Description

TECHNICAL FIELD

[0001] The utility model relates to the field of earthquake early warning technology, concretely to an earthquake early warning emergency broadcast system with a shouting function. BACKGROUND

[0002] Earthquake early warning refers to giving an alarm to a fortification area for several seconds to dozens of seconds before a seismic wave propagates to the fortification area after an earthquake occurs, so as to inform the local people to take emergency measures and reduce casualties and losses as much as possible.

[0003] The principle of earthquake early warning is to use the characteristic that the propagation speed of a seismic wave is less than the propagation speed of an electric wave. When an earthquake occurs, two main seismic waves are generated: a longitudinal wave (P wave) and a transverse wave (S wave). The longitudinal wave propagates at a high speed, but has a small destructive power; the transverse wave propagates at a low speed, but has a large destructive power. An earthquake early warning system receives the data of the first-arriving longitudinal wave, quickly estimates the basic parameters of the earthquake, and predicts the influence on the surrounding area, so as to publish early warning information to the area that may be affected before the transverse wave with strong destructive power arrives.

[0004] After searching, the patent with the application number CN202321963300.0 discloses a service terminal with emergency broadcast and earthquake early warning functions, which comprises a terminal body and a pre-buried box. The pre-buried box is embedded in a wall, and the terminal body is embedded in the pre-buried box. The wall is embedded with a wiring pipe, and the wiring pipe is provided with a cable connected with the terminal body. The cable is used to connect an external antenna. The terminal body comprises a shell, a display screen and a loudspeaker. The display screen and the loudspeaker are fixedly connected to the shell. The side of the pre-buried box is further connected with a power box, which is embedded in the wall. The power box is connected with an adapter electrically connected with the terminal body. The application improves the reliability of the household earthquake early warning device by improving the installation position and structure of the earthquake early warning device.

[0005] The current earthquake early warning emergency broadcast system generally only has two broadcast modes: real-time voice broadcast and audio broadcast of earthquake information. The dispatch center personnel need to shout to the on-site staff and communicate in real time through a remote terminal, and repeatedly broadcast and convey the earthquake information. For a large amount of text information that needs to be conveyed and the on-site staff cannot read immediately, the communication efficiency and emergency response speed are reduced. Therefore, we need to propose an earthquake early warning emergency broadcast system with a shouting function. UTILITY MODEL CONTENT
