Description

Technical Field

[0001] This invention relates to the field of earthquake monitoring technology, specifically to an earthquake measurement device that combines a high-frequency GPS antenna for deformation and displacement monitoring. Background Technology

[0002] As is well known, earthquake detection refers to the monitoring and detection of earthquake precursor anomalies and seismic activity before and after an earthquake occurs. In seismology, seismographs are used to measure the magnitude, time and location of ground shaking, etc. Earthquake prediction is made by studying the laws of seismic activity, such as seismic gaps, seismic strips and seismic correlations, or by using instruments to monitor abnormal changes in the earth's electric and magnetic fields to predict earthquakes.

[0003] Seismic measurement devices can be used in earthquake detection. The problem with existing technology is that the accuracy of traditional seismic measurement instruments, such as mechanical seismographs, is greatly affected by the friction, wear and tear of mechanical parts and gravity, making it difficult to achieve high-precision measurements. While electronic levels have improved measurement accuracy, they are also easily affected by changes in ambient temperature and air pressure.

[0004] Based on the problems mentioned above, we found that existing seismic detection equipment, when used alone, is unlikely to avoid these problems simultaneously. Therefore, we propose a seismic measurement device that uses the principle of laser interferometry to measure displacement with high accuracy, and can be combined with mechanical methods to reduce the probability of false alarms. In online mode, it can also be combined with high-frequency GPS antennas for deformation displacement monitoring for further seismic determination. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a seismic measurement device that combines a high-frequency GPS antenna for deformation displacement monitoring. It has the advantages of using the principle of laser interferometry to measure displacement with high accuracy, being able to combine mechanical methods to reduce the probability of false alarms, and being able to perform seismic detection in online mode by combining high-frequency GPS antennas for deformation displacement monitoring.

[0007] (II) Technical Solution

[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a seismic measurement device combining a high-frequency GPS antenna for deformation displacement monitoring, comprising two transmitter racks and two receiver racks, wherein the bottom of the transmitter rack is fixedly connected to a support leg, the top of the transmitter rack is fixedly connected to a transmitting component, and the top of the receiver rack is fixedly connected to a receiving component.

[0009] The launch assembly includes a tray, a narrow frame fixedly connected to the top of the tray, a transmitter mounted on the top of the narrow frame, a connecting frame fixedly connected to the top of the tray, a top frame fixedly connected to the top of the connecting frame, a chassis and a GPS antenna fixedly connected to the top of the top frame, and a protective plate installed between the connecting frames.

[0010] The receiving assembly includes an adjustment plate, a connecting spring fixedly connected to the top of the adjustment plate, a carrier plate fixedly connected to the top of the connecting spring, a receiving end fixedly connected to the top of the carrier plate, a protective cover installed on the top of the carrier plate, a support airbag fixedly connected to the top of the adjustment plate, the top of the support airbag contacting the carrier plate, and a lifting screw threadedly connected to the inner side of the adjustment plate, the top of the lifting screw contacting the bottom of the carrier plate.

[0011] Using the above technical solution, two sets of measuring equipment are mounted by setting up two transmitter racks and two receiver racks. During use, the transmitter racks are installed at the measuring positions using support legs. A tray is provided for mounting the transmitter, which is protected by a protective plate and a top frame. The emitted laser beam passes through the transparent protective plate. The receiver rack is positioned slightly away from the transmitter racks, and a carrier plate connected by an adjusting plate and a connecting spring is used to mount the receiver. The receiver is protected by a protective cover and supported by a support airbag auxiliary structure. The receiver receives the laser beam signal. In cases of uneven terrain or elevation differences, the bottom of the carrier plate can be pressed down by rotating the lifting screws at different positions, causing it to tilt. This causes deformation of the connecting spring and the support airbag, and the receiver… The system receives laser optical signals. The transmitting and receiving ends of two transmitters and two receivers form perpendicularly intersecting measurement baselines. These two sets of vertical baselines construct a two-dimensional displacement coordinate system. The laser beam forms a round-trip optical path between the columns. The change in baseline length caused by the earthquake is calculated by the movement of interference fringes. By monitoring the displacement data of the two sets of baselines in real time, the horizontal component of the seismic wave can be determined. A GPS antenna located on the top of the frame acquires the approximate location information of the measurement point in real time, providing initial alignment and positioning reference for the laser measurement system. By receiving signals from multiple satellites, the system accurately calculates its own three-dimensional coordinates using carrier phase differential technology. Before an earthquake occurs, the accumulation of crustal stress causes the plates to move slowly, resulting in slight changes in the location of the monitoring point. The GPS antenna collects these changes to detect the earthquake.

[0012] The invention is further configured such that: the transmitting end is a helium-neon laser equipped with a collimating lens; a GPS receiver, a data acquisition and processing unit, and a communication module are installed inside the chassis; the protective plate and the protective cover are both made of plexiglass material; and the receiving end is an avalanche photodiode array.

[0013] Using the above technical solution, a helium-neon laser is set up to maintain stable beam transmission. The avalanche photodiode array, as the receiving end, can effectively receive the beam and detect small displacement changes. The GPS receiver, data acquisition and processing unit, and communication module are protected by being installed inside the chassis. The data acquisition and processing unit is responsible for collecting data from the laser measurement system and the GPS receiver, and performing preprocessing, such as filtering, amplification, and analog-to-digital conversion, for subsequent fusion processing and analysis. The communication module can remotely transmit data to the monitoring center or other equipment when online.

[0014] The present invention is further configured such that: a transparent cylinder is fixedly connected to the bottom of the launcher; an angle sensor and a locator are provided at the top of the inner wall of the transparent cylinder; the angle sensor and the locator are electrically connected; a metal wire is fixedly connected to the input end of the locator; and a counterweight is fixedly connected to the bottom of the metal wire.

[0015] Using the above technical solution, a transparent cylinder is set up as the installation and protection position of the structure, and an angle sensor is set up in conjunction with a locator to install the counterweight of the metal wire. When an earthquake occurs, the ground acceleration will cause the counterweight to swing. The swing angle of the pendulum is proportional to the ground acceleration, and the locator and angle sensor record the swing as a judgment benchmark.

[0016] The invention is further configured such that: the metal wire is made of a high-strength, low-damping material; a vertical frame is fixedly connected to the top of the inner wall of the transparent cylinder; and the angle sensor and the positioner are installed on the inner side of the vertical frame.

[0017] By adopting the above technical solution, a vertical frame is set up to suspend the angle sensor and the positioner, and to provide the required height and space for the displacement of the counterweight.

[0018] The present invention is further configured such that: an upper frame is bolted to the outer side of the receiving frame, a photovoltaic panel is rotatably connected to the outer side of the upper frame, a sliding sleeve is slidably connected to the outer side of the receiving frame, an adjusting strip is rotatably connected to the outer side of the sliding sleeve, and the top of the adjusting strip is rotatably connected to the photovoltaic panel.

[0019] By adopting the above technical solution, an upper frame with adjustment strips and sliding sleeves is set to adjust the angle of the photovoltaic panel outside the receiving frame. When the light is good, it can slide down, so that the photovoltaic panel can be pushed along the upper frame by the adjustment strips to facilitate the generation of electricity through natural light as an auxiliary function of the structure.

[0020] The present invention is further configured such that: two side plates are bolted to the outer side of the receiving frame, a limiting rod is fixedly connected between the top side plate and the bottom side plate, the outer side of the limiting rod is slidably connected to the sliding sleeve, and a fastening screw is threadedly connected to the inner side of the sliding sleeve, and the fastening screw is in close contact with the receiving frame on the side near the receiving frame.

[0021] By adopting the above technical solution, the sliding of the sleeve can be limited by setting a side plate and a limiting rod, and the rotation of the sleeve can be prevented. The fastening screw can be tightened when the sleeve slides to the required position to fix the position of the structure.

[0022] The present invention is further configured such that: the bottom of the receiving frame is provided with an external thread, the bottom of the receiving frame is rotatably connected to a placement frame, and the bottom of the placement frame is rotatably connected to a placement leg.

[0023] By adopting the above technical solution, a placement frame and placement legs are set up to securely place the receiving frame in the installation position, and the placement legs can rotate along the placement frame to allow for structural adjustment.

[0024] The present invention is further configured such that: a height frame is rotatably connected to the top of the placement leg, and an adjustment block is rotatably connected to the top of the height frame.

[0025] By adopting the above technical solution, by setting up a height frame in conjunction with an adjustment block, when it is necessary to adjust the height of the receiving frame, the height frame can be pushed and pulled by vertically moving the adjustment block, so as to control the synchronous opening and closing of multiple placement legs and thus adjust the height of the receiving frame.

[0026] The invention is further configured such that: the adjusting block is threadedly connected to the outside of the receiving frame, and a bottom pad is fixedly connected to the bottom of the placement leg.

[0027] Using the above technical solution, when the receiving frame is rotated along the placement frame, the adjusting block connected to it by threads will not rotate due to the contact limitation between the placement leg and the ground, but will rise and fall vertically to adjust the placement leg. The set base pad can more stably place or install the receiving frame.

[0028] The present invention is further configured such that: the photovoltaic panel is externally connected to a storage battery, an inverter, and a controller.

[0029] By adopting the above technical solution, an external battery, inverter and controller are set up to control the operation of the photovoltaic panels and store the electricity for later use.

[0030] (III) Beneficial Effects

[0031] Compared with the prior art, the present invention provides a seismic measurement device that combines a high-frequency GPS antenna for deformation displacement monitoring, which has the following beneficial effects:

[0032] This seismic measurement device, combining a high-frequency GPS antenna for deformation displacement monitoring, uses two transmitter racks and two receiver racks to support two sets of measuring equipment. During operation, the transmitter racks are mounted at the measurement position using support legs. A tray is provided for mounting the transmitter, which is protected by a protective plate and a top frame. The emitted laser beam passes through the transparent protective plate. The receiver rack is positioned slightly away from the transmitter racks, and a carrier plate connected by an adjustment plate and connecting springs is used to mount the receiver. The receiver is protected by a protective cover and supported by an airbag auxiliary structure. The receiver receives the laser beam signal. In cases of uneven terrain or elevation differences, the bottom of the carrier plate can be tilted by rotating the lifting screws at different positions. This causes the connecting springs and supporting airbags to engage. The laser beam undergoes deformation, and the receiving end receives the laser optical path signal. The transmitting and receiving ends of the two transmitting and receiving frames form perpendicularly intersecting measurement baselines. The two sets of vertical baselines construct a two-dimensional displacement coordinate system. The laser beam forms a round-trip optical path between the columns. The change in baseline length caused by the earthquake is calculated by the movement of interference fringes. By monitoring the displacement data of the two sets of baselines in real time, the horizontal component of the seismic wave can be determined. The GPS antenna set on the top of the frame obtains the approximate location information of the measurement point in real time, providing initial alignment and positioning reference for the laser measurement system. By receiving signals from multiple satellites, the system accurately calculates its own three-dimensional coordinates using carrier phase difference technology. Before an earthquake occurs, the accumulation of crustal stress causes the plates to move slowly, resulting in slight changes in the location of the monitoring point. The GPS antenna collects these changes to detect the earthquake. Attached Figure Description

Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please see Figure 1-6 A seismic measurement device combining a high-frequency GPS antenna for deformation displacement monitoring includes two transmitter racks 1 and two receiver racks 2. The bottom of the transmitter rack 1 is fixedly connected to a support leg 3, the top of the transmitter rack 1 is fixedly connected to a transmitter assembly 4, and the top of the receiver rack 2 is fixedly connected to a receiver assembly 5.

[0044] The transmitting assembly 4 includes a tray 41, a narrow frame 48 fixedly connected to the top of the tray 41, a transmitter 42 mounted on the top of the narrow frame 48, a connecting frame 43 fixedly connected to the top of the tray 41, a top frame 44 fixedly connected to the top of the connecting frame 43, a housing 45 and a GPS antenna 46 fixedly connected to the top of the top frame 44, and a protective plate 47 installed between the connecting frames 43.

[0045] The receiving component 5 includes an adjustment plate 51, a connecting spring 52 fixedly connected to the top of the adjustment plate 51, a carrier plate 53 fixedly connected to the top of the connecting spring 52, a receiving end 54 fixedly connected to the top of the carrier plate 53, a protective cover 55 installed on the top of the carrier plate 53, a support airbag 56 fixedly connected to the top of the adjustment plate 51, the top of the support airbag 56 contacting the carrier plate 53, and a lifting screw 57 threadedly connected to the inner side of the adjustment plate 51, the top of the lifting screw 57 contacting the bottom of the carrier plate 53.

[0046] Two sets of measuring equipment are set up by setting up two transmitter racks 1 and two receiver racks 2. During use, the transmitter rack 1 can be installed at the measuring position by the support legs 3. The set tray 41 is used to install the transmitter end 42. The transmitter end 42 is protected by the protective plate 47 and the top frame 44, and the emitted laser beam passes through the transparent protective plate 47. The receiver rack 2 is set at a position slightly away from the transmitter rack 1. The carrier plate 53 connected by the adjusting plate 51 and the connecting tension spring 52 is used to install the receiver end 54. The receiver end 54 is protected by the protective cover 55, and the supporting airbag 56 is used for auxiliary support. At this time, the receiver end 54 receives the laser beam signal. When the terrain is uneven or there is a height difference, the bottom of the carrier plate 53 can be pressed against by rotating the lifting screws 57 at different positions, so that it tilts. At this time, the connecting tension spring 52 and the supporting airbag 56 are connected. Deformation occurs at point 6, and receiver 54 receives the laser optical path signal. The transmitters 42 and receivers 54 of the two transmitters 1 and the two receivers 2 form a vertically intersecting measurement baseline. The two sets of vertical baselines construct a two-dimensional displacement coordinate system. The laser beam forms a round-trip optical path between the columns. The change in baseline length caused by the earthquake is calculated by the movement of the interference fringes. By monitoring the displacement data of the two sets of baselines in real time, the horizontal component of the seismic wave can be determined. The GPS antenna 46, located on the top of the top frame 44, obtains the approximate location information of the measurement point in real time, providing initial alignment and positioning reference for the laser measurement system. By receiving signals from multiple satellites, the system accurately calculates its own three-dimensional coordinates using carrier phase difference technology. Before an earthquake occurs, the accumulation of crustal stress causes the plates to move slowly, resulting in slight changes in the location of the monitoring point. The GPS antenna collects these changes to detect the earthquake.

[0047] The transmitter 42 is a helium-neon laser equipped with a collimating lens. The inside of the chassis 45 houses a GPS receiver, a data acquisition and processing unit, and a communication module. The protective plate 47 and the protective cover 55 are both made of plexiglass. The receiver 54 is an avalanche photodiode array. By setting up the helium-neon laser to maintain stable beam transmission, the avalanche photodiode array as the receiver 54 can effectively receive the beam and detect small displacement changes. The GPS receiver, data acquisition and processing unit, and communication module are protected inside the chassis 45. The data acquisition and processing unit is responsible for acquiring data from the laser measurement system and the GPS receiver, and performing preprocessing such as filtering, amplification, and analog-to-digital conversion for subsequent fusion processing and analysis. The communication module can remotely transmit data to the monitoring center or other equipment when online.

[0048] The working principle of this embodiment is as follows: The transmitter 1 is fixed at the measurement position by the support legs 3 at the bottom of the transmitter 1. At a slightly away location from the transmitter 1, the receiver 2 is installed securely by adjusting the height using the placement bracket 19, placement legs 20, and other structures at the bottom of the receiver 2, along with the adjustment block 22. If the terrain of the measurement site is uneven or there is a height difference, the lifting screw 57 inside the adjustment plate 51 in the receiver assembly 5 is rotated to press against the bottom of the loading plate 53, causing it to tilt. The connecting spring 52 and the support airbag 56 deform accordingly, ensuring that the receiver 54 can accurately receive the laser light path signal emitted by the transmitter 42. This allows the transmitters 42 and receivers 54 of the two transmitters 1 and the two receivers 2 to form a vertically intersecting measurement baseline, creating a two-dimensional displacement coordinate system. The transmitter 42 emits a stable laser beam, and the receiver 54 receives the laser signal, detecting minute displacement changes. The data acquisition and processing unit inside the chassis 45 collects data from the laser measurement system and GPS. The receiver outputs data and performs preprocessing such as filtering, amplification, and analog-to-digital conversion. In online mode, the communication module remotely transmits the preprocessed data to the monitoring center or other equipment. Utilizing the principle of laser interferometry, the displacement of two sets of baseline displacement data monitored in real time is calculated based on the movement of interference fringes caused by the change in baseline length due to earthquakes, thus determining the horizontal component of the seismic wave. Simultaneously, the GPS antenna receives signals from multiple satellites and uses carrier phase differential technology to accurately calculate its own three-dimensional coordinates, analyze the minute positional changes in the Earth's crust caused by stress accumulation, and realize earthquake detection.

[0049] Example 2

[0050] refer to Figure 1-7 An earthquake measurement device combining a high-frequency GPS antenna for deformation displacement monitoring also includes a transparent cylinder 6 fixedly connected to the bottom of the transmitter 1. An angle sensor 7 and a locator 8 are provided on the top of the inner wall of the transparent cylinder 6. The angle sensor 7 and the locator 8 are electrically connected. A metal wire 9 is fixedly connected to the input end of the locator 8. A counterweight 10 is fixedly connected to the bottom of the metal wire 9. The transparent cylinder 6 is set as the installation and protection position of the structure. The angle sensor 7 and the locator 8 are used to install the counterweight 10 of the metal wire 9. When an earthquake occurs, the ground acceleration will cause the counterweight 10 to swing. The swing angle of the pendulum is proportional to the ground acceleration. The locator 8 and the angle sensor 7 record the swing as a judgment benchmark.

[0051] The metal wire 9 is made of high-strength, low-damping material. A vertical frame 11 is fixedly connected to the top of the inner wall of the transparent cylinder 6. Angle sensor 7 and positioner 8 are installed inside the vertical frame 11. The vertical frame 11 is used to suspend the angle sensor 7 and positioner 8 and to provide the necessary height and space for the displacement of the counterweight 10. An upper frame 12 is bolted to the outside of the receiving frame 2. A photovoltaic panel 13 is rotatably connected to the outside of the upper frame 12. A sliding sleeve 14 is slidably connected to the outside of the receiving frame 2. An adjusting strip 15 is rotatably connected to the outside of the sliding sleeve 14. The top of the adjusting strip 15 is rotatably connected to the photovoltaic panel 13. By setting the upper frame 12 in conjunction with the adjusting strip 15 and the sliding sleeve 14, the position of the photovoltaic panel 13 in the receiving frame is adjusted. The external angle of the receiving frame 2 allows it to slide down in good lighting conditions, enabling the photovoltaic panel 13 to unfold along the upper frame 12 via the adjusting strip 15. This facilitates the generation of electricity through natural light, serving as an auxiliary function of the structure. Two side plates 16 are bolted to the outside of the receiving frame 2. A limit rod 17 is fixedly connected between the top and bottom side plates 16. The outer side of the limit rod 17 is slidably connected to the sliding sleeve 14. A fastening screw 18 is threaded onto the inner side of the sliding sleeve 14. The fastening screw 18 is in close contact with the receiving frame 2 on the side closest to it. By setting the side plates 16 in conjunction with the limit rod 17, the sliding of the sliding sleeve 14 can be limited, preventing it from rotating. The fastening screw 18 is set to ensure that the sliding sleeve 14 slides to the desired position. The fastening screw 18 can be tightened to fix the position of the structure. The bottom of the receiving frame 2 has an external thread, and a placement frame 19 is rotatably connected to the bottom of the receiving frame 2. A placement leg 20 is rotatably connected to the bottom of the placement frame 19. By setting the placement frame 19 and placement leg 20 together, the receiving frame 2 is securely placed in the installation position. The placement leg 20 can rotate along the placement frame 19, allowing for structural adjustment. A height frame 21 is rotatably connected to the top of the placement leg 20, and an adjustment block 22 is rotatably connected to the top of the height frame 21. By setting the height frame 21 and adjustment block 22 together, when the height of the receiving frame 2 needs to be adjusted, the height frame 21 can be pushed or pulled by vertically moving the adjustment block 22. The synchronous opening and closing of multiple placement legs 20 is controlled to adjust the height of the receiving frame 2. The adjusting block 22 is threadedly connected to the outside of the receiving frame 2. The bottom of the placement leg 20 is fixedly connected to the bottom pad 23. When the receiving frame 2 is rotated along the placement frame 19, the adjusting block 22 threadedly connected to it will not rotate due to the contact limitation between the placement leg 20 and the ground, but will rise and fall vertically to adjust the placement leg 20. The bottom pad 23 can more stably place or install the receiving frame 2. The photovoltaic panel 13 is externally connected to a battery, inverter and controller. The external battery, inverter and controller are used to control the operation of the photovoltaic panel 13 and to store electricity for later use.

[0052] The working principle of this embodiment is as follows: When an earthquake occurs, the ground acceleration causes the counterweight 10 inside the transparent cylinder 6 at the bottom of the transmitter 1 to swing. The high-strength, low-damping metal wire 9 drives the counterweight 10 to move. The angle sensor 7 and the positioner 8 record the swing angle and position data in real time, providing a mechanical measurement benchmark for earthquake judgment. When the light is good, the sliding sleeve 14 on the outside of the sliding receiver 2 pushes the photovoltaic panel 13 along the upper frame 12 to rotate to a suitable angle through the adjustment bar 15, converting solar energy into electrical energy. This energy is stored and regulated by an external battery, inverter, and controller to power the auxiliary functions of the equipment. According to the actual measurement requirements, the adjustment block 22 on the outside of the receiver 2 is rotated, which drives the height frame 21 to push and pull the placement leg 20 to open and close synchronously, realizing the height adjustment of the receiver 2. At the same time, after the angle of the photovoltaic panel 13 is adjusted to the correct position, the fastening screw 18 is tightened to make it in close contact with the receiver 2, fixing the position of the sliding sleeve 14, ensuring stable power generation of the photovoltaic panel 13 and overall equipment stability.
