Sampling controller for power line carrier data transmission system

The utility model relates to a collecting and controlling device for a power line carrier data transmission system. The purposes are to collect a plurality of bits of data and switch signals and transmit a plurality of bits of control signals to control an executive mechanism to rationally and effectively work. The utility model is mainly composed of a frequency modulating circuit, a frequency decoding circuit, an amplitude limit amplifying circuit, a power amplifying circuit, and an A/D converting circuit, a coding and decoding circuit, an amplifying shaping circuit and a control logic circuit which are composed of integrated pieces IC 1. The utility model has the advantages of combining coding and decoding, 8 bits of data and a plurality of transmitting bits. The utility model achieves integration of data acquisition / processing and the control of the executive mechanism with strong versatility, and enhances the technique performance of the whole system.
