Abstract

The invention provides a system for monitoring the state of a ship power monitoring network, which are used for monitoring the state of the ship power monitoring network. According to the ship power monitoring network, a multifunctional workstation and a database server are respectively connected with a switch to form an upper layer high-speed switched industrial Ethernet; the switches are connected to a lower layer controller area network (CAN) onsite bus network through an object linking and embedding (OLE) for process control (OPC) power supply gateway, an OPC distribution gateway and an unloading gateway, and the switch is connected with the RS422 network through unloading the gateway; and a maintenance support computer is connected with the switch in the power monitoring network and comprises a control module, and a network monitoring module, a switch information acquisition module, a flow curve plotting module, a data transceiving module and a database access module which are connected with the control module. By the method and the system, state information of equipment in the Ethernet and a CAN can be displayed in real time, state and alarm information of all the switches can be acquired comprehensively, the labor intensity of sailors who find network failures can be remarkably reduced, the maintenance support time can be shortened, and the ship assurance level can be improved.

Description

technical field [0001] The invention relates to the technical field of ship power monitoring systems, in particular to a state monitoring method and system for a ship power monitoring network. Background technique [0002] The power monitoring system is the core equipment of the informatization of the ship's power system. How to ensure the safe and reliable operation of the power monitoring network of the system is the key to realizing the informatization of the ship's power system. [0003] The main task of the power system monitoring system is to monitor the operating status of the entire ship's power system, to conduct real-time measurement, centralized supervision and command remote control of the four links of power generation, power distribution, power transformation and power consumption, and to carry out necessary coordination and restriction. and protection, so that it can operate stably, safely, economically and with high quality no matter under normal conditions o...
