基于SD卡舰舵参数采集传输系统设计

Design of the Autopilot Parameters Acquisition and Transmission System Based on SD card

针对目前VDR中舰舵参数的提取困难问题,设计一种以C8051F500单片机为主控制器,SD卡为安全存储介质,GPRS-DTU为传输设备的采集传输系统,实现对舰船自动舵的航向、舵角、位置等参数的采集、存储和传输,为舰船运动模型参数辨识提供实验依据,并能优化自动舵的控制率。

Aiming at the difficulties in the parameters extractions of ship autopilot from VDR are more , an acquisition and transmission system of autopilot parameters is designed based on C 8051F500 as the microcontroller , SD card as the secure storage medium and GPRS-DTU as the transmission equipment .The system can acquire , store and transmit the parameters such as ship autopilot heading , rudder angle , position and so on , so as to provide experimental evidence to identifying the parameters of the ship motion model and optimize autopilot control rate .
