Key points of Marine Joysticks design

The design of the Marine Joysticks control stick needs to take into account the particularity of the Marine environment and operational requirements.

I. Environmental adaptability and durability

1. Material selection:

The main body is made of 316L stainless steel/aluminum alloy, with salt spray resistance treatment on the surface (salt spray test ≥1000 hours), and the handle is covered with anti-slip fluororubber.

2. Protective performance:

The interface seal reaches IP67 level, the circuit board is potting and waterproof, suitable for working temperatures ranging from -30 ℃ to 70℃, and resistant to ship vibrations from 5 to 200Hz.

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

II. Ergonomic design

1. Grip optimization

The handle support Angle (±15°) and length (5-8cm) can be adjusted, and the operating force is controlled at 2-5N · m to reduce fatigue.

2. Feedback System

① Touch: The vibration motor indicates an abnormality (such as overspeed);

② Visual: OLED screen displays rotational speed/rudder Angle, with automatic backlight adjustment.

③ Auditory: The buzzer indicates the operation status in stages.

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

III. Control Accuracy and Reliability

1. Sensing solution

Dual Hall sensors + magnetic encoder (accuracy ≤0.5°), CAN bus transmission delay ≤1ms.

2. Redundant design

The switching between the main and backup motors is ≤50ms, and the mechanical connecting rod emergency channel complies with the SOLAS convention.

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

IV. Safety and Compliance

1. Prevent misoperation:

The unlock button requires a force of 1.5kg, the emergency stop button has a response time of no more than 100ms, and supports RFID permission management.

2. Certification Standards:

It has passed the IMO, IEC 60945 and classification society certifications, and its EMC anti-interference complies with EN 60945.
