Abstract

The invention provides a signal receiving device, a control method of the signal receiving device and an optical communication system, and the control method of the signal receiving device comprises the steps: obtaining a current first control voltage of an optical signal intensity adjustment device, a current second control voltage of an optical detector, and a current AD sampling value and a target AD sampling value of an AD sampling device; calculating initial incident light power according to the current AD sampling value, the current first control voltage and the current second control voltage; calculating a target first control voltage and a target second control voltage according to the target AD sampling value and the initial incident light power; and respectively updating the current first control voltage and the current second control voltage based on the target first control voltage and the target second control voltage. By implementing the invention, the self-adaptive control and optimization of the received signal are realized, and the transmission performance of an optical communication system and the stability and reliability of communication are improved.

Description

technical field [0001] The invention relates to the field of underwater wireless optical communication, in particular to a signal receiving device, a control method of the signal receiving device and an optical communication system. Background technique [0002] Underwater wireless optical communication is an underwater high-speed communication method. This communication method requires the transmitting end to modulate the data information into an optical signal, and the detector at the receiving end detects the optical signal, and converts the optical signal carried according to the change of light intensity into Data information, to complete the reception, detection and demodulation of data information. [0003] However, due to the complex underwater channel conditions, affected by factors such as platform vibration, water flow, and scattering particles, the transmitter and receiver cannot maintain a stable position, the attenuation of the wireless optical link is constant...
