Accompanying drawing explanation
For content of the present utility model is more likely to be clearly understood, below the specific embodiment by reference to the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the structured flowchart of Internet of Things system of connections of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail:
See Fig. 1, a kind of Internet of Things system of connections, comprise: some router of internet of things, described router of internet of things comprises: wireless routing unit, the microprocessor module that is suitable for receiving radio data being connected with this wireless routing unit, this microprocessor module is suitable for providing Homeplug AV agreement and carries out OFDM(is orthogonal frequency division multiplexi) modulating/demodulating, the DA module being connected with the digital signal transmitting terminal of described microprocessor module, the analog signal output of this DA module is connected for the coupling module that the analog signal of its output is coupled to power line and is transferred to corresponding router of internet of things with one, described coupling module is also connected with an AD module, and the signal that is suitable for corresponding router of internet of things to transmit by power line receives to described AD module, and this AD module is connected with the digital signal reception end of described microprocessor module.
Wherein, the implication of Homeplug AV agreement is, the physical layer of Homeplug AV is used OFDM modulation system, it be by information code element to be sent by serial to parallel conversion, changing down, thus increase code-element period, the impact of disturbing to weaken multipath.It uses Cyclic Prefix (CP) as protection interval simultaneously, greatly reduces and has even eliminated intersymbol interference, and guaranteed the orthogonality of each interchannel, thereby greatly reduced interchannel interference.In OFDM, each subcarrier spectrum has 1/2 overlapping quadrature, has improved like this availability of frequency spectrum of OFDM modulation system.At receiving terminal, by correlation demodulation technology, isolate each carrier wave, eliminate the impact of intersymbol interference simultaneously.
Homeplug AV is used 917 subcarriers in 2-28MHz frequency range; Power spectral density is able to programme, to meet the frequency control of country variant; Each subcarrier can carry out separately BPSK, QPSK, 8QAM, 16QAM, 64QAM, 256QAM and 1024QAM modulation; Adopt Turbo FEC error checking; Physical layer line speed reaches 200Mbps, and payload is 150Mbps, approaches the message capacity of power line channel.
Described microprocessor module can adopt FPGA or DSP to realize OFDM modulating/demodulating.
In use, at least two router of internet of things cooperatings, one is set as active router, one is set as from router, described two router of internet of things are plugged in respectively in the supply socket in two rooms, the network signal that main frame receives Ethernet transfers in power line by DA module and coupling module, another room from router, by coupling module and AD module, receive the corresponding signal power line, and the signal that it is received carries out wireless-modulated with in covering chamber; And between router and active router, by corresponding coupling module, power line, carry out reception and the transmission of signal.
According to prior art, the frequency band range of power line network at 1.6MHZ between 30MHZ.When sending, utilize OFDM modulation technique that user data is modulated, then on power line, transmit, at receiving terminal, first through overcoupled circuits, modulation signal is leached, through demodulation, just can obtain former signal of communication, its traffic rate does not coexist 4.5M between 200M according to concrete equipment at present.
