Description
Technical field:
The present invention relates to technical field of mine safety more particularly to a kind of coal mine safety monitoring system Grading And Zoning alarm sides
Method and safety monitoring system.
Background technique:
Existing coal mine safety monitoring system only realizes the pre-alarm of single parameter, does not consider that the data of sensor monitoring are different
Normal duration factor etc. can't fully meet the needs of mine safety production management, therefore propose Grading And Zoning report
Police's formula, to realize in different ways to the portion of different stage in the different degrees of disaster of variety classes or failure generation
Door sends the function of warning message.
According to safe and scientific theory, according to effect of danger source during accident occurrence and development, danger source is divided into
A kind of danger source and the second class danger source.First kind danger source refers to present in production process, it may occur however that surprisingly discharges
Energy (energy or energy carrier) or dangerous substance；Second class danger source refers to that causing energy or dangerous substance to constrain or limit arranges
The various factors of destruction or failure is applied, (environmental factor causes the event of object for the main failure including object, the fault of people and environmental factor
The fault of barrier and people).
What coal mine safety monitoring system mainly monitored is first kind danger source, and when there is the second class danger source, (methane is super
Limit, damper faults, electromechanical equipment failure etc.), system automatic alarm.It is only quasi- to individual single danger source setting early warning at present
Then, do not comprehensively consider all kinds of danger sources, realize the early warning of Grading And Zoning domain.
Summary of the invention:
For the function of promoting monitoring system, need to comprehensively consider all kinds of danger sources monitored, the purpose of the present invention is needles
To the defect of the prior art, a kind of coal mine safety monitoring system Grading And Zoning alarm method and safety monitoring system are proposed.
To achieve the above object, a kind of coal mine safety monitoring system Grading And Zoning alarm method provided by the invention, including
Following steps:
Step 1: listing the danger source that monitoring system can monitor；
Step 2: danger source is divided into different brackets according to degree of risk by the degree of risk of evaluation danger source；
Step 3: setting single danger source forecasting criterion (being similar to existing alarm mechanism)；
Step 4: different weights is assigned according to danger source grade, in conjunction with single danger source forecasting criterion, set comprehensive
Grading forewarning system criterion；
Step 5: carrying out classifying alarm according to comprehensive classification forecasting criterion；
Step 6: setting the system control measure of different warning levels.
In step 1, the danger source includes gas accident, ventilation blower failure, CO poisoning and damper faults etc..
In step 2, danger source is divided into level Four, severity successively aggravates, including zero level alarm, level-one alarm, second level
Alarm and three-level alarm.Monitoring parameters critical value requires according to national standard and coal mine management, is practical between each alarm level
Infield requires to be configured, or is obtained according to the measuring point historical data analysis model dynamic.
In step 3, the single danger source forecasting criterion differentiates according to single-point parameter, according to corresponding alarm sensor
Installation site determines that the sensor mounting location region is danger zone, and alert levels are identical as sensor alarm rank,
It take the single danger source alert levels of highest as the alarm in the region if the same area has several single danger sources with alarm
Rank, danger source influences and affected area is determined by different danger source characteristics, home environment.
In step 4, the comprehensive classification forecasting criterion is occurred according to multiple spot, multi-parameter Identification according in the same area
All single danger source grades, assign different weights, in conjunction with single danger source forecasting criterion, obtain the comprehensive report in the region
Alert rank.
It is remote by downhole sensor itself, combined aural and visual alarm, ground monitoring center, SMS platform and group in step 5
Journey monitoring center carries out classifying alarm.
The present invention also provides a kind of security monitoring systems for above-mentioned coal mine safety monitoring system Grading And Zoning alarm method
System, including group's remote monitoring center, ground monitoring center, underground interchanger and downhole monitoring substation, the group remotely supervises
Measured center and ground monitoring center cluster, the ground monitoring center pass through ground ring exchanger and underground ring exchanger point
It does not network with each outstation, each outstation is respectively equipped with sensor and alarm.
After adopting the above technical scheme, the present invention have the effect of it is following positive: the coal mine safety monitoring system classification point
Area's alarm method and safety monitoring system carry out advanced prediction to coal working face gas density, carry out gas to driving face
Prominent early warning is alarmed according to classifying alarm, power-off strategy, is powered off, when alarming, issues voice sound-light alarm, root
Short massage notice is sent to related personnel according to classifying alarm rank, to ensure that production safety management demand.
Detailed description of the invention:
Fig. 1 is the schematic diagram of safety monitoring system of the invention.
Specific embodiment:
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
