Abstract

The invention discloses a DCS data communication system of a heterogeneous communication network. The DCS data communication system comprises a HoneyWell PKS, an ABB AC800M system, an EMERSON DeltaV system, an upper monitoring system, a power module and a data processing module. The data processing module comprises a controller and an information storage module. The data processing module is provided with a DeviceNet communication interface, a PRFIBUS-DP communication interface and an MODBUS-RTU communication interface. The controller is connected with the upper monitoring system through an EtherNet / IP interface. According to the DCS data communication system of the heterogeneous communication network, DCS systems based on the heterogeneous network are integrated, and real-time communication and testing among the systems are achieved. Thus, upgrading and maintaining of the system are convenient, and hardware cost of the system is reduced; due to the fact that the DCS data communication system can automatically identify the Baud rate and the station address of system communication, the debugging configuration process of the system is simplified.

Description

technical field [0001] The invention relates to the technical field of offshore oil equipment control, in particular to a DCS data communication system of a heterogeneous communication network. Background technique [0002] Nowadays, in the offshore oil industry, DCS systems are widely used in the control of offshore platforms and land production processes. At present, the PKS system developed by Honeywell itself supports EtherNet / IP protocol, DeviceNet protocol communication, etc.; the AC800M system developed by ABB supports FF bus, PROFIBUS-DP protocol communication, etc.; the DeltaV system developed by EMERSON supports FF bus, DeviceNet protocol, and Communication of MODBUS-RTU protocol. To sum up, it can be found that the DCS systems developed by different companies support different communication protocols. If communication between them is required, additional communication modules produced by third-party manufacturers need to be purchased. If a one-to-one gateway is ...
