Research Of The Stimulation Training System And Measuring And Controlling Network

Accompanied with the construction of new apparatus, the alteration of old apparatus and the renovation of control system, the distributed control system (DCS) gets more and more applications. Meanwhile, the scale and complexity of the facilities are increased, the effects of the traditional training methods such as teaching in classroom are unsatisfactory. Therefore, the use of the computer simulation training system for the operators can compensate the shortcoming of traditional teaching and training, and will improve the training efficiency significantly.How to utilize the human and material resources to develop the computer simulation training system more independently and more quickly with lower costs and higher efficiency is a project that we should study. In this thesis, the research and practice are done based on the DCS simulation training systems for petrochemical industry, a new development strategy based on the DELPHI development studio is proposed to develop the simulation training systems more quickly with lower costs and higher efficiency.Hardware: take out the expensive but useless operational station and special keyboards for the purpose of lower input. Software: The main feature is that one machine or more machines running mode, the teacher station, the operator station and the field station will be assigned by the configuration file. In allusion to different DCS, the development of the teacher station and the field station will be carried out by editing the database file of control configuration. Meanwhile, the development of the operator station is carried out first by editing the components in the frame and then by the configuration of components in the IDE of DELPHI. All these methods will ensure efficient development.Meanwhile, how to utilize obsolete equipment to meet new system train demand is also one research field of this paper. According to YHJ-2 simulation training system, the single chip processor network is proposed based-on the concept of plug and play in this paper. The hardware structure and software design are also presented in details which is novelty and unique. This research can enlarge the scope of data acquisition and data process of measuring and controlling network, and enhance the reliability, flexibility and security of data transmission.
