Embodiment 1

[0038] Such as figure 1 As shown, the multi-exploration geophysical field signal intelligent acquisition device includes: a working mode switching circuit, a signal conditioning circuit, an analog-to-digital converter, a processor, a communication module, and a working power supply; the processor controls the working mode switching circuit to The signal is transmitted to the input terminal of the designated signal conditioning circuit, wherein the operating mode switching circuit switches among multiple operating modes according to the received operating mode and acquisition parameters, and the operating modes include electrical acquisition, seismic, transient Any signal from variable electromagnetic, radio wave perspective and magnetotelluric, the signal is switched to the input end of the analog-to-digital converter through the working mode switching circuit, and the signal conditioning circuit processes the received signal and transmits it to the analog-digital converter. The...

Embodiment 2

[0047] The second embodiment: the difference between the second embodiment and the first embodiment is that a buffer and a memory are added on the basis of the first embodiment.

[0048] Such as Image 6 As shown, both the buffer and the memory are connected to the processor. The DSP processor allocates corresponding cache and storage space, the cache temporarily stores the data converted by the analog-to-digital converter in the processor, and the memory stores the data processed in the processor for a long time.

[0049] Such as Figure 7 As shown, the buffer and memory are all connected to the processor, the buffer is selected as IS61WV102416BLL chip, and the memory is selected as N25Q256A13EF840F chip.

Embodiment 3

[0050] The third embodiment: The difference between the third embodiment and the first embodiment is that the structure of the circuit in the smart collection device is different.

[0051] Such as Figure 8 As shown, a multi-exploration geophysical field signal intelligent acquisition device includes; a working mode switching circuit is connected with a multi-channel signal conditioning circuit, a multi-channel signal conditioning circuit is connected with a working mode switching circuit, and a working mode switching circuit is connected with an analog-to-digital converter circuit , The analog-to-digital converter circuit, WIFI, and atomic clock are connected to the processor, and the processor is connected to the memory and buffer. The signal conditioning circuit includes a buffer, a filter, a notch filter, a program-controlled amplifier circuit, and a limiter. Different signal adjustments can be realized through the connection of different devices. The notch is connected to th...

Abstract

The invention discloses an intelligent acquisition device and method for multi-exploration geophysical field signals, and relates to the technical field of geophysical exploration. The method comprises the following steps that: a processor controls a working mode switching circuit to send signals to the input end of a designated signal conditioning circuit; the working mode switching circuit switches the signals to the input end of an analog-digital converter; the signal conditioning circuit processes the received signals and transmits to the analog-digital converter; the analog-digital converter processes the signals and sends to the processor; and the processor is connected to a communication module. The intelligent acquisition device can take both active sources and passive sources intoconsideration. The method has the advantages that the intelligent acquisition device can acquire the same or different physical field signals in parallel, so that the detection method is diversified,and the exploration construction efficiency can be improved.

Description

Technical field [0001] The invention relates to the technical field of geophysical prospecting, and more specifically to a device and method for intelligent acquisition of multi-exploration geophysical field signals. Background technique [0002] Geophysical exploration is widely used in the exploration of resources such as oil and gas, minerals, hydrogeology, engineering geology, etc. It also plays an important role in the monitoring and early warning of various geological disasters. At present, the geophysical prospecting instrument market is mainly classified according to the exploration method: such as the V8 multi-function electrical high-density electrical method developed by Phoenix Geophysical Company of Canada, and the GDP-32 multi-functional electrical method workstation of Zonge Company of the United States Transient electromagnetism instrument, PROTEM transient electromagnetism instrument of Canadian Geonics company, German DMT company SUMMIT seismic system, etc., the...
