Description

Technical Field

[0001] The present invention belongs to the technical field of tunnel deformation monitoring, and in particular relates to a method, device, system and medium for monitoring an asymmetric deformation tunnel. Background Art

[0002] With the rapid development of transportation infrastructure, tunnels are widely used as key engineering structures that connect geographical space and improve transportation efficiency. However, the complexity and diversity of tunnel structures make tunnels vulnerable to various diseases during use, such as deformation, cracks, leakage, erosion, etc. These diseases not only affect the normal use and safety of tunnels, but may also cause serious economic losses and social harm.

[0003] In order to improve traffic safety, the existing tunnel deformation monitoring uses radar systems to achieve tunnel deformation monitoring. For example, the "A Tunnel Deformation Monitoring and Early Warning Radar System" with application number 202010786387.3, which is equipped with at least 4 deformation monitoring radar modules, which are distributed in a triangular cone and are used to detect the target to be measured. Three of them are distributed in the same section of the tunnel, located at the top of the tunnel and on both sides of the tunnel, and the remaining one is located on any side a few meters away from the previous section, which is used to detect the distance of the target in the direction of the radar line of sight. The first installation requires a total station to measure the three-dimensional coordinates of each radar module relative to the geodetic coordinate system; the router connects the cloud platform and establishes a local area network for radar system information transmission, and the communication module of the deformation monitoring radar module transmits signals to the central processor through a wireless WiFi local area network link; the central processor receives at least four data channels, respectively solves the distance information between the radar and the target, and uses the positioning algorithm to obtain the three-dimensional coordinates of the target according to the three-dimensional coordinates of the measured radar and the corresponding distance information, so as to realize deformation monitoring.

[0004] However, the existing technology has the following problems:

[0005] 1. Using the above technology, the number of deformation monitoring radar modules must be at least 4 to spatially locate the target angle. The number of deformation monitoring radar modules is large, and the monitoring cost is high.

[0006] 2. Complex installation. During the installation process, it is necessary to use a total station to set control points inside the tunnel to accurately determine the spatial coordinates of the radar and the angle reflector inside the tunnel and install them. This method will greatly increase the difficulty of on-site construction.

[0007] 3. Based on the ranging results of multiple radars, the spatial coordinate system of the target angle is inverted using the principle of spherical intersection. Therefore, the errors of installation and measurement will accumulate with each other, and the accuracy of deformation monitoring is low.

[0008] 4. The coordinate system used for inversion is based on the measurement data of a fixed measurement reference point, and the radar deployed in the tunnel is also in the same tunnel deformation interval. Its coordinates may also change with the deformation of the surrounding rock, that is, the spatial coordinates of the radar measured by the total station at the second point will change, resulting in the inversion result not being the actual deformation result of the tunnel. For example, if the tunnel area where the radar is installed is deformed, but the tunnel in the angle reflection area is not deformed, but according to the inversion result, it is believed that the tunnel in the area monitored by the angle reflection is deformed; for example, if the location of a certain radar is deformed, then all the monitoring data results participating in the inversion will have a large error. Summary of the invention

[0009] In order to solve the problems of large number of equipment, high monitoring cost and low accuracy in existing methods, the present invention provides an asymmetric deformation tunnel monitoring method, device, system and medium, which reduces the number of equipment and monitoring cost, is simple to install, and improves the monitoring accuracy of asymmetric deformation.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The present invention discloses a method, a device, a system and a medium for monitoring an asymmetric deformation tunnel, wherein the device realizes asymmetric deformation detection based on the method and the device is a part of the system.

[0035] Specifically, the system includes an angle reflector, a radar, an asymmetric deformation tunnel deformation monitoring device, and a communication unit. The communication unit is used to realize data transmission between the radar and the asymmetric deformation tunnel monitoring device. The angle reflector and the radar are used in combination to realize the measurement of distance and angle.

[0036] Among them, Figure 1 As shown, the angle counter includes a first angle counter 21, a second angle counter 22 and a third angle counter 23 which are installed on the same section of the tunnel to be monitored during real-time monitoring, and the second angle counter 22 is installed in the middle of the arch of the tunnel, and the first angle counter and the third angle counter are symmetrically arranged on the side walls on both sides with the central axis of the tunnel as the symmetry axis.

[0037] The radar includes a first radar 11 and a second radar 12, which are placed on the same tunnel cross section as the angle reflector. The first radar and the second radar are used to be arranged 0.5 meters to 1.5 meters below the first angle reflector and symmetrically arranged on the side walls on both sides with the central axis of the tunnel as the symmetry axis. The radar can be any one of centimeter-wave radars, microwave radars, photoelectric radars or millimeter-wave radars that can measure both distance and angle. In order to improve the accuracy of asymmetric deformation judgment and deformation calculation, the radar preferably uses high-precision radars, such as microwave radars and millimeter-wave radars. In this solution, in order to improve the monitoring accuracy, the installation position of the radar cannot be too far away from the angle reflector in the vertical direction, so that the angle change between the first angle reflector, the first radar and the second radar can be ignored in real-time monitoring. , the angle change between the third angle reflector, the second radar, and the first radar The impact on deformation monitoring; at the same time, the installation position of the radar cannot be too close to the angle reflection to avoid the angle reflection interfering with the radar's tracking and identification accuracy of the target.

[0038] Before real-time monitoring, the first radar needs to collect the angle between the first angle reflector and the second radar. The second radar also needs to collect the angle between the third angle reflection and the first radar At this time, the first angle reflector 21 and the third angle reflector 23 can be used as temporary angle reflectors. The first radar collects the angle between the first angle reflector and the second radar. When the third angle inversion is used as a temporary angle inversion, it is installed at the position of the second radar with the help of auxiliary equipment such as a level or a total station, and cooperates with the first angle inversion to realize the data collection of the first radar. Similarly, the angle between the second radar collection and the third angle inversion and the second radar When the first angle inversion is used as a temporary angle inversion, it is installed at the position of the first radar with the help of auxiliary equipment such as a level or a total station, and cooperates with the third angle inversion to realize the data collection of the second radar.

[0039] The communication unit is used to realize data transmission between the radar and the asymmetric deformation tunnel monitoring device. The communication unit has multiple options according to the distance between the radar and the symmetric deformation tunnel monitoring device. If the distance between the two is close, it can be a data transmission line; if the distance between the two is far, it can be a remote communication unit.

[0040] After obtaining the above angle data with the assistance of temporary angle reflection or total station, Figure 1 The structure shown in the figure is equipped with radar and angle reflector. At this time, the radar detects the remaining initial monitoring data, including the distance d between the first radar and the first angle reflector. 11 , the distance d between the first radar and the second radar 21 , the distance between the second radar and the second angle , the distance d between the second radar and the third angle31 , the angle θ between the first radar and the first angle anti-, the second angle anti- 11 , the angle θ between the second radar and the third angle anti-, the second angle anti- 21 The angle between the first radar and the first angle reflector and the second radar , the angle between the second radar and the third angle, and the angle between the first radar , the distance d between the first radar and the first angle reflection 11 , the distance d between the first radar and the second radar 21 , the distance between the second radar and the second angle , the distance d between the second radar and the third angle 31 , the angle θ between the first radar and the first angle anti-, the second angle anti- 11 , the angle θ between the second radar and the third angle anti-, the second angle anti- 21 The initial monitoring data are stored together in the local asymmetric deformation tunnel monitoring device so as to be directly called when calculating the asymmetric deformation during the real-time monitoring process.

[0041] After the angle reflector and radar are deployed, they are in a state of continuous real-time data collection. At this time, the first radar needs to collect the distance d between the first radar and the first angle reflector. 12 , the distance d between the first radar and the second radar 22 , the angle θ between the first radar and the first angle anti-, the second angle anti- 12 ; The second radar needs to collect the distance d between the second radar and the third angle 32 , the distance between the second radar and the second angle reflector , the angle θ between the second radar and the second and third angles 22 .

[0042] It should be noted that Figure 1 Where n is 1 or 2. If n is 1, it indicates initial monitoring data. If n is 2, it indicates real-time monitoring data.

[0043] This solution optimizes the number and specific layout of diagonal reflections and radars, thereby further improving the monitoring accuracy of asymmetric tunnel monitoring while reducing the number of equipment.

[0044] The asymmetric deformation tunnel deformation monitoring device realizes the calculation of asymmetric deformation according to the above-mentioned real-time monitoring data and initial monitoring data, wherein the asymmetric deformation tunnel deformation monitoring device can be a smart mobile terminal, a tablet, a computer, a cloud and other smart devices. Specifically, the asymmetric deformation tunnel deformation monitoring device includes a memory and a controller that are sequentially connected in communication, and a computer program is stored on the memory, and the controller is used to read the computer program and execute an asymmetric deformation tunnel monitoring method. For example, the memory may include but is not limited to random access memory (Random-Access Memory, RAM), read-only memory (Read-Only Memory, ROM), flash memory (FlashMemory), first-in-first-out memory (First Input First Output, FIFO) and or first-in-last-out memory (First Input Last Output, FILO), etc.; the controller may not be limited to a microcontroller of the STM32F105 series. In addition, the computer device may also include but is not limited to a power supply unit, a display screen and other necessary components.

[0045] The asymmetric deformation tunnel monitoring method includes steps S01 and S02.

[0046] Step S01, in response to receiving a test instruction, receiving radar monitoring data and obtaining initial monitoring data and real-time monitoring data, the radar comprising a first radar and a second radar, the initial monitoring data comprising an angle between the first radar and the first angle reflector and the second radar in an initial state , the angle between the second radar and the third angle, and the angle between the first radar , the distance d between the first radar and the first angle reflection 11 , the distance d between the first radar and the second radar 21 , the distance between the second radar and the second angle , the distance d between the second radar and the third angle 31 , the angle θ between the first radar and the first angle anti-, the second angle anti- 11 , the angle θ between the second radar and the third angle anti-, the second angle anti- 21 The real-time monitoring data includes the distance d between the first radar and the first angle collected in real time 12 , the distance d between the first radar and the second radar 22 , the angle θ between the first radar and the first angle anti-, the second angle anti- 12 , the distance d between the second radar and the third angle 32 , the distance between the second radar and the second angle reflector , the angle θ between the second radar and the second and third angles 22; Among them, when the first radar and the second radar are collecting data, the first angle reflector, the second angle reflector, the third angle reflector, the first radar and the second radar are arranged on the same tunnel section of the tunnel, the second angle reflector is arranged in the middle of the tunnel vault, and the first angle reflector and the third angle reflector are arranged on the side walls on both sides with the tunnel central axis as the symmetry axis; the first radar and the second radar are respectively arranged 0.5 meters to 1.5 meters below the third angle reflector and the first angle reflector and are symmetrically arranged on the side walls on both sides with the tunnel central axis as the symmetry axis.

[0047] Angle reflection and radar continuously collect data. Since the environment in the tunnel is relatively complex and vehicles often pass by, and the radar measurement accuracy is relatively high, slight changes in the surrounding environment may affect the measurement results. When a car passes by, false alarms may be generated based on the real-time monitoring data collected by the radar. In this regard, in order to further improve the accuracy of monitoring, it is also possible to determine whether a car passes by at the time of real-time monitoring data collection based on the dynamic threshold set by the constant false alarm rate algorithm; when a car passes by at the time of real-time monitoring data collection, the real-time monitoring data is deleted and does not need to be used as a data source for deformation monitoring.

[0048] Step S02: Calculate the asymmetric deformation amount according to the real-time monitoring data and the initial monitoring data.

[0049] According to the requirements of deformation monitoring of construction tunnels and operating tunnels, the monitoring contents of tunnel deformation mainly include vault settlement and horizontal convergence monitoring.

[0050] To this end, in this step, the amount of vault subsidence and horizontal convergence can be calculated based on the radar monitoring data.

[0051] Specifically, for the horizontal convergence, that is, the displacement around the tunnel ,

[0052] ,

[0053] in, ,

[0054] ,

[0055] is the change in the angle between the first radar and the second radar,

[0056] is the change in the angle between the third angle reflector, the second radar and the first radar.

[0057] However, since the radar is placed 0.5 to 1.5 meters below the first corner, for tunnels with common hole diameters such as highways and railways, can be ignored, so the displacement around the tunnel is for:

[0058] .

[0059] In order to further increase the displacement around the tunnel Monitoring accuracy: When deploying the angle reflectors and radars, the first radar and the second radar are preferably deployed 0.8m to 1.2m below the third angle reflector and the first angle reflector, respectively. Specifically, they can be set at 0.9m, 1m, and 1.1m below.
