摘　　要：实现船舶电站自动控制的关键是通信技术,文章基于Modbus通信协议,设计了船舶电站自动控制系统通信软件,包括上位机PC和下位机PLC部分,完成对船舶电站实时监控。给出了控制系统的具体实施方案,详细讨论了通信协议的设定及通信程序的编程要点。实践证明该通信软件具有较高的可靠性。To realize the automatic controlling of ship power plants, communication technology is a key. This paper introduces an approach to realize the real time communication between PC and PLC based on Modbus protocol, designs the communication software of real-time monitoring system of ship power plants, and presents the specific executive plan of the monitoring system. It discusses the setting of the communication protocol and the key points of the communication program in detail. Practice proves that the software has higher reliability.
