A method for preventing replacement of concrete specimen implanted labels

Abstract

The invention discloses an exchange preventing method for a label embedded in a concrete test piece. The method comprises the following steps: when the concrete test piece is manufactured, an identification label is embedded in the test piece, and an identification part is exposed from the surface of the test piece; when the test piece is finished and not solidified, the test piece surface from which the identification part is exposed is shot, a non-solidified state picture is obtained, the non-solidified state picture and relevant shooting information during shooting are transmitted to a detection unit, and then the test piece is sent to the detection unit; after receiving the test piece, the detection unit takes a comparison picture under the same condition according to the shooting information, performs characteristic comparison on the comparison picture with the received non-solidified state picture, and determines that the test piece is effective in case of complete consistency; otherwise, the test piece is determined to be ineffective. By comparing the pictures of the concrete surface before and after inspection, better anti-counterfeiting effect can be realized, and a good promoting effect on strengthening monitoring of the concrete test piece is achieved.

Description

technical field [0001] The invention relates to an anti-replacement method for implanting labels into concrete specimens. Background technique [0002] In the field of construction, in order to supervise the quality of concrete entities, our country currently uses some concrete specimens as test pieces while pouring concrete entities, and the construction unit sends these concrete specimens to the supervision department for testing. Concrete specimens reflect the strength of the concrete entity to a certain extent, and are also the main basis for concrete quality assessment, but there are also some construction units or supervision companies that do not pay attention to the witness sampling work, the number of certified witnesses is insufficient, and the management work is not in place , and even intentionally falsified in the sampling of raw materials or the production of concrete test blocks, artificially laissez-faire to make "fake test blocks", the phenomenon that test s...

Problems solved by technology

Since it takes a long time for the concrete specimen to solidify, during the waiting period for the solidification of the specimen after the supervisor leaves the site and the specimen is submitted for inspection, there are still problems in taking out the two-dimensional code label from the original specimen and using other concrete to make fake specimens.
