Embodiment Construction
[0026] The invention provides an underwater acoustic remote control method, the basic idea of which is: the remote control party sends an underwater acoustic remote control FM signal, and the underwater acoustic remote control FM signal is composed of multiple single-frequency signals in a set sequence; The party receives the underwater acoustic remote control FM signal, detects the size and arrangement and combination order of each single-frequency signal contained in the underwater acoustic remote control FM signal, and compares them with the preset conditions, and the signal size and arrangement and combination order all meet the conditions Then the output value changes to act as a signal instruction.
[0027] Through the study of the optimal propagation frequency of underwater signals, it can be designed that the underwater acoustic remote control FM signal consists of three frequency bands of 9000Hz, 12000Hz and 15000Hz. The underwater acoustic remote control FM signal ...

The invention provides an underwater sound remote control method and a value-change decoding circuit. The underwater sound remote control method includes that a remote control party sends underwater remote control frequency modulated signals which are combined by a plurality of simple-frequency signals through a set arrangement sequence; and an underwater receiving party receives the underwater remote control frequency modulated signals, and detects the size and the permutation and combination sequence of the single-frequency signals contained in the underwater remote control frequency modulated signals, and compares the size and the permutation and combination sequence of the single-frequency signals with preset conditions. If the size and the permutation and combination sequence of the single-frequency signals all meet the conditions, a value-change motion signal command is outputted, and the underwater remote control frequency modulated signals are formed by the simple-frequency signals with three frequency ranges of 9000 Hz, 12000 Hz and 15000 Hz. The decoding circuit based on the remote control method comprises an impedance conversion and protection circuit, a crossover network, a comparator circuit and a single-chip microcomputer circuit, and peripheral equipment of the decoding circuit is a transducer. The underwater sound remote control method and the value-change decoding circuit can achieve an underwater sound remote control awakening function, and with regards to the types of decoding circuits designed through frequency modulation coding signals, the scale of the types of decoding circuits can not be large, and circuit complexity is not high.
Description
technical field [0001] The invention relates to an underwater acoustic remote control method and an underwater acoustic remote control value decoding circuit for receiving and processing underwater acoustic remote control signals, belonging to the technical field of underwater acoustic communication. Background technique [0002] Underwater acoustic remote control is a technology that uses sound waves to control underwater equipment. Usually, most underwater equipment is self-sustaining and relies on its own battery pack to provide working energy. It is difficult to support large-scale, Circuit complex remote control signal decoding circuit. However, under certain application conditions, complex control functions do not need to be implemented, as long as a simple wake-up command is completed. For example, underwater acoustic transponders commonly used in the field of marine engineering can be classified into this category. Contents of the invention [0003] In view of thi...
