2.2 Testing Principle

The instrument will generate the pulsed magnet field via high-current excitation transmitting coil. In case of rebar being detected underneath the magnetic field, therebarwillproducetheturbulenceattheexcitationofpulsedmagnetfield,and then make an induced magnetic field. The receiving coil will convert the induced magnetic field to an electrical signal. The main machine performs real-time analysis of the electrical signal, and then identify the location of rebar, concrete cover depth and diameter. The receiving coil is configured in a multiple set of coil combination,thusyieldingthehighertestingaccuracyagainstthetraditionalcoil testinginasingleway.

3 Operation Description

3.1 System Overview

LR-G200 Integrated rebar scanner system is designed to assure indication of each function menu, instrument status, measurement data and result. The man-machine interaction for the entire system is achieved through the key and touch units, whichiseasiertooperatethanthetraditionalsimplekeyoperation.

ComponentNo.

The component no. consists of digit, letter and symbol. The user can set a component no. in max. 12 digits and min. 1 digit. The user may carry out setting wheneverrequired,asdetailedbelow:

Move the cursor to the desired component no. Press OK key or directly touch thefieldtogotothecomponentno.editstatus.Now,asoftkeyboardwillappear in the bottom of screen.

3.2.1.2 Quick scanning

In the quick scanning interface, slowly move the trolley at constant speed to the right to start measurement. When the trolley approaches the rebar, a green aiming box appears. Now, slowly move the trolley while the aiming box slowly approaches the centerline. When the aiming box completely fits the centerline, theaimingboxturnsouttoberedandtheredlightgetslit,plusbeepsoundbeing heard. The laser light in front of the instrument will emit a red line,indicating that the instrument has detected the rebar, right below the red line. In case of automatic storage mode being set, automatic storage is performed to assess the concrete cover depth. In case of manual storage mode being set, press FN key to save the depth value, which appears in the bottom of screen. When the trolley movesfarfromtherebar,theaimingboxgetsawayfromthecenterline.Whenthe aiming box moves beyond the e ective range of detection, the aiming box returnsbacktothecenterline,highlightedingrey.Whenthetrolleystaysbetween tworebars,theaimingboxisinblue.

Continue to move the trolley to the right for detection of next rebar. The same hintwillappearintheinstrument.Now,theconcretecoverdepthanddistanceto the previous rebar will appear simultaneously. As illustrated in Fig.3.4, the concretecoverdepthisnow11mm,concretecoverdepthforthepreviousrebar
