摘要:
针对传统位移监测传感器布线多、安装调试维护复杂以及不能实现动静一体化监测问题,研制了一种基于机器视觉的水闸一体化监测系统。系统采用嵌入系统、双光摄像头结合机器视觉技术,通过采样频次可调可以获得不同频次的水闸表面位移,最高采样频率达到60 Hz,能满足昼夜连续工作需要。现场实测数据显示系统能精准感知由于外界荷载变化导致的水闸动态变化,测值符合水闸变形规律。研究表明,本系统安装调试维护方便,可在其他直线型长度不超过400 m的水工建筑物工程中推广应用。
Abstract:
Aiming at the problems that traditional displacement monitoring sensors have many wiring, complex installation, commissioning and maintenance, and can not realize dynamic and static integrated monitoring, a sluice integrated monitoring system based on machine vision is developed. The system adopts embedded system, dual light camera and machine vision technology. Through the adjustable sampling frequency, the sluice surface displacement with different frequencies can be obtained, and the maximum sampling frequency can reach 60 Hz, which can meet the needs of continuous work day and night. The field measured data show that the system can accurately perceive the dynamic change of the sluice caused by the change of external load, and the measured value conforms to the deformation law of the sluice. The research shows that the system is easy to install, debug and maintain, and can be popularized and applied in other hydraulic structures with linear length less than 400 m.
