Design And Implementation Of Embedded TCP/IP Stack Based On VxWorks

Based on optimize estimate methods and centered on electronic computer, a system which combined some of whole navigation equipments on carrier into one organic system was called integrated navigation system(INS). This kind of integration method can enhance the precision of navigation data and extend the functions of single equipment or subsystem.Taking XXX integrated navigation display and control console as the background. According to the function and characters of XXX integrated navigation display and control console, this paper designs an embedded TCP/IP stack base on VxWorks 5.4 OS.Firstly, the paper introduces the embedded system software development technique, include the constitution principles and characters of RTOS detailedly, discusses VxWorks and it's integrated development environment Tornado carefully. Secondly it introduces principle and functions of Realtek 8019AS chip, finishes the driver of double interface Ethernet board. Finally it introduces the knowledge relating to TCP/IP protocol , designs the embedded TCP/IP stack according to character and function of XXX integrated navigation display and control console, illustrates the thought and method of embedded TCP/IP protocol and defines the modules of the protocol stack. Then it analyzes the relation and the interface of the modules and discusses the design and implementation of all modules detailedly. Redundancy backup communication of network under XXX integrated navigation display and control console is successfully solved, which enhanced the reliability of data exchange.
