摘 要: | 研制了一套全新的自动安平机构,以解决传统激光扫平仪无法同时兼顾安平精度、范围和速度的问题。首先,改进了传统自动安平仪器中的倾角传感器,设计了一种带有补偿环节的电子水泡以满足仪器的精度要求;其次,基于PID控制方法设计了用于实现仪器自动安平的闭环控制系统,同时引入模糊控制思想,使其达到了仪器自动安平的速度要求;最后,优化了仪器机械结构,有效增大了仪器的安平范围。实验测试结果表明,该扫平仪在-10°~+10°的安平精度达到10″,且自动安平时间小于10s。传统的激光扫平仪相比,设计的安平仪具有安平精度高、扫描范围大和安平速度快等特点。

Fast automatic rotating laser construction based on fuzzy control |

Abstract: | As traditional rotating laser construction can not give all considerations to the speed, range and the precision of leveling, this paper developed a new self-leveling mechanism to solve the problem above mentioned. Firstly, by improving the angle sensor in a traditional rotating laser construction, a kind of electronic bubble with the compensative function was designed to meet the accuracy requirement. Then, based on the PID controlling method, a closed loop control system for the self-leveling was designed, while the fuzzy control method was induced to the index of leveling speed. Finally, the general layout of the system was optimized, and the range of self-leveling was enlarged. The experimental result indicates that the leveling accuracy is 10″ and the leveling time is less than 10 s while the inclining angle is from -10° to +10°. In conclusion, the new construction has the characteristics of higher leveling precision, larger leveling ranges and faster leveling speeds as compared with the traditional one. |
