| Abstract: |
| Along with the development of big data applications,getting data from the circuit switched domain is an important way to enrich the massive database.In order to improve the efficiency of circuit switched domain acquisition and enrich the collection means,according to the characteristics of circuit switched domain data requirements and data packet,an exchange field data acquisition circuit based on FPGA design is proposed,FPGA data model is given and the modules of the model are described in detail.The automatic conversion from circuit switched domain data to the packet switched domain is realized.Test results show that the data acquisition system enriches the time division multiplexing(TDM) line efficiency of data collection,and achieves the desired function. |
