An rfid-based pipeline identification system

Abstract

An RFID-based pipeline identification system, including a steel-plastic composite winding pipe, an electronic marker, a remote detection and reading and writing device, an underground pipeline data processing system, and a grounding conductor attached to the outer pipe body of the winding pipe; the winding pipe and the electronic identification The device is buried underground, and the detection and reading device communicates with the electronic marker on the ground to read its information and communicates with the data processing system to send the read information to the processing system; the electronic marker includes a radio frequency chip and a wired or wireless connection with the chip Passive LC resonant circuit, the winding tube includes a metal strip that is spirally wound on the outside of its plastic tube wall, and the outside of the metal strip is covered with a plastic protective layer; the grounding conductor and the metal strip of the winding tube are insulated from each other and are electrically connected to the ground terminal of the resonant circuit. One electrode of the resonant circuit resonant capacitor is electrically connected. The invention overcomes the defect that the existing electronic marker can identify the shallow embedding depth, which makes it difficult to detect the path of the buried steel-plastic composite winding pipe, and has simple structure, reliable performance and easy implementation.

Description

technical field [0001] The invention relates to a system for identifying the pipeline path of an underground steel-plastic composite winding pipe. Background technique [0002] In the municipal pipe network, the daily maintenance and fault repair of the steel-plastic composite winding pipe buried underground is an essential work. For the positioning of underground steel-plastic composite winding pipes, the traditional method is to use the prominent markers set on the ground to compare with the relevant reference objects (pipeline points) on the drawings to find the pipeline path. The above-mentioned pipeline points include marks exposed on the ground or buried underground conductors, as well as various spherical (or dish-shaped) electronic markers. Since the municipal pipeline network is usually buried deep, when laying the municipal pipeline network, the electronic marker is usually used As a pipeline point, the marker is buried above the pipeline at a detectable position ...
