Abstract


In recent years, weapons systems widely used classes such as 1553B , CAN , Ethernet , and other industry-standard bus control , storage testing , data acquisition , control agencies or black box test recording system process large amounts of data requires accurate , confidential transmission and storage . Field operations in harsh and hazardous environments , such as explosion testing , often due to the computer impact damage caused by the loss of all important data . If the outside of the computer security zone reliable storage equipment and computer interconnection real-time data transmission and storage backup can solve this problem , put forward new demands on the transmission rate and transmission distance . With the leadership of the development of Ethernet technology it fieldbus and may become the only industrial control network standard digital interface is a dominant trend . Connect it flexible , open and versatility , and not at the expense of transfer speed at the expense of long-distance data transmission , but to use efficient network transmission characteristics , both to expand the scope of the transmission distance was greatly enhanced by the transmission speed . This study is the use of an Ethernet interface to achieve real - time data transfer is a good solution , get rid of the impact of distance is limited , can be up to 100 meters away from the danger point to improve the security of the data backup . Design for Ethernet protocol in the computer communications applications is relatively complex , the hardware implementation of more complicated problems , launched an exploratory research on the the Ethernet Storage instrument system integration issues . Papers by research Ethernet data transmission protocol select UDP protocol suitable for the requirements of this topic ; design a simple and reliable hardware system integration solutions , composition of the FPGA as the core collection of the FLASH memory , Ethernet chip , USB control integrated experimental prototype chip modules and VHDL hardware description language to design a new parallel structure, the function of FPGA programming and multi - level simulation and system state machine simulation ; design the PC software , Ethernet transmission the storage experiments show that the study is feasible to achieve the expected requirements .
