Simulation method for integration of transmission and positioning of underwater optical communication

The invention discloses a simulation method for integration of underwater optical communication, transmission and positioning. The simulation method comprises the following steps: sending a signal to a surrounding receiving end through a light emitting diode of a sending end; when the receiving end receives the signal from the sending end, the receiving end sends a light intensity signal to the sending end; receiving a light intensity signal through a prism of the transmitting end, calculating corresponding light intensity information through the light intensity signal, calculating the position of the underwater node relative to the receiving end according to the light intensity information, and positioning the underwater node; and S2, sending a confirmation signal to the receiving end through the sending end, judging whether handshake is completed or not according to the confirmation signal, if so, establishing a link between the sending end and the receiving end, and performing maintenance through optical p
