Problems solved by technology

Excavators currently on the market are complex and diverse, all of which rely on diesel engines as power sources. They have disadvantages such as high energy consumption, low efficiency, complex control, complex variable parameters, and poor adaptability. They cannot quickly adapt to various harsh environments. Obviously, The actuating system of the existing excavator is far from meeting the demand in terms of mining efficiency, adaptability, energy saving, intelligence and performance. Therefore, the present invention provides a programmable controller-based electric cylinder power matching control for excavators. The key to the realization of this system is the management and matching of the input and output of the power supply. The battery pack is used for power supply, and the power is reasonably distributed under the condition of limited power supply. It has high mining efficiency, strong environmental adaptability, high degree of intelligence and The advantage of energy saving largely solves the problem that the existing actuation system cannot meet the demand

Abstract

The invention discloses an electric cylinder power matching control system for an excavator based on a programmable controller, which relates to the technical field of excavators in engineering vehicles and comprises the programmable controller, a power management system, a servo driver, a bucket rod electric cylinder, a bucket electric cylinder, a movable arm electric cylinder and an electric cabinet. The power supply management system comprises a circuit breaker, a power supply protector, an electromagnetic filter, a contactor, a rectification filter circuit, a protection circuit, an IGBT, a single-chip microcomputer, a communication circuit and a heat dissipation module. The method has the beneficial effects that the optimal power matching relation is obtained by performing multi-objective optimization on the speeds and the thrust of the three electric cylinders by utilizing a bionic algorithm, so that the energy-saving property and the economical efficiency of the excavator are greatly improved, and the method is high in intelligent degree, stable and durable in work, safe, controllable and higher in environmental adaptability.

Description

technical field [0001] The patent of the present invention provides a programmable controller-based electric cylinder power matching control system for excavators, which relates to the technical field of engineering vehicles. Background technique [0002] In recent years, excavators have been widely used in fields such as mines, bridges, farmland renovation, landscaping, pipeline construction, stonework, quarrying aggregates, etc. The requirements are also constantly increasing. The electric cylinder is an electric actuation system with high precision, high integration, strong environmental adaptability and light pollution. Excavators currently on the market are complex and diverse, all of which rely on diesel engines as power sources. They have disadvantages such as high energy consumption, low efficiency, complex control, complex variable parameters, and poor adaptability. They cannot quickly adapt to various harsh environments. Obviously, The actuating system of the exis...
