Detailed ways

The following non-limiting examples are used to further illustrate the present invention and understand the present invention.

The present invention is an electrical control system suitable for an unmanned rescue ship. It includes electrical components arranged on the rescue ship. The electrical components include a power switch module, a power module, a motor drive module, a receiving module, and a receiving module connected by a connecting cable. The matching remote control, control board, radiator, motor adopts water-cooled motor, and the connecting cable is fixed in the rescue boat with a cable tie.

The power switch module controls the power module. The power module supplies power to the motor drive module. The motor drive module is equipped with a receiving module and powers it. The receiving module controls the operation of the motor drive module. The control board is connected to the power module and monitors the power module and the motor drive module. There is a radiator.

The control board has undervoltage protection and overcurrent protection functions. When the control board detects that the power supply voltage is 30% of the rated voltage, the controller outputs a switch signal every 2S to control the light strip, and reminds the user with the flashing of the light strip that the battery is in a low voltage state and needs to return; when the control panel detects the working current When it reaches 85A, the control board outputs a switch signal, disconnects the switch control interface of the ESC, and disconnects the output of the ESC. It will automatically recover after 10S.

It also includes a steering control module, which is connected to the receiving module through a connecting cable, and the receiving module controls the steering control module.

When in use, the remote control uses the Futaba Electronics 3PL-2.4G gun-type remote control, which is a one-way three-channel intermediate 2.4G remote control. The remote control uses a segmented LCD screen with high-brightness LED indicator, with alarm function, ABS braking system, steering control function, throttle control and other functions.

The steering control module is used to adjust the direction of the unmanned ship's jet pump. It is proposed to use TRA2056 from TRAXXAS. Steering control module size: 40.5X20.5X36mm, weight 45g, action time 0.23s/60°, the steering control module is controlled by the remote control receiving module.

The receiving module uses Futaba's R2104GF 4-channel S-FHSS receiver. The receiving module is used in conjunction with the remote control 3PL-2.4G gun-type remote control. The normal working voltage range of the receiving module R2104GF is 3.5V-8.4V. In this control scheme, the motor drive module provides power to the receiving module, and the output terminal of the receiving module is connected to the motor drive module. The receiving module has its own antenna, 1 is the steering control port, and 2 is the throttle control port. As shown in Figure 1, the circuit diagram of the receiving module. In the figure, X11 and X12 are JST three-core plug-ins, the red and black are power lines, the working power comes from the motor drive module, and the white is the signal output terminal, which is connected to the motor drive module. XS6 is a throttle control plug-in, and XS7 is a steering control plug-in. X3 is an antenna, which is self-connected to the receiving module and has a length of 100mm.

As shown in Figure 2, it is the peripheral circuit diagram of the motor drive module. The motor drive module uses Haifei general DC motor drive module, the model is Swordfish Pro 200A-8S. The drive module comes with dual water cooling pipelines, the switching frequency is adjustable, and there are three options of 8KHz/12KHz/16KHz. There are two shutdown modes: software shutdown and hardware shutdown. The motor drive starts smoothly, and the overheat protection point is 100 degrees. During the operation of the drive motor, if the motor reverses, adjust two of the motor wires arbitrarily. The module has a maximum operating voltage of 35V and a maximum current of 200A. The motor drive module has good compatibility and can meet the needs of different DC brushless motors without adjusting its control software.

The power supply module uses castle company, and the model specification is CC-BEC 10AMP PEAK. The module has a maximum output current of 10A, an input voltage range of 5V-25.2V, and an output of 5V. The power switch module is the power input control part of the system, and IRC’s SPS SafetyPowerSwitch 34V 100/200A is selected. The main function of this module is to prevent sparks or large currents from impacting the motor drive module during the battery connection, and at the same time control the on/off control of the entire control unit through the switch control unit connected to it.

As shown in Figure 3, it is the power switch module. In Figure 3, X2 is connected to the battery pack, and X1 is the output terminal of the power switch module. This port provides power to the DC motor drive module. X8 is a four-core connector, which is a switch input signal. The X14 terminal is a two-core watertight plug-in. The plug-in provides power for the light strips and indicator lights of the floating body.

The power switch uses IRC's SPS gas cap switch actuator (green LED), and the model is A72020. This switch is used in conjunction with the power switch module. The switch only generates a switch signal to input to the power switch module, instead of directly cutting off the power. The action of the switch mainly depends on the external magnet block. Putting the magnet in is the "off" signal, pulling out the magnet is the "on" signal. In the on state, the green LED on the power switch lights up. When an error occurs or the power supply voltage is too low, the indicator flashes.

The motor uses XTEAM's internal rotating 4-pole brushless DC motor, the motor model is XTI-54118/3D, this motor is suitable for ships of 900mm-1500mm. The diameter of the motor is 54mm and the length is 118mm. The shaft diameter of this motor is 8mm and the shaft length is 20mm. After calculation, the motor can reach 13368rpm/min at 25.9V, which can meet the requirements.

In summary, the present invention is used to control various hardware on the rescue ship, so as to ensure that the rescue ship can rescue drowning or drowning people, approach detection and observation of dangerous areas, sonar detection of sub-water areas, submarine sonar scanning, and water quality detection Sampling, hydrological flow measurement, urban river and lake surface cleaning, water surveying and mapping, automatic nesting and fish hunting.
