A concrete test block encryption method and device

Abstract

The invention discloses a concrete test block encryption method, comprising the following steps: detecting a first magnetic field strength at a preset position of a first encrypted concrete test block, and generating encrypted information based on the first magnetic field strength; The second magnetic field strength at the preset position of the second encrypted concrete test block generates decrypted information based on the second magnetic field strength; matches the decrypted information with the encrypted information, and if the matching is successful, then determine the The first densified concrete test block and the second densified concrete test block are the same densified concrete test block. At the same time, a concrete test block encryption device, an encryption information generation module, a decryption information generation module, a matching module and a determination module are also proposed. The beneficial effects of the invention are: not only can the concrete test block be encrypted to prevent the test block from being packaged, but also the encryption method is simple and fast.

Description

technical field [0001] The invention relates to the field of construction engineering, in particular to a concrete test block encryption method and device. Background technique [0002] The test blocks participating in the concrete strength evaluation are divided into standard culture test blocks and co-culture test blocks. The standard culture test blocks refer to the test blocks cured in the standard culture room. The specification stipulates that the standard culture test blocks are in the temperature range of 20±2℃, humidity More than 95%, curing for 28 days; co-culture test block refers to the test block made of randomly selected concrete at the pouring site, and the co-culture test block is randomly selected at the construction site and accumulated at the site according to the site maintenance conditions The daily average temperature reaches 600 degrees Celsius test block. At the same time, the "Construction Quality Acceptance Code for Concrete Structure Engineering" ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, in the actual implementation, when the inspection party submits the standard curing test block and the same condition curing test block for inspection, it is easy to switch the standard curing test block and the same condition curing test block, resulting in false detection data and making government supervision Failure, cannot truly reflect the quality of the project
