Problems solved by technology

The existing OPC client technology based on the Linux operating system is based on the X86 hardware architecture, which has the same hardware architecture as the management network. Therefore, viruses can easily attack the industrial control network by using this loophole, which greatly affects the security of the industrial control network. big threat

Abstract

An optical proximity correction (OPC) embedded-type remote data collecting system and a method based on ARM framework comprise an OPC client, an OPC server, a communication server, a real-time database and a data processing module. The invention provides an OPC embedded-type remote data collecting system based on ARM framework, remote data collecting from an industrial control network is achieved and the collected data is sent to the real-time database of a managerial network. Due to the fact that the industrial control network and the managerial network are safely isolated from a hardware architecture and an operating system, virus on the managerial network is prevented from attacking the industrial control network and the safety of the industrial control network is guaranteed. The OPC embedded-type remote data collecting system based on ARM framework is multifunctional system integrating the data collecting and the security isolation.

Description

technical field [0001] The invention relates to the technical field of data acquisition, in particular to an OPC embedded remote data acquisition system based on ARM architecture. Background technique [0002] In the field of industrial control, the system is often composed of scattered subsystems, and each subsystem uses equipment from different manufacturers. Since there is no uniform standard for the interface between the hardware driver and the application program connected to it, it is necessary to develop different drivers. Since the coexistence of various drivers in the system also makes it more difficult to maintain the stability and reliability of the operating environment, OPC standardizes the software interface between devices and applications from different vendors. [0003] OPC or OLE (ObjectLinking and Embedding) is a communication interface standard used in the field of industrial control, which provides a set of standard interfaces, attributes and methods fo...
