In this paper, taking a renovation project as an example, a training system combined of “Simulation” and “Stimulate Simulation” pattern is described. The renovated system is originally composed of a HOLLIAS MACS V6 control cabinet and several HMI workstations. The simple configuration without process equipment signals can not achieve the dynamic operation of the interface, which greatly limits the scope of the training applications. In this renovation project the RINSIM simulation platform is used to develop the process system modeling software and DCS Level 1 modeling software, which is called as the “Simulation” method. Meanwhile, a simulation DCS Level 2 is developed through the DCS HMI simulating configuration software. These two portions form a complete Simulation system. In addition, through the OPC and TCP protocol, the simulation process system modeling software and DCS Level 1 control modeling software can communicate with DCS control cabinet, which forms a Stimulating Simulation system. The two systems which can be switched to one another has a high value in use both for configuration training of I&C and maintenance staff, and also for the system process operation training of operators. This paper gives a basic description of simulation system. It also analyzes the simulation system for multiple operating modes and a variety of DCS simulating solutions, focusing on several key technical difficulties in the simulation system.

Attack And Defense

We propose an integrated design method to Network attack and defense Simulation training system. Firstly, taking the actual network attack and defense subjects as materials, establishes the system-related military scenario and models several use cases from the perspective of system resources and user needs. Then, using these use cases plans every system components (federate members) in terms of the distributed framework of HLA. More importantly, the workflow of a typical use case according to the publish/subscribe relationship among federate members is described. Associated with this use case, the structure (and behavior) model, internal/external class and program points of the system are modeled, defined and designed respectively. Finally, the expansibility of the system is described in detail. This method can accurately grasp the properties, functions, behaviors and other characteristics of system members (objects) and improve the rationality and consistency of the simulation system modeling.

The Impact

Abstract The requirement for capturing and storing Carbon Dioxide will continue to grow in the next decade and a fundamental part of this is being able to transport the fluid over large geographical distances in numerous terrains and environments. The evolving nature of the fluid supply and the storage characteristics ensure the operation of the pipeline remains a challenge throughout its operational life. This paper will examine the impact of changes in the fluid composition, storage locations, ambient conditions and the various operating modes the pipeline will see throughout the lifecycle, highlight the technical design and operational challenges and finally give guidance on future developments. The thermodynamic behaviour of CO2 with and without impurities will be demonstrated utilising the fluid characterisation software, MultiflashTM. The fluid behaviour and hydraulic performance will be calculated over the expected operational envelope of the pipeline throughout field life, highlighting the benefits and constraints of using the single component module in OLGATM whilst comparing against a compositional approach when dealing with impurities. The paper will demonstrate through two case studies of varying nature including geographical environment, storage location (aquifer vs. abandoned hydrocarbon reservoir) and ambient conditions, the following issues: The impact of the storage type on the pipeline operations and how this will evolve with time; The environmental conditions and the impact these have on selection of process equipment and operational procedures (i.e. shutdown); and The impact the CO2 composition has on the design of the CO2 pipeline, and The paper will conclude with a set of guidelines for undertaking design analysis of CO2 pipelines for variations in fluid composition, storage locations and ambient conditions as well as some key operational strategies. This paper utilises the current state of the art tools and how these evolving tools are making this technically challenging area more mainstream.

Abstract UAV-borne missile is effective weapon to attack enemy ground targets. It is expensive, costly and difficult to live-fire drill. Using virtual training instead of actual training can greatly improve the training efficiency and the combat effectiveness. The article regards the operation training of a certain type of UAV-borne missile shooting training as the research object, based on the development of a visual simulation system for UAV-borne missile, uses the object-oriented design method to design a virtual training system based on LabVIEW. The system can realize the shooting operation training of trainees in a virtual environment, and achieve the goals of reduce training costs; improve training efficiency and shorten training period.
