Embodiment Construction

[0010] 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.

[0011] 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 provides a system for real-time monitoring earthquakes. The system comprises a control center subsystem, a monitoring center subsystem, a satellite global position system (GPS) high precision positioning subsystem, a satellite GPS precision time service subsystem and a very small aperture terminal (VSAT) satellite communication subsystem; the capacities of three-dimensional navigating and positioning monitoring points are achieved by adopting a GPRS high precision positioning technology, thus the system has good anti-interference; by adopting the GPRS high precision positioning technology, the monitoring centre and each monitoring point have a synchronous clock signal of the same frequency and same phase; the seamless covering and networking of the monitoring system are achieved in national range by adopting the GPS precision time service system; and the VSAT satellite communication subsystem comprises a main station (control center), a satellite and 1-k numbered VSAT terminals (shift monitoring points).

Description

technical field [0001] The invention belongs to the technical fields of displacement measurement, geometric position measurement, GPS high-precision positioning technology, GPS precise timing system and VSAT satellite communication. Three-dimensional measurement of the horizontal and vertical directions of the safety of large buildings; the use of GPS high-precision positioning technology to achieve three-dimensional navigation and positioning capabilities for monitoring points, with good anti-interference; the use of GPS precise timing system to realize the control center and Each monitoring point has a synchronous clock signal with the same frequency and phase; VSAT satellite communication technology is used to realize seamless coverage and networking of the monitoring system nationwide. Background technique [0002] The scale of my country's economic construction is constantly expanding, and large-scale construction of high-rise buildings, bridges, dams and other large bu...
