Gas pipeline positioning underground electronic tag disc-shaped electronic marker marker

It is widely used in the positioning and identification of pipe networks, pipelines, and pipe corridors in gas, electricity, water conservancy, communications and other industries. It can be used to bury electronic markers at turning points, tee openings, etc. to mark and bury electronic signs during the pipeline laying process. The information that the device can carry includes: burial point characteristics, pipe material category and grade, pipe diameter, design pressure, pipeline burial depth, burial time and other information.

Working principle of underground electronic tags

The underground gas pipeline electronic identification system activates the underground electronic tag by sending an electromagnetic wave signal of a specific frequency through the detector. The signal is reflected back to the detector. Based on the signal strength, the detector can detect the precise location (latitude and longitude) and depth of the electronic tag.

√Packaging material: high density polyethylene shell

√Waterproof, anti-corrosion and durable

  Underground electronic markers | Electronic markers do not have an ID number. The buried longitude and latitude coordinate information is determined by the detector, and a unique ID number is assigned in the GIS geographical information management system, bound to the longitude and latitude coordinate information, and attached to the relevant Description. It is composed of a sealed and waterproof high-density polyethylene shell and a passive antenna inside. It has a built-in resonant circuit with a specific frequency. The effective service life is not less than 50 years, and the maximum detectable depth is 1.8 meters.

Underground electronic tags need to be used in conjunction with underground pipeline detectors to form an underground gas pipeline electronic identification system. The detector sends an electromagnetic wave signal of a specific frequency to activate the underground electronic tag. The signal is reflected back to the detector. According to the signal strength, the detector can detect The precise location (latitude and longitude) and depth of the electronic tag.

Functions:

1. The detector sends signals of a certain frequency intermittently

2. Underground electronic tags with the same resonant frequency absorb and Store signal energy.

3. After the detector sends a signal for a short period of time, it stops sending and enters the signal receiving mode.

4. When the detector stops sending signals, the underground electronic tag will release the stored energy and reflect it back to the detector, so the underground electronic tag does not require a battery to work.

5. The detector detects the returned signal strength to determine the specific location of the underground electronic tag.

6. The signal is strongest when the detector is closest to the underground electronic tag, that is, directly above the underground electronic tag.

Features:

(1) It is waterproof, antimagnetic, high temperature resistant and not affected by the environment.

(2) It adopts passive and contact-free operation and is easy to use. It only needs to be placed in the electromagnetic field formed by the detector to accurately read data, reducing or even eliminating the efficiency reduction and error correction costs caused by manual intervention in data collection.

(3) Reading data is fast and over a long distance. It can read the data stored inside the tag and associate it with the information in the background management system through the mobile Internet to display the tag information in real time.

(4) Reading does not rely on visible light, so visual visibility is not required and can be used in harsh environments where barcode and nameplate technology cannot adapt.

(5) It has a confidentiality function for information data, so that the data can only be read by a dedicated reader.

Installation plan

1. Before placing electronic signs, first evaluate whether connection binding is necessary. If necessary, use a tie to pass through the electronic marking hole and ensure a reliable connection, and then manually backfill both sides of the pipe with fine sand to the bottom of the electronic marker to ensure that the marking will no longer be deflected.

2. If the object to be marked is metal, it is recommended that the marker be spaced at least 10 cm away from it and filled with soil in between.

3. Backfill 15 cm above the logo to fix the position of the logo.

4. Backfill until it is level with the ground surface.
