| Abstract: | Distributed control system based on serial input output(SIO)bus is designed in double aero-thermodynamics test-unit.RS422 protocol are used for the communication and control among management station and field control station.An independent high accuracy data acquisition system is also designed in management station to correct and coordinate the field station by using the high speed IEEE-488 GPIB bus.Distributed control of temperature,pressure and flow is realized in the test-unit. |
