Subsea Measurement Data Compression via Dual Execution Environments

The patent applies preliminary action by performing data processing and compression operations on the subsea device before data transmission. The raw measurement data is processed locally to extract only essential information, reducing the data volume that needs to be transmitted acoustically. This pre-processing step eliminates the need to transmit large volumes of raw data, thereby significantly reducing communication time and power consumption while maintaining the use of acoustic communication for its advantage of long range.

The patent applies segmentation by separating the device firmware from user applications. The subsea device contains core firmware that handles basic operations and data acquisition, while user-defined applications are executed separately. This allows multiple applications to run on the same hardware platform without increasing the core device complexity. Users can load different applications as needed, providing versatility without requiring complex firmware for each specific application scenario.

The patent reduces power consumption by performing preliminary data processing and compression on the subsea device before transmission. By extracting only essential information from raw measurements and compressing the data locally, the volume of data requiring acoustic transmission is dramatically reduced. Since acoustic communication is power-intensive, transmitting smaller data sets significantly reduces the energy required for communication while maintaining the long-range capability of acoustic modems.

The patent applies the extraction principle by selectively extracting essential information from raw measurement data on the subsea device. Instead of transmitting all raw data, the system processes the data locally and extracts only the most relevant parameters and findings. This extraction approach maintains measurement precision by preserving critical information while eliminating redundant data, thereby significantly improving transmission efficiency and reducing the burden on acoustic communication channels.
