Embodiment Construction
[0055] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0056]It should be noted that the cooling system can be composed of pumping device (water pump or hydraulic oil pump), radiator, cooling fan, thermostat and other auxiliary devices. The pumping unit pressurizes the coolant and circulates it through the cooling system. The radiator is a heat exchanger that can be used for cooling the coolant. When the cooling fan rotates, it can suck in air ...

The invention provides a cooling system fault diagnosis method and device and an operation machine. The method comprises the steps: obtaining target operation data corresponding to a cooling system; based on a fault diagnosis model, obtaining diagnosis data corresponding to the target operation data; and based on the target operation data and the diagnosis data, judging whether the cooling system breaks down or not, wherein the fault diagnosis model is acquired in advance based on sample operation data of the cooling system. According to the provided cooling system fault diagnosis method and device and the operation machine, whether the cooling system breaks down or not is judged based on the target operation data corresponding to the cooling system and the diagnosis data obtained based on the fault diagnosis model, fault diagnosis of the cooling system can be achieved more efficiently and more simply, and the accuracy of fault diagnosis of the cooling system can be improved.
Description
technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a cooling system fault diagnosis method, device and operating machinery. Background technique [0002] During the operation of the diesel engine, in order to avoid the local overheating of various parts inside the diesel engine, it will cause the diesel engine to overheat and fail. The cooling system can cool the inside of the diesel engine and prevent the diesel engine from overheating. [0003] In the prior art, operation and maintenance personnel can realize the fault diagnosis of the cooling system by means of disassembly, visual inspection and maintenance. However, the efficiency of manual fault diagnosis of the cooling system is low, and how to perform more efficient fault diagnosis of the cooling system is an urgent problem to be solved in this field. Contents of the invention [0004] The invention provides a cooling system fault diagnosis method, device...
