Currently, traditional vertical displacement monitoring methods and equipment have many shortcomings.

[0003] Early displacement sensors, such as resistance strain gauge displacement sensors, were used in some engineering projects, but they were significantly affected by environmental factors (such as changes in temperature and humidity). Environmental changes would alter the resistance characteristics of the strain gauge, resulting in poor stability and large fluctuations in measurement data.

[0004] Therefore, we provide a high-precision vertical displacement monitoring device to address the shortcomings of existing technologies. Utility Model Content

It plots the vertical displacement change curve of the factory foundation, calculates the displacement change rate, and uses big data analysis and artificial intelligence algorithms to predict the trend of the displacement data. Once the displacement change exceeds the preset safety threshold, it immediately issues an alarm through various means such as audible and visual alarms and SMS notifications to remind factory managers and technicians to take timely measures.
