Abstract: 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.
