Description
Technical field
The present invention relates to a kind of large-scale cement produced with the dry method scattered control system packet joining adjustment methods.
Background technology
Due to the process characteristic of dry cement production line, main production equipments are more dispersed, so most dry method now
Cement producing line uses " Distributed Control System（DCS）" to realize the efficiency such as decentralised control, centralized operation, multi-zone supervision.
For small-sized dry cement production line according to the technological process of production equipment, I/O surveys are carried out to all devices successively
Examination；Substep carries out solo test run by process control station again after the completion of I/O tests, program adjusts；Then by active station to work
Skill process operation monitors and operation；Last all devices carry out linkage trial run, can efficiently accomplish debugging efforts.But for production capacity
The large-scale production line of 5000t/D or so, plant area take up an area up to 300,000 m2, nearly 10,000 points of I/O signals, and debugging work load increases several times,
Adjustment method routinely is debugged, and manpower, time cost increase sharply, and the low of working efficiency
Invention content
The present invention is directed to overcome the deficiencies of existing technologies, a kind of large-scale cement produced with the dry method scattered control system packet joining is provided
Adjustment method improves field adjustable efficiency, shortens debug time, reduces manpower, time cost, increases economic efficiency.
In order to solve the above-mentioned technical problem, the invention is realized in this way：
A kind of large size cement produced with the dry method scattered control system packet joining adjustment method, which is characterized in that include the following steps：
Step 1：Subregion, grouping
It is distributed according to cement production process flow and equipment region, scene is overall to be divided into three regions：
1) lime stone stockyard, material allocation, raw mill are an area, and raw material homogenizing silo is the buffering area of technique linking；
