Description

Technical Field

[0001] This utility model belongs to the technical field of coastal engineering deformation monitoring technology, specifically relating to an unattended monitoring device for three-dimensional coastal deformation suitable for remote islands and reefs. Background Technology

[0002] Currently, the main technologies for monitoring the deformation of islands and reefs in the field of coastal engineering deformation monitoring technology include: manual surveying of coastal settlement and displacement, UAV photogrammetry, and GNSS base station monitoring.

[0003] The manual survey method for coastal settlement and displacement involves setting up deformation monitoring points at key locations along the coast of islands and reefs at specific intervals, and marking the locations of these settlement and displacement observation points with clear signs. Then, monitoring and management personnel regularly go to the site and use surveying equipment such as GPS and total stations to manually measure and record information on the vertical settlement, tilt, and other displacements of the coastline. Moreover, each measurement can only obtain the displacement of a single point, and repeated measurements are required to obtain displacement values ​​for different observation points.

[0004] Unmanned aerial vehicle (UAV) photogrammetry uses surveying UAVs to conduct large-area photogrammetry of island and reef coastlines. Then, by constructing a digital elevation model, the elevation of the island and reef coastline at different times can be obtained. Although this method can quickly obtain large-area coastal deformation data of islands and reefs, it still requires two or more operators to conduct on-site measurements under the guidance of a ground navigation and monitoring station. Therefore, it also requires personnel to go to the island multiple times to conduct measurements.

[0005] GNSS base station monitoring is a commonly used deformation monitoring method in nearshore marine engineering in recent years. It mainly involves setting up GNSS receivers on fixed poles at the engineering deformation monitoring points, directly powering the equipment with solar cells, and then transmitting the monitoring data back to researchers via a communication base station to achieve long-term continuous monitoring of coastal deformation. However, this method cannot be directly used on uninhabited islands and reefs in the open sea. Due to severe weather, the solar panel batteries often stop working due to high temperatures, and may even experience explosions or fires. Furthermore, because it relies solely on solar panels for power, the equipment may experience power outages during the monsoon season when there is no sunlight, leading to the loss of recorded data.

[0006] Therefore, it can be seen that traditional coastal deformation monitoring technologies require regular inspections by personnel, and the limited number of monitoring points and information results in high monitoring costs. Furthermore, limitations in power supply and storage modes make them unsuitable for the extreme environments of tropical islands and reefs in the open sea. In addition, the high dependence on on-site monitoring and maintenance leads to highly irregular monitoring cycles. Therefore, there is an urgent need for a multi-dimensional coastal deformation monitoring system that can adapt to the high-temperature and high-humidity environments of remote islands and reefs and does not require long-term personnel on-site monitoring.

[0011] Furthermore, the explosion-proof heat dissipation box is provided with several fireproof and heat-insulating layers, which divide the explosion-proof heat dissipation box into multiple layers.

[0013] Furthermore, there are multiple cooling fans, each of which is installed on each layer of the explosion-proof heat dissipation box.

[0052] During the use and installation of this utility model's unattended three-dimensional deformation monitoring equipment for remote islands and reefs:

[0053] In the actual monitoring process of remote islands and reefs, two coastal monitoring technicians are required for the initial installation of this utility model. The technicians should first fix the base of the explosion-proof heat sink 8 to the ground at the monitoring station location using bolts. If the soil at the monitoring station location is loose, cement can be used for reinforcement to ensure stability. After the explosion-proof heat sink 8 is fixed, the technicians install the first support rod 4 on its top. The support rod is secured to the top of the explosion-proof heat sink 8 with screws. After fixing, a waterproof rubber ring 7 is used to seal the interface. After the first support rod 4 is installed, the 3D laser scanner 3 is installed on its top, and the power cord and data transmission line of the 3D laser scanner 3 are passed through the first support rod 4, extending into the interior of the explosion-proof heat sink 8. When installing the 3D laser scanner 3, ensure that the bubble in the level on its base is centered to ensure the instrument is placed stably.

[0054] Next, technicians installed a second support rod 2 on top of the 3D laser instrument, and then installed a measurement-type GNSS receiver 1 on top of the second support rod 2. The receiver's power and data transmission lines were passed through the first support rod 4 and extended into the explosion-proof heat dissipation box 8. After the measurement-type GNSS receiver 1 was installed, technicians installed two solar panels at a 45-degree angle on top of the explosion-proof heat dissipation box 8, connecting them to the first support rod 4 using a fixing support rod 6. Simultaneously, the power lines of the solar panels were introduced into the explosion-proof heat dissipation box 8 through the first support rod 4. Technicians then opened the door of the explosion-proof heat dissipation box 8, placed three layers of fireproof padding, and arranged two batteries 16, a central control computer 12, and an integrated hard drive 11 on different levels. All equipment was secured to the fireproof partition 15 using cable ties.

[0055] Next, the technicians connected the solar panel 5 and four batteries 16 in parallel, and connected them using the power switching switch 14 to form the power supply system of this utility model. After the power supply is installed, the power cords of the measuring GNSS receiver 1, the 3D laser scanner 3, and the central control computer 12 need to be connected to the power supply system. The three cooling fans 10 should be connected in parallel to the automatic temperature control switch (which starts when the temperature exceeds 30 degrees Celsius) and connected to the power supply system. The technicians need to connect the data connection cables of the measuring GNSS receiver 1, the 3D laser scanner 3, and the hard disk array to the central control computer 12, and then set the sampling period of the GNSS receiver and the 3D laser scanner 3 on the central control computer 12 according to the actual monitoring needs, and set the data storage location to the hard disk array. In addition, the central control computer 12 needs to be set to one-button switch mode so that it can automatically control the monitoring and sampling of the GNSS receiver and the 3D laser scanner 3 after being turned on, and then connect it to the main power switch 13. After completing the above operations, the technicians need to test whether the connection between the main power switch 13 and the power switching switch 14 is normal, and use a multimeter to test the charging power of the solar panel 5. In addition, technicians need to use an external laptop to check whether the monitoring data is stored correctly in the hard drive array. After the check is completed, the technicians can close the door of the explosion-proof cooling box 8 and lock it if necessary.

[0056] During subsequent maintenance on the island, only the following four operations need to be performed: First, check the condition of the equipment, whether there is any damage or severe corrosion, and replace it if necessary; Second, clean the solar panels and 3D laser scanner 3; Third, check the solar power output and battery voltage 16 to ensure the health of the power supply system; Fourth, retrieve the stored hard drive data, or replace it with a new hard drive.

[0057] The embodiments of this utility model are not limited thereto. Based on the above content of this utility model, using ordinary technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, this utility model can also be modified, replaced or combined in various other forms, all of which fall within the scope of protection of this utility model.
