Description
Technical Field
The invention relates to the technical field of lamp bead effects, in particular to a luminous group effect control method.
Background
The light bar is widely applied due to the fact that people love and pursue light colors, the light bar is used for decorating the outlines of buildings and bridges in cities from small to small, advertising boards to large, and the outlines of buildings and bridges in cities from large to large, and the light bar shows brilliant and colorful effects at night.
The lamps distributed in scattered or disordered way can only form the effects of running water lamps of marquee and the like the lamp strips formed by the lamps arranged in linear way, the existing lamp group formed by the lamps distributed in the scattered or disordered way has no definite development direction and effective development method in the aspect of effect control, so that effect control personnel are in a strong and ubiquitous situation, and the effect of the lamp group developed by adopting the traditional method in the face of the scattered distribution of the lamps is simple and repeated, such as monotonous circulation and alternate illumination of colored lamps of a Christmas tree, and such as the lamp group is statically and constantly bright in one color, and the application scene is very limited.
Disclosure of Invention
The present invention is directed to a method for controlling the effect of a light-emitting group, so as to solve the problems mentioned in the background art.
The invention inspires from the lighting law of the firefly group, if the grassland has a plurality of fireflies which are distributed scattered, the night shade is initially fallen, the fireflies start to light up in a certain place, and the fireflies are extinguished after being lighted, and careful observation can find that the lighting picture of the firefly group looks like 'shape scattering' and 'shape scattering', and the lighting picture of the fireflies is stable in a time period although the overall lighting picture is continuously changed, the ratio of the number of the lighted fireflies to the number of the overall fireflies is almost stable in the time period, and the lighting ratio is stable in the process, and further thought, in the lighted fireflies, the same effect as that of some breathing lamps, some flickering and the ratio of the number of various lighting effects to the overall lighting number of the fireflies in the time period, and the effect ratio is stable in the process; if we make the individual basic effects required for the glowworm group lighting like: the lamp group reasonably expresses the basic effects by controlling the luminous probability of the lamp group and controlling the effect ratio of various basic effects, so that the lamp group effect which is as vivid and interesting as a firefly and continuously changed can be efficiently simulated, and further the starry sky luminous law is found to be similar to the luminous law of the firefly group, so that if the technical scheme is realized, the starry sky effect which is continuously changed can be efficiently simulated.
In order to achieve the purpose, the invention provides the following technical scheme:

The addition of the initial execution link is to consider the problem that the initial execution time synchronization of all the lamp modules brings about the synchronization of the expression effect of partial lamps due to the initial execution time synchronization when the parameters are just started to execute, set the random delay parameters in the link, make the initial execution times of the lamp modules different, solve the problem that the partial lamps only express the synchronization effect during the initial execution of the parameters, and enrich the developable content of the lamp group.
In the 'effect selection link', the lamp module only generates random numbers, and the basic effect is selected according to the minimum interval of the index variable of the interval array which is obtained by calculating the index variable of the ratio array and corresponds to the random numbers.
And (3) whether to express the link or not, wherein the lamp only generates a random number again by the module, the random number is compared with the light-emitting ratio parameter, whether to control the lamp to express the basic effect selected by the previous link or not is confirmed, if so, the lamp is controlled to express the effect, and if not, the lamp is controlled to be turned off only for waiting for the duration equal to the duration of the selected basic effect.
After the lamp module only executes the first round of the above links, the 'initial execution link' does not need to be executed any more, and then the 'effect selection link' and the 'whether expression link' are executed in a circulating way; under the working flow of the lamp modules reasonably designed in this way, each lamp module is in a state of continuously selecting a basic effect, expressing the selected basic effect or being turned off for a time length equal to the duration of the selected basic effect, so that the effect of the lamp group has an adjustable function, a light-emitting expected value of the lamp group can be calculated according to related parameters through a specific formula, the light-emitting expected value is a mathematical expected value of the number of lamps expressing any all basic effects in the lamp group after the parameters are executed, the effect expected value of various basic effects is calculated, and the effect expected value is a mathematical expected value of the number of lamps expressing a certain basic effect in the lamp group after the parameters are executed; the expected value of the lighting is for a lamp group and the expected value of the effect is for a basic effect, the expected value of the lighting and the expected value of the effect having the relationship: the sum of the expected effect values of all the basic effects is the expected lighting value of the lamp group.
The method can edit a plurality of required basic effects, reasonably set subscript variable values and random time delay of ratio arrays as required, uniformly transmit data parameters to each lamp module by a main control, uniformly enable each lamp module to execute parameters, adjust the luminous expected value of a lamp group by uniformly adjusting the percentage of luminous ratio parameters P in each lamp module, and adjust the effect expected value of the corresponding basic effect by uniformly adjusting the subscript variable values of the ratio arrays in each lamp module, thereby realizing development and control of the lamp group effect; by the method, the constantly changing lamp group effects which are similar to starry sky, firefly groups and other traditional development methods are edited, the workload is large, and the aesthetic direction is difficult to grasp can be developed and simulated simply, quickly and efficiently.
As a further scheme of the invention, each lamp is only assigned with the identification number, so that the range of the parameter function number can be customized, and one lamp group can be freely divided into a plurality of lamp groups to carry out different lamp group effect control.

A method for controlling the effect of luminous group includes such steps as providing a group of lamps, receiving and storing data, and executing parameters independently, transmitting data parameters to the lamp modules by master controller, including random delay T, luminous ratio P, effect array F [ i ] and occupied ratio array A [ i ], creating basic effect array by edited and needed basic effect, and setting the index variable of the occupied ratio array to the index variable of the effect array.
Referring to fig. 1, fig. 1 is a schematic view of a lamp module-only workflow, which includes the following steps:
and an initial execution link, wherein a random delay function is set in the link, so that the lamp module can randomly delay and execute parameters within random delay time, the initial execution parameter time of the lamp module is different, and the synchronization phenomenon is avoided.
And (3) selecting an effect link: the module generates a 0-1 random number R0, and compares the random number R0 with an interval array subscript variable, wherein the interval array can be represented by the calculation of the occupation ratio array subscript variable as follows:
wherein
Selecting the basic effect according to the minimum interval of the index variable of the interval array corresponding to the random number R0 when
Selecting a basic effect F [ n ]]Wherein A [0 ]]I is 0, i is the total number of basic effects, and n is a natural number which is more than 0 and not more than i;
whether to express links: the module generates a 0-1 random number R1, compares the random number with the light-emitting ratio parameter P, confirms whether to express the basic effect selected in the previous link, if the basic effect is expressed (R1 & lt & gtP), the lamp module only allows the lamp to express the selected basic effect; if not (R1 > P), the lamp is simply extinguished waiting for a duration equal to the duration of the basic effect.
When the lamp only starts to execute parameters, and the first round of the links is finished, the 'effect selection link' and the 'whether expression link' are executed in a circulating and alternating mode.
Under the work flow mode that the lamp only has the module, the following four important work parameter calculation modes exist:

fourthly, calculating the expected effect value corresponding to the basic effect F [ n ]:
E(F[n])＝E(l)*Rn
where E (Fn) is the expected value of the effect Fn, i.e. the mathematical expected value of the number of lamps expressing the basic effect Fn in the lamp group, E (l) is the expected value of the light emission of the lamp group, and Rn is the ratio of the basic effect Fn to the effect.
"expected lighting value" means the mathematical expected value of the number of lamps in a lamp group expressing any all basic effects, and "expected effect value" means the mathematical expected value of the number of lamps in a lamp group expressing a certain basic effect; the lighting expectation value is for a lamp group, and the effect expectation value is for a basic effect, and the relationship between the "lighting expectation value" and the "effect expectation value" is: adding the effect expected values of all basic effects to obtain the light emitting expected value of the lamp group;

The expected effect value and the effect ratio are in a proportional relationship, the expected effect value and the effect ratio have respective meanings, the expected effect value can specifically represent an average value of the number of lamps expressing a certain basic effect in the lamp group, and the effect ratio can specifically represent a ratio of the expected effect value of the certain basic effect to a sum of the expected effect values of all the basic effects (namely, an expected lighting value).
The method can edit a plurality of required basic effects, reasonably set the subscript variable values and random time delay of the ratio array as required, uniformly transmit parameters to each lamp module by the main control, uniformly enable each lamp module to execute the parameters, adjust the luminous expected value of a lamp group by uniformly adjusting the percentage of the luminous ratio parameter P in each lamp module, and adjust the effect expected value of the basic effect by uniformly adjusting the subscript variable values corresponding to the basic effects in each lamp module, thereby developing and controlling the lamp group effect.
Through the lamp group effect control method, the lamp group effect which is similar to that of starry sky and is edited by traditional development methods such as fireflies and the like can be developed and simulated simply, quickly and efficiently, so that the lamp group effect control process is optimized to be the basic editing effect and the basic distribution effect, the workload of the lamp group effect control process is reduced, and meanwhile, the content of the lamp group effect is greatly enriched.
As a further scheme of the invention, each lamp is only assigned with an identification number, so that the range of the parameter function number can be customized, and one lamp group can be freely divided into a plurality of lamp groups to carry out different lamp group effect control. Because each lamp only has a number, the equal-difference delay parameters can be set in the initial execution link, the lamp group effect is increased, and the development content can be realized.
