Independent cooling system control system

Abstract

The invention belongs to the technical field of control system development and model development of independent cooling systems for engineering machines and special vehicles, and particularly relatesto an independent cooling system control system. The independent cooling system control system includes an input module, a calibration parameter setting module, a diagnostic module, a function management module, a rotational speed estimation module and a solenoid valve control module. By means of the independent cooling system control system, through independent cooling system control model framework dividing and designing, the system function implementation process is clear and smooth, sub-function module task definition is clear, the code readability is high, maintainability is good, the versatility and modularity of the control system are greatly improved, and the development efficiency and portability of the control system are improved.

Description

technical field [0001] The invention belongs to the technical field of control system development and model development of independent heat dissipation systems of engineering machinery and special vehicles, and in particular relates to an independent heat dissipation system control system. Background technique [0002] With the continuous improvement of national energy conservation and emission reduction standards, the heat dissipation system of construction machinery and special vehicles has gradually changed from an integrated heat dissipation system to an independent heat dissipation system. The heat dissipation system usually consists of a water radiator, an intercooler, a hydraulic oil radiator, The torque converter oil radiator, hydraulic pump, hydraulic motor, fan, control valve group, sensor and controller are composed of components such as the water radiator, intercooler, hydraulic oil radiator, and torque converter oil radiator. The outlet temperature adjusts the f...

Problems solved by technology

[0003] Construction machinery and special vehicles have the characteristics of many models, small batches, and a wide range of applications. As a result, there are great differences among various models, which brings many difficulties to the design of the control system and the calibration of actual vehicles. At present, the domestic In the field of independent heat dissipation control system control methods, only the patent of "hydraulic independent heat dissipation control method, device and system" with application number 201510853101.8 is involved, but this patent mainly elaborates from the temperature collection of the independent heat dissipation system to the temperature trend prediction, and then From the generation of fan demand speed to the determin
