A device for obtaining the location of buried pipelines based on encrypted two-dimensional code recognition

Abstract

The present invention belongs to the buried pipeline detection technology field, and especially relates to a device and method for obtaining the position of a buried pipeline based on encrypted two-dimensional codes. The device comprises a two-dimensional carrier, and a metal protective housing and a metal protective cover which are arranged at the outer layer of the two-dimensional carrier. The upper surface of the two-dimensional carrier is engraved with encrypted two-dimensional code patterns which store the position information of the buried pipeline to effectively ensure the safety and the privacy of the buried pipeline data. There is a lot of stored information content in the two-dimensional codes, and the storage information can be still restored in the condition of damaging the part of the bar codes to ensure the integrity of the underground pipeline data; the two-dimensional codes is long in service life, can be moved with a bearing object and can be used through separating from a database and a computer network; and moreover, the data information can be conveniently and rapidly obtained in the search process.

Description

technical field [0001] The invention belongs to the technical field of buried pipeline detection, and in particular relates to a device for identifying and acquiring the position of buried pipelines based on encrypted two-dimensional codes. Background technique [0002] With the rapid development of the domestic economic level, social public service facilities are becoming more and more perfect. In the future, more underground engineering construction will be carried out in cities to benefit the people. In order to do a good job in the protection of existing pipelines and the normal operation of underground engineering processes It is particularly important for this type of project to find out the specific location and distribution of the buried depth of the underground pipelines (natural gas pipes, water pipes, electric pipes) where the project is located. However, due to the buried depth of the pipeline ranging from tens of centimeters to several meters, the buried depth l...

Problems solved by technology

[0004] However, the above-mentioned methods have certain disadvantages. For example, due to the differences in functions of each buried pipeline, they belong to different management departments, involve many units or departments, and the construction time of buried pipelines is long, so it is impossible to ensure that comprehensive information can be obtained accurately; and using During the detection process of detection equipment such as metal detectors, detection radars, and geological radars, they are susceptible to interference from underground non-target pipelines. At the same time, the operation of measuring instruments is complicated, and the long-term burial of underground pipelines may reduce the detectability of pipelines. Affect the detection effect, resulting in a large error in the detection results, and it takes a lot of manpower and financial resources

In addition, with the increase in the number and functionality of buried pipelines, there are more challenges for pipeline maintenance and emergency repairs, which require quick processing and real-time response, and the traditional line-finding method will inevitably greatly affect its actual construction.
