Description

Technical Field

[0001] This invention relates to the field of highway bridge monitoring technology, specifically to an intelligent monitoring device and health management platform for highway bridge structures. Background Technology

[0002] As a crucial component of transportation infrastructure, highway bridges' safe operation directly impacts the safety of people's lives and property, as well as the normal development of the social economy. With increasing service life, growing traffic loads, and environmental erosion, highway bridges are prone to structural damage and performance degradation. Failure to detect and address these issues promptly can lead to serious safety accidents. Therefore, real-time and effective health monitoring of highway bridges is of paramount importance. Currently, most existing highway bridge monitoring equipment suffers from installation difficulties, making it hard to flexibly adjust installation positions and angles according to the structural characteristics and monitoring needs of different bridges. Furthermore, the equipment's protective capabilities are poor, making it susceptible to damage in harsh natural environments (such as high temperatures, heavy rain, and corrosion), affecting its lifespan and the accuracy of monitoring data. Simultaneously, existing monitoring equipment typically only collects data, lacking effective data processing and analysis capabilities. Monitoring data requires manual processing and analysis, which is not only inefficient but also hinders the timely detection of potential safety hazards in bridges. In addition, existing bridge health management systems are incomplete, lacking a unified health management platform for centralized management and comprehensive analysis of bridge monitoring data. This prevents a comprehensive and accurate assessment and early warning of bridge health status, and fails to provide scientific and effective decision support for bridge maintenance and management. Therefore, it is necessary to design an intelligent monitoring device and health management platform for highway bridge structures. Summary of the Invention

[0022] Please see Figures 1-3 The present invention discloses an intelligent monitoring device for highway bridge construction, including a fixing component, a monitoring component mounting frame 5, a protective shell 1, and a circuit module; The fixing assembly includes expansion bolts 2, a fixing base 3, and an adjusting bracket 4. The fixing base 3 is fixedly connected to the designated monitoring position on the highway bridge via the expansion bolts 2. One end of the adjusting bracket 4 is movably connected to the fixing base 3, and the other end is connected to the monitoring component mounting frame 5. The adjusting bracket 4 is equipped with locking bolts for locking the adjustment angle. The adjusting bracket 4 includes a first support rod 18 and a second support rod 19. One end of the first support rod 18 is hinged to the fixing base 3, and the other end is connected to one end of the second support rod 19 via a universal joint 20. The other end of the second support rod 19 is fixedly connected to the monitoring component mounting frame 5. The locking bolts are respectively located at the hinge point between the first support rod 18 and the fixing base 3 and at the universal joint connection point between the first support rod 18 and the second support rod 19. By adjusting the hinge angle between the first support rod and the fixing base, and the universal joint angle between the first support rod and the second support rod, the monitoring component mounting frame can be adjusted in different directions and angles, thereby meeting the requirements of different bridge structures and different monitoring indicators for the sensor installation position and angle, and improving the flexibility and applicability of the monitoring equipment. After adjusting to the appropriate angle, the angle of the adjustment bracket can be fixed by tightening the locking bolts to ensure that the monitoring equipment will not shift during use.

[0023] In this invention, the monitoring component mounting bracket 5 is a hollow frame structure, with multiple mounting slots and fixing clips inside for mounting circuit module components. The hollow structure not only reduces the weight of the mounting bracket and the load on the fixing components, but also facilitates airflow and improves the heat dissipation of the equipment. The mounting slots and fixing clips facilitate the installation and fixing of each circuit module component, ensuring the stability of each component on the mounting bracket and preventing loosening or damage due to vibration or other factors. It also facilitates later inspection and replacement of the components.

[0024] The protective housing 1 is fitted onto the outside of the monitoring component mounting bracket 5. The protective housing 1 has heat dissipation holes, and a dustproof mesh is installed inside the heat dissipation holes. A maintenance door 6 is connected to one side of the protective housing 1 via a hinge. The maintenance door 6 is equipped with a sealing strip and a door lock. The maintenance door facilitates the inspection and maintenance of the internal components of the equipment by the staff. The sealing strip can improve the sealing performance of the protective housing and prevent rainwater and moisture from entering the equipment. The door lock can prevent theft and prevent unauthorized personnel from opening the maintenance door at will.

[0025] In this invention, the circuit module includes a sensor module, a data acquisition and processing module 7, a wireless communication module 8, a power supply module 9, and an alarm module 10. The sensor module includes a strain sensor 11, a displacement sensor 2, a vibration sensor 13, a temperature sensor 14, and a humidity sensor 15. These sensors are mounted on the monitoring component mounting bracket 5 via mounting slots and fixing clips, with the detection end of each sensor extending beyond the protective housing 1. The strain sensor monitors the strain of the bridge structure under load to determine if there is stress concentration or excessive deformation. The displacement sensor monitors the displacement changes of the bridge structure, including vertical and horizontal displacement, to understand the settlement or offset of the bridge. The vibration sensor monitors the vibration signals generated by the bridge under vehicle traffic, wind loads, etc., to analyze the dynamic characteristics of the bridge and determine if there is damage to the bridge structure. The temperature and humidity sensors monitor the temperature and humidity changes in the environment where the bridge is located to understand the impact of environmental factors on the performance of the bridge structure, providing a reference for bridge maintenance and management.

[0026] In this invention, the data acquisition and processing module 7 includes a data acquisition card 16 and a microprocessor 17. The input terminal of the data acquisition card 16 is connected to the output terminal of the sensor module, and the output terminal of the data acquisition card 16 is connected to the input terminal of the microprocessor 17. The wireless communication module 8 is bidirectionally connected to the microprocessor 17 to realize data transmission between the monitoring device and an external health management platform. The data acquisition card is a 16-bit high-precision data acquisition card with high sampling accuracy and sampling rate, capable of accurately acquiring the analog signals output by each sensor and converting them into digital signals before transmitting them to the microprocessor. The microprocessor uses an STM32 series microcontroller, which has advantages such as high performance, low power consumption, and rich peripheral interfaces. It can quickly process and analyze the digital signals transmitted by the data acquisition card, including data filtering, noise reduction, and calculation, removing interference signals and outliers from the monitoring data and improving the accuracy and reliability of the monitoring data. Simultaneously, the microprocessor can also temporarily store the processed monitoring data and control the operation of other modules according to a preset program.

[0027] In addition, the wireless communication module 8 adopts a 4G / 5G communication module or a LoRa communication module. The wireless communication module can transmit the monitoring data processed by the microprocessor to the health management platform in real time. It can also receive control commands sent by the health management platform, such as parameter setting and data query commands, and transmit them to the microprocessor, which will then perform corresponding operations according to the commands.

[0028] The present invention also discloses a highway bridge construction health management platform, which is wirelessly connected to highway bridge construction intelligent monitoring equipment. The health management platform includes a data receiving module 21, a data storage module 22, a data processing and analysis module 23, a health status assessment module 24, an early warning module 25, and a human-computer interaction module 26. The data receiving module 21 is wirelessly connected to the wireless communication module 8 of the monitoring device and is used to receive monitoring data transmitted by the monitoring device. The data storage module 22 is connected to the data receiving module 21 and is used to store the received monitoring data and various types of data generated during the operation of the platform. The data processing and analysis module 23 is connected to the data storage module 22 and is used to preprocess and analyze the monitoring data. The preprocessing includes data filtering, noise reduction and outlier removal, and the analysis includes trend analysis and comparative analysis of the monitoring data. The health status assessment module 24 is connected to the data processing and analysis module 23. It pre-stores the standard threshold range and health assessment model of each monitoring indicator of the highway bridge. The health status assessment module assesses the health status of the bridge based on the processed monitoring data and the health assessment model, and obtains the health level. The early warning module 25 is connected to the health status assessment module 24. When the health level obtained by the health status assessment module is lower than the preset level, or the monitoring data exceeds the standard threshold range, the early warning module issues an early warning message. The human-computer interaction module 26 is connected to the data storage module 22, the data processing and analysis module 23, the health status assessment module 24, and the early warning module 25, respectively. It is used to display monitoring data, analysis results, health assessment levels, and early warning information. It also supports users to input operation commands through the human-computer interaction module to set parameters and query data on the platform.

[0029] The health assessment model employs a BP neural network-based model, trained using extensive historical bridge monitoring data and corresponding actual bridge health status data. The early warning module 25 includes an SMS early warning unit 28 and a platform pop-up early warning unit 27. The SMS early warning unit sends early warning information to pre-defined administrator mobile phones, while the platform pop-up early warning unit displays early warning prompts on the human-computer interaction module's interface.

[0030] Working principle: Determine the bridge monitoring location, fix the equipment base with expansion bolts, adjust the bracket angle and lock it; assemble each circuit module and install the protective shell, initialize the equipment parameters through the platform, and build the hardware foundation; after power supply, each sensor synchronously collects strain, displacement, vibration, and temperature and humidity data, and the data acquisition card initially filters out invalid signals; the microprocessor processes the data with an algorithm, packages it, and transmits it to the platform via a wireless module; if the data exceeds the emergency threshold, a local audible and visual alarm is triggered; the platform receives and stores the data, analyzes the data trend and compares it with the benchmark, and calls the BP neural network model to assess the bridge's health level; if the standard is met, an early warning is triggered, and management personnel are notified via pop-up window and SMS; management personnel take action according to the suggestions, record the results after processing, and the platform reviews and cancels the early warning, forming a closed loop.

[0031] In summary, this invention solves the problems of inconvenient installation, poor protective effect, untimely data processing, and imperfect health management of existing highway bridge monitoring equipment. It can monitor the health status of highway bridges in real time and accurately, providing a scientific basis for the maintenance and management of highway bridges, and has high practicality and promotion value.
