The thesis mainly discussed the Human-machine Interaction technology of distributed control system and the character of real-time database technology eXtremeDB. The thesis focuses on the Human-machine Interaction in the supervisory layer, it improves the software interface for targets at user demands based on human engineering theory. Using eXtremeDB as the platform of data supervising and exchanging, period of software developing will be decreased and the procedure will be simplified. Good performances show that security and stability are improved when it apply to actual power plant. |
