说明：  To meet the monitoring requirement of the high real-time remote control system , an implementation method of embedded TCPIP protocol stack LwIP on ROS33 OS is described in this paper. Based on the hardware platform combining, microprocessor S1C33E07 with Ethernet controller DM9000A, the transplantation of LwIP 1.3.2, and the drivers realization have been introduced in detail. Test results have shown that the designed system can communicate by Internet accurately and steadily
