Problems solved by technology

my country's high-speed railway equipment technology, train operation control system, catenary over-phase separation technology, track circuit system, etc. are different from those of Japan, France and other countries; at present, there is no ready-made earthquake early warning system that can meet the actual needs of my country's high-speed railway
[0005] In addition, the existing earthquake site monitoring equipment cannot provide early warning of earthquake P waves, and after an earthquake, the traction substation system and signal system cannot be triggered at the same time
When an earthquake occurs, the earthquake protection effect is greatly weakened because the earthquake information cannot be transmitted to the railway control system in a timely and effective manner.
At the same time, after the earthquake, the earthquake warning information cannot be transmitted to the central system of the high-speed railway earthquake early warning and monitoring road bureau, so that it is impossible to provide guarantee for the earthquake warning in a wider range of the high-speed railway earthquake early warning and monitoring road bureau central system

Abstract

The invention discloses a high-speed railway seismic early-warning on-site monitoring system. The system can real-time pick up seismic original wave forms, conducts seismic analysis and makes corresponding determination, forms a P-wave early-warning and threshold alarm, and transmits seismic information to a traction substation system and a train control system separately through a traction substation interface and a signal interface module, thus the method can provide effective protection to trains in operation, and greatly shortens protection time for earthquakes. In addition, the method can transmit seismic alarm information to a center system of a high-speed railway seismic early-warning monitoring railway administration bureau, and ensures that the center system of the high-speed railway seismic early-warning monitoring railway administration bureau to provide earthquake safety and protection in a larger area.

Description

technical field [0001] The invention relates to the technical field of railway earthquake early warning and protection, in particular to an on-site monitoring system for high-speed railway earthquake early warning. Background technique [0002] my country is a country with frequent earthquake disasters, and the threat of earthquake disasters to the safety of high-speed train operation cannot be ignored. Japan's high-speed railway operation experience shows that earthquake early warning is an effective means to prevent high-speed train earthquake disasters. [0003] The earthquake early warning system uses the great difference between the electric signal and the seismic wave propagation speed. After the earthquake, the electric signal is used to send an alarm signal to the area where the destructive earthquake wave has not yet reached, so that the high-speed train will slow down or stop as soon as possible to prevent or mitigate the earthquake. The hazards brought by disaste...
