Closed-loop test platform used for instrument and control system of nuclear reactor and driven by real-time simulation data

The invention discloses a closed-loop test platform used for an instrument and control system of a nuclear reactor and driven by real-time simulation data The platform comprises a nuclear reactor real-time simulation platform and a signal transmission array. Before test, a configuration data in the signal transmission array downloads variable data and attribute information to a data processing module; the data processing module refreshes variable values which represent onsite sensor signals of the reactor according to real-time simulation data provided by the reactor real-time simulation platform, and addresses corresponding sub channels in an IO module according to related address information; the IO module converts the real-time simulation data into electric signals, transmits the electric signals to the instrument and control system, and converts real-time control signals emitted by the tested instrument and control system into real-time control data; and the real-time control data is back fed to the nuclear reactor real-time simulation platform via the signal transmission array to realize closed-loop test. The closed-loop test platform can greatly improve the test credibility and the test efficiency.
