摘要
为解决船岸通信带宽不足导致的船岸信息传输受限的问题,提高船岸数据交互效率,提出一种基于改进的消息队列(Messages Queue,MQ)协议的船岸信息交互方案。针对单一通信方式带宽不足和覆盖区域不全的问题,提出多种通信模式自动识别和自动切换的船岸通信方法,并给出不同船舶运营场景下的通信策略;针对船舶系统间数据交互信息量较大,易出现数据处理不及时和丢失的问题,对MQ通信技术进行改进,提出流量削峰技术方案。以某化学品船的船岸一体安全监控系统数据交互为例验证该船岸信息交互方案的可行性,设置网络连接状态模拟不同的通信场景,设置不同的数据传输频率模拟数据传输的带宽压力,结果表明该方案能有效解决数据丢包问题,缓解计算资源压力,提升信息传输效率。
In order to improve the efficiency of ship-shore information transmission,an integrated ship-shore communication solution based on an improved MQ(Message Queue)protocol is developed.A ship-shore communication method that features multiple communication mode automatic recognition-switching is introduced to address the issues of insufficient bandwidth and incomplete coverage area of a single communication method.Meantime,communication strategies for different ship operation scenarios are proposed.In response to the large amount of data to be exchanged between ship systems MQ communication technology with algorithm improvement and a traffic peak shaving technology scheme are introduced,which improves the communication reliability and Immediacy.The ship-shore information exchange scheme is tested on the ship-shore integrated safety monitoring system of a chemical ship to verify its feasibility.Different communication scenarios is simulated by setting network connection status and the bandwidth pressure of data transmission is simulated by setting different data transmission frequencies.The test results show that this scheme can effectively solve the problem of data packet loss,alleviate the pressure on computing resources,and improve information transmission efficiency.
