specific Embodiment approach 1

[0047] Specific implementation mode one: the following combination Figure 1 to Figure 5 This embodiment will be described.

[0048] AUV system block diagram see figure 1As shown, the AUV includes a communication module, a main control module, an on-duty module, a main control power supply and a communication power supply; the main control power supply provides working power for the main control module, the communication power supply provides working power for the The power supply is controlled to turn it on and off. The communication module communicates with the mother ship, and the mother ship communicates with the communication module through underwater acoustic commands to control the AUV working underwater. If the communication module fails, the underwater AUV loses contact with the mother ship, and a loss event occurs.

[0049] This embodiment provides a communication method, which monitors the working status of the main control module and the communication module, an...

Abstract

The invention discloses a communication method of an AUV (Autonomous Underwater Vehicle) module, belongs to the field of underwater vehicles, and aims to solve the problem of poor stability of an AUVsystem due to no watchdog of a communication module. The method comprises the following steps that 1, a main control module and a communication module are powered on; simultaneously executing the steps 2, 3 and 4; 2, judging the working states of the communication module and the main control module by utilizing the communication module to send a heartbeat packet to the main control module and receiving return information of the main control module; 3, the on-duty module obtains the working states of the communication module and the main control module by inquiring the communication module; 4,the on-duty module obtains the working states of the main control module and the communication module by inquiring the main control module; if the working state of the main control module is abnormal,the main control module is restarted; and if the working state of the communication module is abnormal, restarting the communication module. And controlling the AUV to emergently float upwards if theAUV is still abnormal after being restarted for multiple times.

Description

technical field [0001] The invention belongs to the field of underwater vehicles and relates to the system stability of underwater vehicles. Background technique [0002] AUV (Autonomous Underwater Vehicle) is a submersible that can autonomously complete set tasks underwater with the assistance of support platforms such as land base stations and surface ships. AUV initially completed work related to the civilian field, such as salvage of accidental ships, underwater environmental topography exploration, underwater cable construction, underwater equipment deployment, maintenance and recovery, etc. However, because it can carry a variety of sensors, special equipment, and underwater countermeasure weapons, it can complete many difficult military missions. Its military value is concerned by more and more countries, and is also regarded by the navies of various countries as a "power multiplier" in naval equipment. It occupies a high position and proportion in the military equip...
