PID Control Data Base creation device of DCU is safety operation technology of train door. For keeping the normal condition of door, measured value of regular condition and unusual(trouble detected) condition should be recorded by encoding. The door should be measured itself as this value is compared with standard vale. If it's condition of the door and for reaching the datum point and ot does self-diagnosis. This aim for Technical Realization is that carry out safety train operation by using the Estimation Data Base and protect before door-trouble.
