Direct-current combined field intensity and ion current density synchronization measurement system based on wireless communication

Abstract

The invention relates to a direct-current combined field intensity and ion current density synchronization measurement system based on wireless communication. The system comprises at least 10 direct-current combined field intensity probes, 10 ion current density probes, one upper computer and one PC terminal. A built-in lithium battery is used to provide power for the direct-current combined field intensity probes, the ion current density probes and the upper computer so that long-time field measurement can be achieved. Each direct-current combined field intensity probe and each ion current density probe are communicated with the upper computer through using a wireless communication module. The upper computer and the PC terminal are connected through a USB connecting line. Measurement arrangement and a measuring point position can be conveniently adjusted so that operating efficiency is greatly increased and labor intensity is reduced. The system supports multiple devices, synchronously measures direct-current combined field intensity and ion current density in a high precision mode and really reflects a level and distribution of the direct-current combined field intensity and the ion current density so that an important basis is provided for extra / ultra-high-voltage direct current transmission project electromagnetic environment monitoring, evaluation and influence research.

Description

technical field [0001] The invention relates to a synchronous measurement system, in particular to a synchronous measurement system of direct current synthetic field strength and ion current density for wireless communication. Background technique [0002] The DC combined field strength and ion current density are the main parameters for DC electromagnetic environment assessment. Unlike the AC electric field and magnetic field, which are symmetrical on both sides and are less affected by the external environment, the DC combined field strength and ion current density are affected by wind speed, wind direction, climate and other indicators. The change is obvious, and the ion current density on both sides of the pole wire is significantly different. Therefore, it is necessary to measure multiple points on both sides of the line at the same time, and perform statistical analysis on the measurement data. At present, multiple probes (generally no less than 10 of the two types) ar...
