Single-channel communication method and device for multi-axis fiber-optic gyroscope

The embodiment of the invention provides a one-way communication method and device for a multi-axis fiber-optic gyroscope. Each axis of the multi-axis fiber-optic gyroscope is that a data signal levelMAX3490 sent by a respective FPGA into a level in an RS422 form, wherein the MAX3490 has transmitting and receiving functions, and the data of other paths of gyroscopes are transmitted from TX ends of respective MAX3490 chips to any specified path of RX end of the multi-axis fiber-optic gyroscope, and then data combination is carried out by the FPGA of the path, and then the real-time data of themulti-axis fiber-optic gyroscope is serially transmitted from the path. The single-channel output mode is that the angular rate bytes of the multiple gyroscopes are framed and synchronously sent outand sent to the receiving terminal, so the number of needed hardware is reduced, and the receiving terminal can conveniently process the next step of data. 本发明实施例提供一种多轴光纤陀螺单路通信方法和装置，多轴光纤陀螺的每一轴均为各自FPGA送出的数据信号电平MAX3490转换为RS422形式的
