This paper introduces the design and implementation method of an intelligent alarm with remote control function using ESP32 as the core.Its hardware functional units include Wi-Fi,Bluetooth,memory,FM radio,charging OTG,and speakers.It mainly implements IPAWS alarm push function and FM listening function in case of network interruption and power outage.It supports connection with mobile APP and can respond to remote client control commands.The interaction between devices is controlled through AWS-IoT,and the firmware file of the alarm is remotely upgraded using OTA technology.The IPAWS system achieves a unified source of warning information and diversified means of dissemination through point to surface communication,which can effectively expand the scope of user use.
