Description

Technical Field

[0001] The utility model relates to an earthquake early warning service terminal, in particular to an outdoor earthquake early warning service terminal based on PLC power supply. Background Art

[0002] Earthquakes are a common natural disaster, and it can be said that they are the top disaster. Earthquakes are often caused by tectonic movements and plate collisions inside the earth. The energy released by earthquakes will cause ground vibrations of varying degrees, causing hazards such as ground shaking, building collapse or ground subsidence. The greater the magnitude of the earthquake, the more serious the casualties and disaster losses caused by the earthquake. If a risk avoidance alarm message can be issued before the earthquake's transverse waves arrive and cause serious casualties, the degree of the disaster can be greatly reduced. This is earthquake early warning. The principle is to use the fact that the propagation speed of electromagnetic waves is much greater than the propagation speed of seismic waves, and to issue earthquake early warning information in advance in certain areas.

[0003] At present, the construction of earthquake early warning engineering projects has been carried out nationwide. In addition to some common devices such as mobile phones, televisions and radio stations that can be used to issue early warning information, there is also a type of outdoor dedicated early warning release terminal. It needs to be powered on for a long time. Once the early warning information is received, it can send out an alarm message to the outside. Compared with mobile phones or televisions, this type of outdoor terminal is easier to send out early warning information in a timely manner. Patent CN220820818U (application number: 202321874063.0) discloses an outdoor installed earthquake early warning broadcasting device, including a shell, the interior of the shell is used to install an alarm module. By improving the earthquake early warning broadcasting equipment, the technical problem of the inconvenience of outdoor installation of the equipment is solved, and the technical effect of improving the convenience of installation of earthquake early warning broadcasting equipment is achieved. Although patent CN220820818U improves the installation convenience of early warning broadcasting equipment, in areas where power outages occur due to power failures, the early warning terminal equipment will be completely unable to work, affecting the timely broadcast of early warning information.
