Embodiment Construction

[0025] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0026] refer to figure 1 As shown, one embodiment of the present invention is an earthquake monitoring and alarm system for rail transit, the system is mainly composed of an earthquake monitoring station, a linkage control center and a monitoring center, wherein:

[0027] The earthquake monitoring site includes at least two monitoring spaces. At least two strong motion instruments are installed in the monitoring space. The aforementioned strong motion instruments are connected to linkage logic processing equipment for real-time collection and recording of the location of the monitoring space by the strong motion instruments. Earthquake P wave or S wave, and judge whether the intensity value of the current P wave or S wave reaches the earthquake warning threshold. If the judgment result is yes, an alarm signal is generated and transmitted to the linkage logic together ...

Abstract

The invention discloses a seismic monitoring and alarming system used for the rail transit and belongs to the seismic protection and control systems. The system comprises a seismic monitoring site, a linkage control center and a monitoring center. At least one monitoring space is arranged in the seismic monitoring site. At least two strong-motion seismographs are installed in each monitoring space. The strong-motion seismographs are connected with linkage logic processing devices. A monitoring space is arranged in the linkage control center. The linkage logic processing devices are installed in the monitoring space. According to the invention, through the structures of the seismic monitoring site, the linkage control center and the monitoring center in the system, redundancy judgment can be performed on P-waves or S-waves in a seismic source; safety of seismic alarming judgment is ensured; seismic warning information can be given out as early as possible when the seismic occurs; a train which runs at the high speed is allowed to timely reduce speed and stop before the seismic occurs; the possibility of train derailment and overturning is reduced; life safety of passengers is ensured; accurate and timely after-seismic information is provided for superior command systems; and favorable conditions are created for disaster relief work.

Description

technical field [0001] The invention relates to an earthquake prevention and control system, more specifically, the invention mainly relates to an earthquake monitoring and alarm system for rail transit. Background technique [0002] The Wenchuan Earthquake that occurred on May 12, 2008 caused huge loss of life and property to our country. Among them, a freight car on the Po-Chengdu Railway derailed and caught fire in the tunnel due to the earthquake, causing the Baocheng Railway to be interrupted for several days, directly affecting the implementation of disaster relief work. This makes us realize the urgency of railway earthquake monitoring and alarm technology research. In a large number of earthquake phenomena, only a few extremely large earthquakes cause significant damage to the structure of the railway, and most of them are earthquakes with slightly lower intensity. The EMU will have a major impact, and may even cause the subversion of the EMU. According to the pre...
