The invention belongs to the technical field of driving control, and provides a digital control system, a driving device and a driving circuit thereof. In the present invention, by adopting a drive circuit comprising an open instruction memory module, an operating mode processing module, a power failure processing module, a device protection module, a backup device startup control module, a control signal processing module and a fault management module, the drive circuit The various modules of the system work together to finally complete the start-stop control of the drive equipment, and in the process of start-stop control of the drive equipment, standardize the design of various functional protection logics without relying on the designer's experience and skills, and the degree of intelligence High, and can carry out fault alarm, which solves the problems of poor design standardization and low intelligence in the existing digital control system of nuclear power plants.
Description
technical field [0001] The invention belongs to the technical field of driving control, and in particular relates to a digital control system, a driving device and a driving circuit thereof. Background technique [0002] As the main control system of domestic nuclear power plants, the digital control system of domestic nuclear power plants is equipped with a variety of driving equipment, such as motors, and as the main driving source in the digital control system of nuclear power plants, the control of driving equipment is in the operation control of nuclear power plants appears to be particularly important. At present, when the existing nuclear power plant digital control system is designing the control function logic of the drive equipment, it usually only expresses the operation control function requirements of the equipment with basic modules such as AND gates, OR gates, and NOT gates. [0003] However, although the existing digital control system of nuclear power plant...
