Marine engine room data acquisition and monitoring system based on OLE for process control (OPC) technology

Abstract

The invention discloses a marine engine room data acquisition and monitoring system based on an OLE for process control (OPC) technology. The system comprises: an OPC engine room monitoring system, an OPC engine room data access server, a serial port module, a CAN module, a digital quantity acquisition card module and an analog quantity acquisition card module. The OPC engine room monitoring system and the OPC engine room data access server use an OPC port technology standard to carry out mutual communication. The digital quantity acquisition card module and the analog quantity acquisition card module are intelligent acquisition cards. The OPC engine room monitoring system follows the technical standard of the OPC standard. The digital quantity acquisition card module used in the invention sets a working module and an address through a 8 bit dial switch so that acquisition point resources of an acquisition card can be used maximumly. According to the invention, because the technical standard of the OPC standard is used to design and develop a marine engine room state monitoring software system, a communication driving program of hardware equipment in the software system can not be developed repeatedly.

Description

technical field [0001] The invention relates to a ship engine room data collection and monitoring system based on OPC (OLE for Process Control) technology. Background technique [0002] The ship engine room data acquisition and monitoring system is responsible for collecting and processing the operating status data of many equipment in the engine room in the ship system, and displays the operating status of the equipment in a more intuitive way for the relevant personnel of the ship to check in real time and grasp the working status of the engine room in a timely manner. At present, there are many implementation forms of the underlying data acquisition card as the basis of the ship engine room data acquisition and monitoring system, such as PLC, DCS, RS-485 bus and various field buses. And because the data acquisition cards provided by different companies are generally developed and designed for the entire ship market, there is usually a big gap between their communication m...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the present situation of ship engine room data acquisition and monitoring system, the present invention will propose a ship engine room data acquisition and monitoring system based on OPC technology to solve the problem of idle waste of resources at the collection point of the state data acquisition card; solve the problem of hardware equipment in the software system The problem of repeated development of the communication driver; solve the problem that if the bottom data acquisition card of the ship’s engine room changes during the upgrade and transformation of the ship’s engine room, the change of the communication interface of the acquisition card may lead to the collapse of the entire upper ship’s engine room monitoring software system
