[0002] With the growth of people's spiritual and cultural needs, the forms of stage performances are becoming increasingly rich. Large-scale performances such as landscape shows, music festivals, concerts, and immersive interactive experiences emerge in an endless stream. The scale of performances is constantly expanding, and the level of safety risks is also increasing. The existing means for ensuring performance safety mainly rely on stage supervisors' inspections or the monitoring of video and sensor status to detect faults, but this method has limitations. In the face of emergencies, emergency response measures can only mitigate the impact of accidents and cannot prevent accidents from occurring. Some relevant parties in performances have weak safety awareness, overly pursue performance effects, ignore potential risks, have insufficient analysis of performance links and ineffective preventive measures, resulting in frequent stage safety accidents, seriously threatening the lives and safety of the masses. Once an accident occurs, it will cause a series of adverse consequences such as casualties, economic losses, and performance interruptions. Therefore, there is an urgent need for a health diagnosis method that can give early warnings, detect potential risks, and reduce the probability of performance failures to ensure the safety of stage performances. Summary of the Invention

By comprehensively analyzing the behavioral states of people and objects during stage performances, obtaining the consensus of evaluation true values, and based on the health diagnosis judgment criteria, the performance system is evaluated in advance, potential safety hazards are discovered and processed in a timely manner, the incidence of unsafe accidents is reduced, the smooth progress of performances is ensured, and at the same time, a technical foundation is laid for the development of intelligent theaters, so as to solve the foregoing problems existing in the prior art.

[0004] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] Refer to Figure 1 、 Figure 2 and Figure 3 A health diagnosis method based on a stage control system shown, including the following steps:

[0032] S100. Collect performance device information, including device life cycle, replacement frequency, failure frequency, usage frequency, usage duration, installation environment, divide weights for each key influencing factor according to common basic knowledge of the stage, and calculate the comprehensive analysis value of device information health diagnosis.

[0033] First, use comprehensive data information data sets such as databases and logs to obtain various information of the devices involved in the performance, such as Figure 2 shown, including device life cycle L C 、device replacement frequency R E 、device failure frequency F A 、device usage frequency U S 、device usage duration T S 、device installation environment I E etc. for statistics. If there are other influencing factors O T(Equipment maintenance records, etc.), can also be added according to the actual situation on site. Life cycle refers to the manufacturer's marking of how long the equipment can be used; replacement frequency refers to the time when the equipment cannot be used due to malfunction or failure during use, and thus replacement is required; equipment use frequency refers to the number of times the equipment is used during a performance; equipment usage time refers to the time the equipment is used from the beginning to the end of the performance; equipment installation environment refers to whether the equipment is in an ordinary environment, in an extremely cold or hot place, or in a polluted and dusty place. The key influencing factors mentioned above are weighted according to the commonly used basic knowledge of the stage. If the usage time has a greater impact, a higher weight can be assigned. Conversely, other factors that do not have a high impact are assigned lower weights.

[0034] S200. Classify the collected performance equipment information into stage machinery, lighting, audio-visual, electronic and electrical, and components according to their nature, determine the weight factor constant coefficient according to the degree of impact of each type of equipment on safety, and calculate the comprehensive health diagnosis assessment value after the equipment nature classification.

[0035] In this embodiment, the collected information is then classified according to the device properties, such as Figure 3 As shown, stage machinery M A , Lighting I 、Audio-visual V A , Electronics, electrical and components E E Different weights are mapped to the magnitude of the safety impact based on the classified equipment attributes. For example, the failure of stage machinery generally causes accidents with serious consequences, so the machinery can be paired with a higher weight. Audio and video usually have a lower adverse impact on stage performances than mechanical equipment, so a lower weight ratio can be assigned to them.

[0036] S300: Perform health diagnosis on the control system and the control console, and calculate a comprehensive health diagnosis evaluation value of the control system and the control console based on the diagnosis information.

[0037] Then, we will conduct objective and subjective health diagnosis on the control system reference technology and control console involved. Objective influencing factors of control system such as software quality evaluation QUA lit , involving the number of control system software failures MIS tak , the number of software defects found BUG num , other factors of software system SOF oth Wait, is there a system for subjective influencing factors to be stable and easy to use STA? bil ; Objective influencing factors of the console, such as whether the console is used effectively SUB sis Subjective factors such as key sensitivity SEN sit wait.

[0038] S400. Based on steps S100, S200, and S300, obtain the comprehensive health diagnosis evaluation value of the object in the stage control system, and determine the criterion for judging the high or low of the diagnosis value by calculating multiple times and taking the average.

[0039] In this embodiment, according to the above steps S100 to S3600, the comprehensive health diagnosis of the object in the stage control system can be obtained as: OBJ mid = DEV inf + DEV att + DEV ctr ; In the formula, OBJ mid represents the sum of the object health diagnosis influencing factors. The lower its value, the lower the accident probability of the system; the higher its value, the higher the accident probability. The criterion for judging the high or low of the diagnosis value can be processed by the principle of calculating multiple times, recording multiple times, and then taking the average.

[0040] S500. Set up logical diagnosis conditions according to the comprehensive health diagnosis evaluation value of the object;

[0041] S600. Use existing technology to sense the working state of the equipment operator and determine the comprehensive health diagnosis evaluation value of the operator.

[0042] In this embodiment, after completing the above comprehensive diagnosis of the object, the health diagnosis status of the equipment operators of each subsystem in the performance link is evaluated. In the existing science and technology, a relatively effective health status diagnosis has been carried out on the working state of people. The system technology can sense whether the on-site staff is in a normal working state NOR mal or an abnormal working state ABN nor . For example, the normal working state includes the human-machine not being separated, being concentrated, and having a good physical state without sudden diseases; the abnormal working state such as the human-machine being separated, that is, the person cannot be monitored on the console, being distracted, and sudden physical discomfort such as cardiovascular and cerebrovascular diseases, fever, etc.

[0043] S700. Based on the diagnosis results of the object and the personnel, obtain the final health diagnosis value.

[0044] In this embodiment, finally, a comprehensive health diagnosis calculation is performed on the results of steps S500 and S600. The final health diagnosis can be expressed as: FIN god = RES obj && PEP ple When it is true, that is, FIN god = 1, the system diagnosis result is usually called a healthy system. Conversely, the diagnosis result indicates that the system is in an extremely unhealthy state. Here, `&&` (logical AND) is used to connect two conditions.

[0045] S800 decides whether the performance continues according to the final health diagnosis value. If the system is diagnosed as healthy, the performance can proceed normally; if the system is not healthy, the performance should be immediately aborted. After troubleshooting and resolving potential safety hazards, the system diagnosis should be restarted until the result shows a healthy state before the performance can resume.

[0046] In this embodiment, when the system diagnosis result is a healthy score status, the system can be used normally; conversely, when the system diagnosis result is in an unhealthy condition, the performance should be aborted in a timely manner. After troubleshooting and resolving potential safety hazards, the system diagnosis should be restarted until the diagnosis result shows a healthy state before the performance can continue.

[0047] Preferably, the comprehensive analysis value of equipment information health diagnosis

[0048]

[0049] Among them, TEM = 2 refers to the two influencing factors of failure and replacement; NUM represents the sum of the types of key influencing factors of each piece of equipment information obtained for the equipment itself; ω is the proportion coefficient of the new factor added, which can be assigned according to the actual situation of the system.

[0050] L C represents the equipment life cycle; R E represents the equipment replacement frequency; F A represents the equipment failure frequency; U S represents the equipment usage frequency; T S represents the equipment usage duration; I E represents the equipment installation environment; O T represents the equipment maintenance record; represents the number of times the failure occurs in the usage frequency, represents the probability of equipment failure in the remaining usage cycle; represents the probability occupied by the failure times and replacement times among all key factors; is the weight value of the environment's influence on the failure factor. Generally, the probability of accidents accounts for a relatively small proportion, O T is also an influence factor that can be added adaptively according to the actual situation on-site.

[0051] Preferably, the comprehensive evaluation value of health diagnosis DEV att after classifying the equipment properties is calculated by the formula: DEV att = σ * M A + β * L I + γ * V A + ε * E E ,

[0052] Among them, σ, β, γ, and ε represent the weight factor constant coefficients of the influence of the attribute categories of the equipment on the stage safety accidents. The magnitudes of their values can be obtained by means of common expert weight calculation methods, which are quite mature and will not be elaborated here. Moreover, the sum of the coefficients is: σ + β + γ + ε = 1.

[0053] Preferably, the comprehensive health diagnosis evaluation value DEV of the control system and the console body ctr is calculated as follows: Among them, μ represents the objective influence factor coefficient of the console. In the formula, MIS tak +BUG num represents the objective influence factor coefficient of the control software, which mainly depends on the number of faults and defects generated by the system.

[0054] Preferably, the comprehensive health diagnosis evaluation value OBJ of the object mid is calculated as follows:

[0055] OBJ mid = DEV inf +BEV att +DEV ctr .

[0056] Preferably, the logical diagnosis condition is:

[0057] If

[0058] Preferably, the comprehensive health diagnosis evaluation value of the operator

[0059] Preferably, the final health diagnosis value FIN god = RES obj &&PEP ple .

[0060] Example:

[0061] Suppose a large-scale concert is about to be held, and the health diagnosis method of the present invention is used for evaluation before the performance. First, collect information on various types of equipment on the stage. For example, the life cycle L of a certain stage lift C is 10 years, the used duration T S is 2 years, the replacement frequency R E is 1 time, the failure frequency F A is 3 times, the usage frequency U S is 50 times, and the installation environment I E is a general indoor environment (assuming the value of the general environment is 1, and if it is a special environment, it can be assigned a value according to the actual situation). Calculate the comprehensive health diagnosis analysis value DEV of the equipment information according to the formula inf , assuming that NUM = 5 is determined (including FA , U S , L C , T S , I E and other key influencing factors), ω is set to 0.1 (determined according to the actual situation of the system). Substituting these values into the formula gives DEV inf value.

[0062] Next, classify the equipment by nature. Assume that stage machinery equipment accounts for 40% of the total equipment value (i.e., σ = 0.4), lighting equipment accounts for 25% (β = 0.25), audio-visual equipment accounts for 20% (γ = 0.2), and electronic and electrical components equipment accounts for 15% (ε = 0.15). Calculate DEV att .

[0063] Then, diagnose the control system. If the number of software faults MIS tak in the control system is 2, and the number of software defects BUG num is 5,

[0064] The comprehensive score of other factors SOF oth of the software system is 8 points (out of 10), and the system stability STA bil score is 7 points (out of 10); the usability SUB sis score of the console body is 8 points (out of 10), and the key sensitivity SEN sit score is 9 points (out of 10). μ is set to 0.6 (determined according to actual experience). Calculate DEV ctr . After that, calculate the comprehensive evaluation value OBJ mid = DEV inf + DEV att + DEV ctr . Take the average of multiple calculations to determine the diagnostic value. Determine the value of RES obj according to the logical diagnostic conditions. At the same time, judge the working status of the operator through the monitoring equipment to determine the value of PEP ple .

[0065] Finally, calculate FIN god = RES obj && PEP ple . If FIN god = 1, the concert can proceed normally; if FIN god = 0, immediately abort the performance, check and solve the safety hazards, and then re-diagnose.

[0066] The beneficial effects of the present invention are as follows: The present invention discloses a health diagnosis method based on a stage control system, which includes the following steps: collecting performance equipment information, classifying the collected performance equipment information by nature into stage machinery, lighting, audio-visual, electronic and electrical components, and calculating the comprehensive health diagnosis evaluation value after equipment nature classification; conducting health diagnosis on the control system and the console body, and calculating the comprehensive health diagnosis evaluation value of the control system and the console body according to the diagnosis information; calculating the comprehensive health diagnosis evaluation value of the objects in the stage control system, and setting up logical diagnosis conditions according to the object health diagnosis evaluation value; using the existing technology to perceive the working state of equipment operators and determining the comprehensive health diagnosis evaluation value of the operator; obtaining the final health diagnosis value according to the diagnosis results of the objects and personnel; and deciding whether the performance continues according to the final health diagnosis value.
