform dimming correction to provide fill light for the exhibits corresponding to a small number of mark terminals to meet the basic lighting requirements of exhibits at various positions in the exhibition hall. This design is fast and quick to process, with low operating costs, effectively meets the illumination requirements of exhibits, and is simple and reliable to use.

[0012] According to some embodiments of the present invention, the step of sorting the light-emitting modules from high to low according to priority includes: when multiple light-emitting modules have the same number of identifiers, the multiple light-emitting modules with the same number of identifiers are randomly sorted in sequence.

[0013] According to some embodiments of the present invention, the step of deriving a weighted value of each marker terminal according to distance information of each marker terminal within a communication range includes:

[0016] According to some embodiments of the present invention, the step of calculating the total illumination weighted value using the illumination requirement value and the weighted value of each marker terminal includes:

[0017] N s =a 1 *N 1 +a 2 *N 2 +…+a n *N n ;

[0018] Among them, N s is the total value of light weight, a 1 、a 2 , …a n is the weight value of each marked terminal, N 1 、N 2 ,…N n is the lighting requirement value of the marked terminal.

[0019] According to some embodiments of the present invention, the step of deriving the luminous illumination value of the light-emitting module based on a light attenuation model by using the total light weighted value and the distance information of the marking terminal closest to the light-emitting module includes:

[0020]

[0021] Among them, X is the luminous illumination value, L 1 is the distance value of the marking terminal closest to the light-emitting module, and α is the light attenuation coefficient that varies with distance.

[0022] According to some embodiments of the present invention, the illumination impact value of each marker terminal is obtained based on the illumination attenuation model using the luminous illumination value of the light-emitting module and the distance information of each marker terminal within the communication range, and the illumination requirement value of each marker terminal is corrected using the illumination impact value, including:

[0023] Calculate the lighting impact value of each marker terminal:

[0024]

[0025] Among them, M nis the illumination impact value of each marker terminal, L n is the distance value of each marker terminal within the communication range, n is the number of marker terminals within the communication range, n = {1, 2, ... n};

[0026] Modify the lighting requirement value of each marker terminal according to the lighting impact value:

[0027] N cn =N n -M n ;

[0028] Among them, N cn is the corrected illumination requirement of each marker terminal, N n is the lighting requirement value of each marking terminal before correction.

[0029] According to some embodiments of the present invention, in the step of correcting the illumination requirement value of each marker terminal using the illumination impact value, if the illumination requirement value of the marker terminal after correction is less than 0, the illumination requirement value of the marker terminal after correction is set to 0.

[0030] According to an embodiment of the second aspect of the present invention, the lighting system includes: a plurality of mark terminals, which are used to set lighting requirement values; a plurality of light-emitting modules that are communicatively connected to each other, each light-emitting module being provided with a communication range, and capable of wirelessly communicating with each mark terminal within the communication range, and capable of obtaining distance information and lighting requirement values ​​of each mark terminal within the communication range; each of the light-emitting modules executes the dimming-compatible control method disclosed in any of the above embodiments according to changes in the mark terminal to obtain its own luminous illuminance value, and emits light according to the luminous illuminance value.

[0031] The lighting system according to the embodiment of the present invention has at least the following beneficial effects:

[0032] In the lighting system of the present invention, the marking terminal can correspond to each exhibit one by one, and record the lighting demand value required by the exhibit. The staff can add the exhibits together with the marking terminal into the exhibition hall, remove them from the exhibition hall or move them. Each of the light-emitting modules executes the dimming compatible control method disclosed in any of the above embodiments according to the changes in the marking terminal to obtain its own luminous illumination value, and emits light according to the luminous illumination value. The design is fast and quick to process, has low operating costs, effectively meets the illumination requirements of exhibit display, and is simple and reliable to use.

[0048] like Figure 1 , Figure 2 As shown, a dimming-compatible control method according to an embodiment of the first aspect of the present invention is applied to a lighting system, wherein the lighting system includes a plurality of light-emitting modules communicatively connected to each other and a plurality of marking terminals, wherein the marking terminals are used to set lighting requirement values, and the light-emitting modules are provided with a communication range, wherein the light-emitting modules can be wirelessly connected to each marking terminal within the communication range, and wherein the light-emitting modules can obtain distance information and lighting requirement values ​​of each marking terminal within the communication range.

[0049] Among them, the lighting system can be applied in an exhibition hall, the light-emitting module generally includes a first control module, a switch driving module, a first wireless communication module and a light source module, the first control module may include an MCU or a CPU and its affiliated circuits, the switch driving module may include a number of semiconductor switch tubes, the light source module may include a plurality of LED light strings, the switch tubes are connected in series with the LED light strings, the first control module is connected to the switch driving module to output a PWM duty cycle signal according to the luminous illumination value to adjust the working current of the LED light string, thereby adjusting the luminous illumination of the light-emitting module, the first wireless communication module may be a Bluetooth module or a WiFi module, in addition, the first control modules of each light-emitting module may be wirelessly connected to each other through the first wireless communication module, or a signal transmission bus may be arranged in the exhibition hall, each first control module is connected to the signal transmission bus, and each first control module is connected to each other through the signal transmission bus.

[0050] The marking terminal may include a box body and a second control module and a second wireless communication module arranged in the box body. The second control module may also include an MCU or a CPU and its affiliated circuits. The second wireless communication module may use a Bluetooth module or a WiFi module that can establish a wireless communication connection with the first wireless communication module. The staff can set the lighting requirement value in the second control module, wherein the lighting requirement value can be set by the staff according to the different characteristics of the exhibits such as the color of the exhibits themselves or the differences in the effects that the staff wants to show to the audience. It should be noted that although there are differences in the lighting requirement values ​​of different exhibits, generally speaking, the difference is not large.

[0051] Specifically, the communication range of the light-emitting module can be formulated by setting the signal receiving and sending range of the first wireless communication module. As for the light-emitting module obtaining the distance information of the marking terminal, a wireless signal strength detection module can be provided in the light-emitting module. The wireless signal strength detection module can be a signal strength sensor or a signal strength amplitude detection circuit. The distance information is judged according to the signal strength during the wireless communication connection established between the first wireless communication module and the second wireless communication module. Alternatively, an ultrasonic ranging receiver is provided on the light-emitting module, and an ultrasonic ranging transmitter is provided on the marking terminal. The ultrasonic ranging receiver can receive the ultrasonic signal emitted by the ultrasonic ranging transmitter, and judge the distance information according to the transmission time difference of the ultrasonic signal.

[0052] like Figure 3 , Figure 4 As shown, the dimming compatible control method includes:

[0053] S410, counting the number of identifications of all light-emitting modules, where the number of identifications is the number of marked terminals located within the communication range corresponding to the light-emitting module;

[0054] S420, determining the priority of each light-emitting module according to the number of identifications, and sorting the light-emitting modules from high to low according to the priority, wherein the light-emitting module with a large number of identifications has a higher priority;

[0055] S430, each light-emitting module sequentially performs a dimming correction step, wherein the dimming correction step includes: S510, screening out the mark terminal closest to the light-emitting module within the communication range; S520, obtaining a weighted value of each mark terminal according to the distance information of each mark terminal within the communication range, wherein the weighted value of the mark terminal closer to the light-emitting module is larger, and the weighted value of the mark terminal farther from the light-emitting module is smaller, and the total weighted value of the light is obtained by weighted calculation using the light requirement value and the weighted value of each mark terminal; S530, using the total weighted value of the light and the distance information of the mark terminal closest to the light-emitting module to obtain the luminous illumination value of the light-emitting module based on the light attenuation model; S540, the light-emitting module emits light according to the luminous illumination value, and using the luminous illumination value of the light-emitting module and the distance information of each mark terminal within the communication range to obtain the light impact value of each mark terminal based on the light attenuation model, and using the light impact value to correct the light requirement value of each mark terminal, the dimming correction step of the light-emitting module ends;

[0056] S440: The next light-emitting module performs a dimming correction step, and marks the illumination requirement value of the terminal as the illumination requirement value corrected in the last dimming correction step.

[0057] In the dimming compatible control method of the present invention, the marking terminal can be set on the exhibits one by one, and the lighting demand value required by the corresponding exhibits is recorded. The staff can add the exhibits together with the marking terminal into the exhibition hall, remove them from the exhibition hall or move them. At this time, each light-emitting module that is connected to each other automatically executes the dimming compatible control method to adjust its own luminous illumination value. Each light-emitting module can set a communication range, which can be regarded as the area that can be affected by the light emitted by the light-emitting module. The illumination of the position corresponding to the marking terminal within the communication range will be affected by the light emitted by the light-emitting module, and the more marking terminals there are within the communication range, the more it proves that When dimming the light-emitting module, the more exhibits it affects, the priority of each light-emitting module is determined according to the number of identifications. The light-emitting module with a large number of identifications has a higher priority. The light-emitting module with a higher priority is dimmed first. In the dimming correction step, considering that the light-emitting module is usually relatively close to an exhibit for targeted projection, of course, the light emitted by the light-emitting module will also affect the lighting of other exhibits. Therefore, the mark terminal closest to the light-emitting module within the communication range is first screened out. At the same time, the weighted value of each mark terminal is obtained according to the distance information of each mark terminal within the communication range, wherein the mark terminal closer to the light-emitting module has a higher priority. The weighted value of is larger, while the weighted value of the tag terminal farther from the light-emitting module is smaller. Finally, the weighted calculation is performed to obtain the total light weighted value. At this time, the total light weighted value and the distance information of the tag terminal closest to the light-emitting module are used to obtain the luminous illumination value of the light-emitting module based on the light attenuation model. The luminous illumination value not only meets the illumination demand for the closest exhibit, but also can provide appropriate illumination for the surrounding exhibits. Since the surrounding exhibits have obtained partial illumination at this time, it is necessary to correct the luminous illumination value of the light-emitting module. After the correction, the next light-emitting module continues to perform the dimming correction step. By analogy, it can be understood that when some light-emitting modules are within the communication range, If there are fewer marking terminals, then after the dimming correction of the light-emitting modules in the earlier order is completed, the light-emitting modules in the later order will also be dimmed to provide fill light for the exhibits corresponding to a small number of marking terminals, so as to meet the basic lighting requirements of the exhibits at various positions in the exhibition hall. It should be noted that after the dimming correction of each light-emitting module in the exhibition hall, the lighting at the location of each exhibit roughly meets the lighting requirement value, but it is not completely equal, and there may be certain deviations. This design mainly achieves automatic dimming and roughly compatibility with the lighting requirements of the exhibits in the exhibition hall at a lower computing cost. This design is fast and quick to process, has low operating costs, effectively meets the illumination requirements of exhibits, and is simple and reliable to use.

[0058] Since in each dimming correction step, the illumination requirement value of the marked terminal within the communication range of the light-emitting module performing the dimming correction step needs to be corrected, and the same marked terminal may fall into two light-emitting modules with the same number of identifiers, if the two light-emitting modules perform the dimming correction step at the same time, the correction processing will be disordered. Therefore, in some embodiments of the present invention, the ordering of the light-emitting modules from high to low according to the priority includes:

[0059] When the number of identifications of a plurality of light-emitting modules is the same, the plurality of light-emitting modules with the same number of identifications are randomly sorted in sequence, so that each light-emitting module can perform the dimming correction step in an orderly manner.

[0060] In some embodiments of the present invention, the step of deriving a weighted value of each marker terminal according to the distance information of each marker terminal within the communication range includes:

[0061]

[0062] Among them, a n is the weight value of the marked terminal, L n is the distance value between the marking terminal and the light-emitting module, n is the number of marking terminals within the communication range, n={1, 2, ...n}, and R is the sum of the reciprocals of the distance values ​​of each marking terminal within the communication range.

[0063] Since the light-emitting module needs to give priority to the lighting conditions of the nearest exhibits, it is necessary to set a larger weighted value for the marker terminal closer to the light-emitting module, and a smaller weighted value for the marker terminal farther from the light-emitting module. Therefore, the weighted value is calculated using the inverse of the distance value of each marker terminal. For example, there are a first marker terminal and a second marker terminal within the communication range, and the distance between the first marker terminal and the light source module is L. 1 , the distance between the second marking terminal and the light source module is L 2 ,but That is, it can be concluded that

[0064] In some embodiments of the present invention, the step of calculating the total illumination weighted value using the illumination demand value and the weighted value of each marker terminal includes:

[0065] N s =a 1 *N 1 +a 2 *N 2 +…+a n *N n ;

[0066] Among them, N s is the total value of light weight, a 1 、a2 , …a n is the weight value of each marked terminal, N 1 、N 2 ,…N n is the lighting requirement value of the marked terminal.

[0067] The total lighting weighted value is calculated using the lighting demand value and weighted value of each marker terminal. This can make the total lighting weighted value compatible with the lighting demands of each marker terminal within the communication range. At the same time, the lighting demand value of the marker terminal closest to the light source module can be used as the main factor. As the distance increases, the influence of the lighting demand values ​​of other marker terminals decreases, allowing the exhibition hall dimming requirements to be planned more reasonably.

[0068] In some embodiments of the present invention, the method of using the total value of the light weight and the distance information of the marking terminal closest to the light module to obtain the luminous illumination value of the light module based on the light attenuation model includes:

[0069]

[0070] Among them, X is the luminous illumination value, L 1 is the distance value of the marking terminal closest to the light-emitting module, and α is the light attenuation coefficient that varies with distance.

[0071] It can be understood that the light emitting module emits light, and the light decays as the distance increases, and α is the light decay coefficient that changes with distance. The relationship between the luminous illumination value of the light emitting module and the light requirement value of the location of the marking terminal can be calculated based on the distance value between the marking terminal and the light emitting module. That is, the luminous illumination value of the light emitting module can be calculated based on the light requirement value (or the weighted total value) of the location of the nearest marking terminal, and the light intensity at the location of each marking terminal can also be calculated based on the actual luminous illumination of the light emitting module.

[0072] In some embodiments of the present invention, the illumination impact value of each marker terminal is obtained based on the illumination attenuation model using the illumination illumination value of the light-emitting module and the distance information of each marker terminal within the communication range, and the illumination requirement value of each marker terminal is corrected using the illumination impact value, including:

[0073] Calculate the lighting impact value of each marker terminal:

[0074]

[0075] Among them, M n is the illumination impact value of each marker terminal, L n is the distance value of each marker terminal within the communication range, n is the number of marker terminals within the communication range, n = {1, 2, ... n};

[0076] Modify the lighting requirement value of each marker terminal according to the lighting impact value:

[0077] N cn =N n -M n ;

[0078] Among them, N cn is the corrected illumination requirement value of each marker terminal, N n is the lighting requirement value of each marking terminal before correction.

[0079] Since the luminous illumination value of the light-emitting module is calculated according to the weighted total value of the illumination, and the light-emitting module emits light according to the luminous illumination value, the illumination impact value of each mark terminal location within the communication range can be calculated. It can be understood that the location of each mark terminal is affected by the light emitted by the light-emitting module, and the illumination requirement values ​​​​of other light-emitting modules are naturally reduced accordingly. Here, the original illumination requirement value is corrected by the illumination impact value.

[0080] Taking the tag terminal which is the second closest to the light-emitting module within the communication range as an example, it is affected by the light emission of the light-emitting module. Then the corrected light demand value is N c2 =N 2 -M 2 .

[0081] In some embodiments of the present invention, in the method of using the illumination influence value to correct the illumination requirement value of each marking terminal, if the illumination requirement value of the marked terminal after correction is less than 0, the illumination requirement value of the marked terminal after correction is set to 0, that is, during the correction process, after the illumination requirement value of some marking terminals is corrected once or multiple times, the illumination requirement value before correction is less than the illumination influence value affected by the illumination of the light-emitting module, then the illumination requirement value of the marked terminal after correction is less than 0. At this time, the illumination requirement value of the marked terminal after correction can be uniformly set to 0, and the subsequent dimming correction step of other light-emitting modules may cause the illumination at the position of the marked terminal to further increase. However, it is understandable that usually only one set of light-emitting modules corresponds to the vicinity of an exhibit, and other light-emitting modules have little effect on the illumination at the position of the exhibit. Even if it causes the illumination at the position of the marked terminal to further increase, it is still within an acceptable range.

[0082] According to the lighting system of the second aspect of the present invention, Figure 1 , 2As shown, it includes: a plurality of marking terminals, which are used to set the lighting requirement value; a plurality of light-emitting modules that are communicatively connected to each other, the light-emitting modules are provided with a communication range, the light-emitting modules can be wirelessly connected with each marking terminal located within the communication range, and the light-emitting modules can obtain the distance information and the lighting requirement value of each marking terminal within the communication range; each of the light-emitting modules executes the dimming compatible control method disclosed in any of the above embodiments according to the change of the marking terminal to obtain its own luminous illumination value, and emits light according to the luminous illumination value.

[0083] The lighting system here can adopt the lighting system structure of a dimming compatible control method of the first aspect embodiment of the present invention mentioned above, which will not be repeated here.

[0084] In the lighting system of the present invention, the marking terminal can correspond to each exhibit one by one, and record the lighting demand value required by the exhibit. The staff can add the exhibits together with the marking terminal into the exhibition hall, remove them from the exhibition hall or move them.
