Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to an inclination and settlement integrated monitoring sensor. Background Art

[0002] Real-time monitoring of the horizontal displacement of underground landslides is crucial in areas such as geological disaster monitoring, dam displacement monitoring, and infrastructure safety assessments. While effective in some situations, traditional manual inclinometers and fixed inclinometers suffer from issues such as poor real-time performance, susceptibility to human error, and reliance on external power sources. These shortcomings prevent monitoring efforts from responding to potential risks in a timely manner, increasing the likelihood of accidents. Currently, there are many systems for surface displacement monitoring, such as slope displacement meters and GPS measurement systems, which offer good accuracy and stability. However, due to the inherent characteristics of high slopes, deep foundation pits, and tailings dams, deformation may begin from internal displacement. Surface displacement monitoring cannot monitor internal displacements in the rock and soil, rendering it ineffective for monitoring high-risk geotechnical engineering projects.

The standard MODBUSRTU protocol can be used for data uploading, and it can also be adjusted according to the requirements of the on-site transmission protocol.

[0031] In addition, in the embodiment of the present invention, the inclination measuring device, the settlement collecting device, the temperature sensor and the data collecting and processing terminal are all connected to the connecting cables, thereby realizing data transmission and power supply.
