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 determination of solenoid valve control current, a complete link temperature control scheme

However, for construction machinery and special vehicles, there are many models, small batches, and large functional differences. Each model needs to be developed repeatedly. There is no specific solution, especially in the software architecture design of the independent heat dissipation control system. Therefore, , a generalized control system is needed. Through the strict definition of control functions and the clear definition of module functions, the modular design of the independent cooling system can be completed, the rapid development of the control system can be realized, and the needs of rapid development of independent cooling systems for different vehicles can be met.
