The invention discloses an underwater data acquisition and transmission circuit used for offshore engineering investigation to overcome the shortcoming that existing seismic acquisition equipment used for offshore high-resolution engineering survey is low in resolution ratio. The underwater data acquisition and transmission circuit comprises an acquisition and processing circuit and a transmission circuit, wherein the acquisition and processing circuit is set to receive a seismic reflection signal according to an acquisition instruction, covert the seismic reflection signal into a digital signal and conduct smoothing; the transmission circuit is set to transmit the seismic reflection signal after the smoothing to an overwater system, receive the acquisition instruction issued by the overwater system and forward the acquisition instruction to the acquisition and processing circuit. The underwater data acquisition and transmission circuit can finish the acquisition and transmission of the seismic reflection signal simultaneously and improve the resolution ratio of the seismic acquisition equipment, thereby realizing the design which is high in integration and low in power consumption.
Description
technical field [0001] The invention relates to a data acquisition and transmission circuit, in particular to an underwater data acquisition and transmission circuit for marine engineering survey. Background technique [0002] With the gradual development of offshore oil exploration technology to high-precision and high-resolution levels, a series of new requirements such as well site surveys, proving shallow geological structures, and evaluating the distribution of drilling platforms have put forward higher requirements for exploration equipment. [0003] Shallow high-resolution seismic instruments can provide high-resolution seismic data to obtain clearer imaging of subsurface geological structures. In addition, they can also be applied to the field of marine geological surveys to detect the seabed of coastal interior shelves, continental slopes and deep-sea basins. topographical features, etc. [0004] Seismic acquisition equipment used for offshore high-resolution engin...
