  • Interventional control method based on computer control system and interventional computer control system
    Patent number: 11774928
    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.
