Embodiment Construction

[0026] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0027] Such as figure 1 As shown, the angle sensor oriented to the Internet of Things of the present invention is covered with a V-shaped scattering unit on a layer of medium, and placed on the xy plane. The dielectric is Rogers 4350 with a dielectric constant of 3.48 and a thickness of 0.8mm. The V-shaped scattering unit consists of two metal arms A and B, both of which are 28.7×1mm in size 2 . The angle θ between A and B is used to encode address information. Angle θ between arm A and the positive direction of x-axis 1 Represents real-time angle information. The angle sensor is excited by a circularly polarized plane wave propagating along the -z direction, and the antenna of the receiving system is a dual-polarized antenna with polarization directions in the x and y directions;

[0028] figure 2 shows the address information of the angle sensor as 011 a...

Abstract

The invention relates to angle sensors, in particular to an angle sensor for the Internet of Things. According to the angle sensor for the Internet of Things, the radio frequency technology is used for recognition. The angle sensor for the Internet of Things comprises a dielectric slab and a V-shaped scattering unit, wherein the V-shaped scattering unit comprises a metal arm A and a metal arm B, the included angle between the metal arm A and the metal arm B is theta and is used for coding the address information of an object to be measured. The angle sensor is made to adhere to the object to be measured when used, and when the object to be measured rotates in the plane where the angle sensor is located, the address information and the real-time angle information of the object to be measured can be detected at the same time by measuring the reverse plural scattering field, in the horizontal polarization direction, of the angle sensor and the reverse plural scattering field, in the vertical polarization direction, of the angle sensor. The angle sensor for the Internet of Things is simple in structure and low in manufacturing cost, the frequency band occupied when the sensor works is narrow, and the spectrum efficiency is improved.

Description

technical field [0001] The invention relates to the field of angle sensors, in particular to an angle sensor oriented to the Internet of Things, which is characterized in that wireless radio frequency technology is used to realize the perception and detection of sensor information. Background technique [0002] At present, sensors for detecting angles are used in locomotives, electromechanical equipment, automobiles, ships, and even airplanes. One type of angle sensor uses a rotating shaft to count, and then measures physical quantities such as displacement and speed; there is also a Magnetic non-contact angle sensors, also known as non-contact potentiometers, are used in industrial automation equipment, construction machinery, textile machinery and other fields; there is also a type of inclination sensor that is often used for system level measurement, which can be divided into There are three types of "solid pendulum", "liquid pendulum" and "gas pendulum", all of which are...
