(The TCP/IP protocol ensures the accuracy of data transmission on the Internet, and how to use the TCP/IP protocol to terminate the single-chip network communication in the field of data collection and control has far-reaching implications. A specific termination scheme for communication between single chip microcomputer and Internet network is proposed, relying on the Ethernet control chip RTL8019AS. The TCP/IP protocol is embedded in the general-purpose single-chip microcomputer, and the intelligent equipment and appearance are terminated through RTL8019AS.)
