[0002] With the increasing use of digital control systems (DCS) in nuclear power plants and their increasing digitalization, DCS commissioning and process system logic control channel testing (TP09) require a large number of simulated test signals to be loaded onto the DCS inputs. This requires significant manpower, material resources, and man-hours to simulate signals from other upstream systems. These signals include DI, AI, RTD, and pulse signals. During testing, human error can easily lead to test errors, reducing test efficiency and delaying commissioning. Furthermore, some output signals processed by the DCS logic cannot be displayed on the DCS screen, making these signals indiscernible. Currently, some power plants use similar experimental setups for testing. While the structural principles are similar, the hardware composition and network configuration differ slightly, primarily in whether a dual-loop network is used and in the quantity and distribution of hardware.

However, the above-mentioned simulation detection device that can improve the debugging efficiency of a digital control system requires multiple connections of cables and network cables during simulation detection, which is not conducive to improving the efficiency of simulation detection. Therefore, it is necessary to improve it in view of the above-mentioned problems. Utility Model Content
