Wall body detection system and method based on smart phone

Abstract

The invention discloses a wall body detection system based on a smart phone, which comprises the smart phone with a loudspeaker, a microphone, an acceleration sensor and a detection processor, and a coupling structure, wherein the loudspeaker has an audio playing function, and an acoustic wave S0 of a certain frequency is generated; an acoustic wave S generated by reflecting the acoustic wave S0 by a hollow structure is received by the microphone; a change position L obtained after the phone moves is detected and recorded by the acceleration sensor; the coupling structure is closely attached between the smart phone and a detected wall body, and is used for coupling the smart phone to the detected wall body; the detection processor is used for calculating a two-dimensional image according to the acoustic wave S acquired by the microphone and the position L recorded by the acceleration sensor, and displaying the two-dimensional image on a display screen of the smart phone. The invention further discloses a wall body detection method based on the smart phone. The system has the advantages of low cost, wide application range and easy operation.

Description

technical field [0001] The invention belongs to the field of building structure detection, and in particular relates to a smart phone-based wall detection system and method. Background technique [0002] In the civil engineering and construction industry, it is inevitable to involve the quality inspection of the wall, as well as the transformation and construction of the existing wall. It is often impossible to accurately know the situation of some pre-embedded structures and pipelines in the wall during the renovation of some buildings with irregular drawings or the repair of historical buildings, which often causes some accidents and losses during construction. Therefore, before and after the construction of the wall, if the situation in the wall can be detected and obtained, it will be of great help to the construction quality and efficiency. [0003] At present, there are many products related to wall detection, such as the D-tect120 detector of BOSCH in Germany, which ...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many products related to wall detection, such as the D-tect120 detector of German BOSCH, which uses the principle of magnetic field induction and can completely detect metal parts, but the detection ability of other structures is insufficient.

At the same time, ordinary brick walls, clear water walls and concrete walls and other structures also affect its detection effect

Moreover, the biggest problem with existing products is that they can only obtain the reaction in the wall at the current position, and cannot obtain the structural image of an area. They can only be marked on the wall manually, which requires professional operation training and is expensive.
