To keep the 2MW equipment for producing acetylene by coal H-plasma pyrolysis running stably and safely

and to improve acetylene yield

an multi-function control system has been designed and implemented. In this system

the time slice division method has been adopted to collect important signals at high speed and in continuous mode for a long time. For improving the stability and the response speed of the control system

Integral Separation Control Arithmetic has been used. Moreover

to meet local user and remote user requirements

the control system has provided fast and visual information by the combination of C/S mode and B/S mode. The control system has shown favorable stability

reliability and usability in many experiments.
