As shown in fig. 6, it is the power line carrier module and interface circuit that power line carrier, PLC function is provided for system.In figure Carrier chip is connected by SCL, SDA and single-chip microcomputer, its peripheral interface circuit include power amplification circuit, filtering shaping circuit, Resonance circuit and secondary filtering circuit.Power amplification circuit is for carrier (boc) modulated signals caused by carrier chip are carried out into power It is coupled to after amplification on power line.After carrier wave function is enabled, carrier signal is exported by PSK_out, and waveform is 0-5V changes Square wave, include abundant harmonic wave；After push-pull circuit carries out power amplification, the square-wave signals of PSK_out points passes through after being exaggerated After inductance L1, electric capacity C3 complete shaping filter, then it is coupled on low-voltage power line by coupling coil T, bilateral diode D7 rises Protective effect.D3, D4 play spike that is clamped, absorbing on low-voltage power line and disturbed in circuit.In Fig. 3 reception loop, R3 can effective attenuation by absorption when receiving local strong transmission signal；Inductance L2, electric capacity C6 form shunt-resonant circuit, resonance with Centre frequency designs for 120KHz, completes the bandpass filtering to useful signal；Good frequency-selective circuit can effectively improve carrier wave Receiving sensitivity.Diode D5, D6 effect are to clamp down on the current potential of reception signal in ± 0.7V.Reception signal passes through electric capacity C4 After be incorporated into chip internal and carry out Frequency mixing processing, SIGIN is moved to 2.5V ± 0.7V after being pulled up by inside, in favor of follow-up place Reason.In the post processing circuitry of carrier signal, the carrier signal received after parallel resonance enters chip through SIGIN pin.Due to pottery Porcelain filter passbands can only be near intermediate frequency, so chip internal is by the 120KHz signals received and internal 600KHz sheets The signal that shakes is mixed, and obtains the difference frequency signal of 80KHz intermediate-frequency bandwidths.Mixed frequency signal is input to ceramic filter by FLTI pin Input pin, the FLTO pin for sending chip after ceramic filter filtering back to again carry out internal limited range enlargement.Then by the hardware in chip De-spreading circuit carries out the reduction of valid data；Data bit is latched into data pins after the completion of data despreading, while produces synchronization Signal HEAD；
Power amplification circuit is to be coupled to electricity after carrier (boc) modulated signals caused by carrier chip are carried out into power amplification In the line of force.After carrier wave function is enabled, carrier signal is exported by delivery outlet PSK_out, and waveform is the square wave of 0-5V changes, comprising Abundant harmonic wave；After push-pull circuit carries out power amplification, the square-wave signal of delivery outlet PSK_out points is exaggerated, in circuit D3, D4, which play spike that is clamped, absorbing on low-voltage power line, to be disturbed.The size of carrier wave transmission power and VHH power supply amplitudes Just, source current offer ability is closely related, and power supply amplitude, increase power are improved in certain limit, can effectively be added Big transmission power, so as to extending communication distance.It is dirty to the harmonic wave of power network to reduce because the signal waveform after amplification is rich in harmonic wave Dye, need to be filtered shaping.After inductance L1, electric capacity C3 complete shaping filter in circuit, then low pressure is coupled to by coupling coil T On power line, bilateral diode D7 shields.
It is the communicator program processing flow diagram of system as shown in Figure 7.Judge carrier communication interrupt request.Work as power carrier When communication is in reception state, after carrier communication control unit solution expands 1bit data, generation is once interrupted.Adopted first during reception Synchronizing frame head 0X09,0XAF of communication are received with 16bits receptions window, 1bit sliding types, after frame head receives successfully, after Continuous data are intercepted in the way of every mono- byte of 8bits, the valid data transmitted；In receive process, by relevant Communication protocol enters row address differentiation, length receives, verification calculates.Address identical module is carried out to the data for meeting communication protocol Response, after be transferred to transmission state.When carrier communication, which is in, sends state.Calling party for carrier communication sends order or received The response of side.After carrier communication control unit has sent 1bit spread spectrum data, automatically generate and once interrupt, it is allowed to lower 1bit numbers According to transmission.According to capture and synchronizing process needs, it is first sent to few 40bits complete " 1 "；Then synchronization frame is sent by bit Head 0X09,0XAF；Mailing address, data length, data volume, verification are sent by bit according to the relevant communication protocol of user afterwards Etc. byte.After data are all sent completely, carrier module can be transferred to reception state.But it is last for ensuring data to be sent Bit is sent successfully, it is necessary to after wait until to send an interrupt to after having sent last 1bit data next time, can just change load Ripple sends state to reception state.Before total data is not sent completely by carrier wave transmission, CPU must be in time to PLM_RST register writes Enter " A2H ", make counter resets, the incoming carrier in advance that avoids automatically reseting receives state.
