摘　　要：为提高船舶电力推进的控制质量与安全可靠性,设计了基于施耐德M340 PLC和XBTGT7340触摸屏的电力推进系统监控装置。装置的硬件方面,以Modbus现场总线技术为基础,运用ATV61变频器实施推进电机控制,运用PM850和ION7650两种电力参数检测仪表实施推进系统监视。装置的软件方面,在完成现场总线通讯、推进系统故障报警编程的基础上,鉴于船舶航行海况等因素对于推进系统安全运行的巨大影响,设计了转速/转矩联合的控制方式和两种控制方式进行无扰动切换的逻辑功能。装置制作完成后进行的推进电机控制实验表明,其功能可以满足船舶电力推进监控的主要要求。In order to promote the control quality and safe reliability of shipboard electrical propulsion, a monitoring and controlling device of electrical propulsion system based on M340 PLC and XBTGT7340 touch screen is designed. In terms of hardware, the ATV61 convertor is used to control the propulsion motor and two power meters, PM850 and ION7650, are used to monitor the propulsion system based on the Modbus field bus technology. In terms of software, after the programs of field bus communication and propulsion system fault alarms are finished, a speed/torque joint control method and a logical bumpless switching function for two control methods are designed considering the great impact of sea conditions on the safe running of propulsion system. Propulsion motor controlling experiment shows that the device meets the main demands for the monitoring and controlling of shipboard electrical propulsion.
