Use of accelerometer sensors to measure the states of retaining steel networks and dynamic barriers

摘要

The paper deals with the use of accelerometer sensors for measuring the states of retaining steel networks and barriers. It is discussed a design of the measuring chain for monitoring the state of these protective devices and its individual components are described. For transferring data from accelerometers to a superior system, IQRF technology is used to communicate between wireless nodes and network coordinator in the MESH topology. An integral part of the article is a description of two pilot experiments and evaluation of the measured data.
