Multi-transport protocol equipment monitoring system based on OPC UA

Abstract

The invention discloses a multi-transport protocol equipment monitoring system based on OPC UA, and the system comprises an OPC UA server which is connected with a plurality of pieces of underlying equipment; a data acquisition module, arranged in the OPC UA server, and the data acquisition module being used for acquiring first data of a plurality of pieces of bottom-layer equipment; a data conversion module, arranged in the OPC UA server, an input interface of the data conversion module being connected with an output interface of the data acquisition module, and the data conversion module converting the first data into second data in a preset format; a Web server, connected with the OPC UA server and used for processing and storing the second data; and an OPC UA client, respectively connected with the OPC UA server and the Web server through a network. A system which is originally of a C/S architecture is reconstructed into a B/S architecture, monitoring of the data at a PC end or a mobile end is achieved, the problem that traditional ship data monitoring can only be conducted at the PC end is solved, and a user can have access to the data at a mobile terminal conveniently.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an OPC UA-based multi-transport protocol device monitoring system. Background technique [0002] The emergence of OPC UA solves the problem of multiple protocol conversions. OPC UA is developed on the basis of OPC. Before the emergence of OPC, the main problem faced by automation software development was to access automation equipment through a large number of different bus systems, protocols, and interfaces, which made software development extremely cumbersome. To solve this problem, a non-profit organization, the OPC Foundation, defined a unified specification. Once this specification was released, it was generally accepted by people. However, the early OPC specification was too dependent on Windows, and most embedded devices are currently based on Linux, so the emergence of OPC UA perfectly solves this problem, and the configuration is simpler than OPC. [0003] Nowa...
