AI Technical Summary
Existing downhole communication network scheduling methods cannot effectively cope with the dynamic changes in the complex downhole environment, resulting in untimely transmission of critical safety data and failing to meet the requirements for high reliability and low latency communication.
By acquiring the communication channel blockage status, tunnel humidity fluctuation data, and data packet priority in the underground environment, a blockage status distribution map is generated, the data packet order is dynamically reconfigured, the time slot allocation granularity is optimized, and an adaptive time slot configuration scheme is generated by combining multipath reflection interference assessment and antenna gain compensation.
It significantly improves the reliability and stability of downhole communication, optimizes network resource utilization, enables adaptive capabilities to dynamic environmental changes, and ensures deterministic and real-time transmission of critical business data.
