The array displacement sensor is installed in a geological disaster area to be monitored. The geological disaster area to be monitored is provided with a drilling hole or an embedded structure to place and install the array displacement sensor. The array displacement sensor is connected to the MCU, and the array displacement sensor transmits monitoring data to the MCU. The LORA communication module is connected to the MCU, and the LORA communication module transmits data in the MCU to a user end.

[0031] In this embodiment, the array displacement sensor includes multiple continuous sections connected in series, the interior of the continuous section is composed of a micro-electromechanical system MEMS accelerometer, the length of the continuous section is 30cm-50cm, and the embedded structure includes a pre-buried steel pipe 6 and an omnidirectional tube 7. The omnidirectional tube 7 is composed of multiple segments corresponding to the continuous section.

[0032] The basic principle of the array displacement sensor is that by detecting the gravity field of each part, the bending angle θ between each segment of the shaft can be calculated. Using the calculated bending angle and the known length L (30cm or 50cm) of each segment of the shaft, the deformation Δχ of each segment can be completely determined, that is, Δχ=θ·L. Then, the arithmetic sum ∑Δχ of each segment can be obtained to obtain the deformation χ at any length from the fixed end point, such as Figure 4 and Figure 5 .

The embedded steel pipe 6 is tied and fixed on the steel cage. The position should be as close to the center of the wall as possible, and fixed vertically as possible to keep parallel to the wall. After the construction of the underground continuous wall is completed, the overall length of the omnidirectional pipe 7 and the length of each segment are determined according to the on-site conditions. The sections of the omnidirectional pipe 7 are waterproofed, assembled on site and inserted into the detection channel to form a whole with the underground continuous wall. Then the mounting frame and its upper equipment are installed and connected, and the equipment is started to check whether it is normal; initialization and calibration are performed, and the equipment is set to operate normally, and the monitoring accuracy is ±0.5mm for settlement observation and ±0.5mm for horizontal displacement observation.
