Abstract

The DCS data collection uses DCS and server with real-time data base installed, and features that via one increased DCS interface, remote DCS data are teal-time collected into computer network through data communication and access between DCS and server, driving the real-time data base to collect and screen DCS, and automatic renewing of data in the data base. The data are then processed for analysis and management. The present invention can raise work efficiency and lower investment through remote data collection.

Description

Technical field

[0001] The invention provides a method for collecting DCS data into a computer network in real time, and in particular relates to a remote collection method for DCS data in petrochemical enterprises. Background technique

[0002] DCS refers to the distributed control system, which is used for industrial control. It becomes a system by itself, including history station, engineer station and multiple workstations. To collect the data of each workstation in each DCS in real time, the data interface of DCS must be established. Currently ASPEN, which develops the INFOPLUS21 real-time database, has developed most DCS data interfaces, such as Honeywell's TDC3000, ABB's MOD300 or OCS data interfaces, which can realize remote real-time collection of DCS data into the computer network, and then process them Analysis, used by decision-making managers, lays the foundation for the decision-making command department to make correct dispatching orders in a timely manner ac...

Embodiment Construction

[0016] Server 1 and multiple DCSs are networked using TCP / IP protocol to realize mutual communication and access of data. The real-time database installed in it adopts INFOPLUS21 real-time database, and the database link of SQLnet, ODBC and INFOPLUS21 is used in the INFOPLUS21 server to use SQLplus The statement directly sends the result of the query to the INFOPLUS21 database. Each DCS includes a history station, an engineer station, and multiple workstations. In each DCS, only the history station is set with a gateway, and the write-back function of the DCS operation data is limited, so as to ensure the safety of the DCS control and prevent accidents. The impact of DCS. The DCS system is ABB OCS V1.6 / 3.

[0017] The configuration and steps are as follows:

[0018] Install SQLnet------------------------------------Install Oracle-for-win9X / NT on INFOPLUS21 server .

[0019] Configure SQLnet parameters: database alias ---------- HOHP-SQLNET

[0020] Connected hos...
