Study on Interface between Multi-serial Port and Ethernet
Zhao Ai-qi · Value Engineering · 2012
In a weapon system,an interface between Ethernet and four serial port is needed,so a transfer device is developed.The hardware is based on ARM-11 named S3C6410,and modbus protocol is employed,UDP is adopted in net.Under the Linux operation system,data transfer between serial ports and Ethernet is achieved,especially,when net is broken,system can check the weapon,and then saves the data in Nand-Flash.When net is connected,system can reads the data from Nand-Flash,and send it to control center.System testing results are also demonstrated in detail.
