The Design And Implement On The Embedded Uart-Network Protocol Conversion

The Embedded UART-network protocol conversion machine is a kind of small equipment to receive the data through the UART, to throw-over the date through the TCP/ IP stack, then to send out the data through a network,which make data can be deliver in the calculator network.It is so fast The INTERNET develop that the applied credibility of network has already can satisfy the request of each realm.Therefore, to make use of the scope that the network extension data deliver, person- machine that carries out the long range hands over to control with each other, is a inevitable trend for the technique development automate the technique and industries to measure and to control. The development of equipments of The Embedded uart-network protocol conversion machine also exactly is according to the applied background.It is designed that the hardware system structure of 32 processor LPC2294s for the protocol conversion machine in the document, and it is studied that how to replant the real operate system of μ C/OS-II of transplantation for the ARM7TDMI-S on the processor, and it is designed that the UART drives and the network data exchanges to send out application layer processing procedure. It is replanted that a net card drives and a Embedded protocol stack ZLG/IP. In the end, it is builded up the cross and develop terrace for the ADS1.2 integration development environment.This thesis mainly includes six parts and appendix.First, it is explained the research circumstance of current some stack conversion machine, analyze to negotiate the trend of convert the machine development in the future.The second part, it is studied the function of the processor of LPC2294, ROM and RAM to look for the address, function of UARTO, with the conjunction constitution of the RTL8019 net card chip, put forward the structural design project of the hardware system.The third part, it is introduced the basic principle of the real operate system of μC/OS-II, modify to among them transplant the document need, the first floor that designs to make to processor connects, the plait wrote the start code.The fourth part, it is designed a reenter connect function of API for the UARTO, the transmission brigade row, a reenter connect function of API forthe RTL8019 net card, and it is designed that the UART drives .
