Problems solved by technology

However, both electronic sensors and optical fiber sensors need to be connected with wires or optical fibers to obtain energy or transmit signals. When there are many measuring points, wiring is difficult. In addition, in the event of a disaster, the lines are easily damaged, resulting in sensor failure.

Abstract

The invention relates to a passive wireless tilt monitoring device based on a patch antenna, which includes a tag and a reader. The tag includes a fixed component and a movable component. The fixed component includes a second patch, a second dielectric plate, a microstrip feeder, a chip, and a ground plane. The second patch, the microstrip feeder, and the chip are connected in sequence and are arranged on one side of the second dielectric plate Above, the ground plane is set on the surface of the other side of the second dielectric plate, the shape of the first patch and the second patch is a fan ring, the second patch and the second dielectric plate are arranged face to face and concentrically, and the first dielectric plate surrounds the second dielectric plate The center of the two stickers is rotated and set on the second medium plate, and the label is set vertically on the measured object. Compared with the prior art, the invention realizes wireless passive detection, has simple structure, easy installation, little external interference, long service life, low cost and accurate positioning.

Description

technical field [0001] The invention relates to the field of structural health monitoring, in particular to a passive wireless tilt monitoring device based on a patch antenna. Background technique [0002] In the field of structural health monitoring, inclination is an important parameter for building health monitoring. The current common tilt sensors can be divided into mechanical, electronic and optical fiber. [0003] Mechanical tilt sensors have the advantages of easy design, low cost, reliable performance, and intuitive measurement data. However, the use of mechanical tilt sensors is limited, the measurement range is small, and it is difficult to connect to the network, so it is difficult to realize real-time monitoring. Electronic sensors and fiber optic sensors have the advantages of high integration, high precision and easy connection to the network, and can realize remote and real-time monitoring of building tilt. However, both electronic sensors and optical fiber...
