Emergency SOS system with two-way voice communication function

Abstract

An emergency rescue system with two-way voice communication capability includes a microcontroller, a distress button, a wireless communication module, a voice processing module, and a remote alarm device. When personnel are trapped in enclosed spaces such as cold storage or equipment rooms, pressing the distress button triggers the microcontroller, which then uses the wireless communication module to transmit a distress signal to the remote alarm device via long-range wireless communication technology (LoRa) to issue an alarm. Subsequently, the trapped personnel and external personnel can conduct two-way voice communication through the voice processing module, enabling rescuers to quickly grasp the situation of the trapped person and carry out rescue operations, significantly improving the safety of the working environment.

Claims

1. An emergency distress system with two-way voice intercom function, comprising a microcontroller, a distress button, a wireless communication module, a voice processing module, and a remote alarm device, wherein: The output of the distress button is electrically connected to the input of the microcontroller to send a trigger signal; the output of the microcontroller is electrically connected to the wireless communication module, which uses wireless transmission technology to communicate with the remote alarm device; the voice processing module is electrically connected to the microcontroller for audio capture and playback; the remote alarm device forms a wireless connection with the wireless communication module to receive distress signals and trigger alarms, and also has voice communication functionality.
