Embodiment Construction
[0030] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.
[0031] The general cooling fan of the hydraulic system of the crane is a fixed speed fan, and the cooling control of the hydraulic system is realized through the opening and closing control of the fan. The traditional way is: when the hydraulic oil temperature is less than a certain fixed value W 1 When the fan is turned off, when the hydraulic oil temperature is greater than a fixed value W 2 when the fan is turned on. The existing cooling fan control strategy does not consider factors such as operating conditions, load rate and ambient temperature. The setting of the opening and closing temperature is determined by the user's experience. The opening and closing tempe...

The invention relates to the field of construction machinery, and discloses a control method for a hydraulic oil cooling system, which is applied to equipment including an engine and a hydraulic oil cooling system. The hydraulic oil cooling system includes a cooling fan, and the working state of the cooling fan includes an open state and a In the shutdown state, the control method includes: acquiring relevant data of the device within a preset time period, wherein the relevant data includes hydraulic oil temperature, ambient temperature and engine load rate; inputting the relevant data and the preset time interval into a pre-trained temperature prediction model, To obtain the predicted temperature after the preset time interval output by the temperature prediction model; control the cooling fan according to the predicted temperature, the current hydraulic oil temperature at the current moment, and the pre-stored target hydraulic oil temperature upper limit value and target hydraulic oil temperature lower limit value working status. The invention can improve the working efficiency of the hydraulic oil cooling system.
Description
technical field [0001] The invention relates to the field of construction machinery, in particular to a control method, a control device and a processor for a hydraulic oil cooling system. Background technique [0002] The hydraulic system is an important part of some equipment (for example, cranes). Taking cranes as an example, the actions such as getting on the car completed by the crane are realized by hydraulic oil as the medium, so the life of the hydraulic oil directly affects the performance and reliability of the whole vehicle. sex. With the increase of working time, the variability of working environment and working conditions, the change of oil temperature is more complicated. Therefore, the hydraulic oil cooling system is very important for the hydraulic system. The hydraulic oil cooling system of the existing equipment usually includes a cooling fan, and the cooling fan is usually a constant speed fan, that is, the cooling control of the hydraulic system is real...
