AI Technical Summary

Technical Problem

When existing lithium iron phosphate batteries are used as a power source for ships, they only have one control system, which cannot effectively perform emergency operation functions in case of emergencies, causing the ship to lose power.

Method used

An emergency redundant control system is added to the conventional control system. By combining the conventional propulsion control module and the emergency propulsion control module, the battery pack control system, the local control box for electric propulsion and the propulsion system, the system can combine program communication control with hard-wired switch quantity and analog quantity control to ensure that the system can still operate normally in the event of a fault.

Benefits of technology

This enables redundant control of the ship's power system in the event of a control module or communication failure, ensuring normal operation even in emergency situations and improving the safety and reliability of the ship's power system.

Abstract

The utility model relates to a redundancy control electric propulsion system, which is characterized in that an emergency propulsion control module is additionally arranged on the basis of an original conventional propulsion control module, so that redundancy of a power control system is realized, and the problem that under the existing mode, a single system of the propulsion system is non-independent, so that the propulsion system is not independent when an emergency situation occurs on a ship is solved. The system solves the problem that the prior art cannot well achieve the operation function under the emergency condition, and achieves the effect that the system can still carry out the emergency operation under the condition that a communication or control module breaks down through the control thought that a program communication control scheme and a hard wire switching value and analog quantity control scheme are combined.
