Other AbstractThe invention relates to a microcontroller-based fan overspeed protection device and a safety chain action method. The microcontroller-based fan overspeed protection device comprises a microcontroller, an optocoupler, a coding switch, a serial level switching chip, a triode and a relay. The safety chain action method comprises the following steps of: initializing the microcontroller reading an overspeed set value calculating an actual rotating speed value and judging whether overspeed occurs. The detection precision of the microcontroller-based fan overspeed protection device exceeds that of the existing FPGA (Field Programmable Gate Array) by 0.1Hz and reaches 0.01Hz and the microcontroller-based fan overspeed protection device brings the convenience for embedded expansion, and is capable of outputting real-time data for bringing the convenience for data analysis.
