Abstract

The present invention discloses a nuclear safety classification digital control system (DCS) maintenance method comprising partition according to nuclear safety classification digital control system (DCS) control cabinet function; connection of a single nuclear safety classification DCS control cabinet in each partition and a partition photoelectric conversion hub by a cabinet photoelectric conversion hub; maintenance of the nuclear safety classification DCS control cabinet in each partition by use of a nuclear safety classification DCS maintenance device by the partition photoelectric conversion hub. The maintenance technology providing secure and convenient maintenance for a nuclear power unit can be achieved. Furthermore, the present invention also discloses the nuclear safety classification DCS maintenance device and a nuclear safety classification DCS.

Description

technical field [0001] The invention belongs to the technical field of nuclear power, and in particular relates to a maintenance method, device and system for a nuclear-level DCS. Background technique [0002] The nuclear safety-level digital control system (Digital Control System, DCS) of a nuclear power plant, referred to as "nuclear-level DCS", includes nearly a hundred control cabinets. During the reactor type debugging and operation of nuclear power plants, it is necessary to use maintenance tools and computers to diagnose faults, adjust parameters or download software for nuclear-level DCS control cabinets. At present, the maintenance tool computer is generally used to connect the CPU of the control cabinet 1 to 1 to modify the control cabinet accordingly. Due to the large number of cabinets, the relevant modification work has brought a lot of inconvenience to the on-site commissioning and maintenance personnel. Once the nuclear power unit is overhauled, when the rea...
