Since the 80s of the 20th century, Changzhou Automation Research
Institute of China Coal Technology & Engineering Group Corp has
developed many monitoring and control systems for coal mine, such
as KJ1, KJ2, KJ22, KJ12A and KJ95, which have been awarded with
scientific and technological progress prizes of national,
ministerial and provincial class and more than 1000 complete sets
are operating in mining bureaus and coal mines in China and other
countries such as Bengal, India, Turkey and so on.
Model KJ95N Integrated Monitoring and Control System for Coal Mine
is developed with advanced technologies of computer network, ARM
and EMC anti-interfering based upon our previous monitoring and
control systems for coal mine. The system can monitor, display,
alarm and control various parameters of environment and production
of coal mine and methane drainage process, and it is suitable for
small, medium/large-scaled coal mines. |
|
| | The system conforms to AQ6201-2006 General Technical Requirements
of Safety Monitoring and Control System for Coal Mine and related
industrial standards; | | The system can monitor and display environmental parameters such as
methane, air flow, negative pressure, carbon monoxide, smoke,
temperature, air-door and so on, and have functions of failure
locking and alarming, local or remote over-limit power-off,
interlocking of air, electricity and gas, etc; | | The system can monitor and display production parameters such as
coal level of bunker, water level of sump, air pressure of air
compressor, count of skip bucket, start/stop of electromechanical
equipment, and have function of failure alarming; | | The system can monitor and display methane drainage process; | | The system has function of information indication and guide,
decentralizedly displaying event plan, related parameters and
lifesaving routine guide, sending voice alarm in coal mine wide; | | The system software has functions of parameters setting, control,
page editing, display of forms, curves, histogram and analog
diagram, printing and inquiring. | | | | Advanced technology with various transmission modes such as
transmission interfaces, optical terminal for data, industrial
Ethernet, etc. | | Simple and reliable transmission network with standard network
transmission protocol, high transmission rate, low error (less than
10) and long non-repeater transmission distance. | | Good compatibility and openness of the system software which is
based upon Microsoft COM/DCOM technology and client/server
structure. | | On-site calibration and setup of sensors and general management and
maintenance of Intrinsically Safety UPS. | | All the main devices of the system have passed related
electromagnetic compatibility test. | | | | System Capacity: 128 outstations | | Transmission Media: Cable, optic fiber cable | | Transmission rate: 1 200 bit/s | | Transmission distance between surface center and outstations15
km(cable), 20 km (optic fiber cable) | | |
