The vacuum experimental system of mpt has been designed , manufactured , mounted , and debugged , which is made up of vacuum subsystem , measurement and control subsystem of virtual instrument , subsystem of small thrust measurement , subsystem of propellant storage and supplying , and prototypes of mpt 完成了mpt真空实验系统的设计、加工、安装和调试。系统包括真空子系统、虚拟仪器测控子系统、小推力测量子系统、推进剂贮存供应子系统和mpt实验样机。
In this paper , the study was based on the emulational experience system of the tractor - implement . the emulational control system was composed of three parts : master pc monitor system , transmission and throttle control subsystem , engine load simulated control subsystem . using the system , many studies and experiments could be carried out on the implement units 本文的研究是在拖拉机作业机组仿真试验系统平台上进行,仿真系统的控制系统由上位机监控系统、发动机及换挡控制系统、发动机负荷模拟加载控制系统等三大部分组成,利用本控制系统能对机组进行各种加载试验研究。
The mws constitutes of missile subsystem , floor support subsystem , and energy control subsystem . through analyzing the system structure and modeling the system , we got the maintainability diagram and mttr ( mean time to repair ) model of the three subsystems , and using bdd method and makov method to solve common - cause - failure problems . for verification of maintainability , we have four sutra methods on the presupposition of not known the distributing , known the distributing , known the distributing and the variance 分析导弹武器系统结构的基础上,通过对导弹武器系统进行维修性建模和分析,给出了导弹武器系统的导弹弹体系统、地面支援系统和火控系统三个分系统的维修性框图和平均修复时间模型,并研究了维修性模型中运用bdd方法和马尔可夫方法解决共因故障的问题。
Labview 、 visa ( virtual instrument software architecture ) and rtsitechnique are used to integrated the plc control subsystem 、 servo controlsubsystem and machine vision detecting subsystem ; design the main controlprogram and user interface of the integrated control system ; conclude amultitasking attemper strategy of this integrated control system . in order torealize the automation machining function of the notched impact specimen , debug this integrated control system in the production line . the function result of 利用虚拟仪器的软件开发环境labview 、 visa ( virtualinstrumentsoftwarearchitecture )函数库以及rtsi技术把plc控制子系统、伺服控制子系统、视觉检测系统有机地集成为一体,并设计集成控制系统总程序以及人机交互界面,总结出一套适用于本系统的软件多任务调度策略。
