In order to improve the reliability and transmission speed of the data editing and transmission system,a system of data editing and transmission based on localization is designed.The whole system takes the domestic FPGA as the control core and completes the instruction delivery and data reading of the upper computer through Ethernet.Finally,it connects to the acquisition module through high-speed serial communication and carries out data reading through Ethernet.The data reading speed can reach 600 Mb/s,which has been verified in the data recorder experiment of a monitoring console.By optimizing the communication mode,the transmission speed can reach 1.25 Gb/s.The IP multicast mode of the switch is mainly used to replace the point-to-point communication mode,so that the multi-platform machines can communicate with the data acquisition,transmission and storage system at different times and places,which improves the system flexibility and convenience,achieves the purpose of localization.
