Distributed transient electromagnetic data acquisition system based on wireless sensor network

Abstract

The invention relates to a distributed transient electromagnetic data acquisition system based on a wireless sensor network. The distributed transient electromagnetic data acquisition system is composed of an industrial personal computer, a coordinator, a plurality of router nodes, a plurality of terminal acquisition nodes and the wireless sensor network serving as a basic network, wherein the router nodes and the terminal acquisition nodes are distributed flexibly. The industrial personal computer is connected with the coordinator through a USB, and the terminal acquisition nodes, the router nodes and all nodes of the coordinator are in wireless connection with one another; the terminal acquisition nodes are used for completing acquisition and uploading of transient electromagnetic data; the router nodes are used for completing the router addressing and data forwarding function; the coordinator is used for completing storage, display and USB communication of the acquired data; the industrial personal computer is used for controlling the acquisition process of each node, displaying the data, and completing calculation of obtained data exploration parameters. The distributed transient electromagnetic data acquisition system has high exploration accuracy, connection wires between the nodes are omitted, field operation is convenient, work efficiency is improved, modular design is adopted for the nodes, and maintenance and replacement are convenient.

Description

technical field [0001] The invention relates to the field of geophysical detection science and technology, in particular to a distributed transient electromagnetic data acquisition system based on a wireless sensor network. Background technique [0002] Transient electromagnetic detection technology is a commonly used geophysical detection technology, which is widely used in resource exploration, geological structure detection, environmental investigation and monitoring, reservoir basement and dam crack exploration, etc. It has played an invaluable role in the field of geophysical detection instrument technology alternative role. [0003] The traditional transient electromagnetic detection adopts the working mode of single-channel transmission and single-channel reception. In order to enhance the signal-to-noise ratio and improve the acquisition accuracy, the time-domain superposition method is usually used, that is, the collected electromagnetic signals are periodically sup...
