Coal mine dispatching communication system is mainly used for communication, Inoue coal mine production dispatching command and ground support department. To the coal mine dispatching communication equipment selection, installation, use and maintenance of the correct or not will directly affect the safe production and inspection standard of coal mine enterprises.
Therefore, "Notice of the State Administration of work safety of national coal mine safety supervision of construction to improve mine safety risk" six system "" (total 2010) with coal safety (No. 146) requirements. Provisions of general coal (2007) safety line No. 167 document: the State Administration of work safety, the State Coal Mine Safety Supervision Bureau of all coal mines must immediately install and improve underground communications, emergency water supply system pressure of wind, dust.
Communication system, as its name implies is composed of various related parts, a collection for the implementation of the provisions of the people function to achieve a goal in an interrelated cooperative combat. Associated member each do their job, the system can complete all parts can't finish the work.
Communication scheduling of coal mine communication system consists of two main parts:
1. The main equipment ground control room are respectively composed of: JSQ-31-512 digital program-controlled switches scheduling -- dispatching console -- digital telephone recording system -- backup standby power -- room lightning protection distribution box -- mine phone safety coupler -- well into the communication line fuse and thunder and lightning protection device -- and other components. Ground control room of the core control device is a digital program-controlled switches scheduling and dispatching station, whether its function index reached acceptance standard of coal mine communication system is the selection of the key.
Coal mine communication system an important part of one of the scheduling console, the scheduling table with hardware redundancy, software fault tolerance and perfect, decentralized control, dual power supply seamless switching, effectively ensure the reliable operation of dispatching station equipment. Dispatching station address with "one click a polymorphism", two seats can be a convenient, more than two duty dispatch personnel quickly to determine the global dynamic and command.
Scheduling table has a distress signal alarm, underground distress position display, alarm control center power coal mine communication routine functional system requirements. Dispatching station fire retardant all metal anti interference shielding shell and other sophisticated technology index is dispatching station reliable operation of the guarantee. Design of JSQ-31-512 Denmark key scheduling table in many key scheduling table manufacturers can rise above the common herd.
The 2 part mainly consists of underground:
Fire-retardant communication cable -- mine explosion-proof communication terminal box -- mine intrinsically safe explosion-proof telephone -- mine intrinsically safe communication terminal (including the radio terminal) - and other components.
Underground roadway, Shimen and other members of the general main roadway, mining working face and other personnel intensive construction area, should install the phone terminal.
The main auxiliary shaft winch room, bottom, transportation scheduling room, mining area substation, down on the winch room, pump room, belt conveyor centralized control chamber and other major mechanical and electrical equipment chamber and the mining area, the same level, the highest point above sea level, should install the phone terminal.
Mine refuge chamber (capsule), the main underground water pump room, underground central surface, blasting substation and outburst coal seam mining work evacuees gathering place, mine surface substation and ground ventilation room and coal that frequent contact place, should be installed through terminal equipment mine control room.
Mine refuge chamber (capsule) communication lines within shall be laid in special with signal transmission pipeline anti damage measures.
The key components of intrinsically safe system of coal mine communication scheduling liaison system supporting the use of mine telephone coupler and downhole components should use has been the national mining products safety sign center issued a "permit".
According to "coal mine safety regulations" provisions of the third paragraph: 459th lines of communication must be well arranged at the fuse and thunder and lightning protection device requirements. FL-100 type protector adopts overcurrent, overvoltage fuse box - clamp, lightning surge signal into the relief of multiple protection standard of mine communication system standards. This scheme provides a set of coal mine dispatching communication can meet the standard of mine construction acceptance of the contact system.
Communication system engineering construction technical personnel by the Shanghai New Delhi Communication Equipment Co Ltd organization installation, the production and service process has obtained TLC international quality system certification center certification.
Introduction 5 dispatching communication system:
Dispatch call terminal: terminal telephone call dispatcher calls can be a key to all terminal station in the system.
Scheduling: scheduling emergency call with a call to all "busy" idle "state of terminal station.
The terminal call scheduling: terminal telephone call scheduling. Operation: the off hook dial dispatching number.
Terminal through scheduling: (through) the terminal telephone off hook, no dialing through scheduling table, will automatically call the dispatcher.
Terminal: terminal station by underground emergency call 'emergency call' health, dispatching emergency and underground terminal telephone call is being established.
Terminal alarm: when the terminal issued a distress signal to the dispatcher, dispatching station will be issued a "sound" and "light" alarm signal.
Distress position display: when the terminal issued a distress signal to the dispatcher, dispatching station will be a downhole location display of Chinese.
The scheduling of emergency alarm: underground terminal emergency call scheduling, scheduling according to the alarm button and the distress call.
Scheduling power-off alarm: when the dispatching control center power dispatching station will send the alarm signal.
Terminal telephone dial: between downhole and surface auxiliary department telephone call can dial automatic connection.
Scheduling monitor terminal: terminal A and B is on the phone, insert the monitor and record the dispatcher.
Scheduling in demolitions: terminal A and B are calls, scheduling can be forced into a call or forced to interrupt a and B call.
Dispatch call group call: scheduling three party, square or N terminal telephone and call or broadcasting.
Dispatch call all call: scheduling the subregional emergency calls and radio terminal underground area. Or a call entire underground terminal.
The scheduling of emergency broadcast: Emergency Scheduling can be issued an emergency notice to the address terminal or issued an emergency evacuation instructions to the underground.
Time query function: Ishita Renichi terminal telephone can query the current time by voice mail.
