Abstract

The invention discloses a method and a device for collecting the data of the equipment of a third party in a distributed control system. The method comprises the following steps of: receiving a call request to the equipment of the third party by an OPC interface, wherein the call request is transmitted by an OPC client and carries the label information of the equipment of the third party; calling drive modules in a plurality of preset drive modules, which correspond to the communication protocols of the equipment of the third party, according to the label information and constructing connection with the equipment of the third party; and collecting the data of the equipment of the third party and carrying out the corresponding processing on the obtained data of the equipment of the third party. By the invention, the connection of the distributed control system and the equipment of the third party applying various communication protocols can be met.

Description

technical field [0001] The present invention relates to the technical field of industrial automation, more specifically, to a method and device for collecting third-party equipment data in a distributed control system. Background technique [0002] With the rapid development of new technologies such as computer science and industrial control, the computer monitoring system has developed from the early centralized monitoring to the fully distributed direction. The maturity of Server) technology makes the computer monitoring system software develop from an early function-oriented system to an object-oriented computer monitoring system characterized by oriented to specific field devices. [0003] Data and information are the basis of the supervisory control of the Distributed Control System (DCS), and they not only come from the DCS field control layer, but may also come from third-party equipment and software. A good DCS monitoring application software should be able to provi...
