Problems solved by technology

[0003] However, the disadvantages of this method are: (1) Once the drive fails, it is difficult to locate the faulty component; (2) A certain part of the drive fails, which may cause other normal parts of the drive to be unusable; (3) The use of the drive The range is limited, that is, if a certain part of the three parts of the driver does not meet the requirements for use, the entire driver will not be available; (4) The overall length and width of the driver are large, and when installed inside the circular airtight cabin of the underwater robot, The arc-shaped space around the driver is not effectively used, making the utilization of the space inside the airtight cabin of the underwater robot low

Embodiment Construction

[0043] The technical solutions of the present invention will be described in detail below, but the protection scope of the present invention is not limited to the embodiments.

[0044] Such as figure 1 As shown, the DC24V power supply module supplies power to the PWM power amplifier module, thereby indirectly supplying power to the thruster. The current detection module is connected in series between the DC24V power supply module and the PWM power amplifier module to detect the working current of the thruster in real time, and the current detection result is simulated The form of the voltage signal is output to the A / D input port of the main control CPU module through the signal output port Sout.

[0045] Such as figure 1As shown, the DC12V power supply output module outputs DC12V power supply voltage, which is converted into DC5V by the LM2596S chip and then supplies power to the main control CPU module. The main control CPU module is composed of PC104CPU module, A / D board, ...

Abstract

The invention discloses an underwater robot propeller modular drive circuit and a driving method thereof. A current detection module detects working current of a propeller in real time; current detection results are transmitted to a master control CPU (central processing unit module) in analog voltage signal form; the master control CPU module receives the information about the current detection results and generates corresponding control voltage signals according to actual conditions; an A-PWM (analog pulse width modulation) module receives the control voltage signals from the master controlCPU module, converts them into PWM signals and transmits the PWM signals to a PWM power amplification module so as to control speed and output push of the propeller.

Description

technical field [0001] The invention belongs to underwater robot technology, and in particular relates to a modular driving circuit and a driving method for a propeller of an underwater robot. Background technique [0002] With the decrease of non-renewable resources on land, the development and utilization of marine resources has gradually been paid attention to by people. Ocean development requires advanced operating tools. Underwater robots are widely used in the development of marine resources because of their safety, high efficiency, large operating depth, and ability to work underwater for a long time. The thruster is an important power device of the underwater robot, which pushes the underwater robot to complete the corresponding tasks. The control principle of the thruster is: the main controller of the underwater robot generates a control voltage signal, which is amplified by the driver to control the thruster to generate corresponding thrust, and at the same time...
