KJ90NA comprehensive monitoring system for coal mine safety
This system is developed independently in Chongqing coal ASTRI brand products, has been widely used in China's coal industry, for many years the market share of the first, good reputation, well received by the user welcome coal mine. At present it has been applied in domestic thousands of sets, users across Sichuan, Yunnan, Guizhou, Shanxi, Shandong, Henan, Hebei, Anhui, Jiangsu, Heilongjiang, Xinjiang, Qinghai, Gansu, Ningxia, Inner Mongolia, Guangxi, Shaanxi, Chongqing and other regions. Once won the ministerial level scientific and technological progress award.
(1) system:
Using time-division distributed structure, mainly composed of a ground monitoring host, database server, network terminal, graphics workstation, communication interface, lightning arrester, series of monitoring substation, various sensors and actuators and other components. A set of mine safety monitoring, production condition monitoring content as one of the mine safety production monitoring system.
(2) the main features:
1) system fully meet the new AQ6201-2006 monitoring system of coal mine industry standards, the first domestic completely according to the new standard of monitoring system of coal mine safety standard certificate.
2) products from the strong compatibility, a series of complete, high ratio of performance to price, a full set of system equipment from Chongqing coal ASTRI independent R & D, manufacturing, customer service service has safeguard.
3) is open and scalable, modular design, flexible configuration. Optimization of monitoring system can meet the various types of mine's economic operation.
4) Ethernet to run the ground control center in the standard
TCP/IP network environment, operating system platform for Chinese Win98/2000/2003, can easily realize the information sharing and interconnection of network. Integrated monitoring system information for Web Internet/Intranet model to support browsing.
5) system using text, graphics display screen compatibility mode, display information intuitive, vivid, has the function of real-time multi screen display.
6) with real-time data storage and various statistical data storage capacity. Data stored for a long time, query and reporting functions, by the user's editing format.
7) a series, multi-purpose monitoring, feature rich, full functionality with methane breaker and methane wind electricity locking device. A perfect data outage preservation ability, to ensure that the information of monitoring data and setting data is not lost. Equipped with a smart mouth, can be used in a variety of sensor and RS485 communication mode.
8) when the communication line line, substation can save more than 2h of data, the communication line after recovery, automatic data up to the central station.
9) substation and sensor the full realization of the intelligent infrared remote control to adjust the settings, and. Substation simulation and switch ports can be freely exchanged, and supports a variety of signal system, real-time data storage capacity.
10) substation power supply with a wide range of dynamic adaptive capability, suitable for harsh environment of mine power network fluctuation. The standby battery can ensure the power supply capacity of more than 2h.
11) unique three power control and super off-site power capacity (hand control, station control and sensor local control center). With power feedback information, if abnormal, alarm.
12) sensor range, fully meet the new AQ sensor series of industry standard, has the advantages of high stability, long life, low power consumption, transmission distance and so.
13) has the function of self checking, the diagnosis can be carried out on the substation, power supply, sensor, cable and other equipment, alarm and recording and automatically cut off the fault branch. A multilevel password perfect protection function.
14) system with fault perfect locking function, when the locking and related equipment are not put into normal operation or failure to cut off power when the equipment with and atresia.
