Embedded File Network Server for Seismic Data Stream Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Seismic acquisition equipment lacks a file network module to convert data streams into files for remote network communication, leading to restricted local storage and increased development and hardware costs, along with potential data transmission issues.
Innovation Solution
An embedded file network server with a broadband power management module, main control unit, serial-port-to-RS232 module, PHY bridge layer, SD card, and network interface, which automatically converts seismic data streams into files and transmits them to remote servers, using adaptive baud rate recognition and dual-channel DMA transmission for efficient data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seismic acquisition equipment integrates remote network transmission hardware, then data can be transmitted to remote servers, but device complexity increases and assembly becomes difficult
Solution Approach 1:
The patent divides the seismic acquisition system into separate functional modules: the acquisition equipment and the embedded file network server. The server is an independent unit that can be separately manufactured and then integrated, reducing the complexity of integrating remote transmission hardware directly into the acquisition equipment.
Solution Approach 2:
The embedded file network server acts as an intermediary device between the seismic acquisition equipment and the remote server. It receives data streams from the acquisition equipment via serial port or SPI interface, converts them to files, and transmits them to the remote server, thereby eliminating the need to integrate complex transmission hardware into the acquisition equipment itself.
2Adaptability or versatility
If seismic acquisition equipment includes integrated file network module, then data streams can be converted to files for remote communication, but manufacturing costs and development costs increase
Solution Approach 1:
The embedded file network server is designed as a universal device that can work with different types of seismic acquisition equipment through standard interfaces (serial port, SPI). It provides multiple functions including data stream reception, file conversion, and network transmission, making it a cost-effective multi-functional solution rather than requiring custom integrated modules for each acquisition device.
Solution Approach 2:
The embedded file network server is a self-contained unit with all necessary components (power management, control unit, storage, network interface) integrated into one device. It independently performs data conversion and transmission without requiring additional hardware or software modifications to the seismic acquisition equipment, thereby reducing overall manufacturing and development costs.
3Reliability
If seismic acquisition equipment uses separate remote transmission hardware, then network functionality is achieved, but hardware waste occurs when function is not needed
Solution Approach 1:
The embedded file network server provides dynamic configurability through software, allowing the remote transmission functionality to be enabled or disabled as needed. The hardware remains but can be deactivated or repurposed, eliminating the waste associated with permanently integrated hardware that cannot be easily removed or repurposed when the function is not required.
4Reliability
If custom remote transmission hardware is developed for seismic equipment, then specific protocol requirements are met, but protocol deviations cause transmission abnormalities
Solution Approach 1:
The embedded file network server uses standardized, proven communication protocols and interfaces (serial port, SPI, Ethernet) that have been thoroughly tested and documented. Rather than developing custom hardware that may have protocol deviations, the server acts as a reliable intermediary that correctly implements protocol conversion, ensuring accurate data transmission without the manufacturing precision issues of custom-hardware development.

AI summary
An embedded file network server based on a seismic data stream includes a broadband power management module, a main control unit, a serial-port-to-RS232 module, a PHY bridge layer, an SD card, and a network interface. The main control unit includes serial port, an SDIO interface, an internal RAM, DMA units, and a MAC drive layer. The main control unit performs seismic data interaction with an external device through the serial port, and receives seismic data through an internal interruption, and the received seismic data stream is stored in the internal RAM. The internal RAM transfers the received seismic data stream to the SDIO interface and MAC driver layer through the DMA units. The SDIO interface stores the seismic data stream in the SD card for data backup. The MAC driver layer is coupled to the PHY bridge layer for inputting and outputting the seismic data stream.
