【摘要】 目前我国对地铁转向架性能测试系统研究较少，大都靠国外引进，价格昂贵，因此自行研制一套转向架综合测控系统是十分必要的。本文基于测控系统的功能要求，对各参数测量通道的组建，PLC控制系统的设计，模拟量加载控制的模糊算法实现，上位机实时监控程序等四个方面进行了设计和探讨。首先对转向架性能影响较大的四轮称重参数进行分析，设计了精度较高的称重测力变送器电路。采用可编程控制器与工控机作为系统的核心，解决了上位机与操作台对转向架定位控制的切换，同时实现了操作台对转向架进行手动加载的功能。 分析转向架加载控制系统的模型，得到其传递函数，在增量式数字PID控制算法的基础上，结合模糊控制理论，利用Matlab语言，设计了模糊自整定PID控制算法，并编制了参数K_p的模糊矩阵查询表。利用Matlab中的Simulink和Fuzzy工具箱进行仿真研究，仿真结果表明算法是可行的。最后利用组态王6.02设计了实时监控软件，为进行转向架加载试验的提供了良好的人机交互界面，避免许多人工重复性劳动。更多还原

【Abstract】 At present time, the test system for metro bogie is rarely researched in our country. It is basically imported from other countries and it’s cost is too high. Accordingly, it is very necessary to design independently a metro bogie test system which measures performance of metro bogie. In this paper, based on the function demand of the measure and control system, the four parts of the system are designed and researched which includes establishing measure channels for every parameters, designing PLC control system, implementing fuzzy control arithmetic for analogue quantity load and real-time monitor -control program. Firstly, the force metro bogie four wheels weighted are analysed, because it have a big impact on metro bogie performance, and the weight transducer circuit is designed. The program controller and industrial computer are used as the core of the system. The switch of computer and operating panel is solved to locate metro bogie respectively, and the operation of the manual load for metro bogie is realized.The model of the metro bogie loading control is analysed and the system transfer function is acquired. Based on digital PID control arithmetic and combined with fuzzy control theory, the arithmetic of fuzzy self-regulation PID control is implemented. The search table of fuzzy matrix is worked out, which regulates the gain KP of PID controller. Simulink and Fuzzy toolbox is applied to simulate the arithmetic in Matlab and the result of simulation indicates the arithmetic is feasible. The real-time monitor and control software is developed by configuration software Kingview 6.02, and good interactive interface is provided to avoid the heavy manual work.更多还原
