摘要
嵌入式通信网络的运行环境复杂,降低了信息采集效率和通信网络协同控制任务性能。为了增强系统在复杂对抗环境下的协同性能,应提高系统的抗毁性。因此,采用LPC2290芯片作为微控制器,融合以太网模块、CAN模块、电源模块和相关外围接口模块,构建整个嵌入式通信网络系统。系统硬件电路结合子板和母板共同实现相关功能,提高系统的协同处理性能;采用基于Protocol_TCP协议的流套接子完成数据通信,增强通信系统的稳定性。依据嵌入式通信网络抗毁指标以及成本的最小化目标,设计网络抗毁性模型。将该抗毁性模型融入嵌入式通信网络自愈模型中,增强遭受攻击后网络的自愈能力,提高网络抗毁性能。实验结果表明,该设计系统具有较高的抗毁性,系统的吞吐量和平均时延性能较高。
The running environment of the embedded communication network is complex,which may reduce the efficiencyof information collection and performance of communication network coordination control task. In order to enhance the system col?laboration performance in complex confrontation environment,the system invulnerability should be improved. The chip LPC2290is taken as the microcontroller,and the Ethernet module,CAN module,power supply module and related peripheral interfacemodules are integrated to construct the whole embedded communication network system. The daughter board and mother boardare combined in the system hardware circuit to realize the related function together,and improve the coordination treatment per?formance of the system. The stream socket based on Protocol_TCP is used to accomplish the data communication,and improvethe stability of the communication system. On the basis of the invulnerability index of the embedded communication network andthe target of cost minimization,the network invulnerability model was designed. The invulnerability model is integrated into theself?healing model of the embedded communication network to enhance the self?healing ability of the attacked network,and im?prove the network invulnerability. The experimental results show that the designed system has high invulnerability,high systemthroughput and high average delay performance.
