Low-delay and high-reliability attitude information data processing method

The invention relates to a low-delay and high-reliability attitude information data processing method. A signal is received and converted through a high-speed optical fiber interface; performing data source selection switching control on the converted signal, and outputting heading, pitching and rolling data in parallel; carrying out limiting processing and channel conversion on heading, pitching and rolling data; and synchronously outputting the signal after limiting processing and channel conversion. Attitude information sent by a sensor is received through a high-speed optical fiber interface, after source selection processing is conducted on the information in equipment, low-delay high-reliability interface design is adopted, and ship course, pitching and rolling information is sent to a user through a double-channel solid-state analog quantity interface. 本发明涉及一种低延时高可靠性的姿态信息数据处理方法，通过将信号通过高速光纤接口进行接收和转换；对转换的信号进行数据择源切换控制，并行输出航向、纵摇和横摇数据；对航向、纵摇和横摇数据进行限位处理和通道变换；同步输出限位处理和通道变换后的信号。本发明通过高速光纤接口接收传感器发送的姿态信息，设备内部对信息择
