Under the promotion of national integration of three networks development strategy, China's radio and television services have entered a new developing period, and the bidirectional rebuilding of CHINA RFTCOM Co Ltd is by imperative.On January 13rd, 2010, State Council holds standing meeting, determine to accelerate to advance telecommunications network, broadcasting and television network and the Internet integration of three networks, under the promotion of national integration of three networks development strategy, China's radio and television services have entered a new developing period, take two-way, interactive, cross-domain, intercommunication, multi-service, credible, can manage, development industry situation that the controlled broadcasting and television network of new generation as feature will innovation broadcasting and TV.
The General Office of the State Council has sent " about the notice of printing and distributing first integration of three networks model regions (city) list " on June 30th, 2010, first integration of three networks model regions (city) list is come out of the stove, comprise Beijing, Daliang City of Liaoning Province, Harbin, Heilongjiang Province, Shanghai City, Nanjing, Hangzhou, Zhejiang province city, Xiamen City, Fujian Province, Qingdao of Shandong province, Wuhan City, Hubei Province, area, governor's strain pool, Hunan, Shenzhen City, Guangdong Province and Sichuan Province's Mianyang City, this indicates that integration of three networks pilot work formally starts.
Along with the integration of three networks, 3Tnet, IP kernel heart net, the maturation of fiber optic network technology, fiber entering household, domestic consumer broadband increases substantially, the problems such as fiber entering household difficulty, indoor networking difficulty become increasingly conspicuous, thereby have affected to a great extent installation personnel's operating efficiency and user's impression.
Utility model content
The purpose of this utility model is to overcome the problems such as current fiber entering household difficulty, indoor networking difficulty and becomes increasingly conspicuous, thereby affect to a great extent the defect of installation personnel's operating efficiency and user's impression, provide one not only simple in structure, and with low cost, can also plug and play and do not need assembling wiring, thus user-friendly power line modem.
The object of utility model is achieved through the following technical solutions:
A kind of power line modem, comprises master chip, is connected with respectively crystal oscillator, attaching plug and transformer on described master chip; Described transformer is also connected with attaching plug; On described master chip, be also connected with network interface by exchange chip.
Further, described crystal oscillator is quartz-crystal resonator.
Further, between described master chip and attaching plug, be also connected with filter.
Further, on described master chip, be also connected with storage chip.
In order to satisfy the demand, described storage chip is FLASH chip.
In order to satisfy the demand better, the model of described master chip is BCM60321.
In order to realize better the utility model, the model of described exchange chip is BCM5241.
In order to ensure effect, described network interface is RJ45 interface.
The utility model is compared compared with prior art, has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and with low cost, also can plug and play, when use, only external network signal need to be accessed by network interface of the present utility model, then after signal being processed by exchange chip of the present utility model and master chip, output on power line and carry out indoor transmission by attaching plug, then using another power line modem of the present utility model signal on power line can be outputed on user's use equipment; User uses the utility model without any software and driver is installed, do not need wiring, easy to connect and wide coverage, transmission quality is high, speed is fast, bandwidth is stable, can make up the deficiency of WIFI transmission and traditional wiring transmission, thereby is more convenient for user's use.
(2) crystal oscillator of the present utility model is quartz-crystal resonator, is convenient to the clock pulse signal of the standard that produces.
(3) between master chip of the present utility model and attaching plug, be also connected with filter, be convenient to signal transmission to carry out filtering processing, make the signal of output more simple.
(4) on master chip of the present utility model, be also connected with storage chip, be convenient to storing data information.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail:
Embodiment
As shown in Figure 1, power line modem of the present utility model, comprises master chip, and the model of the master chip using in the present embodiment is BCM60321, and the physical layer rate of this master chip is 200Mbps.On described master chip, be also connected with network interface by exchange chip, the signal of the described exchange chip that the utility model uses is BCM5241.Described network interface is RJ45 interface, for accessing external network signal or network signal being outputed to user's local side apparatus.
