Inland waterway real-time monitoring system based on optical fiber acoustic sensor array

The invention discloses an inland waterway real-time monitoring system based on an optical fiber acoustic sensor array. The inland waterway real-time monitoring system comprises the optical fiber acoustic sensor array, a photovoltaic conversion module and a signal processing module. The optical fiber acoustic sensor array comprises a plurality of optical fiber acoustic sensor units and communication optical cables. Sound field signals of ships in the waterway are received by the acoustic sensor units, converted into optical signals, transmitted to a bank through the communication optical cables and transmitted to a computer or a signal processing control panel after converted into electrical signals. The signal processing module calculates output signals, allowing indicates such as flow, position, course, speed of the ship in the inland waterway to be monitored real time. The inland waterway real-time monitoring system is an automatic inland waterway monitoring system, active, wide is application range, high in interference resistance and affected by weather conditions, and all-weather real-time monitoring of the inland waterway is achieved.
