Automatic start-stop control method and system for excavator engine

Abstract

The invention relates to engine control and aims to solve the problem that an existing excavator group cannot be stopped at a proper time to save energy during idle speed waiting. The invention provides an automatic starting and stopping control method and system for an excavator engine, and the control method comprises the following steps: collecting operation data, uploading the operation data to a big data analysis platform, analyzing and determining target excavators working in the same region under the same working condition, and sending the idling ratio of a computer group to each target excavator; the target excavator displays shutdown information about whether the engine is shut down or not on an instrument according to the state of the target excavator and the machine group idle speed ratio; controlling the engine to flame out or operate according to the instrument selection instruction; after flameout, a pilot operation signal is detected to automatically start the engine; according to the overall busy degree of machine group operation, a suggestion whether to stop or not is given, and energy is further saved.

Description

technical field [0001] The present invention relates to an engine control, and more particularly, to an excavator engine automatic start-stop control method and system. Background technique [0002] In large infrastructure sites, it is common to have excavator fleets operating, that is, the same model is used for the same operation at the same work site. For example, in large excavation sites, multiple excavators are used for excavation and loading operations. When the excavator driver is operating the excavator for loading operations, he needs to wait for another truck to park in the loading area for each full truck before continuing the loading operation. The length of the waiting time depends on the overall coordination ability of the construction site. If the waiting time is too long, the idling time of the whole machine will be too long, which will easily cause carbon deposition and loss of the engine. At the same time, it will also waste a lot of energy, increase the e...
