The implementation of instrumentation systems of Fire truck simulator Based On PLC

摘要

The structures of the instrumentation systems of the airport fire truck simulator uses a distributed control of the PC and PLC,combined with the advanced technology of the widespread use of the stepper motor control of the instrument.And combined stability,adaptability and strong anti-jamming capability of PLC and the stepper motor's positioning accuracy,ease of control,and high reliability.It is used the unique high-speed pulse output function of PLC to realize the real time and accurate control of stepper motor.It is also use the serial port class SerialPort in VC + + 6.0 programming environment on Serial communication side.The experiment proved that the system design is reasonable,and the instrument can be a smooth,quiet and accurate operation.
