Embodiment

[0048] No. 1 sintering machine of an iron factory uses Honeywell PKS DCS, and its control system provides an OPC data interface; No. 2 and No. 3 sintering machines use Yokogawa CS1000 DCS, and its control system provides a DDE data interface.

[0049] First, the data interface of the control system of No. 1 sintering machine and No. 2 and No. 3 sintering machines is connected to the data input interface of the data collection and processing device 1 of the present invention through the local area network mode, see figure 2 . The real-time data provision methods of the control systems of No. 1, No. 2 and No. 3 sintering machines are OPC mode and DDE mode respectively, corresponding to the OPC Client and DDE Client of the data input interface of the processing device 1.

[0050] Then, according to the collection requirements of different real-time data, the user sets parameters such as the tag name of the sent data, the type of the sent data, the effective length of the sent da...

Abstract

The invention discloses a method and a device for data acquisition and processing of a multiple industrial-control computer system platforms. The processing method comprises the following steps of: 1. acquiring various data on all industrial-control systems by connecting an data input interface with an industrial-control control network; 2. statically configuring data based on the acquired industrial-control data, and storing the statically configured data in a data storage module; 3. carrying out encoding processing on acquired real-time data in a data processing module according to encodingrules; and 4. transmitting data processed by the data processing module to a third-party application program or system through a data output interface according to the UDP (User Datagram Protocol) protocol. The invention can effectively improve the data acquisition and processing modes of the third-party application program or system for various kinds of industrial-control system software, and solves the problems of difficult data acquisition and processing caused by nonuniform formats of different industrial control computer system data and the like, thereby enhancing software development efficiency, and decreasing software development difficulty.

Description

technical field [0001] The invention relates to a data acquisition technology for industrial automation control, in particular to a data acquisition and processing method and device for a multi-industrial control system platform. Background technique [0002] There are many types of existing industrial control system brands. Due to inconsistent data formats, their external interfaces are inconsistent. The main interfaces include OPC interface, DDE interface, MODBUS interface and other non-standard interfaces. Existing third-party application software or systems must choose different communication methods and data processing methods to communicate with different industrial control systems. [0003] Although the application of communication middleware partly solves the problem of unification of communication mode and data processing method, but because the communication middleware must use text to communicate, the data must be processed in the industrial control system before ...
