Engine control device for building machinery

Abstract

The invention provides an engine control device for building machinery. The device comprises an engine, the engine is fixed on the upper surface of a support frame, a storage battery, a first starter and a second starter are arranged on the right side of the engine, the first starter and the second starter are both in meshing connection with one end of a crankshaft on the engine through a starting gear, the storage battery is electrically connected with a microprocessor module through a wire, the microprocessor module is electrically connected with the first starter and the second starter through wires, the microprocessor module is electrically connected with a temperature detection sensor, a rotating speed detection sensor and an electric quantity monitoring module in sequence through wires, and the electric quantity monitoring module is electrically connected with the storage battery through a wire. According to the engine control device for building machinery, high and low speed operation of the engine can be controlled, the service life of the first starter and the second starter can be prolonged, the efficiency of energy loss is reduced, and the energy-saving effect is good.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to an engine control device for construction machinery. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy. It was first born in the UK. It is not only applicable to power generation devices, but also refers to the entire machine including power devices (such as: gasoline engines, aero engines). The types include, for example, internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, and the like. [0003] When the currently used engine is running, a single starter is generally used to start and control the operation of the engine, which causes it to be easily shaken by the vibration generated by the running of the engine, reducing the stability of the starter's control of the engine's operation, and by A single starter controls the high ...
