Description

Technical Field

[0001] The utility model relates to the technical field of earthquake alarm and emergency disposal, in particular to an earthquake early warning switch. Background Art

[0002] With the acceleration of urbanization and the popularization of high-tech equipment, the demand for earthquake early warning systems is increasing. Traditional earthquake early warning systems rely on the monitoring of seismic waves, but such systems often have problems such as long response time, complex data processing, and low warning accuracy. In addition, traditional systems often lack effective data storage and remote transmission functions, which limits the further analysis and utilization of earthquake data. In order to solve these problems, modern earthquake early warning systems have begun to use high-precision MEMS digital accelerometers for real-time monitoring of seismic waves and fast data processing through integrated single-chip microcomputers. However, the design of these systems is often complex and costly, and in practical applications, they still face the challenge of improving warning accuracy and reducing system response time.

[0003] The Chinese patent with publication number CN209607117U discloses an intelligent earthquake alarm, which detects the vibration of the ground through an earthquake detection circuit, thereby providing an early warning and reducing the losses caused by earthquake disasters. However, the alarm is mainly limited to earthquake detection and sending early warnings wirelessly, and its functions are relatively simple. It does not save earthquake data for subsequent predictions, and only sends early warnings through a wireless network. If the wireless network fails, there is no alternative plan.

The SWD interface is widely used in programming and debugging microcontrollers due to its simple lines and efficient data transmission performance. Through this interface, developers can handle firmware updates and fault diagnosis more efficiently during the development and maintenance phases.
