Management and control method and system of winch system and operation machine

Abstract

The invention provides an energy management and control method and system and operation machinery, and relates to the technical field of operation machinery, and the method comprises the steps: inputting a request rotating speed to a winch motor controller in a winch system of the operation machinery; the actual rotating speed of a winch motor in the winch system is obtained; whether the winch system breaks down or not is judged based on the request rotating speed and the actual rotating speed; when it is judged that the winch system breaks down, a brake of the winch system is controlled to be started, and the winch system is braked. The method is used for overcoming the defect that in the prior art, when a winch system of an operation machine breaks down, falling of a load can be stopped only by manually pressing down a brake button, so that the use safety coefficient of the operation machine is not high, automatic fault judgment and processing of the operation machine are achieved, the load is effectively prevented from directly falling to the ground, and safety of the operation machine is improved. And the use safety of operation machinery is improved.

Description

technical field [0001] The invention relates to the technical field of working machines, and in particular, to a control method, system and working machine for a hoisting system. Background technique [0002] A work machine equipped with a hoisting system can lift or lower the load to a designated position as required. In the process of lifting the load of the work machine, the engine of the work machine can drive the hydraulic system to drive the hoisting system to lift the load, and in the process of lowering the load of the work machine, the balance valve of the work machine can lower the load, lower the arm and lift the retractable arm. To the speed limit effect, so as to avoid the accelerated falling of the load, resulting in a hoisting accident. [0003] At present, when the hoisting system of the working machine fails, the general treatment method is to use the balance valve to stop the load falling. However, when the hoisting system of the working machine fails, the...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a hoisting system management and control method, system and operating machine, which are used to solve the problem that in the prior art, when the hoisting system of the operating machine fails, the load can only be stopped by manually pressing the brake button. The defect caused by the low safety factor of the operating machinery can realize the automatic judgment and processing of the failure of the operating machinery, effectively prevent the load from falling directly, and improve the safety of the operating machinery
