Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] Please see Figure 1-5 This utility model provides a mine displacement monitoring system, including a monitor 5 and a protective housing 1. The lower end of the protective housing 1 is provided with a base plate 2, which is installed in the area to be monitored by anchor bolts. The upper end of the protective housing 1 is open and has a receiving cavity 12. A lifting mechanism is provided in the receiving cavity 12. A support plate 3 is provided on the upper end of the lifting mechanism. The monitor 5 is installed on the upper end of the support plate 3. A rectangular positioning frame 4 is provided on the outer side of the support plate 3. Multiple connecting rods 6 are provided on the upper end of the rectangular positioning frame 4. The multiple connecting rods 6 are arranged in a rectangular shape. A first protective plate 7 is provided on the upper end of the connecting rod 6. A second protective plate 8 in an inverted V shape is provided on the upper end of the first protective plate 7. The lifting mechanism is used to drive the support plate 3 to move up and down. A moving shaft 71 is provided on the lower end of the first protective plate 7 relative to the connecting rod 6. A countersunk hole is provided on the connecting rod 6 to slide with the moving shaft 71. A first spring 72 is provided between the bottom of the countersunk hole and the bottom of the moving shaft 71.

[0023] The lifting mechanism includes an electric push rod 10, with the push rod of the electric push rod 10 vertically upwards, and a support plate 3 located at the end of the push rod of the electric push rod 10. The receiving cavity 12 also houses a battery and a PLC controller, with the PLC controller electrically connected to both the battery and the electric push rod 10. Users can control the lifting and lowering of the electric push rod 10 via remote commands or preset programs, thereby driving the monitor 5 to the optimal observation height, effectively avoiding obstructions and adapting to different monitoring distances.

[0024] Specifically, the lower end of the rectangular positioning frame 4 is provided with multiple telescopic rods 9, and the inner wall of the receiving cavity 12 is provided with a guide plate 93. The telescopic rods 9 slide through the guide plate 93, and a limiting ring 94 is provided on the outer side of the telescopic rods 9. A second spring 95 is sleeved on the outer side of the telescopic rods 9, and the second spring 95 is located between the guide plate 93 and the limiting ring 94. The telescopic rods 9 include an outer rod 91 and an inner rod 92 that is slidably disposed inside the outer rod 91. The limiting ring 94 is disposed on the outer side of the outer rod 91. The outer rod 91 is slidably engaged with the guide plate 93. The second spring 95 is located on the outer side of the outer rod 91, and the upper end of the inner rod 92 is fixedly connected to the lower end of the rectangular positioning frame 4. The inner side of the outer rod 91 is provided with a sliding groove 911, and the lower end of the inner rod 92 extends into the sliding groove 911 and is provided with a sliding plate 921 that slidably engages with the sliding groove 911 at its end. A retaining ring 912 is bolted to the upper end of the outer rod 91. It should be noted that the parts not described in detail in this application are all prior art.

[0025] During ascent, the electric push rod 10 drives the rectangular positioning frame 4 to rise, and the inner rod 92 moves upward along the slide groove 911. When the sliding plate 921 abuts against the retaining ring 912, the inner rod 92 will drive the outer rod 91 to move upward together. At this time, the second spring 95 is compressed, effectively avoiding the impact force on the monitor caused by sudden ascent. When encountering a rockfall, the electric push rod 10 can drive the rectangular positioning frame 4 to descend until the support plate 3 completely falls into the receiving cavity 12. At this time, the upper surface of the first protective plate 7 is flush with the upper surface of the protective box 1, thereby effectively protecting the monitor 5 from damage.

[0026] In addition, the upper surface of the protective box 1 has an inclined surface 11, the angle between the inclined surface 11 and the horizontal plane is 30-35 degrees, and the second protective plate 8 has two guide inclined surfaces 81, the angle between the guide inclined surfaces 81 and the horizontal plane is 20-25 degrees. This facilitates the diversion of rainwater and gravel, preventing them from accumulating on the upper part of the second protective plate 8.

[0027] Of course, this utility model is not limited to the embodiments described above. Several other embodiments based on the design concept of this utility model are also provided below.

[0028] For example, in other embodiments, unlike the embodiments described above, there are at least two protective enclosures 1, and the monitor 5 is a total station. The total station is installed on the upper end of the support plate 3 of one protective enclosure 1, and a surveying prism is installed on the upper end of the support plate 3 of the other protective enclosure 1. By using the total station in conjunction with the surveying prism to collect measurement data, mine displacement can be detected in a timely manner, avoiding safety accidents caused by mine displacement and improving the safety and stability of mine production.

[0029] For example, in other embodiments, unlike the embodiments described above, a high-precision mine reference station, a displacement monitoring station, and a server are also included. Both the high-precision mine reference station and the displacement monitoring station are equipped with high-precision GNSS receivers and are connected to the server via a local area network. The high-precision mine reference station is fixedly installed at a known coordinate location with a solid foundation within the mining area; the displacement monitoring station, consisting of a monitor and a protective enclosure, is deployed in the area where the displacement to be monitored.

[0030] When network conditions permit, the GNSS receiver accesses the local area network (LAN) via a wired transmission network; in areas with limited network conditions, it connects to the LTE base station via a customer pre-installed device (CPE) and accesses the LAN via a wired transmission network to achieve wireless network communication.

[0031] The server receives monitoring data from high-precision benchmark stations and displacement monitoring stations in the mine, performs error correction based on the known coordinates of the benchmark stations, calculates the high-precision positioning information of the displacement monitoring stations, and then analyzes their absolute displacement, displacement velocity, and acceleration, issuing early warning signals when necessary. It may also include a client connected to a local area network, allowing authorized users to receive early warning information and view monitoring data.
