Description

Technical Field

[0001] This utility model relates to a monitoring device, specifically an automated monitoring device for tunnel deformation control, belonging to the field of tunnel technology. Background Technology

[0002] Tunnels are engineering structures buried underground, representing a form of human utilization of underground space. Tunnels can be categorized into traffic tunnels, hydraulic tunnels, municipal tunnels, and mining tunnels.

[0003] A search revealed a remote automated monitoring and early warning system for the deformation of the secondary lining of an operational tunnel, disclosed in Chinese Patent Publication No. CN210719053U. This system includes a deformation acquisition terminal, a data transmission system, and a monitoring and early warning platform. The deformation acquisition terminal comprises arch crown measuring devices, arch waist measuring devices, and sidewall measuring devices, each consisting of a transmitter and receiver symmetrically arranged. This system, through continuous real-time automated monitoring of the secondary lining of an operational tunnel, can obtain the deformation cross-sectional contour of the tunnel lining structure and the deformation evolution law of the tunnel lining structure over time. This improves the economic efficiency of monitoring, ensures the safety of tunnel operation, and can be widely applied to automated monitoring of municipal, highway, railway, subway, tunnel, and culvert projects.

[0004] While the above solutions can improve the economic efficiency of monitoring and ensure the safety of tunnel operation, the patents mentioned above are difficult to provide guidance for on-site staff. Due to the excessive length of some tunnels, when local deformation occurs, staff need to check each section one by one to find the main deformation location. They cannot set up barriers and repair the deformation location in time to evacuate people and vehicles, which poses a great safety hazard. Therefore, we provide an automated monitoring device for tunnel deformation control to solve the above problems. Utility Model Content

[0021] This invention provides an automated monitoring device for tunnel deformation control.

[0022] Please see Figure 1 The device includes a main shell 1, and an anchor 16 is fixedly connected to the bottom of the main shell 1. The anchor 16 has bolt holes. The purpose of setting the anchor 16 is to fix the monitoring device of this application to the surface of the tunnel lining structure, which is conducive to the subsequent real-time acquisition of strain, displacement and temperature data.

[0023] Please see Figure 1 The top of the main body shell 1 is fixedly connected to a strain sensor 13, a displacement sensor 14 and a temperature compensation sensor 15. On the surface of the tunnel lining structure, a sensor array is arranged every 5-10 meters along the axial direction. The sensor array includes a strain sensor 13, a displacement sensor 14 and a temperature compensation sensor 15. The strain sensor 13 uses a Bragg grating structure.

[0024] Please see Figure 1 An edge computing module 12 is fixedly connected to the other side of the main shell 1. The edge computing module 12 integrates signal demodulation and AI algorithms to realize data preprocessing and deformation trend prediction. The edge computing module 12 consists of an integrated fiber optic demodulator, a microprocessor and a storage unit. The demodulator uses wavelength scanning to convert optical signals into electrical signals and perform analog-to-digital conversion. The microprocessor calls the machine learning algorithm module, inputs historical monitoring data, geological parameters and environmental data, and outputs the deformation prediction value for the next 72 hours.

[0025] Please see Figure 1A wireless communication unit 11 is fixedly connected to one side of the main shell 1. The wireless communication unit 11 includes an encrypted transmission module and an antenna. The wireless communication unit 11 transmits data to a cloud management platform using the LoRaWAN protocol. The platform visualizes the tunnel's health status through a BIM model and triggers a multi-level early warning mechanism based on thresholds. After receiving the data, the cloud management platform updates the deformation parameters of the BIM model and generates a three-dimensional visualized cloud map. The finite element analysis module recalculates the structural stress distribution based on real-time data, providing a basis for maintenance decisions.

[0026] Please see Figure 2 A copper sheet 9 is fixedly connected to the inner wall of the main body shell 1. The main body shell 1 has a sound amplification groove 10. The purpose of setting the copper sheet 9 is that when the copper sheet 9 is hit, it will emit a loud sound, thereby alerting the personnel on site.

[0027] Please see Figure 2 The inner wall of the main body shell 1 is fixedly connected to the mounting base 2, and the inner wall of the mounting base 2 is fixedly connected to the DC motor 3. The output shaft of the DC motor 3 is fixedly connected to the force-applying plate 4. The purpose of setting the DC motor 3 is to effectively provide sufficient power support for the rotation of the force-applying plate 4. The DC motor 3 is existing publicly available technology, and this application will not elaborate further on the DC motor 3.

[0028] Please see Figure 2 and Figure 3 A control ring 5 is rotatably connected to one side of the force-applying plate 4. The force-applying plate 4 can apply a control effect to the control ring 5, thereby ensuring the stability of the control ring 5. A guide rod 6 is slidably connected to the inner wall of the control ring 5. The cooperation between the control ring 5 and the guide rod 6 allows the movement of the control ring 5 to drive the guide rod 6 to swing when the guide rod 6 is restricted.

[0029] Please see Figure 2 and Figure 4 One end of the guide rod 6 is fixedly connected to an impact rod 7. The guide rod 6 and the impact rod 7 are directly connected and maintain a linkage effect. The purpose of setting the impact rod 7 is to strike the two copper pieces 9 by swinging, thereby producing a rapid sound. The other end of the guide rod 6 is fixedly connected to a positioning and steering component 8. The positioning and steering component 8 is rotatably connected to one side of the mounting base 2. The mounting base 2 can apply a positioning control effect to the positioning and steering component 8 to ensure that the positioning and steering component 8 can rotate at a fixed point.

[0030] Please see Figure 1 and Figure 2In this application, the edge computing module 12 is electrically connected to the strain sensor 13, the displacement sensor 14, the temperature compensation sensor 15 and the DC motor 3, respectively. The wireless communication unit 11 is communicatively connected to the edge computing module 12, and the cloud management platform interacts remotely with the wireless communication unit 11. Some of these interactions are not described, but are all basic common knowledge for those skilled in the art.

[0031] Working principle: During use, strain sensor 13, displacement sensor 14, and temperature compensation sensor 15 are fixed to the surface of the tunnel lining structure through anchors 16 to collect strain, displacement, and temperature data in real time. Edge computing module 12 integrates signal demodulation and AI algorithms to realize data preprocessing and deformation trend prediction. Wireless communication unit 11 uses LoRaWAN protocol to transmit data to cloud management platform. The platform visualizes the tunnel health status through BIM model and triggers a multi-level early warning mechanism based on threshold, realizing full-time automated monitoring of tunnel deformation. When edge computing module 12 controls DC motor 3 to start, it will drive control collar 5 to move through force plate 4. At this time, because the positioning steering component 8 combined with guide rod 6 is restricted by the mounting base 2, control collar 5 can drive impact rod 7 to swing through guide rod 6, so that impact rod 7 strikes copper plate 9 and emits a rapid sound to remind on-site personnel, so that on-site personnel can find the position more quickly and avoid aggravating tunnel deformation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
