Abstract

The invention discloses an intelligent autonomous networking earthquake early warning equipment and method. In the equipment, the earthquake monitoring front-end is composed of data acquisition, edge computing and cooperative communication modules, and has the capability of autonomous networking, and is used to realize intelligent strong earthquake identification , early warning calculation and robust communication; acquisition module, including GNSS module and MEMS accelerometer; calculation module, using embedded microprocessor, used for real-time calculation of earthquake trigger confirmation signal and seismic wave information according to multi-source monitoring data, if If the earthquake trigger confirmation signal is greater than the set threshold, then all the earthquake monitoring front-ends in the ad hoc network that have identified the vibration form a temporary monitoring network to form a networked mutual judgment of strong earthquakes and a networked earthquake early warning information solution; the communication module, The radio frequency chip that supports long-distance wireless transmission is used; it is used to form an intelligent wireless communication ad hoc network, and transmit and receive seismic waves and early warning information obtained by the computing module. The invention can be widely used in earthquake early warning systems, and has the advantages of low cost, low power consumption, autonomy, intelligence, high timeliness, high reliability and the like.

Description

technical field [0001] The invention relates to the technical field of earthquake early warning, in particular to an intelligent autonomous networked earthquake early warning equipment and method. Background technique [0002] Earthquake Early Warning System (EEWs) refers to relying on the seismic network near the potential epicenter to quickly estimate the location, scope of influence, and degree of earthquake damage in the shortest time after the earthquake, before the destructive S-wave and surface wave reach the early-warning area. A real-time earthquake information processing system that issues warnings. As one of the means to effectively mitigate earthquake disasters, the earthquake early warning system requires that it can provide reliable early warning information of earthquake parameters for the early warning area in the shortest time, so it has high requirements for effectiveness and reliability. [0003] However, to provide more reliable earthquake parameters, th...

Problems solved by technology

[0003] However, to provide more reliable earthquake parameters, the earthquake early warning system needs longer time seismic data and more station measurement data. However, with the sharp increase in data volume, it will put pressure on the communication network and data processing center. It will cause network congestion and failure and increase the overall data delay of the system, thereby affecting the effectiveness of the system

In addition, the transmission network that relies on fixed communication base stations or gateways, after a major earthquake damages the base stations or gateways, the data of the stations cannot be transmitted, causing the entire system to be paralyzed

However, the earthquake early warning system relies on a single data processing center, and there is a risk that the entire system cannot operate due to computing crashes or damage from major earthquakes.
