We have investigated domestic and foreign researches in computer simulation of relay control systems deeply ; and found there are two issues which haven ’ t been resolved perfectly : extracting electrical contact informations and simulating events ’ sequential - quality . we focused on these two issues and providing a better solution , the results are as follows : 1 . we model electrical contacts as a switched network 本文在对国内外继电控制系统计算机仿真成果进行深入研究和分析的基础上,针对继电控制系统电气联系信息提取和事件时序模拟不够完善的问题开展研究,给出了较好的解决方案,取得的成果如下: 1 .针对继电控制系统包含大量开关元件的特点,将其电气联系抽象为开关网络。
This thesis gives a distributed simulation software environment and applications for planar mechanical system based on corba ( common object request broker architecture ) using distributed object - oriented software techniques , computer network techniques , database techniques , multibody system dynamic analysis and design optimization techniques 本文针对平面机械系统，采用分布式对象技术、计算机网络技术、多体系统分析、仿真与优化技术、数据库技术等建立了基于corba的机械系统计算机辅助动力学分析、仿真与优化设计的分布式软件环境。
Electricity power system computer simulation the computing include the current computing , simple fault computing , complicated fault computing , quiescent stabilization the computing and development stabilization the computing etc . because the computing software of electricity power system are all the earlier words software , it is very difficulty for studying and isn " t easily for using and ca n ' t draw the graphics of the electricity power system ect 对电力系统的运行状态进行分析需要进行大量的计算，电力系统计算机模拟计算主要包括潮流计算、简单故障计算、复杂故障计算、静态稳定计算和动态稳定计算等计算。本文针对当前电力系统计算软件大多都是早期的字符界面的软件，学习难度大，不易使用，以及不具备电力系统图形绘制等弊病，对microsoft公司的visualc + + 6 . 0及其所提供的microsoft基础类库( mfc )展开了理论与应用的研究工作。
Based on the characteristics of fire in high - rise buildings , the papers introduces the work principle of scatter photoelectric style fire explorer , discusses the work courses of automatic alarm , and analyzed that the sense smoke explorer system with prolonged work procedure is much more reliable than that without prolonged work procedure in the fire automatic alarm . whats more the computer program graph for auto - alarm system is also worked out . 4figs . ， 5refs 依据高层建筑火灾性质和特点，介绍了高层建筑中用散射光式光电感烟检测器检测火灾的工作原理，讨论了自动控制报警的工作过程.分析比较了设有延时工作过程的感烟探测系统比没有延时工作过程的系统,火灾报警的可靠性大大增强.并编制了自动报警系统计算机程序框图,本文讨论的高层建筑中火灾的探测与自控研究，对于不同建筑结构和不同要求的火灾控制报警系统具有参考价值和社会经济意义.图5 .参5
