基于NetDDE和数据库的综合船舶信息显示系统

应用ＶｉｓｕａｌＢａｓｉｃ的网络动态数据交换（ＮｅｔＤＤＥ）、ＡｃｔｉｖｅＸ数据对象（ＡＤＯ）和ＡｃｉｔｖｅＸ控件技术实现综合船舶信息显示系统。电子海图信息显示系统（ＥＣＤＩＳ），各种航海传感器和船舶自动舵的数据通信接口板送到网络服务器的大型数据库中，机舱数据采集系统因其报警显示要求的快速实时性面采用ＮｅｔＤＤＥ技术传到综合船舶信息显示系统中。整个系统中的数据处理、显示等采用ＡＤＯ和相应的控件配合

Marine Integrated Information Display System Based on NetDDE and Data Base

A marine integrated information display system is implemented by use of the NetDDE, ADO and ActiveX control technique of Visual Basic. Data of ECDIS and the information from navigation transducers and an autopilot are sent into a large scale data base in a network server through interface boards. Data of engine data collecting system are directly transmitted to the integrated information display system using NetDDE technique because of its rapid requirement in alarming display. The data process and display of the whole system are carried out by use of the ADO cooperated with corresponding control. ActiveX controls are made to simulate actual instruments for displaying all kinds of information, which reduces the work load of programming. The display of information is visual, reliable and easy to use, according to the demands of actual application of ships.
