Abstract
With aim to deal with a continuously environmental change that may be unknown at design-time, we have proposed a novel self-adaptive data acquisition method for slope instability monitoring. The developed device can automatically adjust its data output rate from very low frequency to high one to capture the high-speed process when the physical variable sensed is dramatically changing. Such technique has the potential to reduce the energy consumption, bandwidth resources and data transmission burden in some practical energy conservation monitoring applications. A preliminary application of the proposed method was successfully carried out in one slope monitoring engineering in China. Application results indicate that the suggested solution can save much more energy consumed, while maintaining the data quality of crucial information.
