China's own earthquake alarm system has been developed through the identification.

28 <P> author Hebei Science and Technology Department from the scientific and technological achievements appraisal meeting that, by our own R & D breakthroughs in earthquake monitoring and alarm technology there, including seismic sensing alarm system, 10 seconds ahead of the region can be perceived Earthquake Information ., set the magnitude according to an alarm signal before the escape and save themselves for the shock win precious time. .At present, earthquake seismic sensing alarm system and elevator monitoring system has been through the identification. .</ P> <P> Qinhuangdao, according to system development prospects of Optoelectronic Technology Co., Ltd. company introduced seismic sensing alarm system perceived by the seismic station, earthquake emergency life-saving devices and statistical analysis of urban earthquake information center to collect the three parts. .Seismic sensing stations in real-time detection of ground motion acceleration anomaly, when the focal issue of the longitudinal and transverse wave radiation to the Earth's surface, seismic sensing alarm apparatus according to their strength, intelligence judgments about the formation of surface waves in the region of seismic magnitude, .Depending on crustal thickness and focal areas of different shades, can be 10 seconds to 30 seconds ahead of sensing seismic information, and automatic alarm to remind the escape. .According to the needs of the coverage, earthquake awareness workstation distinguishing the family, community, city and other range equipment. .</ P> <P> earthquake emergency rescue device with emergency hand from power, DC power output, indoor emergency glass break, flashing police for rescue, high-frequency voice alarm, LED flashlight lighting, seat belts quickly cut off, AM / .FM FM radio, mobile phone charging and other functions, self-help and waiting to meet the various needs of the rescue process. .</ P> <P> urban earthquake information center of the collection of statistical analysis is the perception of earthquake early warning system for the city to prepare for earthquake information database application, it can be more variety in the process of recording earthquake data for seismic research workers for future use .. .Science and Technology Department of Hebei Province science and technology information and intelligence of the novelty search finds that the system has not been reported in the literature at home and abroad. .</ P> <P> In addition, the research and development of earthquake monitoring and warning technology also includes the elevator seismic monitoring system, the Hebei Science and Technology Department of the novelty search finds information and intelligence technology, the system is also an initiative at home and abroad. .The system in the earthquake occurs, the output corresponding electrical signals, amplified through the filter, the ADC gave the microprocessor be processed, so that the elevator when the earthquake occurred before the effective access control or running in .leveling the floor recently opened, releasing the passenger elevator, passenger elevator possible to save lives and reduce damage to elevator equipment. .</ P> <P> crustal stress by the China Seismological Bureau, Research Professor Zu Xi Ouyang said the new set of seismic monitoring and alarm technology, earthquake alarm, staff self-help, regional, better integrate disaster prevention and mitigation, technology .reached the advanced level of similar products at home and abroad. .Its applications, can greatly reduce the fear of the people of the earthquake and the earthquake came to remind and help self-help and help. .</ P>.
