| Abstract: | Implementing the processing of data acquisition system,such as real-time alarming and printing,by industrial computer,is the subject universally studied in gather & scater system. Approciately processing the residence of interrupt is the important problem of it.By interceptint the real-time timer interrupt processing of data acquisition signal,approciately distributing internal storage, adequately making use of the port of industrial computer and printer, and controlling signal and phase,solved the problem of the residence of interupt in concentration and dispersion control. |
