dcs ad hoc network monitoring system based on opc standard

Abstract

The invention provides a DCS (distributed control system) self-networking monitoring system based on OPC (OLE (object linking and embedding) for process control) standards. The DCS self-networking monitoring system at least comprises a plurality of equipment or systems supporting the OPC standards, a plurality of equipment or systems supporting non-OPC standards, a switch and at least one DCS monitoring integral machine supporting the OPC standard, wherein the switch is in communication connection with the equipment or the systems supporting the OPC standards, and the equipment or the systems supporting the non-OPC standards, and the DSC monitoring integral machine is in communication connection with the switch, and is used for accessing the data of the OPC standards of the equipment or the systems supporting the OPC standards through the OPC standards, or accessing the data of the non-OPC standards of the equipment or the systems supporting the non-OPC standards through a manufacturer private protocol. The DCS self-networking monitoring system has the advantages that the monitoring data of various protocols and standards are unified into the OPC standard data input and output capability, and the strong system extension, compatibility, networking and cooperative working capabilities, so the monitoring management is simple and flexible, and the cost is lower.

Description

Technical field [0001] The present invention relates to the field of data collection and monitoring, in particular to a DCS self-organizing network monitoring system based on OPC standards. Background technique [0002] The full name of OPC is Object Linking and Embedding (OLE) for Process Control. It is a widely used industry standard for the real-time automatic exchange of data between systems. DCS (Distributed Control System), also known as distributed control system, is often used in the field of data acquisition and monitoring. The DCS system has been widely used in the field of monitoring, but due to the low openness of the DCS systems of various manufacturers, the compatibility with other manufacturers' equipment or systems is limited. [0003] In the existing DCS system, there are many types of on-site sensors and equipment or systems. Most of these equipment use the manufacturer’s proprietary protocols. The protocols and standards are not unified, and the data structure i...
