4. Working Principle
After power-on, the ALSTOM SDK-C0167-1 module automatically executes full-board hardware initialization and comprehensive self-test procedures, sequentially verifying the integrity and stability of power supply circuits, signal acquisition channels, output driving units, onboard circuits and bus communication links. After confirming no abnormalities, it completes system configuration matching and enters normal standby operating mode.
During regular system operation, the module serves as a core hub for field signal acquisition & conditioning, logical operation processing, remote command execution and bidirectional data interaction.
On the uplink, it continuously collects real-time switching status and operation feedback signals from field auxiliary equipment, solenoid valves, contactors and interlock switches. After built-in filtering, waveform shaping and anti-interference verification, raw signals are converted into standardized digital signals and uploaded to the upper master control system to provide accurate data support for unit logical computation, condition judgment and status monitoring.
On the downlink, it receives real-time control commands issued by the master control system for equipment startup/shutdown, working condition regulation, interlock switching and loop conversion. The internal integrated chip rapidly parses and computes commands to drive output units to deliver precise command signals and actuate field actuators to execute corresponding actions, realizing fully automatic linkage control between the master control system and field equipment.
The module continuously monitors operating conditions of all signal channels, output loops, power supply and bus communication throughout operation. Once signal distortion, channel abnormality, load fault, power supply out-of-tolerance, communication loss or other hidden hazards are detected, it immediately triggers self-protection mechanisms to lock faulty channels and isolate abnormal signals. Fault codes and event logs are recorded synchronously and alarms are uploaded to the master control system to pinpoint faulty channels. It effectively prevents fault propagation leading to false logical action, accidental equipment startup/shutdown, unit working condition fluctuation and system operation disorder, delivering all-round guarantee for accurate signal transmission, stable logical operation and reliable equipment linkage of turbine control systems and power protection systems.
