Color Flow Simulation Technology-based Monitoring System Design And Realization

The acceleration of electrization railway transportation has put forward muchhigher security reliability request in traction power supply system and equipments. Byreason of many objective causes, the power cut to overhaul electrization equipmentcannot totally avoid equipment operating accidents. In order to improve the systemsecurity reliability effectively and reduce the risk of artificial carelessness and mistake,The conception of colored-current and colored circuit diagram are introduced here.The research aims to provide the related users a convenient and intuitionistic real-timecircuit monitor and control resolvent in manner of distinguishing the voltage status ofany part of the circuit by different colors.First, colord-current and its related conceptions are introduced. With the actualoperating character of circuit, the requirement and technology of implementation ofcolored real-imitation are analyzed. On the basis, a mathematics model used tocalculate the circuit logical status is presented. But there are two problems that thecolored-current arithmetic must take into consideration. To solve these main problems,two completely different kind of colored-current arithmetic are designed, one is theneighbor diffusion based colored-current arithmetic and the other is the connectedsub-graphic based colored-current arithmetic, which are evaluated and compared witheach other. Then, according to the requirements of colored-current real-imitationmonitor and control system, an applied monitor system is designed and implemented.Also, a technique to show the colored circuit diagram is addressed. Finally, anpractical application of this technology was presented briefly. Our research work issummarized and some potential works in the future are discussed.The achievements of this research include the design and implementation of acolored-current real imitation based monitor and control system. And in the system,we focus on the design of the colored-current arithmetic, which is the kernel of thesystem.
