SWJ-V隧道收敛计的技术性能

摘要

SWJ-V隧道收敛计是在SWJ-IV隧道收敛计基础上开发的首款PDA型收敛计，系通过无线PDA和光电控制技术开发研制的一种能自动准确控制加载、自动读数和记录的盲读型收敛计产品，可解决现有收敛计加载不准确和人工记录不便、数据不能和计算机连接的缺陷，实现用PDA记录和精准操控设备的快捷量测作业。精度评定显示，SWJ-V收敛计的量测不确定度达到了建筑变形的特级精度水平。%The SWJ-V convergence gauge, the first PDA-type convergence gauge developed based on the SWJ-IV convergence gauge, is an automatic measuring product developed using wireless PDA and photoelectric control techniques that features automatically controlled loading and automatic reading and recording. This convergence gauge overcomes the defects of inaccurate loading, the inconvenience of manual recording, and the lack of connection between data and the terminal of the existing convergence gauges, thereby achieving PDA recording and rapid measurement with accurate controlling devices. Accuracy assessments show that the certainty of the SWJ-V convergence gauge reaches a premium level regarding building deformation.
