Abstract

The invention discloses a data acquisition device and method based on a dual-mainboard architecture. The dual-mainboard architecture is composed of an X86 mainboard and an ARM mainboard. The OPC Server developed on the X86 mainboard includes a startup module, a label point receiving module, and a label point processing module. , label point release module and data processing module; OPC Client developed on ARM motherboard includes acquisition module and data transmission module. The data acquisition device based on dual motherboard architecture and heterogeneous operating system prevents the spread of malicious programs such as viruses between the industrial control network and the management network, and improves the security of real-time data acquisition in the industrial control system.

Description

technical field [0001] The invention relates to the field of industrial process optimization control, in particular to a data acquisition device and method based on a dual mainboard architecture. Background technique [0002] OPC (OLE for Process Control) is OLE (Object Linking and Embedding), a communication interface standard used in the field of industrial control, which provides a set of standard interfaces, attributes and methods for process control. OPC uses Server and Client to communicate, where Client is responsible for requesting data, and Server responds to the request and provides data. The emergence of OPC enables devices and drivers from different manufacturers to connect and exchange information flexibly, thus greatly improving the openness and interoperability of process control devices and data acquisition systems. [0003] The development of industrialization and informatization has realized the close integration of traditional computer network and industr...
