Description

Three-dimensional omnidirectional electromagnetic pulse measurement system, measurement networking and vehicle-mounted measurement platform

Technical Field

The utility model relates to an electromagnetic pulse measures the field, especially relates to a three-dimensional qxcomm technology electromagnetic pulse measurement system, measurement network deployment and on-vehicle survey measuring platform.

Background

With the rapid development of electronic informatization and industrial automation in modern society, even a small pulse may cause damage to the entire circuit board, causing serious damage and interference to the operation of power systems and electrical equipment. Therefore, in order to protect against electric field pulses, measurements of electromagnetic pulsed electric fields, in particular transient pulsed electromagnetic fields, are required. At present, an optical electromagnetic pulse sensor based on an electro-optical effect has become an ideal choice for electromagnetic pulse sensing due to the advantages of strong anti-interference performance, wide response bandwidth, wide range and the like, but the test result of the electromagnetic pulse sensor is greatly influenced by the arrangement angle of a test device due to the limitation of the directivity of an electro-optical crystal, and all electric field information in a space cannot be acquired simultaneously. The repeatability of the electromagnetic pulse signal is poor, so that the measurement cannot be carried out by adopting a method of testing and reconstructing the same electromagnetic pulse sensor for multiple times. In the field of strong electromagnetic pulses, measurement of three-dimensional electromagnetic pulse intensity has been the focus of attention.

A set of three-dimensional omnidirectional integrated optical waveguide electric field sensors was developed by flood et al [3Dintegrated medical E-field sensing for lighting in electromagnetic measurements (LEMP) measurement [ J ]. IEEEPhotonics technologies, 2014 ]. Three lithium niobate integrated optical waveguide electric field sensors which are manufactured and packaged are installed and fixed on three side surfaces of a regular triangular prism, so that included angles between three dipole antennas of the three integrated optical waveguide electric field sensors and three edges of the regular triangular prism are all just 54.7 degrees. The three-dimensional electric field measurement system can simultaneously measure three components of the electric field polarized along any direction in space, so that the size and direction of any electric field in space can be obtained. However, the sensor requires three tunable lasers, and is complex and costly. In addition, the maximum response frequency of the sensor is 500MHz, and the sensor is generally required to have a GHz measurement bandwidth.

At present, although the existing three-dimensional electromagnetic pulse measurement system design can realize three-dimensional measurement of an electric field, the measurement stability and sensitivity are low. In addition, the current three-dimensional electromagnetic pulse measurement system focuses on using a single three-dimensional electromagnetic pulse sensor to perform point measurement of electromagnetic pulses, and effective measurement of electromagnetic pulse distribution in a certain space cannot be achieved.
