By obtaining the display abnormality times, spot uniformity and color rendering value of the stage lights in the monitoring area, and calibrating them as Xyc, Xgb and Xxs respectively, according to the set calculation model: , thus obtaining the display effect evaluation value XS of the stage lighting in the monitoring area display ,in, and denote the reference display abnormality times, the reference light spot uniformity value and the reference color rendering value respectively, ΔXyc, ΔXgb and ΔXxs denote the allowable difference of the display abnormality times, the allowable difference of the light spot uniformity and the allowable difference of the color rendering respectively, a1, a2 and a3 are the normalization factors of the display abnormality times, the light spot uniformity value and the color rendering value respectively, and a1, a2 and a3 are all natural numbers greater than 0, the normalization factor is used to represent the coefficient for converting each data in the calculation model into a dimensionless form, η is the correction factor coefficient in the calculation model, and η 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 calculate more accurate parameter data; In the embodiment of the present invention, the number of abnormal display times refers to the number of abnormal stage lighting; the spot uniformity value refers to an indicator for measuring the uniformity of the brightness distribution in the light projection area, which is specifically solved as follows: the brightness data of the light projection in the spot area is collected by a photometer, and the brightness distribution of the entire spot area is calculated based on the collected brightness data, according to the formula: , get the spot uniform value Xgb, where σ light Indicates brightness uniformity, I i Represents the brightness value of each sampling point, It represents the average brightness of the spot area, i represents the number of the sampling point, and n represents the total number of sampling points. The color rendering value refers to the accuracy of the light source in presenting the color of the object. 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 plate, according to the CIE1976 color difference formula: , get the color value Xxs, where and Indicates the chromaticity value of an object under the illumination of a light source (calculated according to the CIE color space model). and represents the chromaticity value of the standard object under ideal conditions, k represents the number of the object, m represents the total number of objects, ΔE k Indicates the color difference value, which reflects the degree of deviation between the color of the object and the standard color under the illumination of the light source. The smaller the color difference value, the more accurate the color restoration; 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; 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, thereby obtaining the display effect level of the stage lights in the monitoring area, and 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.

[0018] Step 2: Based on the obtained display effect level, the environmental status information of the stage lighting is monitored, and the environmental status of the stage lighting is analyzed and processed. The specific analysis process is as follows: By obtaining the luminous flux value and temperature value in the environmental status information of the stage lighting, marking them as Hgt and Hws respectively, and analyzing the data, according to the set data model: , get the real-time interference value HJ of the environment where the stage lighting is located environ , where e represents a natural constant, b1 and b2 represent the weight coefficients of the luminous flux value and the temperature value respectively, and b1 and b2 are both natural numbers greater than 0, and the weight coefficient is used to balance the weight of each data in the formula calculation, thereby promoting the accuracy of the calculation result; In the embodiment of the present invention, the luminous flux value refers to the total amount of light emitted by the environment where the stage light is located per unit time, which measures the brightness intensity of the light source in the environment, and the temperature value refers to the average temperature of the environment where the stage light is located; It should be pointed out 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 a lower temperature, and blue at a higher temperature. The color temperature of an LED lamp may also fluctuate as the temperature rises, resulting in unstable colors. 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, thereby obtaining the environmental interference level of the environment in which the stage lights are located, and each real-time interference value of the environment in which the stage lights are located corresponds to an environmental interference level, and the environmental interference levels include mild environmental interference level, moderate environmental interference level and severe environmental interference level.

[0019] Step 3: If the output result of the environment where the stage light is located is a moderate environmental interference level or a severe environmental interference level, the environmental detection and control instruction is triggered. According to the triggered environmental detection and control instruction, the environmental status information of the stage light is retrieved for analysis. The specific analysis is as follows: Retrieving the luminous flux value and temperature value in the environmental state information of the stage lighting, performing difference calculations with the reference luminous flux value and the reference temperature value respectively and taking absolute values, obtaining 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; If the luminous flux deviation value is greater than a preset luminous flux deviation threshold, a dimming signal is generated; If the temperature deviation value is greater than the preset temperature deviation threshold, a temperature adjustment signal is generated; 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 instructions are triggered.

[0020] Step 4: Based on the dimming signal and the temperature control signal, the environment in which the stage lighting is located is regulated and analyzed. The specific analysis process is as follows: According to the generated dimming signal, the luminous flux deviation value of the environment where the stage light is located is retrieved, and the luminous flux deviation value is 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 where the stage light is located, and each luminous flux deviation value of the environment where the stage light is located corresponds to a luminous flux deviation level, and at the same time, it is matched with the lighting control parameters corresponding to the luminous flux deviation level to obtain the lighting control parameters of the stage light, and the lighting control parameters include but are not limited to brightness, color temperature, and beam angle, thereby completing the dimming process; According to the generated temperature control signal, the temperature deviation value of the environment where the stage light is located is retrieved as the temperature influence factor WDY of the environment where the stage light is located, the preset temperature value WYS of the environment where the stage light is located is set, and the preset temperature value WYS of the environment where the stage light is located is calculated and processed with the temperature influence factor WDY according to the formula: , get the final control reference temperature value MBW of the environment where the stage lighting is located; By obtaining the actual temperature value SCW of the environment where the stage light is located, the actual temperature value SCW of the environment where the stage light is located is compared with the final control reference temperature value MBW. When the actual temperature value SCW of the environment where the stage light is located is greater than the final control reference temperature value MBW, a cooling signal is generated. According to the generated cooling signal, the actual temperature value SCW is adjusted down to be consistent with the final control reference temperature value MBW. When the actual temperature value SCW of the environment where the stage light is located is less than the final control reference temperature value MBW, a heating signal is generated. According to the generated heating signal, the actual temperature value SCW is adjusted up to be consistent with the final control reference temperature value MBW, thereby completing the temperature control process; After the dimming process and the temperature adjustment process are completed, step six is ​​executed.

[0021] 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: 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 a designated software to obtain the current waveform diagram of the lighting device; wherein the designated software is specifically a current analysis software; 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, and the overlap waveform length of the lighting device is 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; According to 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 spectrum density of the harmonics is estimated. The power spectrum 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, and 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 filter determination table stored in the cloud database, thereby matching the corresponding filter, and 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 the wave reduction processing is completed; By obtaining the number of flicker times of the lighting device and comparing it with the preset flicker times threshold, if the number of flicker times of the lighting device is greater than the preset flicker times threshold, a flicker abnormality signal is generated, and the number of flicker times is retrieved according to the generated flicker abnormality signal, and the number of flicker times is substituted into the corresponding preset value range, and different value ranges are set to correspond to a performance control parameter respectively, 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; It should be noted that harmonics refer to the integer multiple frequency components in the signal except 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. Stroboscopic refers to the periodic change in the brightness of lighting equipment, which manifests as flickering or unstable brightness output. The stroboscopic phenomenon may have an adverse effect on the audience's visual perception, causing eye fatigue or discomfort. In stage performances, stroboscopic will destroy the stability of the lighting, affect the presentation of stage effects, and reduce the artistic effect. In addition, stroboscopic may also interfere with other electronic equipment on the stage, affecting their normal operation, thereby destroying the overall coordination and fluency of the performance; And execute step 6 after completing the wave reduction processing and the flash reduction processing.

[0022] Step 6: Verify and analyze the control effect of stage lighting. The specific analysis process is as follows: 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 display effect of the stage lights in the monitoring area. , specifically, according to the set model: ,in, and They represent the number of abnormal display times, 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, respectively, and and They are all natural numbers greater than 0. The normalization factor is used to represent the coefficient that converts each data in the calculation model into a dimensionless form; 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 the control display effect evaluation value of the stage lights in each monitoring area obtained 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; 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 through the display terminal; If the output result of adjusting the display effect level is adjusting the abnormal display effect level, a lighting equipment detection adjustment instruction is generated; When the display effect level of the stage lights in the monitoring area is at the normal display effect level, 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; 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 through the display terminal; 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.
