Problems solved by technology

[0003] The existing mature underwater positioning technologies at home and abroad are mainly used in marine development scenarios. The laying and recycling of positioning arrays takes a long time and costs a lot. Moreover, these methods are inefficient and weak in adaptability, and are not suitable for small and medium-sized reservoirs. dam body defect detection
[0004] The use of manned submersibles to detect reservoir dams is currently an effective means, but due to the complex underwater environment, it is extremely difficult to accurately locate the manned submersible

Abstract

The invention discloses a dam defect detection system based on mechanical wave positioning and a working method thereof. The system comprises a submersible, a vibration sensor and an information processing unit; the submersible is provided with a camera and a mechanical arm; the camera is used for observing a reservoir dam body and recording a crack image; the front section of the mechanical arm is provided with a vibration source generator; the vibration sensor is arranged on a dam to be detected and is used for acquiring mechanical waves generated when the vibration source generator knocks the dam; and the information processing unit is used for processing the mechanical wave data acquired by the vibration sensor. The dam defect detection system based on mechanical wave positioning and the working method thereof have the advantages of high positioning precision, low operation technical difficulty and wide application range.

Description

technical field [0001] The invention relates to the fields of information processing and underwater positioning, in particular to a dam defect detection system based on mechanical wave positioning and a working method thereof. Background technique [0002] There are more than 86,000 dams of various types in our country. These dams were built in different years and have different safety conditions. Due to water quality erosion and freeze-thaw damage, cracks in concrete dams are common; There have been more than 3,400 dam safety accidents, and the dam safety problems that continue to appear have seriously threatened the safety of people's lives and properties. [0003] The existing mature underwater positioning technologies at home and abroad are mainly used in marine development scenarios. The laying and recycling of positioning arrays takes a long time and costs a lot; moreover, these methods are inefficient and weak in adaptability, and are not suitable for small and medium...
