Description
Technical Field
The application relates to the technical field of light control, in particular to a light effect control method, a light effect control device, lighting equipment and a computer readable storage medium.
Background
The professional lighting lamp in the market at present is mainly controlled by a DMX512 console, and the DMX512 console is based on a DMX512 control protocol to realize a communication mode. The data issued by the DMX512 console can be divided into two categories, one category is regular light pattern data, the other category is continuous light effect data, the regular light pattern data is to change the light effect parameters of a certain lamp, such as color, color temperature, brightness, etc., and the continuous light effect data refers to that the console has formed a dynamic light effect change effect by setting the light effect parameters of each lamp.
However, in the scene of a professional lighting lamp, a gradual change control process is usually required for the light efficiency parameter of the lamp, for example, if the brightness of the lamp needs to be adjusted from 20% to 50%, the brightness of the lamp cannot be directly changed, but the brightness needs to be slowly increased from 20% to 50% in a certain gradual change time, otherwise, the poor experience of flickering of the light efficiency is brought to the user. However, because the data issued by the DMX512 console is different, the lamp generally cannot be effectively compatible with the two data modes, for example, under continuous light effect data, the lamp directly controls the light effect parameter according to the received data because the issued data is the continuously-changed light effect parameter obtained through differential processing, and under conventional light mode data, the lamp needs to be subjected to differential processing by itself because the received data is not the continuously-changed light effect parameter, so that gradual control of light effect is realized, and abnormal light effect flicker is avoided.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the description of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
In the description of the present application, the word "for example" is used to mean "serving as an example, instance, or illustration. Any embodiment described as "for example" in this disclosure is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the application. In the following description, details are set forth for purposes of explanation. It will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. In other instances, well-known structures and processes have not been described in detail so as not to obscure the description of the application with unnecessary detail. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
In order to facilitate understanding of the complete implementation scheme of the light efficiency control method provided by the embodiment of the application, related implementation scenes of the light efficiency control method are first described in detail as follows.
In the field of light control, such as more common stage lights, photography lights, landscape lights, etc., the lighting efficiency of a lighting device is typically achieved due to the DMX512 console being based on the DMX512 control protocol. In the DMX512 control protocol, a packet of data can carry 512 bytes at maximum, and as long as communication is normal, the console will send data immediately, and the time interval for sending data is about 12ms, which means that the console can send a large amount of data to the lighting device in a short time. Specifically, as shown in fig. 1, a schematic diagram of a data format under a DMX512 protocol according to an embodiment of the present application is shown.
Further, the data types issued by the DMX512 console generally include two types, one type is regular light mode data, and the other type is continuous light effect data, in order to facilitate understanding of the difference between the data types issued by the DMX512 console, for example, the brightness of the lamp is adjusted from 20% to 50%, if the data types issued by the DMX512 console are regular light mode data, the brightness control parameters are 50% in a plurality of continuous frames of DMX512 protocol data received by the lighting device, and if the data types issued by the DMX512 console are continuous light effect data, the brightness control parameters are 20%, 22% and 24% in sequence in a plurality of continuous frames of DMX512 protocol data received by the lighting device, until the final 50%.
On the basis of the above, considering that in the professional lighting lamp scene, the lighting effect parameter of the lamp needs to have a gradual change control process, therefore, for the received conventional light mode data, a differentiating process needs to be executed by the lighting equipment, and the brightness is adjusted from 20% to 50% according to a certain buffering time, otherwise, for the received continuous light effect data, as the continuous light effect parameter is issued by the DMX512 console, the lighting equipment directly adjusts according to the light effect parameter at the moment without additional gradual change processing, otherwise, higher delay is generated. It can be seen that, for different types of data issued by the DMX512 console, different processing needs to be performed by the lighting device, that is, the lighting device does not need additional ramp processing in the continuous light effect data mode, whereas the conventional light mode data needs the lighting device to perform ramp processing, so that in a normal case, the lighting device cannot effectively be compatible with different types of data issued by the DMX512 console, and the light effect control of the lighting device is affected.
In order to solve the above-mentioned problem, the prior art proposes a method of using one byte of data in the DMX512 control protocol to represent the data type issued by the console, for example, using the 512 th byte in the DMX512 protocol data for type judgment, 1 represents the conventional light mode data, 2 represents the continuous light effect data, and the lighting device determines whether to execute the buffer processing after determining the received data type, but this occupies one byte of the DMX512 protocol, resulting in less data carried by the protocol and wasting some resources. Therefore, the embodiment of the application provides a light effect control method applied to target lighting equipment, which does not occupy additional data packets of a DMX512 communication protocol, does not need to additionally increase parameters to distinguish two modes, and effectively solves the problem that the lighting equipment is incompatible with two types of data on the premise of effectively saving communication protocol resources, thereby improving the light effect control effect of the lighting equipment. Specifically, the light efficiency control method provided by the embodiment of the application is that the light efficiency control method is installed in a light efficiency control device in a form of a computer program, the light efficiency control device is deployed in a lighting device in a form of a processor, and the light efficiency control device in the lighting device executes the light efficiency control method provided by the embodiment of the application by running the computer program corresponding to the light efficiency control method.
Specifically, as shown in fig. 2, fig. 2 is a schematic step flow diagram of a light efficiency control method according to an embodiment of the present application, and specifically includes steps S210 to S240:
s210, acquiring DMX protocol data transmitted by a DMX console.
In the embodiment of the present application, in combination with the implementation scenario of the light efficiency control method provided in the foregoing, it is known that the target lighting device generally performs data communication with the DMX console (typically, the DMX512 console) according to the agreed DMX protocol (typically, the DMX512 protocol), that is, the DMX console continuously sends the DMX protocol data carrying the light efficiency control parameters to the target lighting device. Of course, it should be noted that, according to the DMX512 protocol, the DMX protocol data transmitted by the DMX console generally further includes data content, but considering that the light efficiency control method provided by the embodiment of the present application only needs to use the light efficiency control parameter carried in the DMX protocol data, the embodiment of the present application does not specifically describe other data content carried in the DMX protocol data.
In the embodiment of the application, considering that the light efficiency control of the lighting equipment is mainly controlled based on angles of color, brightness, color temperature and the like, the light efficiency control parameters carried in the DMX protocol data generally comprise at least one of light color control parameters, light brightness control parameters and light color temperature control parameters. Of course, in general, the light efficiency control parameters include the above three control parameters at the same time, for example, in general DMX protocol data, the light efficiency control parameters generally include values R, G, B, WW of 5 channels and CW to describe the color, brightness, and color temperature of the lighting device, where R, G, B channel values form control of the color of the lighting device, WW channel values form control of the brightness of the lighting device, and CW channel values form control of the color temperature of the lighting device.
In addition, it should be noted that, the DMX protocol data transmitted by the DMX console is generally composed of consecutive data frames, that is, the target lighting device actually acquires different DMX protocol data continuously, and in the process of actually completing the light efficiency control, the lighting device needs to process each acquired DMX protocol data, so, for convenience of description, the following steps will be given by taking the current DMX protocol data acquired in real time as an example, and in the following embodiments, a complete control process for controlling the light efficiency of the lighting device is given.
S220, comparing the obtained target light efficiency control parameter in the current DMX protocol data with a preset reference light efficiency control parameter, and judging whether the target light efficiency control parameter is identical with the reference light efficiency control parameter. If not, step S230 is performed, and if not, the other steps are performed.
In the embodiment of the application, after the lighting device acquires new DMX protocol data, that is, current latest DMX protocol data, the following flow is executed: and comparing the target light efficiency control parameter carried in the DMX protocol data with a preset reference light efficiency control parameter to judge whether the target light efficiency control parameter and the preset reference light efficiency control parameter are identical. The reference light efficiency control parameter herein generally refers to a light efficiency control parameter in the DMX protocol data received last time. Specifically, in order to facilitate understanding, tn-1, tn, tn+1 are respectively used to represent the DMX protocol data received at the previous time, the DMX protocol data received at the current time, and the DMX protocol data received at the next time, at this time, the light efficiency control device in the lighting device compares the light efficiency control parameter of Tn in the current received DMX protocol data with the reference light efficiency control parameter, that is, the light efficiency control parameter in the DMX protocol data Tn-1 received at the previous time, so as to determine whether the two are the same, and further uses the light efficiency control parameter of Tn in the DMX protocol data as a new reference light efficiency control parameter, so that when the DMX protocol data tn+1 of the next time is received, the light efficiency control parameter in the DMX protocol data tn+1 of the next time is compared with the light efficiency control parameter of Tn in the DMX protocol data currently received, that is, the new reference light efficiency control parameter is compared.
In the embodiment of the present application, it is known from the foregoing description that, if the DMX console transmits DMX protocol data in a conventional light mode, the lighting device generally receives a series of DMX protocol data carrying the same light efficiency control parameter, whereas if the DMX console transmits DMX protocol data in a continuous light efficiency data mode, the lighting device generally receives a series of DMX protocol data carrying different light efficiency control parameters or only has a plurality of packets of the same DMX protocol data, so that, based on the variation characteristics of the light efficiency control parameter in the received DMX protocol data, the light efficiency control device in the lighting device can primarily identify the mode of the currently received DMX protocol data.
S230, obtaining the data frame number corresponding to the target light efficiency control parameter, and taking the target light efficiency control parameter as the updated reference light efficiency control parameter.
In the embodiment of the present application, if the target light efficiency control parameter in the current DMX protocol data is different from the reference light efficiency control parameter, it indicates that the light efficiency parameter of the target lighting device needs to be adjusted, but in the adjustment process, the light efficiency control device in the lighting device also counts the data frame number corresponding to the target light efficiency control parameter, and determines whether to perform light efficiency gradual change processing on the lighting device based on the data frame number. Specifically, the data frame number refers to the number of associated DMX protocol data in which the light efficiency control parameter is the same as the reference light efficiency control parameter in the acquired DMX protocol data, that is, when the light brightness control parameters for brightness control in the continuous 10 DMX protocol data received by the lighting device are all 20%, and when the light brightness control parameters for brightness control in the 11 th received DMX protocol data are adjusted to be 50%, the data frame number corresponding to the light efficiency control parameter is 10 at this time, that is, it is indicated that the light brightness control parameters in 10 packets of DMX protocol data in the DMX protocol data acquired in the past are all 20%.
Specifically, to facilitate recording the number of frames of data, the following may be used: a buff variable is predefined in a light efficiency controller of a target lighting device, when the lighting device receives DMX protocol data which is different from a light efficiency control parameter in the previous DMX protocol data each time, the buff variable is cleared and counted from 1, and when the lighting device receives DMX protocol data which is the same as the light efficiency control parameter in the previous DMX protocol data each time, the buff variable is increased by 1, namely, when the target light efficiency control parameter is the same as a reference light efficiency control parameter, the buff variable, namely, a data frame number corresponding to the target light efficiency control parameter, is updated. In this way, the number of data frames corresponding to the target light efficiency control parameter is recorded by the value of the buff variable.
Of course, in order to completely implement the light efficiency control algorithm logic provided by the embodiment of the present application, the target light efficiency control parameter in the currently acquired DMX protocol data is different from the preset reference light efficiency control parameter, and the target light efficiency control parameter is further used as the updated reference light efficiency control parameter for comparison of the next light efficiency control parameter, which is not described herein in detail.
S240, adjusting the light efficiency parameter of the target lighting equipment into a target light efficiency control parameter according to the light efficiency ramp time corresponding to the data frame number.
In the embodiment of the present application, in combination with the foregoing provided scheme, when the DMX console sends DMX protocol data in a continuous light effect data mode, at this time, the lighting device receives a series of DMX protocol data carrying different light effect control parameters, or only a plurality of packets of the same DMX protocol data, at this time, the number of data frames corresponding to the obtained target light effect control parameter is usually a smaller value, because each time the DMX protocol data carrying new different light effect control parameters is received, the number of data frames is cleared and counted from 1 again, so based on the number of data frames with a relatively smaller value, a relatively smaller light effect ramp time can be set, or no light effect ramp time (that is, the light effect ramp time is set to 0) is set, so as to adjust the light effect parameter of the target lighting device to the target light effect control parameter. Otherwise, if the DMX console transmits DMX protocol data in a conventional light mode, the lighting device generally receives a series of DMX protocol data carrying the same light efficiency control parameter, and at this time, the number of data frames corresponding to the obtained target light efficiency control parameter is generally accumulated to a higher value, so that a larger light efficiency ramp time can be set based on the number of data frames with a relatively higher value, so that the lighting device adjusts the light efficiency parameter to the target light efficiency control parameter in a light efficiency ramp manner. It can be seen that the data frame number and the light effect buffer time are generally in positive correlation, that is, the higher the data frame number is, the higher the corresponding light effect buffer time should be, so that when the lighting device receives the DMX protocol data in the conventional light mode, the adjustment of the light effect parameter can be completed according to the light effect buffer mode.
Based on the above description, as a possible embodiment of the present application, the association relationship between the number of data frames and the light effect buffer time may refer to fig. 3 and the explanation thereof. Specifically, as shown in fig. 3, fig. 3 is a schematic flow chart of a step of adjusting a light effect parameter based on a light effect ramp time corresponding to a data frame number according to an embodiment of the present application, and specifically includes steps S310 to S320:
and S310, if the number of data frames is smaller than a preset first frame number threshold, adjusting the light efficiency parameter of the target lighting equipment to be a target light efficiency control parameter according to the preset first light efficiency ramp time.
In the embodiment of the present application, if the number of frames of data is smaller than the first frame number threshold, it indicates that the target lighting device is more likely to receive continuous light efficiency data, for example, the frame number threshold may be set to 3, and at this time, the light efficiency control device may adjust the light efficiency parameter of the target lighting device to the target light efficiency control parameter according to a relatively smaller first light efficiency ramp time. For example, as a possible implementation, the first light effect ramp time may be 0, that is, the light effect parameter of the target lighting device is directly adjusted to the target light effect control parameter without performing the ramp process.
And S320, if the number of data frames is greater than a preset second frame number threshold, adjusting the light efficiency parameter of the target lighting equipment to be a target light efficiency control parameter according to the preset second light efficiency ramp time.
In the embodiment of the present application, if the number of data frames is greater than the second frame number threshold, it indicates that the target lighting device is more likely to receive DMX protocol data sent in the conventional light mode, for example, the frame number threshold may be set to 12, and at this time, the light efficiency control device may adjust the light efficiency parameter of the target lighting device to the target light efficiency control parameter according to a relatively greater second light efficiency ramp time, for example, as a possible implementation, the second light efficiency ramp time may be 350ms, that is, within the ramp time of 350ms, to gradually adjust the light efficiency parameter of the target lighting device to the target light efficiency control parameter.
Of course, if the number of data frames is between the first frame number threshold and the second frame number threshold, the light effect ramp time may be proportional to the number of data frames, specifically, the scaling factor may be set to 20, for example, when the number of data frames is 4, the corresponding light effect ramp time may be set to 80ms, and when the number of data frames is 8, the corresponding light effect ramp time may be set to 160ms. Specifically, in order to facilitate understanding of the above embodiment, a specific implementation scheme for adjusting the light efficiency parameter of the target lighting device to the target light efficiency control parameter according to the light efficiency ramp time corresponding to the data frame number is as follows:
If the number of data frames is less than 3, that is, if the buff variable is less than 3, the light efficiency control device directly adjusts the light efficiency parameter of the target lighting equipment to be the target light efficiency control parameter under the condition that the slow-change processing is not executed;
if the data frame number is greater than 12, that is, if the buff variable is greater than 12, the light efficiency control device gradually adjusts the light efficiency parameter of the target lighting equipment into the target light efficiency control parameter in the buffer time of 350 ms;
if the number of data frames is greater than or equal to 3 and less than or equal to 12, the light efficiency control device gradually adjusts the light efficiency parameters of the target lighting device into target light efficiency control parameters within the buffer time of 20 times of the number of data frames.
In the above implementation scheme, the thresholds 3 and 12 used for comparing the data frame numbers and the set light effect ramp time, for example, 0ms and 350ms, may be set by themselves based on actual requirements and the performance of the lighting device, and the setting of the parameters is not limited in this embodiment of the present application.
Further, in order to facilitate understanding of the implementation scheme provided by the embodiment of the present application for adjusting the light efficiency parameter of the target lighting device to the target light efficiency control parameter at the light efficiency ramp time, as shown in fig. 4, fig. 4 is a schematic flowchart of a step for adjusting the light efficiency parameter of the target lighting device to the target light efficiency control parameter at the light efficiency ramp time, which is provided by the embodiment of the present application, and specifically includes steps S410 to S430:
S410, acquiring a light efficiency control parameter difference value between the target light efficiency control parameter and the reference light efficiency control parameter.
In the embodiment of the application, when the light efficiency control parameter includes control parameters with multiple dimensions, such as color, brightness, color temperature and the like, the light efficiency control parameter differences, such as color difference, brightness difference and color temperature difference, of the target light efficiency control parameter and the reference light efficiency control parameter in different dimensions can be obtained by making differences between the target light efficiency control parameter and the control parameter of the corresponding channel in the reference light efficiency control parameter, and similar control processing is executed on the light efficiency parameter differences of the target lighting equipment for each dimension. Specifically, for ease of understanding, the embodiments of the present application are described only by taking control in the brightness dimension as an example, and when the brightness of the lighting device needs to be adjusted from 20% to 50%, the difference between the light efficiency control parameters is 30%.
S420, determining the light efficiency control parameters of the target lighting equipment at all moments according to the light efficiency buffer time corresponding to the data frame number and the light efficiency control parameter difference value.
In the embodiment of the application, after the light effect slowly-changing time of the lighting equipment for completing the light effect control is determined, the light effect control parameters of the target lighting equipment corresponding to all moments can be determined based on the light effect control parameter difference value. For example, taking the above-determined light efficiency ramp time as 300ms as an example, consider that in a normal case, the light efficiency update frequency of the lighting device is 10ms, that is, the target lighting device needs to adjust the light efficiency control parameter of the target lighting device from 20% to 50% after 30 light efficiency updates, that is, the variable adjusted by each light efficiency update is 1%, that is, the brightness of the target lighting device needs to be increased by 1% every 10ms in a subsequent time. Of course, the above-mentioned data are described by taking the light efficiency update frequency of the lighting device as 10ms as an example, and in fact, the light efficiency update frequency of the lighting device may be determined by the performance of the lighting device, and the embodiment of the present application is not limited herein.
And S430, controlling the target lighting equipment according to the light efficiency control parameters of the target lighting equipment at each moment so as to adjust the light efficiency parameters of the target lighting equipment into target light efficiency control parameters.
In the embodiment of the application, after the light efficiency control parameters of the target lighting equipment corresponding to each moment are obtained, the target lighting equipment is controlled in sequence according to the light efficiency control parameters of the target lighting equipment corresponding to each moment, so that the light efficiency parameters of the target lighting equipment can be adjusted to the target light efficiency control parameters within a given light efficiency slowly-changing time.
In addition, when the light effect ramp time is short and the light effect control parameter difference is large, the variable adjusted by the lighting device during each time of light effect update is large, so that the lighting device is easy to flicker, in order to solve the problem, after the light effect control parameter difference and the light effect ramp time are obtained, the ratio of the light effect control parameter difference to the light effect ramp time is used to determine whether the lighting device flickers, specifically, as shown in fig. 5, fig. 5 is a schematic flow chart of steps for adjusting the light effect parameter of the lighting device based on the light effect control parameter difference and the light effect ramp time, which specifically includes steps S510 to S530:
S510, calculating the ratio of the light effect control parameter difference value to the light effect ramp time, and judging whether the ratio is smaller than a preset ratio threshold value. If yes, step S520 is executed, and if no, step S530 is executed:
in the embodiment of the application, the ratio of the light effect control parameter difference value to the light effect slow-change time describes the change amplitude of the lighting equipment required to be changed when the light effect is changed each time, and whether the change amplitude can bring the flicker abnormal experience to the user can be determined by judging the ratio and the preset ratio threshold value. In particular, the ratio threshold may be set based on the lighting performance of the lighting device, for example, in a normal case, the ratio threshold may be set to 5%, i.e. the brightness may not change by more than 5% every update of the lighting device, i.e. every 10 ms.
S520, determining the light efficiency control parameters of the target lighting equipment at all moments according to the light efficiency buffer time corresponding to the data frame number and the light efficiency control parameter difference value.
In the embodiment of the present application, when the obtained ratio is smaller than the preset ratio threshold, that is, when the change amplitude of the lighting device required to change when the light efficiency changes each time does not bring the flicker abnormal experience to the user, the light efficiency control device determines the light efficiency control parameters of the target lighting device corresponding to each time according to the light efficiency slow change time and the light efficiency control parameter difference, and then completes the control of the lighting device according to the light efficiency control parameters of the target lighting device corresponding to each time, that is, executes the steps S420 and S430.
And S530, controlling the target lighting equipment according to the preset maximum allowable parameter difference value so as to adjust the light efficiency parameter of the target lighting equipment into a target light efficiency control parameter.
In the embodiment of the application, when the obtained ratio is greater than the preset ratio threshold, that is, the change amplitude of the lighting equipment required to be changed is greater when the light efficiency is changed each time, the lighting equipment can bring the flickering abnormal experience to the user, and the light efficiency control device can control the target lighting equipment according to the preset maximum allowable parameter difference. For example, when the foregoing calculation determines that the brightness of the required change at each update of the lighting device is 8%, i.e., greater than 5% of the maximum allowable change range of the change at each update, the lighting device adjusts the lighting efficiency parameter of the target lighting device according to the maximum allowable parameter difference, i.e., according to the 5% brightness change range every 10ms, until the final target lighting efficiency control parameter is obtained.
According to the light efficiency control method provided by the embodiment of the application, after the lighting equipment acquires the DMX protocol data which is transmitted by the DMX console and carries the light efficiency control parameter, the target light efficiency control parameter in the acquired current DMX protocol data is compared with the preset reference light efficiency control parameter in real time, if the target light efficiency control parameter and the preset reference light efficiency control parameter are different, the corresponding light efficiency gradual change time is set according to the quantity of the associated DMX protocol data with the same light efficiency control parameter in the previously acquired DMX protocol data, so that the light efficiency parameter adjustment of the target lighting equipment is completed.
Of course, besides setting the light effect ramp time by the light effect control method provided by the embodiment of the application to complete the adjustment of the light effect parameter of the target lighting device, in fact, the DMX protocol data transmitted by the DMX console may also include a ramp time parameter, at this time, if the DMX protocol data transmitted by the DMX console includes the ramp time parameter, the adjustment of the light effect parameter of the target lighting device is completed according to the ramp time parameter carried in the DMX protocol data, otherwise, if the DMX protocol data transmitted by the DMX console does not carry the ramp time parameter, the adjustment of the light effect parameter of the target lighting device is completed according to the light effect control method provided by the embodiment of the application. Specifically, as shown in fig. 6, fig. 6 is a schematic step flow diagram of another light efficiency control method provided by the embodiment of the present application, and specifically, compared with the light efficiency control method shown in fig. 2, the method further includes steps S610 to S630:
s610, acquiring the DMX protocol data transmitted by the DMX console, and judging whether the DMX protocol data carries a slow-change time parameter. If yes, step S620 is executed, and if no, step S630 is executed.
The light effect control method provided by the embodiment of the application is implemented under the condition that the DMX protocol data only provides the light effect control parameters to save communication resources, and in fact, the control method does not conflict with the conventional protocol control method. That is, in fact, the ramp time parameter may also be provided according to a protocol convention in the DMX protocol data, and of course, the ramp time parameter provided in the DMX protocol data needs to occupy a certain communication resource, so before executing the light effect control method provided in the embodiment of the present application, the light effect control device determines whether the protocol data carries the ramp time parameter after acquiring the DMX protocol data transmitted by the DMX console, thereby determining whether to control the lighting device according to the light effect control method provided in the embodiment of the present application or complete the control of the lighting device based on the data in the protocol.
S620, adjusting the light efficiency parameter of the target lighting equipment into the target light efficiency control parameter carried by the DMX protocol data according to the slowly-varying time parameter.
In the embodiment of the application, when the DMX protocol data carries the time-varying time parameter, at this time, the light efficiency control device directly adjusts the light efficiency parameter of the target lighting equipment to the target light efficiency control parameter carried by the DMX protocol data according to the time-varying time parameter carried by the DMX protocol data, so as to omit the light efficiency control method provided by the embodiment of the application, thereby providing a more accurate light efficiency control effect.
S630, comparing the obtained target light efficiency control parameter in the current DMX protocol data with a preset reference light efficiency control parameter.
In the embodiment of the application, when the DMX protocol data does not carry the time delay parameter, the light effect control device executes the light effect control method provided by the embodiment of the application, and compares the target light effect control parameter in the DMX protocol data with the preset reference light effect control parameter to determine the data type of the currently received DMX protocol data, thereby facilitating the follow-up completion of the light effect parameter adjustment of the target lighting equipment according to the light effect time delay corresponding to the data frame number. Specifically, the explanation of step S630 may refer to the aforementioned step S220, and the embodiments of the present application are not repeated here.

8) Acquiring a light efficiency control parameter difference value between a target light efficiency control parameter and a reference light efficiency control parameter;
