Description
Technical field
The utility model relates to PLC control technology, sensing technology, Network Information technology, the administrative skill of Computerized intelligent,
It is specifically related to the PLC control system of safety of coal mines air door winch monitoring, in particular, relates to the colliery that a kind of PLC controls
Relief damper winch monitoring system.
Background technology
" safety regulations in coal mine " the 158th article of clear stipulaties: " all mines must be provided with Safety Monitoring Control System of Coal Mine.
The mounting, commissioning and maintenance of Safety Monitoring Control System of Coal Mine has to comply with the requirement of this code and relevant regulations.”
Since two thousand, along with coal mining enterprise's safety in production requirement is improved constantly and the needs of enterprise's self-growth by country,
The high methane in each large, medium and small colliery of China or Gas Outburst mine are successively in equipment monitoring mining monitoring system.The equipment of system
Substantially increase mine safety production level and production safety management efficiency, the most also for correctly the selecting of this technology, use, tie up
Protect and have higher requirement with enterprise safety operation information system management.
Coal Mine Safety Monitoring Systems is a kind of can automatically to gather and process data the system controlled accordingly.It can
Realize methane transfinite power-off, blowing-out power-off, ventilating system monitoring, coal and gas prominent forecast, fire monitoring and forecast,
Floods monitoring and forecast, mine pressure monitoring and forecast etc., thus reduce gas and coal-dust explosion, fire, floods, top board etc.
Disaster accident occurs, and effectively ensures Safety of Coal Mine Production and miner's life security.
According to existing documents and materials: KJ90 moulded coal ore deposit relief damper winch monitoring system from the most successfully develop and introduce to the market with
Come, through constantly improving and development, have evolved at present reach the new standard-required of AQ6201-2006, based on industry ether ring
6th generation product-KJ90NB safety monitoring system of net platform, develops into collection environment from Coal Mine Safety Monitoring System in early days
Safety, production monitoring, information management, network application, industrial television and compatible gas drainage under suction, fire monitoring, power network monitoring,
The New Coal Mine comprehensive monitoring system that many subsystem such as top board dynamic monitoring, main fan on-line monitoring are integrated, this system with
Its technical advance and practicality are welcome by coal mine user deeply, have obtained good popularization and application at coal industry, and at other
The civilian aspects such as the such as environmental protection, chemical industry of non-coal industry, highway and railway tunnel are applied.Up to the present, the most
Individual provinces and regions, system domestic market occupation rate is more than 50%, and user generally reacts good, achieves preferable economic benefit and society
Can benefit.
KJ90NB moulded coal ore deposit relief damper winch monitoring system is strong from ability to provide the auxiliary items, the various kinds of equipment of monitoring system and monitoring software
By the development of one, Chongqing Mei Ke institute, produce.Product cost is high, and after-sale service is secure, can well control monitoring system
Oeverall quality and performance, control the production and processing cycle of product, and the upgrading to product in the future provides reliable guarantee.
Traditional safety monitoring system uses the mode of bus transfer, and power system capacity is limited, and communication platform can only run specific system
System, reflection speed is slow, does not possess communication redundancy and self-recovering function；Easily it is disturbed, fluctuation of service；Poor compatibility；Cannot
Realizing failure self-diagnosis, self-organizing system, data are isolated and repeat wiring, and working service workload is big, it is impossible to carry out total score
Analysis, early warning, emergency cooperative.
According to being actually needed of each ore deposit production management in recent years, also some new systems will be equipped in the mine each link of raw coal production process.
If continuing to use traditional communication modes, Mine Monitoring equipment cloth certainly will be caused again by using respective independently installed operating scheme
Line becomes increasingly complex, system maintenance cost is increasing.
At present, safety of coal mines air door winch monitoring system is found broad application in China's coal-mine.Practice have shown that, safety of coal mines
Air door winch monitoring system is Safety of Coal Mine Production and management serves highly important effect, and each office ore deposit is as a great peace
Full equipment.Due to quite a few monitoring and controlling system at that time owing to technical merit is low, function and scalability is poor, field maintenance
The reasons such as maintenance and technological service do not catch up with, or eliminated or stopped production.Thus result in quite a few mine cannot continue
The furnished system of normal use.Near due to the legacy system length of service the most in recent years, without continuing necessity of maintenance maintenance,
The opportunity that systems face renovates.
Therefore, the safety of coal mines air door winch monitoring system using PLC to control carries out the intelligentized control method of safety of coal mines, traditional
Safety of coal mines air door winch monitoring system has the disadvantage in that
(1), traditional safety of coal mines air door winch monitoring system do not use industrial computer, PLC to be controlled, its control
Mode poor effect processed, it is not easy to realize the informationization of coal mine ventilation door winch shear start and stop monitoring, the control of automation；
(2), traditional safety of coal mines air door winch monitoring system do not use fabricated structure, its composition structure do not include industry control
Machine, PLC control system, external device, air door winch device, sensor, circuit part, air door winch monitoring system, its
Combining structure is more complicated, operation is inconvenient；
(3), traditional safety of coal mines air door winch monitoring system does not use air door, airdoor control cabinet, air door winch, air quantity
Control poor effect, there is many potential safety hazards the most simultaneously, it is wasted time and energy, inefficiency；
(4), traditional safety of coal mines air door winch monitoring system does not use Air door sensor, equipment on/off transducer, wind speed
Sensor, the signal of air door, equipment start-stop signal, wind velocity signal Detection results are the best；
(5), traditional safety of coal mines air door winch monitoring system does not use monitor client, it is impossible to realize Safety of Coal Mine Production
Information-based monitoring；The most not using memory, its storage effective scope is the widest, it is impossible to saving manpower, production efficiency is relatively low,
More can not produce good economic benefit and social benefit.
