Design and implementation of an expert system for remote fault diagnosis in ship lift

In this paper an expert system for remote fault diagnosis in the ship lift was developed by analysis of the fault tree and combination with VPN. The fault tree was constructed based on the operation condition of the ship lift. The diagnosis model was constructed by hierarchical classification of the fault tree structu~, and the inference mechanism was given. Logical structure of the fault diagnosis in the ship lift was proposed. The implementation of the expert system for remote fault diagnosis in the ship lift was discussed, and the expert system developed was realized on the VPN virtual network. The system was applied to the Gaobaozhou ship lift project, and it ran successfully.     

景洪水力式升船机承船厢充放水运行流程设计

水力式升船机是高坝通航建筑物,其电气控制系统的正确和快速反应极为重要。以景洪水力式升船机的驱动系统和承船厢系统为例,采用充、泄水阀门和承船厢的上、下游卧倒门的自动化控制流程,通过升降承船厢实现厢内自动快速充放水,此方法已在景洪升船机取得成功应用。
