| Abstract: | A control system consisting of PLC and upper computer is adopted in the new hydrogen generation system. In detail, CRT and keyboard are the main methods of monitoring and control, and they carry out the centralized control for the whole technologic system by PLG. The whole control system has a perfect function of interlock alarming, data acquisition, CRT screen display, parameter processing, level limit alarming and table printing etc. The structure, control function and the treatments for common faults in routine maintenance are introduced in brief. |
