Embodiment 2

[0046] The present invention also provides an underwater control system, wherein the system at least includes an underwater remote controller and underwater equipment.

[0047] The underwater equipment involved in this embodiment includes various equipment that operate in the underwater environment, such as: unmanned ship, submarine, AUV (Autonomous Underwater Vehicle, autonomous underwater vehicle), UUV (Unmanned Underwater Vehicle) , unmanned underwater vehicles), etc.

[0048] Underwater robots are mainly divided into two categories: one is a cable underwater robot, which is commonly called a Remote Operated Vehicle (ROV for short); the other is a cable-free underwater robot, which is customarily called an autonomous underwater vehicle. Vehicles or Autonomous Underwater Vehicles (AUVs). Autonomous underwater robot is a new generation of underwater robot. It has the advantages of large range of activities without being restricted by cables, good maneuverability, safety, goo...

Embodiment 3

[0058] Figure 4 is a flow chart of the evaluation method of the unit use effect according to the embodiment of the present invention, such as Figure 4 As shown, the method includes the following steps:

[0059] Step S401, based on the principle of phase shift keying, modulate the preset communication signal according to the carrier signal to obtain the control signal;

[0060] Step S402, sending a control signal to the underwater device; wherein, the control signal is used to control the underwater device to perform a corresponding operation.

[0061] In specific implementation, for how to realize the modulation processing of the preset communication signal, this embodiment provides a preferred implementation mode, that is, band-pass filter processing is performed on the preset communication signal; according to the carrier signal, the band-pass filter processed The preset communication signal is subjected to coherent processing; wherein, the carrier signal is consistent w...

Abstract

The invention discloses an underwater remote control, an underwater control method and system. The underwater remote control comprises a signal processor and a signal transmitter, wherein the signal processor is used for modulating a preset communication signal according to a carrier signal based on a phase shift keying principle so as to obtain a control signal; the signal transmitter is used fortransmitting the control signal to underwater equipment; and the control signal is used for controlling the underwater equipment to execute corresponding operations. According to the technical schemeof the invention, the underwater remote control is capable of modulating the preset communication signal according to the carrier signal based on the phase shift keying principle so as to obtain a binary control signal, and corresponding control of the underwater equipment is realized by virtue of the binary control signal. Therefore, the influences of factors such as background environment complexity, multi-path effects of channels, a time-changing effect, narrow bandwidth of a communication band, serious attenuation of the signal along with a propagation distance and the like on underwatercommunication are avoided as much as possible, the underwater equipment is effectively controlled, and the communication effect of the underwater equipment is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an underwater remote controller, an underwater control method and a system. Background technique [0002] Underwater communication generally refers to the communication between a surface entity and an underwater target (such as a submarine, an unmanned submersible vehicle, an underwater observation system, etc.) relative to land or space communications. Underwater wireless communication is an important component of underwater communication technology. It is the key support for underwater monitoring, underwater development and underwater military struggle. In order to compete for underwater resources and enhance underwater combat capabilities, underwater wireless communication has cost It is one of the important communication technologies that world powers are competing to develop. [0003] At present, the difficulties of underwater communication mainly lie in: th...
