Description

Technical Field

[0001] The present invention relates to the technical field of deformation monitoring, and in particular to an aqueduct deformation monitoring device based on Beidou high-precision positioning and measurement technology. Background Art

[0002] Aqueducts are overhead water channels that carry water across rivers, valleys, depressions and roads. They are commonly used for irrigation and water delivery, as well as flood and sand drainage. Large aqueducts can also be navigable. When the span of an aqueduct is large, the reinforced concrete structure is difficult to meet the crack control requirements and is prone to deformation. Therefore, real-time monitoring of the deformation of the aqueduct bridge is required.

[0003] The deformation monitoring equipment for aqueduct bridges is mainly composed of sensor systems, signal acquisition and processing systems, communication systems and monitoring centers. The Beidou satellite navigation system is widely used in the health monitoring of aqueduct bridges due to its many advantages such as all-weather, high precision, high frequency and real-time performance.

[0004] Among them, the Beidou satellite navigation system consists of three parts: the space end, the ground end and the user end. It can provide high-precision, high-reliability positioning, navigation and timing services to all types of users around the world all day and all day, and has short message communication capabilities. It has initially acquired regional navigation, positioning and timing capabilities, with positioning accuracy at the decimeter and centimeter level, speed measurement accuracy of 0.2 meters per second, and timing accuracy of 10 nanoseconds.

[0005] In existing deformation monitoring, data transmission generally uses 4G network technology to transmit the original monitoring data in real time to the background server data center for centralized data processing. However, signal transmission is limited in mountainous areas with poor network. In addition, due to the poor accuracy and stability of GPS monitoring, it takes a long time from sending data to the server, to the server solving high-precision post-event results, and then to manually sending early warning notifications, which is not conducive to real-time monitoring of aqueduct deformation.

[0006] The monitoring device is generally installed at the monitoring point through a metal fastening mechanism. During the long-term fastening process, the fastening mechanism of the metal material will produce plastic deformation due to the long-term fastening. No matter how the strength of the metal fastening mechanism or the number of fastening bolts is increased, it is impossible to avoid the loosening of the fastening mechanism due to the long-term force, causing the monitoring device to shake, resulting in deviations in the monitoring data. In traditional monitoring systems, due to the influence of signal noise and algorithm model errors, there is usually an error of 5mm-10mm. Therefore, it is difficult to determine whether the fluctuations in the results are due to the actual deformation of the aqueduct or the influence of the monitoring device itself. The long-term deformation trend of the monitored object can only be seen based on the long-term monitoring result time series, which is not conducive to real-time monitoring of the aqueduct deformation. Summary of the invention

[0007] In order to overcome the defects of the prior art, the purpose of the present invention is to provide an aqueduct deformation monitoring device based on Beidou high-precision positioning and measurement technology, so as to realize real-time monitoring and timely warning, and improve the accuracy of monitoring data.

The top end of the adjustable clamping plate is rotatably connected to one end of the T-shaped base so that the installation space is consistent with the shape of the aqueduct side railing.

[0010] Furthermore, the T-shaped base includes a support base, a fixed vertical plate and a first fixing bolt installed on the fixed vertical plate. The Beidou receiver and the power module are installed at one end of the support base, and a second fixing bolt is installed on the adjustable clamping plate.

[0011] Furthermore, the adjustable splint includes two vertical rods and a reinforcing horizontal plate, the other end of the support seat extends outward on both sides to form connecting ears, the top of the vertical rod is rotatably connected to the end of the connecting ear through a fixing pin, and the second fixing bolt is installed on the reinforcing horizontal plate.

[0012] Furthermore, a tightening spring is sleeved on the second fixing bolt, and the tightening spring is arranged between the inner surface of the adjustable clamping plate and the outer wall of the aqueduct.

[0013] Furthermore, the top end of the vertical rod and the end of the connecting ear are respectively provided with slots, and the fixing pin is arranged through the slots.

[0014] Furthermore, the power module includes a battery and a solar panel, the battery is installed on the support seat, and the solar panel is tiltedly installed on the casing of the Beidou receiver through a connecting rod.

[0015] Furthermore, a mounting base is provided at the bottom end of the Beidou receiver, and the mounting base is fixed to the supporting base by bolt connection.

[0017] 1) The present invention combines Beidou positioning technology with 5G communication technology, uses high-precision Beidou technology to monitor the deformation of the aqueduct, and wirelessly transmits the monitoring data through 5G technology, thereby solving the problems of poor accuracy and stability of GPS monitoring and long data transmission time in the prior art, and realizing real-time monitoring of the aqueduct deformation.

[0018] 2) The monitoring device in the present invention is installed on the monitoring point of the aqueduct bridge through a fixing mechanism.
