MULTI VIBRATOR WAVE MONITORING SYSTEM

摘要

PURPOSE:To improve measurement accuracy in a system consisting of a multitude of artificial earthquake source devices and a prospector by synchronizing the vibration phase of one of the artificial earthquake source as a master with another one as a slave using the communication from the prospector. CONSTITUTION:A system is constituted of a multitude of artificial earthquake source device and a prospector to observe vibration. The artificial earthquake device controls the onset of the vibrator based on the phase difference resolving information and the movement start command from the prospecting machine. The synchronization control means of the prospecting machine receives the information concerning the vibration of the vibrator on the artificial earthquake source device with a communication means and compares the phases between one artificial earthquake source device as a master and another one as a slave. Then it sends phase difference resolving information to resolve the phase difference between each artificial earthquake source device and movement start command. Each artificial earthquake source device controls the start timing of the vibrator based on this information.
