Description

Technical Field

[0001] This application relates to the technical field of stage lighting fixtures, and particularly to a hierarchical management system for stage lighting fixtures. Background Art

[0002] With the continuous development of stage lighting technology, the types and functions of stage lighting fixtures have become more and more diverse, and the management and control of stage lighting fixtures have become more and more complex. The precise controllability of stage lighting effects has a significant impact on the effect of stage performances. Therefore, a complete management system is needed to achieve efficient management and precise control of various stage lighting fixtures.

[0003] In the prior art, some automated management systems for stage lighting fixtures based on computer networks have emerged. These systems usually consist of a central server, multiple networked stage lighting fixture devices, and a management terminal. The server is used to store the status information and management information of the lighting fixtures. The lighting fixture devices upload their own status to the server, and the administrator views the lighting fixture status and issues control instructions through the management terminal. This centralized management is beneficial to improving management efficiency.

[0004] However, in the existing stage lighting fixture management system, when all users use the management terminal, they can view and operate all the information and control options of all stage lighting fixtures, which poses a relatively large security risk. This situation needs to be further improved. Summary of the Invention

[0005] In order to solve the problem that there is a relatively large security risk when users of the existing stage lighting fixture management system use the management terminal, this application provides a hierarchical management system for stage lighting fixtures, adopting the following technical solutions:

[0006] A hierarchical management system for stage lighting fixtures, comprising:

[0007] A server, used for storing the status information and management information of stage lighting fixtures;

[0008] Multiple stage lighting fixtures, each stage lighting fixture is connected to the server and used for sending its own status information to the server; a management terminal, used for connecting to the server and displaying corresponding stage lighting fixture status information, management information, and management interface according to user permissions;

[0009] Wherein, the management terminal is divided into multiple levels according to the user permissions, and the status information, management information, and management interfaces of the stage lighting fixtures that can be viewed and operated by users at different levels are different.

[0010] By adopting the above technical solution, in this application, the management terminal is divided into multiple levels according to user permissions, so that users at different levels can view and operate different stage lighting fixture status information, management information, and management interfaces, thus realizing a reasonable classification of lighting fixture information and control permissions; high-level users can view and control more content, while low-level users can only see and operate a limited part, effectively avoiding potential safety hazards caused by excessive permissions; at the same time, this design is also conducive to improving the manageability of the system, enabling managers at different levels and with different responsibilities to obtain personalized interfaces and permission allocations that match their work when using the system, improving the efficiency and convenience of lighting fixture management.

[0011] Optionally, the status information of the stage lighting fixture includes the light display color, the heating condition, and the installation position information.

[0012] Optionally, the management interface includes a fault warning interface, which is used to send fault warning information to the manager when the server detects a fault in the stage lighting fixture. The fault warning information includes the number of the stage lighting fixture where the fault occurs, the fault type, and the fault occurrence time.

[0013] By adopting the above technical solution, in this application, the lighting fixture fault information is promptly pushed to the manager through the fault warning interface, which can significantly improve the efficiency of fault discovery and handling; the manager no longer needs to conduct regular manual inspections, and can real-time know which lighting fixtures have what kind of faults, so as to be able to quickly determine the cause of the fault and take corresponding troubleshooting and repair measures, maximizing the avoidance of performance accidents caused by faults; at the same time, data such as the detailed fault type and occurrence time in the warning information provide strong support for the manager's fault diagnosis, helping to shorten the time for fault analysis and handling, and improving the convenience of fault response and repair.

[0014] Optionally, the server is further configured to:

[0015] Real-time monitor and analyze the status information uploaded by the target stage lighting fixture, where the target stage lighting fixture is any one of the multiple stage lighting fixtures;

[0016] Conduct fault prediction analysis on the status information and display the prediction analysis result;

[0017] Extract the status information for statistical management, generate a management log and display it;

[0018] Accept a control request input by the user through the management terminal and publish the control request to the target stage lighting fixture.

[0019] By adopting the above technical solution, through the real-time monitoring and big data analysis of the server, the present application can comprehensively control the operating status of stage lights, discover anomalies in advance and predict potential faults, so that corresponding measures can be taken in advance to avoid the occurrence of faults or minimize the impact of faults; meanwhile, statistical management and log generation are also helpful for tracing and analyzing historical data and summarizing experience and lessons; in addition, centralized reception and issuance of control requests can ensure the consistency and orderliness of instructions, improve the reliability and security of control, and are beneficial to enhancing the precision and controllability of stage performances.

[0020] Optionally, the server analyzes the lighting display color in the status information, including the following steps: extracting the RGB values of the display color of the target stage light from the status information, and calculating the color temperature of the current lighting display according to the RGB values;

[0021] Inputting the color temperature into a preset prediction model to obtain the color temperature change trend in a future period of time;

[0022] Displaying the prediction result of the color temperature change trend in the fault prediction analysis result of the management interface.

[0023] By adopting the above technical solution, the present application monitors the color temperature of the stage light display in real time and predicts the future trend, so as to prejudge in advance whether the lighting system may have faults, such as color distortion caused by the aging of the light-emitting circuit, etc.; once it is predicted that the color temperature will change abnormally, the system will intelligently issue a warning, and the management personnel can intervene in advance, repair or replace relevant components to avoid major faults during the performance and affecting the audience's perception. At the same time, showing the color temperature change trend is also helpful for the management personnel to adjust the light parameters in time, optimize the lighting effect, and greatly improve the reliability and precision control ability of the entire lighting system.

[0024] Optionally, the server analyzes the heat generation situation in the status information, including the following steps: calculating the heat generation according to the working voltage, working current and working time in the status information;

[0025] Obtaining the model parameters of the target stage light from the server, and extracting the rated heat dissipation parameters in the model parameters; calculating the difference between the heat generation and the rated heat dissipation parameters, if the difference exceeds a preset threshold, it is judged that an overheat fault will occur, and the overheat fault judgment result is displayed in the fault prediction analysis result of the management interface.

[0026] By adopting the above technical solution, through the comparative analysis of the calorific value and the rated heat dissipation capacity, the present application can accurately predict whether the lamp will fail due to overheating. Managers can take timely measures, such as reducing the power, strengthening the heat dissipation, etc., to avoid the actual overheating damage of the lamp. At the same time, the prediction results are directly displayed on the management interface, enabling managers to clearly and intuitively understand the overheating risks of each lamp, so as to optimize the layout of the stage lights and adjust the power consumption mode in a targeted manner, comprehensively eliminate the overheating hidden dangers, and ensure the safe and reliable operation of the stage lighting system.

[0027] Optionally, the server analyzes the installation positions of the stage lights in the status information, including the following steps:

[0028] Obtain the three-dimensional space coordinate positions of all stage lights;

[0029] Input all the three-dimensional space coordinate positions into the K-means clustering algorithm, set the number of clusters K, and perform iterative operations to obtain K cluster centers;

[0030] According to the distances between each of the three-dimensional space coordinate positions and the K cluster centers, divide all stage lights into K cluster partitions;

[0031] Mark different cluster partitions on the management interface with different colors or marks, and display the number and installation positions of the stage lights in each cluster partition.

[0032] By adopting the above technical solution, the present application enables the server to perform clustering analysis on the three-dimensional installation positions in the stage light status information, divides all lights into K partitions according to the spatial coordinates using the K-means algorithm, and differentiates different partitions with different colors or marks on the management interface, displaying the number of lights and the specific installation positions inside each partition; enabling managers to more intuitively and efficiently master the layout of the entire stage lights, adopting targeted management and operation strategies for different regions, and optimizing the layout arrangement of the lights accordingly, thereby comprehensively improving the manageability, controllability and overall effect of the stage lighting system.

[0033] Optionally, after receiving the control request input by the user through the management terminal, the server performs the following steps:

[0034] Obtain the user position information, user permission level information corresponding to the management terminal, and the installation position information of the target stage light;

[0035] Obtain the fault prediction analysis result;

[0036] Based on the fault prediction and analysis results, the user location information, and the installation location information, and based on the user permission level information, calculate and adjust the temporary operation permission of the management terminal for the target stage lighting fixture;

[0037] Determine the stage area and lighting fixture group that can be controlled by the control request according to the adjusted temporary operation permission.

[0038] By adopting the above technical solution, the present application obtains the user location information, permission level, target lighting fixture location, and fault prediction and analysis results, then calculates and adjusts the temporary operation permission of the user for the target lighting fixture based on this information, and finally determines the stage area and lighting fixture group that the user can control according to the adjusted permission; it can dynamically adjust and optimize user permissions, achieve refined hierarchical and zonal management and control, thus ensuring the safe and reliable operation of the stage lighting system to the greatest extent, avoiding the fault risk caused by misoperation, and providing a reasonable and efficient mechanism for temporary permission adjustment in case of emergency, comprehensively improving the operation and maintenance management level of the entire system.

[0039] Optionally, calculating and adjusting the temporary operation permission of the management terminal for the target stage lighting fixture based on the fault prediction and analysis results, the user location information, and the installation location information, and based on the user permission level information, specifically includes the following steps:

[0040] Determine the current fault risk level of the target stage lighting fixture according to the fault prediction and analysis results;

[0041] Calculate the actual distance between the management terminal and the target stage lighting fixture according to the user location information and the installation location information;

[0042] Input the fault risk level and the actual distance into a preset risk strategy rule to determine the temporary permission adjustment value;

[0043] Combine the temporary permission adjustment value with the user permission level information to calculate the temporary operation permission of the management terminal for the target stage lighting fixture.

[0044] By adopting the above technical solution, the present application comprehensively considers the current fault risk level of the target lighting fixture and the actual distance between the management terminal and the target lighting fixture, and calculates these information according to the preset risk strategy rule to determine the degree of adjustment required for the temporary permission. Finally, the adjustment value is combined with the user's original permission level to dynamically calculate the temporary operation permission of the management terminal for the target lighting fixture, which can reasonably allocate control permissions according to the actual situation, maximize the convenience of on-site operation and emergency response ability on the premise of ensuring the safe and reliable operation of the system, and comprehensively improve the usability and reliability of the stage lighting control system.

[0045] Optionally, the preset risk strategy rule is as follows:

[0046] The risk coefficient f mapped according to the current fault risk level r , 0 ≤ f r ≤ 1;

[0047] According to the actual distance and the preset maximum effective adjustment distance, the distance coefficient f is obtained d , f d = d / d max , 0 ≤ f d ≤ 1, where d is the actual distance and d max is the preset maximum effective adjustment distance;

[0048] Calculate the temporary permission adjustment value Δp = (f r + λ * (1 - f d )) u ) * P u v , where P u is the user permission level, 0 ≤ P u ≤ 1, and λ, u, and v are respectively the influence weight of the distance factor, the influence degree of the distance factor on the adjustment value, and the influence degree of the user permission level on the adjustment value, u > 1, v > 1.

[0049] By adopting the above technical solution, although the on-site staff in this application has low original permissions, they can still obtain appropriate temporary operation permissions in case of emergency, so as to diagnose and maintain the faulty lamps in a timely and accurate manner, improving the efficiency and reliability of on-site work; at the same time, it balances the permission allocation requirements of on-site and remote users, distributes appropriate temporary permissions to on-site staff, and avoids remote users obtaining excessive improper permissions, maximizing the reliability and security of the system.

[0061] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of the present application, the singular forms "a", "an", "the", "above-mentioned", "said", and "this" are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used in the present application refers to any or all possible combinations including one or more of the listed items.

[0062] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and should not be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0063] The embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the specification.

[0064] The present application provides a hierarchical management system for stage lights. Referring to Figure 1 , it includes a server, a plurality of stage lights, and a management terminal. The server is used to store the status information and management information of the stage lights; each stage light among the plurality of stage lights is connected to the server and is used to send its own status information to the server; the management terminal is used to be connected to the server and display the corresponding stage light status information, management information, and management interface according to the user permissions; wherein, the management terminal is divided into multiple levels according to the user permissions, and the stage light status information, management information, and management interfaces that can be viewed and operated by users at different levels are different.

[0065] In this embodiment, the server is the core of the system, responsible for storing and processing the status information and management information of the stage lights and providing data support for the management terminal. The system includes a plurality of stage lights connected to the server, and each light can detect and report its own status information. The status information includes the light display color, the heat generation situation, and the three-dimensional installation position information. The management terminal is used to be connected to the server, receive and display the stage light status information, management information, and management interface provided by the server, and can view and control the light status according to the user permissions to achieve hierarchical management.

[0066] Specifically, the server is a computer host configured with corresponding software and hardware, installed with a database system and a processing module. The server is connected to each stage light through a wired or wireless network, regularly or in real-time receives the status data from the lights, and stores it in the database. The server can also run analysis algorithms to perform fault prediction, clustering analysis, etc. on the status data, and form management information for display on the management terminal. The stage lights can be intelligent LED lights with communication functions or other types of professional stage lights. The lights are built-in with a color temperature sensor, a temperature sensor, a power detection circuit, etc., for real-time acquisition of RGB display values, heat generation, and other operating status parameters. The lights are also integrated with a positioning module, which can determine its three-dimensional spatial coordinate position. These status data will be periodically uploaded to the server via wireless or wired means. The management terminal is a terminal device such as a computer, a tablet, or a smartphone installed with client software. After different levels of users log in, the management terminal will obtain corresponding status data, analysis information, and a personalized management interface from the server according to the user's permission level. For example, ordinary users can only view the simple status of some lights, while administrators can view the detailed data of all lights and the fault prediction results, and can enter newly installed stage lights, etc. The management terminal can also send control instructions to the server to control the working mode of specific areas or specific lights.

[0067] In one embodiment, the management interface further includes a fault alarm interface, which is used to send fault alarm information to the management personnel when the server detects that a stage light has a fault. The fault alarm information includes the number of the stage light with the fault, the type of the fault, and the time of the fault occurrence. The management personnel do not need to conduct regular manual inspections anymore, and can know in real-time which lights have what kind of faults, so as to be able to quickly determine the cause of the fault and take corresponding troubleshooting and repair measures, and maximize the avoidance of performance accidents caused by faults; at the same time, data such as the detailed fault type and occurrence time in the alarm information provide strong support for fault diagnosis for the management personnel, which helps to shorten the time for fault analysis and processing, and improves the convenience of fault response and repair.

[0068] In one embodiment, referring to Figure 2 , the server is further used for:

[0069] S210. Real-time monitor and analyze the status information uploaded by the target stage light.

[0070] Wherein, the target stage light is any one of multiple stage lights.

[0071] In this embodiment, the server remains connected to all stage lights, can receive and monitor in real-time the status data uploaded by any target light, and perform real-time analysis on these data.

[0072] Specifically, the server can be deployed with a data collection module to establish a communication channel with the lamps through a network protocol, continuously obtain the status data packets sent by each connected lamp, and parse the data packets to obtain status parameters. The server also integrates data analysis algorithms to perform real-time analysis on the real-time status data, such as fault risk grading, heat generation calculation, and usage duration statistics.

[0073] S220. Conduct fault prediction analysis on the status information and display the prediction analysis results.

[0074] In this embodiment, based on the historical status data of the lamps, the server runs a fault prediction analysis algorithm model to perform intelligent prediction analysis on the possible future fault risks of each lamp, and displays the analysis results in a friendly form.

[0075] Specifically, the server can set a fault prediction result display area in the management interface and display it in a prominent way with text, icons, or colors for easy viewing and processing by the management personnel.

[0076] S230. Extract the status information for statistical management, generate a management log and display it.

[0077] Specifically, the server is deployed with a data statistics module, sets and stores statistical rules in multiple dimensions, such as by time period, by fault type, by region, etc. It periodically extracts the required target data from the received massive status data for conditional filtering, sorting, counting and other statistical analyses, generates a management data file, presents it in the form of a log, or can also generate a report format and display it in the management interface of the server in the form of a list or chart for the management personnel to view and print.

[0078] S240. Receive the control request input by the user through the management terminal and publish the control request to the target stage lamp.

[0079] Specifically, referring to Figure 3 , in step S220, the server analyzes the light display color in the status information, including the following steps:

[0080] S310. Extract the RGB values of the target stage lamp display color from the status information and calculate the color temperature of the current light display according to the RGB values.

[0081] Specifically, the server first needs to extract the RGB component values of the display color from the status data uploaded by the lamp, and then based on these values, substitute them into the color temperature calculation formula to obtain the color temperature value that matches the human eye perception as an important reference for evaluating the light display quality.

[0082] S320. Input the color temperature into the preset prediction model to obtain the color temperature change trend in the future for a period of time.

[0083] In this embodiment, the system pre-trains a machine learning prediction model to perform intelligent prediction and analysis on the color temperature change of the lamp in a future period of time.

[0084] Specifically, the prediction model can adopt time series analysis with historical color temperature data as input to train a model capable of predicting the color temperature change trend. The server uses the real-time color temperature as the model input, and can obtain the change curve of the color temperature of the lamp in a future period of time, and judge whether an abnormal situation of gradual increase or decrease will occur.

[0085] S330. Display the prediction result of the color temperature change trend in the fault prediction analysis result of the management interface.

[0086] Refer to Figure 4 , in step S220, the server analyzes the heating situation in the status information, including the following steps:

[0087] S410. Calculate the calorific value according to the working voltage, working current and working time in the status information.

[0088] S420. Obtain the model parameters of the target stage lamp from the server, and extract the rated heat dissipation parameters in the model parameters.

[0089] In this embodiment, in order to judge whether the calorific value exceeds the safe range, the server obtains the rated maximum heat dissipation parameter of this type of lamp as the standard value for comparison.

[0090] Specifically, the server integrates a stage lamp model parameter database, which stores the technical specification data of different types of lamps. When it is necessary to evaluate a certain target lamp, the server can query the corresponding model parameter file from the database, and extract key heat dissipation parameters such as rated heat dissipation power and rated working temperature as standard thresholds.

[0091] S430. Calculate the difference between the calorific value and the rated heat dissipation parameter. If the difference exceeds the preset threshold, it is judged that an overheating fault will occur, and the overheating fault judgment result is displayed in the fault prediction analysis result of the management interface.

[0092] Refer to Figure 5 , in step S220, the server analyzes the installation position of the stage lamp in the status information, including the following steps:

[0093] S510. Obtain the three-dimensional space coordinate positions of all stage lamps.

[0094] S520. Input all the three-dimensional space coordinate positions into the clustering algorithm, set the number of clusters K, and perform iterative operations to obtain K clustering centers.

[0095] In this embodiment, the server takes all the obtained coordinate position data of the lamps as input, applies the K-means clustering algorithm to perform unsupervised clustering analysis on these coordinates, and automatically discovers K clustering center points inherent in the data.

[0096] Specifically, the expected number of clusters K is set in advance. The server can estimate a reasonable K value according to the actual layout of the stage, such as 8 partitions. The algorithm will randomly specify K initial clustering centers, and then iteratively calculate the distances between each coordinate point and the K centers, re-divide which cluster each coordinate belongs to, and recalculate the center point coordinates of each cluster until the clustering centers are stable.

[0097] S530. Divide all the stage lamps into K clustering partitions according to the distances between each three-dimensional space coordinate position and the K clustering centers.

[0098] Specifically, for the coordinate position of each lamp, the server calculates the Euclidean distance between this coordinate and the K clustering center points, and assigns this lamp to the clustering partition with the closest distance. In this way, all the lamps are calculated in turn, and finally all the lamps will be reasonably divided into K different clustering partitions, and the coordinate positions of the lamps in each partition are relatively concentrated.

[0099] S540. Mark different clustering partitions with different colors or marks on the management interface, and display the number of stage lamps and installation positions in each clustering partition.

[0100] Specifically, on the stage floor plan layout of the management interface, the server uses different colors or marks to label different clustering partitions, such as using a red mark for partition A and a blue mark for partition B, etc. The coordinate positions of all the stage lamps in each partition will be plotted as points within this partition. At the same time, beside each partition, the number statistics of how many stage lamps are in this partition, as well as the specific coordinate position range of this partition, are displayed, so that the regional distribution of the lamps can be presented at a glance.

[0101] In one embodiment, referring to Figure 6 , after receiving the control request input by the user through the management terminal in step S240, the server performs the following steps:

[0102] S610. Obtain the user position information, user permission level information corresponding to the management terminal, and the installation position information of the target stage lamp.

[0103] S620. Obtain the result of fault prediction analysis.

[0104] S630. Calculate and adjust the temporary operation permission of the management terminal for the target stage lighting fixture based on the fault prediction analysis result, user location information, installation location information, and user permission level information.

[0105] S640. Determine the stage area and lighting fixture group that can be controlled by the control request according to the adjusted temporary operation permission.

[0106] In one embodiment, referring to Figure 7 , in step S630, calculating and adjusting the temporary operation permission of the management terminal for the target stage lighting fixture based on the fault prediction analysis result, user location information, installation location information, and user permission level information specifically includes the following steps:

[0107] S710. Determine the current fault risk level of the target stage lighting fixture according to the fault prediction analysis result.

[0108] In this embodiment, the server evaluates the current fault risk level of the lighting fixture based on the previously obtained fault prediction analysis result of the target lighting fixture, which is an important reference for subsequent permission adjustment.

[0109] Specifically, the server sets multiple fault risk levels, such as low risk, medium risk, high risk, etc., and scores the risk levels based on the severity of different prediction indicators such as color shift and excessive heat generation to obtain the comprehensive risk level of the target lighting fixture. For example, if the heat generation of the lighting fixture exceeds 30% of the rated value and the color temperature change trend is large, it can be determined as a high risk level; if all parameters are within the normal range, it is a low risk level.

[0110] S720. Calculate the actual distance between the management terminal and the target stage lighting fixture according to the user location information and installation location information.

[0111] In this embodiment, the server respectively obtains the current location of the management terminal and the installation location information of the target lighting fixture, and calculates the actual distance between them based on these two locations. The closer the distance, the higher the convenience of the administrator's actual on-site operation.

[0112] S730. Input the fault risk level and the actual distance into the preset risk strategy rule to determine the temporary permission adjustment value.

[0113] Specifically, the preset risk strategy rule is: the risk coefficient f r , 0 ≤ f r ≤ 1. According to the actual distance and the preset maximum effective adjustment distance, obtain the distance coefficient f d , f d = d / d max , 0 ≤ f d≤ 1, where d is the actual distance, and d max is the preset maximum effective adjustment distance. Calculate the temporary permission adjustment value Δp = (f r + λ * (1 - f d ) u ) * P u v , where P u is the user permission level, 0 ≤ P u ≤ 1, and λ, u, and v are respectively the influence weight of the distance factor, the influence degree of the distance factor on the adjustment value, and the influence degree of the user permission level on the adjustment value. u > 1 and v > 1.

[0114] Through the preset risk strategy rules, since the temporary permission adjustment value increases as the actual distance decreases and increases as the current fault risk level increases, on-site staff can obtain appropriate temporary operation permissions despite their low original permissions in case of emergency, so as to diagnose and maintain faulty lamps in a timely and accurate manner, improving the efficiency and reliability of on-site work; it balances the permission allocation requirements of on-site and remote users, distributes appropriate temporary permissions to on-site staff, and at the same time prevents remote users from obtaining excessive improper permissions, maximizing the reliability and security of the system.

[0115] S740. Combine the temporary permission adjustment value with the user permission level information to calculate the temporary operation permission of the management terminal for the target stage lamp.

[0116] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0117] The above are all preferred embodiments of the present application. Without restricting the protection scope of the present application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
