PLC is combined with the QNX real-time system to meet the real-time remote control requirements of the new HT-7DNB(diagnostics neutral beam)power supply control system.Star-shaped local area networks which consist of on-site bus control layer
PLC and QNX6.3.2 real-time control monitor layer and the monitor layer of Windows to connect upper and lower and realized the requirements of powers supply control system between different operating platform.From the selecting of hardware platform
software programdesign
network design and analysis
etc.to complete the design and implementation of DNB power real-time control system.Experiments show that the set of power have good real-time property
its performance is stable and reliable and the timing of pulse error is less than 1ms
