摘要 基于扫平仪自动安平的原理,设计了一种电子水泡水平传感器,并采用分段P调节的控制思想,研发了一套合适的控制方法,实现了扫平仪的自动安平,达到了仪器设计的精度要求.此外,还优化了激光扫平仪结构的总体设计方案,完成了仪器在较大安平范围内快速自动安平功能.并对仪器误差来源进行了分析与讨论.测试结果表明:该扫平仪在-10°~+10°的角度调整范围内达到了10″的安平精度,且自动安平时间少于15s,达到了高效率、高精度的设计要求. Based on the principle of self-leveling in rotating laser, a sensor named electrical bubble was designed. An appropriate controlling system was developed to make sure the index of the accuracy. The integral design of the system was optimized, so the fast automatic leveling in a large range has been come true. Lastly, the general test method of the rotating laser was pointed out and the source of errors in this instrument was discussed. The testing results show that the instrument has a precision of 10" in the range that from --10°~+10°, while the time of self-leveling is less than 15 s. So the in- strument reaches the requirement of high efficiency and precision.
