[0001] The present invention relates to the technical field of stage lighting control, and in particular to a stage lighting control method based on Internet of Things technology. Background Art

[0002] In the field of modern stage performing arts, stage lighting plays an important role in creating atmosphere, guiding the audience's visual focus, and enhancing artistic presentation. Therefore, the precision and instant response of stage lighting control are crucial to improving the overall visual effect of the performance.

[0003] However, traditional stage lighting control methods mainly rely on manual operation and preset programs. Although they can achieve a certain degree of lighting control, their efficiency is relatively low and they lack the ability to respond to changes in the environment and lighting equipment in real time. In the actual use of stage lighting, the interference and changes in environmental conditions often affect the precise display of lights. When faced with these problems, current traditional control methods often find it difficult to make accurate judgments and analyses, and are even unable to effectively and automatically monitor and control the performance status of lighting equipment.

[0004] In order to solve the above-mentioned defects, a technical solution is now provided. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that traditional stage lighting control methods are too limited and single, and cannot respond to changes in the environment and lighting equipment in real time, and to propose a stage lighting control method based on Internet of Things technology.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A stage lighting control method based on Internet of Things technology includes the following steps:

[0008] By analyzing and processing the display status of stage lights, the display effect level is obtained;

[0009] Based on the display effect level, which is an abnormal display effect level, the environmental state of the stage lighting is analyzed and processed to obtain a real-time interference value of the environment in which the stage lighting is located, thereby determining the environmental interference level, and the environmental interference level includes a mild environmental interference level, a moderate environmental interference level, and a severe environmental interference level;

[0010] If the environmental interference level of the stage lighting environment is a moderate environmental interference level or a severe environmental interference level, the environmental detection and control command is triggered;

[0011] If the environmental interference level of the stage lighting environment is a mild environmental interference level, the lighting equipment detection and control instructions are triggered;

[0012] According to the triggered environmental detection and control instructions, the environmental status information of the stage lights is retrieved and analyzed to obtain the dimming signal and temperature control signal;

[0013] According to the triggered lighting equipment detection and control instructions, the performance status of the lighting equipment is analyzed and processed to obtain current abnormality signals and flicker abnormality signals;

[0014] According to the dimming signal, temperature control signal, current abnormality signal and stroboscopic abnormality signal, the stage lighting environment and the performance of the lighting equipment are regulated and processed, and the verification mechanism is triggered after the regulation and processing is completed;

[0015] According to the triggered verification mechanism, the control effect of the stage lighting is verified and analyzed, and a control verification pass signal or a control verification fail signal is obtained.

[0016] Furthermore, the display status of the stage lights is analyzed and processed. The specific process is as follows:

[0017] According to the display area status of the stage lights, the display area status is indoor or outdoor. If it is indoor, the indoor area is marked as the monitoring area. If it is outdoor, a circular area with a preset radius R is drawn with the stage as the center and marked as the monitoring area.

[0018] By obtaining the number of abnormal display times of stage lights in the monitoring area , spot uniformity and color rendering value , according to the set calculation model: , thereby obtaining the display effect evaluation value of the stage lighting in the monitoring area

[0019] in, and Respectively represent the reference display abnormality times, reference light spot uniformity and reference color rendering value, and They represent the allowable difference of the number of display abnormalities, the allowable difference of the uniformity of the light spot and the allowable difference of the color rendering. and are the normalization factors for the number of abnormal display times, spot uniformity, and color rendering value, respectively. is the correction factor coefficient in the calculation model;

[0020] The number of abnormalities displayed is the number of abnormalities of the stage lighting;

[0021] The spot uniformity value is determined by collecting the brightness data of the light projected in the spot area, and calculating the brightness uniformity of the entire spot area based on the collected brightness data;

[0022] The color rendering value is determined by calculating and analyzing the difference between the color of the object under the light source and the color of the standard color plate to obtain the color difference value;

[0024] Furthermore, the environmental status of the stage lighting is analyzed and processed. The specific process is as follows:

[0025] By obtaining the luminous flux value in the environmental status information of the stage lighting Temperature value , according to the set data model: , get the real-time interference value of the stage lighting environment ;

[0026] in, represents a natural constant, and Respectively represent the weight coefficients of luminous flux value and temperature value;

[0027] The luminous flux value refers to the total amount of light emitted by the environment in which the stage lighting is located per unit time, which measures the brightness intensity of the light source in the environment. The temperature value refers to the average temperature of the environment in which the stage lighting is located.

[0028] Furthermore, the environmental status information of the stage lighting is retrieved for analysis. The specific process is as follows:

[0029] Retrieving the luminous flux value and temperature value in the environmental status information of the stage lighting, performing difference calculations on the luminous flux value and the temperature value respectively with the reference luminous flux value and the reference temperature value, and taking the absolute values to obtain the luminous flux deviation value and the temperature deviation value, and comparing the luminous flux deviation value and the temperature deviation value with the preset luminous flux deviation threshold value and the temperature deviation threshold value respectively;

[0030] If the luminous flux deviation value is greater than a preset luminous flux deviation threshold, a dimming signal is generated;

[0031] If the temperature deviation value is greater than the preset temperature deviation threshold, a temperature adjustment signal is generated.

[0032] Furthermore, the performance status of the lighting equipment is analyzed and processed. The specific process is as follows:

[0033] By detecting the current signal of the lighting device, the current signal of the lighting device is obtained, and based on the current signal, a current waveform diagram of the lighting device is generated by using designated software to obtain the current waveform diagram of the lighting device;

[0034] At the same time, a reference current waveform of the lighting device is extracted from the system repository, and the current waveform of the lighting device is overlapped and compared with the reference current waveform to obtain the overlap waveform length of the lighting device. The overlap waveform length of the lighting device is then compared and analyzed with a preset overlap waveform length threshold. If the overlap waveform length of the lighting device is less than the preset overlap waveform length threshold, a current abnormality signal is generated.

[0035] By obtaining the number of flicker times of the lighting device and comparing it with the preset flicker threshold, if the flicker time of the lighting device is greater than the preset flicker threshold, a flicker abnormality signal is generated.

[0036] Furthermore, the environment in which the stage lights are located is regulated and processed. The specific process is as follows:

[0037] Based on the generated dimming signal, the luminous flux deviation value of the environment in which the stage lights are located is retrieved and matched with the stored luminous flux deviation state table for analysis, thereby obtaining the luminous flux deviation level of the environment in which the stage lights are located. At the same time, the luminous flux deviation level is matched with the lighting control parameters corresponding to the luminous flux deviation level to obtain the lighting control parameters of the stage lights, thereby completing the dimming process;

[0038] According to the generated temperature control signal, the temperature deviation value of the environment in which the stage lights are located is retrieved as the temperature influence factor of the environment in which the stage lights are located, a preset temperature value of the environment in which the stage lights are located is set, and the preset temperature value of the environment in which the stage lights are located is calculated and processed with the temperature influence factor to obtain a final control reference temperature value of the environment in which the stage lights are located;

[0039] Obtain the actual temperature value of the environment in which the stage lights are located, and compare the actual temperature value of the environment in which the stage lights are located with the final control reference temperature value;

[0040] When the actual temperature value of the environment where the stage lighting is located is greater than the final control reference temperature value, a cooling signal is generated, and the actual temperature value is adjusted down to the same as the final control reference temperature value according to the generated cooling signal;

[0041] When the actual temperature value of the environment in which the stage lighting is located is lower than the final control reference temperature value, a temperature increase signal is generated. Based on the generated temperature increase signal, the actual temperature value is increased to be consistent with the final control reference temperature value, thereby completing the temperature control process.

[0042] Furthermore, the performance of the lighting equipment is regulated and processed. The specific process is as follows:

The distribution state of the harmonics in the frequency domain is determined based on the power spectrum density. The distribution state of the harmonics in the frequency domain is compared and matched with the stored filter determination table, thereby matching the corresponding filter, applying the selected filter to the signal, and converting the signal processed by the filter from the frequency domain back to the time domain, thereby obtaining a signal after eliminating the harmonics, and thus completing the wave reduction processing;

[0044] According to the generated abnormal flicker signal, the number of flickers is retrieved and substituted into the corresponding preset value range. Different value ranges are set to correspond to a performance control parameter respectively, and the performance control parameter of the lighting equipment is obtained, thereby completing the flicker reduction process.

[0045] Furthermore, the control effect of stage lighting is verified and analyzed. The specific process is as follows:

[0046] When the display effect level of the stage lights in the monitoring area is abnormal, and after the optimization process of the environment in which the stage lights are located is completed, the display status information of the stage lights is monitored in real time, thereby generating an evaluation value of the control display effect of the stage lights in the monitoring area;

[0047] Comparing and matching the control display effect evaluation value of the stage lights in the monitoring area with the stored control display effect state determination table, thereby obtaining the control display effect level of the stage lights in the monitoring area, and the control display effect level includes the control normal display effect level and the control abnormal display effect level;

[0048] If the output result of regulating the display effect level is regulating the normal display effect level, a regulation verification pass signal is generated;

[0049] If the output result of regulating the display effect level is regulating an abnormal display effect level, a lighting equipment detection and regulation instruction is generated;

[0050] When the display effect level of the stage lights in the monitoring area is abnormal, and after the environmental control processing of the stage lights and the performance control processing of the lighting equipment are completed, the control display effect evaluation value and the control display effect level of the stage lights in the monitoring area are obtained;

[0051] If the output result of regulating the display effect level is regulating the normal display effect level, a regulation verification pass signal is generated;

[0052] If the output result of the control display effect level is the control abnormal display effect level, a control verification failure signal is generated, and the corresponding control processing is returned again.

[0054] 1. The present invention determines and analyzes the display status of stage lights to achieve accurate judgment of the lighting display effect. Based on this, it further retrieves information about the environmental status of the stage lights and adopts data model calculation and database comparison analysis to effectively analyze and determine whether environmental interference factors have caused the unsatisfactory stage lighting display status. Based on the analysis results, different detection and control instructions are intelligently triggered to perform precise environmental interference detection and lighting equipment performance detection and control, thereby achieving accurate judgment and intelligent control of stage lighting display effects, providing strong technical support and guarantee for stage art performance.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0059] like Figure 1 As shown, a stage lighting control method based on Internet of Things technology includes the following steps:

[0060] Step 1: Monitor the display status information of the stage lights, and analyze and process the display status of the stage lights. The specific analysis process is as follows:

[0061] According to the display area status of the stage lights, the display area status is indoor or outdoor. If it is indoor, the indoor area is marked as the monitoring area. If it is outdoor, a circular area with a preset radius R is drawn with the stage as the center and marked as the monitoring area.

[0062] By obtaining the display abnormality times, spot uniformity and color rendering value of the stage lights in the monitoring area, and calibrating them as and , according to the set calculation model: , thereby obtaining the display effect evaluation value of the stage lighting in the monitoring area ,in, and Respectively represent the reference display abnormality times, reference light spot uniformity and reference color rendering value, and They represent the allowable difference of display abnormality times, the allowable difference of light spot uniformity and the allowable difference of color rendering. and are the normalization factors of the number of display anomalies, the uniformity of the light spot, and the color rendering value, respectively, and and are all natural numbers greater than 0. The normalization factor is used to represent the coefficient that converts the data in the calculation model into dimensionless form. is the correction factor coefficient in the calculation model, and It is a natural number greater than 0. The correction factor coefficient is used to correct the deviation of the parameters in the calculation process, so as to make the calculation of parameter data more accurate.

[0063] In the embodiment of the present invention, the number of display anomalies refers to the number of times stage lighting anomalies occur; the spot uniformity value refers to an indicator that measures the uniformity of the brightness distribution in the light projection area. Specifically, the solution is: using a photometer to collect brightness data of the light projection in the spot area, and based on the collected brightness data, calculate the brightness distribution of the entire spot area according to the formula: , get the uniform value of the spot ,in, Indicates brightness uniformity, Represents the brightness value of each sampling point, Represents the average brightness of the spot area, Indicates the number of the sampling point, Indicates the total number of sampling points; the color rendering value refers to the accuracy of the light source's rendering of the object's color. The specific solution is: select multiple objects, calculate and analyze the difference between the color of the object under the light source and the color of the standard color palette, according to the CIE1976 color difference formula: , get the color value ,in, and Indicates the chromaticity value of an object under the illumination of a light source (calculated according to the CIE color space model). and Indicates the chromaticity value of the standard object under ideal conditions. represents the number of the object, m represents the total number of objects, Indicates the color difference value, which reflects the degree of deviation between the color of the object under the illumination of the light source and the standard color. The smaller the color difference value, the more accurate the color restoration;

[0064] It should be pointed out that in the CIE1976 color difference formula, and The three chromaticity coordinates representing the color are defined according to the CIE1976 (Lab) color space model;

[0065] The display effect evaluation value of the stage lights in the monitoring area is compared and matched with the display effect status determination table stored in the cloud database to obtain the display effect level of the stage lights in the monitoring area. The display effect evaluation value of the stage lights in each monitoring area corresponds to a display effect level, and the display effect level includes a normal display effect level and an abnormal display effect level.

[0066] Step 2: Based on the obtained display effect level, the display effect level is an abnormal display effect level, which is used to monitor the environmental status information of the stage lighting, thereby analyzing and processing the environmental status of the stage lighting. The specific analysis process is as follows:

[0067] By obtaining the luminous flux value and temperature value in the environmental state information of the stage lighting, and marking them as and And analyze the data according to the set data model: , get the real-time interference value of the stage lighting environment ,in, represents a natural constant, and Represent the weight coefficients of luminous flux value and temperature value respectively, and and Are greater than The weight coefficient is a natural number, and is used to balance the weight of each data in the formula calculation, thereby improving the accuracy of the calculation results;

[0068] In the embodiment of the present invention, the luminous flux value refers to the total amount of light emitted per unit time by the environment in which the stage lights are located, and measures the brightness intensity of the light source in the environment. The temperature value refers to the average temperature of the environment in which the stage lights are located.

[0069] It should be noted that the color temperature of the light source will change with temperature. For example, the color temperature of an incandescent lamp may be yellowish at lower temperatures and bluish at higher temperatures. The color temperature of an LED lamp may also fluctuate as the temperature rises, resulting in unstable colors.

[0070] The real-time interference value of the environment in which the stage lights are located is compared and matched with the environmental interference level determination table stored in the cloud database to obtain the environmental interference level of the environment in which the stage lights are located. The real-time interference value of each stage light's environment corresponds to an environmental interference level, and the environmental interference levels include a mild environmental interference level, a moderate environmental interference level, and a severe environmental interference level.

[0071] Step 3: If the output result of the environment in which the stage lighting is located is a moderate environmental interference level or a severe environmental interference level, the environmental detection and control instruction is triggered. Based on the triggered environmental detection and control instruction, the environmental status information of the stage lighting is retrieved for analysis. The specific analysis is as follows:

[0072] Retrieving the luminous flux value and temperature value in the environmental status information of the stage lighting, performing difference calculations on the luminous flux value and the temperature value respectively with the reference luminous flux value and the reference temperature value, and taking the absolute values to obtain the luminous flux deviation value and the temperature deviation value, and comparing the luminous flux deviation value and the temperature deviation value with the preset luminous flux deviation threshold value and the temperature deviation threshold value respectively;

[0073] If the luminous flux deviation value is greater than a preset luminous flux deviation threshold, a dimming signal is generated;

[0074] If the temperature deviation value is greater than the preset temperature deviation threshold, a temperature adjustment signal is generated;

[0075] If the output result of the environment in which the stage lighting is located is a light environmental interference level, the lighting equipment detection and control instruction is triggered.

[0076] Step 4: Based on the dimming signal and temperature control signal, the stage lighting environment is regulated and analyzed. The specific analysis process is as follows:

[0077] Based on the generated dimming signal, the luminous flux deviation value of the environment in which the stage lights are located is retrieved and matched and analyzed with the luminous flux deviation state table stored in the cloud database, thereby obtaining the luminous flux deviation level of the environment in which the stage lights are located. Each luminous flux deviation value of the environment in which the stage lights are located corresponds to a luminous flux deviation level. At the same time, the luminous flux deviation value is matched with the lighting control parameters corresponding to the luminous flux deviation level to obtain the lighting control parameters of the stage lights. The lighting control parameters include but are not limited to brightness, color temperature, and beam angle, thereby completing the dimming process;

[0078] According to the generated temperature control signal, the temperature deviation value of the environment where the stage lighting is located is retrieved as the temperature influencing factor of the environment where the stage lighting is located. , set the preset temperature value of the stage lighting environment , set the preset temperature value of the stage lighting environment Temperature influence factor Perform calculations according to the formula: , get the final control reference temperature value of the stage lighting environment ;

[0079] By obtaining the actual temperature value of the environment where the stage lighting is located , the measured temperature value of the environment where the stage lighting is located and the final control reference temperature value For comparison, when the actual temperature value of the stage lighting environment Greater than the final control reference temperature value When the temperature drops, a cooling signal is generated, and the measured temperature value is converted to Adjust down to the final control reference temperature value Consistent, when the actual temperature value of the stage lighting environment Less than the final control reference temperature value When the temperature rises, a temperature rise signal is generated, and the measured temperature value is converted to Adjust to the final control reference temperature value Consistent, thus completing the temperature adjustment process;

[0080] After the light adjustment process and the temperature adjustment process are completed, step six is executed.

[0081] Step 5: Based on the triggered lighting equipment detection and control instructions, the performance status information of the lighting equipment is monitored, and the performance status of the lighting equipment is analyzed and processed accordingly. The specific analysis steps are as follows:

[0082] The current signal of the lighting device is detected by a current sensor to obtain the current signal of the lighting device, and based on the current signal, a current waveform diagram of the lighting device is generated by designated software to obtain the current waveform diagram of the lighting device; wherein the designated software is specifically current analysis software;

[0083] At the same time, a reference current waveform of the lighting device is extracted from the system repository, and the current waveform of the lighting device is overlapped and compared with the reference current waveform to obtain the overlap waveform length of the lighting device. The overlap waveform length of the lighting device is then compared and analyzed with a preset overlap waveform length threshold. If the overlap waveform length of the lighting device is less than the preset overlap waveform length threshold, a current abnormality signal is generated.

[0084] Based on the generated abnormal current signal, the time domain signal containing harmonics in the current signal is extracted, and the time domain signal containing harmonics is converted to the frequency domain using Fourier transform (such as fast Fourier transform, FFT), and the power spectral density of the harmonics is estimated. The power spectral density is used to describe the energy distribution of the signal on each frequency component, helping to identify the intensity of the harmonic components and their frequency distribution. The distribution state of the harmonics in the frequency domain is determined based on the power spectral density. The distribution state of the harmonics in the frequency domain is compared and matched with the filter determination table stored in the cloud database, thereby matching the corresponding filter. Each distribution state of the harmonics in the frequency domain corresponds to a type of filter. The selected filter is applied to the signal, and the signal processed by the filter is converted from the frequency domain back to the time domain, thereby obtaining a signal after the harmonics are eliminated, and thus completing the wave reduction processing;

[0085] By obtaining the number of flicker times of the lighting device and comparing it with the preset flicker threshold, if the flicker time of the lighting device is greater than the preset flicker threshold, a flicker abnormality signal is generated. According to the generated flicker abnormality signal, the flicker time is retrieved and substituted into the corresponding preset value range. Different value ranges are set to correspond to a performance control parameter, and the performance control parameter of the lighting device is obtained. The performance control parameter includes but is not limited to PWM frequency, power frequency, and brightness, thereby completing the flicker reduction process;

[0086] It should be noted that harmonics refer to the integer multiple frequency components in the signal other than the fundamental frequency. In stage lighting equipment, harmonics will have a negative impact on the color temperature and color performance of the light, resulting in color distortion or inconsistency. In addition, harmonics will cause fluctuations in the brightness of the light source, thereby affecting the luminous flux of the stage lighting. This fluctuation not only makes the lighting effect unstable, but may also shorten the service life of the equipment.

[0087] Stroboscopic lighting refers to the periodic change in the brightness of lighting equipment, which manifests as flickering or unstable brightness output. Stroboscopic lighting can adversely affect the audience's visual perception, causing eye fatigue or discomfort. During stage performances, stroboscopic lighting can disrupt the stability of the lighting, affect the presentation of stage effects, and reduce the artistic effect. In addition, stroboscopic lighting can interfere with other electronic equipment on the stage, affecting their normal operation and thus disrupting the overall coordination and smoothness of the performance.

[0088] After completing the wave reduction processing and the flash reduction processing, execute step 6.

[0089] Step 6: Verify and analyze the control effect of stage lighting. The specific analysis process is as follows:

[0090] When the display effect level of the stage lights in the monitoring area is abnormal, and after the optimization of the environment in which the stage lights are located is completed, the display status information of the stage lights is monitored in real time, thereby generating an evaluation value of the control display effect of the stage lights in the monitoring area. , specifically, according to the set model: ,in, and Respectively represent the number of display abnormalities, light spot uniformity and color rendering value under control. and are the normalization factors of the regulated display abnormality times, light spot uniformity and color rendering value, and and They are all natural numbers greater than 0. The normalization factor is used to represent the coefficient that converts the data in the calculation model into dimensionless form;

[0091] The control display effect evaluation value of the stage lights in the monitoring area is compared and matched with the control display effect state determination table stored in the cloud database, thereby obtaining the control display effect level of the stage lights in the monitoring area, and each obtained control display effect evaluation value of the stage lights in the monitoring area corresponds to a control display effect level, and the control display effect level includes a normal control display effect level and an abnormal control display effect level;

[0092] If the output result of regulating the display effect level is regulating the normal display effect level, a regulation verification pass signal is generated and displayed on the display terminal;

[0093] If the output result of regulating the display effect level is regulating an abnormal display effect level, a lighting equipment detection and regulation instruction is generated;

[0094] When the display effect level of the stage lights in the monitoring area is abnormal, and after the environmental control processing of the stage lights and the performance control processing of the lighting equipment are completed, the control display effect evaluation value and the control display effect level of the stage lights in the monitoring area are obtained;

[0095] If the output result of regulating the display effect level is regulating the normal display effect level, a regulation verification pass signal is generated and displayed on the display terminal;

[0096] If the output result of the control display effect level is the control abnormal display effect level, a control verification failure signal is generated, and the control process is returned to be performed again;
