High-accuracy multipath data synchronous acquisition device

The invention provides a high-accuracy multipath data synchronous acquisition device and relates to a high-accuracy multipath data synchronous acquisition technology. In the high-accuracy multipath data synchronous acquisition device, the GPS pulse-per-second signal output end of the a GNSS device is connected with the GPS pulse-per-second signal input end of a high-accuracy multipath time service module, the high-accuracy multipath time service module comprises multiple level pulse-per-second signal output ends, one level pulse-per-second signal output end is connected with a standard device, and other level pulse-per-second signal output ends are connected with tested devices. The high-accuracy multipath time service module further simultaneously sends a TTL level pulse-per-second signal to an industrial control mainframe through a high-speed optical fiber serial bus. The standard device and the test signal output ends of the tested devices are respectively connected to one test signal input end of an interface module. The synchronous performance of the high-accuracy multipath data synchronous acquisition device can be remarkably improved, hardware integration can be further improved, the size is greatly decreased, the information transmission rate and reliability are improved, a memory device has a shake-proof function, and the high-accuracy multipath data synchronous acquisition device is suitable for testing of a ship system.
