In-Place Inclinometer

The In-Place Inclinometer module takes the data from a selection of inclinometers (bi-axial tilt sensors) and computes from the sum of individual lateral offsets a total deflection value. An in-place inclinometer is a type of a geotechnical sensor. For measuring the total deflection value it is necessary to have installed a series of inclinometers.

Prerequisites

The In-Place Inclinometer module depends on the tilt data to be available in angle values within the Trimble 4D Control Server system. It does not collect the data from the sensors itself. For collecting the tilt data of a tilt sensor and forwarding it to the In-Place Inclinometer module, one needs the previous setup of at least one Data Logger module. The Data Logger module, representing a physical data logger being attached to Trimble 4D Control Server extracts the tilt data from data logger data files and performs quality control checks on it. It writes the data into the monitoring database and makes the data of selected tilt sensors available to the In-Place Inclinometer module.

Using the total deflection value when monitoring High Rise structures

One may use the processing result of the In-Place Inclinometer module as one of several methods when monitoring high rise structures such as tall buildings during construction. To do so, one sets up a Trimble 4D Control Server High Rise module, which delivers precise and reliable coordinates on demand which one can use to position a total station on such a high rise structure, for using the total deflection value resulting from an In-Place Inclinometer module additionally to the GNSS positions and total station corrections.

Adding the module

The In-Place Inclinometer module is available from the Tree view root Trimble 4D Control Server. Trimble 4D Control Server accepts multiple In-Place Inclinometer modules in the system.

When the module is being added, the In-Place Inclinometer Properties dialog appears. It lets you configure the In-Place Inclinometer module to the physical Data Logger being attached to Trimble 4D Control Server. Each instance of the In-Place Inclinometer module (that is, each configuration) represents a set of in-place inclinometers that will be used to compute one total deflection value of the object they are attached to. Additional to the selected set of inclinometers, a configuration holds information on a timeout threshold. You also may remove a configuration from here, if you do not need it anymore.

Data visualization

Once configured, the In-Place Inclinometer module provides collective information about the status of each inclinometer and its respective data acquisition. Through the view available to this module, one can additionally quickly determine the total deflection value of the observed object.

In the Tree view, each In-Place Inclinometer module is represented by its configuration name and a status-identifying icon.
