Problems solved by technology

However, for a large-scale production line with a production capacity of about 5000t / D, the factory covers an area of ​​300,000 m2, and the I / O signal is nearly 10,000 points, and the debugging workload increases several times. According to the conventional debugging method, the cost of manpower and time increases sharply, and Work efficiency is low.

Embodiment Construction

[0047] Such as figure 1 Shown: a large-scale dry cement decentralized control system group joint debugging method, characterized in that it includes the following steps:

[0048] Step 1: Partitioning and grouping

[0049] According to the cement production process and the regional distribution of equipment, the main control stations such as raw material allocation, raw meal mill, coal pulverization, firing kiln, cement mill, slag mill, cement allocation, finished product warehouse, and cement packaging will generally be arranged on site. Overall, it can be divided into three areas:

[0050] 1) Limestone storage yard, raw material allocation, and raw meal mill are one area, and its raw meal homogenization warehouse is a buffer zone for process connection;

[0051] 2) Coal powder mill, firing kiln, cement mill, and slag mill are one area, and its cement clinker warehouse is a buffer zone for process connection;

[0052] 3) Cement blending, finished product warehouse, and ceme...

Abstract

The invention relates to a grouping and joint debugging method for a large-scale dry method cement decentralized control system. The method includes the following steps: a first step of regionalizing and grouping: based on a cement production technology flow and device region distribution, dividing the entire site into three large regions and grouping devices, control stations that have continuous relationship or interlocking relationship in technology order, or complete devices that are relatively independent within each region; a second step of conducting joint debugging among regions and groups: (1) conducting joint debugging between each group I / O signal and the decentralized control system; (2) performing single-machine simulation controlling and parameters, algorithm adjustment and debugging; (3) conducting grouping device single testing and examining; (4) starting up the device complete set; (5) conducting regional interlocking; and after regional interlocking of each region meets requirements, based on the technology flow, beginning the entire line cooling load test run. The method of the invention increases on-site debugging efficiency, shortens debugging time, reduces labor and time cost, and increases economic benefits.

Description

technical field [0001] The invention relates to a method for group joint debugging of a large-scale dry-process cement dispersion control system. Background technique [0002] Due to the technical characteristics of the dry process cement production line, its main production equipment is relatively scattered, so most of the dry process cement production lines now use "distributed control system (DCS)" to achieve decentralized control, centralized operation, and hierarchical management. [0003] For the small-scale dry-process cement production line, according to the technological process of the production equipment, I / O tests are performed on all equipment in turn; after the I / O test is completed, the stand-alone test run and program adjustment are carried out step by step through the process control station; and then the process is controlled through the operation station. Operation monitoring and operation; finally, all equipments are linked to test run, which can effectiv...
