Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a central recording system is used to control seismic data acquisition, then centralized control and coordination is improved, but system complexity and single point of failure risk increases
Solution Approach 1:
The patent divides the centralized control system into distributed autonomous source units, each capable of independent operation. Each source unit has its own controller that can autonomously execute survey procedures, eliminating the single central recording system while maintaining coordinated control through GPS synchronization and inter-unit communication.
Solution Approach 2:
Each seismic source unit is equipped with autonomous capabilities to independently control its own operation, process its own data, and communicate with other units. This self-service approach allows sources to operate independently without relying on a central system, reducing complexity while maintaining operational control.
2Reliability
If seismic sources operate independently without central control, then system reliability and operational independence is improved, but synchronization and coordination difficulty increases
Solution Approach 1:
The patent implements feedback mechanisms where each autonomous source unit continuously monitors its own status, GPS position, and timing, and adjusts its operation accordingly. Sources exchange status information and coordinate through standardized communication protocols, enabling synchronized independent operation without central control.
Solution Approach 2:
Survey procedures, timing schedules, and coordination protocols are pre-programmed into each autonomous source unit before deployment. This preliminary configuration allows sources to operate independently while maintaining synchronization according to pre-established survey plans, reducing the complexity of real-time coordination.
3Productivity
If traditional communication protocols are used for seismic data acquisition, then system simplicity is maintained, but real-time data management and quality control efficiency decreases
Solution Approach 1:
The patent employs standardized digital communication protocols with defined message formats, data structures, and transmission parameters optimized for real-time seismic data exchange. This structured approach enables efficient data management and quality control while maintaining manageable system complexity through parameter standardization.

AI summary
A method of controlling seismic data acquisition may include sending a first message to place a plurality of energy sources into an operating mode; sending a second message to place at least one of plurality of energy sources into a non-operating mode; and sending a third message from at least one energy source to a controller.
