In the present embodiment, because the low-voltage network complicated network structure, topological branch are huge many, its characteristic of channel have impedance mismatch, time the feature such as change, frequency selective fading, noise be strong, broadband power line carrier communication unit is used in and has in the power information acquisition system communication channel of above feature, designed bandwidth carrier coupling device must meet the optimum performance requirement of signal transmission, namely in working band, the change of antidamping ability strong, anti-high-frequency resistance and anti-noise jamming ability strong.
As shown in Figure 3, when designing the signal coupling circuit of bandwidth carrier, based on Homeplug alliance standard, the signal passband chosen is 2 ~ 30MHz, centre frequency 16MHz.Low-voltage network topological structure and load ambiguity cause the line load impedance of different frequent points and line characteristic impedance to produce transient change, thus be difficult to mate with output impedance 50 Ω of carrier signal transmitter, cause multipath fading, this just requires that the effective attenuation of bandwidth carrier communication unit in working band designed is less than 8dB, attenuation outside a channel is greater than 40dB, to reduce the radiation effect of broadband carrier signal to civilian broadcast.For meeting high frequency matching principle, in free transmission range, require the effective attenuation plateau of signal and lower.In addition, for improving the interference rejection ability of power line carrier, PLC module 22, require that the coupling device of design can isolate the various noise synchronous with 50Hz power frequency.
The main principle of signal coupling circuit design to adapt to the Open network architecture of low-voltage network and complicated and diversified network characteristic thereof, meet the transmission requirement of high-frequency wideband signal, matched-phase characteristic and impedance operator, overcome disadvantageous electricity grid network characteristic and power line channel characteristic, consider convenience and the economy of practical application.
Low-voltage power line bandwidth carrier signal coupling circuit commonly uses capacitive coupling and inductive coupling two kinds of modes, and because of the transmission performance of inductive coupling, comparatively capacitive coupling is poor, and the signal coupling decay of generation is comparatively large, so only design capacitance coupled circuit herein.Carrier signal is injected on line of electric force by coupled circuit, by carrier wave transtation mission circuit, signal power is amplified again, utilizing carrier wave receiving circuit to be extracted by useful signal at the other end of line of electric force, for reducing the loss of signal on power circuit, needing improvement carrier transmitting-receiving circuit.
Capacitance coupling circuit is that main element carries out direct-coupled a kind of coupling device with coupling capacitance, and it by high frequency electrocardiography electrical network, also directly can receive high-frequency signal from line of electric force.As shown in Figure 3, one end of high frequency Y capacitance C10 connects low-voltage power line access point to capacitance coupling circuit, and the other end is connected with coupling transformer T1.C10 and resistance R2 form single order Hi-pass filter, and filtering is entrained in low-frequency noise signal in carrier signal and false signal, ensures that useful signal passes through, provides decay little as far as possible and linear amplitude-frequency, phase-frequency characteristic.If the RC filter cutoff frequency of R2 and C10 composition is 150KHz, by, calculate and get C10=0.0047, obtain R2=187 Ω.Coupling transformer T1 isolates strong, weak electricity, makes signal wire balance simultaneously.TVS is transient supression diode, prevents the strong jamming on electrical network and voltage surge, protection circuit device.R1 is the electric power generation unloading resistance of C10, usually gets 10M Ω.
Carrier wave transtation mission circuit as shown in Figure 4, the single tuning power amplifier that the high-frequency carrier signal of prime input is input to triode Q1 and peripheral component composition through signal carries out frequency-selecting power amplification, usually the output power of carrier signal can be improved tens times, then signal is coupled on line of electric force through tuning network.Circuit self-excitation can be effectively prevented, the concussion frequency of the fine-tuning tuning network of value of adjustment C3 at Q1 emitter access resistance R3.
As shown in Figure 5, the effect of the star-like diode mu balanced circuit in the left side of carrier wave receiving circuit suppresses fire, differential mode spiking between zero line and fire, common mode spiking between zero line and ground wire.For differential mode spiking, D2 and D3 forms a bi-directional voltage stabilizing pipe; For common mode spiking, this hub-and-spoke configuration is equivalent to two bi-directional voltage stabilizing pipes, can effectively boundary belt pass filter network from differential mode, common mode interference.R4 and R7 is the isolation resistance of series resonant network, the output impedance of the R5 analog electrical line of force, and R7 simulates coupled circuit output impedance.R5, R7 all get 50 Ω to meet impedance matching.On the right side of bandpass filtering network, voltage stabilizing diode D4, D5 form double limiting circuit, prevent signal amplitude too large damage follow-up signal decoding circuit.
In the present embodiment, by main control module 21, the electric power data of handheld device collection is carried out the message corresponding with power line carrier, PLC, and by power line carrier, PLC, message is sent to collection main website, and main control module 21 controls power management module 23 handheld device and charges, solve in current information collecting device, the data collected transfer data to analysis platform by wired or wireless mode, need for Equipments Setting dedicated line or add additional communication device, that caused is unfavorable for the integrated of system, and transmission line is easily subject to extraneous interference and affects the technical matters of transmission quality.
