The invention discloses a hard disk automatic switching device based on FPGA and an application method thereof. The device comprises a hard disk group; an embedded controller connected with each harddisk in the hard disk group; an FPGA in communication connection with the embedded controller; an MCU connected with the FPGA through an SPI bus and used for controlling and monitoring the working state of the hard disk pack; wherein the MCU is in communication connection with remote monitoring equipment through an Ethernet protocol conversion chip so as to receive corresponding starting and/or switching control signals. The invention provides an automatic hard disk switching device based on an FPGA, which can select a starting hard disk through remote control and automatically switch to another starting hard disk to realize normal starting when the default starting hard disk has a fault. 本发明公开了一种基于FPGA的硬盘自动切换装置及其应该方法，包括：硬盘组；与硬盘组中各硬盘相连接的嵌入式控制器；与嵌入式控制器通信连接的FPGA；通过SPI总线与FPGA连接，对硬盘组的工作状态进行控制、监测的MCU；其中，所述MCU通过以太网协议转换芯
