日韩高速铁路客运站建设特点及其借鉴

日本和韩国高速铁路客运站建设及其周边发展情况对我国高速铁路客运站建设及周边地区开发具有一定启示。从日韩的经验看,客运站一般位于城市中心区,是一座高度复合的综合性建筑体,建筑设计以功能优先为原则,其周边的土地利用通常采取高强度紧凑的开发模式,同时应注意在周边土地利用上预留一定的弹性,以适应未来新项目发展的需要。

Advanced Control System Development on the Basis of Festo Training Laboratory ＂Compact Workstation＂

This article describes the development of automatic control system on the basis of Festo ＂Compact Workstation＂ training stand. Such control systems are used in different branches of industry and infrastructure including oil industry, chemical industry, water treatment, canalization and others. The stand allows realizing level, flow, pressure and temperature control systems, using pump, valves, discrete and analog sensors. Level control system is described in this work. PID （proportional integral derivative） controllers are used in these systems. Control is switched on and off and the parameters of control systems are changed by means of SCADA （supervisory control and data acquisition） system. During real technological processes, these actions are performed by the operator. The algorithm of the control system is realized using PLC （programmable logic controller）. At the end of the article conclusions about the research are drawn.
