Embodiment Construction

[0012] Firstly, the solar power supply device is started to continuously provide power for the equipment. The control center uses the satellite GPS positioning and timing system to accurately locate all the transceiver subsystems of each monitoring point in the country and connect them to the GPS satellite clock source. The satellite link is used to signal the whole system to start working. When the whole system starts to work, the displacement sensor of each monitoring point monitors the horizontal and vertical three-dimensional space of the monitoring point. When there is a vibration, the sensor at the monitoring point will generate a displacement and alarm at the same time, and the information will be transmitted back to the control center through the satellite transmission system installed at the monitoring point.

[0013] Seismic waves spread outward in an arc, and those close to the center of the arc first generate displacement and alarms. The control center notifies oth...

Abstract

The invention discloses a satellite communication-based earthquake real-time monitoring system, which comprises a control center sub-system, a monitoring center sub-system, a displacement sensing sub-system, a solar power supply sub-system, a satellite global positioning system (GPS) high-precision positioning sub-system, a satellite GPS precision time service sub-system and a very small aperture terminal (VSAT) satellite communication sub-system. The three-dimensional measurement of earthquake waves in horizontal and vertical directions is realized by displacement sensor technology; equipment at all monitoring points is supplied with solar power; the three-dimensional navigation and positioning of the monitoring points are realized by using the GPS high-precision positioning technology with high anti-interference; the GPS precision time service system is used, so that the control center and all the monitoring points have the synchronous clock signals with the same frequency and the same phase; and the seamless coverage and networking of the monitoring system across China are realized by using the VSAT satellite communication technology.
