Title:
EXPLORATION MACHINE SYSTEM AND MANAGEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2017/056283
Kind Code:
A1
Abstract:
The present invention has: an epicenter management unit for transmitting signals to, and receiving signals from, a source controller for controlling an artificial epicenter; a plurality of sensor terminals for managing sensors for receiving reflected waves in accordance with a sampling timing period and generating vibration data; and a management device for managing the epicenter management unit and each of the sensor terminals. During a measurement phase, the epicenter management unit acquires, as first timing characteristics information, information that includes: the output timing of vibration trigger signals being outputted to the source controller among signals to be received and transmitted; and the reception timing of a vibration-start-timing signal subsequently outputted from the source controller. The management device assesses vibration characteristics of the artificial epicenter on the basis of the first timing characteristics information, calculates second timing characteristics information in accordance with the assessment results, configures the epicenter management unit with the second timing characteristics information, calculates the timing adjustment amount used in order to adjust the sampling timing for each of sensor terminals relative to the sensors, and configures each of the sensor terminals with the timing adjustment amount. During an operation phase, the epicenter management unit calculates the timing adjustment amount used in order to adjust the output timing of the vibration trigger signal on the basis of the second timing characteristics information configured from the management device.
