The invention relates to an underwater signal collection wireless communication device for lead fish current surveying and a communication method thereof, and belongs to the technical field of hydrological communication. The underwater signal collection wireless communication device comprises a current meter and an antenna. A water surface switch of a lead fish detects whether the lead fish enterwater or not and determines the work state of the current meter; the current meter collects the water flow velocity of a single point; a bottom touch switch of the lead fish detects whether the lead fish reaches the bottom or not; a signal barrel is fixed on the gravity center of the lead fish, the circuit in the signal barrel packages the collected lead fish water entering information, flow velocity data, and lead fish bottom reaching information to obtain data packages, the data packages are stored in the circuit in the signal barrel; and then the data is emitted to an upper computer throughan LoRa circuit module in the signal barrel, a radio frequency line, and the antenna. The wireless communication device is used for communication of hydrological lead fish current surveying. The datais transmitted through a LoRa wireless duplex communication method. The upper computer calculates and analyzes the received data to obtain real-time data of water flow velocity.
Description
technical field [0001] The invention relates to an underwater signal acquisition wireless communication device and a communication method for lead fish flow measurement, belonging to the technical field of hydrological communication. Background technique [0002] Underwater communication method is one of the important branches of hydrographic communication technology, and it is an important part of underwater monitoring, underwater development and underwater military struggle. In order to better prevent floods and reduce disasters, compete for water resources and enhance underwater combat capabilities, underwater communication technology has been paid more and more attention. Underwater communication can be divided into two types: underwater wired communication and underwater wireless communication. [0003] Underwater wired communication can be realized by laying underwater optical cables and underwater cables. Although underwater wired communication has the advantages of...
