A concrete sample witness sampling system and method based on two-dimensional code and image recognition anti-counterfeiting

Abstract

The invention discloses a concrete specimen witness sampling system and method based on two-dimensional code and image recognition anti-counterfeiting, comprising a two-dimensional code and a positioning label for uniquely identifying a pair of embedded concrete specimens, Witness sampling and supervision personnel scan the two-dimensional code through WeChat client, and upload photos of witness and sampling personnel, photos of concrete specimen, current position information, photos of two-dimensional code on concrete specimen, photos of two-dimensional code and positioning label on concretespecimen to the cloud server data center. The three cameras upload their respective videos to the cloud server data center to monitor the testing process of concrete specimens. The cloud server data center compares the received video and pictures, identifies the concrete specimen for anti-counterfeit, and feeds back the identification results to the WeChat client and the witness sampling supervision and management platform. The invention can guarantee the traceability of each link and the authenticity of the witness sampling and the concrete test piece.

Description

technical field [0001] The invention relates to the technical field of witness sampling of concrete test pieces during on-site construction, in particular to a system and method for witness sampling of concrete test pieces based on two-dimensional code and image recognition anti-counterfeiting. Background technique [0002] Witness sampling is an important means of project quality supervision and construction quality control, plays an important role in construction project quality supervision, and is the primary link to ensure the fairness, scientificity and authority of construction project quality inspection work. However, in the actual operation process, due to the disconnection between sampling and witnessing, the samples are underrepresented, distorted, or even faked, which deviates from the true level of structural entity quality. The representativeness and authenticity of the samples are relatively common problems, resulting in the data in the inspection report not be...

AI Technical Summary

Problems solved by technology

One is to implant the two-dimensional code label when the concrete specimen is finished. After the witness sampling is completed, the maintenance within the specified period is carried out, and then the test is carried out. During this process, the two-dimensional code label may still have the problem of replacement, resulting in the final test result. there is fraud

The second is to use the corresponding two-dimensional code scanning device to identify the two-dimensional code when doing the compression test on the concrete specimen submitted for inspection, and the corresponding information will be entered into the cloud server and then compared with the witness sampling information. It can be scanned at will, so untrue information may also appear in the process, resulting in falsification of the final test results
