Based on certain mining companies as the research object, aimed at the scene of the heterogeneous system integration requirements, compare the OPC standard with the current process control industry standard of automatic monitoring system, and compare with the transport layer in the industrial Ethernet TCP, UDP protocol, is put forward based on the OPC server, based on TCP/IP transport layer, and application layer scalable heterogeneous system integration solutions, presents a heterogeneous system integration with industrial Ethernet and OPC technology solutions, engineering practice shows that the scheme made the data transfer and sharing between heterogeneous platform, provides the enterprise automation transformation and upgrade of the feasibility of the effective ways, In the modern industrial production, in order to ensure all sorts of equipment to play a full part in the control system in order to realize the coordination effective running of the control system as a whole, system integration has become more and more get the attention of the people, the OPC technology, object linking and embedding technology applied in the field of industrial process control, create conditions for the integration of the industrial control network, the OPC specification mainly distributed component based on COM technology, the control network of horizontal and vertical integration, solve the problem of the network transmission uncertainty, Mentioned system integration, however, is inevitable to mention information island, information island make the huge loss of information resources, precipitation, can't give full play to the information in the lower control and the leading role of top management decision, "information island" is gradually along with the development and application of the industrial control configuration, a single system running effect of impeccably, but each system is difficult to do a larger integration, so how to integrate the heterogeneous group of industrial control system, get the attention of people, Protocol gateway communication technology based on the information network for the purpose of information and data sharing, with the ultimate goal is to realize the effective control of controlled object, make the system safe and steady operation, is rich of agreement, safe and reliable, good error correction etc., can be tightly integrated control network and information network, the optimal control for the enterprise, to provide basis for decisions on scheduling is the foundation of building enterprise integrated real-time database, through the combination of control network and information network, can build a uniform distributed database, ensure the integrity of all data and interoperability; Real-time communication field devices with information network, the user through information network in the standard graphical interface understand production situation anytime and anywhere, in real time monitor the running situation of production system, Our OPC protocol gateway, the Internet can make the system safe and reliable communication, it can effectively solve the DCOM configuration brings some headache, when different regions, different geographical location, the need for data sharing between different security Settings of system, you only need to in local OPC server network installation configuration of our OPC protocol gateway, then simple set to connect the OPC server and to docking platform, the data can be realized in seamless transfer, management integration of historical data, so simple, it is a set of mature, "plug and play" solution, it supports multiple OPC platform based on the OPC standard, this solution is perfect for those who need in different geographical location, accuracy and integrity of data collecting zone and may need data transmission project, For vendors need data analysis process, it is an economical and practical, cost-effective, software installation configuration and management are very simple protocol gateway products, large enterprises need to meet the demand of the enterprise all kinds of real-time database, and its different is that our OPC protocol gateway model of product more targeted, more flexible to use, it focuses on the data collection, rather than data show, for the user needs to analyze process data, cost-effective, easy to install, debug and maintain, it is a set of processing process of heterogeneous network data portable solution, can be used alone, also can be used as part of the enterprise mass data storage, Our OPC protocol gateway system scheme, the default support OPC foundation of OPC Security communication protocol (OPC Security Specifications), giving users can be set up for each data point is different: to read, write and the ability to add (data points), the solution to the user without having to replace or disrupt existing OPC component and architecture, can have a worthy of trust of Security communication system, OPC protocol gateway sample solution topology, as follows:
