Description

Technical Field

[0001] This utility model relates to the field of disaster prevention and mitigation and bridge monitoring technology in highway transportation, and in particular to a simple sensing alarm device for bridge monitoring. Background Technology

[0002] Bridges, as vital passageways connecting rivers, straits, and other natural obstacles, directly impact the smooth flow of transportation and the safety of people's lives and property. However, due to natural environmental factors (such as continuous rainfall, flash floods, mudslides, landslides, and collapses caused by melting snow and ice), as well as the wear and tear and aging that bridges may suffer during long-term use, coupled with human factors such as overloading and impacts, bridge collapses occur frequently, causing enormous economic losses and adverse social impacts. Therefore, real-time bridge collapse monitoring is of paramount importance.

[0003] Traditional monitoring solutions primarily involve deploying various types of sensors on the bridge, along with different data acquisition devices, to obtain real-time information on changes in bridge characteristics. This approach results in a complex system architecture, high construction costs, excessively long data acquisition and transmission links, and delayed alarm responses. Consequently, it is difficult to implement on a large scale, especially in remote mountainous areas without electricity or internet access.

[0004] Therefore, how to further reduce the cost of monitoring equipment, especially by directly utilizing relatively inexpensive components and materials currently available on the market to achieve bridge monitoring and alarm, while also ensuring that the structure of the solution is simple enough to be easy to manufacture and install.

[0018] This utility model embodiment provides a simple sensing and alarm device for bridge monitoring, such as... Figure 1-3 As shown, the structural components of the simple sensing alarm device include: a lower shell (8), a battery compartment (9), a circuit board (10), a shell sealing ring (11), an upper shell (12), a solar panel (7), and a waterproof plate (13);

[0019] The upper surface of the upper shell (12) is provided with two layers of grooves. The size of the upper groove matches the size of the waterproof plate (13), and the size of the lower groove matches the size of the solar panel (7). The solar panel (7) is installed in the lower groove, and the waterproof plate (13) is installed in the upper groove. The size of the transparent part of the waterproof plate (13) matches the size of the solar panel (7) and covers the solar panel (7).

[0020] The upper shell (12) is installed above the lower shell (8) by fixing screws (14). After installation, the upper shell (12) and the lower shell (8) form a sealed internal cavity. The contact part between the upper shell (12) and the lower shell (8) is padded with a shell sealing ring (15).

[0021] The battery compartment (9) is fixedly installed in the internal cavity, and the circuit board (10) is fixedly installed on the upper surface of the battery compartment (9);

[0022] The power control module (5) is connected to the battery pack module (6), which is installed in the battery compartment (9) and connected to the solar panel (7) via wires.

[0023] Specifically, a microprocessor module (2) and a sensor group (1), a data cache module (3), a wireless communication module (4), and a power control module (5) connected to the microprocessor module (2) are soldered and installed on the circuit motherboard (10). An SMA waterproof connector and a five-pin waterproof aviation plug are installed on the side of the lower shell (8).

[0024] The sensor group (1) includes a vibration sensing unit, a tilt sensing unit, and a temperature measurement unit. The vibration sensing unit is an ADI ADXL355, the tilt sensing unit is an ADI ADIS16209, and the temperature measurement unit is an ADI DS18B20. A microprocessor module (2) and the sensor group (1), data cache module (3), wireless communication module (4), and power control module (5) connected to the microprocessor module (2) are soldered and mounted on the circuit board (10).

[0025] The microprocessor module (2) uses STMicroelectronics' STM32L431, the data cache module (3) uses Winbond's W25Q64JVSSIQ, the wireless communication module (4) uses Quectel's BC260Y communication module, the power control module (5) uses TI's TPS63020 module, the battery pack module (6) uses GA18650 lithium battery, and the solar panel (7) uses a 5V, 100mA solar panel.

[0026] The waterproof plate (13) is made of acrylic sheet, the lower shell (8) and the upper shell (12) are made of aluminum alloy permanent shell, and the shell sealing ring (15) is made of silicone. The five-core waterproof aviation connector is an M12, five-core waterproof aviation connector; the SMA waterproof connector is an SMA male to female high-frequency jumper.

[0027] In practical applications, such as Figure 1As shown, the sensor group (1) is a multi-parameter sensing unit (vibration, tilt angle, temperature) responsible for continuously and synchronously collecting vibration, tilt angle, and temperature data, and sending the measured data to the microprocessor module 2; the microprocessor module 2 can perform edge processing on the collected data through a pre-installed / burned general program, and the processed data is transmitted to the cache module 3. The main function of these general programs is to perform simple threshold judgment. In practical applications, technicians can also set up a multi-level warning mechanism. The multi-level warning mechanism is to set several different thresholds and issue corresponding electrical signals after threshold judgment in the program. This type of simple numerical judgment program is implemented directly using existing technologies and program packages, such as the official program package that comes with STM32L431. Therefore, it can be seen that all the technical means related to computer programs in this embodiment can adopt existing technologies. These technologies are often directly provided by the manufacturers of components purchased on the market, or they can be compiled using currently widely used programming languages ​​and methods already available in textbooks and existing technical literature. For example, judging the simple numerical value based on a preset threshold is a very simple and easily implemented function that can be easily implemented by those skilled in the art. Therefore, it will not be described in detail in this embodiment.

[0028] After the electrical signal triggers the alarm, the alarm information and measurement data are sent to the cloud platform through the wireless communication module 4; the battery module 6 is charged through the solar panel 7, and then the power control module 5 is connected to the microprocessor module 4 to supply power to the entire system; the solar panel 7 is placed on the top of the shell, and the other modules are placed inside the shell.

[0029] Installing this device on a bridge is also very simple. The first step for the installer is to securely fix the device to the structure being tested; the second step is to turn on the switch to start the device; the third step is to record the installed device. Recording can be done in several ways, such as scanning the pre-numbered and printed QR code on the device casing or manually affixing an identification card to the device casing. This easily completes the device binding and connection to the platform. This device is an integrated intelligent alarm device with a sophisticated design. Its functional modules are highly integrated and packaged, and it is also equipped with a solar charging panel on top, achieving green energy saving. In actual installation, it demonstrates extremely simple and quick operation, requiring only three steps to easily and quickly connect to the platform, greatly improving installation efficiency and ease of use.

[0030] This embodiment employs multi-source data measurement, specifically integrating a triaxial MEMS accelerometer, a dual-axis tilt sensor, and a temperature sensor, enabling simultaneous measurement of acceleration, tilt angle, and temperature monitoring indicators. This embodiment features a low-power design and on-site self-powering: a built-in lithium battery, combined with an integrated solar panel, continuously charges the lithium battery, ensuring 24 / 7 uninterrupted operation. The device in this embodiment adopts an integrated design, namely a data acquisition-transmission-power supply integrated structure, making installation convenient and ready to use immediately. The circuit board in this embodiment can pre-store threshold judgment programs written using existing technologies, thereby providing a three-level early warning mechanism with adjustable thresholds.

[0031] Under normal operating conditions, this embodiment can continuously sample and periodically upload data to a cloud server. Once the detected vibration acceleration or tilt angle exceeds a safety threshold, the device immediately triggers an alarm mechanism. The alarm mechanism can be a pre-set multi-level threshold, and the triggering of the thresholds can utilize existing program logic and computer technology. Different levels correspond to different situations; for example, for technicians, triggering a level one or two warning threshold means the bridge is at risk of collapse; while triggering a level three alarm threshold means the bridge is collapsing.

[0032] Therefore, this embodiment can achieve simultaneous and continuous measurement of vibration, tilt angle, and temperature, and can provide early warnings based on preset thresholds. Furthermore, it employs a low-power and wireless transmission design, combined with solar energy and a built-in lithium battery power supply, ensuring continuous and uninterrupted operation in harsh environments without electricity or internet access, thus demonstrating broad applicability.
