The Implementation of Instrumentation Systems of Fire Truck Simulator Based on PLC

Abstract

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.
