摘要
在船舶航向运输新业态的"群落-分层-演替"中,以往使用的系统在无线信号收发控制下很难建立起同步机制,导致系统数据传输异常。为此,设计数据节点分布下船舶航向运输新业态的"群落-分层-演替"系统。考虑系统中的数据节点分布,选择LPC2378控制器作为节点的核心控制器,采用E30-TTL-100模块实现节点数据传输,在硬件设计的基础上,采用多跳的方式传输节点数据,计算最大时延确定数据聚合最佳时机,数据聚合完成即完成了信息群落的演替。测试结果表明:设计的"群落-分层-演替"系统在距离服务器远近2种条件下,其时延较低,数据传输正常。
In the community-stratification-succession of the new format of ship course transportation,the system used in the past is difficult to establish a synchronization mechanism under the control of wireless signal transmission and reception,resulting in abnormal data transmission.To this end,a"community-stratification-succession"system for the new format of ship course transportation under the distribution of data nodes is designed.Considering the distribution of data nodes in the system,the LPC2378 controller is selected as the core controller of the node.The E30-TTL-100 module is used to realize the node data transmission.Based on the hardware design,the node data is transmitted in a multi-hop mode.The maximum time is calculated.Determining the best time for data aggregation,the completion of data aggregation will complete the succession of the information community.The test results show that the designed"community-stratification-succession"system has low latency and normal data transmission under two conditions of distance from the server.
