Description

Technical Field

[0001] This utility model relates to the field of oil monitoring technology, and in particular to an online oil monitoring device for vehicles. Background Technology

[0002] Wear failure is the most common form of equipment failure, and most mechanical equipment malfunctions are related to wear. Parameters obtained through monitoring and analyzing oil can effectively determine the lubrication and wear status of equipment. Currently, in industrialized countries, oil analysis technology is becoming, or has already become, an indispensable method for condition monitoring and fault diagnosis of mechanical equipment, achieving significant benefits in areas such as engines, gear drives, bearing systems, and hydraulic systems.

[0003] Oil analysis technology is divided into offline testing and online testing: offline testing mainly relies on manual sampling and then testing in the testing room, while online testing uses sensors installed in the mechanical equipment being tested to detect the oil. Both testing methods have their advantages and disadvantages.

[0004] Offline detection offers high accuracy, but suffers from high cost, complex operation, and poor real-time performance.

[0005] Currently, online monitoring systems are generally susceptible to the effects of harsh working environments. Online oil detection suffers from low detection accuracy, low input impedance, and weak anti-interference capabilities. Therefore, to avoid interference from uncertain factors, online monitoring must improve detection and measurement accuracy and enhance anti-interference performance.

[0006] Traditional testing methods involve manually collecting oil samples, which is time-consuming, costly, and cannot reflect vehicle operating data in real time. Furthermore, existing online sensors on the market have drawbacks such as low measurement accuracy, small range, and significant susceptibility to environmental factors, resulting in large fluctuations in test data.

[0007] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
