Photoelectric conversion circuit and realizing method thereof based on 1553B bus

The invention relates to a photoelectric conversion n circuit and a realizing method thereof based on a 1553B bus, the circuit is composed of an isolation transformer, a sender and a receiver, wherein, the sender is composed of an interface driving unit A, a dual/single end signal converting unit, a control signal generating unit and a photoelectric conversion unit, the receiver is composed of a photoelectric conversion unit, a dual/single end signal converting unit and an interface driving unit B, an electric signal is converted into a photo signal to transmit through the photoelectric conversion circuit of the 1553B bus, the zero level signal status and the no signal status of a 1553B bus signal can be effectively distinguished by the photoelectric conversion circuit and the signal can be accurately transmitted between the 1553B bus, thereby realizing the remote transmission of the 1553B bus signal, moreover, the photo signal has the characteristic of anti-electromagnetic interference, thereby increasing the anti-interference capability of 1553B signal transmission.
