随着船舶柴油机中油液颗粒等杂质含量的集聚，柴油机和零部件设备表面之间的摩擦愈发加剧，长此以往会加剧设备损坏，因此，提出设计一个船舶柴油机油液检测装置。本文以STM32F103ZET6为中央核心控制器，使用油液颗粒传感器、水分和温度变送器、油品质传感器、粘度与密度传感器，设计出一种船舶柴油机油液检测装置。该油液检测装置可以在线检测油液的水分浓度、颗粒物大小、颗粒物浓度等关键指标，进而可以确定柴油机油液的更换周期，确保柴油机工作时的油液品质最佳。并且，上位机可以实现在线检测，避免复杂工况，可以实时存储数据到本地电脑，方便技术人员观察。
With the concentration of impurities such as oil particles in marine diesel engine, the friction between diesel engine and equipment surface becomes more and more serious, which will aggravate equipment damage in the long run.Therefore, it is proposed to design an oil detection device for marine diesel engine. In this paper, STM32F103ZET6 is used as the central core controller, using oil particle sensor, moisture and temperature transmitter, oil quality sensor, viscosity and density sensor, a kind of oil detection device for marine diesel engine is designed. The oil detection device can detect the key indicators such as water concentration, particle size and particle concentration of oil on-line, and then determine the replacement cycle of diesel oil to ensure the best quality of oil when diesel engine is working. Moreover, the upper computer can realize on-line detection, avoid complex working conditions, and store data to the local computer in real time, which is convenient for technicians to observe.
