RFID application in underground pipeline marking management

The application of RFID in underground pipeline marking management is an important part of urban infrastructure, and it is also important basic information for urban planning and construction management. Urban underground pipelines include water supply, drainage (rainwater, sewage), gas (gas, natural gas, liquefied petroleum gas), telecommunications, electricity, heat, industrial pipelines, etc. They are responsible for transmitting information or transmission media. They are cities The material basis for survival and development is called the "lifeline" of the city.

新的地下管线定位和inspection and maintenance system uses RFID as a management method. It is a detection and data processing system that can meet the accurate positioning of the pipeline and reflect the actual information of the pipeline from the trenchless way, and can solve the traditional pipeline well. Problems encountered in maintenance and construction.

The underground pipeline positioning and inspection system, as a new technology for underground facility positioning and information recording and query, can effectively improve the maintenance level of the pipeline network and increase the gold content of the underground pipeline network assets. In particular, it is very helpful for improving the speed of repairs, popularizing and applying PE pipelines, and reducing maintenance costs. It avoids the impact of large-scale excavation of road surfaces in search of pipelines on the lives of residents, and ensures the accurate identification and safety management of urban underground pipelines. In addition, a resource library for maintenance personnel to maintain and repair underground pipeline records can be established.

The underground pipeline positioning and inspection system includes RFID tags, readers and antennas to read pipeline diameter, pressure, tees, elbows, etc., so that the entire pipeline can be traced, and the use of navigation inspection pipelines Function. Obtain various relevant information about underground pipelines, including space location, size specifications, materials, transmission materials, transmission status, corrosion status, leakage point location, size and other pipeline health information.

Automatic data collection: RFID tags are embedded in the pipeline, and the attribute information of some pipeline equipment and facilities is stored in the tag to facilitate information management. The tags are waterproof, antimagnetic, high temperature resistant, less affected by the environment, suitable for harsh environments; passive and contact-free operation, RFID readers are penetrating and easy to use; fast reading speed, and can handle multiple electronic tags at the same time , Efficient and accurate, the operation process is transparent in real time.

Accurate positioning and fast search: accurately locate underground facilities, and can quickly find and intelligently read information on underground facilities, reduce excavation accident rates and reduce costs, improve emergency construction efficiency, and effectively protect underground facilities.
