Abstract

The invention discloses a hydrological two-channel underwater communication system. The system comprises an overwater unit and an underwater unit, and is characterized in that the overwater unit comprises a radio receiving module, an ultrasonic wave receiving probe, a receiving drive and signal demodulation module, a water surface microprogram control unit (MCU) module and a radio forwarding module. The underwater unit comprises a radio transmitting module, an ultrasonic wave transmitting probe, a transmitting probe drive module, an underwater MCU module and a signal acquisition module. The underwater communication system communicates through two channels including the underwater ultrasonic wave and the radio, realizes medium and short distances of underwater communication while having the cost of civil and commercial grades of equipment, solves the problems of instability and unreliability of medium and short distances of communication, and keeps medium and short distances of underwater communication continuous and highly reliable.

Description

technical field [0001] The invention relates to the field of underwater communication, in particular to a hydrological dual-channel underwater communication system suitable for medium and short distances. Background technique [0002] At present, most of the communication technologies used in the hydrological industry are based on electromagnetic waves, but electromagnetic waves have the characteristics of large attenuation, short transmission distance, and low efficiency underwater, which makes the application of these systems unstable and reliable. Although the sonar communication technology of the military industry The underwater communication distance is long, but the cost is extremely high, and it is not suitable for underwater medium and short-distance communication. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the above-mentioned traditional underwater communication methods, provide a highly reliable hydrolo...
