Excavator system control method and device, storage medium and excavator system
The invention provides a control method and device of an excavator system, a storage medium and the excavator system.The method comprises the steps that the current backflow temperature serves as a judgment benchmark, and under the condition that the current backflow temperature is smaller than or equal to a preset temperature threshold value, the absolute value of a temperature difference value is obtained; the temperature difference value is the absolute value of the difference value between the current backflow temperature and the preset temperature threshold value, finally, the first target opening degree is determined to be the opening degree corresponding to the absolute value of the temperature difference value, the opening degree of the first oil return throttling valve is adjusted to be the first target opening degree, and the second oil return throttling valve is closed. Therefore, the heating speed is increased, and the problem that in the prior art, when the hydraulic oil temperature of two parallel one-way valves in an excavator is low and rapid heating is needed, return oil cannot be directly controlled not to pass through a cooler, and heating is too slow is solved.
本申请提供了一种挖掘机系统的控制方法、装置、存储介质和挖掘机系统，该方法通过以当前回流温度作为判断基准，在当前回流温度小于或者等于预设温度阈值的情况下，获取温度差值绝对值，即当前回流温度和预设温度阈值的差值的绝对值，最后确定第一目标开度为与温度差值绝对值对应的开度，并将第一回油节流阀的开度调节为第一目标开度，并关闭第二回油节流阀，从而相比现有方案能够控制回油油液不经过冷却器，从而提高了加热速度，进而解决了现有技术的挖掘机中并联的两个单向阀在液压油液温度较低，需要快速加热时，无法直接控制回油油液不经过冷却器而导致加热过慢的问题。
