Aiming at the problem of synchronous data acquisition for experiment of submerged floating tunnel,a high-precision synchronization data acquisition system has been designed from three aspects:10 Gigabit fiber optic networking,synchronous data acquisition control,real-time data access and intelligent judgment.The system has designed a 10 Gigabit optical fiber networking solution to improve network transmission efficiency and stability,and proposed an NTP-based time synchronization acquisition control and deviation estimation method to solve the time-coaxiality problem of high-precision model experiments.In addition,the system has designed real-time data access and intelligent judgment strategies based on a separation of four databases to achieve automatic extraction of characteristic data under specific working conditions.The results show that the system satisfies the time accuracy requirements for precise control of submerged floating tunnel model experimental,and the collected data conforms to the principle of repeatable and reproducible experiments.
