Abstract

The invention relates to a marine engine preemptive redundant electronic control system and method, belonging to the technical field of electronically controlled engines, comprising a fuel electronic control ECU group, an arbiter and an engine, wherein the fuel electronic control ECU group comprises a first fuel control ECU, A first crankshaft sensor, a first camshaft sensor, a second fuel control ECU, a second crankshaft sensor, and a second camshaft sensor. The electronic control system of the invention is simple, easy to operate and convenient for users to maintain. If one set of fuel electronic control ECU components fails and cannot work normally, the other set of fuel electronic control ECU components can automatically take over and control the fuel system of the engine. This ensures that the engine can continue to operate normally.

Description

technical field [0001] The invention belongs to the technical field of electronically controlled engines, and relates to a preemptive redundant electronic control system and method for a marine engine. Background technique [0002] The fuel injection of the electronically controlled marine engine is controlled by the fuel control ECU. Once the fuel control ECU fails and the fuel cannot be injected normally, people cannot directly operate the fuel injection structure, so the engine will stop working. When the ship is running and encounters a harsh environment, if the ship loses power, it may lead to catastrophic consequences. Therefore, ship regulations all over the world require that as long as the marine main thrust electronically controlled engine is used for a single engine and a single propeller, its The electronic control system must have a redundant design. [0003] At present, the existing redundancy solutions all use the master-slave ECU method, one is the main cont...
