Method and system of magnetotelluric synchronous detection and real-time inversion

A method and system of magnetotelluric synchronous detection and real-time inversion, wherein the system comprises:

• a detection and inversion host (M) with wireless networking function;
• and
• N2-1 detection and inversion extensions (Si) with wireless communication functions;
• the distance between each two detection and inversion extensions (Si) is D, wherein i=1, 2, . . . , N2-1, and N is an odd number, wherein
• the detection and inversion host is configured for collecting magnetic field signal in the area and the electric field signal at measuring points, wireless networking and cooperation, and synchronous detection and real-time inversion control of the respective detection and inversion extensions (Si);
• the detection and the inversion extensions (Si), under cooperative control of the detection and inversion host, is configured to synchronously collect the electric field signal at the measuring points and invert the detection data at the measuring points in real-time;
• during detection, the detection and inversion host and the detection and inversion extensions (Si) are arranged across N2 measuring points in the detection area and the data at each measuring point is collected synchronously, and the detection efficiency is increased by N2 compared to single point detection, and the influence of the spatial and temporal variance in asynchronous detection on the inversion result is avoided;
• in the inversion, the detection and inversion extensions (Si) at each measuring points carryout real-time inversion of the collected data under cooperative control of the detection and inversion host and return the inversion result to the detection and inversion host, and it makes full use of the calculation ability of the detection and inversion host and the detection and inversion extensions (Si), and it minimizes the data transmission volume and saves the inversion calculation time.
