[0027] Due to space limitations, large-scale cultural performances often require the temporary construction of stages and stands in outdoor or larger indoor spaces. The basic structures of these temporary stages and stands are typically constructed using steel or aluminum structures such as interlocking steel pipe supports and aluminum alloy trusses.

[0028] Temporary stages have various complex load conditions, which are significantly different from those used in building construction. As the scale of temporary stages and stands for large-scale cultural performances continues to expand and the structural complexity increases, the probability of accidents such as collapse and overturning of temporary structures also increases.

[0029] Based on the aforementioned technical problems, this utility model embodiment is proposed. This utility model embodiment may include a workstation device 1, a network connection device 2, and a sensing layer device.

The stage equipment operational status data includes at least one of the following: equipment temperature data, equipment ambient humidity data, and equipment current data. Therefore, by monitoring the health status of the temporary structure and the operational status of the stage equipment through the workstation device 1, abnormal structural changes and equipment operating states can be detected in a timely manner, reducing the probability of safety accidents involving the temporary structure and equipment.

[0030] Please see Figure 1-3 This utility model provides a dynamic monitoring system for the status of temporary performance structures and stage equipment. The system may include a workstation device 1, a network connection device 2, and a sensing layer device. The network connection device 2 is electrically connected to the workstation device 1. The sensing layer device is electrically connected to the network connection device 2 to detect the health status data of the temporary performance structures and the operating status data of the stage equipment. The sensing layer device includes at least one of the following: an inclination sensor 3, a stress-strain sensing unit 4, a tension sensing unit 5, a deformation detection sensing device 8, a deformation detection sensing unit, a settlement detection sensing unit, a vibration sensing unit 6, a meteorological sensing unit 7, a temperature sensor 9, a humidity sensor 10, and a current sensing unit 11. The health status data includes at least one of the following: structural inclination data, stress-strain data, cable tension data, structural deformation data, structural vibration data, and meteorological data. The stage equipment operating status data includes at least one of the following: equipment temperature data, equipment ambient humidity data, equipment ambient temperature data, and equipment current data.

[0031] In this embodiment of the invention, the workstation device 1 can be understood as a high-performance computer system, typically used in scenarios involving complex calculations, graphics processing, and data processing. The workstation device 1 can be an industrial control computer or a laptop computer. The workstation device 1 may contain a server, database, operating system, and applications for use with a monitoring system; however, no further limitations are specified here.

[0032] The workstation device 1 can be electrically connected to the network connection device 2. For example, a communication connection can be established wirelessly or via a wired connection. The network connection device 2 refers to hardware devices that realize network communication and data transmission. For example, the network connection device 2 includes, but is not limited to: network switch 22, router, wireless WIFI device, wireless NB-IoT (Narrowband Internet of Things) device, wireless 4G / 5G device, and gateway device, etc. For example, the gateway device may include at least one of the following: LoRaWAN (Long Range Wide Area Network) gateway, ZigBee gateway, data transmission unit gateway, WIFI gateway, Ethernet gateway, and wireless mobile communication network gateway. The gateway device establishes a communication connection with the sensing layer device via wireless or wired connection.

[0033] In the case where the network connection device 2 includes a network switch 22 and the gateway device, the network switch 22 forms communication connections with the workstation device 1 and the gateway device, respectively. The communication protocol between the network switch 22 and the workstation device 1 includes one of the following: MQTT (Message Queuing Telemetry Transport), TCP (Transmission Control Protocol), HTTP (Hypertext Transfer Protocol), PPPoE (Point-to-Point Protocol over Ethernet), and Coap (Constrained Application Protocol). Those skilled in the art can determine the communication method between the network switch 22 and the workstation device 1 according to actual design requirements, and no further limitations are made here. In some embodiments, the perception layer device communicates directly with the network switch 22. In other embodiments, the perception layer device communicates directly with the workstation device 1. In still other embodiments, the perception layer device communicates indirectly with the network switch 22 through the gateway device. Those skilled in the art can determine the communication method of the perception layer device according to actual design requirements, and no further limitations are imposed here.

[0034] The network connection device 2 belongs to the network layer device of the Internet of Things (IoT) architecture, and the workstation device 1 belongs to the application layer device of the IoT architecture. The sensing layer device is a fundamental component of the IoT architecture, which acquires data such as physical, chemical, and biological quantities in the environment through sensors and other devices. For example, the sensing layer device may include at least one of the following: tilt sensor 3, stress-strain sensing unit 4, tension sensing unit 5, deformation detection sensing device 8, deformation detection sensing unit, settlement detection sensing unit, vibration sensing unit 6, meteorological sensing unit 7, temperature sensor 9, humidity sensor 10, and current sensing unit 11.

[0035] The tilt sensor 3 refers to a sensor used to measure the tilt angle of an object relative to a horizontal plane. The tilt sensor 3 is located on the pillars (or support frames, etc.) of the temporary performance structure. For example, it is used to detect the structural tilt angle data of the temporary performance structure on the pillars. Thus, it can be determined whether the pillars are tilted using the structural tilt angle data of the temporary performance structure. In one or more embodiments, the tilt sensor 3 is electrically connected to the network connection device 2 to transmit the detected structural tilt angle data of the temporary performance structure to the workstation device 1.

[0036] The stress-strain sensing unit 4 is installed on the stress-strain area of ​​the temporary structure used for the performance and is used to detect stress-strain data related to the stress-strain area. In some embodiments, refer to... Figure 3 As shown, the stress-strain sensing unit 4 may include a strain gauge 41 and a stress-strain node 42. The strain gauge 41 is a sensing element that converts strain on a mechanical component into a measurable electrical signal, used to detect the stress-strain data of the temporary structure used in the performance. The stress-strain node 42 refers to a device for processing the sensing data from the strain gauge 41. For example, the stress-strain node 42 and the strain gauge 41 can be electrically connected by a wire, and the stress-strain node 42 can amplify and convert the sensing signal output by the strain gauge 41 into a digital signal for processing. The stress-strain node 42 may be a LoRaWAN (Long Range Wide Area Network) wireless stress-strain node (based on the LoRaWAN protocol, used to measure and monitor the stress-strain state of an object and transmit data wirelessly).

[0037] In other embodiments, reference is made to... Figure 2 As shown, the stress-strain sensing unit 4 may further include a stress gauge 43. The working principle of the stress gauge 43 is mainly based on the strain-stress relationship of materials (Hooke's Law), that is, within the elastic deformation range of an object, stress is directly proportional to strain. The stress gauge 43 is electrically connected to the network connection device 2 to monitor the stress-strain data of the temporary structure used for the performance. The stress-strain data detected by the stress gauge 43 can be uploaded to the workstation device 1 through the network connection device 2.

[0038] The tension sensing unit 5 refers to an instrument used to measure the magnitude of tension on an object. It is installed on the cables of a temporary performance structure to monitor the tension (also known as tensile force) of the cables. This allows for the collection of tension data from the cables of the temporary performance structure. For example, the tension sensing unit 5 may include a tension sensor 51 and a tension node 52. The tension sensor 51 detects the tension data of the cables in the temporary performance structure. The tension node 52 refers to a device for processing the sensing data from the tension sensor 51. For example, the tension node 52 and the tension sensor 51 can be electrically connected by a wire, and the tension node 52 can amplify and convert the sensing signal output by the tension sensor 51 into a digital signal for processing, and output the tension data related to the cable. The tension node 52 may be a LoRaWAN wireless tension node 52 (a device based on the LoRaWAN protocol used to measure and transmit tension data wirelessly). Based on the network connection device 2, the cable tension data can be uploaded to the workstation device 1. In some embodiments, the tension sensor 51 may be selected from devices such as a pressure-side tension sensor 51.

[0039] The deformation detection sensor 8 refers to a related sensing device used to detect structural deformation data. For example, the deformation detection sensor 8 can be used to detect the structural displacement data of the temporary structure used for the performance. The deformation detection sensor 8 is electrically connected to the network connection device 2, so that when the deformation detection sensor 8 detects structural displacement data, it can upload it to the workstation device 1 through the network connection device 2. Thus, the workstation device 1 can monitor the structural displacement data of the temporary structure used for the performance. The structural deformation data includes at least one of the following types: structural displacement data, structural deflection data, and structural settlement data. Correspondingly, refer to... Figure 3 As shown, the deformation detection sensing device 8 may include: a distance sensor 81, a video displacement meter 82, a displacement measuring instrument 84, and / or a scanner 83.

[0040] In some examples, the ranging sensor 81 can be a radar ranging sensor 81, which is electrically connected to the network connection device 2 to detect the structural displacement data of the temporary structure used for the performance. For example, the radar ranging sensor 81 can establish a wireless connection with the network connection device 2 via the LoRaWan protocol. Thus, the structural displacement data (e.g., horizontal displacement and vertical settlement) of the temporary structure can be detected wirelessly by the radar ranging sensor 81 and transmitted to the workstation device 1 for display via the network connection device 2. Therefore, if abnormalities in the structural displacement data are observed, timely warnings or remedial measures can be taken to avoid safety accidents such as stage collapse due to excessive changes in the structural displacement data of the temporary structure. As another example, the ranging sensor 81 can also be an ultra-wideband ranging sensor 81, etc.

[0041] In some embodiments, reference is made to Figure 3 As shown, the video displacement meter 82 is a device based on video image analysis technology used to accurately measure changes in object displacement. The video displacement meter 82 is wired to the network connection device 2, thereby improving the transmission efficiency of video data. The video displacement meter 82 can be directly facing the temporary stage structure used for performances, allowing for the detection of data such as structural displacement, deflection, and settlement. In one or more embodiments, the dynamic monitoring system for the temporary stage structure and stage equipment may further include a machine vision measurement device, which is wired to the network connection device 2 and used to detect data such as structural displacement, deflection, and settlement of the temporary stage structure.

[0042] In some embodiments, the displacement measuring instrument 84 is an instrument used to accurately measure changes in the position of an object (i.e., displacement). It converts the displacement of the object (such as linear displacement or angular displacement) into readable electrical signals, digital signals, or visual data for monitoring, analysis, or control. Thus, the displacement measuring instrument 84 can detect data such as structural displacement, structural deflection, and structural settlement of the temporary structure used for the performance. This data is then uploaded to the workstation device 1 via the network connection device 2.

[0043] In some embodiments, reference is made to Figure 3As shown, the scanner 83 is a measuring device that integrates multiple functions such as angle measurement, distance measurement, photogrammetry, and 3D scanning, and can be used to acquire spatial location information. For example, the scanner 83 can scan and inspect the temporary structure used for performances, detecting data such as structural displacement, structural deflection, and structural settlement. The scanner 83 is electrically connected to a DTU (Data Transfer Unit) gateway. This allows the serial port (e.g., RS232 serial port) data transmitted by the scanner 83 to be converted into Internet Protocol (IP) data. This facilitates the wired or wireless transmission of the structural scan data from the scanner 83 to the workstation device 11. For example, in scenarios where external network access is prohibited (mobile communication network access is prohibited), a wired connection to the network switch 22 can be used. In scenarios where external network access is permitted, a wireless connection can be used for remote transmission.

[0044] In summary, the workstation device 1 can receive and display the structural tilt angle data, stress-strain data, and tension data of the temporary performance structure. This allows maintenance personnel to monitor structural changes in the temporary performance structure, promptly detect abnormal changes, and take timely remedial measures, reducing the probability of safety accidents such as collapse and overturning of the temporary structure.

[0045] The meteorological sensor unit 7 is used to detect meteorological data of the environment in which the temporary performance structure is located. (Refer to...) Figure 2 and Figure 3As shown, the meteorological sensing unit 7 may include a data acquisition unit 71 and a meteorological sensor 72. The data acquisition unit 71 is electrically connected to the network connection device 2. The meteorological sensor 72 is electrically connected to the data acquisition unit 71 to detect the meteorological data. The meteorological sensor 72 may be installed on the temporary structure for the performance or in an area near the temporary structure, thereby detecting the meteorological data of the environment in which the temporary structure for the performance is located. The meteorological sensor 72 may include at least one of the following types: temperature sensor 9, humidity sensor 10, wind speed sensor, and wind direction sensor, etc. Correspondingly, the meteorological data may include at least one of the following types: ambient temperature data, ambient humidity data, ambient wind speed data, and ambient wind direction data, etc. For example, the meteorological sensor 72 may be a four-element meteorological station, which is a device capable of real-time monitoring and data acquisition of four key elements in the meteorological environment: temperature, humidity, wind speed, and wind direction. Therefore, the data from the four-element meteorological station can be converted and output to the workstation device 1 through the multi-functional data acquisition device 718, and the environmental temperature data, environmental humidity data, environmental wind speed data and environmental wind direction data can be displayed through the workstation device 1.

[0046] For example, the four-element weather station can be an RS485-based station (or another communication protocol). That is, the four-element weather station and the data acquisition unit 71 are electrically connected via an RS485 bus. The data acquisition unit 71 and the network connection device 2 can establish a communication connection based on the LoRaWAN protocol. For example, the data acquisition unit 71 can establish a communication connection with the LoRaWAN gateway 21 in the network connection device 2. The LoRaWAN gateway 21 then establishes a communication connection with the workstation device 1 via the network switch 22 based on the MQTT (Message Queuing Telemetry Transport) protocol.

[0047] The data acquisition unit 71 is a device for collecting, storing, and transmitting various types of data. It is electrically connected to the meteorological sensor 72, converting the analog or digital signals detected by the sensor into digital data for processing by the workstation device 1, and is also electrically connected to the network connection device 2. This allows the meteorological data detected by the meteorological sensor 72 to be processed and stored accordingly, and then transmitted to the workstation device 1 via the network connection device 2 for subsequent analysis, monitoring, and decision-making by the workstation device 1.

[0048] By monitoring meteorological data of the temporary stage structure used for performances, stage maintenance personnel can be alerted to take timely remedial measures when abnormal meteorological data occurs in different areas of the stage. This includes preventing performers from suffering heatstroke or hypothermia. Furthermore, monitoring outdoor weather conditions can prevent rain from wetting stage equipment and causing electrical leaks or other safety accidents.

[0049] Reference Figure 2 and Figure 3 As shown, the vibration sensing unit 6 is used to detect the structural vibration data of the temporary structure used for the performance. For example, refer to... Figure 2 and Figure 3 As shown, the vibration sensing unit 6 may include a vibration sensor node 61, which is electrically connected to the network connection device 2 to detect structural vibration data of the temporary structure used for the performance. The vibration sensor node 61 is a device for sensing and collecting vibration information. It can be used to detect structural vibration data in different areas of the temporary structure; for example, the vibration sensor node 61 can be placed in areas such as the stage surface, columns, or audience stands. The vibration sensor node 61 can form a wireless connection with the ZIGBEE gateway, thereby improving the detection speed of the structural vibration data. Furthermore, the structural vibration data can be uploaded to the workstation device 1 through the network connection device 2. The main purpose of detecting the structural vibration data is to avoid excessive vibration or resonance, thereby reducing the risk of collapse of the temporary structure used for the performance. In another example, the vibration sensing unit 6 may include components such as strain gauge vibration sensors, which are not further limited here.

[0050] The current sensing unit 11 is used to detect changes in the operating current of the stage equipment. For example, the current sensing unit 11 may include a current sensor 111. For example, the current sensor 111 may be a current-temperature mutual inductance sensor. The current-temperature mutual inductance sensor is a device used to measure current and temperature and transmit data wirelessly. It can integrate current detection and temperature detection into the same sensor, thus completing the monitoring of temperature data and equipment current data. This can reduce the number of sensors in the dynamic monitoring system for the temporary stage structure and stage equipment, and improve the ease of installation of the dynamic monitoring system for the temporary stage structure and stage equipment. The current-temperature mutual inductance sensor is electrically connected to the power distribution box of the temporary stage structure to detect the equipment temperature data and equipment current data of the power distribution box. The current-temperature mutual inductance sensor is also electrically connected to the network connection device 2 to transmit the equipment temperature data and equipment current data of the power distribution box to the workstation device 1. This allows for timely warnings or remedial measures when excessive current or temperature is observed in the power distribution box, reducing the probability of safety accidents caused by overcurrent or excessive temperature in the power distribution box. Among them, the distribution box that uses current and temperature mutual inductance sensors can refer to the distribution box whose current changes slowly for its electrical equipment.

[0051] In another example, refer to Figure 2 and Figure 3 As shown, the current sensing unit 11 may further include a Rogowski coil current sensor 112 and a current node 113. The Rogowski coil current sensor 112 is installed on the distribution box of the temporary structure used for the performance to detect the equipment current data output by the distribution box. The current node 113 is electrically connected to the Rogowski coil current sensor 112 and to the network connection device 2. The Rogowski coil current sensor 112 is a non-contact current sensor 111 based on the principle of electromagnetic induction; it can measure the current by placing it on the conductor being measured. This improves the safety and accuracy of current detection. The current node 113 is a device for sensing and transmitting equipment current data. For example, the current node 113 can be a ZigBee wireless current sensor 111 node. The distribution box can be a device that provides power to stage lights. Since the current of stage lights changes rapidly during operation, the electrical connection between the Rogowski coil current sensor 112 and the current node 113 allows the device current data to be amplified and converted via the current node 113, and then transmitted to the workstation device 1 via the network connection device 2. This enables timely detection of device current data in case of malfunctions during the operation of the distribution box, allowing for proactive maintenance and repair, and improving the operational stability of the distribution box.

[0052] For example, the Rogowski coil current sensor 112 and the current node 113 can be electrically connected by a wire. The current node 113 can establish a communication connection with the ZigBee gateway 23 in the network connection device 2 based on the ZigBee protocol. The ZigBee gateway 23 then establishes a communication connection with the network switch 22 based on the MQTT protocol, thereby enabling stable signal transmission. The use of a wireless connection method can improve the deployment efficiency of the dynamic monitoring system for the temporary stage structure and equipment status, and the use of the ZigBee protocol can improve the monitoring speed of the equipment current data, thus enabling timely detection of anomalies in the equipment current data in scenarios with rapid current changes.

[0053] The temperature sensor 9 is used to detect the ambient temperature data of the stage equipment, and the humidity sensor 10 is used to detect the ambient humidity data of the stage equipment. In some embodiments, the temperature sensor 9 and the humidity sensor 10 can be an integrated structure, i.e., the temperature and humidity sensor 10 is selected. The stage equipment may include stage lights, stage sound systems, and stage video equipment, etc. (Refer to...) Figure 2 and Figure 3 As shown, the temperature sensor 9 and humidity sensor 10 are installed on the stage equipment of the temporary stage structure used for performances and are electrically connected to the network connection device 2 to detect the ambient temperature and humidity data of the stage equipment. The temperature sensor 9 and humidity sensor 10 can each form a wireless connection with the network connection device 2, and transmit the ambient temperature and humidity data to the workstation device 1 via the network connection device 2. In some examples, when the ambient temperature of the stage equipment is found to be too high based on the ambient temperature and humidity data, timely warnings or remedial measures are taken to reduce the probability of stage performance accidents or safety incidents caused by excessively high ambient temperatures. Alternatively, when the ambient humidity of the stage equipment is found to be too high based on the temperature and humidity data, timely warnings or remedial measures are taken to reduce the probability of stage performance accidents caused by the risk of malfunction due to excessively high ambient humidity.

[0054] An optional embodiment of the utility model, referring to... Figure 2 and Figure 3As shown, the sensing layer device may further include a vibration cable 12, a detector 13, and an alarm host. The vibration cable 12 detects edge vibration data generated when a person approaches the edge warning area of ​​the temporary structure for the performance. The detector 13 is electrically connected to the vibration cable 12 to transmit the edge vibration data. The vibration cable 12 refers to a device that uses the piezoelectric effect or electromagnetic induction principle to sense external vibrations. The vibration cable 12 can be arranged in straight lines, curves, or polygons, and installed in the edge warning area of ​​the temporary structure for the performance. When the vibration cable 12 is subjected to vibration excitation (e.g., vibration caused by a person walking near the cable), it outputs an electrical signal of a certain amplitude and frequency, which serves as edge vibration data of the adjacent edge warning area. After receiving the corresponding edge vibration data, the detector 13 compares it. If the threshold set on the detector 13 is met, the detector 13 issues an alarm message, which is then triggered by the alarm host electrically connected to it. Furthermore, the alarm host and the workstation device 1 are electrically connected. For example, they can communicate via an RS485 (Recommended Standard 485) bus or a CAN bus (Controller Area Network Bus). The alarm host and the network switch 22 can communicate via protocols such as TCP and MQTT to transmit the edge vibration data to the workstation device 1 for display. Therefore, using the vibration cable 12 to monitor the edge warning area of ​​the temporary structure can prevent personnel from falling or other safety incidents in the edge warning area where there is a significant height difference from the ground, thus improving the operational safety factor of the temporary structure.

[0055] In one optional embodiment of the utility model, referring to Figure 3As shown, the sensing layer device may further include a monitoring camera 14, which monitors images of personnel approaching the edge warning area of ​​the temporary structure used for the performance. The monitoring camera 14 is electrically connected to the network connection device 2. For example, the monitoring camera 14 can communicate with the network switch 22 via protocols such as TCP and MQTT. The monitoring camera 14 faces the edge warning area of ​​the temporary structure used for the performance, can capture images of the edge warning area, and perform image recognition on the captured images. If a person is detected within the edge warning area, a warning message can be output to the alarm host for alarm activation. Furthermore, the alarm host can establish a communication connection with the network connection device 2, such as the network switch 22, via a network cable, and upload the corresponding warning information to the workstation device 11. Through the dual monitoring of the monitoring camera 14 and the vibration cable 12, the operational safety factor of the temporary structure can be greatly improved.

[0056] In one optional embodiment of the utility model, referring to Figure 3 As shown, the sensing layer device may further include a thermal imager 15, which is electrically connected to the network connection device 2. The thermal imager 15 can be an infrared thermal imaging device, capable of monitoring the temperature distribution of stage equipment (including electrical connections) within the temporary structure. Specifically, it can acquire the equipment temperature data of the stage equipment. For example, the thermal imager 15 can collect thermal images of the temporary structure used for performances and transmit them via wired connection to the network connection device 2, and finally to the workstation device 1. Using wired transmission improves the transmission efficiency of the thermal images. Maintenance personnel can monitor the thermal images to promptly detect any abnormal overheating of the stage equipment, preventing equipment malfunctions or fires caused by overheating.

[0057] In some alternative implementations, refer to Figure 3 As shown, the dynamic monitoring system for the temporary stage structure and equipment used in the performance can also be connected to the on-site monitoring computer via network connection device 2, allowing for data querying and monitoring. The workstation device 1 can also be wirelessly connected to the cloud or multiple monitors, enabling the forwarding of data received by the workstation device 1. The cloud is a platform layer device. The cloud can also establish communication connections with remote terminals or mobile devices via mobile communication networks, and forward stage monitoring data through the cloud.

[0058] Based on the above system architecture, the structure of the temporary performance structure can be monitored using tilt sensor 3, stress-strain sensing unit 4, tension sensing unit 5, deformation detection sensing device 8, vibration sensing unit 6, and meteorological sensing unit 7. The operating status of the stage equipment can be monitored using temperature sensor 9, humidity sensor 10, and current sensing unit 11. Edge monitoring is also performed using monitoring camera 14 and / or vibration cable 12. Thus, the workstation device 1 monitors the health status of the temporary structure and the operating status of the stage equipment, promptly detecting abnormal structural changes, equipment operating status, and monitoring personnel entering the edge warning area, reducing the probability of safety accidents involving the temporary performance structure and equipment, as well as stage falls.
