Abstract: The test platform was implemented with Socket communication method for GPRS industry control network, and the time-delay of the GPRS industry control network was tested and analyzed by TCP and UDP protocols. The guiding opinion was given in the field application. On the basis of time series theory, the time-delay of GPRS industry control network was predicted by using the LS-SVM optimized by PSO. The simulation results showed that the proposed method could very well predict the time-delay of the GPRS industry control network. It also provided a good foundation for the following network predictive control.
