Application of RFID technology in urban underground pipelines

Urban underground pipelines are the "lifeline" of the city and are responsible for transmitting information and energy. With the rapid development of digital cities, in order to ensure the healthy operation of the city's "lifeline", RFID technology is applied to urban underground pipelines to accurately locate, search, identify and manage underground facilities, and help establish the informatization of underground facilities. Data lays a solid foundation for information management of underground equipment.

Underground pipeline electronic marker

The RFID underground pipeline electronic marker has a built-in passive chip and adopts a one-time injection molding process. It has good waterproof performance and the ability to penetrate and bypass obstacles. It has a long service life and a long identification distance.

Electronic sign detector

The underground pipeline electronic marker detector can quickly and accurately find and locate the underground pipeline electronic marker. Through the rapid or gentle sound emitted when the detector recognizes the marked object, the location, depth, route, etc. of the marked object can be obtained. Attribute information, no need for excavation, troubleshooting and positioning.

Applications

During construction and installation, the relevant data of underground pipelines, pits and pipelines in the pits are entered into electronic markers, and the electronic markers are installed near the directly buried pipelines or on the walls of the pits as identity marks of underground facilities. The ID code of the electronic marker is collected through the electronic identification detector and used as a location point mark to collect the GPS data of the location point. The front-end software generates a label location point icon on the GIS electronic map by inputting the GPS data, editing, and binding the ID number. And related to the directly buried pipelines, wells and well pipelines and other information in the database one by one.

During inspection and maintenance, use the tag and its unique code as an index, use the electronic identification detector to scan and identify, quickly search and detect the location point of the electronic identification device, complete the positioning and data reading of the electronic tag at the location point, and obtain The location of directly buried pipelines and wells, the laying methods of pipelines, wells and pipelines in the wells, label numbers, longitude and latitude, burial depth, pipeline names, etc., to complete the positioning, informationization and visual management of underground pipelines.

Application benefits

1. Passive and contact-free operation, reducing or even eliminating the efficiency reduction and error correction costs caused by manual intervention in data collection;

2. RFID tags have large data storage capacity, which facilitates automatic transmission and information management of data information;

3. It has strong penetrability and strong anti-interference ability, and can be used in harsh environments without being affected;

4. RFID tags have high security performance and can keep cable data confidential.
