港口机械电气系统的可靠性设计

Reliability design of port mechanical electrical system

当前港口机械电气控制系统的运行仍以继电器为主,这种电气控制系统的结构非常复杂且整体运行效率较低,在实际的使用过程中不仅会消耗大量能源,而且还容易引发各种故障,无法满足港口区域装卸作业的基本需求。基于此,本文利用PLC控制系统来代替传统的继电器,以期提高港口机械电气控制系统的稳定性。

The current operation of port mechanical and electrical control system is still mainly relay. The structure of electrical control system is very complicated and whole operation efficiency is low. In actual use, it will not only consume a lot of energy, but also easily lead to various failures, which can not meet the basic needs of port area loading and unloading operations. Based on this, this paper uses PLC control system to replace traditional relays, so as lo improve port mechanical and electrical control system stability.
