Abstract

The invention belongs to the field of safety protection alarm, and relates to an emergency alarm system and an implementation method, in particular to a wearable emergency alarm system and method based on NFC near-field communication and LoRa low-consumption long-range communication technologies. The invention provides an intelligent alarm system which activates a wearable alarm device through a mobile phone NFC signal and sends an alarm signal to a monitoring background in a LoRa communication mode under the condition that a conventional communication environment is lacked or an emergency situation occurs. The wearable alarm device combining the NFC communication function and the LoRa node function has the advantages of low power consumption, long time efficiency, strong penetrating power, long communication distance, high response speed, strong concealment and the like, is suitable for rapid and continuous alarm under the conditions of natural disasters, safety crisis, severe livingenvironment and the like, and can be linked with a LoRa gateway carried on an unmanned aerial vehicle platform to meet the system requirements of emergency alarm, rapid positioning and rescue.

Description

technical field [0001] The invention belongs to the field of security protection and alarm, relates to an emergency alarm system and an implementation method, in particular to a wearable emergency alarm system and method based on NFC near-field communication and LoRa low-consumption long-distance communication technology. Background technique [0002] In many specific situations, the process of people sending out the alarm signal will encounter the great influence and limitation of the communication environment and the alarm time. In some cases, for example, the limitations of the communication environment, including the lack of mobile phone communication networks and satellite communication networks in extreme environments such as the wild, oceans and deserts, people cannot use conventional means such as mobile phones and navigation to call the police and call for help; In other cases, such as hijacking and coercion by criminals, emergency alarms require specific urgency an...
