The underground explosion-proof loudspeaker is connected with the broadcasting control main machine through a communication circuit, the scheduling table is connected with the scheduling main machine, one line of the scheduling main machine passes through an intrinsic safety telephone coupler for mining to be connected with the underground telephone for mining, another line of the scheduling main machine is connected with the ground communication telephone through a main distribution frame (MDF) directly, one line of the PC maintaining terminal is connected with the broadcasting control main machine through an Ethernet exchanger, and another line of the PC maintaining terminal is connected with the scheduling main machine through a recommended standard (RS) 232 interface. The scheduling broadcasting communication system not only is simple in structure, convenient and practical, but also can guarantee that the coal mine is convenient and accurate in scheduling, can improve broadcasting diversity and obtain an automatic scheduling communication function.
Description
Technical field
The utility model relates to a kind of broadcast communication system, and the colliery is with the scheduling broadcast communication system specifically.
Background technology
The colliery channel of communication is claimed mine communication system again, is Safety of Coal Mine Production scheduling, safe hedging and answers the slow important tool of first aid.Because coal production is mainly at underground job; Have that the work under bad environment working region is narrow and small, illumination difference, humidity, be corrosive; Unsafe factor mainly contains the threat of accidents such as water, fire, gas, top board more, the mobile many special factors such as big of personnel, equipment.See also have the characteristics that the multiplex (MUX) plants the associating continuous productive process in the down-hole from the production operation flow process, a lot of jumboes that have that this operation is regular are participated, and the transportation between the equipment, installation, debugging cooperate requirement very high, and message transmission must be in time, accurately.So safe, the needs produced of down-hole must both be satisfied with the scheduling broadcast communication system in the colliery, satisfy the demand of each side such as surface production, commander, management and people's life again.
The utility model content
The technical problem that the utility model will solve provides the colliery with the scheduling broadcast communication system, and is not only simple in structure, convenient and practical, and can guarantee that the colliery is accurately convenient when scheduling, strengthens the broadcasting diversity, realizes automatic dispatching communication function.
The utility model is that the technical scheme that the deficiency that solves the problems of the technologies described above adopts is: the colliery is with the scheduling broadcast communication system; Comprise broadcasting main control system, dispatching host machine, dispatching desk, PC maintenance terminal, downhole anti-explosion audio amplifier, the mining phone of ground communications phone and down-hole; The downhole anti-explosion audio amplifier is connected with the broadcasting main control system through communication line; Dispatching desk is connected with dispatching host machine; Behind the circuit process mine intrinsic safety telephone coupler of dispatching host machine, be connected through the mining phone in MDF distributing frame and down-hole, another circuit directly is connected with the ground communications phone through the MDF distributing frame; Link tester of PC maintenance terminal is crossed Ethernet switch and is connected with the broadcasting main control system, and another link tester is crossed the RS232 interface and is connected with dispatching host machine.
Described broadcasting main control system also is connected with microphone and power amplifier main frame.
The utility model beneficial effect is:
1, this system can independently broadcast a certain PC maintenance terminal and not influence other-end.Every zone can independently be broadcasted, and also can broadcast several zones simultaneously.
2, structure variation is accomplished a plurality of the connections of installing a telephone through coupler, strengthens the broadcasting diversity, realizes automatic dispatching communication function.
3, this system service radius is big, can connect a plurality of explosion-proof audio amplifiers and mining phone, and communication when ability is anxious reduces the disaster loss.
4, need not the system under colliery power supply, therefore, it is strong that system combats a natural disaster the change ability, when having a power failure, can not influence system's operate as normal.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Mark among the figure: 1, downhole anti-explosion audio amplifier, 2, the mining phone in down-hole, 3, the broadcasting main control system; 4, power amplifier main frame, 5, Ethernet switch, 6, the PC maintenance terminal; 7, microphone, 8, dispatching host machine, 9, the mine intrinsic safety telephone coupler; 10, MDF distributing frame, 11, dispatching desk, 12, the ground communications phone.
Embodiment
As shown in the figure; The colliery is with the scheduling broadcast communication system; Comprise broadcasting main control system 3, dispatching host machine 8, dispatching desk 11, PC maintenance terminal 6, downhole anti-explosion audio amplifier 1, the mining phone 2 of ground communications phone 12 and down-hole; Downhole anti-explosion audio amplifier 1 is connected with broadcasting main control system 3 through communication line, and dispatching desk 11 is connected with dispatching host machine 8, behind the circuit process mine intrinsic safety telephone coupler 9 of dispatching host machine 8; Be connected through the mining phone 2 in MDF distributing frame 10 and down-hole; Another circuit directly is connected with ground communications phone 12 through MDF distributing frame 10, and 6 one link testers of PC maintenance terminal are crossed Ethernet switch 5 and are connected with broadcasting main control system 3, and another link tester is crossed the RS232 interface and is connected with dispatching host machine 8.
Described broadcasting main control system 3 also is connected with microphone 7 and power amplifier main frame 4.
The broadcasting main control system is the control device of broadcasting, accomplishes terminal management, and management functions such as audio frequency controller are each multifunctional network terminal, and the terminal works door provides data handing-over service, and the real-time broadcasting control service of regularly playing is provided for each network terminal.
This system can independently broadcast a certain terminal and not influence other-end.
Every zone can independently be broadcasted, and also can broadcast several zones simultaneously.
Can all broadcast all terminals, hanging on 7 just can be directly to all carrying out urgent broadcast.
Digital broadcasting has all realized digitlization, networking from the transmission that is fabricated into of source of sound, and system signal noise ratio is high, can not produce noise in links such as processing, transmission, thereby can obtain reasonable tonequality, also can carry out stereo transmission.The down-hole EPA that can utilize part bargh to build up fully carries out the transmission of voice signal.
Downhole anti-explosion audio amplifier 1 is divided into explosion-proof main sound box and explosion-proof secondary audio amplifier, and explosion-proof secondary audio amplifier is connected with explosion-proof main sound box, has enlarged broadcasting area.
Can realize intelligent broadcast: Ethernet itself is exactly a cover bilateral network, on Ethernet, can easily realize the functions such as timing, addressing, grouping of intelligent broadcast through software.Under the situation that network speed allows, can realize multiplex broadcasting.Because audio file be mode with packet in transmission through network, so be easy to realize multiplex broadcasting, send to different terminal to different packets.Through the setting of Control Software, can realize that the same time is to the different different contents of zone broadcast.
System supports online speeches at different levels, need not special broadcasting center, only needs just can use microphone to carry out remote-page, meeting etc. through the PC maintenance terminal.
