Embedded disaster monitoring device

The invention discloses an embedded disaster monitoring device, which adopts a modular design and comprises a baseboard module, a master control board module, an RS485 module, a switching value input module and a switching value output module. The integral structure is a controller area network (CAN) bus structure, and a double-redundant CAN bus is used to improve the reliability and safety; various board cards of the device are pluggable, and realizes hot plug function; the master control board module and sub-board modules adopt hot standby technology to ensure that the device can continuously, safely and reliably complete preset functions; in the device, an embedded Advanced RISC Machine (ARM) chip is adopted as a central processing unit (CPU) of a master control board, an AVR singlechip is adopted as a CPU of each sub-board, and uClinux is adopted as an operating system; an Ethernet interface is integrated so as to communicate with a server, and an RS232 interface is integrated to communicate with an upper computer; and the embedded disaster monitoring device has voltage monitoring and failure warning functions.
