Design of Fault Diagnosis and Condition Assessment for the Information and Control System of Ship

The main function of the Information and Control System depends on the software system. It is different from the pure hardware system, like a mechanical system. These characteristics make it difficult to meet the needs of users for fault diagnosis, maintenance, and repair, such as lacking fault diagnosis, highly specialized diagnosis technology, operate difficultly,. Based on the Integrated Platform Management System (IPMS) of ship as the research object, the author puts forward a comprehensive evaluation method with the general performance parameters and characteristic function parameters. The comprehensive evaluation method uses a variety of monitoring rules to realize the monitoring of system state and fault diagnosis, and supports the combination of automatic monitoring data and user-imported data to realize the real-time and global condition assessment of IPMS. It could help the users who are engaged in the maintenance to locate system faults and get system condition. As the result, the decision-making ability of users is improved.
