Description

technical field

The invention relates to the field of monitoring systems, in particular to an intelligent traction type deep level displacement monitoring system based on an automatic lift inclinometer.

Background technique

Inclinometer is a monitoring instrument used to monitor the apex angle and azimuth angle of geotechnical structures such as foundation pits, foundations, walls and slopes. It can obtain the horizontal displacement of the soil layer by measuring the inclination angle of the borehole. Changes have played an important role in ensuring the safety of geotechnical engineering design, construction and use.

The principle of the fixed inclinometer is: a gravitational accelerometer, which measures the component of the earth's gravity in the measurement direction. It can measure the inclination changes in both X/Y directions at the same time, so that the inclination direction and inclination angle of the point can be obtained through calculation; it can be directly connected to the bus system for automatic data collection. If the measurement range is small, the measurement accuracy is required to be high, and the high-precision electronic inclinometer is used.

It is widely used to observe the changes in the horizontal direction inside the soil such as mountain slopes, earth-rock dams, seaside embankments and building foundation pits. It has changed the way that portable inclinometers must be monitored manually; wireless automatic monitoring can be realized for remote areas; it is a necessary precision measuring instrument for projects such as ports, railways, highways, and high-rise buildings.

The current fixed inclinometer has the following shortcomings: (1) the current fixed inclinometer is limited by the sensor spacing and the connector device cannot measure the deformation state of the entire underground measuring pipe; (2) the current fixed inclinometer In the process of installation and debugging of the inclinometer, the sensors need to be put into the tubes one by one, and connected with connectors one by one, the installation process is more complicated, and the measurement accuracy is low; (3) the existing technology of the fixed inclinometer needs to be wired. External external power supply, external communication device, and supporting equipment are complicated. In case of line failure, it needs to be re-installed and debugged; (4) During the measurement process, in case of sensor failure, the replacement needs to take out all sensors and components and replace them again. The data will be poorly connected and need to be recalculated, resulting in unavoidable precision errors.
