[0002] Distributed control systems (DCSs) are the core of power plant unit control. Existing imported systems suffer from insufficient autonomy and high external dependence. Achieving complete DCS autonomy and control is essential for ensuring energy security. Currently, the domestic transformation of DCS systems for thermal power generators is in full swing. During this process, all actuators on the DCS side must be rewired. After wiring is complete, the wires must be individually actuated, and only after the actuation is normal can power be turned on. This is a labor-intensive and error-prone task. To address these challenges, a rapid wiring verification device was designed for the widely used AUMA actuators. Summary of the Invention

DETAILED DESCRIPTION

[0012] Reference Figures 1-4 A device for quickly verifying DCS wiring on AUMA actuators features components including a controller 1 and a prefabricated wiring panel 3. The controller receives on / off commands from the DCS and is connected to the prefabricated wiring panel 3 via a connecting cable 2 for signal transmission. Signal verification is achieved by operating the controller 1, and the prefabricated wiring panel 3 interfaces with the AUMA actuator wiring panel for signal transmission.

[0013] The controller includes an on-command indicator light, an off-command indicator light, a power switch knob, a power indicator light, an on-feedback button, an off-feedback button and a fault button. The on-command from the DCS is connected in series with the on-command indicator light, the off-command from the DCS is connected in series with the off-command indicator light, the on-feedback button is connected in series with the coil of the first relay, the off-feedback button is connected in series with the coil of the second relay, and the fault button is connected in series with the coil of the third relay.

[0014] The power switch knob is used to power on the controller. The controller has a built-in rechargeable 24V power module. When the power switch knob is rotated to the start position, the power indicator light lights up normally, indicating that the device has been powered on and can be used normally.

[0015] Send an open command from the DCS and observe whether the open command indicator light 4 of the control device lights up normally; send a close command from the DCS and observe whether the close command indicator light 5 of the control device lights up normally; if the wiring on the DCS side of the actuator is correct, the indicator lights can light up normally.

[0016] Simulate feedback signals from the device. Press the On Feedback button 7 to see if the On feedback indicator on the DCS screen is lit normally. Press the Off Feedback button 8 to see if the Off feedback indicator on the DCS screen is lit normally. Press the Fault button 9 to see if the Fault indicator on the DCS screen is lit normally.

[0017] The normally open contact of the first relay serves as a connection point between the terminals 39 and 40 of the prefabricated wiring board.

[0018] The normally open contact of the second relay serves as the connection point between the terminals 35 and 36 of the prefabricated terminal block; The normally open contact of the third relay serves as the connection point between the 14th and 16th terminals of the prefabricated wiring board.

[0019] The DCS opens the command as the connection point of terminals 2 and 11 of the prefabricated terminal board; The DCS comes to close the command as the connection point of the 3 and 11 terminals of the prefabricated wiring panel.

[0020] When checking the DCS wiring of the AUMA actuator, the prefabricated terminal block can be directly connected to the sunflower terminal block of the auma actuator, so that the wiring verification work can be carried out quickly without having to disassemble the wiring, which greatly improves work efficiency.
