针对现有舰船数据获取精度不高、通用性不强的特点,研究基于舰船综合平台的精确同步数据获取技术。利用GPS/北斗双模授时方案保证主时钟稳定性的同时,通过IEEE1588精确授时进行主从时钟同步,完成对从时钟的修正,保证各节点间高精度同步秒脉冲信号的输出。测试结果表明,该方案得到的秒脉冲信号最大偏差不超过500 ns,极大提高了综合平台各节点的同步精度。改进的通用性接口提高了各装置之间的互联性和综合平台的可控性。

For improving the accuracy of data acquisition and universality of the integrated platform management system, a method to acquire the precise data based on the system is proposed. By taking advantage of the signal generated either by GPS or Beidou,the accuracy of the master clock can be ensured, afterwards the slave clock can be modified by synchronizing with the master with the precise time protocol, each node outputting the pulse-per-second signal with high precision. Simulation and test results shows that this method can provide signal with the offset less than 500 ns, not only the problem of measurement accuracy is resolved, and the universality make it possible that parts become connected more closed and the integrated platform management system can make more accuracy control.
