摘　　要：基于激光三角法检测原理,研制出了在较恶劣的工作环境下的多对象高精度液位巡检系统。该系统利用液体连通器液位等原理,将检测系统与工作区域分离,通过激光位移传感器取液位信号,经过应用LabVIEW技术的上位机软件分析处理,可以得出液位变化情况。传感器在直线电机带动下,可以实现对12个检测对象的实时液位检测。实验表明,系统定点检测的误差率小于±0.6%,12路重复测量误差不大于±0.05mm,具有良好的实际应用效果。Based on the principle of laster triangulation measurement,a high precision liquid level inspection system for multiple objects in a relatively harsh working environment was developed.The system used the liquid communicating vessel liquid level of high principle,separation of the detection system and the work area,obtaining liquid level signal by laser displacement sensor,through the computer software application LabVIEW technology analysis,can draw the liquid level changes.Sensors in the linear motor drive,can realize the real-time level on 12 object detection.Experiments show that the error of the system,designated detection rate is less that ±0.6%,12 repeated measurement error is less than ±0.05 mm,has a good effect in practical aplication.
