【摘要】：由于運輸周期長、環(huán)境惡劣,船載危險品集裝箱極易發(fā)生事故,而且集裝箱的封閉性及船上人員、設備的缺乏給事故的發(fā)現和處理帶來了極大的困難,因此對船載危險品集裝箱進行安全監(jiān)測就顯得尤為重要。目前,應用于公路、鐵路運輸領域的集裝箱監(jiān)測系統(tǒng)一般采用RFID、GPRS、GPS及GIS等技術,但這種系統(tǒng)的通訊方式、監(jiān)測對象及監(jiān)測系統(tǒng)結構并不適用于船載集裝箱運輸。近年來無線傳感器網絡技術發(fā)展迅速,并成為了船舶自動化的一個發(fā)展方向。自組織、低功耗、低成本等特點使無線傳感器網絡技術成為船載危險品集裝箱安全監(jiān)測較好的選擇。 本文從船載危險品集裝箱安全監(jiān)測的實際需求出發(fā),設計了一種基于無線傳感器網絡技術的船載危險品集裝箱監(jiān)測系統(tǒng),該系統(tǒng)主要包括無線傳感器網絡節(jié)點及監(jiān)測中心數據管理軟件。 首先,在JN5148模塊的基礎上,設計了三種無線傳感器網絡節(jié)點的硬件電路,分別為協調者節(jié)點、路由節(jié)點和監(jiān)測節(jié)點。同時,為解決危險品集裝箱監(jiān)測對象多且經常更換的問題,設計了“即插即用”的傳感器模塊,監(jiān)測節(jié)點通過復用12C總線來識別和讀取傳感器模塊。 其次,在JenNet協議的基礎上,設計了協調者節(jié)點、路由節(jié)點及監(jiān)測節(jié)點的軟件。除正常的組建網絡及通信功能外,協調者節(jié)點具有串口通信、獲取監(jiān)測節(jié)點采集的數據等功能,路由節(jié)點具有保存監(jiān)測節(jié)點采集數據、記錄子節(jié)點狀態(tài)等功能,終端節(jié)點具有識別傳感器模塊及采集數據等功能。 再次,利用Visual Basic設計了危險品集裝箱安全監(jiān)測中心數據管理軟件,該軟件具有自動配置串口,數據接收及自動存儲,系統(tǒng)運行狀態(tài)及預警信息提示,數據曲線、表格顯示,網絡拓撲顯示,歷史數據查詢及指令發(fā)送等功能。 最后,對本文所設計的船載危險品集裝安全監(jiān)測系統(tǒng)進行了組網測試、數據采集測試及能量消耗測試。
[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.
