Description

Technical Field

[0001] This utility model relates to the field of rockfall monitoring technology, specifically to a rockfall monitoring and alarm device. Background Technology

[0002] Among current slope protection measures, flexible passive protection nets have seen rapid development and widespread adoption due to their inherent advantages such as simple construction, convenient maintenance, advanced technology, safety and reliability, environmental friendliness and economy, and standardized design and selection. They are used in many slope protection projects. The main structure of a flexible passive protection net consists of four main parts: a flexible metal interception net, an anchoring system (anchor bolts, anchor ropes, base, and support ropes), an energy dissipator, and support columns.

[0003] While flexible protective nets demonstrate unique advantages in providing physical barriers against external impacts, their protective mechanism is essentially limited to a relatively simple, passive form of protection, lacking monitoring and early warning capabilities. When a flexible protective net encounters a strong external impact, causing structural vibration and displacement, the absence of a built-in real-time monitoring system and early warning mechanism means that this anomaly cannot be detected and reported in a timely manner, thus delaying the opportunity to take emergency measures and greatly increasing potential safety risks and uncertainties. Utility Model Content

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] like Figures 1-2As shown, the rockfall monitoring and alarm device of this utility model includes a three-axis displacement vibration sensor, a data transmission module, a management platform, and a photography module.

[0024] The triaxial displacement vibration sensor is installed on the support column of the flexible protective net;

[0025] The triaxial displacement vibration sensor is electrically connected to the data transmission module;

[0026] The management platform communicates with the data transmission module, and the management platform connects to the camera module through the data transmission module.

[0027] Specifically, triaxial displacement vibration sensors are used to monitor minute displacements and vibrations in mountain rocks. The triaxial design means it can detect displacement and vibration from three directions (typically X, Y, and Z axes), providing more comprehensive monitoring data. The triaxial displacement vibration sensor uses the WTVB01-485, featuring high precision, triaxial angular velocity of 0–50 mm / s, triaxial acceleration of ±16G, vibration angular velocity of ±2000° / s, triaxial vibration angle of 0–180°, displacement sensing up to 0–30000 μm, triaxial vibration frequency of 1–100 Hz, and support for multiple protocols.

[0028] The data transmission module is responsible for transmitting the data collected by the sensors (such as displacement, vibration intensity, etc.) to the management platform.

[0029] The management platform is the core of the entire monitoring system. It receives data from the data transmission module and analyzes it. The management platform can display monitoring data in real time and determine whether there is a risk of rockfall based on preset thresholds or algorithms. Once an anomaly is detected, the management platform will trigger an alarm mechanism.

[0030] The camera module can capture images of the scene and transmit these images to the management platform for further confirmation and recording of rockfall events.

[0031] By combining a triaxial displacement vibration sensor, a data transmission module, a management platform, and a camera module, the triaxial displacement vibration sensor can detect the displacement and vibration of the flexible protective netting and transmit this monitoring data to the management platform via the data transmission module. This allows for an assessment of the severity of the vibration and triggers corresponding early warning mechanisms. In conjunction with the camera module, managers can gain a more intuitive understanding of the on-site situation.

[0032] In some embodiments, the data transmission module includes a 4G network communication card.

[0033] Specifically, the data transmission module is an industrial 4G network communication card. This product is based on the domestic version of A7670C and supports two internet access modes: PPP dial-up and driverless RNDIS. It is suitable for networking various industrial equipment and meets the wireless data networking needs of most IoT devices.

[0034] In some embodiments, the camera module includes a camera 7.

[0035] Specifically, the camera module uses an industrial-grade security camera 7, which supports a 120-degree shooting angle and 1080P high-definition photography. With an IR_CUT switcher, an 850 infrared light board, and a self-light sensor chip, it can achieve nighttime shooting. This product features low power consumption, small size, simple installation, and support for multiple systems.

[0036] In some embodiments, a power supply module is also included, which is connected to the triaxial displacement vibration sensor, the data transmission module and the imaging module respectively, and the power supply module includes a solar panel 4.

[0037] Specifically, the solar panel 4 can provide continuous power, improving the device's endurance.

[0038] The power supply module uses four solar panels (monocrystalline photovoltaic panels) with a photoelectric conversion efficiency of 23%, enabling continuous power generation even during continuous cloudy or rainy days. The battery module adopts a bidirectional electric loop control scheme with dual power supply, resulting in longer battery life. The wire connection interface uses a sealed connection to ensure dust and water resistance. Currently, purchasing a 50W high-power generator can effectively guarantee uninterrupted power supply for long-term use.

[0039] In some embodiments, the device also includes a box body 1, which is located on the support column of the flexible protective net. A sealing cover 2 is installed on the top of the box body 1, and a bracket 3 is symmetrically arranged on the top of the sealing cover 2. The bracket 3 is rotatably connected to the solar panel 4.

[0040] In some embodiments, the box body 1 has an opening at one end away from the sealing cover 2, a sealing glass 5 is installed on the box body 1 at the opening, a fixing bracket 6 is installed inside the box body 1, the middle part of the fixing bracket 6 is connected to the camera 7, and the fixing bracket 6 is located at the opening.

[0041] Specifically, the camera 7 can monitor the external situation through the opening, and the sealed glass 5 protects the camera 7.

[0042] In some embodiments, the number of openings, sealing glass 5, fixing brackets 6, and cameras 7 are all two, and they are arranged symmetrically.

[0043] Specifically, it can increase the field of view of camera 7.

[0044] In some embodiments, the system also includes a column 8, with a U-shaped locking block symmetrically arranged at the bottom end of the column 8. The locking block is installed on the support column of the flexible protective net and locked by a locking bolt. An adjustment frame 9 is installed at the top end of the column 8 and is connected to the box body 1.

[0045] In some embodiments, an LED display screen is also included, which is positioned in front of sections of the road prone to rockfalls. The LED display screen is connected to the management platform via a wireless data transmission module.

[0046] Specifically, when the management platform receives new alarm information, it can assess its urgency and update the content of the LED display screen accordingly to ensure the real-time nature and accuracy of the information.

[0047] The LED display screen uses Shenghao Electronics Technology's display screen, which displays two different situations for alarm reminders.
