Abstract

The invention belongs to the technical field of industrial automation, in particular to a distributed type control system and method used for a large reciprocating type compressor group. The control system structurally comprises a main controller, an MPS system, an ESM system, a communication system, remote I / O, local I / O, HMI, a field sensor, a performer and the like, wherein the communication system, the MPS system and the ESM system are a slave controller; the slaver controller performs an instruction of the main controller; the main controller is in communication with the local I / O througha backboard bus for directly monitoring the field sensor and controlling the performer; the main controller is connected with the MPS system, the communication system and the like through field buses, and is in communication with the remote I / O for directly controlling the field sensor and the performer. The control system performs reasonable modularized integrated grouping on conventional intensive type control, adopts a combined form of the remote I / O, the main controller and the field bus to perform reasonable function dismounting, so that the parts are distributed on every parts of the unit, so that the problems such as difficult explosion protection, disorderly ordering, poor maintenance and weak performance are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of industrial automation, and in particular relates to a distributed control system and method for a large reciprocating compressor unit. Background technique [0002] With the continuous improvement of environmental protection requirements and the implementation of large-scale coal-to-gas conversion, the demand for natural gas compressor units continues to increase, and the performance requirements for natural gas compressors continue to increase, especially large reciprocating compressor units. [0003] Large-scale reciprocating natural gas compressor unit is a common equipment for natural gas pressurization, and is widely used in petroleum, chemical, gas filling stations, booster stations and other places. The large reciprocating compressor unit has the characteristics of large processing capacity, many modular skids, many instrument measuring points and wide distribution, independent MPS system, and the ...
