Embodiment Construction

[0029] Detailed descriptions of well-known functions and constructions of the present invention will be avoided herein so as not to obscure the true purpose of the present invention. Terms described below are defined according to the functions of the present invention. The meanings of these terms may vary depending on the user, operator's intention, usage habits, etc. Therefore, terms defined according to these descriptions are not limited to this specification.

[0030] Among short-range wireless communication technologies, Bluetooth technology operates within a short distance, while WiFi technology has a wider bandwidth but has a heavier load. A WiFi network is a short-range communication network using radio or infrared communication, which is commonly referred to as a Wireless Local Area Network (WLAN). Wireless communication is exposed to noise, and noise interference becomes a challenging problem in the field of wireless communication. Therefore, the present invention ...

Abstract

A non-destructive inspection apparatus for detecting an internal defect in a concrete structure using ultrasonic waves is provided, in which a transmission probe and a reception probe are injected into tubes within a concrete pile, a pulley is connected to the transmission and reception probes by a cable, a drum is connected to the pulley, includes a drum controller, receives data from the transmission and reception probes and the pulley, and conducts wireless communication, and a main body receives a signal from the drum controller of the drum and conducts wireless communication by ZigBee.

Description

technical field [0001] The present invention relates to a non-destructive testing device for detecting internal defects of concrete structures using ultrasonic waves, especially a non-destructive defect testing device for determining whether there is a defect in the homogeneity of the interior of concrete, for example, about 100 meters for a transmitting probe and a receiving probe long pillars. Ultrasound can be used to determine the presence or absence of flaws in concrete and the strength of concrete. By applying ultrasonic waves to a target object and measuring the intensity and position of the reflected waves from the target object, it is possible to determine the presence or absence of defects in concrete and the size of that concrete. Background technique [0002] [Reference 1] Korean Patent No. 10-0478105 (March 11, 2005); [0003] [Reference 2] Korean Patent No. 10-0439334 (June 28, 2004); [0004] [Reference 3] Korean Patent No. 10-0685178 (February 14, 2007); ...
