Description

Technical Field

[0001] The present application relates to the technical field of slope monitoring, and in particular to a remote slope monitoring system. Background Art

[0002] Slope is a common engineering form in geotechnical engineering construction. High slope is the main engineering carrier in engineering construction. High slope is often located in areas with complex geological conditions. The stability of high slope plays a vital role in ensuring the safety of engineering construction. Therefore, it is particularly important to monitor the stability of high slope. By monitoring high slope and evaluating the feedback of early warning information, it is conducive to ensuring the long-term stability of high slope, which is of great significance to ensuring the safety of engineering and personal and property.

[0003] Since the 1990s, slope monitoring research has entered a new stage of automated monitoring and early warning, quantitative analysis and evaluation. With the rapid development of computer, electronic, measurement, communication and other technologies, a number of new detection technologies have emerged, such as "3S" technology (RS, GPS and GNSS), three-dimensional laser scanning technology, synthetic aperture radar interferometry measurement technology, time domain reflection technology, etc.

[0004] However, traditional GNSS technology is limited by satellite clock errors, communication delays, receiver errors and data processing errors. The single-point positioning accuracy of a single system or a combination of multiple systems is low, resulting in inaccurate monitoring systems.

[0005] At the same time, the cold environment further reduces the accuracy of the monitoring system. Specifically, the remote slope monitoring system includes a vibrating-wire piezometer for measuring pressure. In a cold environment, the steel string inside the vibrating-wire piezometer shrinks, causing distortion of the monitoring results. Summary of the invention

[0045] Embodiment 1:

[0046] A remote slope monitoring system, referring to Figure 1, including a monitor, a transmitter and a data management platform. The monitor is installed on the slope to monitor the status of the slope. The transmitter is connected to the monitor to receive the data monitored by the monitor; the data management platform is connected to the transmitter through 5G, GPRS, NB-loT, Lora or Beidou GNSS communication to receive the data received by the transmitter and perform real-time updates and statistics.

[0047] The detector includes a vibrating-wire piezometer to monitor the seepage water pressure inside the soil at the slope. Furthermore, in this embodiment, the detector also includes a displacement stack, a crack meter, and an inclinometer to further monitor the displacement, crack width, and inclination angle generated at the slope.

[0048] The detector transmits the monitored data to the transmitter, and further transmits the data to the data management platform through 5G, GPRS, NB-loT, Lora or Beidou GNSS. In this embodiment, Beidou GNSS is preferably wirelessly connected to the transmitter, and static relative positioning technology is used to locate the position of the slope.

[0049] The static relative positioning technology uses phase measurement pseudorange observations as the basic observation quantities. The receivers (GNSS base stations) set at the two end points of the baseline are fixed relative to the surrounding reference objects. Sufficient redundant observation data are obtained through continuous observation to solve the baseline vector.

[0050] The difference between two different Beidou GNSS satellites for the same station is called inter-satellite single difference, which can effectively eliminate or weaken the error related to the station. Relative positioning is the most accurate method in current satellite positioning, with an accuracy of millimeter level, which can ensure the accuracy of monitoring and the real-time nature of monitoring data.

[0051] The implementation principle of Example 1 of the present application is:

[0052] Based on 5G, GPRS, NB-loT, Lora or Beidou GNSS technology, the slope position can be located more accurately to ensure the accuracy of monitoring.

[0053] Embodiment 2:

[0054] Reference Figures 2 to 4 The difference between this embodiment and embodiment 1 is that the vibrating-wire osmometer includes a temperature regulating component, and the temperature regulating component enables the vibrating-wire osmometer to still have a high measurement accuracy in cold areas.

[0055] The vibrating-wire osmometer comprises an outer protective tube 1, a steel string 2 and a steel string fixing sleeve 8. One end of the outer protective tube 1 is sealed, and the other end of the outer protective tube 1 is connected to a flexible membrane 4. The steel string 2 and the steel string fixing sleeve 8 are coaxially arranged in the outer protective tube 1, wherein the steel wire protection sleeve is arranged on the steel string 2 to provide external protection for the steel string 2 and ensure that the steel string 2 is installed in place.

[0056] Furthermore, one end of the steel string 2 is fixed, and the other end of the steel string 2 is used to receive the pressure transmitted by the flexible membrane 4. A mounting hole 81 is provided on the protective cover of the steel string 2, and an induction coil 9 is provided in the mounting hole 81 for sensing the vibration frequency of the steel string 2, thereby measuring the pressure.

[0057] The actions for measuring pressure are as follows:

[0058] A permeable stone 5 is arranged on the side of the flexible membrane 4 facing away from the steel string 2. The permeable stone 5 is arranged at a distance from the flexible membrane 4 to form a chamber. When water enters the chamber through the permeable stone 5, it pushes the flexible membrane 4, thereby causing the flexible membrane 4 to deform, and the flexible membrane 4 further pushes the steel string 2 to move. Since one end of the steel string 2 is fixed, the steel string 2 is in a compressed state at this time, and the vibration frequency of the steel string 2 changes.

[0059] By applying external force to the steel string 2 through the induction coil 9, the resonant frequency signals corresponding to the steel string 2 when the flexible membrane 4 is not deformed and deformed are recorded as f0 and fi respectively, and then according to the formula: P = K (fi 2 -f0 2 ), the permeate water pressure is calculated, (wherein, f0 is the initial frequency value, corresponding to the state when the flexible membrane 4 is not deformed, fi is the working frequency value, corresponding to the state when the flexible membrane 4 is deformed, K is the sensitivity coefficient, and P is the pressure value).

[0060] However, in actual work, since the length of the steel string 2 is affected by temperature, that is, it will expand when heated and shrink when cooled, according to the vibration frequency formula f = 0.5L (T / ρ) 0.5 , (where L is the length of the steel string 2, T is the string tension (stress), and ρ is the string density). It can be clearly found that when the length of the steel string 2 changes, the obtained vibration frequency will deviate greatly from the actual value, especially when the piezometer is in a cold environment, the steel string 2 will shrink, resulting in the steel string 2 not being well fixed.

[0061] Therefore, in this embodiment, the above-mentioned low temperature adjustment component 3 is arranged in the outer protective tube 1 to prevent the length of the steel string 2 from changing, thereby achieving the purpose of automatically correcting the monitoring data.

[0062] Specifically, refer to Figure 2 and Figure 3The low temperature adjustment component 3 is arranged at the end of the steel string 2 away from the flexible membrane 4 to fix the steel string 2. Specifically, the low temperature adjustment component 3 includes a fixing block 31, an infrared transmitter 32, an infrared receiver 33 and a heating plate 34. The fixing block 31 is fixedly connected to the outer protective tube 1 and is provided with a fixing groove 311 coaxially arranged with the steel string 2. The end of the steel string 2 away from the flexible membrane 4 extends into the fixing groove 311 and can be against the bottom wall of the fixing groove 311.

[0063] Furthermore, the infrared transmitter 32 and the infrared receiver 33 are arranged on the peripheral side wall of the fixing groove 311, wherein the transmitting end of the infrared transmitter 32 is perpendicular to the end of the steel string 2 abutting against the fixing hole, and the infrared receiver 33 is connected to the heating plate 34 (preferably wirelessly connected);

[0064] When the steel string 2 does not shrink, the end of the steel string 2 abuts against the bottom wall of the receiving hole, the infrared transmitter 32 is blocked by the steel string 2, the light emitted by its transmitting end does not fall on the infrared receiver 33, and the heating plate 34 is turned off.

[0065] When the steel string 2 does not block the emitting end of the infrared transmitter 32 (that is, when the steel string 2 contracts), the end of the steel string 2 is matched with the bottom wall of the accommodating hole to form a gap. Correspondingly, the light emitted by the infrared transmitter 32 is no longer blocked by the steel string 2, and the light emitted by the emitting end does not fall on the infrared receiver 33. The infrared receiver 33 transmits a signal to the heating plate 34, and the heating plate 34 works.

[0066] The heating plate 34 can heat the steel string 2, so that the steel string 2 fits with the bottom wall of the fixing groove 311 again, so that the steel string 2 can be in a compressed state when receiving the pressure transmitted by the flexible membrane 4, thereby ensuring the accuracy of the monitoring data. In addition, in this embodiment, the end of the steel string fixing sleeve 8 away from the flexible membrane 4 is provided with a mounting groove 82, and the low temperature adjustment component 3 is arranged in the mounting groove 82. By setting the mounting groove 82, the low temperature adjustment component 3 is fixed, and at the same time, it can also ensure that when the temperature adjustment component is installed, the fixing groove 311 is coaxially arranged with the steel string 2 to ensure that it is installed in place.

[0067] Monitoring data further refers to Figure 2 and Figure 4 A pressure-bearing membrane 6 is arranged on the side of the flexible membrane 4 facing away from the permeable stone 5, and one end of the steel string 2 close to the flexible membrane 4 is fixed on the pressure-bearing membrane 6, and the pressure-bearing membrane 6 is slidably connected in the outer protective tube 1 and is spaced apart from the flexible membrane 4. A receiving cavity 10 is formed between the pressure-bearing membrane 6 and the flexible membrane 4, and the receiving cavity 10 is filled with a pressure-transmitting liquid 20, and the freezing point of the pressure-transmitting liquid 20 is lower than the freezing point of water (oil substances, such as thermal conductive silicone oil, or alcohol substances, such as ethanol, can be used).

[0068] When water penetrates the permeable stone 5 and causes the flexible membrane 4 to deform, the flexible membrane 4 will further squeeze the pressure-transmitting liquid 20 in the accommodating chamber 10, causing the pressure-bearing membrane 6 to slide, thereby driving the steel string 2 to move. While transmitting pressure, the steel string 2 and the flexible membrane 4 are separated by the pressure-transmitting liquid 20, preventing water from directly contacting the pressure-bearing membrane 6 and the steel string 2, causing ice to condense on the pressure-bearing membrane 6 or the steel string 2, resulting in frost heave. While ensuring measurement accuracy, the steel string 2 and the pressure-bearing membrane 6 are protected.

[0069] It should be noted that, in practice, the movement of the pressure-bearing membrane 6 is microscopic and difficult to observe with the naked eye. The movement of the pressure-bearing membrane 6 is only to better drive the steel string 2 so that the steel string 2 presses the hole wall of the fixing groove 311 and is in a compressed state.

[0070] Further, refer to Figure 2 Sealing rings 30 are attached to both sides of the pressure-bearing membrane 6. The sealing rings 30 are made of elastic material (preferably silicone material) so that they fit tightly with the inner wall of the outer protective tube 1. The outer ring of the sealing ring 30 is sealed and slidably connected to the inner wall of the outer protective tube 1 to prevent the pressure-transmitting liquid 20 from passing through the pressure-bearing membrane 6 and infiltrating into the space between the low-temperature adjustment component 3 and the pressure-bearing membrane 6, resulting in a deviation between the transmitted pressure and the actual pressure.

[0071] In addition, refer to Figure 2 and Figure 4 A through hole 61 is opened in the center of the pressure-bearing membrane 6, and the end of the steel string 2 facing away from the low-temperature adjustment component 3 passes through the through hole 61 and is fixed to the pressure-bearing membrane 6. The steel string 2 partially extends into the accommodating cavity 10 to transfer heat to the pressure-transmitting liquid 20.

[0072] When in a low temperature state, the heating plate 34 not only prevents the steel string 2 from shrinking, but also generates heat which can be transferred to the pressure-transmitting liquid 20 through the steel string 2 to prevent the pressure-transmitting liquid 20 from freezing due to its excessively low temperature. The pressure-transmitting liquid 20 can also further transfer heat to the flexible membrane 4 and the permeable stone 5, thereby protecting the flexible membrane 4 and reducing the possibility of water freezing and failing to pass through the permeable stone 5 smoothly.

[0073] Furthermore, a fixing part 7 is provided in the accommodating cavity 10 for fixing the steel string 2 on the pressure-bearing membrane 6, and the fixing part 7 includes a capillary 71 and a filler 72, wherein the capillary 71 is sleeved on the steel string 2 and connected to the pressure-bearing membrane 6 (preferably by welding, and in other embodiments, the capillary 71 and the pressure-bearing membrane 6 can also be integrally formed through a mold or a machine tool), and the filler 72 fills the gap between the steel string 2 and the capillary 71.

[0074] When the steel string 2 is fixed to the pressure-bearing membrane 6 , the capillary tube 71 is punched so that the capillary tube 71 , the filler 72 and the steel string 2 are relatively fixed, thereby achieving a permanent connection between the steel string 2 and the pressure-bearing membrane 6 .

[0075] Compared with detachable connection forms such as bolts and screws, it can prevent the connection between the steel string 2 and the pressure-bearing membrane 6 from loosening or creeping, thereby preventing the steel string 2 from "drifting"; at the same time, while fixing the steel string 2 to the pressure-bearing membrane 6, it can prevent the pressure-transmitting liquid 20 from passing through the pressure-bearing membrane 6 from the through hole 61 and penetrating into the space between the low-temperature adjustment assembly 3 and the pressure-bearing membrane 6.

[0076] The implementation principle of Example 2 of the present application is:

[0077] By providing the low temperature adjustment component 3, when the steel string 2 is affected by the low temperature and shrinks, the heating sheet 34 can heat the steel string 2, so that the steel string 2 fits with the bottom wall of the fixing groove 311 again, so that the steel string 2 can be in a compressed state when receiving the pressure transmitted by the flexible membrane 4;

[0078] At the same time, the flexible membrane 4 can separate the pressure-bearing membrane 6 and the permeable stone 5. When transmitting pressure, the steel string 2 and the flexible membrane 4 are separated by the pressure-transmitting liquid 20, which can prevent water from directly contacting the pressure-bearing membrane 6 and the steel string 2, so that ice condenses on the pressure-bearing membrane 6 or the steel string 2, causing frost heave.

[0079] Correspondingly, the steel string 2 extends into the accommodating cavity 10. When the steel string 2 shrinks due to the low temperature and the heating plate 34 heats the steel string 2, the heat can also be conducted to the pressure-transmitting liquid 20, and further heat the flexible membrane 4 and the permeable stone 5, thereby protecting the steel string 2 and the pressure-bearing membrane 6 while ensuring the measurement accuracy.

[0080] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
