They are widely used in museums, science and technology museums, theme venues, corporate exhibition halls and other exhibition and display fields; At present, each lighting fixture installed in the multimedia exhibition hall is illuminated according to the pre-set parameters. It is difficult to reasonably analyze the lighting effect of each lighting fixture and accurately evaluate the lighting atmosphere creation performance of each area in the multimedia exhibition hall. It is also impossible to conduct a comprehensive analysis of the difficulty of lighting control in the multimedia exhibition hall and timely warn, which is not conducive to ensuring the display effect of the multimedia exhibition hall and increases the difficulty of supervision by backstage supervisors. In view of the above technical defects, a solution is now proposed. Summary of the invention

[0004] To achieve the above object, the present invention provides the following technical solutions: Intelligent lighting control system suitable for multimedia exhibition halls, including lighting monitoring and analysis module, intelligent lighting control module, regional importance decision module, regional atmosphere creation evaluation module and exhibition hall lighting supervision terminal; The lighting monitoring and analysis module monitors all the lighting in the multimedia exhibition hall, and determines whether the corresponding lighting is in an abnormal lighting effect state through analysis. When it is determined that the corresponding lighting is in an abnormal lighting effect state, the intelligent lighting control module regulates the corresponding lighting; The regional importance decision module divides the multimedia exhibition hall into several lighting areas, marks the corresponding lighting area as i, and i is a natural number greater than 1; obtains the regional grade coefficient of lighting area i through analysis, and sends the regional grade coefficient of lighting area i to the regional atmosphere creation evaluation module; The regional atmosphere creation evaluation module analyzes the regional lighting atmosphere creation performance of lighting area i, generates an atmosphere creation qualification signal or an atmosphere creation warning signal of lighting area i through analysis, and sends the atmosphere creation qualification signal or atmosphere creation warning signal of lighting area i to the exhibition hall lighting supervision end.

If the lighting effect coefficient exceeds the preset lighting effect coefficient threshold, it is determined that the corresponding lighting lamp is in an abnormal lighting effect state.

[0006] Furthermore, the specific analysis process of the regional importance decision module includes: Taking the current date as the end date and tracing back, a decision period of Y1 is set accordingly, the flow of people in lighting area i on the corresponding date in the decision period is calculated by ratio to the area of ​​lighting area i to obtain the distribution density coefficient, the distribution density coefficient of all dates in the decision period is averaged to obtain the distribution performance value, and the distribution density coefficient with the largest value in the decision period is marked as the distribution amplitude measurement value; And compare the distribution density coefficient with the preset distribution density coefficient threshold. If the distribution density coefficient exceeds the preset distribution density coefficient threshold, mark the corresponding date as the aggregation day of lighting area i; obtain the number of aggregation days corresponding to lighting area i during the decision period and calculate its ratio with Y1 to the aggregation analysis value; obtain the area grade coefficient of lighting area i by numerically calculating the distribution performance value, distribution amplitude measurement value and aggregation analysis value.

[0007] Furthermore, the specific operation process of the regional atmosphere creation evaluation module includes: When it is determined that the corresponding lighting lamp is in a lighting effect abnormal state, the determination moment of the lighting effect abnormal state is collected and marked as a first moment, and the moment when the intelligent lighting control module completes the regulation of the corresponding lighting lamp is collected and marked as a second moment, and the interval between the first moment and the second moment is marked as the lighting effect abnormality duration; Set a detection period, collect all the illumination time differences of the corresponding lighting lamps within the detection period, sum up all the illumination time differences of the corresponding lighting lamps to obtain the total illumination time difference value, and average the total illumination time differences of all lighting lamps in the lighting area i within the detection period to obtain the illumination time difference analysis value; And set a number of detection points in the detection period, and mark the corresponding detection time points as abnormal time points or excellent time points of lighting area i through analysis, and calculate the ratio of the number of abnormal time points corresponding to lighting area i in the detection period to the total number of detection time points to obtain the abnormal point ratio; and obtain the regional atmosphere creation coefficient by numerically calculating the abnormal time analysis value and the abnormal point ratio; The atmosphere creation matching threshold of lighting area i is obtained through analysis, and the regional atmosphere creation coefficient is numerically compared with the corresponding atmosphere creation matching threshold. If the regional atmosphere creation coefficient exceeds the corresponding atmosphere creation matching threshold, an atmosphere creation warning signal for lighting area i is generated; if the regional atmosphere creation coefficient does not exceed the corresponding atmosphere creation matching threshold, an atmosphere creation qualified signal for lighting area i is generated.

[0008] Furthermore, the specific analysis process of marking the corresponding detection time point as an abnormal table time point or an excellent table time point through analysis is as follows: The proportion of the number of lighting lamps in the lighting effect abnormality state in the lighting area i at the corresponding detection time point is collected and marked as the proportion of lighting lamps with abnormality, and the lighting effect coefficients of all lighting lamps in the lighting area i at the corresponding detection time point are averaged to obtain the lighting effect value, and the lighting effect coefficient with the largest value in the lighting area i at the corresponding detection time point is marked as the lighting abnormality amplitude value; The regional lighting evaluation value is obtained by numerically calculating the value of the proportion of abnormal lamps, the lighting efficiency value and the lighting difference value, and the regional lighting evaluation value is numerically compared with the preset regional lighting evaluation threshold. If the regional lighting evaluation value exceeds the preset regional lighting evaluation threshold, the corresponding detection time point is marked as the abnormal time point of lighting area i; if the regional lighting evaluation value does not exceed the preset regional lighting evaluation threshold, the corresponding detection time point is marked as the excellent time point of lighting area i.

[0009] Furthermore, the specific analysis process of obtaining the atmosphere creation matching threshold of the lighting area i through analysis is as follows: The area level coefficient of lighting area i is obtained, and several groups of preset area level coefficient ranges are set in advance, and each group of preset area level coefficient ranges corresponds to a group of preset area atmosphere creation coefficient thresholds. The area level coefficient of lighting area i is compared with all the preset area level coefficient ranges one by one, and the preset area level coefficient range containing the corresponding area level coefficient is marked as a matching range, and the preset area atmosphere creation coefficient threshold corresponding to the matching range is marked as the atmosphere creation matching threshold of lighting area i.

[0010] Furthermore, the exhibition hall lighting supervision end is communicated with the lighting management decision module, which is used to set a monitoring period, analyze the difficulty of lighting management for the multimedia exhibition hall during the monitoring period, generate a strong exhibition hall lighting management signal or a weak exhibition hall lighting management signal through analysis, and send the strong exhibition hall lighting management signal or the weak exhibition hall lighting management signal to the exhibition hall lighting supervision end.

[0011] Furthermore, the specific analysis process of the lighting management decision module includes: The total number of times that the atmosphere creation warning signal is generated in the lighting area i during the monitoring period is obtained and marked as the atmosphere creation warning frequency value, the atmosphere creation warning frequency values ​​of all lighting areas in the multimedia exhibition hall are averaged to obtain the exhibition hall atmosphere decision value, and the exhibition hall atmosphere decision value is numerically compared with the preset exhibition hall atmosphere decision threshold. If the exhibition hall atmosphere decision value exceeds the preset exhibition hall atmosphere decision threshold, a strong exhibition hall lighting management signal is generated.

[0012] Furthermore, if the exhibition hall atmosphere decision value exceeds the preset exhibition hall atmosphere decision threshold, the interval between the production date of the corresponding lighting lamp and the current date is marked as the lamp production interval value, and the lamp production interval value is numerically compared with the preset lamp production interval threshold. If the lamp production interval value exceeds the preset lamp production interval threshold, the corresponding lighting lamp is marked as a non-optimal lamp; If the lamp generation time interval value does not exceed the preset lamp generation time interval threshold, the real-time temperature and real-time vibration amplitude of the corresponding lighting lamp are collected, and the real-time temperature and real-time vibration amplitude are numerically compared with the preset real-time temperature threshold and the preset real-time vibration amplitude threshold respectively. If the real-time temperature or the real-time vibration amplitude exceeds the corresponding preset threshold, it is determined that the corresponding lighting lamp is in a lighting danger state; The total duration of the corresponding lighting lamp in the lighting danger state during the monitoring period is obtained and marked as the total lighting danger time value, and the number of occurrences of the single continuous duration of the corresponding lighting lamp in the lighting danger state during the monitoring period exceeding the corresponding preset single continuous duration threshold is marked as the lighting danger abnormal frequency value; the total lighting danger time value and the lighting danger abnormal frequency value are numerically compared with the preset lighting danger total time threshold and the preset lighting danger abnormal frequency threshold, respectively; if the total lighting danger time value or the lighting danger abnormal frequency value exceeds the corresponding preset threshold, the corresponding lighting lamp is marked as a non-optimal lamp; The proportion of non-optimal lights in the multimedia exhibition hall is obtained and marked as the non-optimal light detection value, the exhibition hall atmosphere decision value and the non-optimal light detection value are numerically calculated to obtain the exhibition hall management decision value, and the exhibition hall management decision value is numerically compared with the preset exhibition hall management decision threshold. If the exhibition hall management decision value exceeds the preset exhibition hall management decision threshold, a strong exhibition hall lighting management signal is generated; if the exhibition hall management decision value does not exceed the preset exhibition hall management decision threshold, a weak exhibition hall lighting management signal is generated.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0016] Embodiment 1: Figure 1 As shown, the intelligent lighting control system suitable for a multimedia exhibition hall proposed in the present invention includes a lighting monitoring and analysis module, an intelligent lighting control module, a regional importance decision module, a regional atmosphere creation evaluation module and an exhibition hall lighting supervision terminal; The lighting monitoring and analysis module monitors all the lighting in the multimedia exhibition hall, and determines whether the corresponding lighting is in an abnormal lighting effect state through analysis. When the corresponding lighting is determined to be in an abnormal lighting effect state, the corresponding lighting is regulated by the intelligent lighting control module. The lighting in the multimedia exhibition hall can be effectively monitored and regulated to ensure its lighting effect. It has a high degree of automation and is conducive to maintaining the lighting atmosphere required by the multimedia exhibition hall. The specific analysis process of the lighting monitoring and analysis module is as follows: The lighting brightness and lighting color temperature of the corresponding lighting lamp are collected, and the deviation value of the lighting brightness compared to the set standard brightness value is marked as the lighting detection coefficient, and the deviation value of the lighting color temperature compared to the set standard color temperature value is marked as the color temperature detection coefficient; The lighting effect coefficient XF is obtained by numerically calculating the lighting detection coefficient XS and the color temperature detection coefficient XW through the formula XF=(sw1*XS+sw2*XW) / 2; wherein sw1 and sw2 are preset weight coefficients with values ​​greater than zero, and the larger the value of the lighting effect coefficient XF is, the less the current lighting performance of the corresponding lighting lamp meets the requirements; The lighting effect coefficient XF is numerically compared with the preset lighting effect coefficient threshold. If the lighting effect coefficient XF exceeds the preset lighting effect coefficient threshold, it indicates that the current lighting effect of the corresponding lighting lamp is poor and the lighting performance does not meet the corresponding requirements, then the corresponding lighting lamp is judged to be in an abnormal lighting effect state.

[0017] The regional importance decision module divides the multimedia exhibition hall into several lighting areas, marks the corresponding lighting area as i, and i is a natural number greater than 1; the regional level coefficient QWi of lighting area i is obtained through analysis, and the regional level coefficient QWi of lighting area i is sent to the regional atmosphere creation evaluation module, which can not only reasonably evaluate the regional importance based on the flow of people in each area, but also provide data support for the analysis process of the regional atmosphere creation evaluation module to ensure the accuracy of its analysis results; the specific analysis process of the regional importance decision module is as follows: Taking the current date as the end date and tracing back, a decision period of Y1 is set accordingly, preferably, Y1 is fifteen days; the flow of people in lighting area i on the corresponding date in the decision period is calculated by ratio to the area of ​​lighting area i to obtain the distribution density coefficient, the distribution density coefficient of all dates in the decision period is averaged to obtain the distribution performance value, and the distribution density coefficient with the largest value in the decision period is marked as the distribution amplitude measurement value; And compare the distribution density coefficient with the preset distribution density coefficient threshold. If the distribution density coefficient exceeds the preset distribution density coefficient threshold, it indicates that the flow of people in the lighting area i on the corresponding date is large, and the corresponding date is marked as the gathering day of the lighting area i. The number of gathering days corresponding to the lighting area i in the decision period is obtained and the ratio is calculated with Y1 to obtain the gathering analysis value; The distribution performance value QSi, distribution amplitude measurement value QFi and aggregation analysis value QYi are numerically calculated through the formula QWi=(hy1*QSi+hy2*QFi) / 2+hy3* to obtain the regional grade coefficient QWi of lighting area i; wherein hy1, hy2 and hy3 are preset proportional coefficients whose values ​​are greater than zero, and the larger the value of the regional grade coefficient QWi is, the higher the importance of lighting area i is, and the more it is necessary to ensure the lighting atmosphere creation effect of lighting area i.

[0018] The regional atmosphere creation evaluation module analyzes the regional lighting atmosphere creation performance of lighting area i, generates an atmosphere creation qualified signal or an atmosphere creation early warning signal of lighting area i through analysis, and sends the atmosphere creation qualified signal or atmosphere creation early warning signal of lighting area i to the exhibition hall lighting supervision end; When the lighting supervision end receives the atmosphere creation warning signal, it will issue a corresponding warning, which can reasonably analyze and accurately judge the lighting atmosphere creation performance of each area in the multimedia exhibition hall, and promptly remind the back-end supervisors to conduct cause investigation and analysis and make corresponding improvement measures to ensure the lighting atmosphere creation effect of each area in the multimedia exhibition hall, and significantly reduce the supervision difficulty of the back-end supervisors; the specific operation process of the regional atmosphere creation evaluation module is as follows: When it is determined that the corresponding lighting lamp is in a lighting effect abnormal state, the determination moment of the lighting effect abnormal state is collected and marked as a first moment, and the moment when the intelligent lighting control module completes the regulation of the corresponding lighting lamp is collected and marked as a second moment, and the interval between the first moment and the second moment is marked as the lighting effect abnormality duration; Set a detection period, collect all the illumination time differences of the corresponding lighting lamps within the detection period, sum up all the illumination time differences of the corresponding lighting lamps to obtain the total illumination time difference value, and average the total illumination time differences of all lighting lamps in the lighting area i within the detection period to obtain the illumination time difference analysis value; And set a number of detection points within the detection period, collect the proportion of the number of lighting lamps in the lighting area i at the corresponding detection time point that are in the lighting effect abnormality state and mark it as the proportion of lighting lamps with abnormality, and calculate the average value of the lighting effect coefficients of all lighting lamps in the lighting area i at the corresponding detection time point to obtain the lighting effect value, and mark the lighting effect coefficient with the largest value in the lighting area i at the corresponding detection time point as the lighting abnormality amplitude value; The regional lighting evaluation value LXi is obtained by numerically calculating the ratio of the effective lamp LSi, the lighting effect value LFi and the lighting amplitude LPi through the formula LXi=wq1*LSi+(wq2*LFi+wq3*LPi) / 2; wherein wq1, wq2 and wq3 are preset proportional coefficients, wq1>wq2>wq3>0; and the larger the value of the regional lighting evaluation value LXi, the worse the overall performance of the regional lighting coordination of the lighting area i at the corresponding detection time point is; Compare the regional lighting review value with the preset regional lighting review threshold. If the regional lighting review value exceeds the preset regional lighting review threshold, it indicates that the regional lighting coordination performance of the lighting area i at the corresponding detection time point is generally poor, and the corresponding detection time point is marked as the abnormal performance time point of the lighting area i; if the regional lighting review value does not exceed the preset regional lighting review threshold, it indicates that the regional lighting coordination performance of the lighting area i at the corresponding detection time point is generally good, and the corresponding detection time point is marked as the excellent performance time point of the lighting area i, and the number of abnormal performance time points corresponding to the lighting area i in the detection period is calculated by ratio to the total number of detection time points to obtain the abnormal lighting point ratio; By formula The illumination difference time analysis value RXi and the illumination difference point occupation value TXi are numerically calculated to obtain the regional atmosphere creation coefficient YMi; wherein up1 and up2 are preset proportional coefficients, up2>up1>0; and the larger the value of the regional atmosphere creation coefficient YMi, the worse the regional lighting atmosphere creation performance of the lighting area i in the detection period is overall; The regional level coefficient of the lighting area i is obtained, and several groups of preset regional level coefficient ranges are set in advance, and each group of preset regional level coefficient ranges corresponds to a group of preset regional atmosphere creation coefficient thresholds. It should be noted that the larger the value of the preset regional level coefficient range, the smaller the value of the preset regional atmosphere creation coefficient threshold that matches it; Compare the regional level coefficient of lighting area i with all preset regional level coefficient ranges one by one, mark the preset regional level coefficient range containing the corresponding regional level coefficient as the matching range, and mark the preset regional atmosphere creation coefficient threshold corresponding to the matching range as the atmosphere creation matching threshold of lighting area i; The regional atmosphere creation coefficient YMi is numerically compared with the corresponding atmosphere creation matching threshold. If the regional atmosphere creation coefficient YMi exceeds the corresponding atmosphere creation matching threshold, it indicates that the regional lighting atmosphere creation performance of lighting area i during the detection period is generally poor, and an atmosphere creation warning signal for lighting area i is generated; if the regional atmosphere creation coefficient YMi does not exceed the corresponding atmosphere creation matching threshold, it indicates that the regional lighting atmosphere creation performance of lighting area i during the detection period is generally good, and an atmosphere creation qualified signal for lighting area i is generated.

[0019] Embodiment 2: Figure 2 As shown, the difference between this embodiment and the first embodiment is that the exhibition hall lighting supervision end is connected to the lighting management decision module in communication, and the lighting management decision module is used to set the monitoring period, preferably, the monitoring period is thirty days; the difficulty of lighting management for the multimedia exhibition hall during the monitoring period is analyzed, and the strong management signal of the exhibition hall lighting or the weak management signal of the exhibition hall lighting is generated through the analysis, and the strong management signal of the exhibition hall lighting or the weak management signal of the exhibition hall lighting is sent to the exhibition hall lighting supervision end; When the exhibition hall lighting supervision terminal receives the strong management signal of the exhibition hall lighting, it issues a corresponding warning to remind the back-end supervisors to adjust and optimize the exhibition hall lighting plan in time, strengthen the subsequent lighting control of the multimedia exhibition hall, ensure the lighting effect of the multimedia exhibition hall, and further reduce the supervision difficulty of the back-end supervisors for the multimedia exhibition hall; the specific analysis process of the lighting management decision module is as follows: The total number of times that the atmosphere creation warning signal is generated in the lighting area i during the monitoring period is obtained and marked as the atmosphere creation warning frequency value, the atmosphere creation warning frequency values ​​of all lighting areas in the multimedia exhibition hall are averaged to obtain the exhibition hall atmosphere decision value, and the exhibition hall atmosphere decision value is numerically compared with the preset exhibition hall atmosphere decision threshold. If the exhibition hall atmosphere decision value exceeds the preset exhibition hall atmosphere decision threshold, it indicates that the lighting control performance of the multimedia exhibition hall during the monitoring period is generally poor, and a strong exhibition hall lighting management signal is generated.

[0020] Furthermore, if the exhibition hall atmosphere decision value exceeds the preset exhibition hall atmosphere decision threshold, the interval between the production date of the corresponding lighting lamp and the current date is marked as the lamp production interval value, and the lamp production interval value is numerically compared with the preset lamp production interval threshold. If the lamp production interval value exceeds the preset lamp production interval threshold, indicating that the service life of the corresponding lighting lamp is approaching the end, the corresponding lighting lamp is marked as a non-optimal lamp; If the lamp generation time interval value does not exceed the preset lamp generation time interval threshold, the real-time temperature and real-time vibration amplitude of the corresponding lighting lamp are collected, and the real-time temperature and real-time vibration amplitude are numerically compared with the preset real-time temperature threshold and the preset real-time vibration amplitude threshold respectively. If the real-time temperature or the real-time vibration amplitude exceeds the corresponding preset threshold, it indicates that the real-time safety status of the corresponding lighting lamp is poor and is easily damaged, and the corresponding lighting lamp is judged to be in a lighting danger state; The total duration of the corresponding lighting lamp in the lighting danger state during the monitoring period is obtained and marked as the total lighting danger time value, and the number of occurrences of the single continuous duration of the corresponding lighting lamp in the lighting danger state during the monitoring period exceeding the corresponding preset single continuous duration threshold is marked as the lighting danger abnormal frequency value; the total lighting danger time value and the lighting danger abnormal frequency value are numerically compared with the preset lighting danger total time threshold and the preset lighting danger abnormal frequency threshold, respectively. If the total lighting danger time value or the lighting danger abnormal frequency value exceeds the corresponding preset threshold, it indicates that the operation risk of the corresponding lighting lamp during the monitoring period is relatively large, and the corresponding lighting lamp is marked as a non-optimal lamp; The proportion of non-optimal lamps in the multimedia exhibition hall is obtained and marked as the non-optimal lamp detection value. The exhibition hall atmosphere decision value HP and the non-optimal lamp detection value HF are numerically calculated by the formula NX=eq1*HP+eq2*HF to obtain the exhibition hall management decision value NX; wherein eq1 and eq2 are preset proportional coefficients, eq2>eq1>0.135; and the larger the value of the exhibition hall management decision value NX is, the greater the overall difficulty of lighting management for the multimedia exhibition hall is. The exhibition hall management decision value NX is numerically compared with the preset exhibition hall management decision threshold. If the exhibition hall management decision value NX exceeds the preset exhibition hall management decision threshold, it indicates that the lighting management difficulty for the multimedia exhibition hall is generally large, and it is necessary to strengthen the subsequent exhibition hall lighting supervision in time, then a strong exhibition hall lighting management signal is generated; if the exhibition hall management decision value NX does not exceed the preset exhibition hall management decision threshold, it indicates that the lighting management difficulty for the multimedia exhibition hall is generally small, then a weak exhibition hall lighting management signal is generated.

[0021] The working principle of the present invention is as follows: when in use, all the lighting lamps in the multimedia exhibition hall are monitored and analyzed through the lighting lamp monitoring and analysis module, and when it is determined that the corresponding lighting lamp is in an abnormal lighting effect state, the corresponding lighting lamp is adjusted through the intelligent lighting control module, which is conducive to maintaining the lighting atmosphere required to be created in the multimedia exhibition hall, and the multimedia exhibition hall is divided into several lighting areas through the regional importance decision module, and the importance of each area is reasonably evaluated based on the flow of people in each area. The regional atmosphere creation evaluation module analyzes the lighting atmosphere creation performance of the corresponding area in combination with the importance of the corresponding area, and can reasonably analyze and accurately judge the lighting atmosphere creation performance of each area in the multimedia exhibition hall, and promptly remind the backstage supervisor to conduct cause investigation and analysis and make corresponding improvement measures, so as to ensure the lighting atmosphere creation effect of each area in the multimedia exhibition hall and significantly reduce the supervision difficulty of the backstage supervisor.
