Description

Technical field[0001]The present invention belongs to the field of engineering monitoring, and specific relates to a deep level displacement automation monitoring device.Background technique[0002]Deep horizontal displacement monitoring is a method of measuring the horizontal displacement change of the soil, which utilizes the angle change amount between the sciped tube axis and the lead profile induced by the sensor, from the bottom of the tube Point is at the point, and the level displacement of each depth point of the unearth is accumulated. Put the deep horizontal displacement sensor into the tube in the tube, the length of the slope sensor is L, measure the angle of the slanting tube axis and lead vertical line by segmenti，According to the depth of the measuring point, the angle between the different elements shall be measured separately, thus converting the horizontal displacement increment δ of different elements.i= Lsin θi. The first measured value as the initial value of the...

Problems solved by technology

[0003] At present, the monitoring of deep horizontal displacement is mainly implemented by manual monitoring, and the main problems of manual monitoring are as follows: First, it is time-consuming and labor-intensive to perform a complete manual measurement of deep horizontal displacement, including a lot of repetitive work; second, the measurement accuracy It is greatly affected by human factors, and the measurement error caused by subjective factors is relatively large; third, in some dangerous areas, it is difficult to implement deep horizontal displacement monitoring; fourth, the forward and reverse sides of the deep horizontal displacement sensor cannot be automatically controlled, and the error of gravity acceleration is difficult to eliminate
