Description
Technical field
The utility model relates to a kind of communication system, specifically, relates to a kind of multi-service wireless communication system for coal mine.
Background technology
In recent years, along with the propelling of country to " digitlization mine " work, communication condition, the automatization level in colliery were greatly improved.Wireless telecommunication system under the coal mine rises gradually, and the communication apparatus of down-hole develops into present widely used mobile communcations system by initial antiexplosion telephone, and user's portability mobile phone carries out the communication and the arrangement of work whenever and wherever possible.
The wireless telecommunications of Chu Xianing the earliest are " leakage current communication " (see figure 1)s, and it is the blank of wireless telecommunications.Its appearance allows " mobile call " to become reality, allows more colliery that more convenient communication tool has been arranged.
" leakage current communication " mainly is made up of three parts: 1. transmission medium (leaky cable, both-way trunk); 2. travelling carriage (hand-held set); 3. base-station.This communication modes mainly adopts leaky cable to carry out signal and covers, this cable is that (screen layer) offers a series of slotted eye or slot (seeing Fig. 2 and Fig. 3) on the coaxitron outer conductor of sparse braiding, the radio wave one edge cable of base-station emission is propagated to the tunnel depth, " sew " on one side in cable tunnel on every side, make the travelling carriage that is in the tunnel can receive this signal; The radio wave that the while travelling carriage sends is also given base-station through same path reverse transfer, so realized the two-way wireless communication of travelling carriage in base station and the tunnel.Cable inserts a both-way trunk at a certain distance, the loss when propagating in cable with compensating signal.This system only can can't carry out the personnel in the pit location as communication system at all.
This communication modes has following characteristics:
1. system architecture is simple, and equipment is single, is easy to safeguard;
2. signal coverage is easy to grasp, and leaky cable is laid part and is signal coverage;
3. bandwidth, but signal is disturbed easily;
4. signal is unsuitable for using at large and medium-sized mine with the deeply sharply decay in tunnel especially;
5. " bus type " signal covers, and " rolling off the production line " user is subject to factor affecting such as broken string, signal attenuation;
6. function is simple, function such as can't realize that the personnel in the pit locatees.
This shows that " leakage current communication " makes " wired " become " wireless " though changed the communication present situation in colliery; Make " landline telephone " become cellular phone.But limit because of himself system architecture, technical level, it can not become the main flow of wireless telecommunications.But its appearance is for certain basis has been established in the development of the radio communication in colliery.
At present at home, most popular is " down-hole Personal Handyphone System " system's (see figure 4), and this system transforms the PHS technology of ground maturation safely in addition is applied under the coal mine.It consists predominantly of five parts: 1. signal overlay device (base station); 2. Region control equipment (control cabinet); 3. transmission equipment (fiber optic); 4. power supply unit (power supply box); 5. mobile terminal device (mobile phone etc.).System adopts the honeycomb fashion networking mode, with the base station is to cover point, and adjacent a lot of base stations are an overlay area, a controller is set in this zone comes management of base station, and be responsible for carrying out the far-end power supply to the base station; The base station will be transferred to controller with the communication data of mobile phone, and controller is transferred to the ground switch with uniform data format.The power supply unification of all underground equipments is supplied with by a power supply, and promptly power supply is powered to controller, and controller utilizes communication line to power for all base stations.
" down-hole Personal Handyphone System " system has following characteristics:
1. system is huge, and it is many to hold the user, but cost is quite high, only is suitable for using at large and medium-sized mine;
2. honeycomb fashion networking is fit to tunnel complicated under the coal mine and distributes;
3. signal is not subject to disturb, and the stability of a system is good;
4. construction is complicated, to attendant's requirement height;
5. only can be used for speech communication, not be suitable for the expansion that the personnel in the pit such as locatees at additional function.
This system coal supply ore deposit brings great convenience, and the user need not to run out of several kilometers in abominable tunnel, down-hole and made a phone call; Situation that the people can not find can not appear looking for yet; More can not occurring has an accident all can't notify the situation in control room.At home, the wireless communications market that appears as the colliery of " down-hole Personal Handyphone System " system has been drawn back prelude.But, limited its high volume applications owing to its cost height, maintenance complexity, function face are narrow.On the other hand, it uses the frequency range of 1.9GHz, and the frequency range of communicating by letter with 3G overlaps, and can cause the interference of frequency, will clearly frequently move back net in 2011.Therefore, the development of wireless communication devices that is extended to of " down-hole Personal Handyphone System " system has been drawn back prelude.
More than two kinds of main wireless communication modes, can't satisfy the more and more higher technical need of coal mining enterprise at all.
