Abstract:

Based on the phaseshift laser ranging principle, a smart tunnel laser convergence gauge was developed which consisted of a main engine, an adjusting device and the postprocessing software. The main engine has the functions of measurement, editing, calculation, and data transmission with enough memory to store monitoring data, and can encrypt the monitoring data to prevent data fraud. The adjusting device can be installed and disassembled quickly and easily. It can adjust the laser point to aim at the target accurately. Postprocessing software can process the encrypted monitoring data, draw convergencetime curve and generate reports automatically. The laboratory and tunnel onsite precision tests indicate that its monitoring precision can reach 0.50 to 0.68 mm when the length of the tunnel convergence line is within the range of 5.0 to 14.0 m. Compared with traditional convergence gauges and total stations, the smart tunnel laser convergence gauge has the advantages of high efficiency, low labor intensity and easy operation.
