Study on On-line Control and Measurement of Foundation Trench-leveling System
Research the system software and hardware composing, the control mode, the on-line measurement and control principle based on the laser receiver and the inclination sensor as the signal source. After the laser receiver accepts the laser signal, the laser signal is carried through the light filter treatment so as to reduce the sunlight interference, and then amplified and modulated, last transmitted to the control unit. The inclination sensor the model number of which is XWQJ02-01S measures the slope angle of the x and y verticality direction. The error adjusting range is ±0.05°. The separate time treatment avoids simultaneously adjusting the laser and inclination signal to each other interfere. The on-line measurement and control system realizes the parts to work on the plane that parallels with the datum plane of the laser beam scan. The working parts must retain ±0.05°with the datum plane. Adapting the least square method to fit the linear curve, the movement trend of the work parts on the work plane is judged through the slope direction. The test result shows that thought the combination measurement and control of the laser and slope angle the leveling precision are ±5mm/100. Its can satisfy with the construction criterion request.
