摘要
用工控机实现数采系统的实时报警和打印等处理，是目前集散控制系统普遍研究的课题，合理处理上位机的中断驻留是尚待解决的问题。通过截取时钟中断对数采信号进行实时处理，并对内存进行合理分配，充分利用工控机和打印机的接口，进行信号和状态的控制，解决了集散控制中的中断驻留问题。
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.
