中文摘要：

针对高应力作用下巷道变形破坏会阻断交通的问题,本研究致力于开发设计一种基于激光测距仪的巷道变形测量装置。通过加入显示器、激光发射器和激光接收器能够对巷道的侧壁进行实时的检测并直接的将测量结果显示出来。装置以STM32单片机为核心,配合激光脉冲计数器原理,便于测量人员对数据进行计算,并将数据进行收集汇总。最后通过测量实验结果显示：测量10-200米的不同长度的巷道变形过程中,变形处的测距误差在0.3m以内,变形度绝对误差在24 mm。因此,本实用新型巷道变形测量装置结构简单,测量所得数据误差小,适合推广使用。

英文摘要：

Based on the deformation and failure will block traffic problems roadway under high stress, the present study is to develop designs based on laser rangefinder roadway deformation measuring device. By adding a display, a laser transmitter and laser receiver capable of side walls of the tunnel in real time to detect and direct measurement results are displayed. Means STM32 microcontroller core, with laser pulse counter principle, easy to measure personnel data is calculated, and the data collected summary. Finally, the measurement results show： measuring 10-200 meters, different lengths of roadway deformation process, deformation ranging error at less than 0.3m, the degree of deformation absolute error in 24 mm. Thus, the utility model roadway deformation measurement simple structure, the measured data error is small, suitable for promotion use.
