Engineering machinery control method and engineering machinery
The invention relates to the technical field of engineering machinery, in particular to an engineering machinery control method and engineering machinery. The method comprises the steps of determining a dangerous area of an execution component of the engineering machinery; if the execution part enters the dangerous area in the actuation process, the opening degree of the electromagnetic proportional valve is adjusted to reduce the flow entering an oil cylinder of the execution part so as to reduce the movement speed of the execution part, whether the execution part is away from the dangerous area or not is detected in real time, and if it is judged that the execution part is away from the dangerous area, the opening degree of the electromagnetic proportional valve is controlled to be fully open; the flow entering the oil cylinder of the execution part is the maximum value, and the execution part acts at the maximum speed. And the execution part can be prevented from colliding with an obstacle due to high speed in the working process. And the execution part is protected on the premise of ensuring that the whole engineering machinery is not shut down. The flow of oil entering the oil cylinder of the execution component is reduced, so that the action of other components can be prevented from being influenced, and the purpose of accurately controlling the movement speed of the execution component is achieved.
本发明涉及工程机械技术领域，尤其涉及一种工程机械控制方法及工程机械。方法包括确定工程机械的执行部件的危险区域；若执行部件在作动过程中进入危险区域，则调节电磁比例阀的开度以降低进入执行部件油缸的流量以使执行部件的运动速度降低，并实时检测执行部件是否远离危险区域，若判定执行部件远离危险区域，则控制电磁比例阀的开度为全开，进入执行部件油缸的流量为最大值，执行部件按照最大速度动作。能够防止执行部件在工作过程中因速度较快而与障碍物碰撞。保证在工程机械整体不停机的前提下保护执行部件。降低进入执行部件油缸内油液流量能够避免其他部件动作受到影响，实现精确控制执行部件的运动速度的目的。
