A mine emergency and daily dispatch communication network system

Abstract

The invention relates to a mine emergent and daily dispatching communication network system which solves the problems that existing mine communication facilitates cannot meet daily commanding and dispatching, personnel positioning and mine up-down communication contact or do not have the basic communication function under the emergent situation. The mine emergent and daily dispatching communication network system comprises an overground communication unit and an underground communication unit. The overground communication unit comprises a computer and an overground ground penetrating communication device. The computer is used for sending control dispatching information to the overground ground penetrating communication device, receiving underground working state information sent by the overground ground penetrating communication device and displaying the underground working state information. The underground communication unit comprises N underground switching devices and M handheld terminals, wherein the M and the N are integers, the N is larger than or equal to 4, and the N is smaller than or equal to the M. According to the mine emergent and daily dispatching communication network system, underground communication is achieved by the adoption of a local area network, implementation is easy, the cost is low, and compared with an existing well emergent and daily dispatching communication network system, the year-to-year cost is reduced by more than 10%.

Description

technical field [0001] The invention relates to a mine emergency and daily dispatching communication network system which solves the problem that the existing mine communication facilities cannot not only meet the daily command and dispatch, personnel positioning, communication between the upper and lower mines, but also have basic communication in emergency situations. Background technique [0002] At present, the mine communication system mainly includes power line carrier communication, medium frequency induction communication, VHF leakage communication, cell cellular mobile communication, mining PHS wireless communication and low frequency ground-penetrating communication. Traditional communication systems use proprietary communication lines or existing power lines and use lines such as wireless channels as communication links. [0003] Traditional communication methods can meet the needs of daily command and dispatch, personnel positioning, and communication up and down...

AI Technical Summary

Problems solved by technology

[0003] Traditional communication methods can meet the needs of daily command and dispatch, personnel positioning, and communication up and down the mine, but under landslide conditions, it will cause the problem of disconnection of wired communication lines and communication interruption

High-frequency wireless signals cannot effectively penetrate to form a communication link at the corner of the roadway, roadway collapse and blocked areas. In this case, the network base station path is also easily cut off. Therefore, the traditional mine communication system cannot meet the communication in emergency situations. Require

[0004] The traditional low-frequency electromagnetic wave ground-penetrating communication system uses the principle that low-frequency electromagnetic wave signals can penetrate large obstacles for communication. This communication method can realize ground-penetrating communication, but the communication frequency is low, and the signal decreases sharply with the increase of the distance between the transceivers. Effective voice information transmission cannot be realized in deep mines

In addition, the system antenna is large in size and is usually pre-installed in a fixed position in the mine. It is not suitable for portable portability by the staff, and is only suitable for use in emergency situations. It is difficult to apply to daily command and dispatch, personnel positioning, and communication between mines and mines.

Mine communication facilities cannot meet the needs of daily command and dispatch, personnel positioning, communication between mines and up and down the mine, and basic communication in emergency situations. If two sets of communication facilities are built, the cost investment will be relatively large
