Smart Fire Safety

This block diagram shows the hardware schematic of smart fire safety equipment with GD32F527 as the main MCU. On the left, peripherals including LCD TFT, USB, RTC and SDRAM are deployed, and a CAN transceiver connects to the CAN/LIN bus. The right side integrates diverse communication and storage interfaces: Ethernet links to RJ45 port; two UART channels connect a 2G/4G module and GD32VW553-MINI wireless module supporting Wi-Fi 6 + BLE 5.2 respectively. I2S extends GPIO control ports, and SPI is used for external Nor Flash memory. Equipped with complete interfaces, this solution supports HMI, multi-channel wired & wireless communication, bus signal collection and local storage, perfectly fitting various intelligent fire monitoring and alarm terminals.
