Design of armed police sentry linkage alarm system based on STM32, supporting Ethernet and WIFI communication (hardware, source code, papers, etc.)

The armed police alarm information system terminal proposed in this article can realize alarm and linkage response, supports two communication modes of Ethernet and WIFI, and can realize mobile sentry alarm and fixed sentry alarm. The voice and display alarm information can be customized by users.
This terminal is mainly composed of STM32F103 processor module and C8051F340 processor module. The STM32 processor extends MP3, LCD touch screen, SD card, LED, buttons, relays and other sub-modules. It is mainly responsible for detecting key input, generating/parsing communication protocols, reading To retrieve stored file data, implement three-dimensional alarms, control external devices, etc., the C8051F340 processor has expanded the Ethernet communication sub-module and WIFI communication sub-module, which is mainly responsible for receiving and sending alarm data, and transmits it to the STM32 processor through the UART interface communication data.
