Abstract

The invention relates to the technical field of engineering machinery, in particular to a fan system for engineering machinery and a control method. The fan system for the engineering machinery involves a signal acquisition module, a fan control module, and a fan group, wherein the signal acquisition module is used for acquiring a temperature signal and a working condition signal of a whole vehicle; the fan control module is electrically connected with the signal acquisition module; the fan group is electrically connected with the fan control module; and the fan control module is configured to control the fan group according to the temperature signal and the working condition signal. The fan system can adjust the rotating speed of the fan group according to different working conditions, so that the working efficiency of the whole vehicle is ensured.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a construction machinery fan system and a control method. Background technique [0002] At present, the main method of fan control commonly used in construction machinery is: the vehicle controller mainly analyzes the data of hydraulic oil temperature, coolant temperature and intake air temperature, and controls different fans to rotate at different speeds according to different temperature values. Fans cool different objects. The fan group can be made in different combinations for heat dissipation. The fan terminal receives the data signal sent by the vehicle controller, and realizes the fan speed control function according to different signals. [0003] In traditional engineering machinery, the controller of the whole vehicle changes the PWM signal of each fan group according to the hydraulic oil temperature, coolant temperature and intake air temperature to con...
