Description
Technical field
The utility model relates to a kind of mining Mobile Leakage Communication System Used, refers to especially a kind of mining Mobile Leakage Communication System Used of transmitting by digital signal.
Background technology
The idealized model of underground communica tion is the downhole wireless mobile communication system, but because the particularity of subsurface environment, radio wave is propagated in the tunnel and is run into very large difficulty, underground mobile communication only well addresses this problem by means of wired ability, namely uses coaxial leaky cable to carry out the information transmission as communication media.
Present domestic Mobile Leakage Communication System Used is analog communication system, the simulation Mobile Leakage Communication System Used easily be disturbed, produce during relay transmission noise stack, operating efficiency lower, can't the transmission of data, individual system can't realize the shortcomings such as multichannel networking, power system capacity be little, can not satisfy the information system requirement of mine construction.
The utility model content
The utility model aims to provide and a kind ofly can carry out voice call and can carry out again that transfer of data and antijamming capability are strong, the mining digital Mobile Leakage Communication System Used of long transmission distance.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
Mining digital Mobile Leakage Communication System Used, comprise the floor control machine and with the digital handheld machine of floor control machine communication, the floor control machine connects the data message that sends in order to analyzing and processing floor control machine by the networking, therefrom obtain the information such as source address, destination address, ID, time, according to the functional requirement of equipment show, the number base platform of voice suggestion, forwarding and storage; The signal output part of number base platform is connected with repeater, and the signal output part of repeater connects distributor.
Mining digital Mobile Leakage Communication System Used, described divider signal output is connected with for digital signal reception and transmission every a segment distance, eliminates the gradually digit regeneration repeater of cumulative noise of repeater.
Mining digital Mobile Leakage Communication System Used, described number base platform, hardware components comprise rf board, channel board and three parts of master control borad; Rf board is comprised of the radio station radio frequency unit; The digital-to-analogue conversion of channel board modulus, DSP and coprocessor form, three interactive connections of parts; Master control borad is comprised of main control unit, memory cell, audio frequency input-output unit, connection serial ports and display unit, and each parts all is connected with main control unit is interactive.
Mining digital Mobile Leakage Communication System Used, described number base platform adopts serial ports or Ethernet interface to be connected with the floor control machine, can receive the various data that the floor control machine issues and be transmitted to the digital handheld machine, can receive the various Data Concurrents that the digital handheld machine uploads and give the floor control machine.
Mining digital Mobile Leakage Communication System Used, described number base platform display unit adopts the OLED display screen.
Advantage of the present utility model is:
(1) mining digital Mobile Leakage Communication System Used of the present utility model adopts digital radio station spreading digital signal, and antijamming capability is strong, and signal is not easy to lose.Use tdma, can become four time slots to a channel distribution, formed four Traffic Channels, do not interfere with each other between the Traffic Channel, greatly improved the utilization ratio of frequency.
(2) adopt digital signal to transmit, can realize that voice-and-data transmits simultaneously.
(3) in the leaky feeder communication network, use the digit regeneration repeater can remove noise, greatly improved communication quality, prolonged communication distance.
(4) the number base platform is furnished with the OLED display screen, can receive the information of ringing a bell that the digital handheld machine sends and dynamically is presented on the OLED screen; The digital handheld machine is furnished with the OLED display screen, and the short message data that ground can be assigned is presented on the screen.

Embodiment
As shown in Figure 1, the utility model provides a kind of mining digital Mobile Leakage Communication System Used, comprise that floor control machine 1, number base platform 2, digital handheld machine 6, digit regeneration repeater 4, repeater 3, distributor 5, adaptation 7 form, and can carry out transfer of data and voice call.Number base platform 2, digital handheld machine 6, digit regeneration repeater 4 have digital received and transmitting element separately, are used for receiving and sending digital signal.When sewing network organizing, every about 5 kilometers, arrange a digital regenerative repeater 4, can become gradually large noise and eliminate analog repeater 3 is cumulative.
Described number base platform 2, hardware components comprise rf board, channel board and three parts of master control borad; Rf board is comprised of radio station radio frequency unit 17; Channel board is comprised of modulus digital-to-analogue conversion 16, DSP 15 and coprocessor 14, three interactive connections of parts; Master control borad has main control unit 12, memory cell 9, audio frequency input-output unit 13, connects serial ports 10 and Ethernet interface 11, and display unit 8 compositions, and display unit 8 adopts the OLED display screens, and each parts all is connected with main control unit 12 interactive modes.Groundwork is the data message that analyzing and processing digital radio station or floor control machine send over, and therefrom obtains the information such as source address, destination address, ID, time, according to the functional requirement of equipment show, the operation such as voice suggestion, forwarding and storage.
Digit regeneration repeater 4 has effectively solved the noise stack problem of analog repeater in the system as the network digital trunking, and the communication distance of system can be provided greatly, improves the speech quality of system.Whole device hardware circuit is divided into the downstream signal processing and upward signal is processed the two large divisions, the downstream signal processing section is to process the band downlink signal that the number base platform emits, and the upward signal processing section is to process the uplink band signal that the digital handheld machine emits.The processing method full symmetric of two parts is identical.Handling process is first input signal to be carried out demodulation by filter, convert original digital information to carrying out AD, allow and rear original digital information is carried out modulation output after the DA conversion, finish like this screening to useful data information, remove interference signal, realize the regeneration of signal.
