AI Technical Summary
Technical Problem
When existing construction machinery is idling, the independent cooling system still maintains a large cooling capacity, resulting in fuel waste.
Method used
By collecting the temperature value of the construction machinery, the heat dissipation control logic is automatically adjusted. The idle speed control logic is only entered when the temperature is below the high temperature critical value. Otherwise, the idle speed control is not entered. The heat pump drives the fan to dissipate heat by calculating the displacement or the maximum displacement, thus avoiding idle speed control.
Benefits of technology
It effectively reduces heat dissipation power, avoids fuel waste, and improves energy utilization efficiency.

Abstract
The application discloses an engineering machine independent heat dissipation energy-saving control method and device, and the method comprises the following steps: collecting the current temperature value of a controlled object in the engineering machine; when the engineering machine enters an idle running state, comparing the collected current temperature value with a set high-temperature critical value; if the collected temperature value is greater than the set high-temperature critical value, the engineering machine does not enter the independent heat dissipation idle control logic; otherwise, the engineering machine enters the independent heat dissipation idle control logic. The application can automatically adjust the heat dissipation control logic according to the running conditions of the engineering machine and the temperature value collected by the independent heat dissipation system, effectively reduces the heat dissipation power, and avoids fuel waste.
