Embodiment Construction

[0048] Such as figure 1 As shown, the present invention includes a communication module 1 , a main control module 2 , a DSP (Digital Signal Processing, digital signal processing) module 3 , a transmitting module 4 , a receiving module 5 and a power supply module 6 . Triggered by the synchronous command of the upper computer 7, the main control module 2 triggers the DSP module 3 to generate the required signal sequence, and the energy is sent to the water by the transducer 8 through the transmitting module 4. Transducer 8 receives signals transmitted by other nodes, and sends them to DSP module 3 after being preprocessed by receiving module 5 . The DSP module 3 extracts the target signal and calculates the delay value, and sends it to the main control module 2 . The main control module 2 packs the 4 delay measurement data into a communication protocol and sends them by the communication module 1 .

[0049] The asynchronous serial interface (SCI) is used between the communicat...

Abstract

The invention provides a measurement and control system of an in-ocean towed multi-linear array acoustic positioning device, comprising a communication module for data interaction between a master control module and an upper computer; the master control module for performing data interaction with the communication module and a DSP module and controlling the actions of the DSP module, a transmitting module and a receiving module; the DSP module for generating a signal sequence and transmitting it to the transmitting module, and transmitting the data transmitted by the receiving module to the master control module after extracting a target signal and calculating a time delay value; the transmitting module for transmitting the signal sequence transmitted by the DSP module to an energy converter; the receiving module for preprocessing the signal transmitted by the energy converter and then transmitting the preprocessed signal to the DSP module; a power supply module for supplying power tothe communication module, the master control module, the DSP module, the transmitting module and the receiving module, respectively. By adopting the master control module, the invention realizes intelligent control; by utilizing the communication module, the communication precision is increased; and by using the receiving module and the transmitting module, signals are collected and transmitted more stably and reliably.

Description

technical field [0001] The invention relates to a measurement and control system for an ocean towed multi-line array acoustic positioning device. Background technique [0002] With the gradual development of offshore oil exploration technology to high-precision and high-resolution levels, the exploration system requires geophones to have more accurate positioning capabilities. Seismic geophones arranged at a certain interval collect seismic wave data. The reduction of the array spacing and the increase of the sampling rate can obtain higher-precision and higher-resolution stratigraphic imaging maps, which are important for geological data interpretation and oil and gas exploration. significance. However, if the location of the geophone cannot be precisely positioned, the obtained stratigraphic data cannot be continuously imaged, and the obtained data may even be unreliable. Therefore, in order to collect and analyze geological section data with high resolution and high pre...
