Functional Description

DS200TCQBF1BAA is a Software PROM Set developed by GE. It is part of the Mark V series. It functions as a Software Programmable Read-Only Memory (PROM) Set, containing essential software programs and configurations tailored for the specific needs of the Mark V system. These programs are meticulously developed to ensure optimal performance, reliability, and compatibility with the hardware components and operational environment of the Mark V series.

Software Voting

• SIFT and Hardware Voting: The system employs a combination of SIFT and hardware voting mechanisms to enhance fault tolerance. SIFT involves redundant software running on separate controllers, while hardware voting utilizes redundant hardware components. This dual approach maximizes system reliability by cross-verifying outputs from different sources.
• Data Exchange and Calculation: At the start of each computing time frame, individual controllers within the system autonomously read sensor data. Subsequently, they exchange this data with the other controllers. Each controller then calculates the median values of the analog inputs received from all controllers. This approach ensures consistency and accuracy in data processing across the system.
• Median Calculation: After receiving sensor data from all controllers, each controller independently calculates the median value for each analog input. The median value, which represents the middle value in a sorted list of data points, is less susceptible to outliers or erroneous readings compared to mean or mode calculations. Thus, using the median enhances the robustness of the control parameter determination process.
• Resultant Control Parameter: The calculated median values serve as the resultant control parameters for each controller. By basing control decisions on the median values, the system can mitigate the impact of faulty sensor readings or transient errors, thereby ensuring stable and reliable control performance.
• Diagnostic Algorithm: The system includes a diagnostic algorithm that continuously monitors predefined deadbands for all analog inputs to each controller. Deadbands define acceptable ranges within which sensor readings are considered normal. If any analog input deviates from its deadband, indicating a potential fault or abnormality, the diagnostic algorithm triggers a diagnostic alarm. This alarm alerts maintenance personnel, enabling timely intervention to address the issue before it escalates.
