[0027] In a preferred embodiment, it further includes a high-risk positioning module and a data analysis module;

[0028] A first pressure sensor is installed on the bottom surface of the stage deck.

[0035] If the number of pressure signals is greater than or equal to the maximum value of the number threshold, the corresponding stage deck will generate replacement information;

[0036] If the number of compressed signals is less than the maximum value of the quantity threshold and greater than the minimum value of the quantity threshold, position replacement information is generated; if the number of compressed signals is less than or equal to the minimum value of the quantity threshold, no information is generated.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0047] Example 1

[0048] See also Figure 1 As shown, the stage safety system based on the digital information network described in this embodiment includes a data acquisition module 10 , an operation information analysis module 20 , and a risk qualitative module 30 .

[0049] The operation information analysis module 20 is used to collect stage operation information and send the stage operation information to the operation information analysis module 20. The stage operation information includes stage low-level operation information and stage high-level operation information.

[0050] See also Figure 2 As shown, the low-stage operation information includes the column monitoring height error value, the stage platform temperature value, the stage current monitoring value, and the concentrated value of the distance between the four corners of the stage platform;

[0051] The above-mentioned column monitoring height error value obtaining step includes: first obtaining the column monitoring height value, the column monitoring height value is the distance value between the first distance sensor 3 and the ground measured by the first distance sensor 3 installed at a fixed height on the surface of the stage column 1, marking a plurality of stage columns 1 supporting a stage deck 2 as a group, and marking the sum of the height values ​​of all the first distance sensors 3 obtained from the ground in the group for the first time as Y k, the sum of the height values ​​of the first distance sensor 3 from the ground obtained at the same time is marked as Y k+1 ,Y k+1 With Y k The absolute value of the difference is the column monitoring height error value; if the column monitoring height error value is larger, it means that the stage column 1 is gradually sinking into the ground. When the sinking amplitude of the stage column 1 at a certain place is too large, the corresponding stage surface will also be concave.

[0052] The stage deck temperature value is the surface temperature value under each stage deck 2, which is obtained by a temperature sensor installed under the stage deck 2. Following the development of technology in recent years, the stage deck is not a traditional plate-shaped structure. In this embodiment, the stage deck 2 is a screen stage deck with a display function. After power is turned on, the patterns displayed by multiple stage decks 2 form a complete image; the stage current monitoring value is the stage leakage current, which can be obtained by monitoring the current of the steel structure supporting the stage deck by the leakage sensor.

[0053] The above-mentioned process of obtaining the concentrated value of the distance between the four corners of the stage deck includes: a second distance sensor 4 installed at a fixed height on the surface of the stage column 1 measures the distance between the second distance sensor 4 and the stage deck 2, including x i , i=1, 2, 3, 4...i, i is the number of distances between the second distance sensor 4 and the bottom corner of the stage deck 2. When first installed, the i second distance sensors 4 located below the stage deck 2 are at the same distance from the ground of the stage deck 2. According to the formula:

[0054]

[0055] Where px is the concentrated value of the distance between the four corners of the stage deck, m = {1, 2, 3, 4...m}, m represents the number of distance values ​​between the second distance sensor 4 and the bottom corners of the stage deck 2, x i Indicates the distance between the second distance sensor 4 and the stage deck 2, x p Represents the average value of the distance values ​​between all second distance sensors 4 and the stage platform 2; the above-mentioned first distance sensor 3 and second distance sensor 4 can be laser ranging sensors.

[0056] The smaller the concentrated value px of the distance between the four corners of the stage deck, the closer the distance between the four second distance sensors 4 and the four corners of the stage deck 2 is; the opposite is true, that is, there may be a loose connection between the stage deck 2 and the stage column 1. When stepping on the corresponding stage deck 2, one side of the stage deck 2 will tilt up. If the tilting amplitude is too large, it will also affect the performer's body balance, and the corresponding tilting will also make a sound. That is, the size of the concentrated value px of the distance between the four corners of the stage deck can be used to judge whether there is an abnormal sound when stepping on the stage deck 2. The specific judgment steps include:

[0057] The concentrated value px of the distance between the four corners of the stage platform is compared with the set px threshold. The px threshold technicians select the optimal numerical setting based on a large number of experimental settings. If the concentrated value px of the distance between the four corners of the stage platform is less than the px threshold, it means that the stage platform 2 is not tilted much, the corresponding sound is not loud, and when the performer steps on the stage platform 2, it will not have much impact on the performer's body balance; if the concentrated value px of the distance between the four corners of the stage platform is greater than or equal to the px threshold, it means that the stage platform 2 is tilted much, the corresponding sound is loud, and it is easy to affect the performer's body balance.

[0058] The operation information analysis module 20 receives the operation information at the lower part of the stage and the operation information at the upper part of the stage, and analyzes them respectively. The operation information at the lower part of the stage is analyzed to obtain an emergency risk signal, a low-level mild risk signal, a low-level moderate risk signal, and a low-level high risk signal; the operation information at the upper part of the stage is analyzed to obtain a high-level mild risk signal, a high-level moderate risk signal, and a high-level high risk signal; and the emergency risk signal, low-level mild risk signal, low-level moderate risk signal, low-level high risk signal, high-level mild risk signal, high-level moderate risk signal, and high-level high risk signal obtained by the analysis are sent to the risk qualitative module 30.

[0059] The operation information analysis module 20 analyzes the operation information of the lower part of the stage by dividing the stage into n areas, marking the n divided areas as monitoring objects, marking the number of monitoring objects as n, n = 1, 2, 3...n, n is an integer greater than 1, and the monitoring objects include the stage surface and the ceiling above the stage surface. The areas divided by the stage surface are associated with the ceiling areas directly above the areas divided by the stage surface; that is, if a stage deck 2 is divided into one area, the ceiling area directly above this stage deck 2 is associated with this stage deck 2;

[0060] The column monitoring height error value, stage platform temperature value, and stage platform four corner spacing concentration value are marked as: Gwz n 、Wdz n 、Joz n , according to the formula: DCF n =a1*Gwz n +a2*Wdz n +a3*Joz n , calculate the DCF risk factor at the bottom of the stage n ,a1, a2, and a3 are the preset weight coefficients of the column monitoring height error value, the stage platform temperature value, and the stage platform four corner spacing concentration value, a1>a2>a3>0, and a1+a2+a3=3.453.

[0061] It should be noted that the risk factor DCF at the bottom of the stage n The larger the performance value, the higher the risk of failure of the monitored object and the more likely it is to cause a safety accident; otherwise, the opposite is true.

[0062] Set the leakage current threshold and the low risk coefficient range threshold. If the stage current monitoring value is greater than or equal to the leakage current threshold, the monitored object will be marked as an emergency risk signal. If the stage current monitoring value is less than the leakage current threshold, the monitored object will not be marked.

[0063] If the risk factor DCF at the low point of the stage n If the DCF value is greater than or equal to the maximum value of the low-level risk coefficient range threshold, the monitored object is marked as a low-level high-risk signal; if the DCF value is greater than or equal to the maximum value of the low-level risk coefficient range threshold, the monitored object is marked as a low-level high-risk signal; n If the DCF value is less than the maximum value of the low risk coefficient range threshold and greater than the minimum value of the low risk coefficient range threshold, the monitored object is marked as a low moderate risk signal; if the DCF value is less than the maximum value of the low risk coefficient range threshold, the monitored object is marked as a low moderate risk signal; n If the value is less than or equal to the minimum value of the low risk coefficient range threshold, the monitored object is marked as a low mild risk signal.

[0064] The above-mentioned stage high-altitude operation information includes the stage support inclination value, the ceiling suspension vibration value, and the node bolt looseness value. The stage support inclination value is the inclination of the ceiling support above the stage, which is specifically obtained by monitoring the inclination sensor; the ceiling suspension is an object installed on the ceiling, including spotlights, speakers and other objects installed on the ceiling. The ceiling suspension vibration value is obtained by monitoring the vibration sensor on the installation surface of the suspension; the node bolt is the fixing bolt at the connection between the bracket and the ceiling. The node bolt looseness value is obtained by monitoring the elongation of the wireless bolt loosening sensor.

[0065] The operation information analysis module 20 analyzes the operation information at the stage height by marking the stage support tilt value, ceiling suspension vibration value, and node bolt looseness value as: Qxz n 、Xgz n 、Sdz n , according to the formula: GCF n =e1*Qxz n +e2*Xgz n +e3*Sdz n , calculate the risk factor GCF at the height of the stage n , e1, e2, and e3 are the preset weight coefficients of the stage support inclination value, ceiling suspension vibration value, and node bolt looseness value, respectively. e1>e2>e3>0, and a1+a2+a3=3.512.

[0066] It should be noted that the stage height risk factor GCF nThe smaller the performance value, the lower the risk of failure in the corresponding upper part of the monitored object, that is, the safer it is; otherwise, the opposite is true.

[0067] Set the height risk factor range threshold, if the stage height risk factor GCF n If the height risk coefficient GCF is greater than or equal to the maximum value of the height risk coefficient range threshold, the monitored object is marked as a height risk signal; if the height risk coefficient GCF is greater than or equal to the maximum value of the height risk coefficient range threshold, the monitored object is marked as a height risk signal; n If the value of the height risk coefficient GCF is less than the maximum value of the height risk coefficient range threshold and greater than the minimum value of the height risk coefficient range threshold, the monitored object is marked as a high-altitude moderate risk signal; if the stage height risk coefficient GCF n If the value is less than or equal to the minimum value of the high-altitude risk coefficient range threshold, the monitored object will be marked as a high-altitude mild risk signal.

[0068] The risk characterization module 30 obtains risk signals corresponding to n monitored objects. If any monitored object has an emergency risk signal, an emergency maintenance mark is generated and sent to the maintenance personnel's mobile terminal. The stage power supply line is urgently cut off and the stage power supply line is checked to avoid safety accidents and improve the safety performance of digital operation.

[0069] If any monitored object has a low-level high-risk signal and a high-level high-risk signal, the corresponding monitored object will be marked as a high-risk mark; if any monitored object has a low-level high-risk signal and a high-level moderate-risk signal, a high-level high-risk signal and a low-level moderate-risk signal, or a low-level moderate-risk signal and a high-level moderate-risk signal, the corresponding monitored object will be marked as a moderate-risk mark; if any monitored object has a low-level moderate-risk signal and a high-level mild-risk signal, a high-level moderate-risk signal and a low-level mild-risk signal, or a low-level mild-risk signal and a high-level mild-risk signal, the corresponding monitored object will be marked as a mild-risk mark;

[0070] It should be noted that the intensity of different marks, from high to low, is emergency maintenance mark, high risk mark, medium risk mark, and light risk mark; when an emergency maintenance mark appears, the power supply to the entire stage should be cut off immediately, and the stage power supply line should be checked for hidden dangers; when high risk marks and medium risk marks appear at the same time, in the case of insufficient number of maintenance personnel, priority should be given to targeted maintenance of the monitoring area corresponding to the high risk mark to ensure the safe operation of the stage to the greatest extent; when a light risk mark appears, there is no need to operate it. The operation information of different areas of the stage can be obtained simultaneously through the digital information network to generate different risk marks, so that maintenance personnel can carry out emergency maintenance of the stage or corresponding targeted maintenance of a certain area of ​​the stage according to the risk marks of different intensities, improve maintenance efficiency, and deal with the fault before the fault risk occurs, which can avoid the occurrence of stage safety accidents to the greatest extent and improve the safety performance of stage operation.

[0071] Example 2

[0072] See also Figure 3 As shown, the stage safety system based on the digital information network described in this embodiment further includes a high-risk positioning module 40, a data analysis module 50, a first relay 5, a first pressure sensor 6, a second relay 7, and a vibration module 8; wherein the first pressure sensor 6 is installed on the bottom surface of the stage platform 2. When the stage platform 2 is stepped on, the first pressure sensor 6 can be pressurized and is in a closed circuit state. The first pressure sensor 6 is electrically connected to the first relay 5, and the first relay 5 controls the opening and closing state of the circuit of the first pressure sensor 6; the vibration module 8 is installed on a wearable device that moves with the stage performer, such as a vibrating bracelet, and the second relay 7 controls the opening and closing state of the circuit of the vibration module 8; the high-risk positioning module 40, the data analysis module 50, the first relay 5, and the second relay 7 are signal-connected, and specifically can be connected via Bluetooth signals.

[0073] The high-risk positioning module 40 is used to receive the high-risk mark, generate a first connection signal according to the high-risk mark, set a preset radius of m meters with the monitored object actually corresponding to the high-risk mark as the center, mark all stage decks 2 within the radius of m meters as risk transition areas, and send the first connection signal to all first relays 5 located in the risk transition area;

[0074] The first relay 5 connects the circuit for the first pressure sensor 6 according to the first connection signal; when the stage deck 2 is pressurized, the circuit outputs an electrical signal and sends it to the data analysis module 50;

[0075] The data analysis module 50 generates a second connection signal according to the electrical signal and sends it to the second relay 7; the second relay 7 connects the circuit for the vibration module 8 according to the second connection instruction, and the vibration module 8 is powered on and vibrates;

[0076] When the data analysis module 50 does not receive the electrical signal within the preset time, it generates a disconnection message and sends it to the second relay 7. The second relay 7 cuts off the circuit for the vibration module 8, and the vibration module 8 stops vibrating.

[0077] This embodiment sets a risk transition area around the monitoring object corresponding to the actual height risk mark. When a stage performer steps on the stage platform 2 in the risk transition area, the wearable device worn by the stage performer will start a vibration prompt, upgrading the stepped area to a risk area, and leaving in time to avoid stepping on the monitoring object corresponding to the actual height risk mark and causing a complete accident. While the maintenance personnel are performing maintenance, the stage performers are reminded, further reducing the occurrence of stage safety accidents and further improving the safety performance of stage operation.

[0078] The stage safety system of this embodiment also includes a light strip and a third relay. The light strip is embedded around the top surface of the stage platform 2. The third relay controls the on and off state of the light strip circuit. The high-risk positioning module 40 also generates a light strip connection signal based on the high-risk mark, and sends the light strip connection signal to all third relays located in the risk transition area. The third relay connects the light strip circuit, and the light strip emits a prompt light. Stage performers can more conveniently know the risk area based on the light of the light strip.

[0079] Example 3

[0080] See also Figure 4 As shown, the stage safety system based on the digital information network described in this embodiment further includes a second pressure sensor 9, which is connected to the data analysis module 50 via a wireless signal. The second pressure sensor 9 is installed under the stage deck 2. When the stage deck 2 is stepped on, the second pressure sensor 9 sends a pressure signal to the data analysis module 50. The pressure signal includes a pressure value. The data analysis module 50 records the number of pressure signals and the pressure values ​​exceeding the pressure threshold, and compares the number of pressure signals with the number range threshold. If the number of pressure signals is greater than or equal to the maximum value of the number threshold, replacement information is generated for the corresponding stage deck 2, and the stage maintenance personnel maintain or replace the screen glass on the surface of the corresponding stage deck 2.

[0081] If the number of pressure signals is less than the maximum value of the number threshold and greater than the minimum value of the number threshold, position replacement information is generated to facilitate the stage installers to install the stage platform 2 with the generated position replacement information at the edge of the stage when assembling the stage next time, thereby reducing its pressing frequency and installing other stage platforms 2 with fewer pressing times in areas with high pressing frequency, thereby improving the life of the entire stage platform 2 and reducing safety accidents caused by the breakage and cracking of the screen glass of the stage platform 2.

[0082] If the number of compressed signals is less than or equal to the minimum number threshold, no information is generated.

[0083] Maintenance information is generated for the stage deck 2 corresponding to the pressure value exceeding the pressure threshold. The maintenance information includes the position information of the corresponding stage deck 2. The maintenance personnel shall promptly reconfirm the corresponding stage deck 2 screen glass on site according to the guidance of the maintenance information to determine whether emergency maintenance is required, so as to avoid safety accidents caused by breakage and cracking of the stage deck 2 screen glass to the greatest extent.

[0084] The above formulas are all dimensionless and numerical calculations. The formulas are obtained by collecting a large amount of data and performing software simulation to obtain the most recent real situation.
