A recorder 103 is mounted on the mounting shaft. A camera unit 102 is located in front of the recorder 103, and an alarm 105 is located on its left or right side. A support rod 110 is fixedly connected to the lower side of the support box 104, and a base 109 is fixedly connected to the lower side of the support rod 110. A data processing unit 107 is connected to the left or right side of the base 109. The base 109 has a built-in first battery. The data processing unit 107 is electrically connected to the antenna 101, camera unit 102, recorder 103, alarm 105, and laser light 106. The first battery is also electrically connected to these components. The tunnel entrance signal transmitter 2 is wirelessly connected to the laser device 1.

[0034] Laser device 1 emits laser light and collects the reflected laser light. At the same time, camera unit 102 takes pictures. By comparing video recordings or photos of the same location at different times, the changes in the soil are analyzed and sorted out. When an alarm is needed, the tunnel entrance signal transmitter 2 sends out an alarm signal.

[0035] like Figure 1 As shown, the laser device 1 also includes a solar panel 111 and a rotating tension rod 112. The solar panel 111 is connected to the left or right side of the base 109 via the rotating tension rod 112. The solar panel 111 is connected to the first battery.

[0036] The alarm 105 is connected to the carrier box 104 via a flexible tube.

[0037] For example, laser lights 106 are arranged in a 3x3 matrix.

[0038] Optionally, the base 109 is connected to the data processing unit 107 via a folding extension rod 108.

[0039] For example, the folding extension rod 108 is a three-section folding rod.

[0040] like Figure 2As shown, the tunnel entrance signal transmitting device 2 includes a laser lens 1061, a laser lamp housing 1062, a first drive rod 1063, a second drive rod 1064, and a fixing platform 1065. The fixing platform 1065 includes a mounting base and a mounting column disposed in the middle of the mounting base. The second drive rod 1064 is fixedly connected to the fixing platform 1065. The first drive rod 1063 is disposed on the upper side of the second drive rod 1064. The laser lamp housing 1062 is fixedly connected to the upper side of the first drive rod 1063. The laser lamp housing 1062 has a built-in laser emitting component and a laser lens 1061 disposed at its front end.

[0041] For ease of installation, the mounting base 1065 is provided with multiple nut holes 1066, which are used to fix it to other devices.

[0042] like Figure 3 As shown, the signal transmitting device 2 includes a signal transmitting device box 201, a support rod 202, a second battery 203, and a signal plate 204. The lower end of the signal transmitting device box 201 is provided with an extension section, which is rotatably connected to the support rod 202 via a rotating shaft. The cross-sectional area of ​​the support rod 202 gradually decreases from top to bottom. The second battery 203 and the signal plate 204 are provided inside the signal transmitting device box 201, and the second battery 203 and the signal plate 204 are electrically connected.

[0043] For example, the signal transmitting device box 201 is made of corrosion-resistant alloy material and has an external arc-shaped design.

[0044] For example, there are 3 signal transmitting devices 2, which are respectively set on the left and right sides and the top side of the tunnel entrance.

[0045] In the above embodiments, antenna 101 serves to receive signals from the tunnel entrance signal transmission system, quickly feed back the received signals to laser device 1 for analysis, and also alert relevant personnel to carry out emergency repairs via signals emitted by antenna 101, prompting alarm 105 to sound an alarm quickly. When the threshold is exceeded, a special signal source is emitted, and upon receiving the signal, alarm 105 is immediately activated, and relevant personnel are notified through the system. When the threshold is not exceeded, a normal signal is emitted, and antenna 101 does not activate alarm 105, but instead allows the recorder to record and analyze the captured photos.

[0046] Camera unit 102: Monitors the soil in real time through video recording and photography. Based on received instructions, it magnifies and examines specific soil sections to observe subtle changes in the soil, recording these changes via video and photographs. It can also be remotely controlled to observe localized areas of the soil; when the slippage increases, it captures changes in the entire mountainside, which are then analyzed and processed by the recorder. For example, camera unit 102 can be a video camera, camera, etc.

[0047] Recorder 103: Records video and photographs taken by the camera, analyzes and organizes these videos and photographs to identify changes in the soil throughout the entire process. The recorder then sends the organized photographs to the data processing unit 107, which analyzes the photographs to derive patterns.

[0048] Carrying box 104: It supports other equipment, mainly laser lights, and the recorder 103 can be stored in the carrying box 104 for easy retrieval.

[0049] Alarm 105: Receives signals via antenna 101. If the landslide is significant, alarm 105 will promptly sound an alarm, notifying passing vehicles and relevant personnel to conduct emergency repairs, ensuring public safety. For example, the alarm could be a buzzer or a warning light, etc.

[0050] Laser Lamp 106: Laser Lamp 106 adopts a grid laser lamp, which better scatters the grid onto the mountain and better monitors the landslide of the mountain. The laser lamp 106 illuminates the soil in a grid pattern, which can better analyze the relative landslide of the soil within the grid and better analyze the landslide of each grid. By summarizing the whole, the variation law of landslide of the soil around the tunnel entrance can be obtained.

[0051] Data processing unit 107: The function of data processing unit 107 is to receive photos sent by recorder. Recorder 103 organizes the photos and sends them to data processing unit 107 for analysis and plotting. Data processing unit 107 analyzes the photos, organizes the slip patterns on the photos onto the plot, marks the size, and draws relevant analysis plots. Then, it performs further manual analysis based on the plots to obtain the variation pattern of soil slip at the tunnel entrance. It can also analyze the slip amount caused by vibration loss from different vehicles, and more effectively analyze the impact of different vibrations on the tunnel entrance.

[0052] Folding tension rod 108: Its function is to connect the data processing unit 107 and the support rod 110, which facilitates manual data collection. It can also be disassembled and folded, and can better protect the data processing unit 107 during the summarization process.

[0053] Base 109: A device that supports all equipment. It can be used to install equipment on the ground to fix it in place, or the entire set of equipment can be installed on another device at the tunnel entrance. The base 109 contains a battery that is connected to each device to provide power to each device and to collect the energy stored in the solar panels so that the entire device can always be in normal working condition.

[0054] Support rod 110: Connects to other equipment. The interior of support rod 110 is hollow, containing the power cables connecting the battery to various devices, and also protecting the cables from damage. It also supports the connection of equipment above.

[0055] Solar Panel 111: The solar panel is a standard component of this device, storing energy for the batteries inside the base. On sunny days, the energy stored in the solar panel powers the entire device and also stores energy for the batteries inside the base. On cloudy or rainy days, the power output of the solar panel decreases, at which point the batteries inside the base must provide energy. This cycle continues, ensuring the device does not malfunction due to insufficient power, allowing it to operate more efficiently.

[0056] Rotary tension rod 112: By using rotation, the solar panel 111 can better absorb sunlight and store more energy.

[0057] The working principle of the phased array tunnel entrance deformation monitoring system provided by this utility model is as follows: The operating equipment, including the camera unit 102, recorder 103, and data processing unit 107, is powered on simultaneously. All equipment is in normal working condition. The laser lamp 106 emits a red laser grid. The use of a grid laser lamp facilitates the formation of the laser grid. Because the laser lamp 106 is rotatable, the laser grid can be distributed across various parts of the mountain. The laser grid is fixed in a specific area of ​​the mountain being monitored for a relatively long period, allowing the camera unit 102 to capture photos. The recorder 103 records the captured videos and photos. The entire crack formation process is then analyzed and compiled. These videos and photos can be stored for easy copying by staff for further analysis and record storage. The recorder 103 sends the compiled photos to the data processing unit 107. The data processing unit 107 analyzes these photos and draws a schematic diagram of the crack, including dimensions and other relevant data. The compiled data can be remotely transmitted to the operating terminal via a communication network for final data collection and processing.

[0058] When a landslide occurs, signal transmitters 2 installed around the tunnel send signals to laser device 1. The signal source emitted by transmitters 2 varies depending on the degree of landslide, allowing laser device 1 to determine the magnitude of the landslide. A specific value is set, and when the landslide reaches that value, alarm 105 is activated; otherwise, a normal signal is emitted for pattern analysis. The three signal transmitters 2 installed around the tunnel correspond precisely to the three directions of pressure exerted by the mountain on the tunnel, providing comprehensive coverage of the entire tunnel entrance.

[0059] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0060] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0061] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
