Sensor data intelligent collecting system for navigation system

The invention discloses a sensor data intelligent collecting system for a navigation system. The system can preprocess the collected sensor data prior to transmission to improve the anti-interferenceability of the collected data and have a certain error compensation capability, the preprocessing process does not need a remote main control processor for intervention, the system is integrated witha full-duplex and dual-redundant high-speed asynchronous serial interface with RS422 level so as to complete high-reliability and high-speed transmission and update of the inertial sensor measurementdata and facilitate timely navigation resolving task of the CPU. 本发明公开种面向导航系统的传感器数据智能采集系统，对采集得到的传感器数据在传输前即可进行预处理，提升了采集数据的抗干扰能力，且具有定的误差补偿能力，预处理过程不需要远端主控处理器干预，系统集成有RS422电平的全双工双冗余高速异步串行接口，完成了对惯组传感器测量数据高可靠、高速的传输及更新，便于CPU及时进行导航解算任务。
