چکیده
This paper mainly introduces a set of high-speed railway earthquake early warning test system based on LabVIEW, which serves for the indoor prototype early-warning system, is used to simulate wave generation instead seismic sensors. From perspective simulation, (EEW) virtual instrument (VI) technology developed. Through and non-seismic interference are simulated, generated sent, so as carry out research current EEW in China. Based development platform The function verified by an example, consistency between original waveform acquisition analyzed. results show that amplitude accuracy 0.005 ± 0.002 gal acceleration peak time no difference, is, VI accurate reliable.

Earthquake Early Warning System Based on Multiple Sensor Network
Earthquake is one of the major natural calamity. So prediction of the reach of earthquake event to the various locations could result in minimizing the disaster due to it. This system contains the design of sensor system and the techniques used for detection and processing of the received signals in real time. In this system, an earthquake which is also known as a tremor or temblor is the resul...
متن کاملSpeed-Breaker Early Warning System
There is evidence to support the claim that speedbreakers can cause accidents and injury. When a vehicle approaches a speed-breaker at a speed greater than some threshold velocity, the risk of accident or injury is substantial. Speed-breakers are inconspicuous in low visibility conditions, like at night, or when there is fog, rain or snow. This problem is particularly acute in developing countr...
متن کاملAutomatic earthquake confirmation for early warning system
Earthquake early warning studies are shifting real-time seismology in earthquake science. They provide methods to rapidly assess earthquakes to predict damaging ground shaking. Preventing false alarms from these systems is key. Here we developed a simple, robust algorithm, Authorizing GRound shaking for Earthquake Early warning Systems (AGREEs), to reduce falsely issued alarms. This is a networ...
متن کاملCrowdsourced earthquake early warning
Earthquake early warning (EEW) can reduce harm to people and infrastructure from earthquakes and tsunamis, but it has not been implemented in most high earthquake-risk regions because of prohibitive cost. Common consumer devices such as smartphones contain low-cost versions of the sensors used in EEW. Although less accurate than scientific-grade instruments, these sensors are globally ubiquitou...
متن کاملCISN ShakeAlert – An Earthquake Early Warning Demonstration System for California
To demonstrate the feasibility of earthquake early warning (EEW) in California, we have developed and implemented the CISN ShakeAlert demonstration system. A Decision Module combines estimates and uncertainties determined by three algorithms implemented in parallel, τc-Pd Onsite, Virtual Seismologist, and ElarmS, to calculate and report at a given time the most probable earthquake magnitude and...
