Analysis of time difference in quasi-synchronous acquisition of shallow seismic data and its practice;

Data acquisition equipments of weapon system and true value measuring equipments of the base would perform data synchronous acquisition work according to relevant test methods.

The design concept and circuit structure principle of high speed data synchronous acquisition and transmission system are introduced, which is used for the on line detection system for detection PD in power transformer.

A synchronous sampling system of AC electric signals in different places based on DSP and GPS;

The synchronous sampling of AC data of power system is of great significance to relay protection, fault diagnosis, system stability analysis and control as well as the parameter measurement of transmission line under operation etc.

A synchronous sampling system of AC electrical signals is designed based on PC104 industrial control computer and DSP.

The system combines the real synchronized collection of the force data plus image and the image series deformation analysis to measure the steel strand maximal load stretching,which overcomes the prob.
