Abstract
The utility model discloses a network extender, and belongs to the field of electronic information technology. The network extender comprises a voice separation module, a rectification feedback module, a discrete multi-tone modulation module and a data processing module, wherein the voice separation module, the rectification feedback module, the discrete multi-tone modulation module and the data processing module are sequentially in electric connection. The voice separation module is connected with a telephone line interface, and the data processing module is connected with an RJ 45 connector and an RS 485 interface. By means of the network extender, the technical effect that in coal mine communication, although transmission modes and transmission media are diverse, optical cable networks and electric cable networks can be expanded seamlessly can be achieved, and the network extender can be widely used in information transmission in coal mines.
Description
Technical field
The utility model relates to electronic information technical field, relates in particular to a kind of network extender.
Background technology
At present, most domestic colliery communication cable laying area in early stage is less, new work face optical cable can't lay, original Ethernet transmission can't be satisfied the long-distance transmissions of two-forty, transmission means is single, and transmission medium is single, can't realize the seamless expansion of fiber cable network and cable system, so that new work zone and periphery can't be realized the wireless video communication, these conditions have seriously fettered the colliery communication, the transmission means variation, the transmission medium variation, the communication apparatus that can make fiber cable network and the seamless expansion of cable system is that the colliery communication is necessary.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of network extender is provided, to solve transmission means and transmission medium variation in the communication of colliery, can makes the technical problem of fiber cable network and the seamless expansion of cable system.
For solving the problems of the technologies described above, the technical solution of the utility model is: the network extender, comprise the speech Separation module, rectification feedback module, Discrete multi-tone modulation module and the processing data information module that are electrically connected successively, described speech Separation module is connected with telephone line interface, and described processing data information module is connected with RJ45 interface and RS485 interface.
As a kind of improvement, the chip of described processing data information module is the IP175D chip.
After having adopted technique scheme, the beneficial effects of the utility model are: owing to having designed the speech Separation module that is electrically connected successively, the rectification feedback module, Discrete multi-tone modulation module and processing data information module, from the RS485 protocol data of Double-strand transmission and deliver to the processing data information module from the IP protocol data of fiber optical transceiver RJ45 port after by protocol conversion and carry out route switching, basis protocol mode separately transmitted by RS485 interface or RJ45 interface again after exchange message was finished, incorporate the wireless video communication system, realize the seamless expansion of fiber cable network and cable system, and realized transmission means and transmission medium variation.
Because the processing data information module adopts the IP175D chip, IP175D is high speed routing processing data information exchange chip, and is one of chip commonly used at present, draw materials extensively, with low cost, and the medium medium do not had special requirement, common UTP cable (category-5 cable) all is enough to be competent at.
Description of drawings
Accompanying drawing is the theory diagram of the utility model embodiment;
Among the figure: 1, speech Separation module, 2, the rectification feedback module, 3, the Discrete multi-tone modulation module, 4, the processing data information module, 5, telephone line interface, 6, the RJ45 interface, 7, the RS485 interface.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in drawings, a kind of network extender, comprise the speech Separation module 1, rectification feedback module 2, Discrete multi-tone modulation module 3 and the processing data information module 4 that are electrically connected successively, speech Separation module 1 is connected with telephone line interface 5, usually, telephone line interface 5 is the RJ11 interface, and processing data information module 4 is connected with RJ45 interface and RS485 interface, and the chip of processing data information module 4 is preferably comparatively common IP175D chip.Like this, from the RS485 protocol data of Double-strand transmission and deliver to processing data information module 4 from the IP protocol data of fiber optical transceiver RJ45 port after by protocol conversion and carry out route switching, basis protocol mode separately transmitted by RS485 interface 7 or RJ45 interface 6 again after exchange message was finished, incorporate the wireless video communication system, realized the seamless expansion of fiber cable network and cable system, and the medium medium is not had special requirement, and common UTP cable (category-5 cable) all is enough to be competent at.
The utility model is not limited to above-mentioned concrete execution mode, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection range of the present utility model.
