异构总线的多Agent网关设计与应用

摘要

Aiming at mismatching of different interface bus in heterogeneity sensor network, it is developed that the multi-Agents of gateway based on multi-system and μC/OS-Ⅱ, which imitates “ post” system.Some of the multi-Agents are “post service” Agents,which are responsible for I/O of a bus and exchanged with the post office, the one except “post service ” Agents is a “post office ”Agent, which is responsible for classifing, identifing, decrypting, encrypting the receiving messages from “post service ” agents,and transmit its to “post service ” Agents.The gateway program with embed multi-Agents of “post” structure are designed.The embed gateway is applied to the heterogeneity sensor network including a LPC2239 chip, AT89S52 chips and heterogeneity bus.It is effective for the on-line monitor in the mountainous area sensor network environment.%对现有各种传感检测对象建立传感监测网络时,出现多种异构总线不匹配的情况,研究提出了基于μC/OS-Ⅱ的"邮政交换体系"多Agent嵌入式网关模块设计思想,其中"邮政所"Agent管理一种总线的输入与输出,中心"邮局"负责接收"邮政所"Agent的数据消息,进行分类辨识,并分发到对应的"邮政所",实现嵌入式"邮政"体系的多Agent协调,并管理各异构总线的数据交换.将该嵌入式"邮政"体系设计应用到以LPC2239芯片及扩展多个异构总线硬件平台上,并编写了相应软件,将其运行在山区道路环境的在线监测网络上,效果非常好.
