Product Details

Working Principle

Its core logic is "low-power standby + quick trigger + multi-channel communication + linked response". Key process:
1. Standby: In super low-power sleep mode when not triggered, with regular self-tests for abnormalities.
2. Trigger: Press and hold the SOS button (2-3s anti-misoperation) or pull the rope to wake up the main control MCU.
3. Positioning & Signal: MCU starts positioning (indoor: base station+WiFi; outdoor: GPS/Beidou) and encrypts device information into alarm packages.
4. Push: Alarm data is sent to local hosts, APPs, short messages and cloud via 433MHz, NB-IoT or 4G.
5. Response: Receiving end triggers alarms, notifications and calls, forming a "trigger-push-response" loop.
6. Recovery: Returns to sleep after rescue or false alarm cancellation, resends signals if abnormal.
