Expert System for Comprehensive Transmission Fault Diagnosis Based on Oil Sensor

When armored vehicles are fighting in high-intensity environments, their integrated transmission systems are under tremendous pressure. The traditional method only detects the oil temperature and metal abrasive particles to determine whether the integrated transmission system is working properly, it is difficult to quickly locate the cause. This paper builds on the integrated oil sensor, analysis of physical and chemical indexes such as lubricating oil temperature, water mixing, pollution degree and viscosity collected by sensors. In the traditional fault diagnosis system, a new fault diagnosis system is established, which can find the fault source faster, determine the fault level of the machine, and make it easier for maintenance personnel to judge whether the machine needs to be shut down for maintenance. Fault diagnosis mainly through inference rules and a combination of qualitative and quantitative fault tree analysis, can clearly reflect the relationship between each fault and the parameters detected by abnormality. Integrated oil sensor and fault diagnosis system are appropriate for multi-model armored vehicles. In the future innovation, technical parameters can be inserted or reduced according to user need, and it has a good adaptability.
