Abstract
An interventional control method based on a computer control system. An interventional control system is designed on the basis of an original computer control system; the analog-to-digital conversion unit of the interventional control system receives a signal from the data acquisition module of the original computer control system and said signal is processed by a control processing unit according to a built-in program; then a digital-to-analog conversion unit performs digital-to-analog conversion on the signal output by the control processing unit and then outputs a signal obtained after the digital-to-analog conversion to the analog-to-digital conversion unit of the original computer control system. According to the interventional computer control system, on the basis of an original computer control system, the analog-to-digital conversion unit of the interventional control system receives a signal output from the data acquisition module of the original computer control system and control processing is performed on said output signal; then the digital-to-analog conversion unit of the interventional control system outputs a signal to the analog-to-digital conversion unit of the original computer control system. The function upgrade of an original computer control system is implemented without changing the operating program of the original computer control system.
