Description

Technical Field

[0001] The utility model belongs to the technical field of node equipment management in oil and gas exploration and development, in particular to a node channel door. Background Art

[0002] In recent years, with the improvement of acquisition technology and construction efficiency, the number of acquisition equipment required has increased day by day, and acquisition equipment management has become a pain point in the actual construction process. Traditional acquisition equipment management generally relies on a non-automated, paper-based system to record and track node equipment in and out of the warehouse, and the management of node instruments is completely done manually. This traditional management method has problems of low efficiency and low accuracy, and it is difficult to meet the requirements of fast and accurate node instrument management, which seriously affects the operating efficiency of node equipment and becomes a major obstacle to the development of acquisition construction management.

[0003] Using QR code labels to manage node devices is an implementation solution for node device management in recent years. A QR code label representing the node device is affixed to each node device. Management personnel use scanning devices to scan the QR code to manage the entry and exit, inventory, and maintenance of node devices.

[0004] Using QR code tags to manage node devices is a solution for node device management in recent years. However, using QR code management has the following disadvantages:

[0005] (1) The recognition distance is short.

[0006] (2) It is impossible to identify multiple tags simultaneously.

[0007] (3) The QR code label is easily damaged or lost during use.

[0008] Therefore, a node device management solution is needed that can identify multiple tags, has a long identification distance, and has tags that are not easily damaged. Utility Model Content

[0018] Preferably, the square small patch unit is connected to the reference ground in the middle through a metallized via to form an electromagnetic bandgap structure.

[0019] Preferably, the feeding network includes a T-type cross junction and a two-stage microstrip power division phase shifting network. The T-type cross junction divides the radio frequency signal into two signals with a power ratio of 2:3. The first-stage microstrip power division phase shifting network divides one of the output signals of the T-type cross junction into two equal-phase and equal-amplitude radio frequency signals, and adds the other output signal of the T-type cross junction to form three signals with a power ratio of 3:4:3.
