Power load microcomputer external guidance system research and realization
This article borrows the assistant engineer the frequency communication ,has designed one kind to the power load external guidance system. This is one kind is effective also has the development very much the control method. This technology artificial short-circuits take the electrical network creates the electrical network waveform distortion as a principle. According to agreement code rule, uses three item of wheels to send the system, leads using the MCS-51 monolithic integrated circuit control crystal hydration passes, creates the power line short-circuiting. Thus obtains the expectation the voltage distortion. And spreads over this distortion signal the entire electrical network, under causes to be located the good end receiver to be easy to receive the order. In future will defer to the order to the nearby regions implementation control. Has realized the power load remote control function.
