LED earthquake early-warning emergency light with multi-color identification, digital intensity display and countdown

Abstract

The invention discloses an LED earthquake early-warning emergency light with multi-color identification, digital intensity display and countdown. A main PCB is connected with a full-color LED display screen, a sound alarm and an early-warning emergency light, and a main processor, an RF module, a voltage stabilizing module, a voice module and a driving module are welded onto the main PCB. The LED earthquake early-warning emergency light with multi-color identification, digital intensity display and countdown can play an automatic emergency illumination role during power failure, the RF module receives a data signal from an earthquake early warning server or an exercise signal from a remote control switch, and transmits data to the main processor for processing, the main processor controls the LED display screen, the sound alarm and the early-warning emergency light via multiple interfaces, the LED display screen displays the intensity color of earthquake intensity, the earthquake intensity number and countdown, the sound alarm emits different early-warning sound alarm according to the earthquake intensity, emergency illumination is started at the same time, and requirements in multiple aspects can be met.

Description

technical field [0001] The invention relates to the technical field of earthquake emergency early warning devices, in particular to an LED earthquake early warning emergency light with multi-color signs and digital display of intensity and countdown. Background technique [0002] At present, the country is building an earthquake early warning platform at the national, provincial, and municipal levels. When an earthquake occurs, the seismic platform will calculate the location, time, and magnitude of the earthquake within a few seconds (collectively referred to as the three elements of an earthquake). The early warning platform can be calculated based on these three elements. Find out the coordinates of the range of seismic wave influence that can cause ground damage seismic intensity, and send information containing early warning data such as seismic intensity when arriving at the terminal and estimated time of arrival to the earthquake early warning terminal within the range...

AI Technical Summary

Problems solved by technology

[0003] If an earthquake occurs, the power failure emergency lights in safe evacuation channels in schools, hotels, shopping malls and other public places have a single function, only have the temporary lighting function of power failure, and cannot play more roles and functions in emergency situations such as earthquake disasters. When an earthquake occurs, Emergency lights can only provide lighting. People in a panic cannot know the source of the earthquake, the size of the earthquake, and the impact and time of the earthquake on the local area. People will cause unnecessary losses in a panic situation.
