AI Technical Summary

Technical Problem

In the event of a sudden flood in a mountainous area, where roads, internet, and power are cut off, existing communication systems are unable to effectively notify people to evacuate, leading to loss of life or property.

Method used

Design an emergency call system that uses a LoRa communication module to achieve self-organizing network, including a call button and an alarm. The system can trigger warning commands in the event of a network outage via a button module, operate in the event of a power outage using battery power, and autonomously build a wireless communication network to achieve communication.

Benefits of technology

In the event of road, network, or power outages, it can quickly and accurately notify personnel to evacuate, ensuring the reliability and timeliness of information transmission and avoiding communication interruptions caused by infrastructure failure.

Abstract

This application discloses an emergency call system for extreme environments, relating to the fields of emergency communication and public safety. The system includes a call button comprising a first main control unit and button modules, a first battery, and a first LoRa communication module all connected to the first main control unit; an alarm comprising a second main control unit and audible and visual alarm modules, a second battery, and a second LoRa communication module all connected to the second main control unit; each second LoRa communication module is connected via a self-organizing network; the first LoRa communication module is connected to one or more second LoRa communication modules; the button modules are used to trigger the first main control unit to send warning commands to each second main control unit via the first LoRa communication module in the event of a network outage, and the second main control units are used to control the corresponding audible and visual alarm modules to sound an alarm. This application can notify personnel to evacuate in the event of a circuit outage, network outage, or power outage.
