摘要

Seismic exploration is widely used in mining projects. A cable-free self-positioning seismograph has been developed by College of Instrumentation & Electrical Engineering of Jilin University that may collect and store seismic data wirelessly or by Ethernet. When large data sets are produced, data download may affect the schedule of a project. To improve the rate of transfer, a system that allows parallel download of multichannel seismic data is reported here. The system is based on private cloud technology and proportional integral derivative control. A private cloud was employed to provide suitable performance and availability. A proportional integral derivative control algorithm was developed for scheduling to maintain the load balance of the system. The system was employed in a seismic exploration project in Liaoning, China. The average download time of six lines was approximately 1.1 hours, demonstrating that the system reduced download time and enhanced exploration efficiency.
