Earthquake alarm system and device based on wireless Internet of things

Abstract

An earthquake alarm system and device based on a wireless Internet of things are characterized in that the system and device comprise an Internet-of-things control unit and a plurality of pieces of earthquake alert and alarm equipment with wireless transmitting modules. The Internet-of-things control unit is built on a 4G wireless network platform. The Internet-of-things control unit comprises anMCU module, a Zigbee wireless network terminal, a Zigbee wireless network coordinator, a short message alarm, a central controller, a 4G module, mobile terminal equipment and a power supply. The Zigbee wireless network coordinator is connected with the central controller, the central controller is connected with the short message alarm, and the short message alarm is connected with the mobile terminal equipment through the 4G module. The earthquake alarm system and device have the advantages of simple structure and high sensitivity. The earthquake alarm system and device can send a wireless alarm signal or a sound-light alarm signal to relevant workers in time before an earthquake, so that people have enough time to evacuate, and the damage of earthquake to people is reduced.

Description

technical field [0001] The invention relates to an earthquake early warning device, in particular to an earthquake and alarm device based on a wireless Internet of Things platform, simple in structure, high in sensitivity, and capable of detecting longitudinal waves so that an alarm can be issued earlier. Background technique [0002] Earthquake, also known as ground motion, is a natural phenomenon in which vibrations are generated during the rapid release of energy from the earth's crust, during which seismic waves are generated. The compression and collision between the plates on the earth will cause the edge of the plate and the inside of the plate to displace and break, which is the main cause of the ground vibration (that is, earthquake). [0003] Earthquake disasters are extremely harmful, and occur frequently and suddenly, which easily cause huge losses to people's lives and property. Earthquakes often cause serious casualties and destroy engineering facilities such ...

[0003] Earthquake disasters are extremely harmful, and occur frequently and suddenly, which easily cause huge losses to people's lives and property

Earthquakes often cause serious casualties and damage houses and other engineering facilities, especially in public places and densely populated places, which are more likely to cause serious losses

Therefore earthquake reminding just seems particularly important, but the earthquake monitoring instrument of current earthquake prediction department is all complex in structure, and cost is expensive, is not suitable for use in places such as public place, family, just makes the early warning of earthquake lag behind the earthquake that takes place rapidly, makes people in When an earthquake occurs, you can't get timely and accurate reminders, thus wasting the golden 12 seconds when the earthquake occurred

[0004] The current seismographs generally exist in the form of a single individual and have not been connected to each other, so the prompting and alarming effects are relatively isolated, and timely and comprehensive reminders and alarming functions cannot be realized, and it is easy for people in danger to lose best time to escape
