Steel bar image scanning detector

Abstract

The invention discloses a steel bar image scanning detector. The detector comprises a probe; a 480*320 dot matrix TFT color liquid crystal display is installed on the probe; a CPU and a pulse generator electrically connected with the CPU are fixed in the probe; the pulse generator is electrically connected with a pulse driver; a main coil is installed on the bottom surface of the probe; the main coil receives a pulse signal from the pulse driver and outputs the pulse signal; an induction coil for inducing the main coil is further installed in a space defined by the main coil; the induction coil is electrically connected with a detection amplifier; the detection amplifier is connected with the CPU through a multi-channel analog-digital converter; and the TFT color liquid crystal display isin circuit connection with the CPU. Compared with the prior art, the detector has the advantages that an image of steel bars buried in concrete can be intuitively displayed in real time; the depth, spacing, thickness, direction and distribution conditions of the steel bars can be intuitively displayed; and the efficiency of field steel bar detection is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of scanning detectors, in particular to a steel bar image scanning detector. Background technique [0002] There are two main types of existing steel bar detectors: [0003] The first category: the steel bar detector represented by German Hilti PS200, this product includes two parts: [0004] 1. PS200S probe: [0005] Probe structure and function: Probe 1 has four wheels 2, and every two wheels are connected by shaft 3 (as attached figure 1 , figure 2 shown). The shafts of the pair of wheels are fixed with an encoder disc 4 and pass through the gap of the photoelectric encoder 5 . The rotation of the wheel will drive the code disc to rotate, and the code strip on the code disc cuts the infrared light sent by the photoelectric encoder fixed on the circuit board 6, so that the encoder generates a pulse signal. As the distance signal of the probe movement, it is output to the CPU (central processing unit...

Problems solved by technology

[0010] In order to solve the problem that the steel bar scanning detector in the prior art cannot visually display the image of the steel bar in the concrete, the present invention provides a steel bar image scanning detector, the purpose of which is to use section scanning, and obtain the result after scanning It is the electromagnetic reflection signal of steel bars at all points on a surface. After signal processing, the real image of steel bars can be obtained, and the image of steel bars can be displayed while scanning. What you see is what you get.
