The EOC terminal comprises an EOC chipset, an Ethernet exchange chip, a WIFI module, a duplexer and an analog front-end circuit, wherein the duplexer is connected with a coaxial cable and used for receiving a mixed signal of cable television and network data, separating a network data signal from the mixed signal and transferring the network data signal to the analog front-end circuit, the analog front-end circuit carries out preprocessing on the network data and transmits the preprocessed network data to the EOC chipset, the EOC chipset is connected with the Ethernet exchange chip, and the Ethernet exchange chip is connected with a plurality of RJ45 interfaces and with the WIFI module. According to embodiments in the utility model, the WIFI module and the EOC chipset are combined together, the resource of the coaxial cable is fully utilized, so an Ethernet signal and a wireless WIFI function can be provided besides a television signal; wiring structure of a local area network is greatly improved and meets requirements of integration of three networks by the State Administration of Radio Film and Television in China.
Description
Technical field
The utility model relates to the EOC technical field, is specifically related to a kind of EOC terminal of the WIFI of having function.
Background technology
At present, cable network is all take coaxial cable as main.Chinese broadcasting and TV general bureau to the integration of three networks to the transformation at family also take coaxial cable as main, optical fiber direct is received then somewhat expensive of family, high cost also is unfavorable for safeguarding simultaneously.
EOC(Ethernet over COAX ether data communication device is crossed coaxial cable transmission) transmission technology, be based on the characteristics of cable TV coaxial net and the Ethernet connecting system that designs.Utilized cable TV signal to use the high-end frequency of 45～860MHZ, the base-band data signal of Ethernet uses the low side frequency signal of 2～30MHZ, so two kinds of signals can transmit in same cable and be independent of each other.The base-band data signal of Ethernet and TV signal are fed on the distribution cable (coaxial cable) of former television network by mixer, deliver to together the EOC terminal.Then the EOC terminal is separated TV signal with base-band data signal, and TV signal sends to television set, and base-band data signal is sent to computer.
In the prior art, based on the WLAN (wireless local area network) of EOC terminal, need to utilize copper twisted pairs to consist of LAN.The shortcoming of the local area network (LAN) construction method that this is traditional is, netting twine wiring inconvenience, and the malfunction elimination difficulty, its autgmentability is relatively poor etc., has therefore greatly limited applying of EOC terminal.
The utility model content
The utility model provides a kind of EOC terminal of the WIFI of having function, can address the above problem.
The utility model provides a kind of EOC terminal of the WIFI of having function, comprise the EOC chipset, Ethernet switching chip, the WIFI module, duplexer and analog front circuit, duplexer connecting coaxial cable wherein, receive the mixed signal of cable TV and network data, and the network data signals that separates wherein transfers to analog front circuit, described AFE (analog front end) road carries out described network data to transfer to the EOC chipset after the pre-process, described EOC chipset connects Ethernet switching chip, Ethernet switching chip connects a plurality of RJ45 interfaces, and described Ethernet switching chip also connects described WIFI module.
Preferably, be connected by a keyset between described Ethernet switching chip and the described WIFI module, one power amplifier is set on the described keyset, and the input of described power amplifier connects Ethernet switching chip, and the output of described power amplifier connects the WIFI module.
Preferably, also be provided with a switch on the described keyset, the work of described switch control keyset opens and closes.
Technique scheme can be found out, because the utility model embodiment adopts WIFI module and the mode that the EOC chipset combines, takes full advantage of the coaxial cable resource, and ethernet signal and wireless WIFI function can also be provided except TV signal is provided.Greatly improve the wire structures of local area network (LAN), also met the requirement of the integration of three networks of General Bureau of Radio, Film and Television simultaneously.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic block circuit diagram among the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtain under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
The utility model embodiment provides a kind of EOC terminal of the WIFI of having function, as shown in Figure 1, comprise the EOC chipset, Ethernet switching chip, the WIFI module, duplexer and analog front circuit, duplexer connecting coaxial cable wherein, receive the mixed signal of cable TV and network data, and the network data signals that separates wherein transfers to analog front circuit, described AFE (analog front end) road carries out described network data to transfer to the EOC chipset after the pre-process, described EOC chipset connects Ethernet switching chip, Ethernet switching chip connects a plurality of RJ45 interfaces, and described Ethernet switching chip also connects described WIFI module.
In order to control the transmission of strengthening wireless signal, be connected by a keyset between Ethernet switching chip described in the utility model embodiment and the described WIFI module, one power amplifier is set on the described keyset, the input of described power amplifier connects Ethernet switching chip, and the output of described power amplifier connects the WIFI module.Be understandable that this keyset can adopt the mode of simple and easy pcb board, power amplifier is printed on the pcb board, the input of power amplifier and output have all pre-established Wiring port, need to be to EOC termination extension WIFI function if need, then the WIFI module is connected on the Ethernet switching chip by keyset and gets final product, add this structure of keyset, can allow the expansion of WIFI module convenient, and easy-to-connect.Power supply on the keyset is supplied with the power supply that can directly use the EOC terminal, also can independently use external power supply.
Because the WIFI module needs certain energy consumption, and the user also just just opens the WIFI module in due course, can prevent that to a certain extent other people from " rubbing net ", prevents information leakage.Therefore the utility model embodiment also is provided with a switch on keyset, and the work of described switch control keyset opens and closes.Those skilled in the art can be known: described switch can be connected between power supply and the power amplifier, thereby whether the work of power ratio control amplifier, in case power amplifier quits work, the signalling channel that then transfers to the WIFI module by the Ethernet conversion chip then is in off-state, so the WIFI module does not receive the signal of Ethernet conversion chip.
More than the EOC terminal of a kind of WIFI of having function that the utility model embodiment is provided be described in detail, used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand core concept of the present utility model; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
