The requirement of real time is very high, all control tasks ;ire classified into relatively independent subprogramme by executive frequency and function to time-sharing execute.
A new multiqueue method with variable priority is presented to solve the real time dynamic scheduling problem of automatic transportation system in flexible electrophoresis production line.
In order to adapt to real time simulation, the nodes of system and the predigestion was made according to the characteristic of reactor coolant system which will be simulated.
Buzzer will start working if there exists barriers less than 1.5m distance with back of car, the hurrier of voice, the closer of distance, the distance could be displayed on real time as well.
