Description

Technical Field

[0001] This utility model relates to the field of building structure monitoring technology, specifically a wireless multi-functional structural safety monitoring device. Background Technology

[0002] A structural safety monitoring instrument is a device used to monitor the safety performance of a building or structure in real time. It can monitor various structural indicators such as displacement, settlement, tilt, vibration, and acceleration, as well as environmental parameters such as temperature and humidity. This monitoring data is crucial for assessing the health of the structure, promptly identifying potential safety hazards, preventing accidents, and guiding structural maintenance and reinforcement.

[0003] The problems with monitoring equipment and instruments currently available in the domestic market include: limited parameters, low integration, inability of a single device to achieve simultaneous monitoring of multiple sensors, and complex installation and dismantling work, which greatly limits the monitoring effect in locations where wiring is not available. In addition, existing monitoring instruments usually only have a single power supply method, which limits the usage time of the instruments and equipment. As for the use of solar panels for power supply, since the solar panels are usually fixed on the monitoring instrument, the conversion efficiency is low, which also affects the use of the monitoring instrument.

[0004] Therefore, this research focuses on developing a device that integrates multiple sensors into a single unit to achieve comprehensive monitoring, reducing the number of sensors required and the complexity of on-site wiring. It also aims to improve the lifespan of the monitoring instrument through optimized structural design and multiple power supply options. The goal is to create an intelligent monitoring product that can monitor the acceleration changes under displacement, settlement, and stress conditions of buildings, appurtenances, slopes, and walls. 。 Utility Model Content

Furthermore, existing monitoring instruments typically employ only a single power supply method, restricting their operating time. While solar panel power supply is available, its conversion efficiency is low due to the fixed installation of solar panels on the instrument, thus affecting its usability.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] Please see Figure 1 - Figure 7 This embodiment of a wireless multi-functional structural safety monitoring device includes a housing 1 and a main unit 2. A card plate 3 is installed at the bottom of the main unit 2. A motherboard 4 is installed inside the cavity of the main unit 2 and the motherboard 4 is located on top of the card plate 3. A display screen 13 is embedded in the front of the housing 1. Mounting bases 17 are connected to both sides of the main unit 2. The entire monitoring device can be installed on the building structure to be monitored through the mounting bases 17.

[0028] Furthermore, the box body 1 and the main unit box 2 are provided with a power supply structure, which includes a mounting block 5, an electric telescopic rod 6, a wedge-shaped connecting block 7, a bending plate 8, a first PET solar panel 9, a second PET solar panel 10, a storage battery 11 and a lithium-ion battery 12. Two sets of mounting blocks 5 are installed on the outer walls of both sides of the box body 1. Multiple sets of electric telescopic rods 6 are embedded on the opposite outer side of the mounting blocks 5. One end of the rod head of the multiple sets of electric telescopic rods 6 is connected to a wedge-shaped connecting block 7. Two sets of bending plates 8 are installed on the opposite outer side of the two sets of wedge-shaped connecting blocks 7. Multiple sets of first PET solar panels 9 are installed on the opposite outer side walls of the two sets of bending plates 8. A second PET solar panel 10 is installed on the top of the box body 1. The storage battery 11 is installed on the bottom wall of the inner cavity of the box body 1. The lithium-ion battery 12 is installed inside the cavity of the main unit box 2 through a support plate, and the lithium-ion battery 12 is located above the main board 4.

[0029] Furthermore, the box body 1 has a multi-faceted structure. Through the cooperation of the mounting block 5, the electric telescopic rod 6 and the wedge-shaped connecting block 7, bent plates 8 parallel to the sides of the box body 1 are installed on both sides. Four sets of first PET solar panels 9 are installed on different surfaces of the two sets of bent plates 8. A set of second PET solar panels 10 is located on the top of the box body 1. During use, the extension of one end of the electric telescopic rod 6 drives the bent plates 8 on both sides away from the box body 1, so that the second PET solar panels 10 on the top of the box body 1 can be fully exposed to the outside. Combined with the multiple sets of first PET solar panels 9 installed at different positions on both sides of the box body 1, the solar panels form a semi-enclosed structure, increasing the solar radiation receiving area of ​​the PET solar panels, thereby improving the efficiency of the PET solar panels in converting solar energy into electrical energy. The converted electrical energy is stored in the battery 11 for the use of the equipment. At the same time, it is combined with a large-capacity lithium-ion battery 12. The use of two power supply methods, namely the large-capacity lithium-ion battery 12 and the built-in battery 11, ensures that the overall building structure safety monitoring equipment can be effectively and sufficiently powered, and improves the service life of the monitoring equipment.

[0030] Furthermore, the motherboard 4 is electrically connected to the storage battery 11 and the lithium-ion battery 12 via wires. The motherboard 4 integrates a main control chip 14, a MEMS sensing module 15 and a communication module 16. The MEMS sensing module 15 is connected to the main control chip 14. The MEMS sensing module 15 also includes a tilt sensor 1501, a stress sensor 1502, an acceleration sensor 1503, a hydrostatic level sensor 1504 and a temperature and humidity sensor 1505. The communication module 16 also includes a LoRa module and a 4G module.

[0031] Furthermore, the sensors 1501, 1502, 1503, 1504, and 1505 are all located at the bottom of the card plate 3. Employing MEMS sensor technology based on microelectronic and micromechanical components, they accurately monitor the acceleration, angle, temperature and humidity, internal wall stress, and settlement changes of the building structure. They utilize minute amplitudes of angle and acceleration changes for precise micro-variable acquisition, ensuring excellent accuracy and stability of the monitoring data. By combining tilt acceleration with internal wall stress, they monitor the acceleration and angle changes of the building surface, main beams, and columns, as well as the direction of internal stress changes. By combining acceleration, angle changes, temperature and humidity changes, and internal stress magnitude, when the monitored data reaches a threshold, the main control chip 14 can determine the condition of the data and the direction of force applied, comprehensively assessing the health status of the monitored structure.

[0032] Furthermore, the monitoring data is wirelessly connected to the external network via the communication module 16, and data is transmitted and received via LoRa or 4G modules. Within the communication range of the LoRa module, multiple modules can communicate with each other. When using 4G for communication, information can be sent to the terminal platform, and messages sent by the terminal platform can also be received. When a message that needs to be sent is detected or received, it can be sent via the LoRa or 4G module. Various monitoring data are collected periodically or in real time, and the data is sent to the central server via wireless transmission.
