The functions of the main engine of a ship mainly include providing power, propelling the ship's navigation, and controlling the ship's speed and direction. Marine main engine remote control is a way of remotely controlling the main engine from the bridge or centralized control room away from the engine. Marine main engine remote control can not only improve the working conditions of engine management personnel and the ship's maneuverability, but also improve the safety of ship navigation, as well as the reliability and economy of the main engine's operation. The main engine remote control system is an important part of engine automation, and it is also the focus and difficulty of engine personnel in managing and using automated equipment.

[0003] However, the existing ship main engine remote control system still has 1) security issues: the remote control host may be vulnerable to hacker attacks, resulting in loss of control or hijacking of the ship operation; 2) communication delay: since the ship main engine remote control system needs to transmit instructions through wireless communication, there is a certain delay, which may affect the real-time and accuracy of the operation; 3) technical dependence: the ship main engine remote control system relies on highly technical equipment and networks.
