Electric power angle steel intelligent detection system and method based on image recognition

Abstract

The invention discloses an electric power angle steel intelligent detection system and method based on image recognition. The detection system is arranged at an angle steel finished product end on the premise of not changing an angle steel processing line, and the detection system comprises a main body support, an image sampling device, an angle steel sensing device and a detection control system; the main body support is a doorframe-shaped support; the image sampling device and the angle steel sensing device are installed on the main body support, the angle steel conveying device penetrates through the main body support, and the image sampling device includes two sets of industrial linear array cameras and is used for sampling two right-angle faces of angle steel; the angle steel sensing device comprises a photoelectric sensor and an encoder, the photoelectric sensor is used for detecting the conveying position of angle steel, and the encoder senses the angle steel conveying speed and controls the camera shooting frequency; and the detection control system judges and displays angle steel processing results. The device is independent of an original angle steel processing equipment production line, and the original angle steel production line is not transformed while intelligent angle steel detection is achieved.

Description

technical field [0001] The invention relates to the technical field of angle steel intelligent detection, in particular to an image recognition-based electric power angle steel intelligent detection system and method. Background technique [0002] Transmission line tower is a tower-shaped building for power transmission. Their structural characteristics are that all kinds of towers are space truss structures. The rods are mainly composed of single equal-sided angle steel or combined angle steel. The connection between the rods is connected by bolts. The performance quality of the key components of the power tower is directly related to the safety and reliability of the power grid operation.

AI Technical Summary

Problems solved by technology

[0003] At present, the iron tower manufacturing industry mostly uses angle steel processing lines to complete the processing operations such as marking, punching, and cutting of raw materials. Large, easy to miss inspection, resulting in economic losses; manual measurement and inspection of geometric parameters such as angle steel product length, hole diameter, hole spacing, hole number, etc., is highly subjective and difficult to operate.

At present, some units are piloting to use cameras to sample and measure multiple geometric parameters of angle steel. However, in the design process, the transformation of specific angle steel processing and production equipment has changed the original equipment structure. This method is costly and has poor versatility. The conditions for popularizing and applying the area; in addition, the scientific research institute proposed that the 3D scanner adopts the method of splicing targets for 3D modeling, but the cost of the solution is too high to meet the actual needs of the enterprise's equipment cost, and there is no specific online detection solution for this solution
