Embodiment Construction

[0015] The invention discloses an LED display earthquake early warning system, which includes a cloud server and an LED display, and the LED display includes a controller, a display receiving module, a display sending module (receiving card) and a display content switching module.

[0016] Among them, the cloud server is used to store the region ID codes of all LED displays, to receive earthquake early warning information, and to extract the earthquake occurrence time, earthquake longitude and dimension for calculation and analysis, and to obtain the boundary information and propagation range of the province where the source of the earthquake is located; and then , the cloud server matches the area ID codes of all LED displays according to the boundary information and propagation range of the province where the source of the earthquake is located, and obtains a list of early warning LED displays; then, the cloud server sends the earthquake early warning information to the list o...

Abstract

An LED display screen earthquake early warning system of the present invention comprises a cloud server and an LED display screen, and the LED display screen comprises a controller, a display receiving module, a display sending module and a display content switching module. According to the LED display screen earthquake early warning system, when an earthquake occurs, information can be displayedaccording to a system program, so that people outdoors or in meetings can know and take effective protection measures, the difficulty of disaster relief work is reduced, and casualties are reduced andavoided.

Description

technical field [0001] The invention relates to the application field of LED display screens, in particular to an earthquake early warning system for LED display screens. Background technique [0002] The working principle of the earthquake early warning system is that when the initial earthquake is detected, the non-destructive seismic wave (longitudinal wave P) is emitted, while the destructive seismic wave (shear wave S) will be delayed by 10 to 30 seconds due to its relatively slow propagation speed. surface. At this time, the seismic detector detects the longitudinal wave P and transmits it to the computer to calculate the various parameters of the earthquake, and then transmits it to each end user through electromagnetic waves to give an early warning 10 to 30 seconds before the shear wave S reaches the ground. [0003] The existing LED display screens have been integrated into the streets and alleys, and the application scenarios include individual families, company ...
