Embodiment Construction

[0059] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0060] Such as figure 1 Shown is a structural block diagram of the crack detection system of the present invention, wherein the system includes a crack sensor 2 installed on the component to be detected 1 and a wireless detector 3 connected to it in communication, wherein the wireless detector 3 is configured to detect cracks The sensor 2 sends electromagnetic waves to send an inquiry signal and electric energy to it, and judges whether there is a crack on the component 1 according to whether it receives a reply signal corresponding to the inquiry signal. In addition, the crack sensor 2 is configured to detect whether there is a crack on the component 1, and when it detects that there is no crack on the component 1, send a reply signal corresponding to the query signal to the wireless ...

Abstract

The invention discloses a crack detecting system which comprises a crack sensor installed on a component to be detected, and a wireless detecting instrument in communication connection with the crack sensor. The wireless detecting instrument is configured to send electromagnetic waves to the crack sensor so as to send inquiring signals and electric energy to the crack sensor, and whether cracks exist or not is judged according to whether the wireless detecting instrument receives response signals corresponding to the inquiring signals or not. The crack sensor is configured to detect whether cracks exist on the component or not, and when it is detected that no crack exists on the component, the response signals corresponding to the inquiring signals are sent to the wireless detecting instrument. When it is detected that the cracks exist on the component, no signal is sent to the wireless detecting instrument. The crack detecting system has the advantages of being convenient to install and high in detecting precision and needing no external power source.

Description

technical field [0001] The invention relates to the field of structural crack detection, in particular to a crack detection system and a detection method thereof. Background technique [0002] At present, the following technologies and methods are usually used for structural crack detection at home and abroad: [0003] 1. Liquid penetration method Penetration testing (PT) is to coat the metal surface with a certain kind of penetrating colored liquid. After wiping, the cracks can be displayed due to the liquid remaining in the cracks. It is mainly used for the detection of casting / forging parts. [0004] 2. Magnetic particle method Magnetic particle detection (MT) uses fine particles of magnetic powder. When they enter the leakage magnetic field caused by cracks, they will be attracted and left behind. Since the leakage magnetic field is wider than the crack, the accumulated magnetic powder can be detected by naked eyes. easy to see. Commonly used in the detection of casti...
