【摘要】：由于运输周期长、环境恶劣,船载危险品集装箱极易发生事故,而且集装箱的封闭性及船上人员、设备的缺乏给事故的发现和处理带来了极大的困难,因此对船载危险品集装箱进行安全监测就显得尤为重要。目前,应用于公路、铁路运输领域的集装箱监测系统一般采用RFID、GPRS、GPS及GIS等技术,但这种系统的通讯方式、监测对象及监测系统结构并不适用于船载集装箱运输。近年来无线传感器网络技术发展迅速,并成为了船舶自动化的一个发展方向。自组织、低功耗、低成本等特点使无线传感器网络技术成为船载危险品集装箱安全监测较好的选择。本文从船载危险品集装箱安全监测的实际需求出发,设计了一种基于无线传感器网络技术的船载危险品集装箱监测系统,该系统主要包括无线传感器网络节点及监测中心数据管理软件。首先,在JN5148模块的基础上,设计了三种无线传感器网络节点的硬件电路,分别为协调者节点、路由节点和监测节点。同时,为解决危险品集装箱监测对象多且经常更换的问题,设计了“即插即用”的传感器模块,监测节点通过复用12C总线来识别和读取传感器模块。其次,在JenNet协议的基础上,设计了协调者节点、路由节点及监测节点的软件。除正常的组建网络及通信功能外,协调者节点具有串口通信、获取监测节点采集的数据等功能,路由节点具有保存监测节点采集数据、记录子节点状态等功能,终端节点具有识别传感器模块及采集数据等功能。再次,利用Visual Basic设计了危险品集装箱安全监测中心数据管理软件,该软件具有自动配置串口,数据接收及自动存储,系统运行状态及预警信息提示,数据曲线、表格显示,网络拓扑显示,历史数据查询及指令发送等功能。最后,对本文所设计的船载危险品集装安全监测系统进行了组网测试、数据采集测试及能量消耗测试。
[Abstract]:Because the transportation cycle is long, the environment is bad, the ship dangerous goods container is easy to happen the accident, moreover, the container closure and the ship personnel, the lack of equipment brings the great difficulty to the accident discovery and the processing. At present, the container monitoring system used in highway and railway transportation generally adopts the technology of RFID-GPRSU GPS and GIS, but the communication mode of this system is very important. The monitoring object and monitoring system structure are not suitable for shipborne container transportation. In recent years, wireless sensor network (WSN) technology has developed rapidly, and has become a development direction of ship automation. Low cost makes wireless sensor network (WSN) a better choice for container safety monitoring of ship-borne dangerous goods. Based on the actual requirement of container safety monitoring of ship dangerous goods, this paper designs a container monitoring system based on wireless sensor network technology. The system mainly includes wireless sensor network node and monitoring center data management software. Firstly, on the basis of JN5148 module, three kinds of hardware circuits of wireless sensor network nodes are designed, which are coordinator node, routing node and monitor node. In order to solve the problem that the monitoring objects of dangerous goods container are many and changing frequently, a "plug and play" sensor module is designed. The monitor node can identify and read the sensor module by multiplexing 12C bus. Secondly, on the basis of JenNet protocol, the software of coordinator node, routing node and monitoring node is designed. In addition to the normal network and communication function, the coordinator node has the functions of serial port communication, obtaining the data collected by monitoring node, etc. The routing node has the functions of saving the collected data of the monitoring node and recording the status of the child node, and the terminal node has the functions of identifying the sensor module and collecting the data. Thirdly, the data management software of dangerous goods container safety monitoring center is designed by using Visual Basic. The software has automatic configuration serial port, data receiving and automatic storage, system running state and warning information prompt, data curve, table display, etc. Network topology display, historical data query and command sending and other functions. At last, the safety monitoring system of ship dangerous goods assembly is tested by network, data acquisition and energy consumption.
