AI Technical Summary
In the existing technology, the detection method of PCCP steel cylinder socket has problems such as low measurement efficiency, accuracy depending on the operator, and insufficient accuracy of automated detection. In particular, it is difficult to achieve high accuracy in measurement results caused by pixel accuracy and edge recognition errors.
It employs a combination of low-precision coarse positioning and high-precision precise measurement, using high-precision and low-precision laser sensors in conjunction with a laser protection zone and a rotating worktable to achieve precise measurement and positioning of the socket diameter. It is equipped with a control unit for data analysis and control.
This technology enables high-precision measurement of the socket diameter of PCCP steel cylinder pipes, improving the accuracy and versatility of the measurement, ensuring the convenience and safety of operation, and reducing testing costs.
