Abstract
In regards to such problems as low degree of automation, reading data out of time, and low measurement precision when monitoring soft-soil ground settlement in our nation at the present time, we put forward a research approach for a new automatic monitor for soft-soil ground on the basis of draw-wire displacement sensors and collimating of wireless triggering. In the paper, we discuss the surveying scheme, embedded system design, and the confirmation of collimating fault of wireless triggering. Finally, some technical parameters are gained via the experiment of surveying comparison: linearity is 0.235%; sensitivity is 1.0049; sensitivity error is 3.45%; the resolving power is 0.25mm; the scale of measurement is 0-10m.
