Based on basic theory and methods of fault injection, the software-based fault injection was constructed for distributed and inter-operated simulation architecture based on High Level Architecture (HLA). The fault test program of communication in train control simulation system was designed. The fault injection tools were used to control train control model. Every module in train control model should...
High-speed train control system is one complex security system with lots of functions, which means that it is necessary to build up high-speed train control system simulation & testing integration platform to start function and system verification and validation (V&V). In this paper, key techniques of high-speed train control system simulation & testing integration platform are studied;...
As we all know, freeway solves the problem about the lack of the transportation resources in home and then contributes to the development in economy. However, as economy developed fast, the growing number of motor, together with people's favor to choose freeway, makes freeway full of motor, chaos and congestion. On-ramp control is one of the efficient ways to regulate the flow of traffic entering...
High-speed railway train control system is one complex security system with lots of functions, which means that deep research on safety and reliability of high-speed railway train control system be carried out. According to characters of simulation of high-speed railway train control system and advantages of fault injection, method of control system reliability and safety based on fault injection...
Because of complexity of CTCS-3 train control system, interworking testing and function evaluation could not be operated directly on the system, which means that deep research on modeling and simulation of train operation control system should be carried out. This paper proposes a modeling and verification method based on UML and colored Petri net. On the basis of analysis of advantages and disadvantages...
Research of variational curve model in limited restriction condition and application in rail train control track database was studied in this paper, raised the method, model and algorithm for digital track map auto-generation from GPS track data, through lots of testify, comparison and improvement using practical data between those algorithm and method, aim at track data, construct mathematical model...
Train operation control system is one complex system with some feature like real-time and distributing, aim at different application purpose and operation process of system lifecycle, the emphasize point and level of detail is different. In this paper, MRM-based simulation support technology and its application was studied, the modeling theory and method was studied systematically; the aggregation-disaggregation...
