The system simulation models have been established based on the subsystem mathematical models in addition, a relationship diagram of ship-motor-propeller has also been worked out. 在上述分析讨论的基础上,分别将所分析归纳出的子系统数学模型建立系统仿真模型,设计了船机桨关系框图。
Attention are mainly focused on the modular design of PLC program, flow figure of each subsystem, the assignment of the program function block, the communication principle between PLC and up-lever computer and the timing sequence diagram. 着重介绍了PLC程序的模块化设计以及各个工位的程序流程、程序功能块的划分以及与上位机通讯的基本原理和时序图;
Then analyzes some laws of the existing system can be optimized. Based on MES I build chilled water subsystem software architecture diagram and hardware architecture diagram. Finally I successfully establish the chilled water management information system. 然后分析了现有系统的可优化部分,依据MES原理搭建了冷冻水子系统的软件架构图和硬件架构图,成功的建立了冷冻水管理信息系统。
Drawing system similar RBD ( Reliability Block Diagram) module draw subsystem block diagram, describe the system redundancy strategy and draw automatically the system similar RBD in the user interface one by one. 系统近似RBD(ReliabilityBlockDiagram)绘制模块在用户界面依次绘制功能子系统框图、描述系统冗余策略、自动绘制系统近似RBD。
And then the realization of the subsystem used in the main class to make the design, with timing diagram describes the collaboration between classes, and finally describe the realization of the system and the use of key technologies. 然后对实现该系统用到的主要类做出了设计、用时序图描述了类之间的协作关系,最后描述了系统的实现和所用到的关键技术。
Other web technology includes js, dom, CSS, ajax, etc. This paper designs each subsystem with class diagram and sequence diagram in detail, system adopting J2EE layered structure. 其他网页技术包括js、dom、Css、ajax等。本文分别用类图和时序图的形式对各个子系统进行了详细设计,系统采用J2EE分层架构。
