AI Technical Summary
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.
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.
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.
