In order to occupy a place in the excavator market competition, many foreign well-known excavator manufacturers have proposed energy-saving control systems with independent intellectual property rights. The representative energy-saving control products of these companies mainly include PMS system of O&K, CAPS system of Link-Belt, EPC system of Caterpillar, OHS system of Hitachi, OLSS system of Komatsu, APC system of Kato, ITCs system of Kobelco, EPOS system of Daewoo, etc. The following Hitachi control system for a brief analysis.
Using the fuzzy reasoning principle, it can identify different excavation conditions, such as loading, leveling, soil spreading and other operations, and automatically carry out auxiliary operations, so as to optimize the output power of diesel engine, maximize the work efficiency and save fuel to the maximum extent.
