Local fan monitoring system static graphic operator can be drawn by the Bureau of the mining side fan monitoring system monitoring system can be connected with maximum capacity: 64 monitoring sub-stations. RS485 or CAN bus two core transfer, transfer rate: 4800bps; FSK bus two core transfer, transfer rate: 1200bps; Ethernet transmission rate: 10M/100M. Ground between the central station to the sub-station maximum transmission distance: 15km; sub-station to the sensor between the maximum transmission distance: 2km. Analog sensor signal :200-1000Hz or 4-20mA and other standard signal; switch sensor signal: potential free contacts and level signals. Power supply: ground equipment is AC220V, downhole equipment is AC127/380/660V. Features: 1, the system has a gas locking function of wind power and the whole mine gas gauge off functions. 2, the system software uses "abnormal changes in value, density combined database dynamically generated" data storage technology, the data storage capacity of hard disk capacity and the computer only has a relationship to solve the problem of data maintenance. 3, the system software has short messaging feature allows you to abnormal data to text message sent to the management staff on the phone. 4, the system is equipped with a dedicated graphics editing software configuration for dynamic graph drawing elements and Roadway. All dynamic and static graphics can be drawn by the mine operator side, while able to CAD, MapInfo two common vector formats into the system, the system supports a variety of graphics formats. 5, the system software has the function of the second data definition. Through the secondary data definitions to implement complex logic. 6, the system can achieve supporting wind power sub-station atresia methane, methane overrun off function. 7, the system supporting the sub-station analog port switch ports are interchangeable, with a large-screen LCD display. 8, system monitoring equipment, supporting sensors, actuators range, the sensor is equipped with remote control, easy adjustment and long life. 9, the system combines the gas drainage pumping station monitoring subsystem, and with my hospital developed KJ236 (A) personnel positioning time and attendance systems and KJF-05 main ventilator-line monitoring system of cable run, no need to repeat the wiring.
