Embodiment Construction

[0044] The concrete realization of this method comprises the following steps, see figure 1 .

[0045] The DCS control system (1) includes the control cabinet (2), the control cabinet (2) includes different types of I / O cards (3), and the I / O cards (3) are composed of multiple I / O channels (4) composition. After the DCS card digitizes the industrial field signals, the data is sent to the DCS engineer station (5) for processing through the network bus, and the DCS system usually provides an OPC server (6), so that the data of the DCS system can be shared.

[0046]It can be divided into two parts, the terminal and the host. The terminal includes a standard signal drive module and related equipment, with a housing, a switch, a built-in standard signal source and its signal output line (for connecting to the I / O channel of the DCS system), Zigbee wireless transmission terminal (for wireless communication with the host); the host includes the OPC asynchronous communication data ac...

Abstract

The invention provides a comprehensive intelligent check method of an industrial distributed control system (DCS) and relates to the field of industrial automatic control. The change or adjustment of an output signal of a remote signal source which is placed at an engineer station is realized by a standard signal source remote driving module, and a high-accuracy standard check signal is provided for an input / output (I / O) sub-module of the DCS; an object linking and embedding (OLE) for process control (OPC) asynchronous communication data acquisition module is realized, and each cabinet, each card and each channel of the DCS are subjected to real-time data acquisition by using a subscription communication mechanism of an OPC automatic interface; and an intelligent check analysis platform controls and integrates the whole check process, sends a check instruction to the standard signal source remote driving module, acquires DCS data information from the OPC asynchronous data acquisition module, carries out analysis and comparison on input output data, and automatically provides a system check result, so the aim of carrying out whole check on the DCS is fulfilled. The method is simple, convenient, unique, high in accuracy, high in efficiency and strong in generality.

Description

technical field [0001] The invention relates to the field of industrial automatic control, in particular to a comprehensive intelligent verification method for an industrial distributed control system. Background technique [0002] Distributed control system is abbreviated as DCS (Distributed Control System), which is a multi-level computer system composed of process control level and process monitoring level, with communication network as the link, used to realize the automatic control of industrial field processes. The basic idea is decentralized control, centralized operation, hierarchical management, flexible configuration, and convenient configuration. [0003] The DCS system can be divided into four parts according to the function, the system communication network, the field process control unit, the man-machine interface and the system configuration tool. Among them, the on-site control unit is the basic component of the DCS system, which is completely oriented to th...
