基于Java SE1.4的道桥及车辆施工信息管理软件

Management Software of Road-Bridges and Vehicles' Information in Building Based on JAVA SE1.4

为实现道桥施工中信息的传输与管理,需要提取施工过程中的道桥和车辆信息。通过对对象实体的分析,可将道桥的全部信息封装在一个地图中,车辆可作为移动单元。利用统一模型语言(UML:Unified Modeling Language)对道桥单元和移动单元模型的属性进行描述,由此建立道桥施工中道桥及车辆的信息模型。在该软件中,文件的存储采用Unicode(统一码)字符集的字符编码格式和Java SE(Standard Edition)的对象存储方式进行;利用Java中的ServerSocket和Socket两个类提供的功能完成信息传输控制;利用图形用户界面(GUI:Graphics User Interface)方法实现地图编辑器。该软件可计算移动单元间真实距离,在一定容错范围内车辆显示不会偏离道路,在一定程度上对操作系统的网络连接功能依赖小,具有较强的适应性。由于采用Ja-va编程软件,因此具有较强的跨平台能力。

In order to realize information transmission and management, information of road-bridges and vehicles during road-bridge constructing needs to be collected. Analyzing the objects, the vehicles are being as moving cells, and the information of road-bridges can be embedded in a map. Using UML （Unified Modeling Language ） properties of road-bridges and vehicles are described, and the information models of road-bridges and vehicles are built. In this software, the character coding of Unicode character set and object storage form in Java SE （Standard Edition） are used in saving files, information transfer control use the function provided by two classes--ServerSocket and Socket in Java, and the map editor is designed by using GUI （Graphical User Interface）. The real distance between two vehicles can be calculated in the software, and the vehicles cannot be displayed aberrance within allowed error tolerance range, and to a certain extant, the software is provided with high adaptability due to less depending on the function of network connections of operation system. Programmed by Java, the software can be used on different platform easily.
