Description
Technical field
The present invention relates to a kind of control method and device, are more particularly to a kind of control method and device of extraction system.
Background technique
With the development of coal mining technique, the coal gas contained in coal seam is carried out using being also very important research side
To.In the extraction system of coal mine, the monitoring extraction server software for monitoring extraction system is on each extraction pipeline
Flow sensor defines, data acquire, the software of extraction amount statistics, provides and closes to the extracting result in each extraction place
The basic data of evaluation is managed, is administered for mine gas and safe working provides significant data foundation.
Currently, in existing extraction system, once define four pipelines of the flow sensor of some place pipeline
After sensor parameters, then the software has just automatically begun to the acquisition of extraction pipeline data and the statistics of extraction amount, automatically generates every
Its extraction amount report and the every month to date extraction amount report of generation.
In actual operation, extraction pipeline usually can need temporarily to stop to take out because of various real work situations.For example, working as certain
A extraction point needs pipeline temporarily to stop to take out, and after being closed due to flow sensor, needs to reconfigure each flow sensor,
And then a large amount of time can be wasted, and the report of the flow sensor after reconfiguring can not be right with the report before reconfiguring
It answers.Therefore, it is common practice to close pipeline gate valve, ideally, pipeline gate valve is once closed, in pipeline there will be no
Gas Flow, flow sensor are just detected less than flow.Since the gate valve having causes the reality that is not closed completely because corroding for a long time,
The phenomenon that there are gas leakage.Further, not bery serious no replacement is required the gate valve of some gas leakage situations or be inconvenient to replace gate valve
Therefore, in pipeline situation will continue to the presence of gas air-flow, the flow sensor in pipeline will continue to measure, and continue to generate
The extraction amount data of the extraction point will continue to generate.But in labour statement, the pipeline of the extraction point is had been off,
Corresponding extraction flow is zero, ultimately causes extraction amount report that flow sensor automatically generates and labour statement's data are different
It causes, causes gross error.
