Description

Technical Field

[0001] This invention belongs to the field of geological monitoring technology, specifically a geological disaster monitoring and early warning device. Background Technology

[0002] In existing technologies, geological disaster monitoring mostly employs single-parameter monitoring equipment, such as Global Navigation Satellite Systems (GNSS), Synthetic Aperture Radar Interferometry (INSAR), distributed fiber optic sensing systems, total stations, and photogrammetric systems. These single devices can only monitor a specific parameter, making it difficult to comprehensively reflect the potential risks of geological disasters. Furthermore, traditional monitoring equipment generally suffers from low data processing efficiency, large transmission delays, insufficient monitoring accuracy, and limited automation, making it difficult to meet the demands for real-time monitoring and efficient early warning in complex geological environments. Although some multi-parameter monitoring devices have emerged in recent years, significant technical bottlenecks remain in areas such as data accuracy, real-time response, adaptability to complex environments, and reliability of intelligent early warning systems.

[0003] Taking GNSS technology, widely used in surface displacement monitoring, as an example, it is based on satellite positioning principles. Multiple devices conduct long-term synchronous observations at fixed observation points, using differential calculation techniques to eliminate systematic deviations such as satellite orbital errors and clock biases. Combined with precise ephemeris data, the absolute coordinates of the monitoring points are calculated. Finally, by comparing the static calculation results at different time periods, precise measurement of the horizontal and vertical displacement changes of the monitoring points is achieved. This technology, with its advantages of high precision, all-weather operation, automation, and the ability to interface with global benchmark networks, has become a primary means of long-term surface displacement monitoring.

[0004] However, GNSS technology still has significant shortcomings in practical applications: First, the data processing requires complex error elimination and coordinate calculation procedures, resulting in a significant time lag, making it difficult to meet the stringent timeliness requirements of real-time geological disaster early warning. Second, monitoring accuracy is constrained by multiple factors, including the positioning accuracy of the reference station, the stability of data communication, interference from the observation environment (such as multipath effects), the geometric distribution of the satellite constellation, and data processing algorithms. Especially under severe weather conditions such as heavy rain and lightning, ionospheric disturbances intensify, and multipath effects are significantly amplified, leading to a substantial decrease in monitoring accuracy. Such extreme weather events are often accompanied by a high risk of geological disasters, easily causing false alarms or missed reports.

[0005] To improve the accuracy of GNSS data processing, existing technologies typically employ data filtering algorithms or extend the processing time window. However, these improvements inevitably sacrifice data real-time performance and accuracy, failing to simultaneously meet the dual requirements of timeliness and reliability in geological disaster monitoring. Furthermore, other traditional monitoring technologies (such as INSAR's susceptibility to terrain phase incoherence and the insufficient adaptability of distributed fiber optic sensing to complex terrain) also have their own limitations, making it difficult to achieve comprehensive, accurate, and real-time monitoring of multiple geological disaster parameters.

[0006] In summary, existing geological disaster monitoring technologies have shortcomings in terms of multi-parameter collaborative monitoring, real-time performance, accuracy, and environmental adaptability. There is an urgent need to develop a new geological disaster monitoring system to overcome these technical deficiencies and meet the actual needs of geological disaster monitoring and early warning.

[0007] Therefore, the present invention provides a geological disaster monitoring and early warning device. Summary of the Invention

Detailed Implementation

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0042] Example 1: As Figures 1 to 4 As shown in the figure, a geological disaster monitoring and early warning device according to an embodiment of the present invention includes an operational platform 1 and a multi-parameter monitoring platform 2;

[0043] The multi-parameter monitoring platform 2 includes a monitoring station 3 and a reference station 4;

[0044] The monitoring station 3 is equipped with a transmission module 10, a centralized control and monitoring hub 11, an early warning module 12, a GNSS 13, a gyroscope 14, an accelerometer 15, a laser displacement sensor 16, an earth pressure gauge 17, a soil temperature and humidity meter 18, a rain gauge 19, and a camera 20.

[0045] The transmission module 10 consists of a site data transmission unit 21, a mobile communication wireless transmission unit 22, and a Beidou short message unit 23.

[0046] The base station 4 is equipped with a laser target module 24 and a station data transmission unit 25;

[0047] The business platform 1 and the multi-parameter monitoring platform 2 exchange data through the transmission module 10; the monitoring station 3 and the base station 4 exchange data through the site data transmission unit 1 21 and the site data transmission unit 25.

[0048] The laser target module 24 consists of a highly reflective material 26 and a photoelectric sensor array 27.

[0049] Both the monitoring station 3 and the base station 4 are equipped with a power generation device 28, a charging and discharging module 29, and a battery 30 to provide power for the operation of the stations; the power generation device 28 can be a single or combined form of photovoltaic power generation, wind power generation, and grid power supply.

[0050] GNSS13 is used to monitor and acquire long-term displacement data of the installation point; gyroscope 14 and accelerometer 15 are used to measure the vibration and tilt of the site, and calculate short-term dynamic displacement through integration; earth pressure gauge 17 is used to monitor the changes in internal stress of the soil in real time and sense the fluctuations in earth pressure in areas such as slopes and foundation pits; soil temperature and humidity are used to monitor changes in soil moisture content and temperature; rain gauge 19 is used to measure rainfall; camera 20 is used to capture on-site images, and can capture images when monitoring trigger conditions are met, or can be remotely controlled to capture images.

[0051] The soil pressure gauge 17, soil temperature and humidity gauge 19 are used in conjunction to comprehensively capture early signs of disasters and simultaneously reflect the disaster evolution chain of "load change - environmental weakening - precipitation triggering".

[0052] The laser displacement sensor 16 is used in combination with the laser target module 24. The laser displacement sensor 16 is installed on the monitoring station 3, and the laser target module 24 is installed on the reference station 4. The reference station 4 has a stable observation environment and a reliable foundation. The laser displacement sensor 16 hits the laser target of the reference station 4 with a laser beam. The highly reflective material 26 of the laser target can reflect most of the laser back along the original path. The distance between the monitoring station 3 and the reference station 4 can be calculated by the transmission time difference. The photoelectric sensor array 27 on the laser target can provide feedback on the coordinate position of the laser irradiation.

[0053] By fusing the data from the gyroscope 14, accelerometer 15, laser displacement sensor 16, and laser target module 24, the coordinate displacement change of monitoring station 3 can be calculated through coordinate transformation. This method has strong real-time performance, which can make up for the lag problem of GNSS13 monitoring data and optimize the large fluctuations caused by the monitoring accuracy of GNSS13, thus avoiding false alarms or missed alarms.

[0054] The function of the centralized control and monitoring hub 11 is as follows:

[0055] Data processing and control: acquiring parameter data from GNSS13, gyroscope14, accelerometer15, laser displacement sensor16, earth pressure gauge17, soil temperature and humidity meter18, rain gauge19, camera20, and laser target module24;

[0056] Coordinate and manage the collaborative work of various sensors, including GNSS13, gyroscope14, accelerometer15, laser displacement sensor16, earth pressure gauge17, soil temperature and humidity meter18, rain gauge19, camera20, and laser target module24.

[0057] Data storage and transmission: The system stores data collected by GNSS13, gyroscope14, accelerometer15, laser displacement sensor16, earth pressure gauge17, soil temperature and humidity meter18, rain gauge19, camera20, and laser target module24. The data is then uploaded to the business platform 1 via transmission module 10. When data transmission by transmission module 10 is interrupted, the centralized control and monitoring hub 11 will communicate with the surrounding monitoring stations 3 via transmission module 10. Data communication uses LoRa communication, and the data is then uploaded to the business platform 1 via the surrounding monitoring stations 3.

[0058] Power and power consumption management manages the power supply of GNSS13, gyroscope14, accelerometer15, laser displacement sensor16, earth pressure gauge17, soil temperature and humidity meter18, rain gauge19, camera20, laser target module24, early warning module12, and transmission module10, optimizes power consumption, and ensures stable operation of the equipment in different scenarios.

[0059] Edge computing is enabled when all monitoring stations 3 transmission modules 10 are unable to interact with the business platform 1. The edge computing of the centralized control monitoring hub 11 is activated to process the data. When the warning conditions are met, the disaster warning will be broadcast through the warning module 12 and the warning information and calculation results will be sent through the Beidou short message unit 23. Edge computing is enabled when the site has no network, which facilitates power consumption management.

[0060] Example 2: Figures 5 to 10 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the early warning module 12 is composed of an audible and visual early warning device, a wireless transmission early warning unit, and an active safety early warning device;

[0061] The active safety early warning device includes a protective base 121 and a canopy 122. A rain gauge 19 is installed on the surface of the canopy 122. The monitoring station 3 is fixedly installed inside the protective base 121. The canopy 122 is fixedly installed on the upper side of the monitoring station 3. The protective base 121 can be directly installed on the ground, or it can be kept at a certain distance from the ground, or it can be placed in a shallow pit.

[0062] The monitoring station 3 and the bottom of the protective base 121 are both provided with a storage groove 123; the storage groove 123 is slidably connected to the mounting plate 124; the soil pressure gauge 17 and the soil temperature and humidity gauge 18 are fixedly installed on the lower side of the mounting plate 124; an electric telescopic rod 125 is fixedly installed between the upper side of the mounting plate 124 and the storage groove 123.

[0063] The protective base 121 provides an installation point for the monitoring station 3. The canopy 122 and the protective base 121 work together to protect the monitoring station 3, provide shade and rain protection, and at the same time, do not completely cover the monitoring station 3 to facilitate heat dissipation. Under normal circumstances, the electric telescopic rod 125 is in the extended state, and the soil pressure gauge 17 and the soil temperature and humidity meter 18 are inserted into the soil. When the warning conditions are met, the central control monitoring hub 11 controls the electric telescopic rod 125 to shorten and drive the mounting plate 124 to move upward, thereby putting the soil pressure gauge 17 and the soil temperature and humidity meter 18 into the storage tank 123 to prevent damage to the soil pressure gauge 17 and the soil temperature and humidity meter 18 in the event of a geological disaster.

[0064] The bottom of the protective base 121 is provided with a slot 126 at the corresponding position of the storage groove 123; a pair of trigger plates 127 are slidably connected inside the slot 126; a compression spring 128 is fixedly connected between the trigger plates 127 and the slot 126; an elastic pad 129 is fixedly connected to the side of the trigger plates 127 that are close to each other; a pair of baffles 130 are fixedly connected to the lower side of the mounting plate 124.

[0065] Under normal circumstances, a pair of baffles 130 can respectively block the trigger plates 127 on both sides to store the trigger plates 127 inside the slot 126. The compression spring 128 is in an energy storage state. When the mounting plate 124 moves upward, it can drive the baffles 130 to move upward synchronously, thereby releasing the trigger plates 127. The compression spring 128 pushes the pair of trigger plates 127 closer to each other and closes the storage slot 123, preventing various gravel, soil and other objects from entering the storage slot 123 and squeezing the soil pressure gauge 17 and the soil temperature and humidity gauge 18 during geological disasters.

[0066] The protective base 121 has a storage cavity 131 inside its side wall; a movable frame 132 is slidably connected inside the storage cavity 131; a set of support sleeves 133 are evenly distributed inside the storage cavity 131; a support rod 134 is slidably and sealed inside the support sleeve 133, and the upper end of the support rod 134 is fixedly connected to the movable frame 132; the mounting plate 124 and the storage groove 123 are slidably and sealed together; the bottom of the support sleeve 133 and the storage groove 123 are interconnected through a conduit 135.

[0067] Under normal circumstances, the movable frame 132 is completely inside the storage cavity 131 of the protective seat 121, so that the upper part of the monitoring station 3 is in contact with the atmosphere and maintains normal heat dissipation function. When the mounting plate 124 moves upward, it can squeeze the air inside the storage groove 123 and squeeze it into each support sleeve 133 through the conduit 135, drive the support rod 134 to extend upward and drive the movable frame 132 to rise until the movable frame 132 contacts the roof 122. At this time, the roof 122, the protective seat 121, and the movable frame 132 form a square box structure and completely cover the monitoring station 3, further protecting the monitoring station 3 and preventing the monitoring station 3 from being damaged by impact.

[0068] A corresponding groove 136 is provided on the lower side of the canopy 122 above the movable frame 132; a sealing membrane 137 is fixedly connected inside the corresponding groove 136; a quick-drying filler adhesive is provided between the upper side of the sealing membrane 137 and the corresponding groove 136; a set of sharp top blocks 138 are evenly distributed on the upper side of the movable frame 132.

[0069] When the movable frame 132 rises, it enters the corresponding groove 136 of the roof 122, and then the top block 138 can puncture the sealing membrane 137. Subsequently, the quick-drying filler on the upper side of the sealing membrane 137 flows out spontaneously downwards and flows to the gap between the movable frame 132 and the roof 122. On the one hand, it fills and seals the gap to prevent water from seeping into the monitoring station 3 during subsequent geological movements and causing the instruments to be soaked. On the other hand, it can also bond the movable frame 132 and the roof 122 together, providing a reinforcement effect.

[0070] A connecting groove 139 is provided at the top of the corresponding groove 136; a stop block 140 is fixedly connected to the bottom of the connecting groove 139; a pair of locking grooves 141 are provided at the top of the top block 138; a locking piece 142 is rotatably connected inside the locking groove 141; an elastic element 143 is fixedly connected between the locking piece 142 and the locking groove 141.

[0071] After the top of the top block 138 punctures the sealing membrane 137, it enters the connecting groove 139. During the entry process, the locking piece 142 is blocked by the stop block 140 and retracts into the locking groove 141. After the locking piece 142 completely passes the stop block 140, the elastic element 143 pushes the locking piece 142 to open to both sides. At this time, the locking piece 142 is supported on the upper side of the stop block 140, so that the top block 138 cannot move downward. Thus, the locking piece 142 and the stop block 140 lock and engage the top block 138 with the canopy 122, further enhancing the fixation between the canopy 122 and the movable frame 132, improving the overall structural strength, and preventing structural separation during violent shaking, bumping, and overturning.

[0072] A set of retaining pieces 144 are evenly distributed at the bottom of the top block 138. After the top block 138 punctures the sealing membrane 137, the retaining pieces 144 at its bottom can tear and support the sealing membrane 137, thereby further enlarging the opening of the sealing membrane 137 and improving the efficiency of the quick-drying filler flowing downward.

[0073] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
