基于 CAN 总线的船舶电网绝缘监控系统的设计

为了保证船舶、人身安全和船舶电力系统的供电可靠性，通过介绍现有船舶电网绝缘故障查找方法，分析船舶电网绝缘监控的原理，设计了一种基于 CAN 总线的自动检测查找电网绝缘故障的方法。该方法能够更加快速查找并准确显示电网故障支路绝缘状况，从而进一步提高船舶电网绝缘监控系统运行的可靠性。

Research on Insulation Monitoring for Ship Power Network based on CAN Bus

Nowadays, in order to guarantee the reliability for ship, personal safety and ship power supply system, three phase three wire insulation are adopted in modern ships.One of the key factors for ship safety is ship power network insulation monitoring.There is a broadly prospect of application for automatic search network insulation fault technology.The article analyzes the principle of ship power network insulation monitoring, design methods for searching the automatic detection according to the existing ship power network search method.By applying the ship power network insulation and CAN bus, the ship power network insulation branch troubleshooting can search the faults rapidly and show the fault accurately, therefore, the reliability increases during the operation of the system.
