The feature vectors are compared with the pre-stored database. If the similarity exceeds a set threshold (≥95%), the user is determined to be legitimate. An opening command is sent to the terminal control door 32 through the communication module, triggering the control switch 33 to connect the door lock circuit.

[0030] Optionally, in some embodiments, the environmental monitoring module 4 is linked with the energy consumption monitoring module 2. This linkage is used to detect energy consumption data during the operation of the environmental monitoring module 4.

[0031] Specifically, when teaching the IoT course on smart construction, after the environmental monitoring module is activated by the control switch 43, the first sensor 41 periodically collects environmental data and transmits the data to the RTU controller 42. The RTU controller 42 calibrates and compresses the raw data and uploads it to the terminal control device 43 and the application platform module 8 via RS-485 or wireless network. The terminal control device 43 compares the data with a preset threshold. If PM2.5 exceeds 50μg / m³, the purification equipment is automatically activated. The application platform module 8 stores historical data and generates trend charts for teaching analysis.

[0032] Optionally, in some embodiments, the RFID management module 5 includes a reader and an electronic tag 52. The electronic tag 51 is disposed on the surface of the device in each module and stores the device information of the corresponding device. The reader reads the device information in the electronic tag 51 and displays it on the application platform module 8. The reader supports high-frequency or ultra-high-frequency radio frequency communication for reading or writing electronic tag data. The electronic tag 51 is affixed to the surface of the device in each module and stores device information, including device name, model, function description, and maintenance records.

[0033] Specifically, after the RFID management module 5 is activated by the control switch 52, the reader emits a radio frequency signal to activate the electronic tag 51 and read the device information stored therein; the reader uploads the data to the application platform module 8 via serial port (RS-232) or wireless (Wi-Fi); the application platform module 8 parses the data and displays the device details, while updating the device status log; in addition, the RFID management module also supports writing new maintenance records to the electronic tag via the reader.

[0034] Optionally, in some embodiments, the structural health monitoring module 6 includes a second sensor 61 and a DTU controller 62. The second sensor 61 includes a strain sensor or a vibration sensor. The data from the second sensor 61 is transmitted to the application platform module 8 via the DTU controller 62 for structural condition analysis.

[0035] Optionally, in some embodiments, the structural health monitoring module 6 is linked with the energy consumption monitoring module 2 to detect energy consumption data during the operation of the structural health monitoring module 6.

[0036] Specifically, after the structural health monitoring module is activated by the control switch 63, the second sensor 61 collects structural parameters (such as strain values, vibration acceleration, etc.) in real time and transmits them to the DTU controller 62 via analog signals (4~20mA) or digital signals (RS-485). The DTU controller 62 timestamps and encrypts the data and uploads it to the application platform module 8 via LoRa wireless communication technology. The application platform module 8 calls analysis algorithms (such as FFT frequency domain analysis and damage identification models) to generate a structural safety assessment report. If the data exceeds the threshold (such as strain exceeding 500με), the platform triggers an early warning and locates the abnormal point. At the same time, in experimental teaching, students can manually adjust the safety threshold.

[0037] Optionally, in some embodiments, the intelligent control module 7 includes: a steel support shaft force electric cylinder type automatic control software and hardware module 71, which adjusts the support force in real time through pressure sensor feedback and is monitored through the application platform module 8.

[0038] In this embodiment, after the intelligent control module 7 is activated by the control switch 72, the steel support axial force electric cylinder automatic control software and hardware module includes three electric cylinders, a steel support mold, and an axial force gauge. The electric cylinders located on both sides are used to apply loads and have built-in displacement monitoring functions. Based on the displacement monitoring data from the two electric cylinders and feedback from the axial force gauge, a closed-loop control algorithm, such as PID or adaptive control algorithm, is used to dynamically adjust the loading rate and force of the middle electric cylinder, ensuring uniform load distribution and compliance with preset thresholds. A pressure sensor monitors the axial force of the steel support in real time to ensure real-time adjustment of the support force. Simultaneously, the application platform module 8 performs remote monitoring and data analysis. If abnormal data is detected, execution can be stopped immediately, improving safety and efficiency.

[0039] Optionally, in some embodiments, the intelligent control module is linked with the energy consumption monitoring module to detect energy consumption data during the operation of the intelligent control module.

[0040] Optionally, in some embodiments, a power supply module is also included, the power supply module including: a main input circuit connected to a 220V AC power supply; Multiple backbone branches are connected to the main input circuit and output DC power at different levels, including 5V, 12V, and 24V. Each backbone branch provides a suitable power supply voltage for the video surveillance module's energy consumption monitoring module, face recognition module, environmental monitoring module, RFID management module, structural health monitoring module, intelligent control module, and application platform module. Specifically, the 5V power supply powers the RFID management module and face recognition module, the 12V power supply powers the video surveillance module and environmental monitoring module, and the 24V power supply powers the intelligent control module and structural health monitoring module.

[0041] It should be noted that there is only one main input circuit, and multiple backbone branches are connected in parallel. All backbone branches are first connected to energy consumption monitoring equipment, and then converted to low voltage through a transformer. The lines before the transformer are hidden to ensure operational safety.

[0042] Optionally, in some embodiments, the application platform module 8 is used to integrate data from each module, supporting the management, monitoring, and data storage of each module device, and the display screen 82 is used to display the data from each module.

[0043] Specifically, users can individually start and stop any module by controlling the switch. For example, turning off the face recognition module will cause the application platform module to update the communication permissions of that module synchronously; or turning off the RFID management module will cause the application platform module to automatically start the local storage function to store data, and the display screen can dynamically display the data of each module, including charts, 3D models and alarm information.

[0044] The teaching aids provided in this embodiment for the Internet of Things (IoT) course in smart construction cover typical modules in the application scenarios of IoT technology in smart construction, including video surveillance modules, energy consumption monitoring modules, face recognition modules, environmental monitoring modules, RFID management modules, structural health monitoring modules, intelligent control modules, and application platform modules. These aids in teaching or learning IoT knowledge in smart construction, enabling students to master the application scenarios of IoT technology in smart construction.

[0045] Furthermore, in the teaching aids provided in this embodiment, the hardware devices of each module are fixedly integrated on a perforated board, facilitating replacement and maintenance. Each module comprehensively covers factor analysis at various levels, equipment selection, and module architecture. For example, each module extracts classic application scenarios of IoT technology in smart construction, and completes the hardware and software module construction based on the basic architecture of the IoT sensing layer, network layer, and application layer. Any module can be used as an example; based on the analysis of the monitoring or management factors of that module, equipment selection and module architecture analysis can be conducted. This facilitates the cultivation of skills in applying IoT technology to solve complex problems in smart construction projects.

[0046] Example 2 This utility model also provides a method for using a teaching aid for a smart construction Internet of Things course, see below. Figure 3 As shown, the specific steps include: S11. Start the target module via the control switch; S12. View the real-time data and operating status of the target module through the application platform module; S13. Conduct module linkage or independent function training according to the application scenario; S14. Turn off the power after the training is completed.

[0047] Specifically, during practical training, after confirming that the main power supply and backbone branch power supply of the teaching aids are normal, turn them on. Based on different application scenarios, start the target module by controlling the switch. For example, turn on the control switch 12 of the video monitoring module, use the RFID management module to scan the device tag, obtain the device information of the target module, and start the host of the application platform module. Display the image data collected by the camera in real time on the screen.

[0048] During module linkage training, for example in the scenario where the steel support axial force is automatically adjusted when energy consumption exceeds the limit, the energy consumption monitoring module, structural health monitoring module, and intelligent control module are activated by controlling the switch. At the same time, the host of the application platform module is activated. The energy consumption monitoring module and structural health monitoring module upload data to the application platform module in real time. The application platform module analyzes the energy consumption data and triggers the control strategy. The intelligent control module receives the control command and adjusts the steel support axial force.

[0049] Specifically, the energy consumption monitoring module monitors energy consumption data such as electricity, water, and gas in real time and uploads it to the application platform module. The application platform module presets energy consumption thresholds (e.g., electricity consumption exceeding 5 kWh per unit time). When the platform detects excessive energy consumption, it generates an early warning event and triggers a linkage process. The application platform module retrieves data from the structural health monitoring module (e.g., strain, displacement, vibration) to determine if the current structure allows for axial force adjustment. If the structure is in a critical state (e.g., displacement exceeds the limit), an alarm is prioritized over adjustment to avoid risk. Then, the application platform module sends a control command to the intelligent control module, specifying the target value for axial force adjustment (e.g., reducing axial force by 10% to reduce energy consumption). A servo motor drives a hydraulic pump to adjust the axial force of the steel support, providing real-time feedback data to the application platform module. After adjustment, the application platform module re-verifies the energy consumption and structural data to ensure the expected results are achieved.
