Embodiment Construction

[0028] Such as figure 1 As shown, a method for waking up an underwater acoustic communicator based on a multi-tone signal comprises the following steps:

[0029] (1) Initialization

[0030] 1) The communication transducers of the transmitting node and the receiving node of the underwater acoustic communicator enter the water, complete power-on and self-inspection respectively, and confirm that the self-inspection status of each board is normal;

[0031] 2) The underwater acoustic communication machine as the transmitting node completes the interface test with the host computer. The data interface includes but not limited to serial port (RS232 / 422 / 485) and network port (RJ45) to ensure that the data sent by the host computer can be correctly received.

[0032] (2) Signal emission

[0033] 1) The underwater acoustic communicator as the transmitting node receives the data to be sent from the host computer through the data interface;

[0034] 2) The underwater acoustic communic...

Abstract

The invention discloses an underwater acoustic communication set awakening method based on multiple single-tone signals, and belongs to the technical field of underwater acoustic communication. The method comprises the steps of signal transmitting, signal receiving, wake-up signal capturing and the like. The method is used for remote wake-up of the underwater acoustic communication set, has low algorithm complexity, can effectively improve the capture success rate of the wake-up signal of the underwater acoustic communication set, can realize that the wake-up signal carries prior information by setting single-tone signals with different frequencies, and improves the subsequent information demodulation and decoding processing speed of the underwater acoustic communication set; meanwhile, by setting the false alarm detection frequency, false alarms caused by broadband interference signals to the underwater acoustic communication equipment can be effectively resisted.

Description

technical field [0001] The invention relates to the technical field of underwater acoustic communication, in particular to a method for waking up an underwater acoustic communication machine based on multi-tone signals. Background technique [0002] With the improvement of the strategic position of the ocean, the acquisition and processing technology of ocean-related information has attracted more and more attention, and scientific researchers are increasingly keen on the development of marine resources and the research of underwater communication technology. Marine data is the key basis for enriching marine technology application scenarios, including data generation, collection, storage, transmission and processing. As an effective means of underwater remote data transmission, underwater acoustic communication has become a key research topic for major maritime countries. Designing and developing low-cost, high-energy-efficiency, safe and reliable underwater acoustic communi...
