Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0028] The signal transmitting circuit of the inductive AUV system start-stop module is described as follows:

[0029] Such as figure 1 As shown, the signal transmission circuit of the inductive AUV system start-stop module is mainly composed of three modules, including MFRC522 radio frequency identification module, 51 single-chip microcomputer, and nRF24L01 radio frequency transmission module. The data communication between several modules adopts the SPI protocol. When the AUV system needs to be turned on, turn on the power switch in the signal transmitting module, and at the same time, touch the RF card to the RFID identification module. At this time, the signal light will flash, and the OLED screen will display on at the same time, indicating that the system has received the control signal and starts to process the signal. The receiving circuit sends sign...

Abstract

The invention discloses a start-stop device and method of an induction type AUV system, and belongs to the field of AUV control. The start-stop device includes a signal transmitting area and a signalreceiving area, wherein the signal transmitting area includes a radio frequency identification module, a display module, a signal transmitting area core control module and a wireless signal transmitting module; and the signal receiving area includes a wireless signal receiving module, a signal receiving area core control module and an AUV power supply control module. The start-stop method includesthe steps that module setting is firstly initialized; then power supply start-stop information is sent from the transmitting module to the receiving module; then commands are sent from the receivingarea core control module to the power supply control module according to the present information; then power supplying is directly operated by the power supply control module according to the start-stop information; and whether tasks are completed or not is judged. According to the start-stop device and method of the induction type AUV system, the problem that starting and stopping of an AUV are prone to being influenced by light is solved, anti-interference performance of the AUV in the start-stop process is enhanced, and requirements of normal operation of the AUV in complex environments aremet.

Description

technical field [0001] The invention belongs to the field of AUV (autonomous underwater vehicle, Autonomous Underwater Vehicle) control, and in particular relates to the control of starting and stopping of an AUV power supply circuit. Background technique [0002] As an unmanned diving device, AUV needs to perform various tasks underwater for a long time, which puts a strict test on the performance of AUV in design. As one of the cores of AUV, the power supply module of AUV determines the performance of AUV to a certain extent. Therefore, the design and improvement of AUV power supply module is of great significance. [0003] At this stage, the start and stop of some AUV power supply modules still need external assistance. At present, there are AUV start-stop modules based on infrared technology. The AUV start-stop module designed with wireless infrared technology is composed of two modules: a signal transmitting module and a signal receiving module. It uses a coder / decoder...
