摘要
针对目前深远海试验场建设过程中,探测装置通常搭载多传感器进行水下信息采集并上传数据至海面趸船的计算机中,其中,多探测设备上传数据由于采样频率不同步容易导致数据频谱分析后误差加大问题,提出了一种基于DP83640同步以太网使能模式方法,提高采集数据的稳定性和精确度,文中阐述了系统设计、时钟同步方案,并给出了典型的试验验证结果。
In the deep sea test field construction,detection device is usually equipped with multisensor for environmental information collection under water,and upload the data to the computer in the sea barge.Aiming at the error situation of data analysis is easy to increase by multiple exploration equipment,because of the different sample rate.A new method of DP83640 synchronous ethernet mode is proposed for increasing the data collection stability and accuracy.This paper describes the system design and clock synchronous scheme,and typical test the results are giren.
