Abstract
The necessity of using real-time monitoring is analyzed
in the course of construction of bias deep foundation pit.The component of the long-range real-time monitoring and early warning system is introduced.The system consists of three parts
which are data collection
transmission and processing.Bus-type connection is used between the sensor and data acquisition instrument
and GPRS is used to transmit data between the data collection instrument and the host computer.The function of software data processing is strengthened
which can directly calculate the bending moment.The layout plan of sensors is described
and examples of measurement results are also given.Practice shows that the system can complete on-site monitoring very well.
