Calibration method and device of engineering machinery, control method and device of engineering machinery, engineering machinery and medium
The embodiment of the invention discloses a calibration method and device of engineering machinery, a control method and device of the engineering machinery, the engineering machinery and a medium, and belongs to the technical field of equipment control. The calibration method of the engineering machinery comprises the following steps: in response to a received power calibration request, determining a calibration loading rate corresponding to the absorption power of a main pump at the current altitude; according to the atmospheric pressure and the altitude coefficient corresponding to the current altitude, the recommended absorption power of the main pump at the current altitude is determined; adjusting the real-time absorption power of the main pump to the recommended absorption power based on the calibrated loading rate; a speed reduction value of the engine is obtained, and whether the speed reduction value is smaller than or equal to a preset speed reduction threshold value or not is determined; and under the condition that the speed-down value is larger than a preset speed-down threshold value, the recommended absorption power of the main pump is updated based on the obtained power correction till the speed-down value is smaller than or equal to the preset speed-down threshold value, and the recommended absorption power serves as the calibrated absorption power. The absorption power and the loading rate are calibrated in advance, so that the phenomenon that the engineering machinery falls down and shuts down is avoided.
本申请实施例公开了一种工程机械的标定方法、控制方法、装置、工程机械及介质，属于设备控制技术领域。工程机械的标定方法包括：响应接收到的功率标定请求，确定当前海拔下主泵的吸收功率对应的标定加载速率；根据当前海拔对应的大气压力和海拔系数，确定当前海拔下主泵的推荐吸收功率；基于标定加载速率，将主泵的实时吸收功率调整至推荐吸收功率；获取发动机的掉速值，并确定掉速值是否小于或等于预设掉速阈值；在掉速值大于预设掉速阈值的情况下，基于获取到的功率修正量，更新主泵的推荐吸收功率，直到掉速值小于或等于预设掉速阈值，将推荐吸收功率作为标定吸收功率。通过预先标定吸收功率及加载速率，避免工程机械出现掉速憋车现象。
