Abstract

The invention provides a nonmetal position sensor, an antenna automatic positioning device and an antenna automatic positioning system for an electromagnetic compatibility test. The nonmetal position sensor comprises a cylinder body, a piston and a piston rod. The side wall of a lower cavity of the cylinder body is provided with a first radial pore, a second radial pore at the lower end of the first radial pore, and a third radial pore which is symmetrically arranged in the axial direction of the first radial pore; when the piston rod rises to the first position, the first radial pore and the third radial pore are communicated; the nonmetal position sensor sends a first pressure signal to the outside; when the piston rod drops to the second position, the first radial pore and the second radial pore are communicated; and the nonmetal position sensor sends a second pressure signal to the outside. The nonmetal position sensor for an electromagnetic compatibility test is totally made of nonmetal materials, thus maximumly avoiding the electromagnetic interference of test equipment to the test area.

Description

technical field [0001] The invention relates to supporting equipment for electromagnetic compatibility testing, in particular to a non-metallic position sensor, an antenna automatic positioning device and a system for electromagnetic compatibility testing. Background technique [0002] When performing electromagnetic interference (Electromagnetic Interference, EMI) testing, it is necessary to use the antenna bracket to carry the antenna to test the object to be tested. If the test distance from the object under test to the antenna is manually positioned by the operator every time, it is not only inefficient, but also prone to improper positioning and affects the accuracy of the test. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a non-metallic position sensor, an antenna automatic positioning device and a system for electromagnetic compatibility testing. [0004] In a first aspect, the present invention provides a n...
