摘要
利用统一的GPS时间信息进行高精度时间同步,可以有效解决地理分布的半实物仿真系统的同步控制问题。针对RTX环境下GPS时间信息的实时采集问题,提出并设计实现了基于RS232串口读取时间信息报文和精确对时脉冲的时间同步方法。实践结果表明,该方法对时精度可达微秒级,满足了分布式半实物仿真系统的时间同步需求。
In order to run HIL simulation system synchronously, GPS time is used for time synchronizing in each simulation node. To get GPS time information precisely in RTX environment, a method of time synchronizing was designed, which get accurate GPS time pulse and relevant time information based on RS232 serial port. The experimental results showed that this method can make the outputing second pulse reach microsecond, and meet the time synchronizing requirements of distributed HIL simulation system.
