Battery switching management system and method in AUV

Abstract

The invention relates to a battery switching management system and method in an AUV (Autonomous Underwater Vehicle). An AD detection module is connected with a battery module for collecting the battery voltage. A single-chip microcomputer main control module is connected with the AD detection module for receiving a digital signal of the battery voltage sent by the AD detection module. The single-chip microcomputer main control module is connected with a relay module for judging the status of the current battery module according to the received digital signal of the battery voltage and sendinga control signal to the relay module to control the on-off of the relay module so as to complete power supply line switching. When a sailing body battery supplying power to AUV sailing body equipmentor a load battery supplying power to load equipment fails, the battery is automatically switched to the other side through the battery switching management system to continue emergency power supply for the corresponding equipment so that the operation of the basic functions of the sailing body is ensured and the sailing body can make a return voyage. The mode of mutual backup of two batteries greatly improves the reliability of the power supply system and ensures the normal operation of AUV.

Description

technical field [0001] The invention relates to the field of power management, in particular to a battery switching management system and method in an AUV. Background technique [0002] In AUV, in order to prevent the electromagnetic interference between the vehicle equipment and the load equipment, the vehicle battery and the load battery are often configured independently. The vehicle equipment related to the carrier navigation is powered by the vehicle battery, and the load equipment is powered by the load battery. , that is, complete electrical isolation. Since the AUV sometimes needs to sail underwater for a long time, when the battery power is too low or fails to supply power to the equipment normally, it will cause the equipment in the AUV to fail to work normally, and seriously cause the AUV to lose power and communicate with the outside, causing the carrier lost. [0003] In order to ensure the reliability of the entire AUV system, the relationship between the two...

[0004] However, when the power supply is directly switched between two sets of completely electrically isolated batteries, it will cause a certain period of power supply interruption for the electrical equipment, plus the pre-discharge time of the battery (battery pre-discharge is generally about 2s, The output voltage is unstable during the pre-discharge process), which often makes the power supply interruption last for several seconds, which will easily cause the work of the electrical equipment to be interrupted
