采集终端在线动态修改IP地址研究与应用

Research and Application of On-line Dynamic Modification of Address in Acquisition Terminal

采集终端通过以太网与主站通信,根据主站命令及时修改终端IP地址是当今智能化时代的需求。本文设计了基于LPC1788嵌入式微控制器、片外NandFlash和DP83848网络接口的采集终端动态修改IP系统。经过程序调试和实验测试,终端不需要断电再上电或复位,不影响网络模块以外其它模块的正常工作,仅需1s延时,终端即可更换新的IP,主站便可以新的IP访问采集终端。系统操作方便,结构简单,减少了管理员的操作量,减小了输入错误的可能,具有较高的实用和推广价值。

The acquisition terminal communicates with the master station through Ethernet and it is the demand of the age of intelligence to modify terminal IP address in time according to master command.In the paper,a system named dynamic modification of the acquisition terminal＇s IP address is designed,which is based on LPC1788 embedded microcontroller,out-of-chip NandFlash and DP83848 network interface.After the program debugging and experimental test,the terminal does not need to power off and power again or reset,what＇s more,it does not affect the normal work of other modules outside the network module.With only one second delay,the terminal can replace the new IP,and the main station can access the acquisition terminal with the new IP.The system is easy to operate,simple in structure,reducing the operation of the administrator and the possibility of input error.It has higher practicability and popular value.
