Key points of azimuth control panel design

The design of Marine full-rotation control panels needs to take into account high-precision control, multi-system collaboration, human-machine safety and adaptability to complex working conditions.

I. Control Logic Optimization

1. Single-lever Integrated Control: Use a 6DOF (six degrees of freedom) joystick to achieve composite control of forward/backward thrust, left/right traverse, and rotation angle with ±2% accuracy.

2. Dual-mode Switching:

1）Single-handle mode: Automatically distributes loads across multiple thrusters for routine operation.

2）Dual-handle mode: Independently controls bow/stern thrusters, with interlock functions to prevent misoperation.

3. Stepless Speed Regulation & Locking: Thrust can be continuously adjusted from 0–100%, with key gears (e.g., low-speed in port) lockable.

--------------------------------------------------------

II. Ergonomic Design

1. Layout Zoning:

1）Main control area: Joystick (with non-slip grip), mode selector knob, emergency stop button (red, requiring twist reset).

2）Display area: Real-time screen showing thrust vector, power, oil temperature, etc. (refresh rate ≤0.5s), with abnormal data flashing red.

3）Auxiliary area: Lights/horn control, backup mechanical knobs (for electronic failure redundancy).

2. Anti-misoperation Design: Critical actions require "combination button + joystick movement" confirmation (e.g., pressing Shift key + pushing joystick).

3. Force Feedback Indication: Joystick resistance increases with thrust level (e.g., +30% resistance at 80% thrust).

--------------------------------------------------------

III. Environmental Adaptability & Reliability

1. Protection Standards:

1）IP66 waterproof housing, salt spray test ≥1,500 hours; materials: 316L stainless steel/anodized aluminum.

2）Operates at -25°C~65°C with low-temperature heating and high-temperature air cooling.

2. Redundancy Design:

1）Dual power supply (main power + emergency battery, switching ≤10ms), dual CAN bus for anti-interference.

2）Modular design for joystick/display, replaceable within 15 minutes.

3. Vibration & Shock Resistance: Potted circuit boards, cushioned display panels, compliant with ISO vibration standards.

--------------------------------------------------------

IV. Safety & Compliance

1. Access Control: Multi-level passwords (separating operator/engineer permissions), with operation logs.

2. Emergency Response:

1）Backup battery sustains operation ≥4 hours in main power failure.

2）Links with fire alarm systems to automatically adjust thrusters to a safe position in emergencies.

3. Certification Requirements: Compliant with IMO MSC.461, IEC 60092 standards, and classification society (e.g., DNV GL) type approval.

--------------------------------------------------------

V. Maintenance & Scenario Adaptation

1. Self-diagnosis Function: Pre-boot sensor accuracy checks, fault codes exportable via USB.

2. Scenario-specific Modes:

1）Berthing mode: Low-speed micro-control (accuracy ±0.1 knots), automatic heading hold (deviation ≤±5°).

2）Emergency mode: One-key release for entangled debris, compatible with dynamic positioning (DP) systems.
